中学英语定语从句知识点归纳.doc

1) The man who lives next to us is a policeman.2) You must do everything that I do.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的后面。* 引导定语从句的词有关系代词that, which, who(宾格whom, 所有格whose)和关系副词where, when、why* 关系词常有三个作用：1、引导定语从句 2、代替先行词 3、在定语从句中担当一个成分二、关系代词引导的定语从句* 1.who指人，在从句中做主语 The boys who are playing football are from Class One. * 2. whom指人，在定语从句中充当宾语，常可省略。The man (who/whom) you met just now is my friend.* 3. which指物，在定语从句中做主语或者宾语，做宾语时可省略(1) Football is a game which is liked by most boys. ( which 在句子中做主语)(2) This is the pen (which) he bought yesterday. ( which 在句子中做宾语)* 4. that指人时，相当于who或者whom；指物时，相当于which，在定语从句中做主语或者宾语，做宾语时可省略。(1) The people that/who come to visit the city are all here. (在句子中做主语)(2) Where is the man （that/whom ）I saw this morning? (在句子中做宾语)* 5. whose通常指人，也可指物，在定语从句中做定语(1) He has a friend whose father is a doctor. (2) I lived in a house whose roof has fallen in.whose指物时，常用以下结构来代替(3)The classroom whose door is broken will soon be repaired.=The classroom the door of which is broken will soon be repaired.1、只能使用that,不用which 的情况：* 1） 当先行词是：all , any , anything , everything , nothing或被它们修饰时。All that can be done must be done . 凡是能做的都必须做。* 2）当先行词被形容词的最高级或序数词修饰时。例如：That is one of the most interesting books that are sold in the bookshop. 那是这家书店出售的最有趣的书之一。The first thing that we should do is to get some food. 我们该做的第一件事是弄点吃的。* 3）当先行词有：the only , the very , the same , the last 等修饰时。例如：My necklace is not the only thing thats missing. 我的项链不仅是丢掉的东西。* 4）当主句以who或which开头时，定语从句中引导词用that ,不用which 或 who ，以避免重复。例如：Who is the girl that is wearing a red coat? 正穿一件红色外套的女孩子是谁？* 5）当先行词既有人又有物时，用that 。例如：The writer and his novel that you have just talked about are really well known .你刚才谈起的那位作家以及他的小说确实很著名。2、只用which不用that的情况：* 1) 关系代词前有介词时； e.g. This is the room in which Lu Xun lived.* 2)非限定性定语从句中；作宾语用的关系代词也不能省略。e.g. That necklace, which you gave me as a present, was lost yesterday.He has a daughter, who works in a hospital.* 3) 先行词本身是that时； e.g. The clock is that which tells the time非限定性定语从句的作用是对所修饰的成分作进一步说明，通常是引导词和先行词之间用逗号隔开，将从句拿掉后其他部分仍可成立 。Charles Smith, who was my former teacher, retired last year. 查理史密斯去年退休了，他曾经是我的老师。（非限)There is somebody here who wants to speak to you这里有人要和你说话(限制性)* 4) which还有一种特殊用法，它可以引导从句修饰前面的整个主句，代替主句所表示的整体概念或部分概念。在这种从句中，which可以作主语，也可以作宾语或表语，多数情况下意思是与and this 相似，并可以指人。He did very well in the competition, which made his parents very happy.* 关系代词 whom， which 在定语从句中作介词宾语时，可以和介词一起放于先行词与定语从句之间，有时为了关系紧凑也可以将 whom 与 which 与先行词紧挨着书写，而将介词置于定语从句的后面，That was the room in which we had lived for ten years.= That was the room which we had lived in for ten years.* 像listen to, look at, take care of等固定短语动词，在定语从句中一般不宜将介词与动词分开。例如：This is the boy whom she has taken care of.三、关系副词引导的定语从句* 1、when：当主句中的先行词(即主句中被后面定语从句修饰的词)是表示时间意义的名词时，它只能作定语从句的时间状语，放在定语从句句首。如果定语从句的引导词是作该定语从句的主语或宾语，则要改用关系代词that或which来引导。例如：Ill never forget the day when I was born. (=Ill never forget my birthday.) 我永远不会忘记我出生的日子。The day (that) I always remember in all my life is my birthday. 我一生中最难忘的日子是我的生日。(that作定语从句that I always remember in all my life的宾语，that可以省略)* 2、where：当主句中的先行词是表示地点意义的名词时，它只能作其所在的定语从句的地点状语，放在定语从句的句首。如果定语从句的引导词作该定语从句的主语或宾语时，也要改用关系代词that或which来引导。例如：The factory where his father works is in the east of the cityThat is the factory (that) they visited last month. 那就是他们上个月参观过的工厂。(引导词that作定语从句(that) they visited last month的宾语，that可以省略)如：Dont forget the time (that) Ive told you. 不要忘记我告诉你的时间。(that用作told的宾语)Ill never forget the days when I worked with you. 我永远不会忘记我与你共事的日子。(when用作状语)He works in a factory that /which makes radio parts. 他在一家制造无线电零件的工厂工作。(that/ which 在从句中用作主语，且不能省略)He works in the factory where his father worked. 他在他父亲工作过的那家工厂工作。(where作状语)* 在定语从句的使用中，one
