Mrs.Brown was much disappointed to see the washing machine she had __ went wrong again.
A.it repaired
B.to be repaired
C.to repair
D.repaired
为什么?不能选A?
请详细说明.
这里有两点要注意:1.是一个定语从句 2.用到了have sth.done结构
这个句子的完整形式应该是Mrs.Brown was much disappointed to see the washing machine that she had repaired went wrong again.定语从句的关系词that实际上充当了have sth.done结构中的sth.所以当然不能再用一个it,同时可以看到that这时是作宾语的,所以可以省略掉,于是成为Mrs.Brown was much disappointed to see the washing machine she had repaired went wrong again.
