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. 参考答案及解析： 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.
