定語從句初中教學課件
在復合句中,修飾名詞或代詞的從句叫定語從句,被修飾的名詞或代詞叫先行詞,引導定語從句的有關系代詞 who, whom, whose, which, that等和關系副詞where, when, why等 ,關系代詞和關系副詞在定語從句中擔任句子成份。
1.由who引導的定語從句中 ,who用作主語,如 : This is the boy who often helps me.
2.由whom引導的定語從句中,whom用作賓語,如:The man whom you are waiting for has gone home.
3.由whose引導的定語從句中 ,whose用作定語,如 : Do you know the girl whose skirt is white?
4.由which引導的定語從句中,which用作主語或謂語動詞的賓語或介詞的賓語,如:
The room in which there is a machine is a work shop.
The river which is in front of my house is very clean.
This is the pen which you want.
注意 :
(1)whom, which用作介詞賓語時,介詞可放在 whom、which之前,也可放在從句原來的位置上;但在含有介詞的動詞固定詞組中,介詞只能放在原來的位置上。如: He is the very person whom we must take good care of.
(2)引導非限制性定語從句時,必須用關系代詞which,不用that,如:I have lost
my bag, which I like very much.
(3)關系代詞在句中作主語時,從句的謂語動詞的人稱和數必須和先行詞保持一致。
5.由that引導的定語從句中,that可以指人或物,在從句中作主語或謂語動詞的賓語,但不能放在介詞后面作介詞賓語,如:
The book that I bought yesterday was written by Lu Xun.
注意在下面幾種情況下必須用 that引導定語從句。
(1)先行詞是不定代詞all, few, little, much, something, nothing, anything等,如 :
All that we have to do is to practise English.
