6定语从句.pptVIP

* 在复合句中，修饰某一名词或代词的从句 叫定语从句;相当于名词和形容词的作用。 被定语从句所修饰的名词或代词叫先行词。 连接先行词和从句的词叫做关系代词或 关系副词 Do you know the man who spoke at the meeting just now? That is the house where he lived ten years ago. 关系代词和关系副词的作用 1、引导作用 2、替代作用 3、在定语从句中担当某个成分的作用 1 .Those who want to go please sign your names here. （ 主语） 2. This is the house where he was born. （地点状语） 3. Bill, who I met yesterday, asked me a lot of questions. （宾语） 关系代词（who, whom, which, that, whose） 的指代关系 定语 √ √ whose 宾语 主语 √ √ that 宾语 主语 √ which 宾语 √ whom （宾语） 主语 √ who 在定语从句中的作用 指物 指人 在限制性定语从句中，当先行词指物时，关系 词可用which或that，二者常可以互换； 但在下列情况中，只能用that，不用which： 当先行词是不定代词all, a lot, few, much, none, anything, nothing等或被不定代词all, any, no, much, little, few, every所修饰时。 All that can be done has been done. 　 We heard clearly every word that he said. (2) 当先行词是序数词或被序数词所修饰时。 The first thing that should be done is to get the tickets. (3) 当先行词是形容词最高级或被形容词最高级所修饰时. This is the best film that I have ever seen. (4) 当先行词被 the very, the only, the next, the last等所修饰时。 This is the very book that I want to find. (5) 当先行词既指人又指物时 She described in her compositions the people and places that impressed her most. 下面情况不用that: This is the book about 　　　　we are talking now． Tom studies hard and is ready to help others, 　　　　his parents expect. What’s that is flying in the sky? which ①介词后面： which ②非限性定语从句中： ③当先行词本身是that时： which 在下列情况中，只能用which ，不用that ： as 和which在引导非限制性定语从句时，这两个关系代词都指主句所表达的整个意思，且在定语从句中都可以作主语和宾语。但不同之处主要有两点： ①as引导的定语从句可置于句首，而which不可。 ②as代表前面的整个主句并在从句中作主语时，常可翻译为“正如，正像”；而which常译为“这一点，这件事” ③ 在限制性定语从局中，如果先行词被as, so ,the same, such 修饰时，关系代词常用as which和as的区别: which和as的区别 1._______ is reported in the newspapers , talks between the two countries are making progress. 2. Helen was much kinder to her youngest son than to the others , ______ , of course , made the others envy him . 3._________ I explained on the phone, your request will be considered at the next meeting. As As which ★ as多用于一些习惯用语中：
