今天開心老師帶大家學習的是非常經典的英語表達用法：「not only…but…」相對於中文的涵義是「不但…而且…」。意義如此卻又不僅僅局限於此，如何正確使用，如何在翻譯的過程中使用到「not only…but…」，下面詳細為你解答！
一、「not only … but also」的兩種用法
1.not only … but also應連接兩個相對稱的並列成分.例如：
Not only MrLin but also his son joined the Party two years ago.(連接兩主語)
I not only play tennis but also practise shooting.(連接兩個謂語動詞)
He plays not only the piano but also the violin.(連接兩個賓語)
They speak English not only in class but also in the dormitory.(兩個地點狀語)
註：句子 He not only plays the piano but also the violin 不是好的文體,因為 but also 之後的成分與 not only 之後的成分不對稱.
2.not only …but also 連接兩個分句,並且 not only /until位於句首時,第一個分句中的主語和謂語要部分倒裝.例如：
Not only does the sun give us light but also it gives us heat.
Not only didhe speak English correctly,but also he speaks it fluently.
Not only is this young man clever but also he is hard-working.
二、如何避免使用 not only but also
寫好英文句子的核心是：先意識到自己使用了哪些濫俗搭配。
漢語：健康教育不僅可以應對青少年肥胖問題，還可以保護他們的自由
朱諾版本的翻譯：Health educationamong teenagers not only address the adolescentobesity but also protects their freedom
今天這個句子我也是用的not only but also，看到大家的句子也是清一色的not only but also, 但是有幾個娃的句子成功避免了這個比較濫俗的表達，我們來看一下：
沉迷物化生無法自拔的Diana：
Healtheducation tackles juvenile obesity, guarding teenagers' freedom.
Jasmine
Healtheducation, ensuring teenagers』 freedom, helps them stay away from obesity.
通過這兩個句子，大家看一下避免not only but also的一個用法是靈活實用伴隨狀語，這個是大家之前在群裡翻譯的時候，老師就教過的。我們今天看一下更多的避免使用not only but also的方法吧～
Plain:they were passionate lovers not only onstage but also after stage
Better:they were passionate lovers onstage and offstage
Better:they were passionate lovers onstage and off
介詞短語放在文末，言簡意賅。
Plain:outside the cinema, she lit a cigarette, not necessarily because she had adesire to smoke, but because she felt the need for warmth.
Better:outside the cinema, she lit a cigarette, as much from the need for warmth asfrom a desire to smoke
通過這個句子，我們學到一種巧妙的寫法，就是把not only but also 換成as much as 因為兩者都是表達的並列關係。From可以代替用的很俗的because.句子的靈活性就增加很多。
又比如：
在業餘時間裡，他不僅熱衷於海上衝浪，而且還熱衷於上網。
不合格: In his spare times, he not only loves surfing, but also web-surfing.
合格: in his free time, he enjoys not only surfing but also online activity.
不合格句子中，有這幾個句法錯誤：
1.業餘時間：spare time 應該是單數。
2.not only..butalso一般位於動詞後面，而且當中無需逗號。
3.前後的surfing 重複且含義不清楚。
合格範文只是合格而已，not only but also去掉後，我們來看看結果：
優秀：inhis free time, he is a surfer of both waves and the internet.
其實避免使用not only but also的句子前提是，你意識到，這個表達雖然是你最開始學的，宛如there be句型一樣印在大腦裡。但是這個表達，實在有些俗套，通過今天的講解，大家可以從語義的角度，對句子增加多樣性了。
