　　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。
