Maybe Le Ying finally became a famous boxer.27. From the passage, we can learn that _______.A. We should make more friends with peopleB. We should face our difficulties bravely and never give upC. We should run away from our difficultiesCAs students, you pass your schoolwork throughdifferent hands from your group leaders to the classrepresentatives(课代表) and finally to the teachers. It mightnot sound too difficult, but sometimes it can go wrong andtake a lot of time.To deal with this problem, Zhang Xirui from Shenzhen Middle School in Guangdong came up with a useful tool, a smart homework collection robot. He won the first prize in the 20th Guangdong Provincial Children’s Invention Awards.The robot is the second-generation(第二代) model made by Zhang. It uses radio frequency identification (RFID, 射频识别) technology, a reader and a special tag that can share information without touching each other. Each student’s notebook has a special RFID tag with their name and the subject. Students only need to place their notebooks on the robot and the machine “sees” the notebook, reads its tag and takes it out of the name list. “Teachers can check who hasn’t handed in homework by connecting their phones with the robot through Wi-Fi,” the 13-year-old explained to Shenzhen Satellite TV.Now, he’s planning to develop a third-generation and hopes to use ultra-high-frequency(超高频) radio technology to read lots of RFID tags from far away. That means if you stick a special tag on your notebook, the robot can read the information from a lot of notebooks at once. Zhang believes this is the key to how AI can make life easier for us.Zhang dreams of becoming a scientist when he grows up. “I’m trying making model airplanes and other scientific and creative projects. Inventing has brought me happiness,” he said.28. What can the second-generation model of smart homework collection robot do?A. It can share information by touching each other.B. It can read lots of RFID tags from far away.C. It can help teachers check who hasn’t handed in homework.29. The underlined word “develop” most probably means _______.A. 研发B. 发现C. 激发30.

Zhang invented a smart homework collection robot.31. Where can you probably find the passage?A. In a health magazine.B. In a travel book.C. In a science book.第二节(共4小题；每小题2分，满分8分)阅读下面短文内容，从短文后的选项中选出能填入空白处的最佳选项。

They will buy some sports things in the store.CIt was break time at the village school. After the bell rang, the children ran out into the sunshine playing with fun and laughter.All but poor Davy. He came out last and very slowly, but he was not laughing. He was thinking of the bad words that his classmates said about his old clothes. Poor Davy had no father, and his mother had to work hard to keep him at school.That night, he went home by the path(小路) that went across the fields(田野). He still felt sad. Just then his teacher came along. She saw who it was, and stopped, saying kindly, “What is the matter, Davy?”He did not speak, but tears(眼泪) began to start. Then he told her all his trouble.When his story ended, she said, “I have a plan, Davy, that I think will help you. How would you like to be a little flower merchant?”“And make money?” said Davy. “That would be exciting. But where shall I get my flowers?” “Right in the fields,” said his teacher. “Pick and bring them all to my house, and I will help you arrange them to make them more beautiful.”So, day after day, Davy looked for beautiful flowers in the fields. He soon made enough money to buy new clothes.6. Why was Davy feeling sad after class?A. Because he couldn’t run as fast as his classmates.B. Because his classmates laughed at his old clothes.C.

If you often experience this, you may have face blindness(脸盲).A new study showed that face blindness might be more common than we thought. One in 33 people (3.08 percent) may have it. Some have serious problems. They cannot even recognize friends or families. But some just have smaller problems. They spend a long time rememberingfaces. People could be born with face blindness, or develop(患...病) it if they hurt their brain.Face blindness sounds like just a small problem. But according to Joseph DeGutis, the writer of the study, people with it may have a bad social(社交的) life. “Recognizing someone is a social signal(信号). It means ‘you are important to me’.” DeGutis told Harvard Medicine News. Not recognizing others may lead to misunderstanding and then fewer friends. Worry about recognizing faces may also make people stay away from social life.In the past, people paid little attention to this. The studies on face blindness only began in the 1990s. Today more scientists and organizations are working to tell more people about face blindness and its effects(影响) on our social life.11. What does the new study tell us about face blindness?A. It may happen to about 3 percent of people.B. It causes more serious problems than we thought.C. It makes most people forget their families faces.12. What does “recognize friends or families” in Paragraph 2 mean?A. get along with friends or families.B. talk face-to-face with friends or families.C. pick out the faces of friends or families.13. According to Joseph DeGutis, how might other people feel when you can’t remember theirfaces?A. They might think it is just a small problem.B. They might think you don’t care about them.C. They might want to know more about face blindness.14. According to Paragraph 3, what might people with face blindness do?A. Study other people’s social life.B. Pay more attention to their looks.C. Stop taking part in social activities.15. What might the writer go on to write about in the fifth paragraph?A. Why some people have face blindness.B. How people with face blindness help each other.C. What scientists and organizations are doing to help people know more about face blindness.第二节(共5小题；每小题2分，满分10分)阅读下面短文内容，从短文后的选项中选出能填入空白处的最佳选项。
