对于案例分析高中英语语法：“虚拟语气”教学方案分析科研方法和

一、案例背景

本节课是以学生为出发点，采用任务型教学方法，自主、合作学习方法，对学生进行知识与能力的培养。“新课标”倡导任务型教学途径，即根据学习内容设计各种交际任务，让学生通过完成这些任务进行学习，学会用英语做事，以培养学生综合运用语言的能力。任务型教学认为课堂教学要有真实的生活特征，本单元语法“虚拟语气” 适合于创设各种情境，从而能够激发学生的兴趣和引起其主动参与语言实践活动的。基于这一特点可以把教材拓展到学生生活实际，实现教学的生活化，实用化。因此在本节课中以虚拟语气的含义和构成为主线，创设不同的情境，在不同语境中使学生通过交流合作达到对虚拟语气的掌握。

Grammar： 虚拟语气（2）

三、教学过程及分析

Step1 Warming up
Ask the students to go back to Page 10 and study of list poems， Poem C Our First Football Match and translate it into Chinese， paying special attention to its verb forms：
We would he won ……
If Jack had scored that goal，
If we’d had just a few more minutes，
If we had trained harder，
If Ben had passed the ball to Joe，
If we’d had thousands of fans screaming，
If I hadn’t taken my eye off the ball，
If we hadn’t stayed up so late the night before，
If we hadn’t taken it easy，
If we hadn’t run out of energy，
We would he won……
If we’d been better！
分析：学生在Unit1已经了解到英语的动词一般有三种不同的语气：陈述语气、祈使语气和虚拟语气。学习了虚拟语气两种形式：①虚拟语气出现在if引导的条件状语从句一般现在时里的用法；②虚拟语气出现在动词wish后的宾语从句里的用法。而本单元出现的虚拟语气的时态用法是学生没有具体接触过的，所以，回顾本单元中reading里含虚拟语气的句子，先让学生有针对性地自主学习，自然地过度到对本单元的语法学习。
Step2 Making sentences
Ask the students to try their best to make sentences using the subjunctive mood.
分析：学生通过用Unit1所学的虚拟语气造句，充分展开想象力。学生们造的句子虽然简单，但非常生动、有趣：If I were a chicken， … / If I were fish， …/ If we had enough money， …/If she were a chairman， …这样可以使他们在轻松愉快的气氛中对所学知识的复习，在自主学习的基础上，通过合作、交流来完善、丰富学习经验、体会，提高参与率、积极性，也是对本节课的语法学习做了铺垫。
Step3 Grammar learning
Get the students to form group of 6. Ask them to study the following sentences and try to summarize the structure and usages of the subjunctive mood.

1.The subjunctive mood in the past tense：

（1）If I had got up earlier， I couldn’t he been late forschool.
（2）If I had been more careful， I could he done better .
（3）If I had been in the mood， I would he gone shopping.
2.The subjunctive mood in the future tense.
（1）从句谓语用过去式：
If your teacher knew it， she would be angry.
If it rained tomorrow， going hiking would be putting off.
（2）从句谓语用should+动
