Analysis Of Teaching Material 1. 教材以“制度”为话题，以谈论允许做某事和同意或不同意做某事为交 际功能，重点在这些语境中学习和运用情态动词的被动语态。它和前两个 单元一般现在时、一般过去时的被动语态相得益彰，共同完成了初中阶段 被动语态的学习。 2. 理解、掌握和运用情态动词的被动语态。情态动词被动语态中 be 动词 的用法是最容易出错误的地方，要引起足够的重视。 Analysis of the Students 在我们农村学校普通中学初中阶段的英语教学中，约有 25%30%的学生 无法适应这一阶段的外语学习。他们外语学习能力薄弱，外语成绩低下， 一上英语课就心情烦燥，思维抑制，继而放弃外语学习，两极分化现象由 此产生。因此,要加强学法指导和差生转化。在学习知识的过程中，提示学 生用科学的学习方法。课前预习，上课认真听讲记好笔记，课后能主动复 习，驾御遗忘规律，形成一定的记忆方法并注重知识的联系、比较，使其 具备一定的思维辨别能力。在教学中借助分组方式，提倡优生带动差生， 互相团结协作，形成良好的学习环境，使每一位学生都能往上跳一跳。 Knowledge and skills 1.Getting to know the structure of passive voice with modal verbs. 2.Learn how to rewrite sentences using passive voice with modal verbs.
