定语从句教学设计Thoughts on the design:本节课的设计重点在于让高三学生复习已学的知识，查缺补漏，理清定语从句的知识体系。Teaching objectives:1. to help Ss review the functions of relative pronouns and relative adverbs;2. to help the students be able to use attributive clauses well.Key Points and Difficulties Points介词+which /whom 用法, as 的使用Teaching procedures:Step 1. 复习限定性定语从句思路缺主语： which, that, who缺宾语：which,that,who,whom缺意思：whose,where,when,why, 介词+which /whom介词+which /whom的做题思路是将先行词还原到定从句中，再翻译。Step 2. As在限定性定从中用法满足两个条件才能使用as：1. 定语从句中缺少主语或宾语2. 先行词前有so，such，the same，或是as修饰例句：I seldom give my students so difficult a problem as they cant work out.
