急！！虚拟语气问题

she didn't tell anybody where she would go lest her husband____her.A.find B.had found C.finds D.would find为什么是选A呢？
Electronic computer must be made very small.Otherwise,it___impossbile for them to be put in a satellite.A.be B.is C.would be D.was为什么选C？这是对什么时候的虚拟？

Answer 1

1.she didn't tell anybody where she would go lest her husband____her.
A.find B.had found C.finds D.would find
本题中，lest her husband (should) find her前面“找”的动作可能持续到现在，或者过去某个时间点就完成，故用lest引导虚拟语气；

2.Electronic computer must be made very small.Otherwise,it___impossbile for them to be put in a satellite.
A.be B.is C.would be D.was
这是对将来时态的虚拟。电脑的微型化是一般时态，如若不微型化，后果是将不可能带上卫星。

Answer 2

1.lest引导的从句一般要用虚拟语气(作以免,以防的意思)，形式是“should+动词原形”或省掉should,所以第一题应该填(should) find.

2.对将来时态的虚拟.但我不确定如果填were是否也正确.

以上.共勉之.
