Not only …but also是英語學習中常見的短語，意為“不僅…而且”可以連接并列的短語，也可連接并列的句子，當它連接兩個名詞或代詞作主語時，謂語動詞的單復數問題遵循就近原則：即離謂語動詞最近的那個主語的單復數來決定謂語動詞的單復數形式。
not only but also用法
1.not only … but also應連接兩個相對稱的并列成分。例如：
Not only Mr Lin but also his son joined the Party two years ago.（連接兩個主語）
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.（連接兩個地點狀語）
注1： She not only sings well but also dances beautifully. = She doesn't only sing well but also dances beautifully.
注2：句子 He not only plays the piano but also the violin 不是好的文體，因為 but also 之后的成分與 not only 之后的成分不對稱。
2.not only…but also連接兩個分句，并且not only位于句首時，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 did he speak English correctly， but also he speaks it fluently.
Not only is this young man clever but also he is hardworking.
not only but also什么意思
不但…而且…的意思。
Not only … but also是英語中比較常見的一個關聯詞組，用于連接兩個表示并列關系的成分，著重強調后者。它的意思是"不僅。而且…"；其中的also有時可以省略。
Not only … but also中的also可以省略。有人認為該句型所連接的第二部分最高級形容詞或它所表示的范圍、程度、影響等超過第一部分時，常將also省略。
not only … but also句型一般只省略also，但在連接句子時，有時也可見到省略but甚至but also的情形。
not only … but also的形式比較固定，但也會出現but與also被分隔開來的情形。
not only but also是就近原則嗎
not only……but also……有就近原則。當not only……but also……連接兩個主語時，謂語動詞采取就近一致原則，即謂語動詞要和與其最近的主語保持人稱和數的一致。
1.not only… but also可以連接兩個主語、賓語、謂語動詞、表語或狀語等。它連接的兩個成分往往是對稱的。
Not only Jim but also his boss is going to attend the meeting. （連接兩個主語，注意謂語動詞采取就近原則）
Timmy likes eating not only chicken but also fish.（連接兩個賓語）
He not only read the book, but also remembered what he had read.（連接謂語動詞）
Allen is not only an artist but also a great basketball player.（連接兩個表語）
2.not only… but also也可以寫作not only… but…as wellHe not only read the book, but remembered what he had read as well.
3.not only… but also…里but和also可以分開
Not only will you enjoy the art works but you can also exchange ideas with artists.（注意，不把also放在can前面）
4.當not only放在句子最開頭時，not only引導的句子倒裝，but also的句子不倒裝，正常語序。
Not only do the nurses want a pay increase, but also they want reduced hours.
