同学好~

这个词组的位置取决于它连接的是句子的哪两个成分，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.

这里在not only ..but also...面前，too many hats 应该是一体的，如果分开定语too many就失去了活性，所以不能分开的哈~

希望帮到同学~
