of “The Earth Is Becoming Warmer—But Does It Matter?” talking about the global issue which has a great effect on human beings' life.Warming Up gives six pictures to help students list the sources of energy they can think of in our daily life.Then they will be led to discuss which energy source is “renewable” and which is “non-renewable”.This part is designed to help the students to recall their background knowledge about energy and prepares students for the whole unit.Pre-reading provides a picture of a greenhouse and then tells us what a greenhouse is and what “greenhouse gases” are.The students will be led to discuss what they think greenh ouse gases do,leading to the topic of the reading passage.Reading is a passage from an environmental magazine for young people.It puts forward the possible effect of increased carbon dioxide in the atmosphere and different points of view about it.It also analyzes the causes of the earth's increased temperature.It poses questions and encourages students to think about the issues.There are two graphs in it that tell us the “temperature difference from long-term average,1860-2000”and “carbon dioxide content in the atmosphere,1957-1997”.Characters in the passage—Dr Janice Foster,George Hambley and Charles Keeling are all real persons and their views reflect the views of some scientists today.Comprehending consists of three written or oral exercises for the students to do so as to help the students to get a better understanding of the text,that is to say,to help the teacher to check how much the students have understood the text.三维目标设计Knowledge and skills1.To know the meanings of the following new words and phrases:consume(消费;消耗;耗尽),come

greenhouse is made of andwhat its purpose is.Suggested answer:It's made of glass and plants can grow in it when it's cold outside.Ask the students how it works.Suggested answer:The glass traps the heat from the sun,making the air warm so that plants grow better.2.Ask students what they think “greenhouse gases” are and what they think greenhouse gases do.Look at the picture above and explain it to their partners.Suggested answer:Greenhouse gases perform the same function as the glass in a glasshouse:they trap the heat of the sun and keep the air surrounding the earth warm.This is called the greenhouse effect.)Step 3Reading and comprehending1.Fast readingAsk students to read the passage quickly so as to get the key words and general idea of each paragraph and answer the following questions:(1)What is the main topic of the article?________________________________________________________________________(2)Who wrote the magazine article?What is the name of the

students to talk about global warming in their own words.Give them some key words and expressions on the blackboard.Then let them try to retell the passage.Step 7Homework1.Learn the useful new words and expressions in this part by heart.2.Try to find some data about global warming on the Internet,and show your class in the next period and talk about them.Step 8Reflection after teaching________________________________________________________________________ ________________________________________________________________________教学参考About Global Warming(关于全球变暖)Global warming is the increase in the average temperature of Earth's near-surface air and oceans since the mid-20th century and its projected continuation.Global surface temperature increased 0.74±0.18℃(1.33±0.32)between the start and the end of the 20th century.The Intergovernmental Panel on Climate Change(IPCC)concludes that most of the observed temperature increase since the middle of the 20th century was very likely caused by increasing concentrations of greenhouse gases resulting from human activity such as fossil fuel burning and deforestation.The IPCC also concludes that variations in natural phenomena such as solar radiation and volcanic eruptions had a small cooling effect after 1950.These basic conclusions have been endorsed by more than 40 scientific societies and academies of science,including all of the national academies of science of the major industrialized countries.Climate model projections summarized in the latest IPCC report indicate that the global surface temperature is likely to rise a further 1.1 to 6.4℃(2.0 to 11.5)during the 21st century.The uncertainty in this estimate arises from the use of models with differing sensitivity to greenhouse gas concentrations and the use of differing estimates of future greenhouse gas emissions.Most studies focus on the period up to the year 2100.However,warming is expected to continue beyond 2100 even if emissions stop,because of the large heat capacity of the oceans and the long lifetime of carbon dioxide in the atmosphere.An increase in global temperature will cause sea levels to rise and will change the amount and pattern of precipitation,probably including expansion of subtropical deserts.Warming is expected to be strongest in the Arctic and would be associated with continuing retreat of glaciers,permafrost and sea ice.Other likely effects include changes in the frequency and intensity of extreme weather events,species extinctions,and changes in agricultural yields.Warming and related changes will vary from region to region around the globe,though the nature of these regional variations is uncertain.Political and public debate continues regarding global warming,and what actions(if any)to take in response.The available options are mitigation to reduce further emissions;adaptation to reduce the damage caused by warming;and,more speculatively,geoengineering(地球工程)to reverse global warming.Most national governments have signed and ratified the Kyoto Protocolaimed at reducing greenhouse gas emissions.。

人教版选修六Unit4《Globalwarming》word教案1
Teaching Plan for Unit 4 Global Warming (1st period)设计思路:教材分析:本课文取自于人教版新教材选修6 Unit 4,文章篇幅较长,题材属于科普类文章。
科普类文章内容较为枯燥,术语、生僻词较多,学生读起来较有困难。
好在文章话题——全球变暖的问题已为公众熟知,学生对此话题并不陌生,这一点有利于教学。
学情分析:学生是外国语学校学生,语言基础和能力水平较高,这对教学活动的展开很有帮助;但是授课者从未接触过这些学生,对他们的实际情况几乎一无所知,且上海和江西同级别的重点学校的学生水平并不一致,这给授课者在预估学生能力方面产生较大的障碍,给备课带来极大的困难。
另外,本节课因特殊原因只有35分钟,这是本堂课最难解决的问题。
授课者不得不考虑既要将文本作适当的阅读处理又要有适当的拓展,以及保证课堂的完整性的问题。
上课框架:本堂课是这篇课文的第一课时,以学生掌握文章的主旨和具体内容为主要目标。
文章标题“The earth is getting warmer but does it matter?”非常清楚地告诉了我们文章将阐述地球在不断变暖的事实,并提出疑问这究竟有没有关系?因此,本课大体分两部分进行:第一部分处理地球正在变暖的原因和事实依据,第二部分则带领学生阅读“这是否有关系”,并引发自己的思考。
因此,我设计了6个任务来完成本堂课的阅读教学。
其中五个任务以文本为基础,通过带读、自读、互相读的方式,学生利用predicting、scanning、skipping等阅读技巧来完成文本阅读,了解主旨,熟悉文章内容,抓取相关信息。
最后一个活动为讨论,使学生明白全球变暖问题日趋严重,我们还是要有应对措施,并加强环保意识。
Teaching materials:Textbook---Student’s Book 6, New Senior English for China, People’s Education Press Teaching Aids: a blackboard, a multimedia kitObjectives:I.Of Knowledge:Students will know basic scientific facts concerning global warming, scientist s’differentattitudes towards it and the writer’s opinion as well.II.Of AbilityA.Students will continue to develop their predicting skill to guess the main idea of the articleand get prepared for the reading.B.Students will practice the scanning skill to get the specific information.C.Students will learn to think critically about the problems the writer has raised.III.Of EmotionA.Students will learn we should conserve energy and protect the earth.B.Students will want to get involved in the classroom activities when doing the tasks.Procedures:I.Before ReadingLead-inA graph which shows the changes of the average temperatures of Jiangxi Province from 1959 to 2006. What can you tell from the graph? (Students’ answer may vary.)This leads to our topic today---Global warming.1. Predicting:1)What can you infer from the title?2)What are the two graphs about?II. While Reading(To make sure we are always on the same page, please mark each paragraph by writing Para. 1, Para. 2…in front of each paragraph. How many paragraphs do we have?)2. Scanning1)Look for people’s names. Circle them with a red pen.①Who wrote the magazine article?②What are the names of the three scientists mentioned in the article?2)Para. 1 & 2①What has caused global warming? (vocabulary teaching involved)②Which sentence tells us what the writer will talk about in the article?3.Reading: Para. 3, 4&5How has this come about?Further questions:1)Can you give the three examples of the fossil fuels?2)Who gave us scientific evidence that the amount of carbon dioxide has been increasing?3)Some gases can trap heat from the sun. What do scientists call this phenomenon?What would happen if there were no greenhouse effect? What would happen if there were too many greenhouse gases?4)How high will the temperature increase go according to Janice Foster?4.Reading: Does it matter? Pair Work (Para. 6)The students sitting on my left hand side will read about Janice Foster while the others will read about George Hambley. Then fill in the blanks in the table concerning your reading part. Exchange information with your desk mate so that he/she can fill in the other half.5.

Warming(关于全球变暖)Global warming is the increase in the average temperature of Earth's near-surface air and oceans since the mid-20th century and its projected continuation.Global surface temperature increased 0.74±0.18℃()between the start and the end of the 20th century.The Intergovernmental Panel on Climate Change(IPCC)concludes that most of the observed temperature increase since the middle of the 20th century was very likely caused by increasing concentrations of greenhouse gases resulting from human activity such as fossil fuel burning and deforestation.The IPCC also concludes that variations in natural phenomena such as solar radiation and volcanic eruptions had a small cooling effect after 1950.These basic conclusions have been endorsed by more than 40 scientific societies and academies of science,including all of the national academies of science of the major industrialized countries.Climate model projections summarized in the latest IPCC report indicate that the global surface temperature is likely to rise a further 1.1 to 6.4℃(2.0 to )during the 21st century.The uncertainty in this estimate arises from the use of models with differing sensitivity to greenhouse gas concentrations and the use of differing estimates of future greenhouse gas emissions.Most studies focus on the period up to the year 2100.However,warming is expected to continue beyond 2100 even if emissions stop,because of the large heat capacity of the oceans and the long lifetime of carbon dioxide in the atmosphere.An increase in global temperature will cause sea levels to rise and will change the amount and pattern of precipitation,probably including expansion of subtropical deserts.Warming is expected to be strongest in the Arctic and would be associated with continuing retreat of glaciers,permafrost and sea ice.Other likely effects include changes in the frequency and intensity of extreme weather events,species extinctions,and changes in agricultural yields.Warming and related changes will vary from region to region around the globe,though the nature of these regional variations is uncertain.Political and public debate continues regarding global warming,and what actions(if any)to take in response.The available options are mitigation to reduce further emissions;adaptation to reduce the damage caused by warming;and,more speculatively,geoengineering(地球工程)to reverse global warming.Most national governments have signed and ratified the Kyoto Protocolaimed at reducing greenhouse gas emissions.。
Unit 4 Global Warming 教学设计1-公开课-优质课(人教选修6精品)
Unit 4 Global warming教学案1教材分析Ⅰ.教学内容分析本单元的中心话题是人类当今面对的环境问题,主要探讨了“全球变暖”和“节约能源”等方面的问题。
由于人类过多使用不可再生能源,大气中二氧化碳的含量逐年增加,导致全球气温上升。
通过学习本单元,让学生了解能源分为“不可再生能源”和“可再生能源”,帮助学生树立“节约能源、保护环境”的主人翁意识。
语言知识和语言技能主要围绕“全球变暖”和“节约能源”这一主题设计的。
“热身”(Warming up) 部分要求学生列举家中、学校或其他地方使用能源的物体,指出这些能源的来源,并尽可能多地列举不同的能源。
能源可分为两类:一类是可再利用能源;另一类是一次性能源。
把前面列举的能源按能否再利用这一标准进行分类。
本部分提供了六幅图片,教师可以从识图开始组织教学。
还可以让学生搜集一些其他相关图片。
这六幅图分别为:风力(wind power)、燃煤发电站(a coal power station)、炼油厂(an oil refinery)、原子能发电站(a nuclear power plant)、太阳能接受器(solar panels)、水坝(a hydro dam)。
“读前”(Pre-reading) 部分首先介绍什么是温室、它有什么作用,然后要求学生讨论大气中温室气体的作用。
温室是由玻璃构成的建筑,主要用于花果蔬菜的培植。
温室是由玻璃构成的建筑,主要用于花果蔬菜的培植。
温室能阻止热量散发,因而能帮助植物度过寒冷的时期。
该部分的讨论有利于学生预测课文内容和理解阅读课文中的温室气体效应。
“阅读”(Reading) 部分是一篇杂志文章,主要讲述了地球温度上升的现象和原因。
20世纪中,地球的温度上升了华氏1度。
这看上去是一个很小的数字,但相对于自然界的其他现象来说,这个增长速度是迅猛的。
这种现象是自然发生的还是人为的?这个问题引起激烈的争论。
许多科学家认为,这种变化是人类燃烧矿物燃料所致。
