初中英语定语从句用法详解及练习

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及定语从句之间起连接作用,同时又作定语从句的重要成分。

(定语从句中的关系词分为关系代词和关系副词两种)that which who whom whose when where why主语宾语定语表语指人who thatwhom that whosethat指物which thatwhich thatwhosethat注: 关系代词在句中充当主语、宾语，因此定语从句中不能再出现关系代词所替代的名词或代词。

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及非限制性定语从句。

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 stands near the train station is a supermarket.位于火车站附近的那座大楼是一家超市。

(作主语) The film (which) we saw last night was wonderful. 我们昨天晚上看的那部电影很好看。

(作宾语) 3.who, whom 用于指人,who 用作主语,whom 用作宾语。

在口语中,有时可用who 代替whom, 也可省略。

例如:The girl who often helps me with my English is from England.经常在英语方面帮助我的那个女孩是英国人。

(作主语) Who is the teacher (whom) Li Ming is talking to? 正在与李明谈话的老师是谁?(作宾语)注意:(1)当定语从句中含有介词,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。
