问题描述:

the babies ___ are very healthy
after whom the nurses look
whom the nurses look after
whom the nurses look
whom the nurses looks after

选第二个答案
1.含有介词的动词短语一般不拆开使用,如:look for,look after,take care of等
(1) This is the watch which/that I am looking for.(T)
(2) This is the watch for which I am looking.(F)
nurses是复数 因此不用三单
