if 条件句和虚拟语气
if 条件句遵守主将从现的原则.
if it is fine tomorrow ,we will go out .如果明天天气好,我们就出去.
虚拟语气表示相反.
表示和现在相反,从句用一般过去时.if i had a big house ,
如果我有一个大房子.我会怎样怎样.(其实没有大房子,和现在的情况相反)
表示和过去相反,从句用过去完成时.if i had won that game.
如果(过去的某一时间)我赢了那比赛,我就怎样怎样.
表示和将来相反,从句用
1.过去时
2.should+do
3.were to do
这三者只有细微差别.
If you succeeded,everything would be all right.
=If you should succeed,everything would be all right.
=If you were to succeed,everything would be all right.
翻译:如果你将来会成功的话,一切都会OK的.
ALL.

判断是真实条件句还是非真实条件句。只有在非真实条件句中才使用虚拟语气。在as if / as though 从句中,表示和现在事实相反或对现在情况有所怀疑,用

过去:从句 had done 主句 would/should/could/might have done
现在:从句did/were 主句would/should/could/might do
将来:从句were to do/should do/did 主句 would/should/could/might do
把它背下来 一切ok!
