1、高三定语从句复习 1. This is the boy whom I am looking for.2. The woman who was speaking to me just now is my sister.一、概念：定语从句（Attributive Clauses）在句中做定语，修饰一个名词、代词或整个主句。引导词 （代替先行词）：关系词（关系代词或关系副词）关系代词有：who, whom, whose, that, which等。关系副词有： when, where, why等。二、 关系词在从句中的作用。 先行词在从句中的作用先行词是物先行词是人人、物主语宾语（可省）主语宾语（可
2、省）定语关系代词whichvvthatvvvvwhovvwhomvWhose v关系副词在从句中作状语：when指时间 why指原因 =介词+whichwhere指地点三、用 who, whom, whose, that, which填空。1.She is looking after the boy_parents have gone to London.2.Is this the photo _you took last summer?3.

3、5 years.5.I still remember the days_ I stayed in Beijing.6.This is the reason_ he was absent from the class.7.The friend_ came to supper last night was from Beijing.四、介词+关系代词(which/whom/) whom, which, 作介词宾语时，介词可以放在它们的前面，也可以放在从句原来的位置上，但是含有介词的动词固定词组中，介词应该放在原来的位置上。 1. This is the house _we lived in las
4、t year. This is the house _ _ we lived last year.2.The man _she was traveling with is her boyfriend. The man_ _she was traveling is her boyfriend.3.This is the person _you are looking for. 4.

5、on _ _ I spoke just now is my brother.7.He live in the house the window _ _ faces the south.8.

6、ether.3. I went to the place _ I worked ten years ago.4. I went to the place _ I visited ten years ago.5. This is the reason _ he was late.6. This is the reason _ he gave.六、关系代词that 和which的区别 1.宜用that引导的定语从句(1) 如果先行词是all, much, anything, something, nothing, everything, little, none等不定代词，例如： All the
7、people that are present burst into tears. (2) 先行词有两个，既有人也有物，要用that。We were talking about the persons and things that we remembered in our school.(3) 如果先行词被形容词最高级、序数词或any, only, few, mush, no, some, very等词修饰，例如：This is the most impressive TV theater that has never been put on show before .这是以前从未上演过的最
8、有感染力的电视剧。That is the only way that leads to your success .那是通向你成功的唯一之路。We have to consider the first thing that starts our work .我们必须要考虑启动我们工作的第一件事。 4） 以who或which开头的特殊疑问句，为避免重复。Who is the girl that is crying?5） 如果有两个定语从句，一个用which, 另一个用thatThe country built a factory which produced things that have n
9、ever been seen before.2. 宜用which引导的定语从句当定语从句的介词提前时，要用which。The house in which they lived last year has been rebuilt.引导非限制性定语从句时，要用which。He bought a railway ticket for the woman, which helped her a lot.七、区分限制性和非限制性定语从句1. She has two brothers who /that are working in the city.她有两个在这个城市工作的弟弟。2. She has
10、 two brothers, who are working in the city.她有两个弟弟，他们在这个城市工作。八、as 和which引导的非限制性定语从句as 和which在引导非限制性定语从句时，这两个关系代词都指主句所表达的整个意思，且在定语从句中都可以作主语和宾语。不同之处主要有： as 引导非限制性定语从句，可放在主句之前，之中或者主句之后，；which引导的非限制性定语从句只能放在主句之后。另外，as有“正如，正像”的意思。1）As we know, smoking is harmful to ones health.2）The sun heats the earth, w
11、hich is very important to us. 3）It rained hard yesterday, _ prevented me from going to the park.A. thatB. whichC. asD. it九、当先行词受such, the same修饰时，常用asI have never heard such a story as he tells.He is not such a fool as he looks.This is the same book as I lost last week.She wore the same dress as her
12、 young sister wore. 练习：1._I explained on the phone, your request will be considered at the next meeting. A.WhenB.After C.AsD.Since2. Ive bought the same dress _ she is wearing. A. as B. that C. which D. than 3._is known to everybody ,the moon travels around the earth once every month. A. It B. As C.
13、 That D. What4. Keep away from such persons_ will do harm to you. A. who B. that C. as D. like5._is often the case, we have worked out the production plan.AWhichBWhenCWhen DAs6. Bamboo is hollow（空的）, _ made it very light.A. as B. which C. that D. so答案：1. c 2. A 3. B 4. c 5. D 6.B十、区分定语从句和同位语从句1.定语从句修饰先行词，它和先行词是修饰关系；同位语从句说明先行词的具体内容，是补充说明的关系。2.定语从句由关系代词或者关系副词引导，关系词在句中充当成分，作宾语时可以省略；同位语从句主要由that引导，在句中一般不做成分。(1) The plane that has just taken off is for London. (2) The fact that he has been dead is clear.
