1、(二)语法讲解定语从句的用法和精练一、定语从句的概念 在复合句中,修饰某一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,定语从句一般放在先行词的后面。 二、定语从句的关系词 引导定语从句的关系词有关系代词和关系副词,常见的关系代词包括that, which, who(宾格whom,所有格whose)等,关系副词包where, when, why等。关系代词和关系副词放在先行词和定语从句之间起连接作用,同时又作定语从句的重要成分。 三、定语从句的分类 根据定语从句与先行词的关系,定语从句可分为限制性定语从句和非限制性定语从句。限制性定语从句紧跟先行词,主句与从句不用逗号分开,从句不可省
2、去,非限制性定语从句主句与从句之间有逗号分开,起补充说明作用,如省去,意思仍完整。 四、关系代词的用法 1. that 既可以用于指人,也可以用于指物。在从句中作主语或宾语,作主语时不可省略,作宾语可省略。例如: Mary likes music that is quiet and gentle.玛丽喜欢轻柔的音乐。(that作主语) The coat (that) I put on the desk is blue.我放在桌子上的那件外套是蓝色的。(that作宾语) 2.which用于指物,在句中作主语或宾语,作主语不可省略,作宾语可省略。例如: The building which sta

4、teacher (whom) Li Ming is talking to? 正在与李明谈话的老师是谁?(作宾语) 4whose 通常指人,也可指物,在定语从句中做定语,后面要紧跟被修饰的名词。 There are some people whose faces you can nevr forget. 有些人,他们的脸你永远难以忘怀。(定语从句修饰先行词people) I saw some trees whose leaves were black because of the polluted air. 我看见一些树的树叶由于空气污染而发黑。(定语从句修饰行词trees) 注意:(1)当定语
5、从句中含有介词,介词放在句末时,who, that, which可省略,但介词在关系代词前时,只能用“介词+which/whom”结构。例如: This is the house in which we lived last year.这是我们去年居住的房子。 Please tell me from whom you borrowed the English novel.请告诉我你从谁那借的这本英文小说。 (2)含有介词的固定动词词组中,介词不可前置,只能放在原来的位置上。例如: This is the person whom you are looking for. 这就是你要找的那个人。
6、(3)that 作介词的宾语时,介词不能放它的前面,只能放在从句中动词的后面。例如: The city that she lives in is very far away.她居住的城市非常远。 (4)关系词只能用that的情况: a. 先行词被序数词或形容词最高级所修饰,或本身是序数词、基数词、形容词最高级时,只能用that,而不用which.例如: He was the first person that passed the exam. 他是第一个通过考试的人。 b.被修饰的先行词为all, any, much, many, everything, anything, none, the

9、e back, which made us happy. 汤姆回来了,这使我们很高兴。 五、关系副词的用法 引导定语从句的关系副词有when, where或 why等。分别作状语,意义上相当于介词+which结构,分别代替表示时间、地点或原因的先行词。Awhen 指时间,在定语从句中作时间状语。 I still remember the day when I first came to this school. 我仍然记得我第一次来到这所学校的那一天。(when= on which) He came at a time when we needed him most. 他是在我们最需要他的时候
