no sooner... than... "一...就..."
引导时间状语从句,主句用过去完成时,"than"后面的从句用一般过去时.(从这里可以知道,no sooner后面是主句;than后面是从句)
例:
1
I had no sooner reached home than it began to rain.
我一到家天就下起雨来
2
No sooner ...than...
常放在句首,表示强调.这时主句要倒装.
例:No sooner had I reached home than it began to rain.
3
I had no sooner arrived home than the bell rung.我一到家铃就响起来了
4
She had no sooner finished her work than it began to rain.
5
We had no sooner arrived at the www.souquanme.compark than it begab to rain.
