as good as與as well as的用法區(qū)別

1. 用于本義，兩者意為“與……一樣好”，但 good 是形容詞，而 well 是副詞。如：

他說(shuō)英語(yǔ)說(shuō)得跟她一樣好。

正：He speaks English as well as her.

正：His English is as good as hers.

2. 用于引申義，兩者的意思很不相同：

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

He as good as said I’m a liar. 他無(wú)異于說(shuō)我撒謊。

We’re as good as ruined. 我們差不多完蛋了。

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

You’ll find that she’s as good as her word. 你能了解到她這個(gè)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(huì)說(shuō)英語(yǔ)和法語(yǔ)，而且會(huì)說(shuō)西班牙語(yǔ)。

該結(jié)構(gòu)強(qiáng)調(diào)的重點(diǎn)是在前面一個(gè)詞（體會(huì)以上例句的譯文）。如：

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

該結(jié)構(gòu)連接兩個(gè)成分作主語(yǔ)時(shí)，其后謂語(yǔ)通常與前面一個(gè)主語(yǔ)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(dòng)詞連用，動(dòng)詞通常要用動(dòng)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(huì)彈鋼琴，而且會(huì)唱歌。

有時(shí)也可與主句動(dòng)詞的形式一致或用動(dòng)詞原形（但均不如用動(dòng)名詞常見(jiàn)）。如：

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