同学你好！
需要明确的是倒装与不倒装，意思都是一样的哦。
1. 连接二个分句（并列句），且not only位于第一分句主语之前，则该分句要部分倒装；后一个分句，即 but 后面不用倒装。
Not only does she speak English but also French.
2. 如果not only不是位于第一分句主语之前，前后两个分句的主语相同，可以改为并列二个谓语，此时则不倒装。
Not only had the poor man been arrested, but he had been sent to prison as well.
= The poor man had not only been arrested but sent to prison as well.
3. 如果 Not only ... but ... 连接两个主语，不能使用倒装。
Not only the teachers but also the students love their school very much.
(此句中的 the teachers 和 the students 是主语。不能说：Not only do the teachers but also the students love their school very much.）
