Why does the idea of progress loom so large in the modern world? Surely because progress of particu-lar kind is actually taking place around us and is more　and more manifesting. Although mankind has underg- __1

one no general improvement in intelligence or morality, it has made extraordinary progress in the accumu-lation of knowledge. Knowledge begins to increase as __2

soon as the thoughts of one individual could be com-municated to another by mean of speech. With the in- __3

vention of writing, knowledge could be communicated and stored. Libraries made education possible, and education in turn added libraries: the growth of knowl- __4

edge followed a kind of compound-interest law,which was greatly enhanced by the invention of printing. All this was comparatively slow until, with the coming of science, the tempo was suddenly risen. __5

then knowledge began to be accumulated according to a systematic plan. However, as soon as new knowl- __6

edge is acquired, it is now turned to practical account. What is called “modern civilization” is not the result of a balanced development of all man’s nature,but not of accumulated knowledge applied to practical __7

life. The problem now facing humanity is: what is going to be done with all this knowledge? Like is often __8

pointed out, knowledge is a two edged weapon which could be used equally for good or evil. It is now being __9

used indifferently for both. Could any spectacle, for instance, be more grimly whimsical than that gunners __10

using science to shatter men’s bodies while, close at hand, surgeons use it to restore them.

答案

【答案】

1. 把manifesting改为manifest

manifesting不能做形容词，而如果把它理解成现在进行词，后面又缺乏宾语，所以应该改为形容词manifest，表示 “显然的，明显的”。

2. 把begins改为began.

根据下一行出现的could可以判断本句是过去时。

3. 把mean改为means

by means of 是固定用法。

4. 在added后面加上to

如果add后面不加to，此句就表示 “把图书馆加到某个事物上去”，加上to，表示给图书馆增加了内容，符合句义。

5.把risen改为raised

rise是不及物动词，不能用于被动语态.

6.把However改为Moreover

此句的意思是:新知识一经获得，马上就得到实际应用。这是对上文的追加，不存在转折关系，因此应该用moreover

7.删除but后面的not

8.把Like改为As

9.把could改为can

主句为现在时，而从句也不表示虚拟，所以应该用现在时。

10.在that后面加上of

为了避免重复，这里用that指代spectacle，后面的gunner using是that 的内容，因此应该用介词of引出。
