定语从句练习题(帮我解释一下理由）
1)It may pollute the grass that ________________
A.animals are fed on B.feeds animals
C.animals are fed D.feed on animals
2)She had two daughters ,________ became doctors
A.all of them B.all of whom
C.both of them D.both of whom (w为什么这边要用whom_)
1.A 2.D
答
2.daughters后面有一个逗号,说明它应该是一个包含从句的句子,如果选C,both of them became doctors是一句完整独立的句子,就和前面的句子没有关系了,那就不应该用逗号而要用句号.既然用了逗号,就得用WHOM,存在介词OF,就不能用WHO.
如果你以后题目做多了,就会碰到从句中用WHO的情况,这个问题到时候再说吧.
1.fed on sth,以...为主食,完整的应该是animals are fed on grass.
