　　三、几种特殊的虚拟条件从句

　　1．省略if形式的虚拟语气

　　在if虚拟条件句中，若省略if，则将should，were，had前置，构成主谓倒装句式。

　　Should he agree to go there(＝If he should agree to go there)，we would send him there.

　　要是他答应去的话，我们就派他去。

　　Were she my daughter(＝If she were my daughter)，I wouldn't allow her to study abroad.

　　如果她是我的女儿的话，我就不让她出国学习了。

　　Had I worked harder(＝If I had worked harder)，I would have succeeded.

　　如果我当时努力学习的话，我就会成功的。

　　2．混合虚拟语气

　　若主句和从句所表示的时间不一致，就构成了混合虚拟语气或错综虚拟语气，此时，主句和从句的时态形式根据实际的时间概念来定。

　　If she had followed the doctor's words，she would feel better now.

　　如果当初她听从了医生的建议，现在就会好多了。

　　If he were free today，we would have sent him to Beijing.

　　如果他今天有空的话，我们就会已经派他去北京了。

　　3．含蓄虚拟语气

　　有时候假设的条件不是通过条件从句表达，而是隐含在某些介词短语中，如without...，but for...等；某些副词或连词中，如otherwise，however，or，but等。

　　Without music(＝If there were no music)，the world would be dull.

　　世界若无音乐将会很枯燥。

　　But for your help(＝If there had not been your help)，I would not have succeeded in the experiment.

　　如果没有你的帮助，我的实验就不会成功。

I'm really very busy，otherwise(＝if I were not so busy) I would certainly go there with you.
