I.定义：定语是修饰名词或代词的成分,定语可由单词、短语来充当。当用一个句子来充当名词或代词的修饰语时，这种起定语作用的句子就被称为定语从句。
Theyhaveacleverson.
Doyouknowthemanoverthere?
Iknowthemanwhowrotethebook.
II.要点：
1.定语从句的前面都有先行词(被修饰语)
Thisistheboywhomwearelookingfor
2.定语从句应紧跟在先行词之后
3.先行词与定语从句之间要有关系词(有时可省略)
4.关系词在定语从句中充当某一成分
Thegirlwhoisstandingunderthetreeismysister.
Themanwhomyouwanttoseehascome.
III.关系词基本用法
|
|
主格 |
宾格 |
所有格 |
|
人 |
who |
whom |
whose |
|
物 |
which |
which |
of which |
但that一般可用来代替who,whom,which,作宾格时可省略
Doyouremembertheteacherthat/whotaughtusEnglish?
Abookstoreisastorethat/whichsellsbooks.
Theman(that/whom/who)youknowisafamousprofessor.
A)that不能用来替代who,whom,which的两种情况
1)“介词+whom/which”的结构中，不能用that
Sheisagoodstudentfromwhomweshouldlearn.
2)在非限制性定语从句中，逗号后面不能用that
Shesanganewsong,whichwelikeverymuch.
注意：非限制性定语从句的关系代词不能省略
B)用that不用which的一些特殊情况
1)先行词为all,much,little,something,anything,everything,nothing等
Isthereanything(that)Icandoforyou?
2)先行词前有形容词最高级修饰
ThisisthemostexcitingreportthatIhaveeverread.
3)先行词前有first,last,next,only,very,all,any等词修饰
Thefirststep(that)wearetotakeisverydifficult.
4)先行词同时含有“人”和“非人”时，用that不用which，也不用who/whom
Hetalkedaboutthepeopleandthebooksthatinterestedhim.
C)关系副词when,where,why
用关系副词when时，它的先行词是表示时间的名词，用where时先行词是表示地点的名词，而用why时它的先行词只可能是reason，使用时应注意以下几点：
1)关系代词的选择主要是看先行词在从句中所作的成分
ThisisthecitywhereIwasborn.
Thisisthecity(which/that)hehasvisited
Idon’tknowthereasonwhysheislate.
Thatisthereason(which/that)everybodyknows
Doyoustillrememberthedaywhenhearrived?
Doyoustillremembertheday(that/which)wespenttogether?
2)关系副词when,where,why可由“介词+which”的结构来替代
Isthisthereasonforwhichtheycame?
HeleftthedayonwhichIcame.
注意：how不能用来引导定语从句
Thisisthewayhowhedidit.
D)As作关系代词的用法
与thesame,such连用
ThisisthesamebookasIreadlastweek.
SuchbooksasIhavereadareclassicalworks.
