25. hardly … when … “一 … 就 …”
通常when 前面的动词用过去完成时，后面的用过去时；
Hardly had we begun when we were told to stop. 我们刚开始就被叫停。
当否定副词hardly放在句首时，主句的主谓用倒装语序，类似的结构还有No sooner … than … ； Scarcely … when … 等，如：
Scarcely had we gone out when it began to snow. 我们刚一出来就下起雪来了。
No sooner had she reached the station than the train left. 她刚到车站火车就开走了。
