Question

Hardly had he arrived when she started complaining.为什么had在主语he的前面呢

Answer 1

倒装句的一种形式 hardly,in no way,little,scarcely,seldom,never,no more,no longer,not,not only,no sooner,not only … (but also),not until… 等具有否定意义的词或词组位于句首,句子用部分倒装.
再比如
1.No sooner had I got home than it began to rain.
我刚到家就下起了雨.
2.Seldom do I go to work by bus.
我很少乘公共汽车上班.
其中英文倒装句讲的很全面
