一、定语从句“口诀一”详解定语从句真奇妙,关系代(副)词来引导,定语从句分两种,是否限定看逗号。
该口诀的意思是,定语从句由关系代词(which, that, who, whom, whose)和关系副词(w here, when, why)来引导。
请同学们牢记这8个词。
定语从句分“限制性定语从句”和“非限制性定语从句”两种,前者表示与主句的关系比较密切,它说明先行词的性质、身份、特征等状况。
如果去掉,则会影响句子意思的完整。
后者表示与主句的关系不十分密切,只是对先行词作些附加说明而已。
如果去掉,主句意思仍然清楚完整。
它跟主句之间常用逗号分开,翻译时通常不译作定语,而是单独译成与主句并列的句子。
请比较:Tom is a boy who often helps others.汤姆是一个经常帮助别人的男孩。
(who ofte n helps others是限制性定语从句。
如果去掉,Tom is a boy.这个句子就没什么意义。
)Yesterday I met Tom, who seemed a little upset. 昨天我见到了汤姆,他看起来有点心烦意乱。
(who seemed a little upset是非限制性定语从句。
如果去掉,Yesterday I met Tom.仍有意义。
)又如:A doctor is a person who looks after people's health.医生就是负责人们健康的人。
This is the diamond which the lady has lost.这就是那位女士丢失的钻石。
The school where I studied for only two years was three kilometers away. 我学习了仅两年的那所学校离家3公里远。
I still remember the time when I first traveled by plane.我仍然记得第一次坐飞机旅行的时间。

定语从句whowhomwhichwhose区分
定语从句是英语语法中比较重要的一部分,它可以通过引导词来确定其修饰的名词或代词。
其中,who、whom、which、whose是最常见的引导词,但是它们的区别也是很多人容易混淆的。
下面将分别介绍它们的用法:
1. who:用来引导指人的定语从句,作主语或宾语。
例如:The girl who is standing there is my sister.(站在那里的女孩是我的妹妹。
)
2. whom:用来引导指人的定语从句,作宾语。
例如:The man whom you met yesterday is my boss.(你昨天见到的那个男人是我的老板。
)
3. which:用来引导指物的定语从句,作主语或宾语。
例如:The book which I bought yesterday is very interesting.(我昨天买的那本书非常有趣。
)
4. whose:用来引导指人或物的定语从句,表示所属关系。
例如:The girl whose mother is a famous actress is very talented.(那个女孩的母亲是一位著名的演员,她非常有才华。
)需要注意的是,在口语中,有时who和whom可以互换,而which 则不太会用来修饰人。
此外,定语从句中的引导词也可能被省略,这时需要根据上下文来确定其指代对象。
