專八改錯練習第六篇：

Why does the idea of progress loom so large in themodern world? Surely because progress of particularkind 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 theaccumulation 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(反白可見)：

1.把manifesting改為manifest
manifesting不能做形容詞,而如果把它理解成現在進行詞,后面又缺乏賓語,所以應該改為形容詞manifest,表示 “顯然的,明顯的”.
2.把begins改為began
根據下一行出現的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:新知識一經獲得,馬上就得到實際應用.這是對上文的追加,不存在轉折關系,因此應該用moreover.
7.刪除but后面的not
8.把Like改為As
9.把could改為can
主句為現在時,而從句也不表示虛擬,所以應該用現在時.
10.在that后面加上of.
為了避免重復,這里用that指代spectacle,后面的gunner using是that 的內容.因此應該用介詞of引出.?
