虚拟语气是一种动词形式,表示说话人的一种愿望,假设,怀疑,猜测,建议等含义,虚拟语气所表示的含义不是客观存在的事实.
1． 非真实条件句
1）时态：可以表示过去,现在和将来的情况.它的基本特点是时态退后.
a.同现在事实相反的假设.
句型 ：
条件从句一般过去时+主句would/might/should(should 仅用于第一人称) +动词原形
If they knew that Soot was ill and we used the money to take him to the vet,(they would understand why the house was in a mess).
b.表示于过去事实相反的假设.
句型：条件从句过去完成时+主句would/might/should(should 仅用于第一人称)have+ 过去分词
If she had worked harder,she would have succeeded.
2．在宾语从句中的应用
在表示命令、建议、要求等一类动词后面的从句中：
order,suggest,propose,require,demand,request,insist,command,insist + that sb (should) do
注意,suggest作"表明,暗示"的意思理解时,不需要用虚拟语气
Her tears on her face suggests that she has been crying just.
她脸上的泪痕表明她刚刚哭过.
1) I suggest that we (should) put off the meeting till next week.
2) He insisted that they (should ) be informed of our descision
3．.用于wish后面的从句,表示与事实相反的情况,或表示将来不太可能实现的愿望.
1）I wish I knew the answer.
2) Iwish I had known you earlier.
4.if only
if only则表示如果……就好了,除非,If only也可用于陈述语气.
If only Dad were here,he would be quite.除非爸爸在这,他才会安分点.(爸爸现在不在这,与事实不符,期待不会实现)
If only he comes early(期待可实现,故无需虚拟语态).但愿他早点回来.
5.would rather +从句（从句中的谓语动词用一般过去时表示将来）
1) I’d rather you left me alone.
2) I’d rather you didn’t tell he now.
6.should have/could have+完成时表示“本应该、本可以”
1) None of us stopped to think and we should have.
2) We could have been good friends.
