Question

What will man be like in the future — in 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, even five hundred years ago, was shorter than he is today. Now, on average, men are about three inches taller. Five hundred years is relatively a short period of time, so we may suppose 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(容量). As time goes on, however, we shall have to use our brains more and more, and finally we shall need our brains more and more, and finally we shall need larger ones! This is likely to bring 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 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 motions similar to our own.

D．Man has been growing taller over the past 500 years.

【小題3】The change in man’s size of the forehead is probably because __________.

A．he makes use of only 20% of the brain’s capacity

B．his brain has grown larger over the past centuries

C．he will use his brain more and more as time goes on

D．the other 80% of his brain will grow in due time

【小題4】Which of the following is TRUE about a human being in the future?

A．He is hairless because hair is no longer useful.

B．He has smaller eyes and wears better glasses.

C．His fingers grow weaker because he doesn’t have to make use of them.

Answer 1

【小題1】B
【小題2】D
【小題3】C
【小題4】A
【小題5】B

解析【小題1】全文理解題。本文主要介紹未來人類的外貌。A未來的生活，與中心思想不符。C不具備概括性。D器官功能衰退不能概括未來人類身體的變化。
【小題2】細(xì)節(jié)理解。人類外貌逐漸變化的依據(jù)。見第二段第二句“man，even five hundred years ago was shorter than he is today.” ABC均為人類未來的變化趨勢而不是人類變化的證據(jù)。
【小題3】細(xì)節(jié)理解題。 第二段最后兩句說人類將更多地使用大腦，最終大腦變大，前額增大。
【小題4】細(xì)節(jié)理解題。第二段指出人類的頭發(fā)可能會消失，因為“it does not serve a useful purpose any longer”， 即頭發(fā)失去作用。第三段講人類將大量用手指，手指變得靈活敏感，所以C錯誤。D與后一段不符。
【小題5】推論題。從人類身體變化可以看出，經(jīng)常使用的器官部位，如大腦手指將變得發(fā)達(dá)。而不常用的器官會退化。A原文已經(jīng)直接提到，不能算作推論
