SAT 句子提升的两道题 继续求教

  • 怎么说呢.主动比被动好.

    虽然那句话也对.

    但是

    这个机构的调查显示,

    by括起来不看.

    it指代agency,而且是主动.

    by后面是状语,删掉不看.

    那原句是这样The agency reports that industrial pollutions has been successfully reduced to acceptable levels.就有点儿怪了,不知道是谁的工业污染.

    改后是这样,The agency reports that it has succeeded in reducing industrial pollution to acceptable levels.就非常明确了.
