虚拟语气的用法和时态是什么?
退时态:真实语气中的现在时变成过去时,过去时变成过去完成时,将来时变成过去将来时
1.条件句中:
If it were not for…;If it hadn’t been for…这两种句型表示“要是没有”,相当于but for
If it had not been for the PLA man,he would not be studying English now.
if…only…(或If only…)表示“要是…就好了”
1.名词性从句:
demand/suugest/order/insist/propose/request/ask/advise/prefer/command/desire that…
They demanded that the aggressor troops (should) be withdrawn immediately.
由insist引导的宾语从句可以虚拟也可以不虚拟:
He insisted that he was right.坚持认为
He insisted that we should agree with him.坚持某事
由suggest引导的宾语从句可以虚拟也可以不虚拟:
His white face suggests that his not healthy.表明
He suggested that we have a rest.建议
If I could only see him once!
If only I had listened to your advice.很明显,这种句型省略了主句
2.其他状语从句中:
as if/as though/even if…
Tom looked sad as if he had heard bad news.
I won’t lend you any money even I had money.
3.名词性从句:
wish that…(hope后的宾语从句不虚拟)
I wish I were as strong as you.
How I wish it wasn’t raining!
would rather/would sooner/had rather that…表示“宁愿”
I would rather they came tomorrow.
I could go myself but I would sooner you went.
I had rather you told him than I did.
It is time/high time that…
It is time we went to bed.
+(should) do:
现在——did
过去——had done
将来——were to do
与现在事实相反的用过去式,与过去事实相反的用过去完成式,与将来事实相反的用过去将来时,与过去将来事实相反的用过去将来完成式.现在——did 过去——had done 将来——were to do 也可以用would加动词原形.
