(2)随着这些硬件的装配,需要对学校供电线路进行改造,下表是各种橡胶绝缘铜芯线在常温下的安全载流量(长时间通电时的最大安全电流),从安全角度考虑,该校应选择哪种导线作为干路导线?请通过计算后说明。 (3)该校电路中的保险装置采用空气开关(如图甲),空气开关内有电磁铁和两个触点,制作触点的材料有铜或银,电路正常工作时两触点是连接在一起的,当电流过大时电磁铁将两个触点分开,切断电路(如图乙)。从空气开关的使用寿命和安全角度考虑,应选择触点用________(填“银”或“铜”)材料制作的空气开关,原因是_______________。(同样条件下,银的电阻比铜的电阻小)   导线规格 导线横截面积S/mm2 4 6 10 16 安全载流量I/A 37 47 68 94 答案 一、1.C 点拨:在家庭电路中,电路的总开关应该接在干路中,在电能表之后,故1合理;三孔插座中,中间的孔接地,不要开关控制,故2是不合理的;三孔插座的右孔接的是火线,开关3控制的是火线,故3合理;控制灯泡的开关应该接在火线和灯泡之间,不应接在零线与灯泡之间,故4不合理,5合理。综上所述,无需设置的是2、4。 2.A 点拨:家用电冰箱正常工作时的电压等于家庭电路的电压,大小为220 V,故A符合实际;台灯电功率在40 W以下,由P=UI可得I==≈0.18 A,即台灯正常工作电流在0.18 A以下,故B不符合实际;教室里每只日光灯的功率约为40 W,故C不符合实际;家用电磁炉的功率较大,在1 000 W左右,故D不符合实际。 3.D 点拨:使用测电笔辨别火线与零线时,手一定要接触笔尾金属体或金属笔卡,不能接触笔尖的金属体,故乙、丁错误,甲、丙正确。 4.C 5.D 点拨:由图可知,闭合开关S后,灯泡正常发光,电路可以形成通路,其中a、b点与火线相连,故可以使氖管发光;而c、d点与零线相连,不能使氖管发光。 6.B 点拨:电路中甲、丁是并联的,故A错误。家庭电路中各支路是并联的,丙连接在火线上,丙和乙串联,所以丙的连接方式不正确,故B正确。闭合开关S1、S2,甲灯亮、乙灯不亮,是由丙与乙串联连接造成的,故C错误。用测电笔检测丙插座的两孔时,左孔能使测电笔氖管发光,右孔不能使氖管发光,故D错误。 7.B 点拨:用电功率计算公式来求允许的最大总功率。 8.C 点拨:根据题图可知,该接线板上有三孔插座,因此连接线有火线、零线和地线,故A错误;开关控制台灯和指示灯,而台灯和指示灯互不影响,因此台灯与指示灯并联,开关S在干路上,故B错误,C正确;从接线板上可以看出有两个三孔插座、两个两孔插座,因此有四个插孔与火线相连,即四个插孔能使测电笔氖管发光,故D错误。故选C。 9.D 点拨:开关接在灯泡和零线之间,当断开开关,火线和灯泡还处于连接状态,人接触灯泡就是间接接触火线,容易触电,故A不符合题意;与家用电器金属外壳相连接的是地线,这样即使金属外壳带电,电流也会通过地线导入大地,防止触电事故的发生,不能用两孔插座替代,故B不符合题意;使用测电笔时,手一定不能接触笔尖金属体,如果测电笔接触火线,手接触笔尖金属体会发生触电事故,故C不符合题意。发现有人触电时,应赶快切断电源或用干燥木棍将电线挑开,不能用手直接拉,防止也触电,故D符合题意。 10.A 点拨:因为相同情况下,铜丝的电阻小、熔点高,在电流过大时,产生的热量不足以达到熔点,因此不会熔断,起不到保险的作用,故A不符合安全用电原则;安全用电的原则是:不接触低压带电体,不靠近高压带电体,故B符合安全用电原则;不要在大树下避雨,因为此时大树和人体都是电的良导体,雷电极易通过突起的大树传向人体,而造成雷电灾害,故C符合安全用电原则;使用测电笔辨别火线时,用手触及测电笔笔尾金属体,才能辨别出火线、零线,手不能接触笔尖金属体,否则会发生触电事故,故D符合安全用电原则。 11.B 12.D 点拨:甲站在干燥的木桌上一只手接触到火线,无法形成电流的通路,故不会发生触电;乙站在地上一只手接触到零线,零线与大地之间没有电压,因此没有电流通过人体,不会发生触电;丙站在干燥的木桌上一只手接触到火线,此时,丁站在地面上用手去拉丙,这样电流可以从火线经丙、丁导向大地,会造成丙、丁两人同时触电。综上所述,甲、乙都不会触电,丙、丁都会触电。故选D。 二、13.火线;短路 14.大地;台灯所在的支路开路 点拨:电水壶接入电路时需用三孔插座,将其用电部分连入电路的同时,也将它的金属外壳与大地相连;它与两孔插座上的用电器并联,当将台灯连接在图中两孔插座上,闭合开关后台灯不亮,说明台灯所在的支路开路。 15.短路;过大 点拨:电流过大会导致空气开关“跳闸”,电流过大的原因有:①电热水壶插头内部发生短路; ②接入电热水壶后使得电路中用电器的总功率过大,造成干路电流过大。 16.③④①② 点拨:当断路器中的电流过大时,双层金属片发热过多,双层金属片会向右弯曲,触动簧锁装置,簧锁装置会脱开,于是触点断开,对电路起到保护作用。故合理的顺序是③④①②。 17.(1)并;火;绝缘体 (2)额定功率是25 W;0.5 18.400 点拨:电压相等,后一种情况的电阻是前一种情况的400倍,所以前一种情况的电流是后一种情况的400倍。 三、19.解:如图所示。 20.解:如图所示。 四、21.解:(1)I=5 A时,超导限流器电阻为0,用电器X消耗的电功率P=UI=220 V×5 A=1 100 W。 (2)X被短路后,为使电路保持稳定状态,超导限流器电阻不能为0,I′≥20 A,故有R=≤=11 Ω,所以0

由W=Pt可得,消耗0.01度的电能,灯泡工作的时间:t===10 h。 15.减速;金属棒切割磁感线产生感应电流,则金属棒的一部分动能会转化为电能,最终转化为内能,动能减少,速度减小 点拨:金属棒滑到水平导轨上后,金属棒做切割磁感线运动,产生感应电流,即动能转化为电能;由于导轨和金属棒有一定电阻,电流流过导轨和金属棒会产生热量,所以电能又转化为内能,导致金属棒的动能越来越小,最后动能为0,金属棒静止,所以金属棒做的是减速运动。 三、16.方向;电;电动机 点拨:给直导线通电,发现它向右运动,磁场方向不变,只改变直导线中电流的方向,发现它向左运动,导线的运动方向发生改变;此过程中,消耗电能,产生机械能,将电能转化为机械能,电动机就是根据此原理制成的。 17.通电导体在磁场中受到力的作用 18.(1)奥斯特 (2)能;不能;全部刮去;半周(或一半) ①改变电流方向(或将电源两极对调);改变磁场方向(或将磁体两极对调) ②C 19.(1)无 (2)①切割磁感线 ②导体的运动方向 (3)会 点拨:(1)导体ab静止悬挂,闭合开关,灵敏电流计的指针不偏转,说明电路中无电流产生。 (2)①比较1、2(或1、3)实验现象可知,当闭合电路的一部分导体在磁场中做切割磁感线运动时,电路中就会产生感应电流; ②比较2、3实验现象还发现,产生的感应电流的方向跟导体的运动方向有关。 (3)若在整理器材时未断开开关,先水平向左撤去蹄形磁铁(导体ab不动),那么以磁铁为参照物,导体ab相对于磁铁水平向右运动,等效于用导体ab切割磁感线,所以灵敏电流计的指针会偏转。

A. 14 RMB B. 12 RMB C. 11 RMB D. 13 RMB B Do you know when and where ice cream was created? It has a long and interesting history. The earliest ice cream was eaten in China many centuries ago. People at that time would put orange juice on the ice or get something cool to drink. Later, this idea travelled to Italy. Around 1660, it was popular to serve ice cream in coffee shops in Paris. Most of the shops were owned by Italians. Among them, the first successful one belonged to (属于) a man named Francesco Procopio. Ice cream was brought to America in the early 1700s, and it quickly became the favourite of Americans. President George Washington had ice cream pots (罐) and machines in his kitchen. Dolly Madison, the wife of President Madison, was the first one to serve it in the White House. She made her guests very happy when she served such desserts (甜品). Before ice cream was sold in stores, it was made and kept at a very low temperature first. It took a lot of work to mix cream, eggs, fruit and ice. Nancy Johnson, an American woman who was good at machines, invented the ice cream freezer in 1846. Five years later, Jacob Flusell opened the first ice cream factory in Baltimore, Maryland. Her business quickly came to other states. Today in the United States, ice cream is not only a kind of food, but also a way of life. 59. The earliest ice cream was the ice with ____ on or something cool to drink. A. orange juice B. apple juice C. watermelon juice D. pear juice 60. The underlined word “freezer” means “____” in Chinese. A. 品种 B. 冰柜 C. 配方 D. 厨房 61. Which of the following is TRUE? A. In 1700, ice cream came to the White House. B. In 1846, many ice cream factories opened. C. Today ice cream means a lot to Americans. D. You should keep ice cream in high temperature. 62. The best title for this passage is “____”. A. The History of Ice Cream B. Ice Cream in America C. Business on Ice Cream D. The Invention of Ice Cream C Can you imagine walking in, sitting next to a stranger and asking for the latest news or putting a recent novel down next to someone's coffee and asking for their opinion before giving yours? But more than 300 years ago, this kind of behaviour was encouraged in thousands of coffee houses all over London. In 1712, the Starbucks site(位置)today was occupied(占据) by Button's coffee houses. Inside, poets, writers and members of the public gathered around long wooden tables drinking, thinking, writing and discussing literature into the night. On the wall, near where the Starbucks community notice board now stands, was the white marble(大理石)head of a lion with a wide?open mouth. The public was invited to feed it with letters and stories. The best of the lion's digests(文摘)were published in a weekly edition of Joseph Addison's Guardian newspaper, named “the roaring of the lion”. Today, few people know Button's. It's just one of London's forgotten coffee houses. London's first coffee house was opened by a Greek named Pasque Roseé in 1652. While a servant for a British merchant in Turkey, Roseé developed a taste for the exotic(异国情调的)Turkish drink and decided to import(进口)it to London. People from all walks of life came to his business to meet, greet, drink, think, write, and joke. 63. Where was the white marble lion's head? A. In the backyard of Starbucks. B. On the Button's long wooden tables. C. In Joseph Addison's Guardian newspaper. D. On the wall of Button's coffee houses. 64. What kind of coffee did Pasque Roseé import to London? A. Turkish coffee. B. Black coffee. C. White coffee. D. Sweet coffee. 65. What can we infer (推断)from the passage? A. People could hardly find a coffee house in 1712 in London. B. Starbucks, Button's and Roseé were famous coffee houses of London in the 1700s. C. Button's was usually noisy and crowded at night more than 300 years ago. D. Only businessmen enjoyed the exotic coffee at Pasque Roseé. D Autumn is the best season for crabs. The hairy crabs (大闸蟹) are quite fat and tasty at this time of year. The best crabs come from Yangcheng Lake in Jiangsu. Many people use eight silver tools including chopsticks, a pair of scissors and a small hammer (锤子) to eat crab meat. Caviar (鱼子酱) is not common in most people's daily life. But if you're going to try it, Russian caviar may be your best choice. Caviar is made of fish eggs. It sells at a high price. If you want to get the fresh juicy taste, don't cook it- just eat raw caviar. You may also eat it with bread and salad. Who says the British only have fish and chips? Beef Wellington is a dish that they can truly be proud of. An expensive cut of beef is covered with a mixture first. Next comes another piece of ham (火腿) and pastry (面糊). Then it is covered with eggs. Baked (烘焙) until it is golden yellow, beef Wellington tastes crispy outside and juicy inside. Sukiyaki (寿喜锅), or Japanese beef hot pot, is one of the most popular dishes in Japan. People cook beef and vegetables in soup with sweet and salty tastes. It is a perfect dinner for family or to enjoy with guests. In Sukiyaki, you need thin pieces of beef. The best is the Kobe beef. It's very expensive but amazing. 66. There is beef in ____. A. the hairy crabs and caviar B. Sukiyaki and beef Wellington C. caviar and Sukiyaki D. beef Wellington and the hairy crabs 67. The four foods in the passage come from ____ countries. A. one B. two C. three D. four 68. Which of the following is RIGHT? A. Crabs come from Yangcheng Lake. B. Caviar is common in most people's daily life. C. Beef Wellington is the pride of British people. D. Sukiyaki is a perfect dish only for family. E In the eyes of many foreigners, Chinese are the best hosts and the worst guests in the world. And Western hosts sometimes look rude (粗鲁的) in the eyes of Chinese guests. It is because the guest?host relationship in China is quite different from that in some Western countries. In China, guests are almost like gods. Whenever I enter a Chinese friend's home, there is always fruit on the table for me, and someone is quick to bring me a cup of tea or water. In the West, generally the guest is not a god. Acting according to the host's way of doing things is usual behavior for a guest. My wife's mother, a very kind Chinese lady, doesn't smoke. When I see some of her guests smoking in her house, as a non?smoker, I feel unhappy. Usually, I want to stop them directly, but I must realize that in China, to be a good host, she must not do that. In most North American homes, if you are a guest, and the hosts are not smokers, you should not smoke in their house. At the very least, you should ask, “Is it OK if I smoke?” But don't be surprised if they say “No, you can't smoke. ” In my culture, if you smoke in their house, you are a bad guest; but if they don't allow you to smoke in their house, they are not rude hosts. In a word, no matter where you are, the best way to be a good guest is to adapt to (适应) the habits of your hosts. 69. When a Western guest visits a Chinese family, he often ____. A. buys some fruit B. brings a cup of tea C. smokes D. feels like a god 70. What will the writer probably say if a guest wants to smoke in his house? A. Let's smoke together. B. Sorry, you can't smoke here. C. Smoking is a bad habit. D. It's OK if you smoke here. 71. What can be learned from the passage? A. A friend in need is a friend indeed. B. Where there is a will, there is a way. C. When in Rome, do as the Romans do. D. Actions speak louder than words. 72. What is the best title of the passage? A. The Best Hosts B. The Best Guests C. Different Cultures in Different Countries D. Different Guest?host Relationships in Different Cultures 阅读下面的短文,并用英语回答问题(请注意每小题后面的词数要求)。 F “May we all be blessed with longevity. Though miles apart, we are still able to share the beauty of the moon together (但愿人长久,千里共婵娟)” was written by Su Shi,a poet during the Song Dynasty. His well?known poem was written to his younger brother Su Zhe. The moon is at its brightest on the 15th day of the eighth month of the lunar calendar(阴历). On this day, people celebrate Mid?Autumn Festival. It has been enjoying great popularity all over the country. In ancient China, that day was a harvest (收获)festival because crops(庄稼)were harvested during that period. It was a time for relaxation and celebration. Just like Thanksgiving in Western countries, families also try to get together for the Mid?Autumn Festival in China. Usually, no matter how far away or how busy they are, people will try to return home for the celebration. The Mid?Autumn Festival has its own special food just as other traditional Chinese holidays. People eat moon cakes with fillings such as sugar and eggs. The round shape of the cake makes it look like the full moon. The full moon and moon cakes stand for family reunion(团聚). With the beautiful moon up in the sky, people sit together, enjoy the full moon, eat moon cakes and fruits, share the stories, and express the best wishes for the family members and friends who live far. 73.

They have breakfast at any time from seven to nine in the morning. They usually eat eggs or bread and drink tea or coffee for breakfast. Lunch usually comes at about one o'clock. Some of them eat in the restaurant, and some of them eat at home. Afternoon tea is from four to five. Supper is at about half past seven. In some families, they like eating well in the evening, because they are usually very busy in the day. First they usually have soup, and then they have meat or fish with vegetables for the big meal. After that, they eat some other things like bananas, apples or ice cream. 四、   Last weekend, after finishing my homework, I wanted to relax myself, so I went to the cinema to watch Journey to the West with my friends. I hoped to enjoy ourselves there. However, some of the people there made me feel very unhappy. When we arrived there, the movie had been on for ten minutes. We found our seats quickly and sat down. What's worse, a few guys were talking loudly or even shouting when they saw some exciting pictures. Also, some people threw away plastic bags, paper and other rubbish on the floor. It made the floor very dirty. As we know, the cinema is a public place where we can have a nice time. All of us are supposed to obey the rules in public. Only in this way can we make public places more comfortable. 听力答案: 一、1~5:CBBBC 二、6~10:CACAB 三、11~15:BACAB 四、16. friends 17. unhappy 18. talking  19. paper 20. public 第二部分 英语知识运用 五、21.

So I think you may not know some table manners. OK, let me tell you about some of them so that you will not feel uncomfortable when you have meals with the English. When you are invited to have a meal, bringing some flowers, chocolates or a bottle of wine as a present is polite. And it's polite to say how much you like the food and the drink. But remember not to ask how much the things cost. Also, it's polite to finish everything on your plate and take more if you want. This is different from China. I hope you will have a happy visit here. Your friend, Lucy

Here are the things you should know. ●Take precautions(预防措施) after an unusual activity. Many people report having a pain in their necks after doing something that they don't often do, such as a new exercise or packing and moving. If you know you've done something that puts you at a risk, massage (按摩)your neck, do it with different exercises and take a warm bath before bed. ●Make sure your workstation is correct. If you work long hours at a desk, you may want to make sure that your work environment is set up to be the most relaxing. Make sure that your body is being treated right. Keep your feet on the floor. This will often depend on how high your chair is, so adjust(调整) it in time to achieve good results. ●Change your posture often. Sitting in one position for long periods of time is not healthy. Sit with your back straight for most of the time. Take a 5?minute break if you can and walk around every hour. ●Exercise. Find something—swimming, running or climbing—that makes you excited and feel alive. Make it into a usual way. Your body will feel better and your mind will feel more relaxed. 59. The underlined word “posture” in Paragraph 6 probably means “____” in Chinese. A. 姿势 B. 方向 C. 方式 D. 状态 60. ____ can avoid a sore back according to the passage. A. Making your work environment quiet B. Sitting with back straight for a moment C. Packing and moving for a long time D. Exercising often like swimming or running 61. After doing something unusual, you may do the following things except ____. A. doing it with different exercises B. massaging your neck C. taking a warm bath before bed D. looking at your phone for too long 62. This passage mainly tells us ____. A. how to do exercise well B. exercising is often good for people C. how to avoid a sore neck D. being healthy is the most important C Humans can go to the hospital when they're ill. But as for animals, what should they do? To stay healthy, animals have their own ways to heal (治愈) themselves. Now let's get to know their special skills. Skill One Have you ever seen your dog or cat lick (舔) its wounds? Why do they do it? It probably feels good, but it's good medicine. Licking cleans a wound, and saliva (唾液) has chemicals that kill germs (细菌). Skill Two To avoid diseases, many animals have good living habits. They hate to be dirty. Most animals separate their pooping (排便) areas from their eating areas. Horses poop far away from the grass they eat. Rabbits put their poop in special pooping areas. Skill Three Have you ever heard of the expression “starve a fever (发烧时宜饿)”? Many animals stop eating when they're ill. When a sick animal stops eating, it can stop germs from getting necessary things. Skill Four Another way that animals heal themselves is to raise their body temperature. High temperature can kill germs. Warm?blooded animals (like us) get fevers to fight with germs. Cold?blooded animals (like snakes) look for pieces of wood or rocks heated by the sun. Fish move to warmer waters. 63. In order to avoid diseases, horses and rabbits ____. A. eat special grass B. choose dirty areas C. put poop into holes D. have good living habits 64. Fish move to warmer waters to ____. A. lick their wounds B. keep themselves clean C. starve a fever D. raise their body temperature 65. We may find the passage in a (n) ____. A. advertisement B. magazine C. travel guide D. storybook D Have you tried to run or walk for exercise and then given up? If you answered yes, you should try a new kind of exercise:aquatic (水中的) exercise. Aquatic exercise is like exercising on land, but you do it in a swimming pool. More and more people are trying aquatic exercise. Aquatic exercise feels easier than exercising on land. Why? You weigh about 90% less in the pool. It is better for your knees than running or walking. Water is about 1,000 times thicker and heavier than air. To move through the water, your body has to work four times as hard. As a result, you can burn more calories (卡路里). In fact, most people say they feel more relaxed in the water. They stop thinking about the things that make them worried. They feel in control of their bodies. The cool and quiet environment makes them feel good. But what if you are afraid of the water? No problem! There is nothing to worry about. Aquatic exercise is safe and easy to learn. It doesn't require any special skills. You don't even need to know how to swim. Aquatic exercise is for everyone. 66. What is Paragraph 2 mainly about? A. Differences between air and water. B. Weight changes of one's body. C. The advantages of aquatic exercise. D. The ways to do aquatic exercise. 67. What do most people think of aquatic exercise? A. Relaxing. B. Worrying. C. Challenging. D. Boring. 68. In which part of a magazine can we read the text? A. Culture. B. Health. C. Nature. D. Travel. E “I'm going to bed earlier tomorrow!” But no matter how we decide, there are still many chances that we break our promises. This behavior is called “bedtime procrastination” (睡眠拖延症), and results from being short of self?control and our body clock. Bedtime procrastination is a common problem. According to a study, among 2, 400 people, 53 percent of them couldn't follow their sleeping time they had planned, delaying (推迟) it at least twice a week. They delayed bedtime not because they liked to stay up late, but they couldn't stop doing some other things. Accordingly, people who usually have trouble resisting temptations (抵制诱惑) and adhering to their intentions (坚持己见) are more likely to delay going to bed. However, scientists think being short of self?control is not the only problem. Our body clock also plays an important role when it comes to bedtime. In order to check the influence of the body clock on sleep, scientists studied the sleep patterns (模式) of 108 people. It was found that those who got up late are more likely to delay their bedtime than those who woke up early every morning. And more surprisingly, night owls (夜猫子) would go to bed late at the very beginning of the weekday, even though they had to get up early for work and school. It's their special body clock that plays a part in delaying their bedtime. People always think that bedtime procrastination isn't a big problem, but the choices we make that affect (影响) our sleep could finally be pretty important for our health. 69. Bedtime procrastination is partly because of ____. A. being short of self?control B. resisting temptations C. adhering to their intentions D. working hard 70. Bedtime procrastination is a common problem because ____. A. people liked to stay up late B. people have trouble going to bed C. over 50% of people couldn't sleep on time D. people are night owls 71. According to the passage, which of the following is NOT true? A. People who got up late are more likely to delay their bedtime. B. People who woke up early may not delay their bedtime. C. Night owls always got up late. D. Night owls delayed their bedtime due to their special body clock. 72. The writer implies (暗示) that bedtime procrastination ______. A. is not a big problem B. has no any influence on our body C. is the choice we make D. is harmful 阅读下面的短文,并用英语回答问题(请注意每小题后面的词数要求)。 F It's 4 a. m. , and the big exam is in eight hours. You've been studying for days, but you still don't feel ready. What can you do? Well, you can drink another cup of coffee and spend the next few hours reviewing, but believe it or not, you might be better if you close the books and go to sleep. Sleep takes up nearly a third of our lives, but many of us pay little attention to it. The misunderstanding causes this. Sleep is a waste of time, or just a way to rest when all our work is finished. Instead, it's a very important process, during which your body balances and regulates(调节) its many systems, such as breathing, blood, immune(免疫) systems. . . Also it's necessary for our growth. You may worry about the exam, right? Well, it turns out that sleep is also important for your brain—a fifth of your body's blood runs into it as you are asleep. And while you sleep, your brain keeps working actively, which is a helpful period for improving your memory. When we lose sleep, learning, memory, mood and reaction time are affected. Sleeplessness(失眠)may also cause many diseases, like high blood pressure, diabetes(糖尿病), obesity, etc. It's certain that sleep is a necessity if we want to keep our health and clearness. 73.

The school bell rang. I entered the classroom nervously. The teacher welcomed me and asked me to sit beside a girl named Annette. Everyone was friendly and wanted to be my first friend. I was surprised. Then we started the lessons. Annette helped me find the pages and showed me what we were doing. It was the same kind of math I learned at my old school. The reading book was different. It had new stories in it. At lunch time, Annette asked me to stay with her in the line, so she could show me where everything was. She also introduced me to her friends and we ate lunch together. In the afternoon, we had free reading time. I read with my new friends. I was glad to have met them. At the end of the day, we got homework and left school. What a great day! 四、Dear Lucy, I'm sorry to hear that you have poor eyesight. You should learn how to protect your eyes.

He asked his students to hand in their homework through a QR code (二维码). “We spent an hour or two in class learning how to generate (使产生)the codes,and in the end everything gets easier,” said Guo. “When students finish the homework, they keep it on WeChat (微信). Then, each student makes his own QR code and gives it to me. So I can check their homework everywhere using my computer or telephone. ” The QR codes can be sent to Mr Guo by email, QQ and WeChat. When Guo scans (扫描)his students' QR codes,their homework appears on his phone. He finds that their homework becomes more creative (创新的),with many pictures, music and even videos. Guo's students like the new way and think it is interesting. “We are living in the information age. Many students like to work with computers, which makes learning more fun,” said Tingting, a student of Guo's. “The paper is not easy to keep, but the code is easy to keep and share,” Guo said. “It is worth trying to use new technology in education. Education itself is a kind of creation. I don't want my students to fall behind the times. ” However, some parents are worried. They are afraid that their children will spend too much time on computers and less time communicating with teachers. But in fact, it's unnecessary. Students still need to look up information in books and write it down when they do their homework. They only use the code when they hand in their homework, which doesn't take them too much time. Also for teachers, it allows them to check the students' homework at any time. And it's also an easy way to share homework with other students. 59. According to the passage, students can keep their homework on ____. A. WeChat B. QQ C. email D. blog(博客) 60. What does the underlined word“It” in Paragraph 4 refer to (指代)? A.

Some parents are worried, because they think their children will ____. A. talk with teachers face to face B. spend too much time on computers or phones C. not like the new way of handing in homework D. find the QR codes too difficult to use 62. What's the main idea of the passage? A. Teachers needn't check homework any more. B. Students needn't hand in homework any more. C. Using QR codes makes checking homework easier. D. Some parents are worried about their children. C On my recent trip to Sydney with my parents, we visited the Wildlife Park. The Wildlife Park has lots of different animals and birds. Some are native(当地的) to Australia and can only be found there. There are over 600 animals there, including kangaroos, koalas and crocodiles(鳄鱼). They are kept in their natural environment. I like the Wildlife Park better than a zoo where most of the animals are in cages(笼子). We first spent some time with the kangaroos. We were allowed to touch and feed them. It was very exciting to be so close to them. There were koalas there too. They looked very cuddly(令人想拥抱的). Although we were not allowed to carry them, I got to take a photo with one. It is a wonderful souvenir(纪念品) of my holiday in Sydney. The Wildlife Park has plenty of freshwater and saltwater crocodiles. Some of them are really big and scary(吓人的) with huge teeth!

A. 4:20 on Friday afternoon B. 4:30 on Sunday afternoon C. 6:00 on Saturday morning D. 8:40 on Wednesday morning B Have you ever heard the phrase “You never get a second chance to make a first impression (印象)”? It may sound like an unusual piece of advice, but it is true—the first impression someone has of you when meeting you for the first time will probably influence how that person treats you or reacts to you in the future. What is even more interesting is that the brain takes in all the information to create that first impression in about three seconds. When you meet someone for the first time, by the time you have stated your name or shaken hands, the other person has already formed an opinion about the kind of person you are. So how do you make a good first impression? All things grown?ups tell you—such as being polite and being well?dressed—are very important. However, the most important tool for making a good first impression is your face. Smiling, being responsive, and looking like you are happy will almost always leave a positive (积极的) impression on people, especially those who do not know you. Most people, generally speaking, are ready to smile back when they are smiled at. Furthermore, smiling and being in a positive mood helps you to know and get a better understanding of new things. 'This means that you can possibly be friendlier to people you do not know and be more creative and able to solve problems more quickly. So if you ever need a reason to be happy, think about the wonderful people you might meet—and impress—with a cheerful smile. 59. What does the underlined word “reacts” in Paragraph 1 probably mean in Chinese? A. 回应 B. 道歉 C. 报告 D. 建议 60. What is the most important for leaving good impressions? A. Shaking hands. B. Stating your name. C. Dressing nicely. D. Wearing a smile. 61. What can be learned from the last paragraph? A. Friendliness helps solve problems. B. Being positive helps you find a way out. C. There are many reasons to be happy. D. Thinking of great people cheers you up. 62. What would be the best title for the text? A. The First Impression Does Count B. Smiling Makes the First Impression C. Manners Leave Deep Impressions D. Impressions Decide Who You Are C People are always trying to live a healthy life. You might have read so much on this topic. The following ideas may sound strange but they can really help you. Exercise when you are tired. After a long and tiring day of study, exercising might not sound like a good idea, but it should. In fact, physical activities can provide you with the missing energy. Research shows that exercising for just 30 minutes can make you feel good! Write by hand to help the brain be active. Although writing something using a computer is faster, it is much better to remember the whole thing by writing it down by hand. When you read a handwritten text naturally, it's easier for your brains to remember the information. Spare more time for yourself. By sparing the time for yourself and just being alone for a while, you can have a chance to think and get to know yourself better. And you won't behave impulsively (冲动地). Drink hot drinks on a hot day. What cools more on a hot summer morning, cold water or hot water? The study shows that the hot water does make people feel cooler. When you are drinking something hot, the body will feel the change in temperature and increase the perspiration (流汗), which helps you cool down! 63. The third idea is mainly about ____. A. the advantages of being alone B. the importance of thinking C. the advantages of behaving well D. the importance of keeping healthy 64. Why do we drink hot water on a hot day? A. Because it brings heat to our bodies. B. Because it is harmful to our bodies. C. Because it makes our bodies strong. D. Because it takes heat away from our bodies. 65. The writer of the passage wants to tell us that ____. A. handwriting makes us smart B. hot drinks can make us uncomfortable C. being alone helps us know our friends better D. sometimes unusual ideas about health are helpful D It is not very easy to last a friendship with someone you cannot see or feel. This is the main problem that Internet friendship faces. Without the real communication, it is very difficult to form a friendship that would last forever. And the chances of cheating are very high in an Internet friendship. So while making friends on the Internet, one has to be very careful and follow certain precautions (防范). There are some suggestions followed if you are going for online friendship. Tips for online friendship: ★Do not disclose(公开) personal information to unknown people on the Internet, such as your telephone number, address, location,the jobs of your parents, your credit card number etc. If you feel you are cheated, telephone the police at once. ★Disconnect (断开)the line if you feel the person is trying to know something important about your personal life. ★Do not disclose anything about your friends or relatives or other family members. ★Do not exchange your photographs on the Internet. ★Do not go to meet a person you have just met on the Internet. Consult elder people or someone who is experienced and if you have to go, take someone reliable with you. 66. Making a true friend on the Internet is ____. A. easy B. boring C. necessary D. difficult 67. How many suggestions are there for online friendship? A. Six. B. Four. C. Five. D. Three. 68.

Abby was going to be away for three months. “I can't leave Tobias behind,” she said. “You will have to,” said her father. “You can't take Tobias into another country. ” Abby thought it was a silly rule. “I will take him,” she said to herself. So she put him in a sock and packed it in her bag. At the airport, Abby put her bag by the X?ray machine. Abby felt her legs shaking as the bag was going through the machine. She hoped Tobias in the bag made no noise. The woman by the machine smiled and said, “Have a good flight. ” On the plane, Abby waited until her dad and the woman next to her fell asleep. Then she opened the sock to look at Tobias. But he jumped out of the sock and landed on the woman's knee. The woman cried loudly, “A mouse!” Abby quickly put Tobias into the sock and back into her bag. Before they landed, Dad filled out a form, choosing no to: Are you bringing any live animals into the country? She saw the man frown (皱眉) as her bag went through the X?ray machine. She watched when he opened the bag and pulled out the sock. “Come with me, please. ” Abby followed her dad into a small room. There was a police officer and Tobias in the sock was on the desk. The police officer talked to Abby's dad, “You have tried to smuggle (走私) an animal into this country. ” Abby felt fear came all over her body. “It's my fault (过错),” she said in a small voice. “I didn't want to leave him behind. ” “Have you ever been in trouble before?” the officer asked as he wrote “animal smuggler” next to her name. Abby opened her mouth but no sound came out. Tobias had to be in quarantine (隔离) for six months, which cost a lot of money. And Abby wouldn't be able to visit her grandmother again.

Sometimes, you feel so angry that you really want to teach somebody a lesson. But being angry can't solve problems. Neither can a fight. Instead, it may bring you more problems. In the school, everyone involved (卷入) in a fight will be punished, no matter who started it. There are no winners in a fight. Shout loudly. If you know someone is coming up behind you to attack, turn toward the person with your hands up in front of your body and loudly say “stop” before walking away. Loud voice can usually make the attacker calm down. If the person doesn't stop, cry for help by calling out the name of a teacher whose office is nearby. Learn to refuse. Your friend may ask you to join in a fight. Learn to say no. Helping him fight is not really helpful to him. If you really want to give him a hand, try to ask him to give it up. Also, you can tell him if he gets involved in a fight, he may get hurt and be punished. Then, try to learn why he wants a fight and help him find a right way to deal with the problem. 56. The underlined word “attack” in Paragraph 3 means “____” in Chinese. A. 拥抱 B. 攻击 C. 阻止 D. 吸引 57. The passage is written to ____. A. help students keep away from fights B. warn students not to fight C. advise students to help each other D. encourage students to work hard 58. The passage is written in a/an ____ tone (语气). A. sad B. angry C. serious D. crazy B Recently, a video story has spread among people. James Anthony has cleaned the halls of Hickerson Primary School for 15 years. Although he is deaf, he never complains (抱怨). Instead, he greets every child and teacher with a smile. Teachers and children love him very much and call him Mr. James. On the day Anthony turned 60, the school wanted to give him a very special surprise. That day when Anthony walked into a classroom, a group of children started to sign (打手势) and sing “Happy Birthday” to him. Anthony started smiling as usual. Then his jaw (下巴) dropped open and he laughed for joy as he realized what was going on. A few teachers led the kids through the whole song as Anthony watched. A wide smile was on his face. As they finished, tears came out from his eyes. Scott, secretary (秘书) of the school said, “The children love and respect Mr. James. They give him high fives in the halls, and he even teaches them sign language. Today he has put smiles on faces all around the world. ” 59. When did James Anthony get a special surprise? A.

That's the sound that kids all over the country hate to hear—the alarm bell. The new school year has just started and children across the UK have to wake up early in the morning to go to school. But students at one school in north?east England are lucky. They can lie in bed for an extra (额外的) hour before they go to school. Monkseaton High School has been allowing its pupils to come into school an hour later than other schools. The headmaster, Dr. Kelley, says that this new approach(手段) helps students pay more attention to their lessons in class. He feels that young people are more energetic and can perform better for the rest of the day. And he adds that for their school students, a late start at school may be better than an early one. Dr. Kelley tells the BBC that teenagers don't perform very well in the morning and their need to sleep is biological (生物的). It seems that this new approach to teaching shows positive (积极的) results. The number of students who sleep in class drops quickly. Besides, the school has already seen a drop in the number of pupils who play truant (逃学) by 27%. More importantly, Dr. Kelley also says that exam results have improved by 20%?30% over the past year. Classes at Monkseaton High School begin at 10 a. m. and finish at 3:40 p. m. However, the school opens from 8 a. m. to 5 p. m. The students can come early and leave late if they want. 63. This passage is ____. A. a news report B. a speech C. a story D. a notice 64.

A war had just ended there and left many children living on the streets. They were often forced to work at hard physical jobs for little money. One day, while walking down a country road, Doyne saw a little girl breaking up rocks. She soon learned that 7?year?old Hima sold the rocks to support her family. With deep sadness, she decided to pay Hima's tuition (学费) for school. Encouraged by the changes in the child, Doyne thought, “If we can help one child, why not 10?” Doyne felt that the street children's greatest need was a home. She found a piece of land for sale and bought it with $5,000 she saved from years of babysitting (当临时保姆) . In 2008 the Kopila Valley Children's Home was set up. With the help from the community, another goal was reached in 2010—the Kopila Valley School. Over 350 children now attend the school and over 50 live in the home. Today, Doyne lives in the home and is “Mum” to the kids. 69. When did Maggie Doyne travel to western Nepal? A. In 2006. B. In 2007. C. In 2008. D. In 2010. 70. Why did Hima break up the rocks? A.

Over 5,000 children attend the Kopila Valley School. 72. Which of the following might be the best title for the text? A. Maggie Doyne—A Lonely Traveller B. War in Western Nepal C.

It is just as strong as traditional helmets, but it can be folded almost completely flat, making it easier to carry. Morpher may be available for sale in stores in the near future. HyperAdapt Have you ever seen the movie Back to the Future? Maybe everyone wants the pair of shoes in the movie that can tighten or loosen by themselves. Now, thanks to the Shoe Factory, the dream is realized. When you push a button on the shoe, HyperAdapt can tighten or loosen around the feet. Flyte Flyte is a light bulb that can float(飘浮)and turn. Flyte has been popular with most people since it came out in January. The company also introduced a lot of similar products, including a planter, Lyfe, which came out in June. Little Printer It looks lovely and is called Little Printer. This machine can print news headlines(摘要), riddles and other things on a roll(卷)of paper.

We're a non?profit organization. We have volunteer jobs of all ages. Anyone, from twelve?year?old children to people in their seventies can become a volunteer. You can help people in many ways. Schools need help with taking care of children while parents are working. Hospitals need volunteers to look after children while their parents are seeing a doctor. Animal lovers can help take care of those dogs and cats without homes. There is something for everyone. “As a volunteer, I don't want to get anything. Seeing the children's happy faces, I'm happy, too,” said Carlos Domingo, an old woman of 62. “I often played computer games in my spare time before. Now I help older people learn how to use computers,” said another volunteer at the age of 18. If everyone helps out a bit, we'll have a better world to live in. Interested? Call us at 1800 5555 756 or visit our website: www. activol. com. 59. When do the volunteers help others? A. In their spare time. B. At weekends. C. On weekdays. D. In the evenings. 60.

A. in a newspaper B. in a storybook C. in a picture book D. in a textbook C Cars make our lives more convenient. But they can also be a problem. For example, fossil fuel (化石燃料) cars mainly cause air pollution. To improve the environment, many countries are developing electric vehicles(EVs,电动车). Among them, China is taking a leading role and has created the world's largest EV market. Last year, over 40 percent of the 753,000 EVs sold in the world were sold in China, more than twice as many as the number sold in the United States. “Filling up a fossil fuel car with gas(汽油) is more expensive than charging(充电) an electric car,” said Wu Hao, who bought an electric car this year. However, there are still some problems. It can be hard to find charging piles (充电桩) and the cars can't go far before needing to be recharged. Some of these problems are being solved. In 2014, China had 31,000 charging piles. Now China has the world's largest EV charging network, with more than 167,000 charging piles in total. Developing EVs is one of many efforts that China has made to cut down pressure on its environment after the government promised to stop increases in carbon dioxide emissions (二氧化碳排放量) by 2030. “As China goes, so will the world's car industry,” The Wall Street Journal said. China has taken a leading role in the world's electric vehicle industry. 63. What did Wu Hao think of charging an electric car? A. It's more expensive than filling up a fossil fuel car with gas. B. It's less expensive than filling up a fossil fuel car with gas. C. It's as expensive as filling up a fossil fuel car with gas. D. It's as cheap as filling up a fossil fuel car with gas. 64. Which country has the world's largest EV charging network now? A. America. B. Germany. C. China. D. England. 65. What is the passage mainly about? A. China has taken a leading role in the world's electric vehicle industry. B. Electric cars will disappear in the future. C. There is no problem using electric cars. D. How to deal with air pollution. D 5G networks have been considered as one big thing for this century. They allow people to get faster services. Downloading information takes only seconds, instead of minutes. But no true 5G phones are able to be used now. It won't work with 5G until such services are built. Users will need an adapter to bring in 5G signals. There's completely no need for users to worry about the safety of 5G signals. Where will we probably see 5G first? The answer is in our living rooms. The speeds, about 20 times faster than the standard home Internet connection, are very likely to do wonders in our living rooms. Many users are tired of spending $100 or more monthly in booking cable (有线的) TV. They no more choose cable TV and begin to use streaming (在线播放) services connected to their broadband (宽带) service instead. Besides faster access, connectivity might get a little cheaper in future for users only if a complete 5G network is set up. However, the cost of programs and apps will go up. Meanwhile, users are in great need of ordering more monthly services. Comparatively speaking, users are likely to pay more for 5G services. So far now, it's mainly used at home. . . 66. Why are no true 5G phones used today? A. Because services are not limited. B. Because special equipment isn't built yet. C. Because 5G signals are not strong enough. D. Because the safety of 5G signals is not for sure. 67. What will the writer probably write about next? A. 5G's role. B. 5G's history. C. 5G's influence. D. 5G's development. 68. Where does this passage probably come from? A. A storybook. B. A science fiction book. C. A popular science book. D. A research report. E Technology is developing fast and it has become an important part of our life. Then what will the world be like in the future? 3?D food will be both delicious and nutritious(有营养的). We can use 3?D printers to print some basic materials. __①__ And we can go further. Scientists believe that we just need to turn on a printer in the kitchens and then we can enjoy our favourite food whenever we like. __②__ The 5G network will allow many more people to get information. Big companies like China Mobile and China Unicom will start to offer 5G. It is said that 5G promises download speeds 10 to 20 times faster than 4G. For example, we can download a film within just 1 second. But with a 4G network, it takes a few minutes. There will be much bandwidth (带宽) and we can get unlimited (无限的) information. Underwater cities will provide more space. The earth is becoming more and more crowded. We may turn to underwater homes, which will be built as low as 15 kilometers below the sea. And the different temperatures at the different depths (深度) of the sea can be used to provide power for the homes. __③__ For us common people on the earth, the dream of travelling around space will come true. In the coming years, spacecraft will be as popular as buses, trains and planes. We can leave our home and enter space to take an adventure (冒险). And even we will get used to living there. A robot will be a part of life. Robots can do many of the same things as we humans do like driving cars. But they will be used in other areas as well. They will be able to think. They can tell the difference between right and wrong. They can feel sadness or joy.

These banknotes(纸币) have brighter colors and new security features(防伪特征). We've been using banknotes for around 1, 000 years. Back in the Northern Song Dynasty, Chinese people made the world's earliest paper money to replace(代替)metal coins. These banknotes were called jiaozi. Paper money is cheaper to make and easier to carry. These advantages made it more popular than other forms of money. But now, in the digital( 数码的)age, paper money seems to be disappearing for the same reason. China seems to be heading towards becoming a cashless(不用现金的) society. From supermarkets to street stores, people pay by using the WeChat Wallet and Alipay apps on their mobile phones. Sweden is even closer to a future without paper money. Many Swedish banks no longer even have cash on hand. But there are worries about creating cashless societies. Some say it is unfair to the poor and people without much education. It's not easy for them to open bank accounts(账户)or deal with mobile phones. And if all of your money is “digital”, it may not be safe enough. Is paper money going away? Although paper money is used less than electronic payment (电子支付) in some countries, it won't disappear at once in most parts of the world. 73. When was the fifth edition of RMB upgraded?
