例:No sooner had I reached home than it began to rain.2）与这个短语类似的还有hardly ...when 意思为:"还没...就..." (主句用过去完成时,从句用一般过去时)
例:We had hardly gotten there when it began to rain.我们还没到那儿,天就下起雨了.
Hardly...when...也常放在句首
例:Hardly had we gotten there when it began to rain.3）no sooner than 和hardly when以及as soon as这三个短语都有“一……就”、“刚刚……就”的意思,它们的意思非常相近,因此有时可以互换.例如：“我刚到公共汽车站,汽车就开了.”一句,就可以有如下几句译法：As soon as I got to the bus stop,the bus started.Hardly had I got to the bus stop when the bus started.No sooner had I got to the bus stop than the bus started.4） 但他们之间也有一些差异,例如,如果从两件事情的间隔时间来说,as soon as 较长,no sooner...than 居中,hardly...when 间隔时间最短.其它的一些区别见下面,请大家在运用的时候要留意.a、as soon as它的意思相当于“A事情发生以后,就做B这件事”.
这个短语用的比较常用,口语和书面语都可以.它的特点是,在句子中的位置比较灵活,而且可以用于各种时态.例如：I'll write you as soon as I get there.
我一到那儿就给你来信.（一般现在时）As soon as I went in,Katherine cried out with pleasure.
我一进门,Katherine 就高兴的叫起来.（一般过去时）I'll return the book as soon as I have read it.
我一读完就把书还回去.（现在完成时）Andrew left as soon as he had drunk his coffee.
Andrew一喝完咖啡就走了.（过去完成时）b、no sooner…than它的意思相当于“刚做完A这件事,就做B这件事”.例如：He had no sooner returned than he bought a house.
他一回来就买了一套房子.如果no sooner 位于句首,主句要用倒装结构.例如：No sooner had he arrived than he went away again.
他刚到就又走了.No sooner had the game started than it began to rain heavily.
运动会刚开始,天就下起了大雨.有一点要注意,no sooner…than 一般用来描述做过的事情,它不能用于表示将来的事.c、hardly…when...它的意思是“几乎未来得及做完A这件事,紧接着就开始B这件事.”
使用这个短语时,一般用于过去完成时；并且when有时可改用before.例如：He had hardly finished the article when the light went out.
他刚要写完文,灯就熄了.He had hardly had time to settle down when he sold the house.
他还未安顿下来,就卖掉了那所房子.另外,如果把hardly放于句首,主句要用倒装结构即谓语动词要提前.如：Hardly had I finished eating when he came in.
我刚吃完他就进来了.Hardly had she gone out when a student came to visit her.
她还没走出家门,就有一个学生来看望她.
