初中英语定语从句讲解及练习公开课

1、定语从句(Attributive Clauses)修饰一个名词或代词的从句称为定语从句，一般紧跟在它所修饰的先行词后面。引导定 语从句的关联词成为关系词。关系词有关系代词和关系副词。关系代词有that, which, who, whom, whose 等； 关系副词有 where, when, why 等。关系词常有3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。 一、关系代词引导的定语从句l.who指人，在从句中做主语，whom指人，在定语从句中充当宾语，常可省略。The boys who are playing football are from Class On

2、e.Yesterday I helped an old man who lost his way.Mr. Liu is the person (whom) you talked about on the bus.Mr. Ling is just the boy whom I want to see.The man who/whom you met just now is my friend.which指物，在定语从句中做主语或者宾语，做宾语时可省略Football is a game which is liked by most boys.This is the pen (which) he

3、bought yesterday.that指人时，相当于who或者whom；指物时，相当于which。在宾语从句中做主语或者 宾语，做宾语时可省略。Where is the man that/whom I saw this morning?whose通常指人，也可指物，在定语从句中做定语He has a friend whose father is a doctor.I once lived in a house whose roof has fallen down.二.介词+关系代词引导的定语从句关系代词在定语从句中做介词宾语时，从句常由介词+关系代词引导The school (that/w

4、hich) he once studied in is very famous.The school in which he once studied is very famous.Tomorrow I will bring here a magazine (that/which) you asked for.Tomorrow I will bring here a magazine for which you asked.注意：1.含有介词的动词短语一般不拆开使用，如：look for, look after, take care of等This is the watch which/tha

5、t I am looking for. (T)This is the watch for which I am looking. (F)介词放在关系代词前，关系代词指人时用whom,不可用who或者that；指物时用 which,不能用that；关系代词是所有格时用whoseThe man with whom you talked is my friend. (T)The tool pith which he is working is called a hammer. (T)三.关系副词引导的定语从句when指时间，在定语从句中做时间状语I still remember the day wh

6、en I first came to the school.The time when we got together finally came.where指地点，在定语从句中做地点状语Shanghai is the city where I was bom.The house where I lived ten years ago has been pulled down.why指原因，在定语从句中做原因状语Please tell me the reason why you missed the plane.I dont know the reason why he looks unhapp

7、y today.注意：关系副词引导的从句可以由“介词+关系代词”引导的从句替换The reason why/ for which he refused the invitation is not clear,Great changes have taken place in the city in which/where I was born.关系副词when, where, why的含义相当于介词+ which”结构，因此常常和介词+ whichH 结构交替使用，例如：Beijing is the place where (in which) I was born.北京是我的出生地。Is t

8、his the reason why (for which) he refused our offer?这就是他拒绝我们帮助他的理由吗?注意限制性定语从句只能用that不用which的几种情况领先彳亍词是 anything, everything, nothing (something 除夕卜)，few, all, none, little, some等代词时,或者是由 every, any, all, some, no, little, few, much 等修饰时Have you taken down everything that Mr. Li has said?There seems

11、中作表语时(l)China is not the countiy (that) it was.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 wh

27、 car factory was built there last month.一般将来时：shall / will + be doneCars will be sent abroad by sea.过去将来时：should / would + be doneThe manager said the project would be completed by the end of the year.现在进行时：am / is / are + being + doneEnglish lessons are being broadcasted on the radio.过去进行时： was / w

28、ere + being + done The road was being mended.现在完成时：have / has + been + doneI have been told the sports meeting might be put off.过去完成时：had + been + doneWhen I got to the theatre, I found the tickets had already been sold out.含有情态动词的被动语态：情态动词+ be + doneYour compositions must be handed in after class.(

29、三)语态转换时所注意的问题.把主动语态变为被动语态时，其谓语动词的时态要与原句时态保持一致，其谓语动词的 数要与新主语保持一致。We have bought a new computer. A new computer.含有双宾语的主动句变被动句时，可分别将其中的一个宾语变为主语，另一个不动，一 般变间接宾语为主语时比拟多。My uncle gave me a present on my birthday.a present on my birthday.如果把直接宾语(指物)改为主语，那么在间接宾语(指人)前加适当的介词，如上句还可以说：A presenton my birthday.注意：

30、.一般在以下动词后，常在间接宾语前用介词to,如：bring, give, hand, lend, offer, pass, pay, promise, sell, show, take, teach, tell 等。The book was showed to the class. (2) My bike was lent to her.一般在以下动词后，间接宾语前用介词for,如：build, buy, cook, cut, choose, do, fetch, find, fix, get, keep, make, order, paint, play, sing 等。A new ski

31、rt was made for me.(2) The meat was cooked for us.由动词+介词或副词构成的短语动词，要把它们作为整体看，即把它们看成一个及物动 词，介词或副词不可拆开或漏掉。这类动词有：不及物动词+ 介词，如：agree to, ask for, laugh at, operated on, listen to, look after, think of, talk about 等。The patient is being operated on.The problem is solved. It neednt be talked about.不及物动词+ 副

32、词：如:bring about, carry out, find out, give up, hand in, make out, pass on, point out, put away, put off, think over, turn down, work out, turn out 等。His request was turned down.The sports meet will be put off because of the bad weather.带复合宾语（宾语+宾补）的动词改为被动语态时，一般把主动结构中的宾语改为主语，而 宾语补足语保存在谓语动词后面。如：We alw

33、ays keep the classroom clean.一The classroom is always kept clean.She told us to follow her instructions.一We were told to follow her instructions.注意：在 see, watch, hear, notice, listen to, find, look at, make, feel 等动词后作宾语补足 语的动词不定式都不带to,但改成被动语态后都带to.We often hear him play the guitar. 一He is often hea

34、rd to play the guitar.当主动句的主语是nobody, no one等含有否认意义的不定代词时，被动句中将其变为 anybody,作by的宾语，并将谓语动词变为否认的被动语态。如： Nobody can answer this question. The question can not be answered by anybody.当否认句中的宾语是anything, anybody, anyone等不定代词时，在被动句中应将其分别变 为nothing, nobody, no one作主语，并将谓语动词变为肯定的被动语态。如： They havent done anyth

35、ing to make the river clean.Nothing has been done to make the river clean.（四）以下情况主动句不能改为被动句：1 感官系动词一般用主动形式表示被动意义，如：feel, look, seem, taste, sound, remain2、不及物动词，一些不及物动词短语没有被动语态，如：appear, happen, rise,take place, break out, belong to,3、宾语是反身代词，相互代词，同源宾语，不定式，v-ing形式及抽象名词等，不能变为被 动句子的主语，如：I taught mysel

36、f English.We love each other.4、有些动词既是及物又是不及物，当它们和well, badly, easily等副词连用时，表示主语内 在品质或性能，是不及物动词，用主动表示被动，这时不用被动语态，常见的有：write, read, clean, sell, wash, cook 等。如：（2）The new product sells well.The books were sold out.（被动句）The meat was cooked for a long time.（被动旬（1 ）The cloth washes easily.比照：The books se

37、ll well.（主动句）The meat didn 7 cook well.（主动句）（五）在汉语中，有一类句子不出现主语，在英语中一般可用被动结构来表示，例如:据说Itis said that.据报导It is reported that .据推测It is supposed that.希望Itis hoped that .众所周知It is well known that.普遍认为It is generally considered that.有人建议It is suggested that.It is reported that it is going to rain tomorrow
