as well as的用法

常用結構如下：名詞/形容詞/副詞+as well as+名詞/形容詞/副詞

從句+as well as+動詞ing

As well as+動詞ing+從句

1. as well as = not only……but also,意為“不但……而且……，既……又……”，如：

He's got a car as well as a motorbike.他不僅得到了一輛車還得到了一輛摩托車。

She's clever as well as beautiful。她既聰明又漂亮。

2.as well as 后面接動詞，要用動詞ing形式，如：

Smoking is dangerous,as well as making you smell bad.吸煙很危險，而且使你氣味難聞。

As well as breaking his leg,he hurt his arm.他不僅摔了腿，還傷了胳膊。（NOT As well as he broke his leg……）

區別下面兩個句子的不同：

She sings as well as playing the piano.(=She not only plays,but also sings.)她既會唱歌也會彈鋼琴。

She sings as well as she plays the piano.(=Her singing is as good as her playing)她的唱歌像和彈鋼琴一樣好。

如果 as well as用作連詞引出比較從句，其義為“和…一樣好”。

注：as well as后接動詞用動名詞的情況主要見于主句謂語為簡單時態(即一般現在時和一般過去時)的時候。
