高中英语语法讲解:虚拟语气if倒装句

  三、省略连词if 采用倒装的非真实条件句

  在书面语中,条件从句可以不用连词if, 而将谓语中的过去式were,had或should等移至主语之前,构成倒装。

  例:Were you in my position, you would do the same.

  假如你处在我的地位,你也会这样干的。

  例:Had he come earlier, he would have met her.

  要是他早点来的话,他就会见到她了。

  四、虚拟语气在储蓄条件句中的应用

  非真实条件句中的条件从句有时不表示出来,只暗含在短语或上下文中,这种句子叫做储蓄条件句。常见的有but,for ,without等引导的短语,以及or, or else, otherwise, but 等后面的分句。

  例:But for your help we couldn’t have succeeded in the experiment.

  如果没有你的帮助,我们的实验室是不会成功的。

  例:We could have done better under more favourable conditions.

  在更有利的条件下,我们能够做得更好些。
