as well與as well as只有一詞之差，但意義和用法卻相差甚遠(yuǎn)。

一、as well 用法：

1、as well常用作狀語，作“又；也”解，相當(dāng)于too或also，常位于句末，無須用逗號與句子分開。如：

China is a socialist country, and a developing country as well.

中國是一個(gè)社會主義國家，也是一個(gè)發(fā)展 中國家。

I am going to London and my sister is going as well（＝going，too）.

我要到倫敦去，我妹妹也要去。

I not only play the guitar，I sing as well（＝I also sing ）.

我不但彈吉他，而且還演唱。

2、as well 在口語中也可用于句中，作“也好，也行”或“倒不如”“最好”解，用來緩和語氣。如：

If you find it unworkable, we may as well call the deal off.

如果你覺得價(jià)格不可行，我們最好取消這筆交易。

You may as well go、

你去也好。

The weather was so bad that we might（just）as well have stayed at home.

天氣太壞了，早知道如此，倒不如呆在家里為好。

3、as well 可以直接用于just后，用作應(yīng)答語（可視為It's just as well、的省略），作“幸虧，幸而；無妨；沒關(guān)系”解。如：

—We were too late to see the film.

我們?nèi)サ锰砹?，沒有看上電影。

—Just as well、I hear it isn't very good.

不必遺憾，我聽說電影也不怎么樣。

二、as well as 用法

1、as well as常用來連接兩個(gè)并列的成分，作“也，還”解。它強(qiáng)調(diào)的是前一項(xiàng)，后一項(xiàng)只是順便提及。因此連接并列主語時(shí)，謂語動詞與前一項(xiàng)一致；而用not only ...but also...連接時(shí)，謂語動詞與后一項(xiàng)一致。如：

Your wife as well as you is friendly to me.

不僅你而且你的妻子也對我很友好。

（＝Not only you but also your wife is friendly to me、）

Electric energy can be changed into light energy as well as into sound energy.

電能既可以被轉(zhuǎn)變成聲能，又可以被轉(zhuǎn)變成光能。

2、as well as 用來表示同級比較，指“一樣好”。如：

You look as well as you did ten years ago.

你的身體看起來還和十年前一樣好。

He plays the guitar as well as you.

他的吉他彈得和你一樣好。
