also,too 和 either
also表示"也"是比較正式的用詞,too 是普通用詞,口語(yǔ)中用的多,使用時(shí)
應(yīng)注意:
also 一般用于句子中,其位置在行為動(dòng)詞之前,動(dòng)詞to be之后.如有
助動(dòng)詞或情態(tài)動(dòng)詞,一般應(yīng)在助動(dòng)詞或情態(tài)動(dòng)詞后,為了強(qiáng)調(diào),也可
放在前面.例如：
*I also went.
我也去了.
*You are also wrong.
你也錯(cuò)了.
too常置于句末,前面可用逗號(hào),如置于句中,其前后均有逗號(hào).例如
*He is a singer ,too.
他也是歌唱家.
*He,too,is a singer.
注意:also,too只能用于肯定句.
either neither
either 表示“也”,只能用在否定句中,必須放在句末.例如：
*He didn''t go there.I didn''t either.
你不去那里,我也不去那里.
neither表示"兩者都不".
Eg.In neither case can I agree.
兩種情形我都不能同意.
Eg.Neither of them wants to stop for a rest．
他們倆人誰(shuí)也不愿意停下來(lái)休息.
as well as 作并列連詞相當(dāng)于not only…but also和no less…than,但not only…but also側(cè)重在后項(xiàng),as well as 和no less…than 側(cè)重在前項(xiàng).例如：
We must learn to look at problems all-sidedly,seeing the reverse as well as the obverse side or things.
A true man should be practical as well as far-sighted.
在否定句中,as well as 的位置不同,句意往往有很大差別.比較下面的句子：
He,as well as she,will not come.他將不來(lái),她也將不來(lái).
He will not come as well as she.她將來(lái),但他將不來(lái).（否定前者,肯定后者）
Henry,as well as his brother,doesn''t work hard.亨利同他弟弟一樣,工作不努力.
Henry doesn''t work hard as well as him brother.亨利工作不努力,但他弟弟努力.
as well as 連接的應(yīng)是平等成分,都作主語(yǔ)或都作賓語(yǔ)等.例如：
She was there as well as me.（誤）
She was there as well as I .（正）
