1、人教新课标版高一必修1重点提炼：Unit 4 Earthquakes语法突破The Attributive Clause (1)定语从句（Attributive Clauses）在句中做定语，修饰一个名词或代词，被修饰的名词,词组或代词即先行词。定语从句通常出现在先行词之后，由关系词（关系代词或关系副词）引出。关系代词有：who, whom, whose, that, which等。关系副词有：when, where, why等。关系代词引导的定语从句关系代词所代替的先行词是人或物的名词或代词，并在句中充当主语、宾语、定语等成分。关系代词在定语从句中作主语时，从句谓语动词的人称和数要和先行词保
2、持一致。1）who, whom, that这些词代替的先行词是人的名词或代词，在从句中所起作用如下：Is he the man who/that wants to see you?他就是你想见的人吗？（who/that在从句中作主语）He is the man whom/ that I saw yesterday.他就是我昨天见的那个人。（whom/that在从句中作宾语）2） Whose 用来指人或物，（只用作定语, 若指物，它还可以同of which互换）, 例如：They rushed over to help the man whose car had broken down. 那人车
3、坏了，大家都跑过去帮忙。Please pass me the book whose （of which） cover is green.请递给我那本绿皮的书。3）which, that它们所代替的先行词是事物的名词或代词，在从句中可作主语、宾语等，例如：A prosperity which / that had never been seen before appears in the countryside. 农村出现了前所未有的繁荣。（which / that在句中作宾语）The package （which / that） you are carrying is about to com
4、e unwrapped. 你拿的包快散了。（which / that在句中作宾语） 关系代词引导的定语从句一、定语从句的基本概念 在复合句中，修饰某一个名词或代词或修饰整个主句的从句叫定语从句。被定语从句所修饰的词叫先行词，The man who/that lives next to us is a policeman.住在我隔壁的那个人是一名警察。You must do everything that I do.你必须做我所做的一切事情。在上面两句中的 man 和everything 是定语从句所修饰的词，叫先行词。定语从句放在先行词后面。引导定语从句的关系词有关系代词：that , whi
5、ch ,who (宾格whom ,所有格whose )和关系副词where, when .关系词（关系代词或关系副词）放在先行词和定语从句之间，起联系作用，同时又作定语从句的一个成分。也就是说关系词有两个作用：1.引导定语从句。2.代替先行词在其引导的定语从句中充当一定的句子成分。定语从句中的谓语动词要和先行词在人称和数上一致。二、由关系代词引导的定语从句： 关系代词例句that在从句中作主语或宾语(作宾语时that 可省略)指物A plane is a machine that can fly. (作主语) The noodles （that） I cooked were delicious

(作主语)The songs （which） Liu Dehua sang were very popular. (作宾语)who, whom在从句中分别作主语和宾语（如果介词放在从句后面，则whom可以
7、省略）指人The foreigner who visited our class yesterday is from Canada. (作主语)The boy who break the window is called Roy. (作主语)The person to whom you just talked is Mr. Li. (作宾语)Mrs. White is the person to whom you should write. (作宾语)Whose 在从句中作定语指人或物的所有格I like the girl whose hair is long. (作定语)三、关系代词that
