问题: 几个选择题

1the engineers are going through with their projects, ---the expenses have risen.
a even though b just because c now that d as though
答案是A请问有没有D这种说法,或者根本这是错误的?
2i will go, whether you ---with me or ---at home.
a will go ,stay Bwill go,will stay Cgo,will stay
Dgo stay
答案是D,请问为什么用它,可不可以是B
3 he speaks American English so fluently as if he ---English for ages in the USA.
alearn b learnt c have learnt d had learnt
答案是D,为什么不能是B,虚拟语气有那几种用法?

解答:

1,此题选A是从意思上选择,有D的说法,as if =as though好象,似乎

2,是考条件句的知识,主句将来,从句一般。

3,虚拟语气有几个固定结构,而且考试时考查的多的是过去完成时.

这个如果还有疑问,可以联系我的email
