MATTER?全球在变暖这会带来什么影响吗？,1/36,Skimming,Skim the title:,THE EARTH IS BECOMING WARMER BUT DOES IT MATTER?,What is the main topic?,The earth.B.Global warming.,C.Becoming warmer doesnt matter.,2/36,Where does this article most probably come from?,Newspaper B.Novel C.Magazine,3/36,During the 20th century the temperature of the earth,rose,about,one degree Fahrenheit.,在20世纪期间，地球温度大约升了华氏1度。,That probably does not,seem much to you or me,but it is,a rapid increase,when,compared to,other natural changes.,这个数值对你我来说很可能是无所谓，不过跟其它自然改变相比较而言，这却是一个快速增加。,So how has this,come about,and does it matter?,那么，这种温度增加是怎么产生呢？会产生什么影响呢？,Earth Care,s Sophie Armstrong,explores,these questions.,“关爱地球”组织索菲阿姆斯特朗就在探究这些问题。,compared to,与,.,比较；把,.,比作,.,come about,产生,4/36,c,ome about,c,ome about:,t,ake place;happen,表示“发,生、产生”，多指事情已经发生了，但,还不知道为何，惯用于疑问句和否定,句,例,:,When Mother woke up,she didnt,know what had,come about,.,Ill never understand how it,came about,that you were late three times a week.,5/36,Who wrote the article?,What is the name of the magazine?,Skim the first paragraph:,Sophie Armstrong,Earth Care,听录音,6/36,There is no doubt that,the earth is becoming warmer(see Graph 1)and that,it is,human activity,that,has caused this global warming,rather than,a random but natural phenomenon.,毫无疑问，地球是在变暖（见表一，略），而地球变暖正是人类活动造成而成，并非是一个无规律自然现象。,7/36,it is,human activity,that,has caused this global warming,rather than,a random,but,natural phenomenon.,a random,but,natural,修饰,phenomenon,，译为,“,随意自然现象,”，,but,起一个,语气转折作用，可不译出。,8/36,rather than,而不是,She is a career woman,rather than,a housewife.,她是职业妇女而不是家庭主妇。,rather than,在更大程度上,These are political,rather than,social matters.,与其说这些是社会问题，不如说是,政治问题。,9/36,Part,II(Para2-3),Everyone believes that global warming is caused by the activities of humans.,Janice Foster believes that she can measure the future global rise in temperature.,Greenhouse Gases are totally bad.,F,T,F,10/36,All scientists,subscribe to,the,view,that the increase in the earths temperature is,due to,the burning of,fossil fuels,like coal,natural gas and oil to produce energy.,全部科学家赞同这种观点：人们为了生产能量而燃烧化石燃料（如煤、天然气和石油等），从而引发了地球温度升高。,Some,byproducts,of this process are called,greenhouse,gases,the most important one of,which,is carbon dioxide.,这个升温过程一些副产品就叫做“温室”气体，其中作用主要就是二氧化碳。,11/36,1.Greenhouse gases refer to_.,carbon dioxide,B.the burning of fossil fuels,C.byproducts of the burning of fossil fuels,D.coal,natural gas and oil,scanning,Reading Comprehension IV,12/36,Dr Janice Foster explains:There is a natural phenomenon,that scientists call,thegreenhouse effect,.,贾尼丝福斯特博士解释说：“有一个科学家称之为温室效应自然现象。,This is,when,small amounts of,gases in the atmosphere,like carbon dioxide,methane and water vapour,trap,heat from the sun and therefore,warm,the earth.,这种现象发生在大气层中少许气体（如二氧化碳、甲烷、水蒸气等）吸收太阳热量，因而使地球变暖时候。,13/36,2.Greenhouse effect _.,A.is a natural phenomenon,B.happens when theres too much carbon dioxide,C.does great harm to human beings,D.makes life for human beings better,scanning,Reading Comprehension IV,14/36,Without the greenhouse effect,the earth would be about,thirty-three degrees Celsius,cooler than it is.假如没有这种温室效应，地球温度将比现在温度还要低33摄氏度左右。So,we need those gases.The problem begins when we add,huge quantities of,extra carbon dioxide into the atmosphere.所以，我们需要这些气体。当我们在大气层中增加了大量额外二氧化碳时，问题就来了。It means that more heat energy,tends to,be trapped in,the atmosphere causing the global temperature to,go up,.这意味着更多热量被困在大气层中，从而引发全球温度上升。”,quantities of,大量,tend to do sht,倾向做某事,be trapped in,被困住,go up,上升,15/36,1.Greenhouse effect is a natural p,_.,_ amounts of Greenhouse gases in the atmosphere.But the problem begins when we add huge q,of extra carbon dioxide to the atmosphere.Therefore,more heat energy is t,in the atmosphere causing the global temperature to _.,Fill in the blanks about the,causes,of Greenhouse effect.,henomenon,uantities,rapped,go up,Small,16/36,We know that,the levels of carbon dioxide,have increased greatly,over the last 100 to 150 years,.,我们知道，在过去100150年期间，二氧化碳含量急剧增加了。,It was,a,scientist called Charles Keeling,who,made accurate measurements of,the amount of,carbon dioxide in the atmosphere from 1957 to 1997.,有一位名叫查尔斯基林科学家曾经把19571997年期间大气层中二氧化碳含量作了准确统计。,He found that between these years the carbon dioxide in the atmosphere went up from around 315 parts to around,370 parts per million,(see Graph 2).,他发觉，在这些年里，大气层中二氧化碳含量从315/1000 000上升到370/1000 000。（见表二，略）,accurate measurements 准确统计,the amount of.,数量,17/36,18/36,3._ found out the amount of carbon,dioxide in the atmosphere from 1957 to1977.,A.Dr.Janice Foster B.Charles Keeling,C.George Hambley D.Sophie Armstrong,19/36,Para 4.,the levels of carbon dioxide have,increased greatly over the last 100 to 150 years,1.How much has increased?,The carbon dioxide in the atmosphere went up from around 315 parts to around 370 parts per million.,20/36,All scientists accept this data.,全部科学家都接收这个数据。,They also agree that,it is,the burning of,more and more,fossil fuels,that,has,resulted in,this increase in carbon dioxide.,他们还赞同下述观点，正是因为越来越多燃烧化石燃料造成了二氧化碳增加。,So how high will the temperature increase go?,那么气温会升到多高？,Dr Janice Foster says that,over the next 100 years,the amount of warming,could be,as low as,1 to 1.5 degrees Celsius,but it could be,as high as,5 degrees.,福斯特博士说，在今后1里，全球变暖量可能低到11.5摄氏度，不过也有可能高达5摄氏度。,21/36,Para 5.,How high will the temperature go?,The amount of warming could be as low as 1 to 1.5 degrees Celsius,but it could be as high as 5 degrees.,22/36,However,the,attitude,of scientists,towards,this rise is completely different.,然而，科学家们在对待升温态度上却是大不相同。On the one hand,Dr Foster thinks that the,trend,which increases the temperature by 5 degrees,would be a catastrophe.首先，福斯特博士认为气温升高5度趋势可能是一场大灾难，,She says,We cant predict the climate well enough to know what to expect,but it could be very serious.,她说：“对于未来气候，我们不可能做出准确预测，不过那时天气可能是很糟糕。”Others,who agree with her,think there may be,a rise of several metres,in the sea level,同意她观点其它科学家认为，全球变暖会造成海平面上升好几米；,or predict severe storms,floods,droughts,famines,the spread of diseases and the,disappearance,of species.,也有些人预言会出现严重风暴、洪涝、干旱、饥荒、疫病和物种灭绝。,23/36,On the other hand,there are those,like George Hambley,who are opposed to this view,believe that we should not worry about,high levels of carbon dioxide,in the air.在另首先，还有一些人，像科学家乔治汉布利，反对上面观点，他们认为我们无须担心空气中会有高含量二氧化碳。They predict that any warming will be,mild,with few bad,environmental consequences.,他们预言说，变暖情况不会很严重，对环境影响也不会太坏。,In fact,Hambley states,More carbon dioxide is actually a,positive,thing.It will make plants grow quicker;crops will produce more;it will encourage,a greater range of,animals-,all of which will make life for human beings better.,汉布利实际上是这么说：“二氧化碳含量增加实际上是件好事，它使植物成长更加快，庄稼产量更高，还会促进动物生长全部这些都能改进人类生活。”,a greater range of 更大范围,24/36,The different ideas between Dr.Janice Foster&George Hambley,Dr.Janice Foster,George Hambley,Carbon dioxide has caused the global temperature to _,上升,_.An increase of five degrees would be a _,灾难,_ and could be _,非常严重,_.,More carbon dioxide is a _ thing,which makes crops _,产量更多,and will encourage _.,go up,catastrophe,very serious,positive,produce,more,a greater range of animals,25/36,Does,global warming,matter?,Positive effects,Negative effects,26/36,cause the sea level to rise,severe storms,floods,droughts,famines,the spread of diseases,disappearance of species,Positive effects,Negative effects,27/36,cause the sea level to rise,severe storms,floods,droughts,famines,the spread of diseases,disappearance of species,Positive effects,Negative effects,make plants grow quicker,crops will produce more,a greater range of animals,make life better,28/36,Greenhouse gases continue to,build up,in the atmosphere.,温室气体继续在大气层中,聚集,。,Even if,we start reducing,the amount of,carbon dioxide and other greenhouse gases,the climate is going to,keep on,warming,for decades or centuries,.即使我们开始降低二氧化碳和其它温室气体含量，在（未来）几十年或几个世纪内，气候仍会连续转暖。No one knows the effects of global warming.没有些人知道全球变暖带来什么样影响。Does that mean we should do nothing?这是不是意味着我们就无须采取任何办法呢？Or,are the risks too great?还是说，这么不采取任何办法危险性会很大呢？,29/36,4.Which of the following statements is True?,Burning fossil fuels causes the global,warming.,B.We will have more food with global,warming.,C.Global warming means disasters to,humans.,D.More greenhouse gases will gather in the,atmosphere.,30/36,True or false?(,P27,),scanning,Reading Comprehension III,2,The temperature in the last century didnt,seem to increase much.,2.Everyone believes that global warming is,caused by the activities of humans.,3.Janice Foster believes she can measure the,future global rise in temperature.,4.The rise in carbon dioxide is causing a steady,increase in global warming.,5.George Hambley believes that global warming,will do good rather than harm to the earth.,6.It is clear what the effects of global warming,will be.,31/36,1.Although we are burning _,coal every year,we wont _ of it,for
