also, too, either 与 as well 的使用方法与辨析
also, too, either 与 as well 都表示“也”,其使用方法与不同如下:
1. too 和 as well 多用于口语中,语气较轻,一般用于一定句或疑问句,一般不需要于否定句,且一般放在句末。如:
He has to go too [as well]. 他也得去。
Are they coming too [as well]? 他们也来吗?
too 有时也紧跟在主语后,此使用方法较正式。如:
I, too, know where he lives. 我也了解他住在什么地方。
注意:在 Me too, You too这种简略答语中,一般不需要 as well或also。如:
A:I’m tired. 我累了。
B:Me too. 我也是。
2. also 比 too 和 as well 正式,一般也不需要于否定句,它在句中的地方一般是紧靠动词,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。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。
说明:also 有时用于句首,等于连词 and。如:
Also, his mother was dead. 再说,他妈妈又去世了。
3. either一般只用于否定句,且要放在句末。如:
I don’t know, either. 我也不了解。
He hasn’t finished it, either. 他也还没做完。
注意:有时在一定句之后跟一个否定句,可可以用 too,also。如:
He came, but she didn’t also came. 他来了,但她没也一块儿。
He went to
比较:
He didn’t buy a computer, and she didn’t either. 他没买电脑,她也没买。
He bought a computer, but she didn’t too. 他买了台电脑,但她没也买台电脑。
