Americans like to look the other person in the eyes when they are talking. If you don’t do so, it means you are bored, hiding something, or are not interested. But when you stare at someone, it is not polite. For Americans, “thumbs up” means yes, very good, or well done. “Thumbs down” means the opposite. To call a waiter, raise one hand to head level or above. To show you want to the check, make a movement with your hands as if you are signing a piece of paper. It is all right to point at things but not people with the hand or index finger. Americans shake their index finger at children when they scold them and pat them on the head when they admire them.

We can only make a guess, of course, but we can be sure that we will be different from what we are 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 short 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 large ones! This is likely to bring about a physical change too: the head, in particular the forehead, well grow larger. Nowadays our eyes are in constant use. In face, 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(秃的)! Perhaps all this gives the impression that future man will not be 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. 48.

A. have a large forehead and weaker eyes B. have similar thoughts and emotions with us C. need glasses to see better D. be bald and attractive (责任编辑：admin) |
