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 emotions similar to our own.

1.The passage mainly tells us that __________.

A. Man’s life will be different in the future

B. Future man will look quite different from us

C. Man is growing taller and uglier as time passes

D. Man’s organs’ functions will change

2.What serves as the evidence that man is changing?

A. Man has got stronger eyes now than he ever had.

B. Man’s hair is getting thinner and thinner.

C. Man’s arms and legs have become lighter and weaker.

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

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

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.

D. He thinks and feels in a different way.

5.It is implied that __________.

A. human beings will become less attractive in the future

B. parts of our bodies will become poorer if they are not used often

C. human beings hope for a change in the future life

D. future life is always predictable（可预测的）

【解析】

试题分析：本文根据现在的人类生活特点，推测未来人类在外貌上发生了有趣的变化。不管未来人类的外貌如何变化，他和现在的人仍有共同的特点。

1.B 细节理解题 第一段的第二句“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.”点明了文章的主题：未来的人类会和我们有很大区别。B项表述符合文意，故选B。

2.D 推理判断题 根据第二段的开头几句“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”可知现在的人比500年前的人高，证明了人类是在不断变化的。D项表述符合文意；A、B、C三项描述的是未来人类的特点，不能作为人类不断变化的依据，故选D。

3.C 细节理解题 根据第二段的最后几句“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”可知人类前额的大小发生了变化，因为他越来越多地使用大脑。C项表述符合文意，故选C。

4.A 推理判断题 根据第五段的“This will probably disappear from the body altogether in course of time because it does not serve a useful purpose any longer.”可知A项表述符合文意；根据第三段可知B项表述错误；根据第四段可知C项表述与文意不符；根据最后一段的最后一句可知D项表述不符合文意，故选A。

5.5】B 推理判断题 A项在最后一段中有明确的表述，不是推断出来的， 不能选；根据第四段第一句“On the other hand, we tend to make less use of our arms and legs. These, as a result, are likely to grow weaker.”可推测出B项表述；C项和D项与文意不符，故选B。
