（3）否定副词从句：

② 正确的倒装结构

（1）主语+be动词→be动词+主语

He is never interested in sports.

Never he is interested in sports.

Never is he interested in sports.

他对体育运动从不感兴趣。

（2）主语+情态动词或will，shall等→情态动词或will，shall等+主语

He can by no means handle it.

（3）主语+动词→do/does/did+主语+动词原形

提示

①not only…but also（不仅……而且）连接两个对等的从句时，not only后用倒装，但but also后的句子不倒装，also应置于句中或省略，或不用also，而在句尾加as well。

②not同neither，nor连用。

他不会唱歌，我也不会。

=He can't sing，and neither can I.

③no sooner…than（一……就……）结构要倒装。
