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.
部分倒装：指将谓语的一部分如助动词或情态动词倒装至主语之前,而谓语动词无变化.如果句中的谓语没有助动词或情态动词,则需添加助动词do,does或did,并将其置于主语之前.
eg：
No sooner had I got home then it began to rain.我刚到家就下起了雨.
Seldom do I go to work by bus.我很少乘公共汽车上班.
Not until twelve o'clock did she go to bed last night .她昨晚十二点才上床睡觉.
