Question

B 

What will man be like in the future —5,000 or even 50 ,000 years from now? We can only make guesses,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,500 years ago,was shorter than he is today. Five hundred years is relatively a 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 to the head. In particular,the fore-head (前額) will grow larger.

Nowadays our eyes are in constant (持續(xù)不斷的) 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 the course of time because it does not serve a useful purpose any longer. In the future,then,both sexes are likely to be bald (禿頭的) .

Perhaps all this gives the impression that future man will not be a very attractive creature to look at!

This may 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.

Answer 1

41. B解析：主旨大意題。根據(jù)第一至五段 可知，本文主要介紹了未來人類的外貌可 能會發(fā)生的巨大變化。

42. D解析：細(xì)節(jié)理解題。根據(jù)第二段第二 句可知，人類的身高已經(jīng)發(fā)生了變化，故D 項(xiàng)正確。

B項(xiàng)與第三段內(nèi)容不符;其余兩 項(xiàng)描述的均為人類未來的變化趨勢而不是 人類正在改變的證據(jù)。

43. D解析:推理判斷題。根據(jù)第二段最后 三句可知，人類將更多地使用大腦，最終大 腦會變大，前額也會變大。

44. B解析：正誤判斷題。第五段指出人類 的頭發(fā)可能會消失，因?yàn)轭^發(fā)對人類將不 再有用。

45. C解析：細(xì)節(jié)理解題。根據(jù)最后一段前 兩句可知，通過上文描述的變化來看，人類 確實(shí)將變得不再那么有吸引力。
