分类

关系代词有主格宾格属格所有格)之分,并有指人与指物之分。that的用法最广,that 可指人也可指物。见表:

特殊代词

but,as,than作关系代词引导定语从句

hardly等)。but引导的肯定定语从句和否定的主句连用,达到强烈肯定的修饰效果。例如: There is no mother but loves her own children.(=There is no mother that/who does not love her own children.)没有不爱自己孩子的母亲。

as既可指人,也可指物,常在限制性定语从句中充当主、宾、表语。as引导的定语从句的先行词前面常有as /such /the same等修饰词。例如: ①He is as brave a man as ever lived.他是世界上最勇敢的人。 ②Don’t read such books as are not worth reading.不要读那些不值得读的书。 as作关系代词,还可用来引导非限制性定语从句,as引导的定语从句可放在句首、句中或句末。例如: ① Taiwan,as we all know,is an inseparable part of China. ②As we all know,Taiwan is an inseparable part of China. ③Taiwan is an inseparable part of China, as we all know.

than前通常有表比较的词。例如:Fewer friends than we had expected came to our evening party.来参加晚会的朋友比我们预料的还要少。

在使用上述三个特殊的关系代词时,还要注意区分下列两个词组:

基本用法

引导

定语从句

关系代词代表先行词,同时在从句中作一定的句子成分,如:

The girl whom I spoke to is my cousin.

跟我讲话的女孩是我表妹。(该句中whom既代表先行词the girl,在从句中作介词to的宾语。)

This is the pencil whose point is broken.

这就是那个折了尖的铅笔。(whose 指物,在限定性定语从句中作定语)

He came back for the book that he had forgotten.

他回来拿他忘记了的那本书。(that指物,在限定性定语从句中作宾语,可以省略)

先行词

which

如:

He said he saw me there, which was a lie.

他说在那儿看到了我,纯属谎言。

其他用法

关系代词that在从句中作宾语或表语时可省略, 如:

I've forgotten much of the Latin I once knew.

我已经忘了很多曾经学过的拉丁语

He's changed. He's not the man he was.

他变化很大,已不是过去的他了。

注释:关系代词在从句中作宾语时可省略,that在从句中作表语时也可省略。

非限定性定语从句中,不能用that作关系代词。

语法注意

1.常用that 不用which的情况:

(1)先行词为不定代词all,little,few,much,anything,everything, nothing, something等时。

I will do all (that) I can to help you.

(2)先行词被序数词、形容词最高级或the only, the very等所修饰或其本身就是序数词﹑形容词最高级时。

He was the only person that joined the army in his village that year.

(3)先行词既有人,又有物时

They talked about the people and the things (that)they remembered in the school.

(4)当主句是以who 或which开头的疑问句时,定语从句用that 引导,避免重复。

Who is the boy that was here just now?

2.若关系代词在定语从句中作介词宾语,介词可提前至关系代词前,此时关系代词只能用whom或which。

关系词通常是用来引导定语从句的,但as,than和but这三个词却与which,who,that,where,when和why等典型的关系词不同。三者本身具有常见的字面意义,前面有名词作先行词,但后面的定语从句却不像典型的定语从句。这些既像连接词又像关系词的词,我们就姑且称它们为准关系词。下面对其逐个作一分析:
