3、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 visit（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
4、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 被 only、any、few、little、no、all、one of等修饰时。（2）先行词为all、much、little、none、few、one、something、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 wa

6、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 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 man
7、y（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 such lovely children that we love them much.the same that 引导定语从句。 I want to use the same tool that you used just now.（2）无先行词的定语从句用as和which引导。区别：意义上：as 含有“这点正如

9、、reason、time时，可用that作关系副词。（非正式场合）I dont like the way that / in which / he talks.当time作先行词时，关系词可以省掉。This is the first time I have given you a lesson in French. 12、必须注意的问题 （1）关系词作主语时，从句中谓语的数。 （2）注意区别定语从句与强调句。 定语从句中关系词作从句成分，复合句。 强调it无意义，that / who不是引导词。 强调it is / was和that / who后如果句子意思讲得通则是强调句，讲不通则不是。 I
10、t is the museum that / which we visited last year.(定语从句) It was in the hotel that we stayed last night.（强调句） （3）定语从句与同位语从句的区别。 定语从句引导词被称为关系词，that充当主语、宾语、表语。有时可省略。 同位语从句引导词被叫做连词，that不能充当任何成分，不可省。 Word came that their army was defeated.(同位语) We expressed to them our wish that was the same as their.(定语

17、 our wish that was the same as their.(定语)三、例题精析【例题1】The film brought the hours back to me _ I was taken good care of in that faraway village. A. until B. that C. when D. where【答案】C【解析】本题考查分隔定语从句的关系词的选择。作好本题的关键是要能辨认出该定语从句的先行词the hours和关系词被介词短语to me所分隔。定语从句的先行词是表时间的名词hours, 并且关系词在从句中用作状语，故应选择表示时间的关系副词
18、when。【例题2】_ is known to everybody, the noon travels around the earth once every month. A. It B. As C. That D. What【答案】B【解析】本题考查as引导的非限制定语从句。as作“正如”解时，引导的非限制性定语从句来修饰整个句子。当as在从句中作主语时，常用于下列短语：as is known、as is said、as is reported、as is announced等。要注意掌握作关系代词引导定语从句的用法。【例题3】After living in Pairs for fifty
19、 years he returned to the small town _ he grew up as a child. A. which B. where C. that D. when【答案】B【解析】本题考查限制性定语从句中关系词的选择。定语从句的先行词是表示地点的名词短语the small town, 且关系词不作定语从句中的主语和宾语而作地点状语，因此定语从句必须用关系副词where引导。要注意分清先行词在从句中充当的成分，然后选择适当的关系词。四、课堂运用【基础】1. Last month, part of Southeast Asia was struck by floods,
20、 from _ effects the people are still suffering. A. that B. whoseC. those D. what【答案】B【解析】本题题干中的effects和先行词floods之间有所属关系，所以要用whose，这样from whose effects一起引导定语从句。2. Mark was a student at this university from 1999 to 2003, _ he studied very hard and was made Chairman of the Students Union. A. during whi
21、ch time B. for which time C. during whose time D. by that time【答案】A【解析】通过分析属干可以知道。先行词表示的是一个时间段，且在从句中充当时间状语，根据这个意思，用“介词 + 关系代词”引导定语从句。c项中的whose不能用来指代时间。3. I work in a business _ almost everyone is waiting for a great chance. A. how B. whichC. where D. that【答案】C【解析】本题考查关系副词where在定语从句中的用法。现行词a business
22、表示地点“公司”，在定语从句中作状语，故选用where。4. The English play _ my students acted at the New Years party was a great success. A. for which B. at which C. in which D. on which【答案】C【解析】本题考查“介词+关系代词”的用法。关系代词在定语从句中作介词的宾语时。从句常常由“介词+关系代词”引出。介词的选择，取决于与现行词成从句之间的关系。“在英语剧中扮演角色”应为act in the English play，因此关系代词which前应用介词in，故
23、本题选C。【巩固】1. New York, _ I visited last year, is a nice old city. A. that B. whichC. when D. in which 【答案】B【解析】本题考查非限制性定语从句。非限制性定语从句不能用that引导；关系词在定语从句中作及物动词visited的宾语，故正确答案是B。 2. I can think of many cases _students obviously knew a lot of English words and expressions but couldnt write a good essay.A
24、. why B. whichC. as D. where【答案】D【解析】本题考查定语从句关系词的选择。本题先行词是cases，意为“个案”。从句中不缺少主语和宾语。故应用where引导定语从句且在从句中作状语。正确答案是D。3. George Orwell, _ was Eric Arthur, wrote many political novels and essays.A. the real name B. what his real nameC. his real name D. whose real name【答案】D【解析】whose引导定语从句时，只能用作定语；其他选项均不能构成
25、定语从句。【拔高】1_is reported in the newspaper, talks between the two countries are makingA. It B. As C. That D. What【答案】B【解析】引导非限制性定语从句，而且可以放在句首，这时as用作从句中的主语，代替主句的内容。如果把句中的逗号去掉，就可以选A项。2. American women usually identify their best friend as someone _ they can talk frequently.A who B. asC. about which D. wi
26、th whom【答案】D【解析】talk的意思是“交谈”，是不及物动词，后面带宾语就要带适当的介词，因为定语从句的先行词是人，一个构成talk with sb.结构，且把介词提前。 3Anyway, that evening, _ Ill tell you more about later, I ended up staying at Rachels place.A. when B. whereC. what D. which【答案】D【解析】通过分析可以知道：that evening是定语从句的先行词，但是在句子中用作介词about的宾语，所以不能用when，要用which引导定语从句。 课
