hardly.when.和no sooner.than 这两个句型有什么区别?

意思基本相同：都是“一...就...”
I had hardly got home when it began to rain.
我刚一到家,就下雨了.=Hardly had I got home when it began to rain.
No sooner had we got to the station than the train left.
我们刚到车站,火车就走了.
Hardly had we begun when we were told to stop.
我们刚开始就被叫停.
hardly…when和no sooner…than的意义相当于as soon as,但只表示过去发生的事情,主句为过去完成时,从句为过去时,如hardly或no sooner位于句首时语气强,而且主句的谓语要用部分倒装.
这两个句型在做题时注意三点：1.搭配不同
2.时态
3.倒装
