4、充当句子成分。选择关系词的两条重要依据: 先行词是人还是物；在从句中作何种句子成分。3. 关系词的选择与作用从句中作用指人指物主句整句主语Who thatWhich that ,as 或As., ,which(置主句后)宾语Who whom that prep.+whomWhich that prep.+which,as 或As., ,which(置主句后)定语Whose Whose of which时间状语(指at the time /in the year /on the day)when , at/in /on which地点状语(指at /in the place )where, at
5、 /in which原因状语(指for the reason)why, for which方式状语(指in this /that way)in which, that 或不填4. 关系词的特殊用法（1） 只能用that ,不能用which 的情况a. 先行词是指物的all, little , much , few, everything , anything, nothing, none 等不定代词时b. 先行词被all, every, any, much, little , few, no 等词修饰时c. 先行词被序数词或形容词最高级修饰时d. 先行词被the only, the very(
6、正是，恰是), the same , the last 修饰时e. 先行词既指人又指物时。f. 当主句是以which, who, what 开头的特殊疑问句时，引导定语从句的关系代词一般用that（2） 不用that 的情况a.在引导非限制性定语从句时;介词后不能用。 （可简单记为“前有介词和逗号， 不能用that.） (3)关系代词as 的用法只能用按时引导的非限制性定语从句:a置于句首时，非限制性定语从句只能用as引导；_ is known to everybody, the moon travels around the earth once every month.b在the same
7、as结构中，“像那样的”Chongqing is not the same city _ we have seen in other place.c在结构as as中，“像那样的”No period in history has had as many important changes_have taken place in the last century.d在结构such as中，“像一样”I hope to get such a dictionary _he is using.（4）“介词+关系代词”引导的定语从句在“（名词，数词，代词+）介词+关系代词”引导的定语从句中， 关系代词只
8、能用whom(指人)和which（指物）。先行词指人时，用whom, 先行词指物时用which. 在这种结构中 ， “介词”的选择可依据以下几点：a. 介词与定语从句中的谓语动词是一种固定搭配。b. 看句中需用哪个介词句意才符合逻辑。例如：表示“所有关系”或整体中的一部分时常用of. c. 介词与定语从句中的形容词一起构成固定搭配，如be proud of 为固定词组。 (5) 如果先行词是way, 可用that, in which 引导定语从句，或不用关系代词。 Eg: I dont like the way that he spoke to me. =?三易混点举例1. 关系词在定语从句中
9、充当主语，宾语还是状语（1） I live in Guangzhou _is in the south of China. （2） Ill go to Beijing _my uncle works and lives. （3） Ill never forget the day _I spent with my friends in the country. . （4） I still remember the day _I stayed in the country with my friends. 当先行词是表示时间、地点或原因的词语时, 不一定填关系副词when, where, why,
10、 需要弄清所缺的关系词在从句中的作用才能选择恰当的关系词。需要牢记的是：关系副词在定语从句中只能做状语，即使先行词是表示时间，地点的名词，但如果所缺关系词在从句中是做主语，宾语的话，仍然要用关系代词which, that. 四强化训练1. This is the place _I once lived. 2. This is the place _I visited yesterday. 3. He is the second comrade _I have ever worked with. 4. The last place _we visited was the Great Wall.
