if条件句省略的四个条件是什么
解题思路: if条件句省略的四个条件
解题过程:
1如果if条件句中有had,should,were,有时可把if省略掉,而把had,should,were放在主语前面形成倒装句型。如: Should there be (=If there should be) a flood,what should we do?万一发生水灾我们怎么办? Were it not for their help(=If it were not for…),we couldn't have got over the difficulties. 要不是他们的帮助,这些困难我们是克服不了的。 Had they time (=If they had time),they would certainly come and help us. 如果他们有时间他们一定会来帮助我们。 The passengers would have died of cold had it not been for the driver (=if it had not been for…). 要不是司机,旅客们就会全部冻死。 Had it not been for the reservoir(=if it had not been for…),we'd never have been able to beat the drought. 如果没有水库我们就绝不能战胜这次干旱。 2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,这种句子叫做隐含条件句。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。
最终答案:略
