北京新東方酷學酷玩英語夏令營：

以否定詞開頭作部分倒裝
 
　 如 not only…but also, hardly/scarcely…when, no sooner… than
　 not only did he refuse the gift, he also severely criticized the sender.
　 hardly had she gone out when a student came to visit her.
　 no sooner had she gone out than a student came to visit her.

典型例題
no sooner___ than it began to rain heavily.
a. the game began　　　　　 b.　has the game begun
c. did the game begin　　　 d.　had the game begun
答案d. 以具有否定意義的副詞放在句首時，一般采用倒裝句(謂語前置)。這類表示否定意義的詞有never, seldom, scarcely, little, few, not, hardly, 以及not only…but (also), no sooner…than, hardly… when scarcely… when　等等。

注意：只有當not only… but also連接兩個分句時，才在第一個分句用倒裝結構。如果置于句首的not only… but also僅連接兩個并列詞語，不可用倒裝結構。
　 not only you but also i am fond of music.
