2、副词。定语从句的种类： 1. 限制性定语从句：通常与主句紧密相连，译为“的”如果去掉整个句子所表达的意思就不完整了。Eg: This is the book that I want to read. 2. 非限制性定语从句：在结构上通常与主句用逗号隔开，如果去掉的话不影响主句的意思。Eg: The book, whose cover is very beautiful, belongs to him.关系词的作用：1. 引导定语从句，连接主从句。 2. 指代先行词。 3. 在定语从句中充当成分。 关系代词：主、宾、表、定。 关系副词：状关系词先行词从句成分例 句备 注关系代 词who人主、宾D

Eg： Who is the man that is making a speech? （6）先行词在主句中作表语，关系词在从句中作表语时。Eg: Marry is no longer the girl that she used to be. 只能用which做关系词的情况：(1) 引导非限制性定语从句，指前面的某事物或前面的整个主句并在句中做主、宾语时。Eg: He had failed in th

11、as结构中，as为关系代词，替代先行词，引导的是定语从句；在suchthat结构中，that为连词，引导的是一个完整的结果状语从句。Eg: Thats the same tool as I used last week.（同类工具，不是同一把）Thats the same tool that I used last week. (同一把) 定语从句中的主谓一致：(1) 关系词在从句中作主语时，从句谓语动词的单复数由先行词决定。Eg: The man who lives downstairs speaks English fluently. The students who are in Gra

12、de 3 are going to climb the hill tomorrow. (2）当先行词为one of the +复数名词时，定从的谓动用复数动词； 当先行词为the (only)one of the +复数名词时，定从的谓动用单数动词。 Eg: He is the only one of the students that is never late .他是学生中唯一从不迟到的学生。 He isone of the students thatare never late .他是从不迟到的学生之一。 关系副词相关考点：(1)当先行词为situation, case, point,

13、job, condition等表示情况、方面的模糊化、抽象化的地方并且从句中缺少状语时，常用where引导定从。Eg:Can you think of a situation where we can use this word correctly?After graduation she reached a point in her career where she needed decide what to do.(2)the way 做定语从句的先行词时，如果定从中少状语，用that、in which或来引导定语从句。如果少宾语用that 、which 或。如少主语用that 、whic

23、sult of, at the back of, because of, by means of, for want of, in front of, in case of, on account of等。Eg：We got to a house at the back of which was a large garden.解题基本步骤：1.判断是否为定语从句；2.找出从句中所缺成分(主语、宾语、定语、表语、状语)从而判断是用关系代词还是关系副词；3.找出先行词(看是人、物或者是其他状语)注：缺主语：从句中谓语动词前没有主语。 缺宾语：1.从句中谓语动词为及物动词，后无宾语时；2.从句中介词

24、后无宾语；3.从句中谓语动词为后可跟双宾语的动词 缺表语：从句中系动词后无表语时； 缺定语：从句中的主语与先行词表所属关系时； 缺状语： 1.被动语态中；2.主系表结构的句子里；3.谓语动词为不及物动词的句子里。既缺先行词，又缺引导词的情况，如：1)Isthisfactory_wevisitedlastyear?2)Isthisthefactory_wevisitedlastyear?A.thatB.whichC.theoneD.what解析：此类题目我们应先将其变为陈述句。1)变后为：Thisfactoryis_wevisitedlastyear。再有其汉语意思“这个工厂是我们去年参观的那一

25、个”。可知1)中缺少先行词，答案中只有项theone这个代词可以充当。故1)答案 C。2)变为陈述句后为：Thisisthefactory_wevisitedlastyear。由此可知此句缺少引导词。切先行词在从句中作宾语，因此答案为A或B。选择引导定语从句的引导词是学习定语从句的难点。巧用以下口决，可化难为易。一看指人还是物，二看介词在何处；三看句中作何用，四看否属特殊。定语从句 一、考点聚焦 1、功能：相当于形容词，修饰名词或代词，在句中作定语2、位置：定语从句置于被修饰词之后Those who are willing to attend the party, sign here plea

26、se.3、先行词：被定语从句修饰的词称为先行词（1）先行词一般是名词和不定代词，如:some-, any-, every-和no与-boy, -thing的合成词；或all、none、any、some、that、those等代词。数词也可以作先行词，人称代词也同样可作先行词。（2）先行词与关系词是等量关系。必须注意两点：先行词在从句中作主语时，从句谓语动词的数由先行词而定。This is the place which is worth visiting.关系词在从句句子中充当了成分，其意思就是先行词的意义，所以在从句中不能重复其意。There are many places we can v

27、isit（them）in China.4、关系词：引导定语从句的都称关系词关系代词：who, whom, which, that, whose, as。关系副词：when, where, why。that偶尔也作关系副词。5、确定关系词的步骤（1）先找关系词，看先行词指的是什么。（2）看关系词在从句中所充当的成分。6、在定语从句中，当先行词指物时，下列情况的关系词宜用that而不用which（1）先行词被形容词最高级 序数词 数词几种词修饰或被 only、any、few、little、no、all、one of等修饰时。（2）先行词为all、much、little、none、few、one、s

28、omething、anything等不定代词时。（3）先行词中既有人又有物时。He was looking pleasantly at te children and parcels that filled his bus.（4）先行词在主句中作表语关系词在从句中作表语时。The village is no longer the one that was 5 years ago.（5）当主句中含有疑问词which时。Which are the books that you bought for me ?7、宜用which而不用that的情况（1）在非限制性定语从句中（2）在关系词前有介词时（3

29、）当先行词本身是that时（4）当关系词离先行词较远时8、关系词who与that指人时，也有不同情况分别用不同的关系词（1）当主句是there be句型时，关系词用who。（2）先行词是为anyone、those、someone、everyone、one等词时，关系词用who。（3）当主句是who作疑问词时，关系词用that。Who is that girl that is standing by the window?（4）whom在从句中只作宾语，可被who取代。9、whose作关系词既指人又指物，在从句中作定语。如：Do you know Mr.Smith whose story is

30、very moving ?There is a room, whose window faces the river.There is a room, the window of which faces the river.10、关系代词as,在从句中作主语、宾语和表语。（1）先行词被such和the same修饰，或句型as many（much）中，从句都用as 引导。Such books as you bought are useful.The school is just the same as it was 10 years age.注意：区别such that 引导的结果状语从句。They are suchlove
