　　典型例题
　　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. 以具有否定意义的副词放在句首时，一般采用倒装句（谓语前置）。这类表示否定意义的词有never, seldom, scarcely, little, few, not, hardly, 以及not onlybut （also）, no soonerthan, hardly when scarcely when　等等。

　　注意：只有当Not only but also连接两个分句时，才在第一个分句用倒装结构。如果置于句首的Not only but also仅连接两个并列词语，不可用倒装结构。
　　Not only you but also I am fond of music.
