    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.

材料一清朝的时候有一位外国使节来到中国，他先声明自己是不会向中国的皇帝下跪的，中国官员出于礼仪，带他从外城沿着御道去晋见皇帝。当他穿过第一道城门大清门的时候，他看到了高大的红色城墙，金色的琉璃瓦，远远望见的是天安门。穿过天安门，中间是北京最高的城门午门，当你越走近午门，人显的越渺小，这时使节的心理已经发生很大的变化了。穿过午门，远远望见的是白色的金水桥、白色的华表和金瓦红墙的端门，穿过端门，终于进入紫禁城，前面是通往太和殿的最后一道门太和门，穿过太和门之后，高高坐落在三层白色石阶上的太和殿呈现在眼前，这位使节再也支撑不住了，“扑通”跪在了地上。他说：我跪的不是中国的皇帝，我跪的是中国伟大的建筑。

材料二在平津战役时，***等中共领导人特意通过地下党派人去询问当时著名的建筑学家梁思成，哪些地方需要保护，梁思成给了他们一张画满圆圈的地图，这张地图很快就挂在了作战指挥部的墙上。北平后来和平解放，这座历史文化名城得以完整的保留了下来。

材料三因为城市建设的需要，更因为对建设与保护的关系没有处理好，1957年，47座城门城楼、箭楼和角楼被拆除，如今仅有3座尚存。建国初北京有大小胡同7000余条，到20世纪80年代统计只剩下3900条左右，近一两年正在以每年600条的速度消失；四合院、三合院、二合院30万座左右，目前仅剩约10几万座，被政府列入重点保名册的院子，只有几百个。北京永远失去了作为一个完整的历史文化名城申报世界遗产的资格。被拆除的城墙位置现在是北京核心的二环路，外面已经发展到了六环了。故宫、天坛等保存完好的单项已经列入世界文化遗产，可是这些保留下来的文化遗产现状又是如何呢？2007年5月2日，北京故宫接待游客近11、48万人次，超过最大容量2、3倍。
