初中英语定语从句.doc

定语从句1. 基本知识精讲 在复合句中修饰名词或代词的从句叫做定语从句。被定语从句修饰的名词或代词叫先行词。用来引导定语从句的词叫关系词（分为关系代词和关系副词）。定语从句一般放在先行词之后。如：This is the engineer who will give us a talk on science. 先行词 关系词 定 语 从 句一、由关系代词引导的定语从句英语中的关系代词有who, whom, whose, which, that 和as。它们的用法如下：1. who，whom的用法 who 和 whom 指人，在从句中分别作主语、宾语。作动词宾语时常被省掉。在口语中可用who代替whom。 The young worker who invented this tool is her brother.This is the boy (whom) I helped.2. which的用法 which指物，在从句中作主语或宾语，作宾语是在非正式语体中可以省略。如：The factory which produces these cars is very large.This is the book (which) you want.3. whose 的用法 whose指人或物，在从句中作定语，不可省略。Whose有时可用of which替换。如：Do you live in the room whose window opens to the west?This is the student whose pronunciation is the best in our class.4. that的用法 that既可指人，也可指物，在从句中作主语或宾语。作宾语时，在非正式语体中常省略。如：There were once six blind men that/ who lived in a village in India.Wheat is a plant that/ which is grown in the north of China.The letter (that) I received was from my father.注意 只能用关系代词that的场合that既可以指人也可以指物，但在下列场合，要用that，而不用which或who。1. 先行词是不定代词all，anything，everything，nothing，much，little，few，any等时，只能用that。如：Thats all that I want to say.Everything that the parents do is for the good of their children.2. 先行词被all，any，no，the only，the very（恰好），little，few等词修饰时。如：Thank you for giving me the very book that Im looking for.He is the only person that was present at the meeting.I have read all the books (that) you gave me.3. 指物的先行词被形容词的最高级或被序数词修饰时。如：This is the best film that has been shown this year.I like the second football match that was held last week.4. 先行词中既有人又有物时。如：The hero has saved the horse and its rider that fell into the river.He talked about the school and the teachers that he had visited.5. 当先行词为the way，the time，the period等时，但that通常被省略。如：I dont like the way (that) you speak to her.This is the last time (that) I shall help you.6. 在which或who引导的特殊疑问句中，为避免重复用that引导取代which或who。用which不用that的情况 1.在引导非限定性定语从句时。 (错)The tree, that is four hundred years old, is very famous here. 2.先行词指物，且介词后 We depend on the land from which we get our food. We depend on the land that/which we get our food from. 3.先行词本身是that时 I dont that which he did.二、关系副词引导的定语从句英语中的关系副词有when，where，why等。在定语从句中充当状语，一般不可省略。1. when的用法 when指时间、修饰表示时间的先行词，在定语从句中作时间状语，相当于at/ in/ on which。如：How can I forget the day when (=on which) I joined the Youth League?I thought of the days when (=in which ) we studied together.He came at a time when the students needed him.2. where的用法 where指地点，修饰表示地点的先行词，在定语从句中作地点状语，相当于in/ on/ at which。如：This is the farm where (=on which) my grandfather once worked.That is the place where (=in which) we lived two years ago.3. why的用法 why指原因，修饰名词reason，在定语从句中作原因状语，相当于for which。如：I dont know the reason why (=for which) you get so angry with me.Do you know the reason why he was late for school?注意 表示时间、地点的名词后关系词的选用当先行词是表示时间、地点的名词时，有时用when/ where，有时用that/ which引导定语从句。这时要根据从句的谓语动词是及物的还是不及物的而定。如果是及物动词就用that/ which（作从句的主语或宾语）；如果是不及物动词，就用when/ where（作从句的状语。）试比较：This is the house where he lived last year.This is the house that/ which he visited last year.I thought of the happy days when I stayed in Beijing.I have never forgotten the days that/ which we spent together.三、练习练习一（一） 用关系代词或关系副词将下列每对句子连成一个复合句。1.
