We Chinese are never afraid of any difficulty.BThere is a story about a famous scientist who had made several very important medical breakthroughs(突破). He was interviewed by a newspaper reporter who asked him why he thought he was able to be so much more creative than the other person. What made him so unique?He replied that, in his opinion, it all came from an experience with his mother that took place when he was about two years old. He was trying to get a bottle of milk from the fridge when he lost the bottle and it fell, with milk all over the kitchen floor---a sea of milk!When his mother came into the kitchen, instead of shouting at him, giving him a lesson, or blaming him, she said, “Robert, what a great and wonderful mess you have made! I have rarely seen such a huge mess of milk. Well, the trouble has already been made. Would you like to get down and play in the milk for a few minutes before we clean it up?”Indeed, he did. After a few minutes, his mother said, “You know, Robert, whenever you make a mess like this, you have to clean it up and put everything in its right order. So, how would you like to do that?”He chose a sponge(海绵)and together they cleaned up the milk.His mother then said, “You know, what we have here is a failed experiment in how to carry a big milk bottle with two little hands. Let’s fill the bottle with water and see if you can discover a way to carry it without dropping it.”The little boy learned that if he took the bottle at the top with both hands, he could carry it without dropping it. This scientist then said that it was at that moment that he knew he didn’t need to be afraid to make mistakes. Instead, he learned that mistakes were just chances for learning something new, which is, after all, what scientific experiments are all about. Even if the experiment “doesn’t work”, we usually learn something valuable from it.Wouldn’t it be great if all parents would do the way Robert’s mother did to him? Wouldn’t it be wonderful if we could all act in a similar manner too? Help someone learn from his/her mistakes.31. Where is the passage probably taken from?A. A scientific report.B. An Advertisement.C. A speech.D. A magazine.32. What does the writer want to tell us in this passage?A. He wants to tell us that we should do experiments.B. He wants to tell us that we should learn from failures.C. He wants to tell us that we should make mistakes.D. He wants to tell us that we should play with our mother.33. What did the mother do when she saw the mess of milk?A. She shouted at the boy.B. She gave the boy a lesson.C. She cleaned it up at once.D. She asked the boy to find out a way to solve the problem.34. The following statements about the scientist are true EXCEPT__________.A. He failed to discover how to carry a milk bottle without dropping it.B. He was a creative person.C. He was not afraid of making mistakes.D. He did a lot of experiments.35. What does “he did” mean in the fourth paragraph?A. He played in the sea of milkB. He made a mess of milk.C. He cleaned the mess up and put everything in its right orderD. He heard what his mother said.CShe was one of my second grade teachers. She taught me maths, but at that time, I thought she was teaching me everything I would need to know about life itself. Yes, Mrs. Pillar was a great teacher. However, I will always be grateful to her for what she did for me more than ten years later.As a college student, I was involved in an “accident” when I walked into a robbery at a store. One of the thieves hurt me in the head. I had to drop out of college to be in hospital for several months. Even after I left the hospital, I had to relearn practically everything, including walking, talking, and yes, maths.To help me with that task, Mrs. Pillar volunteered to come to the hospital and later to my house once a week, to work with me. At first, she presented me very easy maths skills. Then, as time went by, and I made progress, my “homework”became more difficult.I remember very clearly how she would come to my home on Sundays, sit with me at the kitchen table, and throw various coins on the table. She would ask me to show her 38 cents, 17 cents, 63 cents. It was difficult to deal with, but she also made it fun. After a year and a half, I had progressed successfully, both physically and mentally, to return to college. I continued therapy regularly, and four years later I graduated from the University of Texas at the top of my class. Following that, I went on with further study.As the years passed, I always heard from Mrs. Pillar. Unluckily, one day my parents told me that Mrs. Pillar had been in hospital. Now it was my turn to help her. When Iwalked into the ICU at the hospital, Mrs. Pillar was in a hospital bed and could not speak. I thought that the situation was greatly the same. Nothing had changed except for who was in the bed and who was standing beside it.I told Mrs. Pillar that I would be back and that I would work with her just as she had worked with me years earlier. As the days went on, I saw Mrs. Pillar progress each time I visited her. One day, I pulled some coins out of my pocket, dropped them on her bed, and asked her to show me 12 cents. The nurse thought that my action was rather strange until Mrs. Pillar smiled happily as I began working with her---just as she had done with me years before.Mrs. Pillar made wonderful progress and finally left the hospital. One day I called her to wish her a happy New Year. She spoke into the phone quite quickly and confidently, “Happy New Year to you and your family, Michael. Thank you for everything you’ve done for me.”I quickly replied, “Thank you for everything you’ve done for me.”Mrs. Pillar was one of my second grade teachers, but she taught me so much more about life than only mathematics.36. Why was the writer in hospital?A. Because he wanted to be a volunteer.B. Because he wanted to look after others.C. Because he wanted to know about life.D. Because he was hurt in a robbery.37. The underlined phrase “drop out of” may mean “_______________”.A. 落下,掉下B. 降低,减少C. 退学, 休学D. 删除,省略38. Which of the following statements is TRUE according to the passage?A. Mrs. Pillar gave the writer some coins so that he could learn maths well.B. The writer helped Mrs. Pillar the same way as she had done to the writer himself.C. The writer was very grateful to Mrs. Pillar because she donated money to him.D. The writer and Mrs. Pillar were ill in hospital at the same time.39. Which of the following statements is NOT mentioned in the passage?A. Mrs. Pillar was a kind teacher.B. The writer was the top student in the university.C. Mrs. Pillar and the writer used to cook in the kitchen.D. Mrs. Pillar and the writer helped with each other.40. What’s the main idea of the passage?A. Kindness works wonders.B. Better to give than to receive.B. The best way to teach maths. D. Time flies fast.DHave you ever dreamed about a trip to space? Seeds (种子)of some vegetables and crops are a lot luckier than you, as they have travelled to space and back.China is among the three countries in the world that carry out agricultural (农业的)research in space. The others are Russia and the U.S. Since 1987, China has sent about 1000 kinds of seeds into space. These include green peppers, tomatoes, cucumbers, carrots and rice. Even on China’s first manned spacecraft Shenzhou V there were some seeds from Taiwan.“Conditions in outer space such as radiation(辐射)and low gravity can cause big changes in the seeds,” said Chinese researcher Jin Xing.But not all seeds are better after going to space. After returning to the earth, the best seeds are chosen. These seeds produce much more and also grow faster than normal seeds. As the safety of genetically modified(转基因)food is still being talked about, some people are not sure about the safety of these “space vegetables” because some of their genes(基因)are changed during the trip to space.But Jin holds the more hopeful view. He said, “Unlike genetically modified crops, no new genes are introduced to the space vegetables, so they are surely safe.”Space vegetables are better than normal vegetables. For example, space tomatoes stay fresh for twenty days, which is one week longer than normal tomatoes. Another popular space vegetable is the peppers. Space peppers have 20 per cent more vitamin C than normal peppers.Researchers are considering holding a tomato festival. By the time people will be able to enjoy about 30 different kinds of space tomatoes on their dining tables. Following the tomato festival, other space vegetables, such as cucumbers, peppers, eggplants, tomatoes, beans, potatoes and pumpkins, would also go to markets with prices 30 to 50 percent higher than their common ones.So far, the Chinese Academy of Sciences has set up three space vegetable base fields, one of which is in Shenzhen while the others are in Beijing and Jiangsu Province.41. According to the passage, which of the following countries hasn’t carried out agricultural research in space?A. ChinaB. JapanC. RussiaD. The U.S.42. What will happen when seeds of some vegetables and crops are sent to space and carried back?A. Some of their genes are changed.B. They are all better than before going to spaceC. No changes are caused in the seeds.D. They all produce much more and grow faster.43. Why does Jin Xing have no doubt about the safety of the space vegetables?A. Because the seeds sent to space stay the same.B. Because the seeds sent to space are the best.C. Because no new genes are brought into them.D. Because space vegetables are luckier.44. Which of the following statements is TRUE?A. Genetically modified food is completely safe.B. The space vegetables don’t belong to genetically modified food in some ways.C. About 1000 kinds of seeds were sent into space on Shenzhou V.D. Seeds back from space must be planted in special rooms controlled by computers.45. What is the underlined word “cucumber” in the second paragraph?A. A product from Russia.B. A kind of gene. .C. A product from Taiwan.D. A kind of agricultural product.第II 卷(非选择题共51分)四、填空(共16小题;每小题1分,满分16分)A)根据括号中所给的汉语写出单词,使句子意思完整正确。
