no sooner than的倒装句（no sooner than）

1、No sooner . than=scarely . when = hardly . when 刚. 就.一.就.这三个短语与as soon as 的中文意思类似。

2、只不过，as soon as 要主将从现前三个短语要与过去完成时态连用。

3、例如：I will let you know as soon as he comes.( 主将从现）I had no sooner come back than it began to rain.=I had hardly come back when it began to rain.=I had scarely come back when it began to rain.我刚回来就开始下雨了。

4、（与过完连用）此外，no sooner, hardly, scarely 放于句首，引起倒装。

5、上面的例句可以改成：No sooner had I come back than it began to rain.=Hardly had I come back when it began to rain=Scarely had I come back when it began to rain.
