初中Section A教案配套课件ppt

Period 2 （Section A 3a-4c）

设计说明

　　3a-3c：由展示图片和提问导入故事情境。在师生互动交流的过程中，可呈现部分新单词和短语。3a是节选了《鲁滨逊漂流记》的片段。首先让学生带着3a中的问题阅读课文，找出答案；然后再细读文章完成3b中的任务。在学生再次读课文后，让其合上书，由老师将3c中的句子念出，学生逐句修正，在检查学生对文章的理解把握情况的同时，培养学生的听说能力。

　　Grammar Focus-4c：复习现在完成时的句式结构及所表达的意义和功能，引导学生将不规则动词的变化归类，便于学生记忆。通过练习，教会学生正确使用现在完成时与一般过去时。活动4b提供了一篇短文，要求学生在更为复杂的语境中合理运用一般现在时、一般过去时、一般将来时和现在完成时，用所给动词的正确形式填空。
