if引导状语从句怎样倒装?
1、虚拟条件句中如果谓语动词含有were, should, had这几个词，可以把were, should, had放在句首的位置，并省略掉if，这就是虚拟条件句的倒装。例如：If he had finished it yesterday, he would have handed it in then.
=Had he finished it yesterday, he would have handed it in then.
If I were there, I would help them.
=Were I there, I would help them.
If I should have 200,000 yuan, I would buy a good car.
=Should I have 200,000 yuan, I would buy a good car.
2、if引导状语从句，放在only后面。例如：
Only if you wok harder and do more practice 【can you improve 】 your Englsh.
祝你开如意！
