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 example. Man, even five hundred years ago, was shorter than he is today. Now, on the average, men are about three inches taller. Five hundred years is a relatively (相对地) 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 larger ones! This is likely to bring about a physical change too. The head, especially the forehead, will grow larger.

Nowadays our eyes are being used too much. In fact, 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 (有…的趋势) 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 (敏感的) because they are used a great deal in modern life.

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 men and women are probably to be hairless!

Perhaps, all this gives the impression that future man will not be a very attractive (有吸引力的) person to look at! This may well be true. All the same, besides these changes, future man will still have a lot in common with us. He will still be a human being, with thoughts and feelings similar to our own.

（1） Future man is probably to be different from us in ________ ways.

A . two B . three C . four D . five
（2） Future man's head will grow larger because ________.

A . he will use his brain more and more as time goes on B . he makes use only 80% of the brain's capacity C . the other 80% of his brain will grow faster D . his brain has grown larger over the past centuries
（3） What will be probably TRUE about the man in the future?

A . He will have smaller eyes and will wear better glasses. B . His fingers will grow weaker because he won't use them. C . He will be hairless because hair is no longer useful. D . He will think and feel in a different way.
（4） What does the writer write the article for?

A . To give us some knowledge of future man. B . To show that man's life will be different in the future. C . To let us know future man will become shorter. D . To tell us future man will not use legs.

如图电路中，甲、乙两处分别接入电流表或电压表．当S闭合后，为使两灯均能发光，则（）

A . 甲接电流表，乙接电压表 B . 甲、乙均接电流表 C . 甲、乙均接电压表 D . 甲接电压表，乙接电流表

在下面一段文字横线处补写恰当的语句，使整段文字语意完整连贯。

世上有两个地方最为“神秘，一个是宇宙，①。破解宇宙秘密，人类可解开“我们从何而来的”的悬案，破解人脑的秘密，人类可得“我们将向何处去”的清晰展望。破解人脑的功能原理，依其原理制造“人工大脑”，已成为众多科学家追求的目标。人脑极其复杂，仿造人脑各有高招儿。美国授巨资启动的“脑计划”，是想通过“人造神经技术”修复人脑的病态，将因病受损的人脑部件用“人造大脑零件修复起来，以达到治疗阿尔茨海默氏症、癫痫、帕金森症等疾病的目的。美国的“脑计划”看似治脑病，②——能修复人脑，等于站在了再造人脑的门坎上了呀。

（1）平面 $\text{[math]}$ 平面 $\text{[math]}$
（2）在线段 $\text{[math]}$ 上是否存在点 $\text{[math]}$ ，使二面角 $\text{[math]}$ 的大小为 $\text{[math]}$ ？若存在，求出 $\text{[math]}$ 的长度；若不存在，请说明理由.

如图所示，电子枪接入电路后发射电子，其正下方水平直导线内通有向右的电流，则（）

A . 电子束从B射向A B . 电子束向上偏转，速率保持不变 C . 电子束向上偏转，速率越来越小 D . 电子束向下偏转，速率越来越大
