1、精选优质文档-倾情为你奉上定语从句一、定义：在复合句中，修饰名词或代词的从句叫定语从句 ， 被修饰的名词或代词叫先行词 ， 引导定语从句的引导词分为：关系代词 who, whom, whose, which, that等，和关系副词where, when, why等 ， 关系代词和关系副词在定语从句中担任句子成份，不可省略。1.由who引导的定语从句中 ， who用作主语 ， 如 ： This is the boy who often helps me.2.由whom引导的定语从句中，whom用作宾语，如：The man whom you are waiting for has gone ho
2、me.3.由whose引导的定语从句中 ， whose用作定语 ， 如 ： Do you know the girl whose skirt is white?4.由which引导的定语从句中，which用作主语或谓语动词的宾语或介词的宾语。如： The room in which there is a machine is a workshop（车间）.The river which is in front of my house is very clean.This is the pen which you want.注意 ：(1) whom, which用作介词宾语时 ， 介词可放在 w
3、hom、which之前 ， 也可放在从句原来的位置上；但在含有介词的动词固定词组中，介词只能放在原来的位置上。如： He is the very person whom we must take good care of.(2) 引导非限制性定语从句时，必须用关系代词which，不用that。如：I have lost my bag, which I like very much.(3)关系代词在句中作主语时，从句的谓语动词的人称和数必须和先行词保持一致。5.由that引导的定语从句中，that可以指人或物，在从句中作主语或谓语动词的宾语，但不能放在介词后面作介词宾语，即介词后只能用which
4、,不能用that.如：The book that I bought yesterday was written by Lu Xun.注意：在下面几种情况下必须用 that引导定语从句。(1) 先行词是不定代词something, nothing, anything，everything等, 如 ：All that we have to do is to practise English.(2) 先行词被序数词或形容词最高级所修饰，如：The first letter that I got from him will be kept in my case .(3) 先行词被all, any, e
5、very, each, few, little, no, some等修饰 ， 如：I have eaten up all the food that you gave me .(4) 先行词被the only, the very, the same, the last修饰时,如:H e is the only person that I want to talk with.(5) 先行词既有人又有物时，如:They talk about persons and things that they met .(6) 当句中已有who时 ,为避免重复 ， 如 ： Who is the man tha
6、t is giving us the class?6. 由when, where, why引导的定语从句，如: I dont know the reason why he was late. This is the place where we have lived for 5 years.Ill never forget the day when I met Mr Li for the first time.注意：先行词是表示地点时，如果从句的谓语动词是及物的，就用 that(which)，如果从句的谓语动词是不及物的，就用where引导。This is the house which /t
