教学过程:
一、Pre-class
1. Greeting
2. Leading-in
学生活动:
(1)讨论活动1的问题,发表对“改变坏习惯”这个话题的看法。
1 Are bad habits easy to change? Why or why not?
2 What habits do you think are unhealthy?
3 What can you do to correct these bad habits?
(2)学生浏览活动2的指示语和选项,根据文章标题Habits for a Healthy Lifestyle预选答案,推测文章
将讨论哪些主要内容,并将预选答案排序,初步思考文章的结构。教师可引导学生关注每个选项的关键词与标题之间的联系,初步建立对篇章结构的整体印象。
(3)学生浏览策略提示框,为接下来的阅读做好准备。
活动目的:活动1是读前思考和讨论的环节。学生首先根据自己的生活经验判断
不良习惯是否容易改变,进而讨论有哪些不良习惯,最后思考可以怎样纠正这些不良习惯。这个过程能激活学生有关习惯主题的知识和经验,帮助他们形成阅读期待。从思维层次来看,活动1让学生调取生活经验,谈谈自己对不良习惯的认识,以及已知的改变习惯的做法,属于识记层次的思维活动。活动2是快速阅读环节,引导学生关注文章各个段落的主旨大意。获取段落大意是本单元的主要阅读策略。了解各段落的大意有助于学生理解文章的主要内容,厘清文章的行文脉络,提高阅读效率。从思维层次来看,活动2需要学生分析段落的信息和观点,然后进行概括和总结,属于理解层次的思维活动。
二、While-class
学生活动:归纳段落大意。学生浏览文章,逐段提炼主旨,检验并调整活动2
的答案和排序。
教师活动:(1)核对答案前,允许学生先与同伴或小组讨论。核对答案时,可以请学生具体说出各段大意的匹配依据。例如在第一段,引导学生出本段的关键句“To prevent harmful habits like these from dominating a teenager's life is essential”。教师可以简单分析,作者使用那么长的句子主语,目的就是要让这个句子引起读者注意。所以,这段的大意是Why bad teenage habits should be changed。
(2)在最后一段,引导学生发现关键句“However,there is no 'magic pill' or delete button that will help you; you have to think about your bad habits and decide on some changes”。这个句子用
However表示转折,引起读者注意,这也是突出句子的一种方式。此外,magic pill,delete button都是easy way的近义词,所以可以判断这段的大意是“No easy way to change bad habits.”。
(3)分析文章结构,明确作者写作意图。教师可根据活动2所提供的段落大意,利用课件归纳全文的脉络。例如:
Why bad teenage habits should be changed→
What a habit is→
The cycle of how habits are formed→
How to change a bad habit and create good ones→
Changing habits gradually→
No easy way to change bad habits
活动目的:将行文脉络图示化,并凸显why、what、how三个词,可帮助学生从
宏观上把握文章各部分的逻辑关联,从而理解作者的写作意图。
(4)基于图示,教师引导学生提炼篇章结构,将全文分为三个部分。
●Paragraph 1:Why bad teenage habits should be changed
●Paragraphs 2 to 5:What a habit is and how to change bad habits
●Paragraph 6:No easy way to change bad habits
教师进而可通过提问引导学生思考作者的写作意图
●Why did the writer write this text?
●Who's the intended reader?How can you tell?
参考答案:
●To explain a teenage problem and suggest possible solutions.
●The intended readers are young people,especially teenagers. The first paragraph
mainly discusses why it is easy for teenagers to form bad habits. The last
paragraph starts with "For young people …."and "you" is used to address the
reader.
(6)理解关键细节,分析写作方法。教师可结合活动3的前四个问题,让学生进行小组讨论。
How can a choice lead to a habit?Show the process in a diagram
What are the three stages of the habit cycle?Do you think the writer explains it clearly?How?
What should we do to change a bad habit?Give an example by filling in the following table.
How can a person use discipline to help change a bad habit?
(7)撰写文章摘要。教师可以引导学生回顾摘要写作的基本原则,提醒学生参考已经梳理的文章结构,尽量使用自己的话来表达。
活动目的: 活动3的问题1至问题4涉及了文本话题的四个主要方面,即习惯的形成过程、习惯循环原理、运用该原理改变不良习惯、运用该原理的注意事项。问题5是一个基于文本又超越文本的问题,询问学生是否愿意运用所学改变自身的不良习惯、养成健康的生活习惯。学生的情感态度和价值观在这个任务中得以展现。
三、After-class
教师活动:
(1)回顾总结所学文本。教师可提出以下问题供学生思考并回答:
What important message have you learnt from this text?
Will you use the habit cycle to break your bad habits?Why or why not?
(2)完成活动4第一个任务。学生小组讨论:如何运用习惯循环原理改变自己的一个坏习惯。教师可以使用之前的表格,也可以讲述一个改变坏习惯的经历,作为启发学生思考和表达的支架。教师可以边陈述边呈现下面表格的内容:
(3)完成活动4第二个任务。小组讨论其他改变坏习惯的有效方法。教师可以继续利用刚才
例子进行示范。
To help myself form the new habit,I always invite some colleagues to walk together with me. While we're walking, we chat. That makes me feel that I'm not doing it alone and the walking becomes more interesting and I'm more willing to do it. Here is my strategy.
●Find company.
●Do something I like while trying the new routine.
四、Summary
总结课上所学。
作业布置:阅读两篇有关改变坏习惯的网络求助帖子,选择其中一个进行回复,给出具体的建议。通过写作任务运用学到的知识。
healthylifestyle帖子1:I have been suffering from the bad habit of overeating for decades. Every time I feel upset,I eat a lot. Overeating is the most effective way for me to relieve stress temporarily. It is ironic that I eat even more when I feel anxious about gaining weight.
I am overweight and frequently have a stomachache. What shall I do?I really want to get rid of this terrible habit.
帖子2:My friends call me a night owl. I often stay up late and go to bed after When I am actually in bed,I still can't help playing with my cellphone for one hour or more. In other words,I fall asleep later than I feel dizzy from time to time. I find it hard to work efficiently at daytime. Sleeping late even makes my skin look bad.
I know it is an unhealthy habit but I don't know what to do.
