4、部美国电影是什么？ 当先行词既有人又有物时。 Do you know the things and persons that they are talking about？你知道他们正在谈论的事和人吗？ 当主句的主语是疑问词who或which时。 Which is the bike that you lost? 哪一辆自行车是你丢的？ Who is the boy that won the gold medal? 获得金牌的男孩是谁？,当先行词在主句中作表语，而关系代词也在从句中作表语时。 Shanghai is no longer the city that it used to be. 上

6、es are built close to each other. 解析 本题考查定语从句。句意：这古老的城镇拥有狭窄的街道和一些小房子，这些房子都靠得很近。本题为定语从句，且从句中缺少主语，用that/which引导。,that/which,2.关系代词who，whom和whose的用法 (1)关系代词who，whom先行词指人。who是主格，在从句中作主语，不可省略； whom/that在定语从句中作宾语时，可以省略； whose是属格，先行词既可指人，也可指物。在定语从句中用作定语，不可省略。 The man who was here yesterday is a painter. (w
7、ho在从句中作主语) 昨天在这里的那个人是画家。 I know the man whom you mean. (whom在从句中用作宾语，可省略) 我认识你指的那个人。,A child whose parents are dead is called an orphan.

9、are used in their factory. 我们已经找到了像他们工厂里用的那种材料。(as作主语) These houses are sold at such a low price as people expected. (as作宾语) 这些房子以人们所期望的那样的低价出售了。 He is not the same man as he was. 他和过去不同了。(as作表语),such.as.引导的定语从句与such. that. 引导的状语从句的区别： He is such a clever boy as everyone likes. 他是一个人人都喜欢的聪明男孩。 He is
10、 such a clever boy that everyone likes him. 他是个如此聪明的男孩以至于每个人都喜欢他。 第一个句子包含了一个定语从句，因为从句中缺成分；而第二句的从句不缺任何成分，是状语从句。,(2)as表示“正如，正像” 此时，as从句中常用know, expect, happen, point out, plan, suggest等单词或短语。 He came back home late，as we expected. 正如我们所料，他回家晚了。 As is pointed out, this is a grammar problem. 正如所指出的，这是个语
11、法问题。,(3)The new policy only covers such people have made great contributions to our country during the war. 解析 句意：这项新政策只涉及那些在战争中为祖国做出重大贡献的人们。根据句意，判断先行词为people，又因先行词由such修饰，故用as。,as,关系副词引导的定语从句,1.当先行词在定语从句中作状语时，要用关系副词，表时间用when，表地点用where，表原因用why引导 He will always remember the day when his father return
12、ed from America. 他将永远记得他父亲从美国回来的那一天。 The factory where his father works is the largest one in this city.他父亲工作的那个工厂是这个城市最大的工厂。 I dont know the reason why he was absent today. 我不知道他今天为什么没来。,2.介词关系代词 where/when/why/how when表时间的介词(in，at, during)which where表地点的介词(in，at，on, under) which why表原因的介词(如for) wh
13、ich how表方式的介词(如in)which,3.关于关系副词where 高考对于where的考查趋于复杂，从先行词为明显的“地点”转向模糊化的“地点”。实际上， where的外延已发生变化，当先行词是表示某人/物的situation或某事发展的stage时都可用where这个关系副词。 They have reached the point where they have to separate with each other.他们已经到了彼此必须分手的地步。,4.关系代词和关系副词的区别 关系代词在定语从句中作主语、宾语或表语，而关系副词在定语从句中作状语。因此在选择关系词时，最重要的是
14、分析一下定语从句中的成分。 比较： Do you still remember the days that/which we spent in Qingdao? 你还记得我们一起在青岛度过的日子吗？ Do you still remember the days when we spent the summer holidays in Qingdao? 你还记得我们在青岛过暑假的日子吗？,关系代词或关系副词的选用，关键是看先行词与从句中动词的关系：先行词是否作从句中动词的宾语或主语；将先行词带入从句中是否需要添加介词。,(1)(2013四川，9)Nowadays people are more
15、concerned about the environment they live. 解析 本题考查定语从句引导词。先行词是environment为物(抽象地点)，而且定语从句中不缺少主语， live在此为不及物动词，故选where (in which)。,where,(2)Life is like a long race we compete with others to go beyond ourselves. 解析 句意：生活像长跑比赛，我们与其他人竞争以超越我们自己。先行词为race，代入定语从句后为：.we compete with others to go beyond ourse
16、lves in the long race.由此可见，race在定语从句中作状语，且表示地点，故用关系副词where。,where,“介词+关系代词”引导的定语从句,1.“介词关系代词”引导定语从句时，关系代词只能用which(指物)或whom(指人)，当介词放在关系代词前面时， 关系代词不能省略；反之，当介词位于定语从句的末尾时，可用that/which(指物)，that/who/whom(指人)作介词的宾语，作介词宾语的关系代词可以省略。 This is the book for which you asked. (which不能省略)这是你所要的书。 This is the book which you asked for. (which可省略)这是你所要的书。,Is this the house in which Shakespeare was born? (which 不能省略)这是莎士比亚出生的房子吗？ He paid the boy $10 f
