Grammar教学设计及教案分析

虚拟语气在if条件句和wish从句中的探究

教学目标

1. 产生对虚拟语气的探究愿望。

2. 初步了解虚拟语气在非真实if条件句中和wish从句中的结构及用法。

3. 能利用所提供的语境用虚拟语气完成初步任务。

教学重点及难点

1. 虚拟语气在if非真实条件句和wish从句中的结构特点。

2. 针对三种不同时态的虚拟语气构成。

3. 如何应用所学规则分析句子，并采用恰当的虚拟形式。

学情分析

虚拟语气这一部分的内容对于学生来说是一大难点。相对来说语法规则比较复杂，学生需要记忆的条条框框较多，需要针对不同的语言环境做出灵活应变的东西也比较多。所以在学生理解语气特征的基础上，老师做出全面简洁有效的总结，帮助学生记忆规则，再通过适当练习指导学生加以应用。最后巩固知识达到最终掌握知识的目的。

教材分析

虚拟语气是选修六的语法教学难点。虽然在以前的学习材料中曾出现过if引导的虚拟语气，但当时只要求学生理解该句型结构的意义。而选修六的第一、二单元则要求学生掌握if引导的三种虚拟形式并运用该结构进行创造性或半创造性的活动。

教学过程

教师活动

Step1 Lead-in

Introduce Helen Keller first.

( Helen Keller is a great writer and educator. She lost her sight when she was 19 months. Luckily she met a great teacher when she was 7 years old. She graduated from the university with the help of her teacher. Then she devoted herself to the disabilities. Her several books have influenced people a lot especially the book three days to see )

Step2 Learning Show students some sentences from the book three days to see.

been ill when I was 19 months!

If I had the power of sight for three days now, I should call to me my dear friends and look long into their faces! If I had the power of sight for three days now, I would let my eyes on the face of baby so that I could catch a vision of eager, innocent beauty! I wish I had the power of sight for three days!

If I had my life to live over after my death, I might seize every minute! If I had my life to live over after my death, I would more appreciate the joys of sights, the joys of sound! I wish I would have my life to live over after my death!

教学反思

本节课通过不同的问题创设，让学生在小组活动中通过合作和探究来完成各个任务。教学设计整体来说思路比较清晰，首先，从选材来说，我利用了学生熟知的人物及其文章为学生对非真实条件句的理解作了很好的铺垫。第二，在学生水平参差不齐的情况下，通过反复读句子，配合多媒体加上适当的中文支持，使每个学生都能准确理解当天内容。第三，教师逐步引发学生的思考，问题设置有层次有梯度，环环联系比较紧密，有利于学生的探究。最后的练习也延续了开始的话题及对仗句式，让学生有一气呵成的感觉。

但在实际操练过程中，仍然存在着很多问题。第一，学生的探究过程明显不够，教师仍急于求答案而忽略了探究本身的过程，导致有一部分同学没能完全找出规律来。第二，因为时间关系发现操练明显不够。大多数学生离开课堂之后并没有多少听说英语的练习机会，他们十分缺少环境英语的反复刺激。因此，在学生进行活动时，应尽量给学生更多的帮助，主动了解学生的语言困难。学生在有限的课堂中学到的知识毕竟有限，让他们掌握语言的同时，将课堂学到的知识内化为能力，继而实现语言学习并运用的目的提升学生的能力。
