Unit 2 How often do you exercise? 教案
单元教材分析：本单元的中心话题是谈论休闲时所进行的活动，本节是本单元的第一节，通过谈论周末进行某项活动的频率，初步学会运用频率副词和目标句型来进行与同伴对话，由于本节的内容与学生的生活息息相关，语言实践性较强，很容易开展话题交流。
本单元应该用“任务型教学模式”来教学。本单元共分Section and Section B两部分，在每部分中，都有一个任务链，在每个任务链中，都有四个任务，而在每个具体的任务中，有分若干个子任务。它们是关联的，是一个有机的整体，教师在教学时，不可鼓励、分割，要明确其服务关系、逻辑关系、先后顺序的内在关系。驾驶可以知道学生妄称任务，让学生自己动手，自己研究，自己发现，自己总结。从而获得响应的语言知识和学习经验。教师做好课堂活动的合理安排。
二、学生情况分析
学生初一已学过一般现在时，并且学习现在进行时已学了许多关于活动的短语，他们已经有了描述活动的能力，因此，本单元学习时注意频率副词或短语的位置即可。只要积极参与教学任务中去，和教师、同伴进行互动、合作交流定能学好这节内容。
三、教学目标：
（一）语言目标
What do you usually do on weekend? I usually play soccer.
How often do you shop?   I shop once a month.
What do ….?  How often…?引导的特殊疑问句、频度副词。
（二）能力目标
听：能听懂谈论生活习惯和学习习惯的对话材料。
说：能运用What do ….?  How often…?句型及频度副词或短语来谈论生活习惯和学习习惯。
读：能读懂关于介绍学生生活、学习习惯的文章，。
写：能运用目标语言写关于多常学习或娱乐的短文。
（三）情感目标
1.通过What du you usually do on weekends ? 这个话题的讨论，从而培养学生学会与人沟通，善于交际、关心别人、融入社会的能力品质。
2、通过相互的调查与讨论，让他们自己得出什么样的英语学习习惯，才是最好的学习讨论方法：什么样的生活习惯，才是最健康的。输送健康概念， 从小就培养学生科学健康的世界观和积极进去的人生观。
3.了解外国中学生周末或休闲时间喜欢做的事情。
过程与方法：看图识词 、 听力配对 、 情景交际 、 综合演绎 、 读表解词 、 相互协作
（四）重 难 点：
重点：
1、以”What do …”句型为引导的日常活动：reading , watch TV , go to the movies , shop , exercise , sleep , drink milk , eat vegetables等。
2、以 “How often…”句型为引导的话题及词汇：always , usually, often , sometimes ,hardly ever , never , three times a week 等。
难点：概率词(all , most ,some , none等)与频率副词(always , usually , often , sometimes , hardly ever , never 等 )的区别

教师集中指导：

2.On weekends在周末（Saturday和 Sunday）
Weekdays指工作日，一般指星期一至星期五即（from Monday to Friday）
3.How often 多久一次，多长时间一次，是用来提问频率的短语。
How many times表示“多少次”，其答语为：once、twice、three times等。
Eg：--How many times do you watch TV every week?
Three times.
5.Twice a week 一周两次
英语中“次数”的表示方式：
Once 一次 twice 两次；
三次以上，都是用“基数词+ times”来表示。
表示次数要注意，time后面加s；
Three times 是三次，twelve times12次；
两次特殊记，once and twice。

教学反思：
现在的新教材词汇量大,单词长,生僻词较多,自然也就增加了教学的难度，但我们又必须让学生掌握，否则难以适应新教材的要求。能够引起学生学习兴趣的方法就是最好的方法．实践证明，拼图法，数字游戏，单词接龙游戏，小歌诀，顺口溜等传统教学方法并不过时，再辅以现代化的教学手段，借助图片，幻灯片，动漫等手段，真正达到重情景，重趣味，重运用，使单词具有语言的意义，使其在特定的语境中被引出，这样既便于学生理解，印象也深刻，从而达到学以致用的效果。
