no sooner than倒裝句用法

No sooner... than...，"一...就..."， 引導時間狀語從句。主句用過去完成時，that後面的從句用一般過去時。

即:主語+had no sooner done+than 主語 did

I had no sooner raced home， than it began to rain.

No sooner放句首表示強調，主句要倒裝。

No sooner had I reached home， than it began to rain.

與這個短語類似的，還有...

We had hardly got there when it began to rain.

Hardly had we got there when it began to rain.
