also, too, either, as well的区别

also, too, either, as well的区别

这四个副词均可表示“也”，区别如下：

1.too 和as well 多用于口语中，语气较轻，通常用于肯定句或疑问句，一般不用于否定句，且通常放在句末。如：

I like you too [as well]. 我也喜欢你。

Are they coming too [as well]? 他们也来吗?

too 有时也紧跟在主语后(注：as well 不这样用)，此用法较正式。如：

I, too, know where he lives. 我也知道他住在什么地方。

在Me too, You too 这类简略答语中，通常不用as well, also。如：

A：I’m tired. 我累了。

B：Me too. 我也是。

as well

意为“也，又，而且”，意思等同于too，also，但as well只能置于句末。

He speaks English and Spanish as well.

他既能说英语, 也能说西班牙语。

There may be travel expense, as well.

可能还有旅途费用。

Are they coming as well?

他们也来吗？as well

也, 还有

He speaks English and Spanish as well.

他既能说英语, 也能说西班牙语。

2.also 比too 和as well 正式，一般也不用于否定句，它在句中的位置通常是紧靠动词，即放在行为动词之前，特殊动词之后。有时为了强调也放在句末(但不常见)。如：He also came. / He came also. 他也来了。

She is young and beautiful，and also rich. 她年轻漂亮，而且有钱。

also 有时用于句首(其后通常有逗号)，相当于连词and。如：

Also，his mother was dead. 再说，他母亲又过世了。

3.either(也)通常只用于否定句，且要放在句末。如：

I don’t know, either. 我也不知道。

He hasn’t finished it，either. 他也还没有做完。

注：有时在肯定句之后跟一个否定句，可能用too，also。如：

He came, but she didn’t also came. 他来了，但她没有也一起来。

He went to Washington, but not to New York too. 他去了华盛顿，但并不是也去了纽约。

比较：

He didn’t buy a computer, and she didn’t either. 他没有买电脑，她也没有买。

He bought a computer, but she didn’t too. 他买了台电脑，但她没有也买台电脑。

as well相当于too和also，但要注意与too，also，either的区别。

as well通常用于肯定句中，一般置于句尾，不能用逗号与其前面的词隔开;

too通常用于肯定句中，一般置于句尾，且通常用逗号与其前面的词隔开;

also通常用于肯定句中，一般置于句中;

either通常用于否定句或疑问句中，一般置于句尾。如:

He is a pianist，and he is a singer as well.

He is a pianist，and he is a singer，too.

He is a pianist，and he is also a singer.

He isn’t a pianist，and he isn’t a singer either.

联想拓展

as well as意为“不仅……而且……，既……又……；除了……之外，还有……；和……一样好”。

as well as作介词用时，意思等同于besides,意为“除……之外”，后跟动词时通常用v.-ing 形式。

as well as连接主语时，谓语动词的单复数形式取决于as well as前面主语的单复数形式。

may/might as well do意为“不妨……；还是……好”。

Are you coming as well?

=Are you coming, too?

=Are you also coming?你也来吗？
