1、模块2第一单元Grammar and usage-现在完成时与现在完成进行时 一、教材分析：本节课是模块2第一单元的语法内容-现在完成时与现在完成进行时， 该部分是高中语法的一个重点内容。 学生对该内容半知半解， 运用不准确， 尤其易与一般过去时混淆， 加上语法课易让人觉得枯燥， 学生对此有一定的畏难甚至排斥心理。 二、学情分析： 时态是每年高考必考内容， 而从平时的翻译句子和书面表达上可以看出， 学生就这方面的知识掌握不太到位， 现在完成时和一般过去时更是时态题目中的高频错题。 根据这些特点， 我采用与新课标要求相一致的教学方式， 在师生互动的过程中来实现教学任务和目标。三、教学设计的结构及
2、设计理由： 本节课的教学应以学生为中心， 以抛出问题为出发点， 让学生自主地进行讨论， 对信息进行加工， 归纳出每一部分的重点。现在完成时、现在完成进行时、一般过去时等时态， 学生都不陌生， 只是对概念的准确运用还不到位。用时间轴、不同例句的对比， 能更形象、更直观的让学生理解。 教师在教学过程中起一个引导、启发、帮助作用。在教学过程中通过时间轴、小图片等形式， 让学生能更直观地理解不同时态的用法， 掌握它们的区别， 最后进行归纳总结。课 题 M2 Unit1 Grammar 班 级高一（ ）姓 名授课日期 年 月 日Learning Aims:1.复习现在完成时的基本用法。2.区别现在完成时
