D

       It is hard to predict（预言）how science is going to turn out, and whether it is really good science, it is impossible to predict．If the things to be found are actually new, they must be unknown in advance．You cannot make choices on this matter．You either have science or you don’t and if you have it you have to accept the surprising and disturbing pieces of information, along with the neat and useful bits．

       The only solid piece of scientific truth about which I feel totally confident is that we don’t know enough about nature．Indeed, I regard this as the major discovery of the past hundred years of biology．It is, in its way, a clear piece of news．It would have amazed the brightest minds of the 18th century to be told by any of us how little we know and how strange the way ahead seems．In earlier times, they either pretended to understand how things worked or simply made up stories to give answers．Now that we have begun exploring seriously, we are catching sight of how huge the questions are, and how far from being answered．Because of this, we are sorry．It is not so bad being ignorant（无知的）if you are totally ignorant; the hard thing is knowing in some details the reality of ignorance, the worst spots and here and there the not so bad spots, but no true light at the end of the tunnel nor even any tunnels that can yet be trusted．

       But we are making a beginning, and there ought to be some satisfaction．There are probably no questions we can think up that can’t be answered, sooner or later．Within our limits, we should be able to work our way through to all our answers, if we keep at it long enough, and pay attention．

51．Acoording to the writer, really good science________．

       A．would surprise the brightest minds of the 18th  century．

       B．will help people to make the right choice in advance

       C．will produce results which cannot be predicted

       D．will bring about disturbing results

52．It can be inferred from the passage that scientists of the 18th century________．

       A．thought that they knew a great deal and could deal with most problems of science．

       B．knew that they were ignorant and wanted to know more about nature

       C．were afraid of facing up to the realities of scientific research

       D．did more harm than good in man’s understanding of nature

53．Which of the following is NOT mentioned about scientists in earlier times?

       A．They falsely declared to know all about nature．

       B．They did not believe in results from scientific observation．

       C．They paid little attention to the problems they didn’t understand．

       D．They invented false rules to explain things they didn’t understand．

54．What is the writer’s attitude towards science?

       A．He is sorry because of the ignorance of scientists．

       B．He is delighted because of the latest scientific findings．

       C．He is doubtful because of the great difficulties in scientific research．

       D．He is confident though he knows well the great difficulties in scientific research．

55．The writer believes that sooner or later________．

       A．man can’t deal with all the problems he can find because of the limits of human knowledge．

       B．man can find solutions to whatever questions concerning nature he can think up

       C．questions concerning nature are outsiede the field of scientific research

       D．man can think up all the questions and answer them all．

Although man has known asbestos for many hundreds of years, it was not until 160 years ago that it was mined for the first time on the North American continent. H. W. Johns, owner of a New York City Supply Shop for roofers, was responsible for(对…负责) the opening of that first mine.

Mr. Johns was given a piece of asbestos which had been found in Italy. He experimented with the material and then showed its surprising powers to his customers. After putting on a pair of asbestos gloves, which looked much like ordinary work gloves, he took red-hot coals from the fireplace and played with them in his hands. How astonished the customers were to discover that he was not burned at all. You can well imagine that he had increasing business in asbestos roofing materials. However, because it was very expensive to transport (carry) them from Italy to the United States, Mr. Johns sent out a young scientist to seek a source nearer home. This young man found great vein(岩脉), in the province of Quebec in Canada.

Ever since 1881 Quebec has led the world in the production of this unusual mineral, which is made up of magnesium, silicon, iron, and oxygen. When it is mined, the asbestos is heavy, just as you would expect a mineral to be. When it is separated, a strange thing happens; the rock breaks down into fine, soft, soapy fibres(纤维).

Scientists do not know why the rock can be separated easily into threads(线), but they have found thousands of uses of this fireproof material, of the so-called “cloth of stone”.

Which title best expresses the main idea of this passage?

A. Asbestos mined in Canada        B. Fireproof matter

C. A “wonder” mineral                 D. A new roofing material

Johns proved his ability as a salesman by_______.

A. going into roofing business      B. carrying asbestos from Italy

C. sending a trained scientist         D. showing the use of asbestos gloves

Which is the most important character of asbestos that the author wants to show us?

A. It is like thread.               B. It feels soapy.

C. It burns easily.                 D. It is unusually heavy.

The author’s main purpose in writing this passage was to _______.

A. show the need for more scientists

B. compare asbestos with other minerals

C. increase the sales of asbestos

D. present facts about asbestos

Wild animals seem to have escaped the Indian Ocean tsunami(海啸), adding weight to ideas they possess a “sixth sense” for disasters, experts said on Thursday.

Sri Lanka wildlife officials have said the giant waves that killed over 24,000 people along the Indian Ocean island’s coast seemingly missed wild beasts, with no dead animals found.

“No elephants are dead, not even a dead hare or rabbit. I think animals can sense disaster. They have a sixth sense. They know when things are happening,” H.D. Ratnayake, deputy director of Sri Lanka’s Wildlife Department, said on Wednesday.

The waves washed floodwaters up to 3 km (2 miles) inland at Yala National Park in the southeast, Sri Lanka’s biggest wildlife reserve and home to hundreds of wild elephants. “There has been a lot of evidence about dogs barking or birds migrating before volcanic eruptions or earthquakes. But it has not been proven,” said Matthew van Lierop, an animal behaviour specialist at Johannesburg Zoo.

“There have been no specific studies because you can’t really test it in a lab or field setting,” he said.

Other authorities agreed with this conclusion.

“Wildlife seem to be able to pick up certain phenomenon, especially birds. There are many reports of birds detecting coming disasters,” said Clive Walker, who has written several books on African wildlife.

Animals certainly rely on the known senses such as smell or hearing to avoid danger such as predators(食肉动物).

The idea of an animal “sixth sense” is a lasting one that the evidence on Sri Lanka’s damaged coast is likely to add to.

This passage is mainly about________.

A. the damage that was caused in the Indian Ocean tsunami

B. why animals can save them from natural disasters

C. how to protect the wildlife when disaster happens

D. the different opinions about animals’ natural power

Which of the following is true according to the text?

A. It has been proved that animals have a “sixth sense”.

B. Research has been made on the special movements of animals before disasters.

C. It’s generally considered that animals can sense the coming of disasters.

D. Animals have depended on the known senses to escape the Indian Ocean tsunami.

What does the term “sixth sense” in the text means?

A. It is the natural ability of animals that can save them from danger.

B. It is the animal’s imagination in the brain.

C. It is some hidden power to say in advance that something will happen.

D. It is a kind of sense that is the same as smell or hearing.

Which section does the text most probably appear in a newspaper?

A. News Report.        B. Discovery.       C. Science Fiction.      D. Culture.


C
Sitting in a dark movie theater with your friends. and a tub of popcorn (H^) sounds like a perfect way to spend a Saturday night, and it could be, if you are willing to share your popcorn with the entire row of moviegoers around you.
A review of movie-theater popcorn reveals an alarming amount of fat, salt and calories in even the smallest sizes. A large tub of popcorn at Regal Cinemas, for example, holds 20 cups of popcorn and has 1,200 calories, 980 milligrams of sodium (钠) and 60 grams of saturated (饱和的) fat. Adding just a tablespoon of butter adds 130 calories. And do not forget that it comes with free refills.
Not so hungry? The medium size popcorn, even the small, at 11 cups, delivers 670 calories, 550 milligrams of sodium .and 24 grams of saturated fat. The findings may surprise those who believe it is a relatively healthy snack. In fact, plain air-popped popcorn is low in calories and free of saturated fat. Movie theater popcorn, however, is popped in oil, often coconut oil, which is 90 percent saturated fat. Add salt to it, and your once-healthy snack turns into a health offender.
One way to make your popcorn healthier? Ask the theater to pop the corn without salt. The best way to make your movie snack healthier, however, would be to skip the popcorn.
"You could share a tub of popcorn with 10 friends," Dr. Nestle, a professor of nutrition at New York University, said. "Or, what a concept, watch the movie without eating anything."
64. The review finds that movie theatre popcorn may contain all the following EXCEPT ______.
A. butter           B. sodium                 C. saturated fat         D. pepper
65. What does the author think of popcorn prepared in coconut oil?
A. It is a healthy snack.                        B. It does harm to our health.               C. It looks like a perfect choice.                 D. It is very nutritious.
66. Which kind of popcorn causes the least health concern?
A. Movie theatre popcorn.                                 B. Popcorn sold at Regal Cinemas.          C. Large size popcorn.                                      D. Plain air-popped popcorn.
67. What is Dr. Nestle's suggestion to moviegoers?
A. Avoid eating popcorn.                                  B. Share popcorn with friends.              C. Not eating anything in the movie theatre.          D. Try eating other kind of food.
