no sooner than用法如下:
no sooner+事情(先发生)than+事情(后发生)
主句用过去完成时,than后面的从句用一般过去时。no sooner后面是主句 ; than后面是从句
no sooner...than 就是一个固定用法
一...就... 事情已经完成,所以必须要用过去完成时had
同学举得例子是不可以的,no sooner had rung(前面的事) than the students quieted down(后面的事).
no sooner than 的意思是:一...就...
这句话的意思是:你一到达就得考虑打包去旅行。
例如:
No sooner had I reached home than it began to rain.
我一到家就开始下雨了。
The bell had no sooner rung than the students quieted down.
铃声一响,学生们就安静下来了。
