Future man is likely to be different from us _____________________. 
(A)in technology

(D)in psychological perspectives

As time goes on, we shall have to use our brains more and more-and eventually we will need larger ones!(頭腦變大)

This is likely to bring about a physical change too;(外觀改變)

the head, in particular the forehead, will grow larger.(頭變大)

Besides, 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.(眼睛戴眼鏡)

But over a very long period of time it is likely that man’s eyes will grow stronger.(眼睛強化)

On the other hand, we tend to make less use of our arms and legs.(少用手臂及腳).(少用手臂及腳)

These, as a result, are likely to grow weaker.

Nonetheless, our fingers will grow more sensitive because they are used a great deal in the modern life.(手指靈敏)

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.(頭髮消失)

In the future, 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. However, 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 ours.
