not only ,but also的用法是什么

1. not only … but also 应连接两个相对称的并列成分。例如：

Not only Mr Lin but also his son joined the Party two years ago. （连接两个主语）

I not only play tennis but also practise shooting. （连接两个谓语动词）

He plays not only the piano but also the violin. （连接两个宾语）

They speak English not only in class but also in the dormitory. （连接两个地点状语）

注 1 ： She not only sings well but also dances beautifully. = She doesn't only sing well but also dances beautifully.

注 2 ：句子 He not only plays the piano but also the violin 不是好的文体，因为 but also 之后的成分与 not only 之后的成分不对称。

2. not only … but also 连接两个分句，并且 not only 位于句首时，第一个分句中的主语和谓语要部分倒装。例如：

Not only does the sun give us light but also it gives us heat.

Not only did he speak English correctly， but also he speaks it fluently.

Not only is this young man clever but also he is hardworking.

3. not only … but also 不能用在否定句中。例如：

误： Th
