G31-02 not only but also文法怎麼用？一次搞懂not only A but also B完整用法及倒裝！
文章編號：G31-02
not only A but also B 「不只A還有B」這句型算是很多人在高中學習英文的歲月裡都能琅琅上口的用法。但not only but also到底怎麼用呢？它不單單只是種對等連接詞，同時也常常以倒裝的形式出現，而相信許多人都想了解not only but also該如何換成倒裝句呢？本文就來一次講清楚說明白囉～
一、 A, B須為對等結構
not only A but also B被視為一種對等連結詞，何謂「對等」？意思是說，這句型連結起來的A和B需為一樣的文法結構，例如同為動詞，同為名詞，同為形容詞，或同為片語等。
E.g.1: She not only completed her project ahead of schedule but also exceeded expectations with its quality.
「她不只提早完成計畫，品質上還超乎期待。」(A, B皆為動詞）
E.g.2: She enjoys not only literature but also art.
「她不止喜歡文學，也喜歡藝術。」（A, B皆為名詞）
E.g.3: The movie was not only entertaining but also thought-provoking.
「這電影不但娛樂性足，還發人深省。」(A, B皆為形容詞）
E.g.4: He enjoys hiking not only in the mountains but also along the coast.
「他健行不只喜歡在山裡面，也喜歡沿著海岸。」(A, B皆為介系詞開頭的片語）

小提醒：A, B的「對等」，除了文法結構要一樣之外，其實意思也要有「一致性」。例如A, B都一致表達正面的意思，或是負面的意思。有些英文學習者在使用這個句型造句時，會出現文法結構雖然一樣，但意思很詭異的情況... |
二、 not only A but also B的小變形
-
這句型的also直接省略，
-
這句型的also也可以省略後，後面加上too或as well.
-
only可以換成just, simply或merely
換言之，用上面的例句1為例，可以改寫為...
E.g.: She not only/ just/ simply/ merely completed her project ahead of schedule but (also) exceeded expectations with its quality.
= She not only/ just/ simply/ merely completed her project ahead of schedule but exceeded expectations with its quality too/ as well.
三、 not only A but also B當主詞時，後面的動詞要視B而定
這原理是因為這句型的訊息重點強調在B, 故句子動詞要視B而定。
E.g.1: Not only perseverance but also dedication is crucial for success in this endeavor.
「在這項努力當中，不只是毅力還有全心付出是成功的關鍵。」
(這邊的B是dedication, 單數名詞，故整句話的動詞要取單數is, 不會是複數are)
E.g.2: Not only Thomas but also his sisters are dedicated to helping the poor.
「不只湯瑪斯還有他的姐妹們都致力於幫助窮人。」
(這邊的B是his sisters, 複數名詞，故整句話的動詞要取複數動詞are, 不是單數is)
|
比較1：用A(,) as well as B/ A(,) together with B/ A(,) along with B這三種句型當主詞用時，因為訊息重點強調在A, 故整句話的動詞要視A而定唷～用上面的例句2來改寫一下
|
|
比較2: both A and B這句型當主詞用時，因為A,B同等重要，故這主詞要兩個都算進去，那一定是個複數主詞，當然就要接複數動詞囉～一樣以上面的例句2來改寫
|
四、not only擺句首時要倒裝
如果not only A but also B不是用來當整句話的主詞時，其句中的not only可移到句首，但其傳達的A訊息要改成倒裝句來表達，也就是改成疑問句的樣子。直接把第一組的例句們拿來改成倒裝句觀摩一下吧～
(注意：but後面的部分可以照抄，也可以加字而自成一個完整的句子）
