No sooner had they reached the station ----the train left.

倒装句,原句为They had no sooner reached the station than the train left。当他们刚赶到车站,火车就开了。No sooner。。。than。。。放句首时要倒装。 再问： 可不可以用When。。。。。。翻译这个句子 再答： 用when的话，就是hardly。。。when。。。的搭配了，意思差不多，搭配不一样而已。 Hardly had they reached the station when the train left。 原句为 They had hardly reached the station when the train left。
