高考英语语法专题复习：定语从句
【高考考纲解读】
定语从句的用法较为复杂，高考除了单独考查定语从句知识外，还常常结合句式结构、时态等来综合考查。纵观近几年各地高考试题，不难发现其考点主要包括：
1. 考查关系代词和关系副词的区分。如: that, which和where, when的区分; that, which和why的区分等。 2. 考查whose的使用。whose可以指代人或物, 在定语从句中作定语, 后跟名词。指物时, whose＋名词＝名词＋ of which ＝ of which＋名词。如：
The classroom whose door/the door of which/of which the door is broken is on the second floor.
3. 考查as/which引导的非限制性定语从句。尤其要重视which，as引导的非限制性定语从句和it，what引导的主语从句的区分。
4. 考查定语从句中的主谓一致现象。如：
I, who am your close friend, will try my best to help you whenever you are in trouble.
5. 考查“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，关系代词指人时用whom，指物时用which，不能用that。关系代词作定语时也可用whose。如：
The teacher in front of whose house stands a tall tree is very patient with his students.
6. 考查一些特殊的先行词。如: 当situation, point, case, activity, scene及period, festival, occasion等出现时, 要注意具体情况具体分析; 作主语、宾语和表语时, 用关系代词that/which; 作状语时, 用关系副词where/when或“介词＋which”, 表示在某种特定的情形下。
7. 考查定语从句、强调句、时间状语从句等的区别。 【命题趋势】
定语从句是历年高考的重点，主要考查常见关系代词和关系副词的用法，比如which/that/as/ when/where的用法及区别性的选择等，及与其他从句如名词性从句的区别等。在高考的中主要体现在语法填空，短文改错，完型填空等中，且完形填空80%每年会出一道题。 【名师指导】
考生在定语从句的学习过程中存在着以下几个问题： 1. 考生不能辨别定语从句的结构；
2. 关系代词与关系副词的选择混乱，不清楚关系代词与关系副词的使用情况； 3. 习惯性以翻译的方式来理解定语从句、同位语从句，而使自己陷入困境之中； 4. 由于对句型结构分析不到位，经常出现代词与关系代词错用的情况。
