◇ Inversion with Negative Adverbials
否定副詞倒裝句
倒裝句指的是順序上做了改變，我們都知道文法句子中主詞會出現在前面，然後是動詞，但今天我們要看的情形正好相反。固定用法 Not only... but also... 就是倒裝句型，表示「不只...而且...」。一般來說，當遇到以否定為開頭的句子，就會有倒裝的出現，例如例句 Not only is Kirkland Signature extra virgin olive oil priced fairly low, but it also gets rave reviews for its taste. 因為 Not only 開頭，因此前半句的 be 動詞 is 在主詞前面，這就是倒裝。
Example：
1. Not only is he smart, but he is also diligent.
他不只聰明，還很用功。
2. Not only did the dog bark at him, but it also bit him.
那隻狗不只對他吠了，還咬了他。
3. Not only did Janet come to today's meeting late, but she also did not prepare any material for our client.
Janet 不只遲到了今天的會議，她甚至沒有為我們的客戶準備任何資料。
