专家点评(交大附中陈江丽)
亮点:
1. 本节教学设计的教材分析非常到位:分别详细论述了本单元的教学内容,本课教学的内容;本节课是本单元的第几课时,本节课在本单元起着开篇引领的作用和教师的设计思路。
非常全面,到位。
2. 学情分析具体细致,涉及到目前学生已有的基础,展现的问题和弱项。
3. 教师的任务型阅读教学法和交际式教学法和策略定位合理,科学。
不足之处:
1. 本节课的知识技能目标与教学重点中都提到重点词汇,但是在教学环节中没有体现教师是如何让学生掌握这些词汇的。
2. 阅读的层次设计不够科学。
原则上在学生skimming 的环节中,学生要掌握阅读材料的大意。
然后学生scanning寻找理解文章的细节信息;其次学生研读一些关键句子或段落,理解生词汇的意义,对长难句进行分析;最后学生再次阅读重点段落找出作者的写作手法,作者的隐含意等等,加深对阅读材料的理解。
本教学设计把文章的主题理解没有放在第一步阅读中进行。
3. 在读后环节教师设计了summary,并把它设置成短文填空的形式,降低了难度。
但此环节只是对文章的简单的总结,并没有上升到对文章深层次的理解。
建议教师在此设计一些创造性的问题,发散性思维的问题,或评价性的问题,引导学生运用所学的英语做事的能力,培养学生的综合运用英语语言的能力。

Module 4Sandstorms in Asia【美文阅读】How to Survive a SandstormSandstorms are among nature's most violent and unpredictable phenomena(现象).High winds lift sand into the air,reducing visibility(能见度) to almost nothing in a few seconds.Nearly all dust storms are capable of causing property damage,injuries,and deaths.No matter where you live,it's a good idea to know what to do if you see a wall of sand racing toward you.Here are some tips for you.Be prepared.If you are in a stormy area,carry a mask designed to remove small sand,and bring airtight goggles(密封护目镜) to protect your eyes.It's also wise to carry a supply of water in case you are tracked in a storm.Dust storms are usually acpanied by high temperatures,and you can quickly bee dehydrated (脱水的)in the dry heat and high winds.Wear or carry clothing that covers your body to protect yourself from the sandblasting,and to keep warm.Outrun(比……跑得快) the storm.If you see a sandstorm from a distance,and you are in a vehicle or have access to one,you may be able to outrun it.Some sandstorms can travel at more than 75 miles per hour,but they often travel much slower.Trying to outrun astorm,however,is not advisable if you have to put yourself at risk by traveling at high speed.If the storm is catching up with you,it's best to stop and prepare for it.Take cover and stay still.Do not attempt to move about in a storm,as you will not be able to see potential danger in your path.If you're in a house,stay inside.If you can quickly reach such a place before a sandstorm reaches you,get there as quickly as possible.Close all windows and doors,and wait out the storm.If you're in a vehicle,roll up the windows and turn off the vents that bring outside air in.If you are outside,seek out a large rock to protect yourself at least partially.Protect yourself from flying objects.Cover as much of your body as possible to protect yourself from flying sand.In addition,while the sand can hurt,a sandstorm's high winds can also carry heavier(and hence more dangerous) objects.If you find yourself no place to stay,try to stay low to the ground and protect your head with your arms, or a backpack.【诱思导学】Sandstorms have been a major disaster for many Asian countries for centuries.What should we do to reduce or stop sandstorms?【答案】Students' own answer.Period ⅠPreviewing●教学目标本课时主要是通过学生对学案所给出的内容的学习,了解本课文中所出现的词汇,初步了解课文以及相关的背景知识,对下一堂课对课文的全面理解起到一个铺垫作用。
