◇ Inversion with Negative Adverbials
否定副詞倒裝句
以「否定副詞」來構成倒裝句的句型有很多種，這部影片我們主要介紹的是常見的 not only...(but also)。拿例句來說， Not only can depression have you feeling down, but it can actually physically affect parts of your body other than the brain. 我們可以看到 not only 被移到句首之後，助動詞 can 與主詞 depression 的位置會「互換」，以構成所謂的「倒裝」。其他常見以此法構成倒裝的否定副詞包含 hardly、scarcely、rarely、never、seldom、only if、onloy when、under no circumstances 等等。
Example：
1. Not only did he read the book, but he also remembered all that he had read.
他不僅讀過這本書，還記得裡面所有的內容。
2. Not only did he lie, but he also stole from us.
他不只騙了我們，還偷了我們的東西。
3. Not only does she dance extraordinarily but she also sings perfectly.
她不但跳舞跳得出色，唱歌也很棒。
