❝ not only ... but also 是各類英文測驗中最常考到的相關連接詞，而測試重點一般都在看考生是否能確實了解由 not only 和 but also 所引導的結構必須完全對等。❞
請看例句：
- Not only you but also I was surprised to see him there.（不只是你，我也非常驚訝在那兒看到他。）
- They not only made the rules but also enforced them.（他們不僅訂定那些規則，而且還嚴格執行。）
- Not only did he invite us to his party, but he also gave us gifts.（他不但邀請我們去參加他的派對，而且還給我們禮物。）
● 秒懂關鍵
❶由 not only 與 but also 所引導的兩個項目雖然在文法上必須對等，但是在語意上卻較著重第二項，因此若用來作為主詞，動詞必須與第二個名詞一致，如 a 句所示。
❷若 not only 和 but also 引導的是子句時，記得句首由 Not only 所引導的子句必須採倒裝形式，而第二個子句則應由簡單連接詞 but 來引導，副詞 also 必須置於靠近動詞的位置，不可置於主詞之前，如 c 句所示。
❸因為 also 不是連接詞，所以可以省略不用；換言之，a、b、c 亦可寫成：
- Not only you but I was surprised to see him there.
- They not only made the rules but enforced them.
- Not only did he invite us to his party, but he gave us gifts.
