? ??否定副詞位于句首時的倒裝

　　在正式文體中，never, seldom, rarely, little, hardly, scarcely, no sooner, no longer, nowhere 等含有否定意義的副詞若位于句首，則其后要用部分倒裝：

　　I shall never forgive him. / Never shall I forgive him. 我永遠不會寬恕他。

　　He seldom goes out for dinner. / Seldom does he go out for dinner.

　　他很少出去吃飯。

　　She hardly has time to listen to music. / Hardly does she have time to listen to music. 她幾乎沒時間聽音樂。

　　He little realizes how important this meeting is. / Little does he realize how important this meeting is. 他不甚明白這個會議的重要性。

　　We had no sooner reached the airport than the plane took off. / No sooner had we reached the airport than the plane took off. 我們剛到機場,飛機就起飛了。

　　【注意】

　　(1) 對于not…until句型，當not until…位于句首時，其后的主句要用倒裝語序：

　　He didn’t leave the room until the rain stopped. / Not until the rain stopped did he leave the room. 雨停了之后他才離開這房間。

　　(2) 某些起副詞作用的介詞短語，由于含有否定詞，若位于句首，其后要用部分倒裝：

　　On no accounts must this switch be touched. 這個開關是絕不能觸摸的。

　　In [Under] no circumstances will I lend money to him.無論如何我也不會再借錢給他了。

　　但是，in no time(立即，馬上)位于句首時，其后無需用倒裝語序：

　　In no time he worked out the problem. 他馬上就算出了那道題。
