Unit 2 Healthy Lifestyle教案

Readingand Thinking: Climate Change Requires World Attention

文本简析

本单元阅读文本的话题是“健康的生活方式”，旨在帮助学生认识习惯的本质及其运转原理，在此基础上，利用习惯周期，聚焦影响习惯改变的关键因素，尽早识别和改变坏习惯，从而树立积极的生活态度和健康的生活方式，提升识别问题、分析问题和解决问题的意识和能力。

本语篇类型为论说文，兼具议论文和说明文的特征。文本第一段旨在提出问题，作者阐述了坏习惯的危害，并指出青少年应学会尽早识别坏习惯并做出恰当改变。第二、三段旨在分析问题，作者阐明了习惯的内涵，并利用现代心理学知识——“习惯周期”，揭示了习惯的运转原理。第四、五段旨在解决问题，第四段阐述了习惯周期的应用价值，第五段则阐述了改变坏习惯的其他关键因素，包括时间和自律等等。第六段作者重申论说点，并呼吁年轻人认真思考并做出改变，从而建立健康快乐的生活方式。

在进行本文教学设计时，除梳理文本内容和结构外，教师应引导学生积累有关“健康的生活方式”的话题词汇，如physical and mental health, habit, appropriate, alcohol,tobacco, abuse, facilitate, examine, discipline, dominate等。学生学习语言时，应尽可能融合内容的学习及思维的培养。引导学生利用思维导图梳理语篇结构，建构对习惯这一概念及其运转原理的认识，培养其逻辑思维能力，提高学生认识问题、分析问题和解决问题的能力。

第1课时

一、教学内容

整体梳理语篇结构和文本内容，归纳坏习惯的危害，提炼习惯的关键特征，建构对习惯的认识，阐述习惯运转原理，运用“习惯周期”理论分析常见的坏习惯，思考“习惯周期”对改变坏习惯的积极作用。

二、课时目标

1. 通过自主提问，整体阅读文本、梳理语篇宏观结构、明确文本主要内容。

2. 通过归纳坏习惯的危害，树立尽早识别和改变坏习惯的意识，融入tobacco, alcohol, abuse, dominate等语言学习。

3. 提炼习惯的关键特征，包括重复性、选择性、自发性和不易改变性，正确建构习惯的概念。

4. 通过同伴互助，阐述习惯运转原理，运用“习惯周期”分析坏习惯，思考其对改变坏习惯的作用。

三、教学过程

Activity1: Talking about habits and raising questions by students themselves

本活动为实现课时目标1作铺垫。

1.Checkand talk about teenagers’ habits.

Ask studentsto check their own habits and share their opinions on the following questions.

Q1: Haveyou ever checked what habits you have? Make a list of them in one minute.

Q2: Undoubtedly,there are good habits and bad ones in our lists. Do you want to change your badhabits?

(Accordingto students’ different opinions, the teacher writes down the following questionson the blackboard: Should bad habits be changed?)

Q3: Is thereany bad habit you want to change but seemingly impossible to change?

2.Raisequestions by students themselves.

Ask studentsto brainstorm what are needed if we want to change bad habits.

Q1: Today,let’s make what seems impossible possible. To change our bad habits, in your opinion,what do we need to know?

Possibleanswers:

(1)Why arebad habits so difficult to change?

(2)How arebad habits formed?

(3)How canbad habits be changed?

(Accordingto students’ different ideas, the teacher writes the second and the third questionson the blackboard.)

【设计意图】步骤1让学生观察和罗列自身习惯，包括好习惯和坏习惯，并针对是否想要改变坏习惯，是否有想改变坏习惯却似乎改不掉的现象表达自己的观点和看法。在此过程中，教师收集学生最普遍的坏习惯，铺垫语言如abuse, alcohol, tobacco等，从而为后续阅读做好话题和语言上的准备。步骤2针对解决问题，让学生展开自主提问和思考，教师筛选出学生的自主提问，为后续语篇学习提供方向。

Activity2: Figuring out the main idea and the structure of the article

本活动为实现课时目标1。

1.Read tofind out which questions are answered and in which paragraph(s) they are answered.

Ask studentsto read the whole passage and make sure whether the following questions are discussed.If yes, relate the questions with paragraphs.

Q1: Shouldbad habits be changed?

Q2: Howare bad habits formed?

Q3: Howcan bad habits be changed?

(Possibleanswer: Paragraph1 is mainly about the first question, Paragraphs2-3 are about thesecond question while Paragraphs 4-5 are mainly about the last one.)

【设计意图】该活动学生带着问题展开整体阅读，梳理文本主要内容和框架，有助于培养学生的语篇意识。

Activity3: Figuring out whether bad habits should be changed (Paragraph 1)

本活动为实现课时目标2。

1. Readto find out whether bad habits should be changed.

Ask studentsto read Paragraph 1 carefully and underline the supporting evidence.

Q1: Shouldbad habits be changed?

“These badhabits, if left unchecked, could lead to more serious ones when they become adults.”

2. Whatcan be known from “when they become adults”?

(Possibleanswer: “in the long run” or “as time goes by”)

3. Why doesthe author give the example of “tobacco and alcohol abuse” ?

(Possibleanswer: it is to explain “more serious”, which refers to both “physical and mentalhealth problems”)

The teacherthen helps students make a conclusion.

“In a word,bad habits will cause physical and mental health problems in the long run, so theyshould be changed early. Never should teenagers let bad habits ___________theirlife.”

(Possibleanswers: influence, affect (not powerful enough) ; rule, control, dominate)

【设计意图】学生细读第一段，聚焦主要句子，通过分析和推断，提炼出坏习惯应该尽早改正的原因。在语境和观点表达中，体验不同语言的力量，从而感受dominate一词的真正涵义，体会到改变坏习惯的必要性。同时，根据学生回答情况，教师也可融入“健康与快乐”之间的辩证关系。

Activity4: Figuring out how bad habits are formed (Paragraphs 2-3)

本活动为实现课时目标3和4。

1. ReadParagraph 2 and think about the key features of a habit.

Ask studentsto underline the main characteristics of a habit based on their reading.

Q1: Whatcharacteristics does a habit have?

(Possibleanswers: repeatedly, choice, automatic, much harder to change)

2. Workin pairs, read Paragraph 3 and draw out the habit cycle of one of your shared badhabits.

3. Drawa conclusion and think further.

Q1: Is itdifficult for you to understand how habits work?

Q2: Howdoes the author make the habit cycle more accessible to readers?

(Possibleanswers: by giving the definition, by giving a diagram, by giving an example.)

【设计意图】步骤1旨在引导学生分析和概括习惯的主要特征，包括重复性、选择性、自发性和不易改变性，继而针对“不易改变”这一特征展开思考，引出习惯的运转机原理。步骤2通过同伴互助，选择之前分享过的共同需要改变的习惯，通过学习文本，学会自我审视和自我分析。在分享时，教师引导学生解决出现的理解问题，例如reward, routine出现错误的情况，从而正确运用习惯周期。步骤3教师引导学生思考作者如何让抽象的现代心理学理论变得通俗易懂。该活动有助于提升学生的逻辑思维能力，语言表达能力以及理论知识的学习能力。

Assignment

【设计意图】学生选择自己想改变的坏习惯，利用习惯周期展开分析，结合对习惯这一概念及其特征的认识，思考并举例说明习惯周期对改变坏习惯是否有积极作用。该活动旨在检测学生对本课时内容的掌握情况，同时为下一课时的学习作好铺垫与准备。

Ask students to share their writings in frontof class.

Q: Can thehabit cycle help to change bad habits? If yes, how can it help? Report your ideaswith a specific example of your own habit cycles.

【设计意图】该活动让学生针对第一课时作业发表观点并做课堂展示，一方面能检测学生对第一课时的掌握情况，另一方面借助学生习作回顾课文主要内容，同时能切入第二课时的阅读。

Activity2: Reading to find out the application of the habit cycle (Paragraph 4)

本活动为实现课时目标1。

1.Read towork out the author’s opinion on the application of the habit cycle.

Ask studentsto read Paragraph 4 and figure out what can the habit cycle be used for.

The routine.Change the routine, change the bad habits.

【设计意图】引导学生关注段落承上启下的关键句，梳理出段落内结构，从而快速提炼出习惯周期的两种应用。抓住adapt的具体指代及两个例子的共性，提炼出改变坏习惯的关键在于改变习惯周期中的惯常行为（routine），以此提升学生的语言能力和思维能力。

Activity3: Reading to figure out other key factors in changing bad habits

Q1: How can bad habits be changed?

(Possibleanswer: We should spend a period of time in changing the routine into a healthierone with strong willingness, great discipline and repeated efforts. Gradually, badhabits can be and will be changed.)

【设计意图】通过抓住习惯周期能否让习惯改变立竿见影，引导学生阅读第五段，分析、思考并概括习惯改变的其他关键因素，进一步加深对习惯及其改变的理解，提升逻辑性思维能力。聚焦学生的难点，即对“discipline”的理解，教师运用情境帮助学生理解涵义，从而提升语言能力。借助“千里之行，始于足下”，思考改变坏习惯的最根本最开始的一步，从而与单元主题建立关联，体现主题意义。最后让学生整合第四、五段内容，回答学生提出的最后一个问题——如何改变坏习惯，该活动综合了内容、语言和思维。

Activity4: Figuring out the structure and the writing purpose

本活动为实现课时目标2。

1.Read Paragraph6 and think about its main idea and the writer’s writing purpose.

Q1: If youwere the author, how would you end your article?

【设计意图】步骤1旨在预测和验证文章最后一段主要内容，梳理完整的语篇结构，步骤2旨在思考和讨论作者的写作目的。教师也可根据学生课堂反应情况融入对语篇人称多次转换的思考。

Activity4: Thinking, reflecting and sharing opinions

本活动为实现课时目标3作铺垫。
