高一英语重点语法总结
限定性定语从句
1、定义:在复合句中,修饰某一名词或代词的从句叫做定语从句。被定语从句所修饰的名词或代词叫先行词。定语从句一般放在先行词的后面。引导定语从句的词有关系代词that, which, who ( 宾格whom, 所有格whose)和关系副词where, when,关系代词或关系副词放在先行词和定语从句之间,起联系作用,
同时又作定语从句的一个成份。
The man who lives next to us sells vegetables. 住在我的隔壁的人是卖菜的。
在该句中the man 是先行词,who 是关系代词,引导定语从句who lives next to us.在定语从句中,who 作主语。
2、由关系代词who, whom, which, that引导的限定性定语从句。
1)如果先行词是人,则用关系代词who/that; 如果先行词是物,则用关系代词which/that。
The number of people who/that lost homes reached as many as 250,000.
无家可归的人多达25万。
It sounded like a train that was going under my house.
它听起来就像是在我的房子下行驶的一列火车。
2)关系代词who, whom, which, that既起联系作用,引导定语从句,使之同它句中的某个名词/代词发生关系,同时又充当定语从句的一个成份。(如作从句中的主语或宾语)。当它们在从句中作宾语时,常可以省略。
The boy(who/whom/that)we saw yesterday was John's brother.
我们昨天见到的那个男孩是约翰的兄弟。
The car (which/that)my uncle just bought was destroyed in the earthquake.
我叔叔刚买的那辆汽车在地震上毁坏了。
说明:
关系代词whom用来指人,是宾格,常用在书面语中作定语从句的宾语。在口语和非正式文体中,常用who/that来代替whom或省略,如例句4。
3)当关系代词that或which修饰事物,作介词宾语时,如果介词位于关系代词之前,则用which(不能省)而不用that。
The tool with which he is working is called a saw = The tool(that/which)he is working with
is called a saw.他干活的那个工具叫锯子(不说"with that")
The factory in which his father used to work was closed last month = the factory
(that/which) his father used to work in was closed last month.
他父亲以前工作过的那家工厂上个月关闭了。
说明:含有介词的短语动词一般不拆开,介词仍放在动词的后面。
Is this the watch (which/that)you are looking for? 这是你正在找的那块手表吗?
The babies(whom/that)the nurses are looking after are very healthy.
那些护士正在照顾的宝宝们非常健康。

限制性定语从句与非限制性定语从句的区别
定语从句分限制性定语从句和非限制性定语从句,归纳起来,二者有以下几点不同:
一、作用不同
限制性定语从句与先行词的关系非常密切,是先行词不可缺少的定语,它所修饰的词代表一个(些)或一类特定的人或物如果删去,全句的意思就会变得不明确。而非限制性定语从句在意义上是先行词的一个附加修饰语,对先行词只起进一步补充说明的作用;若把它去掉,全句意思仍然清楚。例如:
The girl who stood in the corner just now is my younger sister.
刚才站在角落里的那个姑娘是我的妹妹。
Mary Smith,who is in the corner, wants to meet you.
玛丽·史密斯在那个角落里,她想见你。 毕业论文http://www.751com.cn
第一个例句中的定语从句指明作为主语的“姑娘”不是任何一个,而是在角落的那个。如果去掉定语从句,表达的意思就不明确。第二个例句已经表明主语是谁,定语从句只不过是补充说明一点情况而已。若去掉从句,句子意思仍然完整。
二、形式不同
非限制性定语从句与先行词之间通常有逗号而限制性定语从句与先行词之间则无逗号。例如:
He’s the man who lives next door.
他就是住在隔壁的那个人。(从句不可少,从句前无逗号。)
His wife,whom you met at my house,is a teacher.
他的妻子是一位老师,你在我家曾见过她。(从句可有可无,从句前有逗号。)
三、含义不同
限制性定语从句有涉他性;非限制性定语从句有唯一性。例如:
In the class there are ten students who speak English very well.
这个班上有十名英语说得好的学生。(暗示班上不只是十个学生。)
