2014年高二英语（人教版选修7）教学精品课件：UNIT 2 PERIOD Ⅲ.ppt

1、教师用书独具演示教学目标1熟记学案中所列出的单词和短语。2通过学案中所给出的重点单词和重点短语的学习，让学生能够正确理解和使用这些单词和短语，能够运用这些词语造句。3通过对语法的教学让学生能够理解并能够运用这些语法知识，弄清楚动词不定式的被动式的形式和用法。教学地位本单元的语法是不定式的被动式，分为一般式和完成式，学生可能会感到比较难以掌握。让学生正确理解和掌握语法知识是让学生学好英语的关键，所以应给学生创设一个语境，让学生理解该语法的应用，而不要让学生死记硬背语法条文，应从理解的基础上去运用这些语法。新课导入建议通过对学生作业的检查导入本堂新课。演示结束1He felt happy when
