GRAMMAR定语从句（一）定语从句是在复合句中起定语作用，修饰某一名词或代词的从句。
被定语从句修饰的词叫先行词。
引导定语从句的关系词有关系代词（that, which, who, whom, whose等）和关系副词(where, when, why等)。
关系词在先行词和定语从句之间起着三个作用：①连接主句和从句；②指代先行词；③在从句中作句子成分。
本单元我们先来学习关系代词引导的定语从句。
【语境展示】观察下面句子，并试着归纳关系代词引导的定语从句的用法。
1. The people who / that called yesterday want to buy the house.2. The man (whom / who / that ) I have to phone lives in Canada.3. She was not in the train which / that arrived just now.4. This is the book (which / that) you wanted.5. The girl whose work got the prize is the youngest in her class.6. It’s the house whose door is painted red.【自我归纳】①关系代词who指人，在定语从句中作主语或宾语（句1、句2）。
②关系代词whom指人，在定语从句中作宾语, 在口语和非正式文体中可用who或that替换（句2）。
③关系代词which指物，在定语从句中作主语或宾语（句3、句4）。
④关系代词that既可以指人也可以指________，在定语从句中作主语或宾语（句1—句4）。
⑤关系代词whose既可指人也可指物，在定语从句中作________（句5、句6）。
注意：关系代词在从句中作宾语时，在口语中可省略（句2、句4）。
定语从句（一）一、基本概念（一）定语从句在复合句中作定语，修饰名词或代词的从句叫定语从句。
（二）先行词先行词是指被定语从句所修饰的名词或代词。
一般情况下，定语从句紧跟先行词。
但也有因各种原因定语从句与先行词被分割的现象。
（三）关系代词和关系副词定语从句的引导词与先行词关系密切，紧跟先行词，并在定语从句中充当一个成分。
定语从句的引导词分关系代词和关系副词两种：关系代词有who, whom, which, that和whose, 另外，as也可充当关系代词。
关系代词在定语从句中充当主语、宾语、表语和定语。
关系副词有when, where和why。
关系副词在定语从句中充当状语。
二、关系代词的用法（一）基本用法根据先行词及其在从定语句中所充当的成分不同，定语从句中要选用不同的关系代词。
如下表：e.g. (1) Do you know the professor who/that will give us a speech next week? (作主语)(2) I read a report about his new novel that/which will soon be published. (作主语)(3) The plan that/which they argued about was settled at last. (作宾语)(4) This is the new secretary (who/whom/that)I would like to introduce to you. (作宾语)(5) The soldier whose legs were badly wounded was operated on without delay. (作定语)注意：关系代词在定语从句中充当宾语时能够省略，充当主语时则不能。
（见上例(3)(4)）（二）关系代词that代替which的一些情况which, that 在代替物时，一般能够通用。
但在有些情况下，只能用关系代词that。
1. 先行词是形容词的最高级或它的前面有形容词的最高级来修饰时。
e.g. (1) This is the best that has been used against pollution.(2) English is the most difficult subject that you will learn during these years.2. 先行词是序数词，或它前面有一个序数词时。
e.g. (1) This is the last place (that) I want to visit.(2) It is the first American movie of this kind that I’ve ever seen.3. 先行词是all, much, little, something, everything, anything, nothing, none等代词时。
e.g. (1) You should hand in all that you have.(2) We haven’t got much that we can offer you.4. 先行词前面有the only, the very, any, few, little, no, all, much, every等修饰时。
e.g. (1) The only thing that we can do is to give you some money.(2) The little money (that) he had was stolen.（三）宜用who, 而不用that的一些情况1. 先行词是one, ones, anyone时。
e.g. (1) One who has nothing to fear for oneself dares to tell the truth.(2) Don’t tell anyone about the news who oughtn’t to know it.2. 先行词是those时。
e.g. Those who were not fit for their work could not see the beautiful clothes made of the magiccloth.（四）其它情况1. 先行词既有人又有物时。
e.g. (1) Do you know the things and persons that they are talking about?(2) The bike and its rider that had run over an old man were taken to the police station.2. 主句已有疑问词who 或which时。
e.g. (1) Which is the bike that you lost?(2) Who is the woman that was praised at the meeting?（五）与whose相关的问题1. whose是代词的所有格，它既能够代人也能够代物。
e.g. (1) I saw a woman whose bag was stolen.(2) Please show me the book whose cover is red.2. 当whose表示物与物的所有格关系时，亦可用of which的形式。
e.g. The building whose roof you can see from here is a new restaurant.→The building, the roof of which you can see from here, is a new restaurant. 或→The building, of which the roof you can see from here is a new restaurant.三、介词前提的问题关系代词在定语从句中充当介词宾语时，介词能够前提至关系代词前。
例如：Have you seen the pen (which) I wrote the note with just now? (which作介词with的宾语)→Have you seen the pen with which I wrote the note just now?注意：1. 介词提前后，当先行词是人或物时，关系代词分别只能用whom和which，而不再用that或who。
2. 介词提前后，关系代词不再能省略。
3. 有些含有介词的短语动词中的介词不能前提，如：look for, look after, take care of等。
e.g. (1) 错误：Who is the old man to that you were talking to?准确：Who is the old man to whom you were talking? 或Who is the old man (that/whom) you were talking to?(2) 错误：These are the sheep of which the boy took care.准确：These are the sheep (which/that) the boy took care of.四、关系代词在从句中作主语时，从句中的主谓一致关系代词在定语从句中作主语时，从句的谓语动词在人称和数上应与先行词一致。
e.g. (1) Who is the guy that is reading over there?(2) The number of people that are going to the exhibition is expected to be over 25,000.(3) All that needs to be done has been done.(4) He is one of the students who use computer a lot for study.(5) Timmy is the only one of the pupils that has failed the exam.例(3)中的all意为“一切”，作单数。
例(5)中没通过考试的学生事实上只有一人，所以谓语动词也用单数。
语法知识拓展一、选择适当的关系代词that, which, who, whom或whose，把下列句子补充完整。
1. Rice is a plant ________ is grown in the south.2. Those ________ want to go please sign their names here.3. All ________ glitters is not gold.4. This is the only way leads to your success.5. Both the girl and her dog were crossing the street were hit by a coming car.6. This is the biggest building ________we have ever built in our school.7.
