1、高三英语语法专题讲练定语从句编制人： 审核人： 序号：4 班级: 姓名: 小组:一 定语从句的基本概念1. 定语从句：修饰一个名词或代词的从句称为定语从句，一般紧跟在它所修饰的先行 词后面。2. 先行词：被定语从句修饰的那个名词或代词称为先行词。3. 关系词：引导定语从句的关联词称为关系词。关系词有关系代词和关系副词。关系代词：who, whom, whose, which, that, as等；关系副词：where, when, why等。关系词常有三个作用：引导定语从句；代替先行词；在定语从句中充当一个成分。Harry Potter is the most interesting nove
2、l that I have read. (that I have read是定语从句；novel是先行词；that 是关系代词，代替先行词novel，在从句中作have read的宾语。)二 关系代词as引导的定语从句限制性定语从句形式上不用逗号和主句隔开，是先行词不可缺少的部分，去掉它主句意思往往不明确，翻译成先行词的定语，“的”。非限制性定语从句是先行词的附加说明，去掉了也不会影响主句的意思，它与主句之间通常用逗号分开，通常翻译成主句的并列句。that不能引导非限制性定语从句。1）当先行词为整个句子时，只能用非限制性定语从句。引导这类从句的关系代词只有as和which。as引导的非限制性定
3、语从句位置灵活，可置于句首、句中和句末，译作“正如，正像”。而which引导非限定性定语从句不能置于句首，译作“这”。常用形式：as we can see(正如我们所看到的),as we had expected(正如我们所预料的),as is often the case(情况常常如此),as is reported in the newspaper(正如报纸报道的那样),as is well known/as we all know(众所周知),as the saying goes(俗话说)等。2）as也可以引导限制性定语从句，常用于下列句式： such + 名词+ as the same
4、 + 名词+ as ；Shemustpayforwhatshehasdone,which/asisnatural.She, as we all know, can speak three foreign languages.As was pointed out, this kind of substance(物质) is poisonous.This is the same book as I lost yesterday. ( the sameas 表示与同样，但不是同一个)This is the same book that I lost yesterday. ( the samethat
5、 表示同一个，就是那一个)三“介词关系代词”引导的定语从句“介词关系代词”引导的定语从句，关系代词一般只有which，whom。先行词是物时，用which，先行词是人时，用whom。that与 who 不能用在介词后。介词的选择1） 依据定语从句中动词与形容词的搭配习惯来确定。I bought a great many books, on which I spent all my money that I saved. (spend on)Ours is a beautiful country, of which we are greatly proud. (be proud of)2) 依据
6、与先行词搭配的具体意义而定。Ill never forget the time during which I spent my childhood in the country.3）“名词/代词+ of + 关系代词”结构在非限制性定语从句中，要表示先行词的一部分时，可以用“名词/代词+ of + 关系代词”的结构。常见的有some/ several / a few/ a little/ many/ more/ most/ the largest of which/ whom等形式。There are 50 students in our class, two-thirds of whom h
7、ave been to Beijing.He paid the boy10 for washing ten windows,most of which hadnt been cleaned for at least a year4）whose 引导的定语从句可以转换为“of + 关系代词”They live in a house, whose door opens to the south. = They live in a house, of which the door opens to the south. = They live in a house, the door of whic
8、h opens to the south.四关系副词where ,when和why 引导定语从句的关系副词除了起连接先行词和从句的作用外，它们还有一个重要的作用，那就是在定语从中充当成分。具体地说，关系副词在定语从句中作状语。因此在选择引导词时，如果从句中不缺主语或宾语，那么一定用关系副词；在实际的运用中，when 相当于on /in / at/ during which， where 相当于in/ at/ on/ under which ，why相当于for which。1.
