1. Passage Twenty-One 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 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 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 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? It 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. The passage tells us about ( ) .

4. Passage Twenty-Two Though some people have suggested that women should return to housework in order to leave more jobs for men， the idea has been rejected by both women and men in public opinion polls (民意测验). Lately some union officials have suggested that too many women are employed in type of work more suitable for men and that women should step aside to make way for unemployed young men. They argue that women—especially women in their childbearing years actually delay economic development and result in lower productivity， poor quality and inefficiency. To solve the problem， they have suggested that the working women stay at home while their husbands or brothers were given double wages. They argue that under these circumstances， families would retain their same level of income， and women could run the house and raise children much better. The suggestion has been rejected by 9 out of 10 people polled. A hundred persons in a big city were questioned last summer. Out of 50 women， 46 said they were unwilling to leave their jobs， no matter what the situation was. The other 4 said they would like to return home if their jobs could be taken by their sons or daughters. Of 50 men polled， only 6 said they would like to see their wives give up their jobs， if it meant higher wages for themselves. Some other people have suggested another way called “phased employment theory” . The theory suggests that a woman worker take leave from her job when she is seven months pregnant (妊娠) and stay off the job until her baby reaches the age of 3. It suggests that women on leave receive 75 percent of their normal salary and be allowed to return to work after the 3-year period. This will benefit children， women， their families and the society. Some of those polled， both women and men， felt the idea is a good one. It definitely seems to be more acceptable than the suggestion that women return to home forever. From the passage we can see “phased employment” means ( ) .

A. two or more women share the same job

B. women stay at home on weekdays and go to work on weekends or holidays

C. a woman should resign her job forever if she has a child

D. women are allowed to take leave from their jobs during their childbearing years
