一些虚拟语气问题,麻烦解析,我会追加分的

为什么?
2.-I thought you would come back tomorrow.

a.don't have b.didin't have c.will not have d.would not have
我觉得是d,可是答案是b,为什么?
3.I would come earlier,but I_that you were waiting for me.
a.didn't know b.hadn't know c.would have known d.haven't know
但我选了b
4.Let's say you could go there again,how_feel?
a.will you b.should you c.would you d.do you
不明白这句话为什么用虚拟
5.he kept it carefully in a bottle lest_
a.would burn b.burned c.was burning d.should burn
为什么
6.Jane wishes he _ the football game instead of the film
a.saw b.see c.had been seen d.had seen
明明是wishes,为什么选d,不选a
7.he felt as if he_more time to study for the test
a.needs b.were needed c.needed d.need
的原因
8.if she coul sew,_
a.she make a dress b.she would have made a shirt c.she would had made a coat
为什么
9.our teacher died of cancer last term,otherwise he_now
a.would still be working b.would stiilhave worked
c.should stiil work d.will still worked
为什么
10.the doctor did everything he could so that he_save the sodier's life.
a.might b.must c.had to d.was able to
我选d,
辛苦了
1 d.是(should)+fail,for fear that用加should的虚拟语气
2 b.表示过去已经发生的事.如选d表示与现在事实相反
3 跟第二题同一类型
4 这句话的意思是“我们打比方你还能够再去那里,你将有什么感受”,这件事是想象中的,不是实际的,所以用虚拟语气
5 lest(否则),in case,for fear that,suggest ,purpose,order,require等后加用(should)+v
6 wish后面的从句中,如果指现在或将来的愿望,动词用过去式,而表示过去没有实现的愿望,动词用过去完成时
7 as if ,as though后面的方式从句中,表示与现在事实相反或对现在的情况有所怀疑,动词用过去时,如果表达的是想象中的过去的动作,用过去完成时
下面的只有通过语感了,感觉是虚拟语气,就不会选错了,比如说最后一题,知道是虚拟语气,就这能选a
