    Once upon a time, a young man wanted to go to a village on business. Halfway there was a mountain. Before he left home, his family reminded him of staying calm even in face of beasts(野兽) and just climbing onto trees. So they couldn't do anything to him.
    The young man took the words into his heart and left alone. He walked for a long time carefully and found no beasts were out there. He thought his family's worries were unnecessary. He put his mind at ease and walked happily. At this right moment, he saw a big tiger running to him and he rushed into a tree.
    The tiger roared around the tree. It even jumped to reach the man. The young man, who was supposed to hold the branch tightly, fell off the tree just because of panic and right fell on the back of the tiger. He had to hold the tiger closely, which was scared and started running away at once.
    A passerby didn't figure it out at the sight and said in admiration(羡慕), "How cool the man riding the tiger is! He is like a superman!"
    The man on tiger's back was actually suffering in silence, "It looks like I am like a superman, but you don't understand I am riding a tiger and find it hard to get off. I am in panic and almost scared to death."

    A psychologist walked around a room while teaching stress management to the audience. As she raised a glass of water, everyone expected they’d be asked the “half empty or half full” question. Instead, with a smile on her face, she asked, “How heavy is this glass of water?”
    Different answers are called out from the audience.
    She replied, “The absolute weight doesn’t matter. It depends on how long I hold it. If I hold it for a minute, it’s not a problem. If I hold it for an hour, I’ll have an ache in my arm. If I hold it for a day, my arm will feel numb and paralyzed. In each case, the weight of the glass doesn’t change, but the longer I hold it, the heavier it becomes.”
    She continued. “The stresses and worries in life are like that glass of water. Think about them for a while and nothing happen. Think about them a bit longer and they begin to hurt you. And if you think about them all day long, you will feel paralyzed and be unable to do anything.”
    It’s important to remember to let go of your stresses. As early in the evening as you can, put all your burdens down. Don’t carry them through the evening and into the night. Remember to put the glass down!”

    “I’ve had to deal with people staring at me my whole 19 ,” Jordan, now thirteen, explains.
    20 Jordan sometimes feels uncomfortable when people stare, she’s proud to be different. And she’s using her difference to 21 other kids with disabilities.
    “You can do cool things---just give it a try,” Jordan says.”You might have to do it 22 than other people, but it’s worth trying.”
    Each year, about 2,000 babies in the United States are born with limb differences, like Jordan was. That means they are 23 all or part of an arm or a leg. Doctors aren’t sure 24 this happens.
    With only one hand, Jordan can have a hard time doing certain activities, 25 tying her shoes. She sometimes uses a prosthetic arm(假肢)to help her do things like riding her bike.
    Growing up, Jordan attended camps for kids with limb differences. Then in 2015,she was invited to 26 a new prosthetic arm---one that would turn her disability into a “superpower”. Jordan teamed up with designers and 27 used a 3-D printer to create the prosthetic arm. Instead of paper, the 3-D printer used plastic to create the arm. Jordan called her invention Project Unicorn. Jordan’s mom 28 the story of Project Unicorn online, and it quickly spread on social media. Jordan helped other kids with disabilities.
    In 2017, Jordan and her mom started an organization 29 Born Just Right to help other kids with limb differences. They’re making it 30 for kids from across the US to create their own limbs, like Jordan did.

    At the age of 16, Einstein always played with a group of mischievous (顽皮捣蛋的) kids. Because he was so busy playing, he didn’t study enough and failed his final exam.
    One morning, when Einstein was holding a fishing rod and was about to go fishing with his friends, his father stopped him and said calmly, “Einstein, you’re so fond of playing all day that you failed your exam.? I’m worried about your future.”
    “What are you worrying about? Jack and Robert also failed, but don’t they still get to go fishing??”
    “My boy, you can’t think like that,” his dad said. “There is a story that people tell in our hometown. Listen to it now.”
    “There were two cats playing on a roof. One cat got caught off guard and fell down the chimney (烟囱) while holding the other cat. When the two cats climbed out of the chimney, one of the cats had soot on his face, while the other cat’s face was clean. Seeing the soot-faced cat, the clean cat thought its face must be dirty, so it quickly ran to the riverside and washed its face. The soot-faced cat saw the clean-faced cat and thought its face was also clean, so it just swaggered down the street.”
    “Einstein, no one can be your ‘mirror’. You have to think for yourself. If you take your cues from (模仿) others, you will never learn.”
    Hearing this, Einstein laid down his fishing rod and returned to his room. He decided to pay more attention to his studies and less attention to what his friends were doing. This allowed him to be successful.
    34. What was Einstein’s main problem, according to his father?
    A. He was not good at math. B. He liked to fish too much.
    C. He played with mischievous kids too much. D. He failed his exams.
    35. Which of the statements is TRUE according to the story?
    A. The soot-faced cat fell into the chimney first.
    B. The soot-faced cat washed its face clean.
    C. The clean cat didn’t wash its face.
    D. Both cats made the wrong decision.
    36. What does the underlined word “swaggered” show?
    A. The cat ran very quickly. B. The cat felt very confident.
    C. The cat felt he was a fool. D. The cat laughed at the other cat.
    37. What lesson did Einstein learn from his father?

    When I first arrived in China, some of the first Chinese vocabulary I learned had to do with food. I learned the names of a few dishes, but still didn’t know most of the items I saw on Chinese restaurant menus. Fortunately, there were pictures to help me decide.
    Nearly every restaurant menu in China has pictures of food in it. But many restaurants I’ve been to in the US don’t. What is the reason for the difference?
    One thing I’ve surely noticed about China is that food is a bigger part of their culture than it is in the US. A common way to greet someone in China is to ask them if they’ve eaten yet. My Chinese friends post pictures of their meals online way more often than my US friends.
    Food is just a bigger deal here - and having pictures of food in menus is part of that. Some menus are almost like works of art, with lively and well-framed photos.
    Another factor is the names of the dishes. Chinese dishes sometimes have imaginative names like “palace guard chicken” or “three fresh things from the soil”. These are interesting names, but they don’t really tell you what the dishes are like. Therefore, it’s helpful to have pictures so you can actually see what you’re going to be eating.
    There’s probably even more to it than that. All I know is that I was very grateful to have those picture menus when I first came here all those years ago.
