1、全国通用2012届高考英语一轮语法专题复习：定语从句,定语从句的考查在高考中主要出现在单项填空部分。 1.主要考查的知识点： (1)关系词的选用 (2)关系词前加介词等的用法 (3)定语从句的时态 (4)非限制性定语从句的用法,复习重点： (1)关系代词和关系副词的用法区别。 (2)掌握只能用that引导定语从句的情形。 (3)掌握介词加关系代词的用法。 (4)掌握as和which引导非限制性定语从句的用法。 2.如何应对定语从句的考查 解题时，首先要确定先行词，根据先行词在从句中所作的句子成分来判断该用关系代词还是副词，并且确定具体用哪个关系词。如果从句中谓语动词为不及物动词，应考虑关系代词
2、前该不该加介词。,(2010)Ive become good friends with several of the students in my school _ I met in the English speech contest last year. A. who B. where C. when D. which 思路点拨：首先确定先行词，根据空格后的从句I met in the English speech contest last year缺少met的宾语，该宾语应当为sb.，故可判断先行词不是从句最靠近的my school，而是被in my school所隔开的the stud
3、ents。故此，关系代词该用who/whom或者省略。四个选项中，只有A选项正确。,1.定义：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。如： Harry Potter is the most interesting novel that I ha
4、ve read. 分析：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。,4. 限制性定语从句和非限制性定语从句 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。关系代词that和关系副词why不能引导非限制性定语从句。,His brother who is now a lawyer always encourag
