江苏省扬州市田家炳实验中学高中英语必修二 M2U1 Grammar 精品

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。
