III. Reading Comprehension (30 points, 2 points for each item)
Passage One
Questions 21 to 25 are based on the following passage.
Can your cellular phone really give you cancer? The best answer science can offer so far is maybe.
Researchers have discovered that cellular--phone radiation(辐射) can cause subtle, short-term biological effects in humans-including changes in brainwave patterns during sleep—but their full significance remains to be determined. Given that uncertainty and the fact that everyone from the National Cancer Institute to the World Health Organization is investigating cellular—phone radiation, many experts caution that it is far too early to give the phones a clean bill of health.
Cellular phones work by transmitting radio waves to base stations that connect calls into a network. The waves are a form of non-ionizing(非离子的) radiation-unlike, say, X rays, which have the power to change the atoms in human cells to potentially hazardous ions. Non—ionizing radiation can also be dangerous. At the high levels found in radar or inside microwave ovens(微波炉), it can heat and severely damage human beings. The question for scientists is whether the low—energy (and low-heat) signals from cellular phones can do harm.
Cancer studies have been inconclusive since 1993,when a Florida man brought an unsuccessful charge that blamed his wife’s fatal brain tumor(肿瘤) on her use of a cellular phone. In a frequently quoted 1997 report, Australian researchers exposed mice to two daily 30-min. amount of cellular-phone radiation for up to 18 months. The mice developed tumors at twice the rate of animals that were radiation-free. But the results haven’t been widely quoted, and some scientists question their relevance. For now m the best advice science can offer about cellular phones is handle with care.
21. According to the passage, science cannot offer us a definite connection between ________.
[A] cellular-phone radiation and changes in brainwave patterns
[B] X rays and the atoms in human cells
[C] the use of cellular phones and cancer
[D] mice exposed to cellular-phone radiation and the development of tumors

[B] the former are a form of non-ionizing radiation
[C] the latter are mainly used in hospitals
[D] the latter are low-energy and low-heat signals
24. The word “inconclusive” in the last paragraph means ________
[A] disapproved by the public
[B] not generally understood

Passage Two
Questions 26 to 30 are based on the following passage.
Everyone knows that the favorite food in the United States is the hamburger. It seems impossible, but people eat 34 billion hamburgers a year. This is enough to make a line of hamburgers around the world four times.
The favorite place to buy a hamburger is a fast-food restaurant. In these restaurants, people order their food, wait just a few minutes, and carry it to their tables themselves. They can eat it in the restaurant or take the food out and eat it at home, at work, or in a park. At some restaurants people can drive up beside a window. They order the food, and a worker hands it to them through the window. Then they eat in their cars.
Hamburgers are not the only kind of food that fast-food restaurant serve. Some serve fish, chicken, beef sandwiches, or Mexican food. They also serve fries (French fried potatoes), shakes (a drink made from milk and ice cream), soft drinks, and coffee.
Fast-food restaurants are very popular because the service is fast and the food is inexpensive. For many people, this is more important than quality of the food. These restaurants are also popular because the food is always the same. People know that if they eat at a company’s restaurant in the north or south of the city, the food will be the same. If they eat in New York or San Francisco, it will still be the same.
Fast service and low cost are important in the United States. One reason is that about 50 percent of all married women with children work outside the home. They are too busy and too tired to cook dinner every night.

Passage Three
Questions 31 to 35 are based on the following passage.
The word “generosity” has been devalued（贬值） somewhat recently. A millionaire man may give his friend a house in the beautiful suburb（市郊）; A rich man could fly halfway round the world to meet his friends for his birthday party. In this case, generosity is more an action of showing off than a sincere action of giving. And such showing off lacks the most important quality of real generosity: to offer kindness and love without expecting anything in return.
Real generosity, when you meet it is simply so pleasant. And as a quality, it belongs equally to the rich and the poor. A traveler in a faraway place felt it when he shared bread, room, even bed with a farmer’s family, whose general principle is “A guest in the house is God in the house”.
Another story is about a university student from Oxford. He did something out of his natural sense of generosity when he learned that his roommate couldn’t afford an impossibly expensive textbook, a book which was very rare in second-hand shops. Knowing that his roommate was far too proud to accept such a book as present from him, the rich student bought a new copy for 35 pounds at Blackwell’s bookshop. He dirtied it up a bit and tore off the paper cover, made a few dog-ears（卷页） and pencil marks against what he thought might be important parts, and wrote an invented name in the front. He even remembered to age the ink by putting it over fire. Then he went back, looking extremely proud of himself and claiming to have got the book in a second-hand bookshop. “Beaten them down to two pounds!” To make his friends believe him, he showed a receipt（收据）for the money by buying himself another book at the same place. Ten years later, the poorer student got to know the truth. Actually he was suspicious at the very beginning, though he didn’t force his richer friend to tell the truth. He appreciated the invaluable generosity as well as the valuable book.
Real generosity lies in the giver’s thoughtfulness, not its price or wrapping of the gift. It is one of the things which make us human and should be honored more than we do now.
31. A millionaire gives his friend a beautiful house, which is considered as ________ by the author.
[A] a sincere action of giving
[B] an action of showing off

[D] It lies in the giver’s thoughtfulness and kindness.
33. The Oxford student’s generosity to his roommate is shown in ________.
[A] his efforts to look for the textbook in all the second-hand bookshops
[B] his wisdom to beat the price of the book down to two pounds
[C] his ability to make the new book look old and cheap
[D] his consideration of offering the book without hurting his roommate’s self-respect
34. The poorer student didn’t force his rich friend to tell the truth because ________.
[A] he was too proud to know the fact
[B] he appreciated his friend’s thoughtfulness
[C] he was suspicious of the rich student’s intention

[D] A gift can’t be judged by its price or wrapping.
