as well和as well as的区别

文/叶丹

as well意为“也”,一般放在句末,as well as意为“(除……之外)也,还有”,用来连接两个并列成分,强调as well as前面的部分,当它连接两个并列主语时,可译为“和”,谓语动词要和第一个主语的人称和数保持一致,as well as还可意为“和……一样好”。

as well和as well as的区别

所有的主从复合句,主从句的时态都得一致。 一致并不意味着时态完全一样,只要从时间关系上讲得通即可。

用as soon as 引导时间从句时要注意"主将从现”即从句用一般现在时表将来。

如:I'll tell him about the news as soon as I see him.

as用作副词:

第一种是用在“as+(形容词或副词)+as”中,其中第一个as为副词(例句见上, as分别修饰形容词tall和副词long)

第二种表示以特定形式或关系考虑——通常用在介词或分词前

The ‘h’ in honest is silent, as in ‘hour’. honest中的h与hour中的h一样都不发音。

my opinion as distinguished from his:我的意见与他的不同

As always, he said little. 他和平时一样,少言寡语。

第三种表示举例:various trees, as oak or pine(同such as)

as用作代词(关系代词)

(a) 关系代词as引导限定性定语从句:一般用于以下固定结构中:

1. 用于the same…as结构中,例如:

This the same book as I read last week.

2. 用于such…as结构中

I don’t like such books as he recommends.

3. 用于“so+ adj +a/an +n + as”结构中

I am not so strong a man as I was.

即:当先行词含same、 such、so等时,关系代词要用as。

(b) 关系代词as引导非限定性定语从句:先行词是一个句子或短语:

As is often the case, she is late. (放在句首,先行词是整个句子she is late)

He is very careful, as his work shows. (放在句末,先行词是整个句子he is very careful)
