Presentation

Unreal conditionals can be used in three different tenses: 1. to state a present condition or situation that is not real or is imaginary.

TIP: 1) Would, could and might are often interchangeable, but with some difference in meaning. Would → intention; plan

Could → ability; possibility

Might → probability

2. to use unreal conditionals to refer to an imaginary past action.

3. to use unreal future conditionals to talk about imaginary future situations. 三种用法的总结：

表示与事实情况相反

表示与现在事实情况

相反(present) 表示与过去事实情况

相反(past) 条件从句的谓语形式

过去式(did/were) (be常用

were) 过去完成式

(had +done) 主句的谓语形式

would/could/might/should + do would/could/might/should +have done

表示与将来事实情况

相反(future) ①过去式(did)/(were) ②should + do

③were to do

would/could/might/should + do 4. 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. Step 3. Practice
