1.Step One Lead-in Explain the basic usage of unreal conditionals.

A.We form unreal present conditionals like this:If… was/were/did … ,

…would/could/might do …

B. We form unreal past conditionals like this: If … had done…,

…would/could/might have done…

C. We form unreal future conditionals like this: If…was/were/did/should/were to…

…could/would/might do…

2.Step Two specific usage of unreal conditionals. A.条件句中虚拟语气的倒装

We can also put should, were and had at the beginning of an unreal conditional sentence. In this case, if is not needed any more. B.虚拟时间的错位

If you had followed the doctor’s advice, then you would be all right now.

If I hadn’t finished my composition by now, I would be working on it tomorrow. If she had prepared well for her lessons yesterday, she wouldn’t have so many difficulties now. C.用with, without，but for等介词短语或分词短语或者独立主格结构来代替条件从句。

We might have died without your help. Having known in time, we could have stopped it. But for your support, we would have failed in the match. D. should+动词原形; should可以省略：

1.suggest, advise, propose, recommend, insist, order, request, demand , urge, intend等词后所跟的宾语从句中
