2016年中考英语词组辨析：as soon as/ hardly…when/ no sooner…than

　　Ⅰ. 三者在意义上基本相同，都有“一……就……”，“刚……就……”，但它们各有其特点。

　　Ⅱ. as soon as 最为普通，位置灵活，可在主句前，也可在其后。且可用作多种时态。如：

　　① As soon as I went in , Kate let out a cry of surprise. 我一进去，凯特就惊讶地叫了一声。

　　② I’ll tell him as soon as he comes back.

　　Ⅲ. hardly… when…的主句通常 用过去完成时，从句用一般过去时，when有时还可换成before.如：

　　① He had hardly finished his homework when the light went out. 他刚写完作业灯就灭了。

　　② Hardly had I come back when they began quarrelling.我一回来他们就开始吵了起来。(hardly 提前时，句子需要倒装。)

　　Ⅳ. no sooner…than…句型中， no sooner一般只置于句首，所以主句有倒装形式。如：

　　No sooner had I known the news than I telephoned my mother. 我刚知道这个消息就打电话告诉了妈妈。
