Passage 1

 

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 to the head, in particular the A. man has been growing taller over the past 500 years B. man has got stronger eyes than he ever had C. man’s hair is getting thinner and thinner D. man’s limbs are getting weaker because he tends to make less use of them 查看答案 更多"Passage 1   "的相关试题: [单项选择] Passage 1   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.
