1、 第 1 页 共 5 页 高考英语考前冲刺精选语法知识定语从句难点解析 一、如何正确使用连接主从句的引导词 一个定语从句的引导词是用关系代词还是关系副词,这是同学们首先遇到的一个难题,由于把握不准,所以出错较多。请看以下例子:1.A.That is the school _we studied three years ago.B.That is the school _ we built three years ago.2.A.Ive forgotten the exact day _ he gave me the film copy.B.Ive forgotten the exact day

2、 _ he fixed for me to have the operation.3.A.Beijing is a city _ there is the famous Summer Palace.B.Beijing is Chinas political and cultural center,_ has the most universities.通过解析我们可知:判断是用关系代词还是关系副词要看先行词在从句中的指代。如果是谓语与状语的关系,就用关系副词,如果是主谓或是动宾关系就用关系代词。二、弄清几个问题 1.区别清It+be引导的强调句与带有定语从句的复合句。请看下列两组句子:A.It

3、 was September 11,2001 _ the World Trade Center in New York was attacked.B.It was on September 11,2001_ the World Trade Center in New York was attacked.A.It was Wuhan _ Jill met the three-year-old girl and adopted her.B.It was in Wuhan _ Jill met the three-year-old girl and adopted her.去掉 It was 和连接

4、词(横线部分)。如果剩余部分仍是一个完整的句子,则是强调句;否则,那个空格中所用的引导词及其引导的部分就是定语从句。2.定冠词的有无 有时定冠词在句中有决定性的作用。有无定冠词影响着定语从句的结构。如:(1)This is one of the books that_(sell)well in the bookstore.(2)This is the one of the books that _(sell)well in the bookstore.再看:(1)Is this the boy _ you want to talk to?(2)Is this boy _ you want to

5、 talk to?3.注意标点符号的形式 有时我们会见到这样的句子:(1)Entering the room,I found a note on the table,_ read:Ive left for Harbin.(1)Entering the room,I found a note on the table._ read:Ive left for Harbin.一个标点符号决定一个句子的结构。在(1)中,横线前是一个逗号,说明逗号前后是一个句子的两个部分。根据句意可知逗号后是一个非限制性定语从句(2)中前后两句之间用了句号,说明前后是两个独立的句子,因此,空格处应填入能作主语 超越语法

6、:定语从句典型错误剖析 定语从句是中学英语中的一个重要语法项目,学生们在学习和使用中出现了这样或那样的错误。现将其中的一些典型错误句例总结如下,供大家引以为鉴。1.Is this the pen your father bought it for you?2.Have you been to the company where she works there?3.I shall never forget the days when I spent with you.第 2 页 共 5 页 4.Is this all what you want to say?5.He lived in a ho

7、use,in front of it he planted some beautiful flowers.6.Mother came back on December 21 when was my birthday.7.This is the ring for which she is looking.8.Is this history museum that some foreign friends visited last week?9.This is the monitor her English is the best in our class.10.As you know it,he

8、 has left for Australia.11.The meeting was put off,that was exactly what we wanted.12.I dont like the way which you treat your mother.13.He told the good news to those who was present at the meeting.14.The expert visited our school is from Shanghai.15.Whos the old man whom you just shook hands?拓展 引导

9、定语从句的词叫作关系代词或关系副词。关系代词有 who、whom、whose、that、which、as 等;关系副词有 when、where、why 等。它们具有三个功能:1.连接主句和从句;2.指代先行词;3.在从句中充当一种成分。如:This is the book that I want to buy.that连接主句This is the book和从句I want to buy,指代先行词book,并在从句中作buy的宾语。一、关系代词的用法 关系代词的选用:第一,取决于它指代的是人还是物,指代人时可用who、whom、that或as,指代物时用 that、which 或 as;第

10、二,取决于它在从句中充当的成分,关系代词在从句中可充当主语、宾语、定语等。如:1)The man who/that is standing at the door is my English teacher.站在门口的那个人是我的英语老师。(who/that 在从句中充当主语)2)Do you know the man whom/that we met in the street?你认识我们在街上碰到的那个人吗?(whom/that 在从句中充当宾语)指人的 who 和 whom 有格的区别:who 在从句中作主语(在非正式说法中也可作宾语),whom在从句中只能作宾语,不能作主语,也可以省略

11、。3)The problem that/which troubles us is how to finish the work in time.使我们烦恼的问题是怎样才能按时完成这项工作。(that/which 在从句中作主语)4)The book that/which I bought yesterday is worth reading.昨天我买的这本书值得一读。(that/which 在从句中作宾语,这时可以省略)关系代词 whose 一般指人,表示该人的,也可指物,表示该物的,在从句中作定语。如:Thats the painter whose works are so highly r

12、egarded.那位就是其作品受到很高评价的画家。The building whose roof we can see from here is a hotel.我们在这儿望得见屋顶的那座房子是一个旅馆。whose 在以物为先行词时,可用 of which 代替,尤其是口语中。上例相当于:The building the roof of which we can see from here is a hotel.二、介词+关系代词引导的定语从句 关系代词 whom,which 在定语从句中作介词的宾语时,可以跟介词一起放在主句和从句之间;当先行词指人时,介词后的关系代词用 whom,其余用 w

13、hich,这时的关系代词不能省略;有时为了使关系代词紧跟它所修饰的先行词,也可以把介词放在从句中有关动词的后面,这时的which 可用 that 替换。当介词放在从句有关动词的后面时,关系代词 which,that,whom 在口语中和非正式文体中经常省略。如:第 3 页 共 5 页 This is the room in which he used to live.=This is the room(which/that)he used to live in.这是他过去居住过的房间。Whos the man with whom you just shook hands?=Whos the m

14、an(that/whom)you just shook hands with?刚才你与他握手的那个人是谁?但含有介词的短语动词一般不拆开,介词仍放在动词的后面。如:This is the book(which/that)Im looking for.这就是我在找的那本书。在这类定语从句中,介词的选择一般根据动词的需要,如上述几例,或者根据先行词来决定。如:There is a mountain of which the top is always covered with snow.有一座山顶总是覆盖着雪的山。三、关于使用关系代词的几点说明:1.指物的关系代词 that 和 which 常可互

15、换,但下列情况下通常用关系代词 that:1)当先行词是:all,none,much,little,everything,everybody,everyone,nothing 等不定代词时。如:All(that)he said at the meeting encouraged us greatly.他在会上说的一切,使我们受到很大的鼓舞。2)当先行词前有形容词的最高级、序数词及 the last,the same,the only,the very 等修饰时。如:This is the best film(that)I have ever seen.这是我所看过影片中最好的一部。The fi

16、rst article(that)Lucy wrote in Chinese was good.露西用汉语写的第一篇文章很好。3)先行词中既含有人也含有物时。如:He talked about the teachers and schools(that)he had visited.他谈起他所访问过的老师和学校。2.关系代词作表语时一般不用 who,而用 that。如:He is not the man that he was.他不是从前的他了。(从句中 that 是 was 的表语)3.若含有疑问代词:who,which,what 等时,应避免使用关系代词 who,which,而应用 tha

17、t。如:Who that knows him will believe him.认识他的人会相信他。Which of the two cows(that)you keep produces more milk?你养的两头奶牛,哪头产奶多?拓展-when,where,why 引导定语从句学习四要素 when、where、why 引导的定语从句是定语从句重要内容,也是高考重要考点,学习这些定语从句时应注意下列几点:一、掌握 when、where、why 基本用法 when、where、why 是关系副词,其基本用法如下表。关系副词 属性 在句中作用 例 句 when 表时间 时间状语 I reme

18、mber the days when I stayed there.where 表地点 地点状语 This is the room where I lost my pen.why 表原因 原因状语 This is the reason why he was late.二、熟悉易误用 when,where,why 的场合 若先行词虽表时间、地点、原因,但在定语从句中不作时间、地点和原因状语而作主语或宾语,属于关系代词范畴,应用关系代词 that 或 which,而不能用关系副词 when,where,why 引导定语从句。例:I regret the days(that/which)I wast

19、ed in the woods.我后悔在森林里虚度的日子。(先行词在从句中作宾语)Ill never forget the year 1976 which/that was full of sadness.我不会忘记充满悲哀的 1976 年。第 4 页 共 5 页(先行词在从句中作主语)That is the factory that/which produces cars.那是生产小汽车的工厂。(先行词在从句中作主语)That is the factory(that/which)he visited yesterday.那是他昨天参观的工厂。(先行词在从句中作宾语)He gave the r

20、eason that/which was unreasonable.他给出一个没道理的理由。(先行词在从句中作主语)What is the reason(that/which)he raised?他提出的理由是什么?(先行词在从句中作宾语)三、了解关系副词与关系代词转换规律 关系代词 whom 或 which 在定语从句中作介词宾语时,介词可放在后面,也可提前构成介词+关系代词 whom(先行词指人)/which(先行词指物)引导定语从句(这种方法更为正式)。例:Mary is the girl whom I borrowed a book from.=Mary is the girl fro

21、m whom I borrowed a book.玛丽就是我向她借书的那个女孩。Is this the room that/which he once lived in?=Is this the room in which he once lived?这是他曾经住过的房子吗?常见的有以下几种情况:1.where=in/on which 例:This is the room where/in which he lives.这是他住的房间。I can see the playground where/on which they do sports.我能看见他们进行运动的操场。2.when=on/i

22、n/at which 例:I still remember the year when/in which I joined the Party.我仍然记得入党的那一年。I still remember the day when/on which I joined the Party.我仍然记得入党的那一天。I still remember the hour when/at which the rocket was launched.我仍然记得那个火箭发射的时刻。3.why=for which 例:This is the reason why/for which he was killed.这是

23、他被杀害的原因。但下列情况下介词不能提前:用 who 代替 whom,用 that 代替 which 时,介词不能提前。例:Hes the boy who I learned English from.这是我向他学英语的男孩。This should be the place that Tom sent the parcel to.这应是汤姆送包裹的地方。当 whom、which 省去时介词不能提前。例:Is he the boy you went there with?他是和你一起去那儿的男孩吗?This is the room he lived in.这是他住过的房间。当 whom,whic

24、h 作为含有介词的动词短语的宾语时,介词一般来说不能拆开提前。例:Youre the very man whom Im looking for.你正是我在找的那个人。This is the program which he listened to.这就是他听过的节目。再看下面几种结构:(一)介词+whose 引导的定语从句 whose 引导定语从句时,可出现创新句型:介词+whose 引导定语从句。解这种定语从句时需弄清从句的动词与先行词、whose 后边的名词及定语从句主语之间的关系,并发挥合理想象,不难发现其中正确的逻辑关系。例:She is the girl to whose fathe

25、r I talked yesterday.她就是昨天我和其父亲谈话的女孩。He is the boy for whose boss I work.他就是我为其老板打工的男孩。(二)复杂介词+whom/which 引导定语从句 I stay at the hotel at the back of which is a small garden.我住在后面有一座花园的旅馆。第 5 页 共 5 页(三)数词(不定量数词)/含所属关系名词+of whom/which 引导定语从句。例:She has many books,only one of which is interesting.她有许多书,只

26、有一本是有趣的。四、明确 when,where 引导定语从句需特别注意的情况 1.when 引导定语从句需特别注意的情况(1)当先行词为 time,time 前面有序数词或 last 加以修饰时,应用 that 而不用 when 引导定语从句。例:This is the first/last time that I shall give you a lesson.这是我第一次/最后一次给你们上课。This is the third time that he has been to Beijing.这是他第三次去北京。(2)当 time 前面没有序数词或 last 加以修饰时,既可用 when

27、又可用 that 引导定语从句。例:Can you tell me the exact time when/that the sports meeting will be held?你告诉我运动会举行的确切时间吗?2.where 引导定语从句需特别注意的情况 当 point,situation 等词作先行词引导定语从句时表抽象的地点,若在定语从句中作地点状语,应由 where 引导定语从句。Can you think out a situation where this word can be used?你能设想出这个单词被使用的场合吗?Her illness has developed to the point where nobody can cure her.她的病发展到没人能治的地步。
