1.We _____(reach)the station before ten o'clock.
这到题答案好象是用过去完成时,但我不确定,如果是的话,为什么不能用一般过去时?
2.We ____in a good harvest because we ____enough rain.
A.didn't get,hadn't had B.got,had had
C.had got,had had D.got,hadn't had
请说明理由,
1.We _____(reach)the station before ten o'clock.
have reached
before与现在完成时连用
2. a
because引导的从句发生在主句之前 所以从句用完成时,主句用一般时
它们的时间都应该是过去 所以选择a
