There may be a slight chill (寒冷) in the air, with temperatures staying around 15℃ in March, but Spain's handsome capital is slowly starting to warm up. Even more attractive are the cultural events. A new exhibition on the living and working spaces of Spain's greatest artist, Picasso, has just opened in the studio at the Fundaci髇 Mapfre at Paseo de Recoletos 23 . It runs until 11 May with rarely seen pieces borrowed from his family. Later this summer, the anniversary of the death of the Renaissance (文艺复兴) painter El Greco will be marked with an exciting exhibition at the Museo del Prado at Paseo del Prado from 24 June to 5 October. How to go? The widest range of flights is offered by EasyJet — from Bristol, Edinburgh, Gatwick, Liverpool and Luton. British Airways and its sister airline Iberia combine forces from Heathrow and London City. Ryanair flies from Manchester and Stansted; Air Europa flies from Gatwick. Barajas Airport is 12km north璭ast of the city centre and is served by frequent trains on Metro line 8, but the shortest underground journey is a bit complex with at least one change at Nuevos Ministerios station and takes about 30 minutes. The fare to any station in the city centre is 4.50. The airport express bus runs every 15 to 35 minutes around the clock; 5 one way. It takes 40 minutes to reach the city centre. A taxi takes half the time. A flat rate of 30 covers most of central Madrid. 21.When will the exhibition about Picasso close? A.On 23 March. B.On 5 October. C.On 24 June. D.On 11 May. 22.Which airline operates flights from Manchester to Madrid? A.EasyJet. B.British Airways. C.Air Europa. D.Ryanair. 23.What is the fastest way to reach central Madrid from Barajas Airport? A.Take a city bus. B.Take a taxi. C.Take Metro line 8. D.Take the airport express bus. B My school appeared on the news last week because we had made an important change in our local area. Our class had planted a large garden in what was once only a vacant lot. It was a lot of work but it was all worth it. I got blisters (水疱) from digging, and we all got insect bites, too. I learned a lot about gardening and collaboration (合作), and then I learned about the media. Our teacher telephoned the TV station and informed them of what we had accomplished. She spoke with the producer. The producer checked with the directors, but they said there were plenty of stories similar to ours. They wanted to know what was special about our particular garden, since many schools plant them. The teacher explained that, after going on the Internet to learn about the prairie (大草原), we had made a prairie garden. We had been to a prairie and gotten seeds from the plants, and then we planted them. We did not water the garden, but we did weed it. We decided to let nature water it with rain, since that was how prairies grew in the past. We sent a picture of the garden to the news station. In the picture, the grass was so high that it stood taller than the fourth grade students. As a result, the producer sent a reporter to our school. The reporter interviewed the headmaster and asked him many questions about the garden. After that, he interviewed us, and we explained to him what we had learned through this project. That night, we watched the news, and there we were. The news reporter told our story. It was only two minutes long, but it was us. We were famous. All that work, all those blisters, it was worth it. We knew that when we saw the garden every day, but now we knew that the whole city thought so, too. 24.What seemed to be the TV directors' initial reaction to the garden? A.They were excited. B.They were surprised. C.They were uninterested. D.They were worried. 25.What is special about the garden? A.The seeds came from the plants of a prairie. B.The grass grew faster than common grass. C.Weeds were allowed to spread naturally. D.Underground water was used for the plants. 26.What does the underlined word “that” refer to in the last paragraph? A.We got blisters on our hands. B.The garden would be famous. C.Our hard work was worthwhile. D.The project would be finished. 27.How did the author feel about the project? A.Annoyed. B.Proud. C.Cocky. D.Arrogant. C Heads up! Across the country, sports injuries are a safety concern for young athletes. Now, the American Medical Association (AMA) has a new set of guidelines aimed at protecting players from the danger of concussions (脑震荡) - serious injuries caused by a blow to the head. “By raising awareness of the serious risks associated with concussions and ensuring that the appropriate guidelines are in place, we can reduce the number of young athletes who may return to the game too soon, which can put their health at further risk,” said AMA Board Member Jack Resneck, Jr., M. D., in a statement. The policy recommends that young athletes who may have a concussion be taken off the field as soon as possible. Then, they are only to return to their sport with a doctor's written approval. The policy also sets age璼pecific rules for health care professionals and athletic organizations in evaluating and caring for concussions. According to the Centers for Disease Control and Prevention (CDC), a concussion is a type of traumatic (创伤的) brain injury caused by a bump, blow, or jolt to the head or hit to the body that causes the head and brain to move rapidly back and forth. This type of movement can cause the brain to bounce around or twist inside the skull (颅骨). It can damage brain cells and create chemical changes in the brain. The CDC says that between 1.6 million and 3.8 million traumatic brain injuries caused by sports and recreation?related activities occur in the U.S. every year. A study from the Center for Injury Research and Policy showed that as many as 40% of high school athletes return to playing before they should. The AMA's new guidelines should help to bring those numbers down. 28.Why does the AMA set the new guidelines? A.To protect athletes from concussions. B.To raise safety standards of sports. C.To set rules for health care evaluation. D.To help players return to the game quickly. 29.What should young athletes who may have a concussion do? A.Avoid using the head. B.Get treatment in time. C.Leave the field forever. D.Switch to another sport. 30.What is paragraph 4 mainly about? A.How the CDC works. B.What causes damage to brain cells. C.What a concussion is. D.How a concussion can be prevented. 31.Which of the following is the best title for the text? A.Sports Injuries in the U.S. B.Rules for Safer Play C.Advice to Athletes D.New Policies for Doctors D Organic food is very popular. It is also expensive. Some organic food costs twice as much as non璷rganic food, but new parents and pet owners are willing to pay up to 200% more for organic food. However, there are people who think it is a waste of money. There is one main difference between organic and non璷rganic food. Organic farms do not use agricultural chemicals, such as pesticides (杀虫剂). In many countries organic foods have special labels. These guarantee that the products are natural. Some people think organic means locally grown. Originally this was true. Over time organic farming became more difficult. The demand for organic food grew larger than the supply. Small companies had to sell out to large companies. There weren't enough organic ingredients (原料), such as grain and cattle. This made it difficult for many organic companies to stay in business. Today, many large companies have an organic line of products. Is organic food more nutritious? This is part of the debate. Many farmers and consumers believe it is. They think agricultural chemicals cause health problems such as cancer. Many health professionals disagree. Few studies prove that organic foods prevent health problems. Health specialists worry more about bacteria (细菌), such as E. coli and salmonella. These can get into contact with organic and non?organic food. Doctors recommend washing produce very carefully. Handling meat carefully is important too. Most people agree that naturally grown food tastes better. Is tastier food worth the extra money? This is a matter of opinion. Whether it is healthier or not may require more research. However, organic consumers argue it is better to be safe than sorry. 32.What is probably the major concern of organic food consumers? A.Price. B.Variety. C.Freshness. D.Safety. 33.What is the doctors' suggestion? A.Make sure the food is clean. B.Reduce the use of pesticides. C.Grow your own food. D.Buy large companies' products. 34.Which of the following do most people agree on organic food? A.It is easier to grow. B.It tastes better. C.It contains more fat. D.It is more nutritious. 35.Where does this text probably come from? A.A recipe book. B.A health magazine. C.A medical report. D.A chemistry paper. 七选五 (每小题2分 共10分) 根据短文内容,从短文后的选项中选出可以填入空白处的最佳选项。选项中有两项为多余选项。 The Hotel Wake ?up Call Gets Personal Here's a wake?up call: The hotel front desk will do one better than ringing your phone in the morning. They'll send an actual human being to your room. Don't worry. They won't come in and give you a good morning kiss. __36__ Never mind that most travelers nowadays have smart phones with built璱n alarm clocks. __37__ Here are some examples. At Wolcott Hotel, if a wake璾p call is unanswered, they will send an employee to your door. At Las Ventanas al Paraiso, an employee shows up at your room to wake you up with tea, coffee and breakfast bread. At Mandarin Oriental, a person rather than an automated system will call to wake you up. __38__ Hotels have always taken the wake?up call seriously. __39__ If you don't get your call within five minutes of the requested time, you won't have to pay for your room. Travelers, too, still want to have an option of a wake?up call. A study of 285 guests at Crowne Plaza found that 53% considered a wake?up call very important. __40__ In the late 1980s, hotels turned to automated systems. Then all you'd get was a ring and silence. In the ever?competitive race for loyal customers, however, many hotels are now getting creative with the wake?up call. Some hotels even have recordings of celebrity voices. And more hotels will go back to the old in?person system of wake?up calls. A.But they might bring you coffee. B.If you don't answer, you'll get a wake?up knock. C.The human wake?up call is a way to personalize a guest's stay. D.The hotel gets 15 to 30 requests for wake?up calls each day. E.Crowne Plaza, for instance, has a wake?up call guarantee. F.But the wake?up call became less personal over the years. G.Some guests sleep through the call, while others turn their phone ringers off. 第三部分 语言运用(共两节,满分30分) 第一节 完形填空 (共20小题;每小题1.5分,满分30分) 阅读下面短文,从短文后各题所给的A、B、C、D四个选项中选出可以填入空白处的最佳选项。 Our apartment has been hit by a "hurricane".

新冠肺炎疫情给我国经济带来较大冲击。2020年3月以来,国内疫情防控形势趋稳向好,某市政府决定向全体市民或特定群体发放消费券。消费者在消费券有效期内去指定的商品和服务机构消费时可用其抵扣一定金额,由财政向商品和服务机构补偿支付这部分费用。 专项消费券仅限在住宿餐饮、文体旅游等生活服务业的线下实体店使用,消费满100元补50元、满200元补100元;购买智能终端(含5G手机)、智能家电、智能家居等产品,单笔订单满2000元可使用智能产品消费券,单张消费券补贴最高限额400元;红利性消费券面向城乡低保、特困和低收入家庭等困难群体发放,不设消费门槛,每人500元。截至2020年6月,该市累计兑付财政补贴6.5亿元,撬动市场消费73.4亿元。 结合材料,运用经济生活知识,完成下列任务: (1)相比于直接发放现金,发放消费券有哪些优点?(6分) (2)说明该市三种消费券设计的合理性。(9分) 17.(9分) 老旧小区改造是党中央、国务院高度关注的重大民生工程。某社区充分发挥协商议事优势,有效破解老旧小区改造难题。 改造前期,该社区党支部召开5场专题座谈会,组织党员入户走访,主动解读政策,征集群众诉求,确定改造项目14个。对于“停车位和绿化如何兼顾?”“加装电梯如何协调不同楼层住户利益?”等居民意见分歧大的关键问题,社区党支部和居委会邀请街道办、区住建局、居民代表、设计和施工单位等召开协商恳谈会,协商成果向全体居民公示。改造过程中,社区党委和居委会鼓励各楼栋成立自治小组,开展内部协商,评议改造项目,完善建设方案。在广泛协商的基础。上,老旧小区焕发新面貌。 结合该社区推进老旧小区改造的实践,分析协商民主在社区治理中的重要意义。(9分) 18.(8分) 榫卯是古代中国建筑、家具及其他木制器械的主要构成方式。榫卯结构,其不用一钉一铆,一凹一凸之间即可将构件稳固连接。早在7000年前,浙江余姚河姆渡文化的原始居民建筑中便运用了多种形制的榫卯结构。在钢筋水泥密布的现代生活中,榫卯工艺已经淡出了人们的视野。 精巧别致的微缩版世博会中国馆、美观实用的“鲁班凳”、结实环保的木拱桥……近来,木工匠人“阿木爷爷”的木工视频在海内外圈粉数百万,收获上亿播放量。通过他的短视频,更多人见识了中国传统木匠精湛的技艺,以及蕴藏在榫卯结构中的“天人合一”“和谐”等古老文化和智慧。 有人认为,传统榫卯工艺因现代传媒的广泛传播而具有价值。运用文化生活知识并结合材料,对此观点加以评析。(8分) 19.(6分) 为保护长江渔业资源和生物多样性,2020年1月1日起,长江流域迎来“十年禁渔”。目前,“禁渔令”实施已过半年,但长江偷捕鱼类现象并未禁绝。 没有买卖就没有杀害,问题的关键在需求端。“禁渔令”推高了鱼类的价格,在暴利的驱使下,对“江鲜”的捕捞、运输、销售已经形成完整的黑色地下产业链。此外,一线执法队伍人手与装备不足,如长江江苏段400多公里,有渔业执法资格证的只有217人,长期在一线工作的约100人。“禁渔令”涉及约11.3万艘合法持证渔船、近30万渔民,社保、补偿、就业培训的力度不够,导致上岸渔民面临返贫的威胁,其结果就是一部分渔民转入非法捕捞,造成更坏的影响。 结合材料,运用系统优化的知识,说明长江“十年禁渔”怎样才能取得实实在在的效果。(6分) 20.(17分) 生态文明建设是关系中华民族永续发展的根本大计。建设美丽家园,是人类共同的梦想。 ◆绿水青山就是金山银山 2005年8月,时任浙江省委书记的习近平来到余村调研,高度评价余村下定决心关闭矿区、全面走绿色发展之路的做法,并首次提出“绿水青山就是金山银山”的重要理念。 2020年3月,习近平总书记再次来到余村考察,了解该村多年来践行“绿水青山就是金山银山”理念、推动绿色发展发生的巨大变化。他对村民说,余村现在已经在全国起到示范作用,要再接再厉,顺势而为,乘胜前进,芝麻开花节节高。 15年来,“绿水青山就是金山银山”的重要理念已经逐渐成为全党全社会的一致共识和自觉行动,为美丽中国建设提供了价值指引与基本遵循。 (1)结合材料,运用社会意识的知识,说明“绿水青山就是金山银山”的理念为什么会历久弥新。(8分) ◆中国对全球生态环境治理的贡献 中国对全球生态文明建设的贡献,是行动和成绩的贡献。从推动《巴黎协定》生效实施到设立气候变化南南合作基金,从发起建立“一带一路”绿色发展国际联盟到将绿色发展合作计划纳入中非“八大行动”,中国同世界各国形成了多层次、多渠道、多领域的合作局面。面对生态保护和经济发展的考题,中国以身作则进行节能减排、转型升级,在阵痛中前行;面对以邻为壑的零和博弈思维,中国主张“已所不欲,勿施于人”“美美与共,天下大同”,通过政策对话、人员培训、平台搭建等多种方式积极参与国际环境事务。 中国对全球生态文明建设的贡献,是理念和经验的贡献。共享单车、光盘行动等绿色环保的生活方式,库布其、三江源等生态样本的成功经验,生态补偿、环保督察等构成的生态文明制度体系,“绿水青山就是金山银山”“山水林田湖草是生命共同体”等绿色发展的价值理念……中国向世界全方位展示了推动绿色发展的中国方案。 (2)综合运用所学知识,围绕“中国对全球生态环境治理的贡献”这一主题写一篇短文。(9分) 要求:观点明确,紧扣主题;可以就某一点深入分析,也可以综合论述;学科术语使用规范;论述合乎逻辑,条理清晰;250字左右。 - 2 -

She composed much of her first work, Harry Potter and The Sorcerer's Stone in a poor situation, often planning out her chapters in cafes near her small apartment in Edinburgh. Previous to Rowling penning the Harry Potter books, her life was full of struggle and loss. Her mother died in 1990 because of a disease. Her first marriage, to Jorje Arrantes in 1992, ended just over a year later. Unable to find work, Rowling struggled to support herself and her daughter on State Aid assistance. Her financial circumstances would not change until the late 1990s, when the Harry Potter series went beyond all expectations for success. Aided by the Scottish Arts Council, Rowling was able to complete her first novel, but initial encouragement from publishers was actually non-existent. She was told to find a day job, and the UK publisher, Bloomsbury, firstly published only 1000 copies of the novel, titled in the UK as Harry Potter and The Philosopher's Stone. Within a half year of its publication in 1997, the novel achieved its first award, the Nestle Smarties Book Prize. A few months, later, it received the British Book Award for Best Children's Book of The Year. By 1998, Scholastic purchased publication rights, and Rowling, now on her third part of the series, was enjoying great success. The popularity of the series has made Rowling the most popular children's author ever. The interest in the books from both adults and children aroused the enthusiastic reading among younger children eager for the next part of Harry's adventures. Queen Elizabeth II honored Rowling in 2000, titling her as an Officer of the British Empire. She remarried in 2001, to Dr. Neil Murray, with whom she has two children, David and Mackenzie. In her public life, she devotes time to causes dear to her, including relieving world poverty, and funding research towards medicine. 24. How did Rowling make a living in the early 1990s? A. By finding a day job. B. By writing some stories. C. By receiving government support. D. By working for cafes near her house. 25. Who contributed a lot to Rowling's first novel? A. The publishers. B. Rowling's daughter. C. Rowling's former husband. D. The Scottish Arts Council. 26. What can we infer from the last paragraph? A. Rowling is working in the British Empire. B. Rowling has done much for charity. C. Rowling doesn't get on well with Neil. D. Rowling spends much time with her family. 27. What can be a suitable title for the text? A. J. K. Rowling B. Harry Potter C. J. K. Rowling's Hard Life D. The Publish of Harry Potter C Human activities are killing wildlife at an alarming rate, with causes ranging from environmental pollution to the built environment. For bird species, nighttime collisions(碰撞)with power lines are driving significant population decline. But now scientists have come up with a clever way to make the lines easier for birds to spot, without being ugly to humans. Industry and U. S. Fish & Wildlife Service guidelines recommended that electricity companies mark their power lines with plastic attachments to make it more visible, but birds were still dying. Biologists reported that 300 Sandhill cranes(鹤)perished in one month in 2019 from collisions with marked lines at the Rowe Sanctuary 'in Nebraska, where the cranes stopped over during their annual spring migration. "We need forward-thinking methods to protect not only large birds that are naturally at greater risk from power lines but also millions of smaller birds," said Anne Lacy of the, International Crane Foundation. Bird species can see ultraviolet light(紫外线)at night. So James Dwyer, a wildlife biologist at a consulting firm, EDM, had the idea of using near-visible UV light to brighten power lines. EDM's engineering team and the Dawson Public Power District developed such light systems and installed them on a tower supporting a power line at Rowe Sanctuary. Over a 38-night period, crane collisions decreased by 98 percent when the lights were on, the researchers reported in a study published online in May in Ornithological Applications. Richard Loughery, director of environmental activities at the Edison Electric Institute, who was not involved in the project, says the new UV system adds an important tool for use in hotspots where endangered bird species nest and feed. "I don't want electricity companies to build lines wherever they want because there's a new tool," says biologist Robert Harms of the U. S. Fish &. Wildlife Service, who was not involved in the work. But for existing lines, he says, the UV system could be absolutely amazing. 28. Why was the first method abandoned to protect birds? A. It couldn't protect birds migration. B. It couldn't prevent birds from standing on the plastic attachment. C. The used material was hard for birds to spot at night. D. The used material made more birds come to the power line. 29. What does the underlined word "perished" in paragraph 2 mean? A. Died. B. Appeared. C. Survived. D. Increased. 30. What was the main reason for choosing UV light to protect birds? A. It was more economical. B. It was not harmful to birds. C. It was invisible to people but not to birds at night. D. It was a new technology tool for protecting birds. 31. What did Robert Harms think of the UV system? A. Unnecessary. B. Satisfactory. C. Critical. D. Skeptical. D Over 40 years ago, Walter Mischel, a psychologist, explored self-control in children with a simple but effective test. His test using the "marshmallow(棉花糖)test" laid the groundwork for the modern study of self-control. Mischel and his colleagues presented a preschooler with a plate of treats such as marshmallows. The child was then told that the researcher had to leave the room for a few minutes, and if the child waited until the researcher returned, she could have two marshmallows. If not, she would be allowed to eat only one marshmallow. In children as well as adults, willpower can be thought of as a basic ability to delay gratification(满足). Preschoolers with good self-control sacrifice the immediate pleasure of a marshmallow in order to enjoy two more at some later point. The marshmallow test eventually led Mischel and his colleagues to develop a framework to explain our ability to delay 'gratification. He proposed what he called a "hot-and-cool" system to explain why willpower succeeds or fails. The cool system is essentially a thinking system, reminding yourself, for instance, why you shouldn't eat the marshmallow. The hot system, however, is emotional. It is responsible for quick responses to certain triggers(诱因)-such as eating the marshmallow without thinking of the long-term benefits. When Mischel revisited his marshmallow-test subjects as adolescents, he found that teenagers who had waited longer for the marshmallows as preschoolers were more likely to achieve high grades, exhibit self-control in frustrating situations and concentrate. However, the marshmallow study didn't end there. Recently, another group of researchers tracked down 59 subjects, now in their 40s, who had participated in the marshmallow experiments as children. The researchers tested the subjects' willpower strength with a laboratory task known to show self-control in adults. Much to their surprise, the subjects' willpower differences had largely remained over four decades. Research has yet to fully explain why some people are more sensitive to emotional triggers, and whether these patterns might be corrected. However, the recent findings offer a future biological research direction for the push and pull of "marshmallow". 32. What can we know about Mischel's test? A. It provided a basis for the study of self-control. B. It was interesting for kids. C. It was effective to adults. D. It was applied to primary school students. 33. What is paragraph 4 mainly about? A. The relationship between two systems. B. An explanation for the research results. C. The benefits of delay gratification. D. A framework to generate delay gratification. 34. How did the second group of researchers feel about the outcome of their test? A. It's encouraging. B. It's doubtful. C. It's exciting. D. It's unexpected. 35. What can we learn from the last paragraph? A. Researchers have grasped different patterns of willpower. B. People should try hard to have willpower. C. More research into willpower needs to be done. D. It's hard to describe the sensitivity to emotional triggers. 第二节(共5小题;每小题2分,满分10分) 根据短文内容,从短文后的选项中选出能填入空白处的最佳选项。选项中有两项为多余选项。 Zongzi is a traditional food for celebrating Duanwu Festival(Dragon Boat Festival). Zongzi is a popular dish served around this festival. Dragon Boat Racing isn't a must in the North-west of China. 36 Zongzi is basically glutinous rice(糯米) with different fillings wrapped in bamboo leaves. After being cooked, all the ingredients stick together and stay in a particular shape when unwrapped. 37 But it's worth every bit of effort. 38 It was very difficult for young children and most of the time we ended up with broken leaves and spilt rice. But my parents always acknowledged our effort and encouraged us to try again and again. We often didn't have that patience to wrap a Zongzi well, but we did get lots of fun. Thanks to my mum and dad who always involved me in the kitchen, I had many sweet childhood memories about Zongzi. There is a large variety of Zongzi across China. 39 Growing up with sweet Zongzi filled with red beans, I experienced culture shock the first time I heard of salty ones. Having meat as the main filling is very popular in the southern regions of China, such as Shanghai. I have great pleasure in making these Zongzi. The strong aroma(香味)that stays in my kitchen for hours brings me back to those good old days. 40 A. Zongzi is so nice and delicious! B. They differ in size, shape and filling. C. I remember being given the opportunity to wrap Zongzi. D. It's delicious food that involves some specific preparation. E. This experience reminds me where I come from and what is important in life.

Here's why After New York's Met recently announced its change to entrance fees, 56 (make) the $ 25 charge required rather than. 57 (suggest)-it has raised the question whether museums should be free of charge to the public. Ideally, the answer would be YES. However, it's impractical. With funding decreasing every year, museums are struggling to keep their exhibits running. 58 (current), the national museums in London remain free. While it's wonderful for people 59 want to see what these museums offer and teach them, it's not always the best for the museums facing increasing hardships in terms 60 funding. In 2017, a survey 61 (conduct)to find out how funding cuts affected museums. The survey stated that "many publicly-funded museums are facing a funding crisis." I 62 (go) on to say that almost half of all museums reported 63 annual increase in visitor numbers. The reduction in funding also affects staff numbers. Across national museums, there has been a 55% decrease in staff members. How are our national museums supposed to function without enough experienced staff members? Though making entrance fees compulsory will make museums less 64 (access) to some, many museums do have certain days of the week when 65 (admit) is free. Therefore, small and reasonable entrance fees will take pressure off museums that are losing out on funding and staff members. 第四部分 写作(共两节,满分40分) 第一节(满分15分) 刚上高三的你,准备参加学校组织的英语演讲比赛。请以“我的梦想”为题,写一篇演讲稿参赛,内容包括: 1.梦想的具体内容; 2.实现梦想的计划。 注意: 1.写作词数应为80左右; 2.请按如下格式在答题卡的相应位置作答。 My Dream 第二节(满分25分) 阅读下面材料,根据其内容和所给段落开头语续写两段,使之构成一篇完整的短文。 My husband Fred and I moved to a new place. We bought a small house in a reasonably good neighborhood close to Fred's office. It was a one-and-a-half-floor brick house built for soldiers returning from World War II. That house impressed nobody except me. We had to decorate it first because it was so old. Fred and I started to paint the walls and the doors. I also worked outside the house, helping Fred break the ugly fence between us and the neighbors and grow some flowers. After I finished painting walls in the bedroom upstairs, I brought up some water and old towels to wash the window. I washed the inside, then opened the window and stepped out on the kitchen roof to wash the outside. The window was the kind that you couldn't open from the outside. I was so devoted to my housework that I didn't realize the window gradually closed. After finishing cleaning, I stood back to admire the clean glass. And then, I tried to open the window, but I failed. Standing on my kitchen roof, I looked around the neighborhood. That was a lovely afternoon. Where were the neighbor kids riding their bikes? They often rode back from the park. No young voices shouted to one another. The neighbor on the left was at work. Carroll and Julie, an elderly couple, lived in the house at the corner and were our nextdoor neighbors. They were likely to be at home, but our kitchen was on the wrong side of our house for me to call them. I sat down and thought about my situation. Even if someone came along, he couldn't walk in the house and open the window. The doors were locked. That was my husband's doing. "When you're working on an indoor project, anyone could just open the door and come in. So, just keep the doors closed," he would say. I just needed a rope to get down. I sat there, thinking how stupid I was and wishing a rope would magically appear. 注意: 1.续写词数应为150左右; 2.请按如下格式在答题卡的相应位置作答。 Suddenly, I heard a little boy laughing.
