3、句中有三大作用：1）连接作用：连接主句与从句。2）成分作用：在定语从句中充当一个成分。3）替代作用：替代某一名词代词或某一句话。主语 宾语 定语指人 who/that whom/who/that whose指物 which/that which/that whose The boys who are playing football are from Class One.正在踢足球的男孩们是一班的。The man（whom/who/that）you met just now is my old friend.你刚才遇见的那个人是我的老朋友。The number of people that/w

4、ho come to visit the city each year reaches one million.每年来游览这座城市的人数达到一百万。I once lived in the house whose windows were much larger than usual.我曾经住在那个窗户比一般窗户大很多的房子里。as 引导限制性定语从句as 既可指人也可指物。在定语从句中可作主语或宾语。它常用在such.as.，the same.as.等结构中，as 不能省略。Such reasons as we give can persuade him to give up this foo

5、lish plan.我们给出的这些理由可以说服他放弃这个愚蠢的计划。as 引导非限制性定语从句as引导非限制性定语从句，代替整个主句的内容。从句可放在主句前、主句后或主句中间。as 引导非限制性定语从句常用的固定表达：as we all know 众所周知 as is well known 众所周知 as you see 如你所见 as we expect 正如我们预料的那样 as often happens 正如经常发生 as I can remember 正如我所记得的 as has been said before 如前所 as is/was expected 正如预料的那样 as ca

6、n be seen 正如所见 as is often the case 情况常常是这样 As is often the case，girls like dolls while boys like guns.女孩喜欢玩具娃娃而男孩喜欢枪，这是常见的情况。关系代词as 与which 引导的非限制性定语从句，其先行词都可以是整个主句，as/which 指代整个主句的意思。但as 和which 具有不同的词义、句法和用法。as 引导的定语从句表示说话人的看法、态度、解释或评论。as仍具有“正如，像，由可知”等意思，翻译时有时可不必译出。as 引导的此类从句可置于句首、句中或句尾。As Napoleon

7、 once said，attack is the best method of defense.拿破仑曾经说过，进攻是最好的防御。which 引导的定语从句对主句所叙述的事情进行补充说明，表明事物的状态或结果。which 此时指前面主句所提到的这件事，常译为“这一点，这件事”等。这时它引导的从句与主句之间常含有并列、因果关系。它引导的从句的位置不像as 引导的从句那样灵活，只能位于主句的后面。He changed his mind again，which（=and that）made us all angry.他又改变了主意，这使我们大家都生气了。关系副词的基本用法关系副词的基本用法地点状语

8、where 时间状语 when 原因状语 why（1）when 引导的定语从句修饰的先行词是表示时间的词，如 time，moment，month，day，year 等，when 在定语从句中作时间状语。We dont know the exact time when he will return.（He will return at the time.at the time 作时间状语）我们不知道他回来的确切时间。（2）where 引导的定语从句修饰的先行词是表示地点的词，如school，house，place，village 等，where 在定语从句中作地点状语。She worked in

9、 Japan for a few years where she taught English.（She taught English in Japan.in Japan 作地点状语）她在日本工作了几年，在那里她教英语。（2）where 引导的定语从句修饰的先行词是表示地点的词，如school，house，place，village 等，where 在定语从句中作地点状语。She worked in Japan for a few years where she taught English.（She taught English in Japan.in Japan 作地点状语）她在日本工作了

10、几年，在那里她教英语。1.当先行词是表示地点的名词，如 place，room，airport 等，同时关系词在从句中作地点状语时，定语从句需用关系副词where 引导。2.如果先行词是表示抽象意义的地点名词，如 case，situation，condition，job，career，point 等，其后的关系副词也用where。The boss of the corporation is trying to create an easy atmosphere where his employees enjoy their work.公司老板正尽力创造一种轻松的气氛，在这种气氛中，员工喜欢他们的

11、工作。（3）why 修饰表示原因的词，在定语从句中作原因状语。Tell me the reason why you were absent yesterday.告诉我你昨天缺席的原因。“介词介词+关系代词关系代词”引导的定语从句引导的定语从句要掌握“介词+关系代词”引导的定语从句，我们要注意以下两点：（1）关系代词的选用在介词后作宾语的关系代词一般只有which，whom 和whose。如先行词是物，引导词用which；如先行词是人，引导词用whom；whose 适用于两者，但要注意whose 后面有它所修饰的名词或代词，因为whose 在定语从句中起到形容词的作用。The boss in w

12、hose company I worked for 10 years has retired.我供职十年的那家公司的老板退休了。（2）介词的选用 根据从句中谓语动词的搭配习惯。This is the book on which I spent 10 yuan.（spend与 on 搭配）This is the book for which I paid 10 yuan.（pay 与 for 搭配）这就是我花10 元买的那本书。根据先行词的搭配习惯。I still remember the day on which I first came to this school.我仍然记得我第一次来这所
