定语从句when和where的区分

一、考查关系词的指代及其在从句中所作的语法成分
定语从句要由关系词来引导,关系词分为关系代词和
关系副词。

关系代词有:who, whose, whom, that, which 等;关系副词有:when,where,why等。

除that只引导限定性定语从句外,其余的关系词既可以引导限定性定语从句,也可以引导非限定性定语从句。

要点提示:要正确使用关系词,就须将两个方面结合起来考虑:一方面是看看关系词所指代的先行词的类属;另一方面是准确分析关系词在定语从句中所作的句子成分。

若指人,作主语用who,作宾语用whom(可以省略),作定语用whose(还可指物);若指物且作主语或宾语,则用which(在非限定性定语从句中,也可指代一个情形,即主句全部内容。

无论作主语还是作宾语,均不可省略)或that(还能指人,作宾语时,可以省略);作状语指时间用when,指地点用where,指原因用why等。

考题:
1.His parents wouldn't let him marry anyone
_______ family was poor. (MET'88)
A.of whom
B.whom
C.of whose
D.whose
2.Dorothy was always speaking highly of her role in the play, _______ of course, made the others unhappy. (NMET2000)
A.who
B.which
C.this
D.what
3.After living in Paris for fifty years he returned to the small town _______ he grew up as a child. (NMET'96)
A.which
B.where
C.that
D.when
4.Carol said the work would be done by October, _______ personally I doubt very much.(NMET'99)
A.it
B.that
C.when
D.which
5.I also enjoyed the evenings when we spent together. (NMET'95短文改错)
答案及简析:
1.答案为D。

此处关系词指代的是anyone,而且作从句中的定语。

2.答案为B。

该题旨在考查非限定性定语从句的引导词,只能在A,B之间选择,可是这里并未指人,而是指主句所谈情况,为此,只能选B。

3.答案为B。

关系词指代地点the small town,同时在定语从句中充当状语。

4.答案为D。

不可认为指代时间by October而误选C。

其实,稍加分析就可清楚关系词指代的是主句全部内容且
作doubt的宾语而非状语。

5.此题先行词是表时间的名词evenings,但在从句中用作spent的宾语而不是状语,故须将when改为
that/which或去掉when。

二、考查关系词的搭配方式
关系词的搭配方式主要是指as及作提前介词宾语的which和whom的搭配方式。

(一)as的搭配方式
要点提示:1. 在限定性定语从句中,常见的搭配方式有:the same...as,as...as,not so / as...as, such...as 等。

2.在非限定性定语从句中,常见的搭配方式有:as we all know(=as is known to us all),as is
said(reported,mentioned,etc.)above,as it is等,可置于句首、句中或句末。

考题:
_______ is known to everybody,the moon travels round the earth once every month.(NMET2001)
A. It
B. As
C. That
D. What
答案与简析:答案为B.显而易见,为一固定搭配方
式.As引导的是非限定性定语从句。

(二)which和whom的搭配方式
要点提示:1.多用于限定性定语从句中,作提前介词的宾语,即介词+which/whom.介词的使用要依据定语从句中
动词短语的构成方式而定。

2.在作从句主语时,往往套用:名词(代词、数词
等)+of+which/whom.多见于非限定性定语从句中。

考题:
1.In the dark street,there wasn't a single person _______ she could turn for help. (NMET'92)
A.to whom
B.who
C.from whom
D.that
2.He paid the boy $10 for washing ten windows,most of _______ hadn't been cleaned for at least a year. (MET'90)
A.these
B.those
C.that
D.which
3.Recently I bought an ancient Chinese vase, ______ was very reasonable. (2000上海)
A.which price
B.the price of which
C.its price
D.the price of whose
答案与简析:
1.答案为A。

turn to sb. for help 是一固定搭配方式。

2.答案为D。

which指代ten windows且作of的宾语,that不能用在非限定性定语从句中,也不能与介词一起提前作宾语。

3.答案为B。

which指代the ancient Chinese vase,与the price构成所属关系。

三、考查使用that的情况及关系词的省略现象
(一)只能使用that的情况
要点提示:
1.由不定代词anything,nothing,everything,all, one, little,few,much等充当先行词时;
2. 当先行词前有序数词或形容词最高级修饰时;
3.当先行词被no,the same,the very, the only等修饰时;
4. 当先行词既指人又指物时;
5. 主句是以who开头的疑问句时.
考题:
All _______ is needed is a supply of oil. (MET'89)
A.the thing
B.that
C.what
D.which
答案与简析:答案为B,因为先行词是由不定代词all
充当的。

(二)关系词的省略现象
要点提示:除作宾语的关系代词whom,which,that可以省略外,先行词为way,time等时,可将that省略,其中way 还可以由in which来引导。

考题:
I don't like______you speak to her.(1993上海)
A.the way
B.the way in that
C.the way which
D.the way of which
答案与简析:答案为A.根据句意:我并不喜欢你对她讲话的方式,理应选the way,其后省去了关系代词that。
