側(cè)重點(diǎn)不同、含義不同、用法不同。as well解析：as well一般不用否定句，通常放在句末，強(qiáng)調(diào)時(shí)可放在句中。as well as。解析：as wel。含義不通：as well釋義：也，還。as well as釋義：既…又…，除…之外（也），此外。

as well as的用法

as well as用于本義，可視為as…as結(jié)構(gòu)與well的自然搭配，其意為“與……一樣好”，在否定句中可用not so well as代替not as well as。如：

He speaks English as well as her.他說英語(yǔ)說得跟她一樣好。

用于引申義，表示“不但……而且”“既是……也是”“而且”“還”。如：

He grows flowers as well as vegetables.他既種菜也種花。

有時(shí)還可譯為“除……之外，還”，與besides， in addition to的用法相似。如：

As well as learning to swim he has been taking Spanish lessons this summer.今年夏天，他除了學(xué)習(xí)游泳外，他還在上西班牙語(yǔ)課。

當(dāng)as well as連接兩個(gè)成分作主語(yǔ)時(shí)，其后的謂語(yǔ)通常要與前面一個(gè)主語(yǔ)保持一致。如：

Tom as well as his parents is going toLondon.湯姆和他的父母要去倫敦。

as well as通常被視為介詞，所以后接動(dòng)詞時(shí)，一般用動(dòng)名詞形式。如：

He sings as well as playing the piano.他不但會(huì)彈鋼琴，而且會(huì)唱歌。

as well as后接動(dòng)詞用動(dòng)名詞的情況主要見于主句謂語(yǔ)為簡(jiǎn)單時(shí)態(tài)(即一般現(xiàn)在時(shí)和一般過去時(shí))的時(shí)候。

如果主句謂語(yǔ)為復(fù)合時(shí)態(tài)(即其中含有情態(tài)動(dòng)詞或助動(dòng)詞)，則as well as后的動(dòng)詞通常要與情態(tài)動(dòng)詞或助動(dòng)詞后的動(dòng)詞形式保持一致。如：

Students should pursue their own interests， as well as do their school work.學(xué)生不僅應(yīng)該做要好家庭作業(yè)，而且還要有自己的興趣。

如果as well as是連接兩個(gè)不定式，則其后用不帶to的不定式。如：

A museum should aim to entertain as well as educate.博物館不僅要有教育性還且還要有娛樂性。

當(dāng)as well as用于句首時(shí)，其后習(xí)慣上要接動(dòng)名詞。如：

As well as eating a seven-course meal， they drank three bottles of wine.除吃了一頓有七道菜的飯之外，他們還喝了三瓶酒。

as well as有時(shí)也被視為準(zhǔn)并列連詞，后接的動(dòng)詞可以與主句謂語(yǔ)動(dòng)詞形式一致（但這種情形遠(yuǎn)不如用后接動(dòng)名詞普遍）。如：

He publishes as well as prints his own books.他不但印刷而且還出版自己的書。

as well用法

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

(1)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。

(2)I not only play the guitar,I sing as well. 我不但彈吉他，而且還演唱。

2.as well在口語(yǔ)中也可用于句中，作“也好，也行”或“倒不如”解，用來緩和語(yǔ)氣。如：

(1)You may as well go. 你去也好。

(2)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(yǔ)(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。
