定语从句There are five boys who will play the game.主句定语从句先行词引导词或关系词关系代词关系副词找出下列定语从句中的先行词及关系代词Is he the man who wants to see you?

I’ve read every book that is borrowed from the library. (1) 先行词为all, none, everything, nothing, anything, few, little, much 等不定代词时。(2) 先行词被all, both, every, no, some, any, few, little, much等修饰时。I’ve read all the books that are about this matter. 先行词指物时一般关系代词that和which可以互换。但在下列情况下,关系代词一般用that不用which:Do the best that you can do.
This is the most interesting film that I have ever seen.(3) 先行词是序数词或被序数词修饰时。(4) 先行词是形容词最高级或被形容词最高级修饰时。He is the first that gave us some useful advice.
It is the first letter that I have written in French.(5) 先行词被the only, the very, the last, the
right修饰时This is the very book that belongs to him.(6) 先行词既有人又有物时They talked about the people and things that they remembered.(7) 关系代词在定语从句中作表语时He is no longer the boy that he used to be.(8) 当主句是以which/who的特殊疑问句时。
Which is the car that killed the boy?
Who is the boy that is standing by the door?(9) 如果一个句子有两个定语从句,其中一个关系代词已用which,另一个用that,以避免重复。Last year, he visited a factory which produced toys that sold well.先行词指人时其关系代词可用who, whom, 也可用that。但在下列情况下多用或需用who(1) 先行词是all, anyone, one, ones, those, people时多用who。The one who knows me well is Tom.(2) 当主句以there be(存在句)形式出现时。There is a young man who wants to see the manager.(4) 当先行词与定语从句之间有较长或较为复杂的成分分隔时。A new teacher will come tomorrow who will teach you German.(3) 如果复合句中有两个或更多的定语从句时,其中第一个从句已用了that,其他的定语从句一般用who引导,以避免重复。The student that I like is the one who is both diligent and honest.注意!1.关系代词在限制性定语从句中充当宾语时可以省略。2.whose后面一般要加名词。3.在关系代词引导的定语从句中,如果关系代词充当定语从句的主语,其后的谓语动词应与先行词的人称与数保持一致。先行词为one of… 短语时,一般情况下中心词为后面的名词。但是如果短语前出现了the或the only,中心词则为one。在“one of +复数名词”后跟定语从句时,先行词是one of 后的复数名词,定语从句中的谓语动词用复数;但如果是“the (only) one of +复数名词”时,先行词是the one,定语从句中的谓语动词用单数。He is one of the students who have received the prize in our class.He is the only one of the students who has received the prize in our class.1. 关系副词where引导的定语从句(1) 当先行词是表示地点的名词,如place, room, mountain, airport 等,同时又在从句中做地点状语时,定语从句需要用关系副词where引导。This is the park where they first met.They visited a factory where computers are made.(2) 通常,引导定语从句的where 大都可以转换成“介词+which”的形式。This is the park in which they first met.They visited a factory in which computers are made.(3) 当表示地点的先行词在从句中不是作状语,而是作主语、宾语或表语时,必须用关系代词that 或which 引导定语从句,而不是where。This is the park which/that they often visit.They visited a factory which/that makes computers.(1) 当先行词是表示时间的名词,如time, age, day, year, month, week等,同时又在从句中做时间状语时,定语从句需要用关系副词when引导。Do you still remember the day when you joined the league?That was the year when I first went abrod.He is looking forward to the days when he will stay with you.2. 关系副词when引导的定语从句(2) 与where一样,引导定语从句的when 也可以转换成“介词+which”的形式。Do you still remember the day on which you joined the league?That was the year in which I first went abrod.He is looking forward to the days during which he will stay with you.(3) 当表示时间的先行词在从句中不是作状语,而是作主语、宾语或表语时,必须用关系代词that 或which 引导定语从句,而不是when。I’ll remember the days which/that I spent with you.I’ll remember the days when we stayed together.He is looking forward to the days which/that will be very important in Chinese history.3. 关系副词why引导的定语从句(1) 当先行词是表示原因的名词reason,同时又在从句中做原因状语时,定语从句需要用关系副词why引导,此时的定语从句说明先行词的内容。Can you tell me the reason why you were late this morning?I don’t know the reason why he didn’t turn up at the party.(2) 关系副词why 可与 for which 替换。Is this the reason for which you failed in the exam.(3) 当表示原因的先行词在从句中不是作状语,而是作主语或宾语时,必须用关系代词that 或which 引导定语从句,而不是why。This is the reason (that/which) he set out.
这就是他陈述的理由。He gave the reason that/which might explain his absence.介词+关系代词引导的定语从句在“介词+关系代词”结构引导的定语从句中,关系代词指物就用which,指人用whom。
Do you know the boy to whom she was talking?
The little girl is reading a book, in which there are many pictures.1. 介词的确定方法(1) 根据先行词来确定介词。I’ll never forget the day on which I came here. Is this the bike on which you often ride?(2) 根据定语从句中的谓语动词或形容词来选介词。He’s the model from whom we should learn.Li Hong is the person from whom I borrowed some money.(3) 根据定语从句所表达的意义来确定介词。This book opened a window, through which we can see a wonderful world.Mother gave me the money with which I bought a book.Mr. Smith is the person for whom I am working now.The professor has two sons, both of whom are teaching in the same university.New York is famous for its skyscrapers, the highest of which has more than 100 storeys.He was educated at a local grammar school, after which he went on to Cambridge.2. 介词的位置介词一般放在关系代词 which 和 whom 之前,但也可以放在原来的位置上。This is the man from whom I learned the news.= This is the man (that/whom) I learned the news from.Is this the play (which/that) you were talking about just now?Mr. Brown is the teacher (who/that/whom) we show great respect for. 注意:当介词和动词组成一个固定短语时,介词通常不能移至 which 或 whom 之前。如:These are the three children whom I am looking after now.You are the very man whom I am looking for.I have many books which you can refer to.类似的短语还有:listen to; depend on; take care of; make use of; catch up with; hear of; look forward to…the waythatin which/I don’t like the way you speak to your mother.
I don’t like the way that you speak to your mother.
I don’t like the way in which you speak to your mother.关系副词引导的定语从句限制性定语从句和非限制性定语从句一、限制性定语从句所修饰的词代表一个、一些或一类特定的人或事物,这种定语从句已和她所修饰的词构成一个完整的意思,这事定语从句不能随便拿掉,否则剩下的主句就会失去意义或意思不完整。 Those who break law will be punished.
违法的人会受到惩罚。
(如果去掉定语从句,主句意思不明确) He is a man who I can turn to for help.
他是一个我能求得帮助的人。
(定语从句限制什么样的人,如果去掉定语从句,主句毫无意义。)二、非限制性定语从句对主句不起限定作用,只起补充说明作用,如果去掉定语从句,主句意思仍然完整。His father, who works in beijing, came back yesterday.
他爸爸在北京工作,昨天回来了。
(如果变成限制性定语从句,就意为“他在北京工作的爸爸昨天回来了。”言外之意他还有在其他地方工作的爸爸,这事逻辑上不能成立的。)三、限制性定语从句中关系代词作宾语时,且不在介词之后,可以省略。四、非限制性定语从句通常用逗号与主句隔开。当先行词指物时,非限制性定语从句不用that引导,而用which。非限制性定语从句中,关系代词作宾语不能省略。She has a brother who is a musician.
She has a brother, who is a musician.五、非限制性定语从句中关系代词which和as可指整个主句的意思或一部分意思。He invited me to dinner, which made me happy.
他邀请我吃饭,这使得我非常高兴。
(which作定语从句主语,指整个句子的意思)As everyone knows, China is country with a long history.
正如大家所知,中国是个历史悠久的国家。
As作know的宾语,指代整个主句的意思。as 引导定语从句时的用法1. as 引导限制性定语从句通常用于the same … as, such … as结构中I want the same shirt as my friend’s.
Such machines as are used in our workshop are made in China.
We should do more such exercises in the future ____ we did yesterday.
A. as B. which C. which D.than2. as引导非限制性定语从句既可放在主句之前,也可放在主句之后,用来修饰整个句子。通常用下列句型: as is known to all, as is said, as is reported, as is announced, as we all know, as I expect等。As I expected,he got the first place again in this mid-term examination.
正如我所预料的那样,他在这次期中考试中又获得了第一名。 Tom didn’t take away the same book as he lost yesterday.Tom brought the same book as/that he bought yesterday.六、as与which的区别(1)as引导的从句可以放在主句之前,而which引导的从句只能放在主句之后。(2)从意义上讲,which指前面主句的内容;而as指代的是作为一般人都知道的常识性的东西,因此常译成“就象……那样、正如所……的”。He made a long speech, as we expected.
正如我们所预料的,他做了长篇大论。He made a long speech, which was unexpected.
他做了冗长的发言,这一点大家没有预料到。(3)如果定语从句的内容对主句的内容起消极作用,则用which,而不用as。Tom drinks a lot every day, which his wife doesn’t like at all.
汤姆每天喝很多酒,他妻子一点也不喜欢他的这一做法。Thank you! Jim passed the driving test, ___ surprised

C. in which? D. from which Is there a shop around ____ we can buy some toilet articles?
A. that B. which
C. where D. what 这是一道陷阱题,很容易将你误导至 around which 这一答案。其实读懂句子后就不难发现,句中的 around 不是介词,而是副词,意思为“周围有没有一家商店可以买到卫生间用品?”如果当作介词就成了“有没有一家周围可以买到卫生间用品的商店?” There are two buildings, stands
nearly a hundred feet high. (04湖北)
A.the larger
B.the larger of them
C.the larger one that
D.the larger of which 要区别是并列句还是非限制性定语从句,关
键是看两个句子之间是否有连词,若有表示并列
关系的连词或分号破折号,那就是并列句;如果
两句之间没有这些连接符号,那就是非限制性定
语从句,此时就需考虑使用适当的关系代词或关
系副词了。前面的句子可以改为: There are two buildings; the larger of them
stands nearly a hundred feet high. It is reported that two schools,____ are being built in my hometown,will open next year. (07四川)
A. they both B. which both
C. both of them D. both of which 这道题很明显是一个非限制性定语从句,只能用 which 而不能用 them。 Last week, only two people came to look at the house, _______ wanted to buy it. (07安徽)
