内蒙古翁牛特旗乌丹第一中学高中英语 unit4 定语从句教学案1 新人教版必修5.doc

课题语法1：定语从句的基本用法（the basic usages of the attributive clause）课型新授课教学目标：1、了解定语从句的位置、结构以及翻译； 2、学习并掌握定语从句的规则，尤其是关系代词的选择教学重点：1、定语从句，先行词以及关系代词的概念； 2、关系代词的选择。教学难点：利用定语从句书写长句教学内容： 自学探究：（p90-91 in the textbook）1. 定语从句的结构公式是？2.引导定语从句的关系词有几类，具体包括哪些词？3.定语从句的关系引导词在从句中具体做什么成分？4.that在定语从句中存在省略的情况吗？若有，在什么情况下省略？5.根据定语从句的作用大小可以把定语从句分为哪两类？具体如何区分？6.引导定语从句的关系词有时会用“介词+关系代词”，其中的关系代词具体指哪几个词？定语从句及专项练习（学生案）语法解释： 定语从句：修饰名词或代词的从句。换句话说，名词、代词后的从句叫定语从句。 先行词：被定语从句修饰的名词、代词、甚至词组或句子叫先行词。 关系词：引导定语从句的词叫关系词。 关系词分两种： 一是关系代词(在定语从句中担任主、宾、表、定语成分) 二是关系副词(在定语从句中担任状语成分) 关系词的三个功能： 1. 连接功能（连接先行词与定语从句）； 2. 担任功能（在定语从句中担任主、宾、表、定、状语）； 3. 替代功能（在定语从句中代替先行词）。 a plane is a machine. the machine can fly. a plane is a machine, and the machine can fly. a plane is a machine that can fly. 关系代词有：who, whom, whose, that, which 可担任主语的是： who, that, which 可担任宾语的是： who, whom, that, which 可担任定语的是： whose, which 当先行词是人时，可用的关系词是：who, whom, that 当先行词是物时，可用的关系词是：which, that, whose 关系副词有：when (先行词为时间), where (先行词为地点), why (先行词为原因) 关系副词 = 介词 + which / whom 定语从句分为两种：限制性与非限制性。 先行词与关系词之间无逗号隔开为限制性；有逗号隔开则为非限制性。 非限制性定语从句一般不可用关系代词that引导。 以下练习详细介绍了定语从句使用的具体规则（学生案）参考答案选择aaabc bbabc adc 填空1. when 2.whose 3. which 4. that 5.
