An alysis of the Teach ing Material 教材分析
Gen erally speak ing, grammar is a real headache for most of stude nts for it is very boring and difficult. Attributive clause, one of the most important grammar in Senior English, is no exception. The grammar of Unit 5 in Book 2 further discusses attributive clauses that contain prep. + whom/which.
As mentioned above, grammar is very difficult. To solve this problem, I will ask stude nts to do abundant exercises in order to let them master it easily.
