5、gestudentMybrother,whois18yearsold,isacollegestudent.,我18岁的那个弟弟是大学生。,我弟弟是大学生,今年18岁。,第一句中，限制性定语从句限制了先行词的意义，明确是18岁的那个弟弟（而不是其他的，即有可能还有几个弟弟）。第二句使用了非限制性定语从句，表明可能只有一个弟弟，18岁，起补充说明作用。,非限制性定语从句,定语从句有限制性和非限制性定语从句两种。一般地说，限制性定语从句用来限制先行词的意义，与先行词关系密切，是整个句子不可缺少的一部分，否则会造成全句意义不明确。而非限制性定语从句带有补充说明的性质，与先行词之间存在一种松散的修饰关系

6、，去掉后一般不会影响句子的主要意义。概括起来，两者有如下区别：1）形式不同：限制性定语从句常紧跟其先行词，中间不用逗号隔开；而非限制性定语从句与先行词之间常用逗号隔开。,Beijing,which is the capital of China,is rich in its culture and historic relics(遗迹).,如果先行词是专有名词或独一无二的人或物，通常用非限制性定语从句。,Hismother,wholovedhimverymuch,diedin1818.最爱他的母亲于1818年去世了。,IliketochatwithJack,whoisacleverboy.我喜

8、onallyIdoubtedverymuch.凯罗尔说工作可在10月前完工，这一点我个人深感怀疑。Ashasbeenannounced,weshallhaveourfinalexamsnextweek.(2003上海春)我们将于下周举行期末考试，这一点刚才已经宣布了。句中as是关系代词，引导非限制性定语从句，指代后面整个主句的内容。,在限制性定语从句中，关系代词如果充当从句的宾语可以省略；Isthisthebook(that/which)youarelookingfor?这就是你要找的那本书吗？（关系代词that/which充当从句的宾语，可以省略）,而非限制性定语从句中的关系代词是不能省的。

9、Theresultoftheexperimentwasverygood,whichwehadntexpected.实验的结果非常好，这简直出乎我们的意料。(关系代词which在从句中充当expect的宾语，但因为引导的是非限制性定语从句，所以不能省略),译法不同,：把句子翻译成汉语时，限制性定语从句中，通常先译从句后译先行词；而非限制性定语从句中则往往相反。Wearelivinginanagewhenmanythingsaredoneoncomputer.(2003北京春)我们生活在一个许多工作都由电脑来完成的时代。Wewillbeshownaroundthecity:school,museu

10、msandsomeotherplaces,whereothervisitorsseldomgo.(2002北京)我们将被带去参观全市各地：包括学校、博物馆和其它场所，那些其它游客很少去的地方。,要点,表示“补充说明”常用“，”隔开连词不用that连词不能省略which在句中可以指代前面整个句子 As在句首指代整个句子,关系代词which 和 as 的区别,1.Which引导的从句不能放在主句前，而as引导的从句则既可以放在主句前，也可以放在主句后。,As is often he case,he is absent.Which is often the case,he is absent,He

11、saw the girl,as he had hoped,He saw the girl,which he had hoped,He is a foreigner,as I know from his accent.He has to work on Sundays,which he doesnt like.,As 和 which 都可以指代一个句子，但as 有“正如”，“就像”之意，which 则没此含义。,正如预料的那样，比赛棒极了。,The match was wonderful,as we had expected,众所周知，台湾是中国的一部分。,As we all know,Taiw

12、an is a part of China.,As is known to all,Taiwan is a part of China.,她嫁给了他，这是出乎预料的。,She married him,which was unexpected.,Dont read such books as you cant understand.,He is not such a fool as he looks.,他貌似憨傻，实则不然。,as anybody can see 正如人人都能看到的那样as often happens 正如经常发生的那样。as we(all)know as is known to
