定语从句分为限定性定语从句和非限定性定语从句两种。
1、who, whom, that
限定性定语从句中的关系代词
1. that即可代表事物也可代表人,which代表事物;它们在从句中作主语或宾语,that在从句中作宾语时常可省略关系词,which在从句中作宾语则不能省略。而且,如果which在从句中作“不及物动词+介词”的介词的宾语,注意介词不要丢掉,而且介词总是放在关系代词which的前边,但有的则放在它原来的位置
2. which作宾语时,根据先行词与定语从句之间的语义关系,先行词与which之间的介词不能丢
3. 代表物时多用which,但在带有下列词的句子中用that而不用which,这些词包括all, anything, much等,这时的that常被省略
4. who和whom引导的从句用来修饰人,分别作从句中的主语和宾语,whom作宾语时,要注意它可以作动词的宾语也可以作介词的宾语
5. where是关系副词,用来表示地点的定语从句
6. when引导定语从句表示时间
〔注〕值得一提的是,表示时间“time"一词的定语从句只用when引导,有时不用任何关系代词,当然也不用that引导
By the time you arrive in London, we will have stayed there for two weeks.
I still remember the first time I met her.
Each time he goes to besiness trip, he brings a lot of living necessities, such as towers, soap, toothbrush etc.
7. whose是关系代词,修饰名词作定语,相当于所修饰成分的前置所有格
8. 当从句的逻辑主语是some, any, no, somebody, anybody, nobody, something, anything, everything或nothing时,常用there is来引导
二、非限定性定语从句:非限定性定语从句的作用是对所修饰的成分作进一步说明,通常和主句间用逗号隔开,将从句拿掉后其他部分仍可成立
1. which引导的非限定性定语从句来说明前面整个句子的情况或主句的某一部分
2. 在引导限定性定语从句时,that有时相当于in which, at which, for which或at which
Attitudes towards daydreaming are changing in much the same way that(in which) attitudes towards night dreaming have changed. 人们对白日做梦的态度正在改变,这与人们对夜间做梦的看法的变化有非常相似之处。
I like the music for the very reason that(for which) he dislike it. 我出于某种原因喜欢这种音乐,而他恰恰与我相反。
We arrived the day that(on which) they left. 刚好我们到的那天他们走了。
3. 有时as也可用作关系代词
4. 在非限定性定语从句中,不能用that,而用who, whom代表人,用which代表事物
特殊情况 只能用that的情况
先行词为everything,all,little,much等不定代词时;
先行词被all,every,no,any,some,little,much修饰时;
先行词被the only,the very,the same,the last修饰时;
先行词被序数词或形容词最高级修饰时;
先行词是be的表语或there be 的主语时;
先行词有人又有物时;
当主句是以who或which开头的特殊疑问句时。
不能用that的情况
介词前置时;
非限定性定语从句中
这些词代替指人,whom在定语从句中指人,"who"和“that”既可作主语又可作宾语(作宾语可以省略),可以指人也可以指物(who不可指物)。在从句中所起作用如下:
(1)Is he the man who/that wants to see you? 他是那个想见你的男人吗?(who/that在从句中作主语)
(2)He is the man (whom/that) I saw yesterday. 他就是我昨天见到的那个人。(whom/that在从句中作宾语)
(3)The man whom you spoke to just now is our English teacher. 刚刚和你说话的那个男人是我们的英语老师。(whom在从句中作宾语)
注:who在定语从句中指人,作主语和宾语,作宾语时可省略;做及物动词或介词的宾语,可省略。 [1]
2,which,that 用来指物(有六种情况只可用that而不用which)
(用作主语、宾语,作宾语时可以省略),例如:
(1)The prosperity which/that had never appeared before took on in the countryside.农村出现了前所未有的繁荣。(which/that在从句中作主语)
(2)The package (which/that) you are carrying is about to come unwrapped.你拿那个包裹快要散开了。(which/that在从句中作宾语)
注:which在定语从句中指物,可作主语或及物动词或介词的宾语,作宾语时可省略;that在定语从句中既可指人又可指物,在定语从句中作主语、宾语和表语,作宾语时可省略,指人时,相当于who或whom,指物时,相当于which,作介词宾语时,介词不可提到that前,当介词提前时,需要用which或whom来代替。[1]
2、whose
(只用作定语)
“whose”表示谁(可以为人也可以为物)的(东西)
例:A child whose parents are dead is called an orphan.双亲都死了的孩子叫做孤儿。(“whose parents”表示那个孩子的双亲)
He lives in a room whose window faces south.他住的那个房子的窗户是朝南的。(“whose”表示那个房子的窗户)
