高中定语从句要点讲解

定语从句三部曲1. 找出先行词；2. 确定先行词在从句中的成分：主语，宾语， 状语；3. 选择正确的关系词。几个关系代词的基本用法 that that: 可指人或物；可作主语，宾语。 指人时，相当于who或 whom； 指物时，相当于whichA letter _ is written in pencil is difficult to read. Do you know the gentleman _spoke just now?What is the question _they are talking about?Here is the man _you want to see. 只能用that 不能用which的情况1.先行词为不定代词时：all, much, everything, anything, nothing, something, none, the one.2.先行词被only, any, few, little, no, just, very, one of等修饰时； 3.先行词是序数词时或被序数词修饰时；4.先行词是最高级或被最高级修饰时； 5.先行词既有人又有物时；6.先行词是数次时；(two, ten, a hundred)7.如果有两个从句，其中一个关系代词已用which ,另一个关系代词宜用that，以避免重复； 8.疑问词是who或which，关系代词宜用that，以避免重复； 9.主句是There be 结构，修饰其主句的定语从句宜用that 作关系代词；10.被修饰成分为表语时，或者关系代词本身是定语从句的表语时,该关系代词宜用that。 (主语+be+n. /adj.; 主语+系动词+adj.)即学即用1.

The factory _ his father works is far from here. 只能用which不能用that 的情况：1. 介词后面只能用which； Is this the room in which Mr. White lives? 2. 非限定性定语从句中。 More and more people are beginning to learn English, which is becoming very popular in our country. 3.当关系代词后面带有插入语时； Heres the English grammar which, as I have told you, will help improve your English. 4. 先行词是those+复数名词. A shop should keep a stock of those goods which sell best. who, whom, whosewho: 主格, 在从句中作主语，只可指人；whom: 宾格，在从句中作宾语，只可指人；whose: 属格，在从句中作定语，可指人也可指物。（whose = of which或of whom） I like the students who work hard.

He who knows nothing but pretends to know everything is indeed a good-for nothing. 2. 在非限定性定语从句中； His mother, who loves him very much, is strict with him. 3在there be开头的句子中。 Here is a boy who wants to see you.When When 指时间，在定语从句中作时间状语。其先行词是表时间的名词（如：time, day, week, year, month等） He came last night when I was out.We will put off the picnic until next week, when the weather would be better.when = 介词+which I still remember the day when I first came to this school. (when= on which) He came at a time when we needed him most. (when= at which) We will never forget the year 1949, when the Peoples Republic of China was founded. (when= in which)比 较 I still remember the day _my brother joined the army. I still remember the days _we spent together. 先行词是时间名词，但在定语从句中做宾语或主语时，先行词不能用when。Where Where 指地点，在定语从句中作地点状语。其先行词是表示地点的名词。（如：place, school, factory, room等） This is the place where I was born. I live in the room where /in which he used to live. where = 介词+which I recently went back to the town where I was born. (where = in which) I would like to live in a country where there is plenty of sunshine. (where = in which)比 较 The small mountain village _we spent our holiday last month is now very famous. This is the park _they visited last year. 先行词是地点名词，但在定语从句中做宾语或主语时，先行词不能用where。Why Why 指原因，在定语从句中作原因状语。先行词为reason 时，可用for which指代。 The reason why / for which / (that) he didnt attend the meeting was that he was ill.比 较 I dont believe the reason that/which he gave me. Have you asked him the reason that may explain his success? 当关系词在从句中作主语或宾语时，不能用why 引导。 先行词在从句中做状语时，关系词才可以用when， where和why。补 充当先行词为way时，定语从句常用that, in which,或how引导，that常可以省略。 This is the way that / in which I do such things.Please do the experiment in the way that/which I have shown you. (做宾语)as 的用法He was a foreigner, _ I knew from his accent. A. that B. as C. where D. why如为限制性的，多用于the same as ; the same as；such as ; as many/much as；so as等结构中。 I have the same book as you (have). Her attitude to him was quite the same as it had always been. 比较： I live in the same house that he used to live in. Im wearing the same shirt as you wore yesterday.如为非限制性的，多单独引导一个定语从句，这种定语从句可置于句首、句中或句尾，译为“正如”。（动词常为know, see, expect, point out, etc.） As we all know, smoking is harmful to ones health . Smoking, as we all know, is harmful to one health. 补 充 无论是关系代词，还是关系副词，都在定语从句中充当一定的成分，因此，先行词在定语从句中不复出现。 【误】 This is the book that I borrowed it yesterday.【误】The English Corner is the place where people often go there to practice their spoken English.关系词的省略在下列情况下，关系词在非正式文体中可以省略:1. 关系代词that, which, who, whom在定语从句中做宾语时，常可省略。 Are these keys (that which) you were looking for？ The man (who/that) I was sitting next to on the plane talked all the time.2以the way为先行词的限制性定语从句通常由in which或that引导，而且通常可以省略。 I dont like the way (that/ in which) she walks. The way (that /in which) he answered the questions was surprising. 3在the time when, the place where, the reason why结构中，when, where, why可省略。 I shall never forget the day (when) we first met.
