Unit 2 How often do you exercise
Section B 3a-Self Check 教学设计
教材分析：
人教版八年级上Unit 2 Section B 3a-Self Check Page15，本单元的教学内容是“How often do you exercise ”为话题展开教学活动。首先让学生学会恰当地使用频率副词及短语(always, usually, often, sometimes, hardly ever, never) 再学会描述自己或他人的生活方式。通过复习已学习过的动词及短语：(shop, exercise, read, go to the movies, watch TV, ,read books ,eat hamburgers, drink juice )，使学生积极参与，主动合作，让学生在完成任务的过程中，使用英语获取信息，用英语进行交流，从而培养学生运用英语的能力。本单元的Section A部分，已初步认识和使用了频率副词，为进一步使用频率副词及动词短语做语言知识上的准备。本课时主要在此基础上培养学生对语言知识点的综合运用能力，让学生学会阅读、学会写作，学会调查，让学生在体验中内化语言知识，从而培养学生对频率副词以及 how often句型的使用能力。

【课时安排】：1课时
【课前准备】：
1.运用多媒体辅助教学，能使抽象的语言变得直观形象，为学生运用英语进行交际创设情景，实现师生互动，生生互动多向交流。
2.准备好录音机，制作多媒体课件及学案。
教学设计
教学过程设计
一、复习热身
1、检查本课时生词的预习情况。
（1）让个别学生朗读生词，教师及时正音。然后领读，齐读。
（2）听写生词。让学生以合作小组为单位互批互改，小组长汇报检查情况。对表现好的提出表扬,如果学生掌握情况不好，教师可以结合读音规则等方法帮助学生识记生词。
2、复习导入
（1）利用多媒体出示图片导出已学过的单词和短语。
Healthy food: milk, fruit, vegetables
Unhealthy food: junk food, coffee, cola, chocolate
eat junk food/fruit/vegetables, drink milk/coffee, play sports, how often,
every day, hardly, ever, never, two or three times a week
（2）利用上面的单词和短语通过对话形式复习下列句型。
How often do ….. How often does …
It is good/ bad for one’ health.
①Make a conversation with the students:
T: Excuse me Do you like……. S: T: How often do you….. S: T: It’s good/bad for your health.
②Then ask them to work in pairs.
(通过“复习导入”的方式复习上节课所学知识，自然过渡到本节课的内容，既为下面的3a-SelfCheck的学习做好了铺垫，也提高了学生的自信心。首先通过师生之间的交流做出示范，适当引导，然后实现生生之间互动交流。)
(3)做调查
(通过上一环节的准备与铺垫，将“4部分的调查”提前至此，既增强了学生的自信心，调动了学生学习的积极性，主动性，提高了学生学习英语的兴趣，也为下一步的写作打下基础。)
Fill in the charts(绘制三个表格，分别调查)
How often
activity
exercise
Play sports
Eat fruit
your parents and your best friend

(2)Compare and decide: Who is the healthiest person
二．阅读训练:
1.速读：让学生阅读下面的问题，然后快速阅读短文并选择正确答案。（训练学生快速阅读、捕捉主干信息的能力。）
What does Jane’s information in the chart
Her exercise. B. Her eating habits.
C. Her sleep. D. Her lifestyle.
2、细读：让学生再认真阅读短文，完成下面的表格，小组讨论后在课内通过多媒体交流展示，下表自exercise分层次逐步展开。（深入课文内容、扫除障碍、加深记忆）
Jane’s lifestyle
exercise
Eating habits Healthy food
Unhealthy food
Sleep
Conclusion Do you think she has a healthy lifestyle Why or why not Is her lifestyle the same as yours or different What are the differences
3、朗读：教师首先播放录音，让学生跟读，享受地道的英语，感悟语言。然后学生自由朗读。教师抽查学生朗读情况，及时纠正读音、语调、停顿等。这样可以训练和培养学生欣赏文章的意识和能力。
4、精读：学生再进一步阅读，找出短文中的重点句子、短语，发现疑难点，小组内讨论，学生发言解答，教师适当点拨。学生完成笔记。通过这个环节，扫除短语及语法的应用障碍，为写作做好铺垫。
If necessary,the teacher can explain the followings:
(1) stay up late e.g. She often stays up late
(2) help sb(to)do sth. e.g: Can you help me (to) study English
(3) the same as … e.g: Lucy is the same as Lily.They are twins
(4)help with e.g: Because she goes to the dentist for more than two hours a day.
三、强化巩固
1、根据上面表格内提示的信息复述短文，１至２名学生展示。（教师可适当示范或引导）
2、学生独立处理3b，将3b设计出三种难易不同的形式供层次不同的学生选做。
(1)选用给出的单词或短语完成下面的短文。
Never, always, often, usually, sometimes, hardly ever,
(2)根据给出的首字母提示写出适当的完整的单词形式，完成下面的短文。
(3)教材中的原型。
3、做针对性练习（同步学习第16页第3题）：
四、语言运用(写作训练)
Encourage the Ss to write about their own habits according to the following
questions（连词and, but, although, so等的使用会使你的文章更流畅！）
①Are you healthy or unhealthy
②How often do you exercise
③How often do you eat vegetables,fruit,or junk,food
④How often do you drink milk or coffee
⑤How many hours do you sleep every night
设计这几个小问题作为写作铺垫,让他们感觉有话可说，这样可以鼓励学生积极参与进来。）

五、总结反馈
What have we learned today Let’s make a summary.
Words: ___________________________________________________
Expressions: ___________________________________________________
How to get a healthy lifestyle ______________________________
_________________________________________________________
六、作业布置
1、背诵3a .
2、完成同步练习中的Section B．
3、复习并思考3a-4的课文内容。同学之间用How often do you exercise 对话。
板书设计

教学反思：
这是一节读写课，阅读和写作是两项，相对独立，但又是相互依赖、相辅相成的技能。叶圣陶先生曾经说过：“阅读是吸收，写作是倾吐，倾吐能否合乎于法度，显然与吸收有密切的联系。” 根据认知心理学观点，一方面，语言应用能力（写作）的提高是建立在大量的语言输入，尤其是大量的阅读基础上；另一方面，语言知识的输出能有效促进语言知识的内化。所以首先要抓好3a的阅读训练，通过设计任务，采用多种读法，排除学生写作的心理压力和障碍。对于采访调查环节，把它放在学生写作训练之前，就是先让学生感知、内化所学语言内容，培养口头交际的能力，也为写作搭好铺垫。学生阅读的过程，也就是学生模拟写作的过程。学生能通过对阅读材料的理解，揣摩作者的意图，身体力行地扮演作者角色，悟其理，师其法。通过对阅读材料的模仿来提高写作技能。通过阅读，有助于学生加深对已学单词的理解和记忆，使这些词汇在反复的接触和运用中得以巩固,为写作储备丰富的语言知识，获得大量的阅读和运用知识的机会，在此基础上进行写作，写作过程便呈现简单化，而且也富有创造性。
