no sooner than在句首时的用法

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 startedthan 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.
