选择题:
1.We _ in a good harvest because we _ enough rain.
A.didn't get…had had B.got…had had C.had got…had had D.got…hadn't had
正确答案:B,希望可以详细地讲一讲为什么。
2.John _ there since the year before,so he _ them.
A.had worked…knew B.had worked…had known C.worked…knew
D.worked…had known'
正确答案:B,希望可以详细地讲一讲为什么,特别是第二个空我不知道为什么要用过去完成时。

第一题:We got in a good harvest 是已经过去的事了,所以用过去时,we had had enough rain 是对good harvest 有影响的,要用完成时,而且是对过去有影响的,所以最终用过去完成时.
第二题:John had worked there since the year before用完成时是因为有since,so he had known them用过去完成时是因为他认识那些人后就忘了,而是还认识,一直持续到过去某一点,所以用过去完成时.
