            否定副词位于句首时的倒装
        　　在正式文体中，never, seldom, rarely, little, hardly, scarcely, no sooner, no longer, nowhere 等含有否定意义的副词若位于句首，则其后要用部分倒装：
        　　I shall never forgive him. / Never shall I forgive him. 我永远不会宽恕他。
        　　He seldom goes out for dinner. / Seldom does he go out for dinner.
        　　他很少出去吃饭。
        　　She hardly has time to listen to music. / Hardly does she have time to listen to music. 她几乎没时间听音乐。
        　　He little realizes how important this meeting is. / Little does he realize how important this meeting is. 他不甚明白这个会议的重要性。
        　　We had no sooner reached the airport than the plane took off. / No sooner had we reached the airport than the plane took off. 我们刚到机场,飞机就起飞了。
        　　【注意】
        　　(1) 对于not…until句型，当not until…位于句首时，其后的主句要用倒装语序：
        　　He didn’t leave the room until the rain stopped. / Not until the rain stopped did he leave the room. 雨停了之后他才离开这房间。
        　　(2) 某些起副词作用的介词短语，由于含有否定词，若位于句首，其后要用部分倒装：
        　　On no accounts must this switch be touched. 这个开关是绝不能触摸的。
        　　In [Under] no circumstances will I lend money to him.无论如何我也不会再借钱给他了。
        　　但是，in no time(立即，马上)位于句首时，其后无需用倒装语序：
        　　In no time he worked out the problem. 他马上就算出了那道题。
