1、定状宾从句讲解初中定语从句讲解及练习一、定义：在复合句中，修饰某一名词或代词的从句叫做定语从句。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(1)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。(1) Mr. Liu is the person (w

2、hom) you talked about.注意：关系代词whom在口语和非正式语体中常用who代替，可省略。(2) 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

3、；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，

4、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.* 具体使用时还要注意下列问题：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。Is there anything that I can do for you ? 有什么可以为你做的吗？All that can

5、 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 .The first thing that we should do is to get some food .* 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 .*

6、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 ?* 5）当先行词既有人又有物时，用that 。The writer and his novel that you have just talked about are really well known .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

7、语用的关系代词也不能省略。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 ye

8、ar./ There is somebody here who wants to speak to you * 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 w

9、hom 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

10、)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 time when we worked on the farm. He arrived in Beijing on the day when I left.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。It happened in November whe

11、n the weather was wet and cold. 这事发生在天气又湿又冷的十一月。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 f

12、actory where his father works is in the east of the cityThis is the room where (in which) I lived last year. Lets look for a place where we can swim. That is the factory (that) they visited last month. * 注意：不要以为在时间名词后就一定用关系副词when，在地点名词后就一定用关系副词 where，在表示原因的the reason后就一定用关系副词why。到底选用关系副词还是关系代词，关键是看它

13、们在从句中是用作状语(用关系副词)还是用作主语或宾语(用关系代词)。如：Dont forget the time (that) Ive told you. (that用作told的宾语)Ill never forget the days when I worked with you. (when用作状语)He works in a factory that /which makes radio parts. (that/ which 在从句中用作主语，且不能省略)He works in the factory where his father worked. where作状语)Thats th

14、e reason (that /which ) he explained to us. (that或which在从句中用作explained的宾语) Thats the reason why she left home. 那就是她离家出走的原因。(why在从句中作状语)* 英语中的关系副词主要是 when, where, why三个，不要想当然地将how用作关系副词修饰the way。如不说 This is the way how he spoke，可改为 This is how he spoke(how引导的是表语从句)，当然也可说成 This is the way (that/ in wh

15、ich) he spoke.(其中的that/ in which可省略)* 另外，when和where可引导限制性和非限制性定语从句，而why则只用于引导限制性定语从句，不用于引导非限制性定语从句。Sunday is a holiday , when people do not go to work.He took us into the classroom , where there were only a few students.* 在定语从句的使用中，one of后面的名词是复数，这个复数名词制约后面的定语从句的谓语动词，用复数；而在one of 前面有the或 the only时，后

16、面引导的定语从句中的谓语动词则用单数形式。He is the only one of the students who is elected? Jasper is one of those people who know about the accident .状语从句状语从句主要用来修饰主句或主句的谓语。一般可分为九大类，分别表示时间、地点、原因、目的、结果、条件、让步、比较和方式。尽管种类较多，但由于状语从句与汉语结构和用法相似，所以理解和掌握它并不难。状语从句的关键是要掌握引导不同状语从句的常用连接词和特殊的连接词即考点。现分别列举如下:1 时间状语从句常用引导词：when, as, w

27、, the museum will be open to the public next year . Hell go to the seaside for his holiday if (it is ) possible.另外，比较状语从句经常省略。例如：Im taller than he (is tall ). The higher the temperature (is), the greater the pressure (is ). 就状语从句而言,有时为了使语言言简意赅,常常将状语从句进行简化。状语从句的简化现象在口语中较为普遍,而且在高考中的复现率也较高。因此,有必要对其进行全面

28、、透彻的了解。状语从句的简化现象常存在于以下五种状语从句中:由if, unless等引导的条件状语从句;由although, though, even if / though等引导的让步状语从句;由when, while, as, before, after, until / till等引导的时间状语从句;由as, as if等引导的方式状语从句;由as, than等引导的比较状语从句。下面针对这五种情形作一归纳。(1)当状语从句的主语是it,且谓语动词是be时,it和be要完全简化掉。例如:If (it is) possible, he will help you out of the di

29、fficulty. You must attend the meeting unless (it is) inconvenient to you. (2)当状语从句的主语和主句的主语一致时,从句可以将主语和be动词简化掉。常用于以下几种情形:a.连词+形容词As (he was) young, he learned how to ride a bike.
