英语倒装句用法归纳

6.虚拟条件句的省略与倒装

当if引导的虚拟条件从句中含有had,were,should等时，如将if省略，则要将had,were,should等移到主语前，构成倒装句：

Had you come yesterday, you would have seenhim.若你昨天来，你就会见到他了。

Should you require anything give me a ring.如果需要什么，可以给我打电话。

Were it not for your help, I would still be homeless.要不是你帮助，我会仍然无家可归。

【注意】省略if后提前的had不一定是助动词：

Had I money, I would buy it.假若我有钱，我就会买它。
