A man stood at the door, not knowing whether he should enter orleave。We must prevent wasted water polluting the rivers选B

答案如下：(1)(不能决定是进去还是离开) whether he should enter or leave (不能缺主语）(2)（阻止废水污染河流)prevent the riverfrom waste water pollution .或者用protect 也可以（3）选A 理由是它不是一个同位语从句，所以不用that，后面的主it 不能在从句中出现whether to go in or to leave.prevent water pollutionBthe only先行为the only、the last等修饰时只能用that引导This is the only idea that (they think) is right.
