189. What will man be like in the future—in 5,000 or even 50,000 years from now？ We can only make a guess, of course, but we can be sure that he will be different from what he is today. For man is slowly changing all the time. Let us take an obvious example. Man, even five hundred years ago, was shorter than he is today. Now, on average, men are about three inches taller. Five hundred years is a relatively short period of time, so we may assume that man will continue to grow taller. Again, in the modern world we use our brains a great deal. Even so, we still make use of only about 20% of the brain’s capacity. As time goes on, however, we shall have to use our brains more and more—and eventually we shall need larger ones. This is likely to bring about a physical change too: the head, in particular the forehead, will grow larger. Nowadays our eyes are in constant use. In fact, we use them so much that very often they become weaker and we have to wear glasses. But over a very long period of time it is likely that man’s eyes will grow stronger. On the other hand, we tend to make less use of our arms and legs. These, as a result, are likely to grow weaker. At the same time, however, our fingers will grow more sensitive because they are used a great deal in modern life. But what about hair？ This will probably disappear from the body altogether in course of time because it does not serve a useful purpose any longer. In the future, then, both sexes are likely to be bald. Perhaps all this gives the impression that future man will not be a very attractive creature to look at. This may well be true. All the same, in spite of all these changes, future man will still have a lot in common with us. He will still be a human being, with thoughts and emotions similar to our own. [共5题]

What is happening in our weather？ Of course we have never been able to predict exactly what the weather will be like, but now strange weather patterns are seriously affecting many parts of the world. For example, droughts (旱灾) in Mexico and Brazil have recently caused great crop losses and in the United States they have even had to make their own snow for the Winter Olympics!

Scientists have found that the cause of this strange weather is that the air circulation pattern has changed and is now more variable than earlier in the twentieth century. This means that different regions of the world get long spells (持续时间) of the same type of weather, whether hot , cold, wet or windy.

However, weather experts have different views about why this has happened. One theory is that the temperature of the sea has increased. Another is that man’s activities on earth have disturbed the balance of nature.

Whatever the cause, the economics of many countries in the world depend upon the weather. And until we know exactly what effect man’s activities are having on the weather, we cannot make changes which might help. So for the moment the only answer is …wait and see!

26. Which of the following statements is TRUE according to the first paragraph？

A. We have never predicted the weather.

B. Man is now able to control the weather.

C. Strange weather has appeared only in some North American countries.

D. It has always been impossible for man to predict the weather accurately.

27. The strange weather patterns on the earth can he best described as ________.

A. steady and balanced C. likely to cause serious disasters

B. changeable but predictable D. unpredictable but favorable to man

28. The word “affecting” in Paragraph 1 can be replaced by ________.

A. yielding good crops in C. causing few losses in

B. having harmful effects on D. producing desired effects on

29. We can learn from Paragraph 2 that ________.

A. weather patterns are similar in different regions of the world

B. the air circulation pattern remains unchanged in the last century

C. our weather depends on the changes in the air circulation pattern

D. it is possible to predict weather patterns over a long period of time

30. It can be learned from this passage that ________.

A. scientists have similar opinions about the changing weather

B. no one is sure about the cause of the changing weather

C. cutting down forests has affected the climate

D. the weather will become worse in the future

earchers have struck up a conversation with a man diagnosed as being in a vegetative (植物的) state. All they had to do was monitor how his brain responded to specific questions.

"They can now have some involvement in their destiny," says Adrian Owen of the University of Cambridge, who led the team doing the work.

In an earlier experiment, Owen's team asked a woman previously diagnosed as being in a vegetative state to picture herself carrying out one of two different activities. The resulting brain activity suggested she understood the commands and was therefore conscious.

Now Owen's team has taken the idea a step further. A man also diagnosed with VS was able to answer yes and no to specific questions by imagining himself engaging in the same activities.

The results suggest that it is possible to give a degree of choice to some people who have no other way of communicating with the outside world. "We are not just showing they are conscious, we are giving them a voice and a way to communicate," says neurologist (神经病学家) Steven Laureys of the University of Liege in Belgium, Owen's partner.

Doctors traditionally base these diagnoses on how someone behaves: for example, whether they can glance in different directions in response to questions. The new results show that you don't need behavioural indications to identify awareness and even a degree of cognitive proficiency. All you need to do is tap into brain activity directly.

The work "changes everything", says Nicholas Schiff, a neurologist at Weill Cornell Medical College in New York, who is carrying out similar work on patients with consciousness disorders. "Knowing that someone could persist in a state like this and not show evidence of the fact that they can answer yes/no questions should he extremely disturbing to our practice."

One of the most difficult questions you might want to ask someone is whether they want to carry on living. But as Owen and Laureys point out, the scientific, legal and ethical challenges for doctors asking such questions are formidable.

"They" in the second paragraph can be replaced by "______".

A．patients in a VS

B．researchers

C．monitoring machines

D．specific questions

根据内容回答下列各题.

Not long ago, there lived in Auckland a working family who dreamed about a house of their own. Anyone then could read in the newspapers about the building companies who offered to put people into a new house 51 only a $1,000 deposit. Of course, the remainder had to be paid off with interest over a period of twenty years or so.

The worker and his wife hopefully went to one of these companies 52 this wonderful offer. And the man in the office said．“Yes, sure. You bring along $1,000 and we can 53 you with a new house.” So the worker and his wife had to work hard and in twelve months’ time they returned to the building man with $1,000. But the man in the office said, “Look, I’m sorry, 54 we’ll need $1,500 now. Costs have gone up since we saw you last, you know.”

The couple thought it over and decided it would not take very long to save the extra $500 if they worked hard. In six moths they worked 55 overtime and saved the $500 in spite of the high rent they had to pay for their flat. Back to the building man they 56 with their $1,500. But to their surprise he 57 the deposit was now $3,000. Now somewhat wiser, the worker said, “And the next time, I dare say we’ll find the deposit rising once more. How have we 58 save the extra $1,500？” “Well”, said the man, “I think we can stabilize the situation for about twelve months. By the time you come with $3,000, we will have had the house 59 for you.

The couple left, sad at heart as they saw their dream house 60 . By the time they had saved the extra $1.500, no doubt the deposit would have become still higher, maybe $5,000, then $10,000 and then…!

51.

A.for

B.with

C.on

D.to
