Unit 4Global warming单元要览本单元的中心话题是人类当今面临的环境问题，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。
Period 1Warming Up，Pre－reading，Reading and Comprehending整体设计教学内容分析This is the first teaching period of this unit.The central part of this period is the reading passage with the title 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 greenhouse 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 about(发生；造成)，random(胡乱的；任意的)，phenomenon(现象)，subscribe(同意；捐赠；订阅；签署文件)，subscribe

on(继续)，glance(看一下；扫视)，steady(平稳的；持续的)，steadily(平稳地，持续地)2．To learn about some facts and views about global warming.3．To learn how the information is organized.4．To develop the students' reading ability by skimming and scanning the passage.5．To develop the students' speaking ability by talking about global warming.Process and methods1．While doing Warming Up the teacher can lead in the topic of this unit by showing students some pictures or videos about sources of energy，making the students recall their own knowledge about energy.2．During Pre－reading the teacher can go around the classroom and discuss the questions with several students.This discussion should be student－centered and lead them to the topic of global warming.The teacher should also ask the students to look at the graphs in the reading passage and try to find out the general idea of the text.3．While doing Reading and Comprehending，the teacher may first ask the students to read the text quickly to get the general idea of each paragraph.After reading the passage，students are encouraged to answer some questions and discuss the text structure.4．To consolidate the contents of the reading passage，the students should be required to retell the text in their own words at the end of the class.Emotion，attitude and value1．To make students realize the harm of global warming and the importance of environmental protection.2．To develop students' sense of cooperative learning.教学重、难点1．To enable the students to learn about global warming and to develop their reading ability.2．To enable the students to talk about what we should do to prevent global warming.教学过程1Warming up1．Warming up by reading and talking：Read through the exercise with the class.Put students in groups of four to talk about what we use energy for，what are the sources of these energy and whether the sources are renewable or non －renewable.Suggested answer：The six photos are：windmills；a coal power station；an oil refinery；a nuclear power plant；solar panels；a hydro－electric dam.2．Warming up by discussion：Let the students have a discussion and collect suggestions from students and write them under the appropriate heading.2Pre－reading1．Show a picture of a greenhouse to students and ask them what a greenhouse is made of and what 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.)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 magazine?________________________________________________________________________(3)What are the names of the three scientists mentioned in the article？Do they agree with one another?________________________________________________________________________ Suggested answers：(1)Global warming/the warming of the earth.(2)Sophie Armstrong，Earth Care.(3)Dr Janice Foster，Charles Keeling，George Hambley.They don't agree with each other.2．Detailed reading(1)Read the passage carefully and judge whether the statements are true(T) or false(F)．①Janice Foster believes that global warming is caused by the burning fossil fuels.()②Natural gas is a greenhouse gas.()③Carbon dioxide is a byproduct of burning fossil fuels.()④People accept Charles Keeling's data because he took accurate measurements.()⑤Flooding could be one of the effects of future global warming.()⑥George Hambley believes scientists are just guessing about the effects of global warming.()⑦George Hambley is worried about the effects of carbon dioxide on plant growth.()⑧It is clear what the effects of global warming will be.()(Suggested answers：TFTTTTFF)3．Structure analyzingAsk students to read the text carefully and try to find out how many parts they can divide theSuggested answer：4Language studyDealing with any language problem if any(words or sentences students might not understand)to help the students to have a better understanding of the text.5Listening，reading aloud and underliningAsk students to read the passage aloud to the tape and let them pay attention to the pronunciation of each word and the pauses within each sentence.Tell them to pick out all the useful expressions or collocations from the passage while reading and copy them to the notebook after class as homework.Collocations：come about，There is no doubt that...，subscribe to，due to，greenhouse effect，quantities of，tend to，be trapped in，go up，result in，on the one hand...on the other hand，be opposed to，build up，keep on.6RetellingAsk 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.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.8Reflection after teaching________________________________________________________________________。

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.。

and expressions.Step 2Warming upAsk the students to compare the two sentences below.The second sentence is from the reading passage.Translate them into Chinese and then discuss any difference in meaning and form.Ask the students to explain why “it” is used in the second sentence.Human activity has caused this global warming.It_is human activity_that has caused this global warming.Tell the students there are two more sentences in the text in which “it”is used for emphasis.Find them and then write them down.________________________________________________________________________ ________________________________________________________________________Suggested answers：1．It_was a scientist called Charles Keeling，who made accurate measurements of the amount of carbon dioxide in the atmosphere from 1957 to 1997.2．...it_is the burning of more and more fossil fuels that has resulted in this increase in carbon dioxide.Step 3Grammar learningAsk the students to study the following sentences and try to summarize the structure of the emphasized sentences.Step 4Summing upTry to help the students draw the following conclusions.1．The main structure of the emphasized sentences is “It is/was...that/who...”．2．The emphasized sentences can be used to emphasize the subject，object and adverbial(including adverbial of time and adverbial of place)．3．When we want to emphasize the subject，object and adverbial，we only need to put these parts between “it is/was” and “that/who”，the rest part shouldn't be changed.4．When the emphasized part is a person we can use both the structure “It is/was...that...” and the structure “It is/was...who...”．When the emphasized part is not a person we can only use the structure “It is/was...that...”．Step 5Grammar practiceAsk students to do the following exercises：1．Change the following sentences into emphasized sentences.(To emphasize the underlined parts.)(1)Peter lent us the money.(2)They want money.(3)All this happened on_Monday.(4)I didn't hear from her until_last_summer.(5)Why does everyone think I am narrow－minded?Suggested answers：(1)It was Peter who lent us the money.(2)It is money that they want.(3)It was on Monday that all this happened.(4)It was not until last summer that I heard from her.(5)Why is it that everyone thinks I am narrow－minded?The last two may be a little difficult for the students.Help them to get the correct answer.2．Do Exercise 2 in Discovering useful structures on Page 29.3．Do the exercises in Using Structures on Page 64.First ask students to do the exercises individually，and then let them discuss and check their answers with their partners，and finally give them correct answers and deal with any problems they might meet.Step 6Getting more about the grammarShow the following sentences to the students and ask them to find what the similarity of these sentences is.Suggested answers：In these three sentences，the underlined parts are all clauses—a subject clause and twoadverbial clauses.That is to say，the emphasized sentence can not only be used to emphasize subject，object and adverbial，but also be used to emphasize subject clauses and adverbial clauses.Pay special attention to the third sentence，in which “not” and “until” must be put together.Then show the following two sentences to students and ask them to translate them into Chinese.Pay attention to the sentence pattern.Suggested answers：(1)美国宇航员是于1969年成功登陆月球的吗？(2)究竟是谁在路上放了这么多大石头？The general question sentences and the wh－question sentences of the emphasized sentences should follow the following formulas：Is/Was it＋被强调部分＋that＋其他部分Wh－疑问词＋is/was it that＋其他部分Step 7Task－based learningAsk students to choose a topic they like(eg.global warming，wildlife，protection，music，film，etc)．Work in groups and try to tell the information they know about the topic using emphatic “it”．EXAMPLES：It was during the 20th century that the temperature of the earth went up about one degree Fahrenheit.It was Charles Keeling who made accurate measurements of the amount of carbon dioxide in the atmosphere.Step 8Closing down by a quizShow students the following on the screen or give out test papers to them and then
