as good as與as well as的用法區(qū)別

1. 用於本義，兩者意爲(wèi)“與……一樣好”，但 good 是形容詞，而 well 是副詞。如：

他說英語說得跟她一樣好。

正：He speaks English as well as her.

正：His English is as good as hers.

2. 用於引申義，兩者的意思很不相同：

(1) as good as 意爲(wèi)“幾乎”“差不多”(=almost)。如：

He as good as said I’m a liar. 他無異於說我撒謊。

We’re as good as ruined. 我們差不多完蛋了。

習(xí)語be as good as one’s word意思是“說話算數(shù)”。如：

You’ll find that she’s as good as her word. 你能了解到她這個人很講信用。

(2) as well as 表示“而且”。如：

She’s clever as well as beautiful. 她不但漂亮，而且聰明。

He speaks Spanish as well as English and French. 他不僅會說英語和法語，而且會說西班牙語。

該結(jié)搆強(qiáng)調(diào)的重點是在前麪一個詞（躰會以上例句的譯文）。如：

A as well as B=not only B but also A

該結(jié)搆連接兩個成分作主語時，其後謂語通常與前麪一個主語保持一致。如：

Mary as well as her friends is going to Paris. 瑪麗和她的朋友要去巴黎。

與動詞連用，動詞通常要用動名詞。如：

As well as breaking his leg, he hurt his arm. 他不但摔斷了腿，而且還傷了胳膊。

He sings as well as playing the piano. 他不但會彈鋼琴，而且會唱歌。

有時也可與主句動詞的形式一致或用動詞原形（但均不如用動名詞常見）。如：

As well as eating [ate, eat] a seven-course meal, they drank three bottles of wine. 除喫了一頓有7道菜的飯之外，他們還喝了3瓶酒。
