第二节 阅读理解 (20分)
A
Everybody has ( http: / / www.21cnjy.com )to buy or sell things sometimes. Even students who are usually not very rich, have to learn something about making purchases (购卖) intelligently (聪明地). If you are considering a major purchase, or any purchase, you should remember several important things.
Study first, and th ( http: / / www.21cnjy.com )en decide what to buy. You can learn a lot just by reading books and advertisements.
Remember that a hig ( http: / / www.21cnjy.com )h quality product will probably last longer and work better, so you’d better pay more attention to the quality of the product. Of course, for a superior (上好的) product you are expected to pay more. An inferior product may not give you the same quality, but the price could be low. A poor quality product could be expensive and a valuable one could be on sale at a greatly reduced price.
Don’t worry. Take yo ( http: / / www.21cnjy.com )ur time. After you decide what product you want to buy, go to many different stores. If you can’t find the product you want, you try to order it directly from the factory or ask the store to order it for you.
Look for a good deal. ( http: / / www.21cnjy.com )If you wait, you may probably find that your product will go on sale and you may be able to save 10, 20, or even 50 percent of the original price.
Finally, before yo ( http: / / www.21cnjy.com )u buy, make sure that the product is guaranteed (保修的). If you find the lowest possible price, you will generally be happy with your purchase and also keep more money in the bank.
1. Which of the following should you care more while shopping
A. The price of the product.
B. The information of the product.
C. The size of the product.
D. The quality of the product.
2. If you want to m ( http: / / www.21cnjy.com )ake a good purchase, which of the following should you NOT do
A. Getting enough information about the product.
B. Taking your friend’s advice all the time.
C. Making sure about the guarantee of the product.
D. Waiting until the proper time.
3. We can infer from the passage that ______.
A. a poor quality product must be cheap
B. a valuable product must be on sale at a high price
C. waiting before shopping probably means saving money
D. you don’t have to ( http: / / www.21cnjy.com ) learn how to make purchases intelligently if you are rich enough
4. The main purpose of the passage is to tell us that how to ______.
A. find the product you want
B. have a good purchase
C. save money
D. buy the product with high quality
B
It seems that gre ( http: / / www.21cnjy.com )at artists and scientists often suffer from mental problems. Both Einstein and Dickens had mental illness. Now scientists have started to look at whether mental illness and genius (天才) are linked.
Dr Adele Juda stud ( http: / / www.21cnjy.com )ied 5,000 creative people in Germany. She found there were more people with mental illness in this group than in the general population. Poets had the highest rate of mental illness, followed by musicians, with lower numbers for painters and architects (建筑师). Other scientists did research which also showed a strong link between mental problems and creativity. But it did nothing to explain it.
Dr Ruth Richards of ( http: / / www.21cnjy.com ) Harvard University made a breakthrough (突破). Instead of studying creative people, she took a group of psychiatric (精神病的) patients and tested them for creativity. The patients got much higher scores than a normal group. Also, the patients’ close relatives were much more creative than the patients and a normal group. This suggests that the key to the link between creativity and mental illness is in our genes.
But according ( http: / / www.21cnjy.com )to Darwinism, harmful genes should be removed. Some scientists believe that evolution (进化) has created a balance, where the madness of a few people leads to the development of the whole human race. Geniuses may be mad, bad or just difficult to understand, but their discoveries have improved the world we live in.
5. ______ have not been mentioned in Dr Adele Juda’s study.
A. Painters B. Musicians
C. Poets D. Scientists
6. According ( http: / / www.21cnjy.com )to the research of Dr Ruth Richards of Harvard University, we can conclude that ______.
A. all the great artists and scientists suffer from mental problems
B. the patients’ clos ( http: / / www.21cnjy.com )e relatives were less creative than the patients
C. psychiatric patients are as creative as the average people
D. it is our genes tha ( http: / / www.21cnjy.com )t determine the link between creativity and mental illness
7. Which of the following is NOT true according to the passage
A. Among the 5,000 cre ( http: / / www.21cnjy.com )ative people in Germany, more people suffer from mental diseases than the general population.
B. There is a strong link between mental problems and creativity.
C. Psychiatric ( http: / / www.21cnjy.com ) patients make greater contributions than common people.
D. Some scientis ( http: / / www.21cnjy.com )ts think the development of the whole human race results from the madness of a few people.
8. What do we learn from the passage
A. Madness is harmful to the whole society.
B. The madness of a few people may be good for us sometimes.
C. All the talented people are mad.
D. Only the people with mental illness have more creativity.

My grandfather worked ( http: / / www.21cnjy.com ) as a carpenter (木匠). On a particular day, he was building some cases for the clothes his church was sending to an orphanage (孤儿院) in Brazil. On his way home, he found his glasses were gone. When he mentally replayed his earlier actions, he realized what had happened. The glasses had slipped out of his pocket and fallen into one of the cases. The Great Depression (大萧条时期) was at its height, and Grandpa had six children. He had spent twenty dollars for those glasses that very morning.
Several months late ( http: / / www.21cnjy.com )r, the director of the orphanage came to visit all the churches that supported him, so he came to my grandfather’s small church in Chicago. He began by thanking the people for their kindness. “But most of all,” he said, “I must thank you for the glasses you sent last year. You see, some people had just come to the orphanage, destroying everything, including my glasses. Along with not being able to see well, I experienced headaches every day. Then your cases arrived. When I removed the covers, I found a pair of glasses lying on top.”
After a pause he ( http: / / www.21cnjy.com )continued, “When I tried on the glasses, it was as though they had been made just for me! I want to thank you for being a part of that!” The people listened, happy for the miraculous glasses. Sitting quietly in the back, with tears streaming down his face, my grandfather, an ordinary carpenter realized his glasses had found a good place to go.
9. We learn from the passage that the writer’s grandfather ______.
A. got his glasses back from the director of the orphanage
B. found that his glasses were at home at last
C. had a heavy burden of supporting his family
D. worked as a carpenter in a school in Chicago
10. From the pas ( http: / / www.21cnjy.com )sage we can infer that the writer’s grandfather was very ______ after hearing what the director of the orphanage said.
A. surprised B. disappointed
C. pitiful D. moved
11. The underlined ( http: / / www.21cnjy.com )word “miraculous” in Paragraph 3 can be replaced by “______”.
A. practical B. magical
C. necessary D. important
12. What would be the best title for the passage
A. The Perfect Mistake.
B. An Ordinary Carpenter.
C. A Careless Old Man.
D. The Cases for the Clothes.

The 400 phone mes ( http: / / www.21cnjy.com )sages said it all. Veterans (老兵) wanted to talk, and Jeff Beers, a military history expert and the son of a retired navy man, was ready to listen. Beers had volunteered for the Veterans History Project, a programme at the Library of Congress devoted to collecting and saving the oral histories of America’s 19 million veterans (老兵).
“Most of them are ( http: / / www.21cnjy.com )shocked that anyone would be interested in their small story,” says Beers. “They ask, ‘Why now ’ But it has to be now, before it’s too late.” The US Department of Veterans Affairs estimates (估计) that 1.847 veterans die each day.
Beers and the other ( http: / / www.21cnjy.com ) volunteers are collecting the I-was-there detail. One of the most moving came from a World War II POW (prisoner of war).
The World Wa ( http: / / www.21cnjy.com )r II generation is made up of most of the 700 histories gathered since the programme began in 2001. But, says director Ellen Lovell, they want to hear from veterans of every war. “I interviewed my brother-in-law, an army surgeon (外科医生) in Vietnam.” She says, “He said he shared things with me that he’s never told anyone.”
13. What do we learn from the passage about the veterans
A. They live a very happy life after the war.
B. They often tell their stories to others.
C. They are highly respected by others.
D. They are becoming fewer and fewer in number.
14. How did the veterans feel when they were interviewed
A. Happy. B. Sad.
C. Surprised. D. Disappointed.
15. What does the underlined word “it” in Paragraph 1 refer to
A. Veterans wanted to talk.
B. Jeff Beers was ready to listen.
C. The veterans had many stories.
D. There were many phone messages.
16. What is Jeff Beers most interested in
A. Historical records of World War II.
B. Stories written by newspaper reporters.
C. Stories most talked about by the public.
D. Veterans’ wartime experiences.

Whatever our diff ( http: / / www.21cnjy.com )erences as human beings are, we all think we’re more like the rest of the animal world than we realize. It is said that we share 40 percent of our genetic (遗传的) structure with the simple worm (蠕虫). But that fact has helped Sir John Sulston win the 2002 Nobel Prize for Medicine. Sir John is the founder of the Sanger Institute in Cambridge, which was set up in 1992 to get further understanding of the human genome (染色体组).
To help them ( http: / / www.21cnjy.com ) do this, they turned to the worm. What the worm told Sir John and his colleagues was that each of the cells in the human body is programmed like a computer. They grow, develop and die according to a set of instructions that are coded (编码) in our genetic make-up.
Many of the disea ( http: / / www.21cnjy.com )ses that humans suffer from happen when these instructions go wrong or are not obeyed (遵守). When the cell refuses to die but carries on growing instead, this leads to cancer. Heart attacks and diseases like AIDS cause more cell deaths than normal, increasing the damage they do to the body. Sir John was the first scientist to prove the existence of programmed cell death.
17. Sir John Sul ( http: / / www.21cnjy.com )ston got a Nobel Prize for Medicine because he has ______.
A. found that human beings are similar to the worm
B. got the fact t ( http: / / www.21cnjy.com )hat we share 40 percent of our genetic structure with the simple worm
C. found the ( http: / / www.21cnjy.com )computer which controls each of the cells in the human body
D. proved that cell death is programmed
18. People might be seriously ill if the cells in their body ______.
A. grow without being instructed
B. die regularly
C. fail to follow people’s instructions
D. develop in the human body
19. The underli ( http: / / www.21cnjy.com )ned word “they” in the last paragraph refers to “______”.
A. cell deaths B. diseases  
C. instructions    D. cells
20. What is the subject discussed in the passage
A. The theory of programmed cell deaths.
B. A great scientist — Sir John Sulston.
C. The programmed human life.
D. Dangerous diseases.

第四节One possible version:
Saturday September 1, 2007 Sunny
Today is the ( http: / / www.21cnjy.com )first day of the new school term. I was asked to help our new foreign teacher, Peter, to get to know about the school life. In the morning, I showed Peter around our school, which impressed him a lot. At noon, I invited him to eat in our school canteen. We talked about the use of Chinese chopsticks. Knowing that he is crazy about playing basketball, I suggested he play with my classmates. During the sports time in the afternoon, Peter’s wonderful skills made him an eye-catching player on the court. I guess he must have had a good time. So did I. It is the first time that I have communicated with a foreigner, which made me more confident in English learning.
