as well 与
as well as的用法区别
一、as well 用法：
1、as well常用作状语，作“又；也”解，相当于too或also，常位于句末，无须用逗号与句子分开。如：
I am going to London and my sister is going as well（＝going，too）.
我要到伦敦去，我妹妹也要去。
I not only play the guitar，I sing as well（＝I also sing ）.
我不但弹吉他，而且还演唱。
2、as well 在口语中也可用于句中，作“也好，也行”或“倒不如”解，用来缓和语气。如：
You may as well go、
你去也好。
The weather was so bad that we might（just）as well have stayed at home.
天气太坏了，早知道如此，倒不如呆在家里为好。
3、as well 可以直接用于just后，用作应答语（可视为It's just as well、的省略），作“幸亏，幸而；无妨；没关系”解。如：
—We were too late to see the film.
我们去得太晚了，没有看上电影。
—Just as well、I hear it isn't very good.
不必遗憾，我听说电影也不怎么样。
二、as well as 用法
一、分清本义与引申义
1．用于本义
as well as用于本义，可视为as…as结构与well的自然搭配，其意为“与……一样好”，在否定句中可用notso well as代替not as well as。如：
He speaks English as well asshe．他说英语说得跟她一样好。
She plays every bit as well asthe men．她打得一点不比男人们差。
He doesn’t play half so well ashis sister．他演奏的水平不及他姐姐的一半。
He sings as well as．if not bet-ter than，Mary．他要是唱歌不比玛丽唱得更好，但至少也是一样好。
2．用于引申义
用于引申义，表示“不但……而且”“既是……也是”“而且”“还”。如：
He grows flowers aS well asvegetables．他既种菜也种花。
She shares(in)my troubles aswell as my joys．她与我同甘共苦。
They have a flat in town as wellas in the Country．他们在城里有一套公寓，在乡村还有一所房子。
注：有时还可译为“除……之外，还”，与besides，in addition to的用法相似。如：
As well aS learning to swim hehas been taking Spanish lessons thissummer．今年夏天，他除了学习游泳外，他还在上
西班牙语课。
二、弄清强调重点
A as well as B这一结构强调的重点是A不是B，即A as well as B=not only B but also A,注意体会以下例句的译文：
She is clever as well as beautiful．她不但漂亮，而且聪明。
He speaks Spanish as well as English and French．他不仅会说英语和法语，而且会说西班牙语。
Actors have to learn their cues as well as their own lines．演员不仅要记住台词，还要记住其他演员的暗示。
三、把握主谓一致
当as well as连接两个成分作主语时，其后谓语的单复数形式通常要与前面一个主语保持一致。如：
Tom as well as his parents is going to London．汤姆和他的父母要去伦敦。
The captain，as well as the other players，was tired．队长和其他队员都累了。
但是，有时即使as well as前面一个成分为单数，其后的谓语也可能用复数，尤其是当as well as后面一个成分比较长且该结构没有用逗号隔开时。如：
His appearance as well as his strange way of talking make me suspicious．他的外表以及他那奇怪的谈吐引起我的怀疑。
四、牢记后续动词的形式
as well as后接动词到底该用什么形式，这是一比较复杂的问题，归纳起来有以下几点值得注意：
1．as well as通常被视为介词，所以后接动词时，一般用
动名词形式。如：
He sings as well as playing the piano．他不但会弹钢琴，而且会唱歌。
As well as breaking his leg，he hurt his arm．他不但摔断了腿，而且还伤了胳膊。
Smoking is dangerous，as well as making you smell bad．吸烟不仅使你身上有气味，而且危险。
She is a talented musician as well being a photographer．她不但是摄影师，而且还是个天才的音乐家。
注：as well as后接动词用动名词的情况主要见于主句谓语为简单时态(即
一般现在时和一般过去时)的场合。
2．如果主句谓语为复合时态(即其中含有
情态动词或助动词)，则as well as后的动词通常要与情态动词或助动词后的动词形式保持一致。如：
Students shouId pursue their own interests．as Wen as do their school work．学生不仅应该要做好家庭作业，而且还要有自己的兴趣。
I have to feed the horses as well as look after the children．我不但要照顾孩子们，而且还要喂那些马。
3．如果as Well as是连接两个
不定式，则其后用不带to的不定式。如：
A museum should aim to entertain as well as educate．博物馆不仅要具有教育性还且还要具有娱乐性。
We cannot expect her to do the homework as wen as look after the chil．dren．我们不能指望她既做作业又照看孩子。
4．当as well as用于句首时，其后习惯上要接动名词。如：
As well as eating a seven-course meal，they drank three bottles of wine．除吃了一顿有七道菜的饭之外，他们还喝了三瓶酒。
As well as walking，he likes fishing and shooting．他除散步之外还喜欢钓鱼和打猎。
As well as visiting
Niagara Falls，we spent a day in Toronto．我们参观了
尼亚加拉瀑布，而且还在多伦多玩了一天。
As well as getting on everybody’s nerves．he’s got a habit of borrowingmoney and forgetting to pay it back．他使得人人都感到心烦，此外，他还有个习惯，就是借了钱就忘了还。
注：as well as有时也被视为准
并列连词，后接的动词可以与主句
谓语动词形式一致(但这种情形远不如用后接动名词普遍）。
