C

　　A scientist who developed a way to calculate(计算) how much water is used in the produciton of anything form a cup of coffee to a hamburger was awarded the 2008 Stockholm Water Prize.

　　Professor John Anthony Allan of the University of London in Britain won the award for introducing the idea of "virtual water(虚拟水)",a calculation method that has changed the nature of trade policy and research.

　　Allan has written seven books and published more than 100 papers.

　　The Stockholm International Water Institute said this idea is now embedded(埋藏) in the production of foods and industrial products.The institute said Allan's work had made a big effect on global trade policy and research,especially in water - scarce(缺水) regions.

　　"The improved understanding of trade and water management issues on local,regional and global scales are of the highest value for the successsful and sustainable(可持续的) use of water resources,"it said.

　　"People do not only use water when they drink it or take a shower,"the institute said. "Behind the morning cup of coffee,there are 140 liters of water that was used to grow,produce,package and ship the beans."That is about as much water as a person in England uses on average for all daily drinking and household needs.

　　"For a single hamburger,about 2,400 liters of water are needed.In te USA ,the average person uses nearly 7,000 liters of virtual water every day" It said that was more than three times the average use of a Chinese person.

　　64.Allan was awarded the prize because ______.

　　　A.he wrote seven books on trade policy

　　　B.he published more than 100 papers on water management

　　　C.he found a new kind of water in water - scarce areas

　　　D.he came up with the idea of virtual water

　　65.Which of the following is TRUE according to the passage?

　　　A.The average American uses about 7,000 liters of water a day.

　　　B.The average Chinese uses nearly 2,300 liters of virtual water a day.

　　　C.An Englishman usually drinks about 140 liters of coffee a day.

　　　D.A hamburger usually contains about 2,400 liters of water.

　　66.What effect does the idea of virtual water have?

　　　A.It helps us realize the importance of trade.

　　　B.It helps people do successful business.

　　　C.It helps us make use of water scientifically.

　　　D.It tells us how much water we use a day.

　　67.What does the underlined word "it" in the last paragraph refer to?

　　　A.The University of London.

　　　B.The calculation method.

　　　C.The Stockholm International Water Institute.

　　　D.The trade policy and research.

阅读下列短文，从所给的四个选项中，选出最佳答案。

　　     A question often put to specialists on fishes is "How long do fishes live?" Specialists find it difficult to give an exact answer though it seems to be a very simple question. Actually this question is not so simple as it seems. There are thousands of different kinds of fishes, and they are different from one another in size and life-span (寿命). Moreover (此外), it is not easy to find out just how long a fish lives in its natural state.

　　     We can find out how old a fish is by studying its size, but we cannot say how much longer it would have lived if we had not caught it.

　　     We may feed fishes and record their life-span, but we cannot be sure that this is the length of time they would have lived if they had　　 been left alone.

　　     We may make markings to show how fast the fishes grow so that we can calculate (计算) the age of the largest on record, but unless this large fish dies of old age, we are still not in a position to know　　 its natural life-span.

　　     Unlike human beings, fishes do not stop growing when they reach maturity (成年). They continue to grow as long as they live, although　　 the rate of growth slows down in grown-up fishes.　　 　　

(1) What specialists feel difficult to know is ________.

[　　]

A. the age of fishes　　　　

B. the size of fishes　　　　

C. the life-span of the fishes he feeds 　　

D. the life-span of fishes living freely 　　

(2) We may know a fish's age by studying __________.

[　　]

A. how heavy it is　　

B. how big it is　　　　

C. its rate of growth　　

D. the position it lives　　

(3) Which of the following is true?

[　　]

A. The heavier a fish is, the older it is. 　　

B. If we let a fish alone, we can hardly know its life-span. 　　

C. Old as a fish is, it will keep growing fast before its death. 　　

D. When a man is old, he will grow much more slowly than an old fish. 　　

(4) Which of the following is not true?

[　　]

A. If we feed a fish from its birth to its death, we correctly record its life-span.

B. A fish's weight has nothing to do with its life-span.

C. Human beings stop growing when they have grown up.

D. Specialists can know how fast a fish grows, but they do not know how long it will live.　　

(5) Which of the following do you think is the best title for this　　 passage?

[　　]

A. How Long Do Fishes Live? 　　

B. Easy or Difficult?　　　　

C. The Difference Between Human Beings and Fishes. 　　

D. Specialists and Fishes.

　 Edmund Halley was an English scientist who lived over 200 years ago. He studied the observations of comets(彗星)which other scientists had made. The orbit of one particular comet was a very difficult mathematical problem. He could not figure it out. Neither could other scientists who dealt with such problems.

　 However, Halley had a friend named Isaac Newton, who was a brilliant mathematician. Newton thought he had already worked out that problem, but he could not find the papers on which he had done it. He told Halley that the orbit of a comet had the shape of an ellipse(椭圆形).

　 Now Halley set to work. He figured out(解决，计算出)the orbits of some of the comets that had been observed by scientists. He made a surprising discovery. The comets that had appeared in the years 1531, 1607, and 1682 all had the same orbit. Yet their appearance had been 75 to 76 years apart.

　 This seemed very strange to Halley. Three different comets followed the same orbit. The more Halley thought about it, the ore his thought that there had been three different comets as people thought. He decided that they had simply seen the same comet three times. The comet had gone away and had come back again.

　 It was an astonishing idea! Halley felt certain though to make a prediction(预言)of what would happen in the future. He decided that this would appear in the year 1758. There were 53 years to go before Halley’s prediction could be tested. In 1758 the comet appeared in the sky. Halley did not see it, for he had died some years before. Ever since then that comet had been called Halley’s comet, in his honor.

1. Edmund Halley figured out the orbit of ____.

　 A. some different comets appearing several times

　 B. the same comet appearing at different times

　 C. three different comets appearing at the same time

　 D. several comets appearing at the same time

2. Halley made his discovery ____.

　 A. by doing experiments

　 B. by means of his own careful observation

　 C. by using the working of other scientists

　 D. by chance

3. Halley made a surprising, but correct prediction in the year____.

　 A. 1704　　　　　　　　　　 B. 1705

　 C. 1706　　　　　　　　　　 D. 1707

4. This passage in general is about ____.

　 A. Halley and other scientists

　 B. the orbit of a comet

　 C. Newton and Halley

　 D. Halley and his discovery

5. Which of the following is TRUE?

　 A. Edmund Halley was an American scientist.

　 B. Halley made his discovery by doing experiments.

　 C. Isaac Newton was a famous mathematician.

　 D. The orbit of a comet had the shape of an around.

C
