?。玻P(guān)系代詞的用法
(1) 如果先行詞是all, much, anything, something, nothing, everything, little, none等不定代詞,關(guān)系代詞一般只用that,不用which。例如:
All the people that are present burst into tears.
(2) 如果先等詞被形容詞最高級(jí)以及first, last, any, only, few, mush, no, some, very等詞修飾,關(guān)系代詞常用that,不用which, who,或whom。例如:
(3) 非限制性定語從句中,不能用關(guān)系代詞that,作賓語用的關(guān)系代詞也不能省略。例如:
There are about seven million people taking part in the election, most of whom、are well educated.
(4) which還有一種特殊用法,它可以引導(dǎo)從句修飾前面的整個(gè)主句,代替主句所表示的整體概念或部分概念。在這種從句中,which可以作主語,也可以作賓語或表語,多數(shù)情況下意思是與and this 相似,并可以指人。例如:
He succeeded in the competition, which made his parents very happy.
(5) that可指人或物,在從句中作表語,(指人作主語時(shí)多用who)僅用于限制性定語從句中。
(6) which可作表語,既可指人,以可指物。指人時(shí),一般指從事某種職業(yè)或是有種特征.品性或才能的人。Which引導(dǎo)的定語從句可以限制性的,也可以是非限制性的。
(7) 如果作先作詞的集體名詞著眼于集體的整體,關(guān)系代詞用which;若是指集體中的各個(gè)成員,則用who。
(8) 先行詞有兩個(gè),一個(gè)指人,一個(gè)指物,關(guān)系代詞應(yīng)該用that。例如:
The boy and the dog that are in the picture are very lovely.
(9) 如果先行詞是anyone, anybody, everyone, everybody, someone, somebody,關(guān)系代詞應(yīng)該用 who 或whom,不用 which。例如:
Is there anyone here who will go with you?
3.“介詞+關(guān)系代詞“是一個(gè)普遍使用的結(jié)構(gòu)
(1) “介詞+關(guān)系代詞“可以引導(dǎo)限制性定語從句,也可以引導(dǎo)非限制性定語從句?!敖樵~+關(guān)系代詞“結(jié)構(gòu)中的介詞可以是 in, on, about, from, for, with, to at, of, without 等,關(guān)系代詞只可用whom或 which,不可用 that 。
(2) from where為“介詞+關(guān)系副詞“結(jié)構(gòu),但也可以引導(dǎo)定語從句。例如:
We stood at the top of the hill, from where we can see the town..
(3) 像listen to, look at, depend on, pay attention to, take care of等固定短語動(dòng)詞,在定語從句中一般不宜將介詞與動(dòng)詞分開。例如:
This is the boy whom she has taken care of.
