请帮忙举例解释hardly when的用法

hardly when ＝刚一...就...
举几个例句给你就容易理解用法：

Hardly had the foot ball game begun when it started raining.
足球比赛才刚刚开始就下起雨来。

Hardly have I get home when the telephone rings.
我一到家电话铃就响了。

◆另外，hardly 也可以以 scarcely 来替代。
例如：
Hardly/Scarcely had we arrived, when it began to rain.
我们刚一到就下起雨来了

Hardly had he arrived when she started complaining.
他刚一到, 她就开始抱怨起来。
