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 morali-
ty, 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 print-
ing. 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 ac-
count. 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 go-
ing 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.

參考答案及解析：
1.把manifesting改為manifest
manifesting不能做形容詞,而如果把它理解成現(xiàn)在進(jìn)行詞,后面又缺乏賓語,所以應(yīng)該改為形容詞manifest,表示 “顯然的,明顯的”.

2.把begins改為began
根據(jù)下一行出現(xiàn)的could可以判斷本句是過去時.

3.把mean改為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 “把圖書館加到某個事物上去”,加上to,表示給圖書館增加了內(nèi)容,符合句義.

5.把risen改為raised
rise是不及物動詞,不能用于被動語態(tài).

6.把However改為Moreover
此句的意思是:新知識一經(jīng)獲得,馬上就得到實際應(yīng)用.這是對上文的追加,不存在轉(zhuǎn)折關(guān)系,因此應(yīng)該用moreover.

7.刪除but后面的not

8.把Like改為As

9.把could改為can
主句為現(xiàn)在時,而從句也不表示虛擬,所以應(yīng)該用現(xiàn)在時.

10.在that后面加上of.
為了避免重復(fù),這里用that指代spectacle,后面的gunner using是that 的內(nèi)容.因此應(yīng)該用介詞of引出.
