They used to read The Guardian, but changed to electronic (电子的) newspapers many years ago. Frank first reads some news about space: another space flight has returned from Mars. Then they turn to sport news. As they watch the screen, Mary pays for a robot to make coffee for them. Then Frank disappears into another room to join a video meeting with his business partners around the world. Frank is a computer engineer. Mary is still in their bedroom. She picks up the video phone to talk to her assistant (助理). Mary also has a job and she is doing medical research. Both she and Frank used to have office jobs in London, but in 2040 they decided to move to the seaside and work from home. Frank and Mary have one daughter, Louise. She goes to school only one day a week, mainly to play with other students. Classrooms disappeared in 2035 because there was no longer any need for them: the Internet had made it much easier to learn at home. Louise, now thirteen, is studying Chinese at present, which has become a world language as important as English. Louise has many Chinese friends. They share many things online. According to the family doctor, Louise will live to be at least 130. Her wish is to work for a few decades (十年) and then spend her time studying music and painting. (  ) 1.

The relationship between the United States and China is becoming more and more important in the world. This has really influenced the growth of Chinese language learning in U.S. I am Chris from the United States. I am one of the many people who are learning Chinese. I am studying at a Confucius Institute (孔子学院) in New York. There are 10 students in our class. Some are over thirty years old. Some are middle school students. Our teacher comes from Beijing. He is fun and often tells us interesting things in China. I think Chinese is difficult to learn. The biggest challenge for American learners is the writing. Chinese is completely different from any other language in the world. It will take me a lot of time to learn enough Chinese characters(汉字). But I think there are many benefits(益处)of spending time in learning Chinese. One important benefit is that it makes me see things from a different point of view, because Chinese is such a different language from English. I think for American students the most important benefit is that learning a challenging language can open up their eyes. (  ) 1. From the passage we know that　　. A. Chris is an American B.

C If you put your history notes under your pillow and sleep on them the night before an exam, will you do any better in the exam? Most of us have hoped this might help. However, knowledge can’t go through the pillow into your brain. But that doesn’t mean you can’t learn while you are asleep. Scientists aren’t exactly sure how it works, but they have discovered that the brain can learn things during sleeping hours. In one experiment, researchers gave German speakers some Dutch words to learn. Then, they divided them into three groups. The researchers played the Dutch words for people in Group 1while there were asleep, without telling these German speakers what they were doing. The sound was low so it didn’t wake them up, and only the newly introduced words were used. Another group listened to the same words while they were awake. The researchers found the people in Group1 were better able to identify and translate the words later. This was true only for the words that were played while they slept. The third group listened to words when they walked. The walkers didn’t have the same success in remembering the words as the sleeping group. The researchers later found that people had more slow-wave brain activity all over the night. They said that more slow waves made people have a better memory for the new words. (  ) 1. When did the researchers play foreign words for people in Group 1 in the experiment? A. Before they went for a walk. B. Before they went to bed. C. When they were asleep. D. When they were having dinner. (  ) 2. What does the underlined word “identify” mean in Chinese? A.提高 B.辨认出 C.隐藏 D.逃避 (  ) 3. The last two paragraphs tell us the experiment’s ________. A. result B. reason C. influence D. purpose (  ) 4. Which of the following is true? A. Scientists think people can’t learn during sleeping hours. B. German speakers enjoy learning Dutch words. C. Slow-wave brain activity can help people have a good sleep. D. People in Group 3 didn’t remember the words as well as those in Group 1. (  ) 5. Where is the passage most probably from? A. A history textbook. B. A science magazine. C. A travel newspaper. D. A modern novel. ( 1 / 14 ) 学科网（北京）股份有限公司 $
