Unit7定语从句讲解 一、概念: 1. 定语:用来修饰名词或代词的词 a tall building the book on the desk anything important the girl in red 2. 如果定语是句子,便称为定语从句。 I know the girl. The girl is dancing. (两个简单句) I know the girl who is dancing. (定语从句) 被修饰的词是_。这个词就称为先行词。 其中连接两个句子的是_, 称为关系词。关系词在从句中指代先 行词,并在从句中充当一定的成分,观察上句,关系词在从句中充当_。 二、具体用法: 1. 由who, that和which引导的关系从句,其前面一定有一个表示人或物的名词或代词。这个被修饰的名词或代词叫做先行词。 当先行词指人时,由who或that引导; 当先行词指物时,由which或that引导。 I don’t know the boy who is playing football. The film which we saw last night was wonderful. Mary likes music that is quiet and gentle. 2. who, that和which在关系从句中既可以作主语,也可以作宾语。 作主语时关系代词不可以省略;作宾语时,可以省略。 The man who lives next to us is a policeman. (who作主语,不能省) He is the man that I visited last week. (that作宾语,可以省) 3. whose在从句中作定语,表示“某人的”,whom在从句中只能做宾语 4. 定语从句的实质:二句合一 (合并条件:人物先行在句一,又占句二一席地) Mary is a girl. 合并为一个句子 She has long hair. 思路:留(保留先行词)-舍(舍去与先行词互指的词)-替(用关系词代替舍去部分) Mary is a girl who/that has long hair. 请把下列句子二句合一 1. I saw the man. He closed the door 2. The girl is happy. She won the race 【总结】 关系代词 先行词 所担当成分 典型例句 who 人 主语、宾语 I like people _ talk little but do much. I like stories _ my grandma told me.
