辨析
同近义词
as well, too,
either, also
1.also用于
肯定句，既可表示两人干了同样的事，也可表示一个人干了两件事，通常位于be动词，
助动词或
情态动词之后，
行为动词之前。如：
He has been to Beijing. I have also been there.他去过北京，我也去过。
He is good at English. He is also good at Japanese.他擅长英语，也擅长日语。
I also want some tea.我也要点茶。
注意：表示强调时，also也可放在
助动词或
情态动词等之前。比较：
I can also do it.我也能干。
I also can do it.(同上)
2.too也用于
肯定句，比also更通俗，和also, as well可以相互替换，可放在句中，也可放在句末。如：
Xiao Li went to Beijing and Xiao Zhao, too, went to Beijing.小李到北京去了，小赵也到北京去了。
He studies hard and I study hard, too.他学习用功，我（学习）也用功。
3.either用于
否定句，而且只能放在句末。如：
He didn’t know it.I didn’t know it either.他不知道那件事，我也不知道。
I can’t speak French and can’t write it, either.我不会讲法语，也不会写法语。
4.as well在口语中用得很多，用法和too完全一样，可以互换，通常位于句末。[见as well,as well as条]。如：
She not only sings,she plays the piano as well.她不但会唱歌，而且会弹钢琴。
I can do it as well.这事我也能做。
5.在含有责备、抱怨或规劝之类的句子中，若句子本身是以否定的形式表达肯定的意义时用“too”，而不用“either”。这类句子一般可用should,
had better, would rather等改成肯定的形式，只是语气稍有不同。如：
Can’t you see I’ve got teeth, too. 难道看不出我也有牙齿吗。（=You should see I’ve got teeth, too.）
6.在表示建议或邀请的句子中，若句子是否定的形式，肯定的意义，用“too”而不用“either”。这类句子在大都可以改成肯定的形式。如：
Won’t you come, too?你也来吗。（=Will you please come, too?或=Please come too. ）
Wouldn’t you have a cup of coffee too?您也来杯咖啡好吗。（=Please have a cup of coffee too.）
7.在
反意疑问句中，若主体句是肯定式，否定式的追加问句不影响整句的肯定意义，那么，主体句中可用“too”，而不可用“either”。如：
She went to see her last Sunday too, didn’t she?她上星期天也去看她了，（不）是吗。（=Did she go to see her last Sunday too?）
8.在具有否定意义的否定句中，
否定词前可用“too”而不用“either”。但这类句子更常用“not…ether”结构来表达。如：
He did not come, and she too did not come.他没来，她也没有来。（=He did not come, and she did not come either.）
I believed, too, that I had never listened so attentively.我觉得我从来没有这么用心地听讲过。
9.too虽在否定词后，但否定词仅仅是否定某个词或
片语，而不影响全句的肯定意义时，一般用“too”而不用“either”。如：
No worries and a comfortable place to sleep in are important, too.
无忧无虑，睡的地方舒适也非常重要
易混词
as well与as well as
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）.
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。
二. as well as用法
1. as well as常用来连接两个并列的成分,作“也,还”解。它强调的是前一项,后一项只是顺便提及。因此连接并列主语时,
谓语动词与前一项一致；而用not only ...but also...连接时,谓语动词与后一项一致。如：
Your wife as well as you is friendly to me.
不仅你而且你的妻子也对我很友好。
（=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.
2. as well as用来表示
同级比较,指“一样好”。如：
You look as well as you did ten years ago.
你的身体看起来还和十年前一样好。
He plays the guitar as well as you.
他的吉他弹得和你一样好。
