（1）She will tell us why she feels so strongly that each of us has a role______in making the earth a better place to live.
A.to have played B.to play
C.to be played D.to be playing
(2)Mrs.Brown was much disappointed to see the washing machine she had had______went wrong again.
A.it B.it repaired
C.repaired D.to be repaired

请告诉我怎么做以及为什么这样做，谢谢！~~~~~~~
正确答案是（1）C（2）D
但是为什么呢？

1,B 句子用的是将来时，所以不必用完成时。each of us has a role to play ＝each of us play a role
2,C,那是个定语从句，SHE HAD THE WASHING HAD REPAIRED

1, b
2, c

1，b “to play a role in Sth.”是固定搭配，意为在某方面起什么什么作用，此处是一个词组的变形。

2，c 首先根据句意推断，a 答案意义不通，排除；其次，应明了 she had had______是修饰the washing machine的一个后置成分，而不是一个完整句子，所以b答案不能选。因为it是宾语；d答案to be done结构表示将来要做什么，与题意“已经修过”不符。
