四、教学步骤
Step 1 Leading-in
1. Greeting
T: Hello, everyone. Before the lesson, I want to ask you some questions.
T: How was your winter vacation?
S1: It was great.
T: What did you do in the winter vacation?
S2: I went to Sanya with my family.
T: Did you play sports? What sports did you do?
S3: Yes, I played basketball and badminton in the winter vacation.
T: Do you like playing sports?
S4: Yes, I do.
T: Today, we’ll read a passage about sports.
(Write “Unit 1 What’s the matter? Section B 2a-2e” on the blackboard.)
2. New vocabulary and new chunks learning
T: First, read the new words and phrases of this lesson.
T: Good job.
T: Look at these new chunks, match them with its Chinese meaning on the paper.
New chunks: Match the phrases with the Chinese meaning.
( )fall on sb. A.切除
( )be caught B.失血过多
( )be in a very dangerous situation C.自我包扎
( )get out of a difficult situation D.被卡住而不得动弹
( )lose too much blood E.(岩石)落向;砸向某人 ( )bandage oneself F.继续去登山
( )cut off half the right arm G.从困难的境地中摆脱出来
( )keep on climbing mountains H.处于十分危险的境地中
【设计意图】由于本课词汇量大,需要通过反复多次的朗读,帮助学生快速记忆,且要增加与之匹配的练习,进一步扫清阅读障碍,让学生充分理解文章内容。
Step Two Pre-reading
T: When we play sports, we may meet some accidents, such as, falling down, getting sunburned and so on.
T: Do you like playing soccer? What accidents may happen when people play soccer?
S1: Yes, I do. Maybe we will fall down, hurt our legs or get hit on the head.
T: Did you swim this winter vacation? What accidents may happen when people swim?
S2: No, I can’t swim. Maybe we will get sunburned or hurt our backs.
T: What are they doing? Is it safe or dangerous if you climb Beishan? Is it safe or dangerous if you climb Mount Qomolangma? What accidents may happen when people climb the mountains?
S3: They are climbing the mountains. I think it is more dangerous if we climb Mount Qomolangma. Maybe we will get sunburned or have problems breathing.
T: What sports will we read about? Please look at the picture. Read the title together.
T: What’s the reading passage about according to the picture and the title?
S: I think it’s a reading passage about a mountain climber, he is taking a risk.
【設计意图】在正式阅读文章之前,根据书上2a的问题让学生根据图片提前了解一些运动中可能会发生的意外伤害,也让学生学会意外伤害的表达方法。通过提前铺垫,再根据文章所给图片和标题对文章进行猜测,激发学生进一步阅读了解更多内容的想法。
Step Three While-reading
1. Fast reading
T:Open your book, turn to page 6. Only read the first sentence of each paragraph, then match the paragraph with its main idea on the paper.
Paragraph 1 Aron Ralston wrote a book to share hisexperience.
Paragraph 2 Aron Ralston lost his arm in a dangerous situation in 2003.
Paragraph 3 We should learn from his spirit.
Paragraph 4 Aron Ralston loves mountain climbing,although it’s dangerous.
T: Read the whole passage quickly, then finish 2c on the book, circle True, False or Don’t Know. If the statement is False or Don’t know, find out the reason.
【设计意图】快速浏览文章4个段落的首句,通过每段第一句话匹配段落大意,此任务设置在文章阅读的第一环节,了解每段的中心大意,帮助学生快速了解文章的基本内容,再通过几个简单的判断对错问题,为下一步细读文章奠定基础。
2. Careful reading Paragraph 1:
T: Why did the mountain climber lose his arm?What’s the name of the climber? Where and when did the accident happen? Read paragraph 1.
T: The accident happened in Utah, it’s a state in the United States. There are many mountains in Utah, so it’s a wonderful place for mountain climbers and hikers.
Paragraph 2:
T: What happened to Aron? There is a movie called “127 Hours”, it tells the experience Aron had. Let’s enjoy a small part of it.
T: It’s a serious accident, read paragraph 2 and then fill in the blanks about these 3 questions on the paper.
1. What happened to Aron?
2. How did Aron solve his problem?
3. What’s the result?
T: After reading paragraph 1 and paragraph 2, we have known the details of the accident. We knew what happened to Aron. Using the mind map above, you can retell the story to others.
Paragraph 3:
T: Aron saved himself, what did he do after that? Read paragraph 3 and answer the questions on the paper.
Answer the following questions after reading paragraph 3 carefully.
1. After Aron lost his arm, what book did he write?
2. What does Aron Ralston tell people in this book?
3. Did he give up after this experience?
Paragraph 4:
T: Do you think Aron is great? Why can he save himself? I think it’s his spirit. Read paragraph 4 and then discuss what Aron’s spirit is.
1. be brave
Aron’s spirit: 2. make a right decision
3. never give up.
【設计意图】细读文章各段,并设置相应的问题,帮助学生理解各段的细节问题,这样分段落进行阅读教学,在一定程度上又降低了文章的难度,易于学生理解。
Read the whole passage carefully again
(Finish 2e and show them the reading strategy: Finding the Order of Events.)
Reading strategy: Finding the Order of Events. Writers describe events in a certain order. Finding the order of the events will help you understand what you are reading .
【设计意图】本篇阅读的重点是学习利用事件的发展顺序来辅助理解所阅读的材料,让学生对这一阅读策略有更进一步的了解。通过练习,学生会结合自己的理解牢固地掌握这一策略,为日后阅读能力的进一步提高打下基础。
Step Four Post-reading
Language points
1. On that day, Aron’s arm was caught under a 360-kilo rock that fell on him when he was climbing by himself in the mountains. ① be caught 被卡住而不得动弹。

【设计意图】语言点的讲解虽然不是阅读课的重点,但是有些知识点对篇章的理解起到至关重要的作用,让学生不仅知道这些知识点在本篇文章中的意义,更要在理解单词词组意思的同时学会使用它们。
Step Five Emotion teaching
T:Do you remember Aron’s spirit? Think about it before you do everything.

五、教学评析
阅读教学设计应该是基于阅读教学内容,以培养学生的语言能力为宗旨,以具体的课堂任务为载体,以完成相应任务为动力,基于文本信息内容,把语言知识和学习技能融为一体。
为了调动学生已有的知识,为输入新的知识和技能做准备。孙老师在pre-reading(读前)做了三个活动:一是通过语块(chunks)集中学习文章中的重点短语,让学生学习不同运动伤害的表述方法,拓展学生的词汇量,为后续的阅读做好准备。另外,语块的学习也可以帮助学生扫除阅读文本中词语理解的障碍,确保学生对文本的深层次理解。二是通过一组动画图片,谈论运动中可能会出现的一些伤害,激活学生思维,使学生对即将阅读的材料有所准备。三是让学生根据图片和标题预测课文的主要内容。这种一环扣一环的导入自然、流畅,能够快速激发学生阅读的兴趣。
孙老师在While-reading(读中)阶段采用“整体阅读—分段阅读—整体再读”的教学方法,引领学生反复阅读文章,理解文章的大意。整体阅读中Match each paragraph with the main idea部分用遮盖方式让学生快速阅读文章显露的句子(每段首句),学生很容易就学会了这种阅读方法。用细读的策略阅读文本,寻找细节信息,完成2c判断正误的练习。核对答案时,孙老师要求学生把错误的句子改正过来,有效地检测了学生阅读理解的真实情况。
分段阅读中孙老师没有按照常规教学平均分配时间,而是一、三段简单处理,二、四段细致剖析。编者的目的是通过本文让学生学习按照顺序描写事件,第二段恰好给出意外事件的全过程,第四段是告诉学生要学习Aron的精神:当面对生死两难时,勇敢地做出正确决定,珍惜生命。这两段是本节课的重点和难点,也是下一节写作课的基础。如果平均分配教学时间,势必会冲淡本节课的教学重点(学会按照顺序梳理意外事故发生的过程)和教学难点(掌握意外事故的写作框架)。孙老师对文本解读得非常到位,有明确的与作者对话和与文本对话的思路。在梳理Aron发生意外事故时,孙老师先让学生观看电影《127 Hours》的片段,然后用Who、When、Where、What、How and Why六个问题,形成问题链,给出文章的整体框架,让学生带着问题去理解文章,不仅有助于提取文本信息,了解文章表层意思,品味文章深层含义,还可以形成自我的语言图式。
在处理文本的细节信息时,孙老师把文中“free”“Between a Rock and a Hard Place”和三个较为复杂且含有从句或被动语态的句子呈现出来,让学生在语境中细细品味词语和句子的含义,并试着翻译成汉语,而不是讲解复杂的语法结构,降低了文本难度,帮助学生较好地理解文本的真实意义。
孙老师在第四段用小组讨论的方式总结提炼出What’s Aron’s spirit?的答案,在“生死两难”时,每个人都应学会“勇敢面对、做出正确抉择、对自己的生命负责”。这个问题旨在提升学生的思维品质,即学生首先要观察语言和文化的各种现象,根据所获得的多种信息,通过比较、识别各种信息的异同,客观分析各种信息之间的关联和差异,同时归纳共同要素,提出自己的看法。这种教学方法有利于让学生做出准确判断,形成良好的批判性思维。
整体再读:孙老师引领学生完成文本2e,再次审视文本的框架结构,这是学生在围绕主题与文本进行对话的过程中,通过不断阅读、思考所形成的新的知识结构以及搭建的语言支架,是学生以自主学习的方式实现的语言输入,进而内化为学生自己的语言图式,顺利复述课文,实现语言输出。孙老师引导学生完成基于语篇表层信息的分析和判断任务,实现对文本的深入学习,提升学生的思维品质。
孙老师在读后应处理文中语言知识点,帮助学生积累语言知识,因为阅读教学也是学生积累语言知识的重要途径。另外,孙老师还应多关注有阅读障碍学生的课堂状态,使这部分学生跟上学习进度,学有所获。
孙老师设计的读后活动类型单一,读后活动作为阅读课中一个拓展和延伸的环节,是信息输出与反馈的重要过程,是对阅读内容的深化和巩固。孙老师若能够将阅读与听、说、写融为一体,将语言学习与真实交际融为一体,就会更加有效地提升学生的综合语言运用能力。
总之,孙老师通过读中的语言输入以及信息提取、加工、整理的过程,强化了新知识的构建与内化,整合了语言知识和技能训练,实现了“三有”。 一是通过把所学的知识条件化,即补充背景知识,让学生知道这一知识“从何而来”,让教材内容变得有温度,有情感,以实现教学内容的“有趣”。 二是通过把所学的知识情境化,即介入真实情境,让学生知道、体会教材中学的知识“到哪里去”,能解决真实世界中的问题,以实现教学内容的“有用”。三是通过把所学的知识结构化(如学生掌握了本课描述意外事件的记叙文的六要素),以帮助学生理解、记忆和迁移,实现教学内容的“有意义”。美国著名的教育心理学家、学科结构课程专家布鲁纳说:“越有结构的知识,越接近学科本质;结构化的知识有助于记忆,有助于迁移。”
