如 Not only…but also, Hardly/Scarcely…when, No sooner… than等，前倒后不倒。例如：
Not only did he refuse the gift, he also severely criticized the sender. 他没有收下礼物，还狠狠批评了送礼的人。
Hardly had she gone out when a student came to visit her. 她刚出门，就有个学生来访。
No sooner had she gone out than a student came to visit her. 她刚出门，就有个学生来访。
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
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，如Not only you but also I am fond of music。
