10、ffee.Look,it is sunny today,isnt it?Yeach,I like sitting in the sun, drinking coffee and listening to the light music.You really know how to lead a comfortable life and enjoy yourself.A piece of bad news for you: Iits forecasted that it will be cloudy tomorrow.Its so changeable!Maybe the day after t

11、omorrow,it will be snowy.Youre such a smart boy.It is predicted to snow.Really?Thats great!If so,we can buy a roll of film to take photos,and invite our friends Amy,Martin and Sally to play with snowballs.And we can also heap up a snowman standing on our playground!So it is not bad but good news.May

12、 your dream come true.Wang Lin is talking with Alice about the recent weather.How are you doing these days?Fine,and you?Me too.Its so hot and muggy today.Yes.The weather has been dry for days.Its reported that the temperature today rises to about 40C.Oh,I see.The heat makes my flowers fade,my little

13、 dogGegeis lying on the ground with its tongue strectching long.God damn!Could you remember the flood last month?Sure.It was raining cats and dogs.Luckily I was staying at home that day.A terrible flood.Some people lost their lives.Poor poeple!The flood is dangerous,and our government ha asked peopl

14、e to be mindful of heat,extreme heat may also cause death.Take it easy.The fall is coming and the heat will be finally over.I hope so.Yang Ming asks his teacher,Mr.Zhang,some questions about the climate.Good morning,Mr.Zhang.Good morning,any questions?Yes,could you tell me the difference of climate

15、between Beijing and Kunming?Of course.Beijing is situated in the North and Kunming in the Southwest.Is the climate related to the latitude?Yes,Beijing is in the high latitudes while Kunming in the low latitudes.Does the latitude influence the temperature?Certainly,its colder in Beijing than in Kunmi

16、ng as a whole.The weather in Beijing is very bad.How?Can you explain it in detail?Its cloudy and windy.Through the whole year,the wind blows very hard.The dirt spreading in the air can make people dirty.It can even get through the window and fall on your furniture.But the strong wind offers a good c

17、hance to fly kites.What about Kunming?Its warm and sunny.The weather si agreeable,comfortable and humid.The range of temperature is unnoticeable.In short,that means its like spring all the year round.Youre right.Thank you very much.Aaron is calling his girlfriend,Helen.Darling,what are you busy with

18、 now?I am missing you very much.Next week,I have a 3-day vacation.Lets make a trip.Great!Where do you like to go?The South or the North?The temperature in the North is below zero.The worst is that it has sonowed there for days.But I enjoy the cold weather.It must be refreshing after a hot and muggy

19、summer we spent.It was terribly hot indeed.If we go southward,its unnecessary to travel with more clothes,the weather is fairly agreeable!Cold as it is in the North,we can seize the opportunity to ski.Skiing is so exciting and challenging!Ok,this time,Ill follow you.Next time,lets go travelling in t

20、he South for surfing.passage Our Changing AtmosphereAccording to the National Academy of Sciences,the Earths surface temperature has risenby about 1 degree Fahrenheit in the past century,with accelerated warming during the past two decades.There is new and stronger evidence that most of the warmingo

21、ver the last 50 years is attributable to human activities.Human activities have altered the chemical composition of the atmospherethrough the buildup of greenhouse gases-primarily carbon dioxide,methane,and nitrous oxide.Energy from the sun drives the earths weather and climate,and heats the earths

22、surface;in turn,the earth radiates energy back into space.Atmospheric greenhouse gases(water vapor,carbon dioxide,and other gases)trap some of the outgoing energy,retaining heat somewhat like the glass panels of a greenhouse.Without this naturalgreenhouse effect,temperatures would be much lower than

23、 they are now,and life as known today would not be possible.Thanks to greenhouse gases,the earths average temperature is a more hospitable 60F.However,problems may arisewhen the atmospheric concentration of greenhouse gases increases.Scientists generally believethat the combustion of fossil fuels an

24、d other human activitiesare the primary reason for the increased concentration of carbon dioxide.What has changed in the last few hundred yearsis the additional release of carbon dioxide by human activities.Fossil fuels burned to run cars and trucks,heat homes and businesses,and power factories are

25、responsible for about 98% of US carbon diozide emissions,24% fo methane emissions,and 18% of nitrous oxide emissions.Increased agriculture,deforestation,landfills,industrial production,and mining also contribute a significant share of emissions.In 1997,the United States emitted about one-fifth of to

26、tal global greenhouse gases.The 20th centurys 10 warmest yearsall occurred in the last 15 years of the century.Of these,1998 was the warmest year on record.The snow covers in the Northern Hemisphereand floating ice in the Arctic Ocean have decreased.Globally,sea level has risen 4-8 inches over the p

27、ast century.Worldwide precipitation over land has increased by about one percent.The frequency of extreme rainfall eventshas increased throughout much of the United States.Increasing concentrations of greenhouse gasesare likely to accelerate the rate of climate change.Scientists expect that the aver

28、age global sirface temperaturecould rise 1-4F(0.6-2.5C)in the next fifty years,and 2.2-10F(1.4-5.8C)in the nxt century,with significant refional variation.Evaporation will increase as the climate warms,which will increase average global precipitation.Soil moisture is likely to decline in many region

29、s,and intense rainstorms are likely to become more frequent.Sea level is likely to ris two feet along most of the US coasts.Calculations of climate change for specific areas much less reliable than global ones,and it is unclear whether regional climate will become more variable.Words and Expressions

35、 holiday now.Where would you like to go,the North or the South?I prefer the South to the North.Its more agreeable-sunny and warm.5.The temperature today is 20C.That means it is 2C higher than that of yesterday,1C lower than that of the da before yesterday.BDo you want to know something about the his

36、tory of weather?Dont look at the sky.Donts look for the old weather report.Looking ar tree rings is more important.Correct weather reports date back to only one century,but some trees cn provide an exact record of the weather even further back.Its natural that a tree would grow bestin a climate with

37、 plenty of sunlight and rainfall.It is also expected that little sunlightor rainfall would limit the growth of a tree.The changes from a favorable to an unfavorable climatecan be determined by reading the pattern of ring in a tree trunk.To find out the weather of ten years ago,count the rings of a t

38、ree trunk form the outside to the inside.If the tenth ring is far from the other rings,then it si certain that plenty of sunny and rainy weather occurred.If the rings are close together,then the climate was bad for the tree.Studying tree rings is not only important for the history of the weather,but

39、 also for the history of man.In a region of New Mexico you can find only sand-no trees and no people.However,many centuries ago a large population lived there.They left suddenly,why?A scientist studied patterns of dead tree rings which had grown there.He decided the people had to leave because they

40、had cut down all the trees.Trees were necessary to make filrs and buildings.So,after the people destroyed the trees,they had to move.Supplementary Reading Extreme WeatherExtreme weather will become more common,experts forecast.NEW YORK It has been a summer of extremes.Rains have deluged Europe and A

41、sia,swamping cities and villages and killing abot 2 000 people.while drought and heat have seared the American Western and Eastern cites.What is going on?The floods and droughts could simply be flickersin the inherently chaotic weather system,some experts say.But many warn that such extremeswill be

42、increasingly common as the world grows warmer.Such a shift could pose big problems in places where water is alreadya strained resource,they say.A warmer world is more likely to be a wetter one,experts warn,with more evaporation resulting in more rains,in more heavy and destructive downpours.But in a

43、 troublesome twist,that world may also include more intense droughts,as the increased evaporation parches soils between occasional storms.In a hotter climate,your chances of being caught with either too muchor too little rains are higher,said John Wallace,a professor of atmospheric sciences at the U

44、niversity fo Washington.And the globe is getting warmer.The last several decades of global temperature readingscurve up on graphs like the end of a hockey stick.Climate specialists concluded for the first time last yearthat humans were causing most of the warming trend by burning coal and oil,which

45、release carbon dioxide and other heat-trapping greenhouse gases.The main way that warming is likely to manifest itself,scientists say,is through changes in the balance of water as liquid,vapor and ice.There si growing evidence now that shifts in the golbal water cycleare likely to cause potentially

46、catastrophic effectsin several parta of the world,said Rajendra Pachauri,an Indian engineer who si the new chairmanof the Intergovernmental Panel on Climate Change.Still,a scientific debate persists.Some speciallists say the earth has built-in buffering mechanismsthat can limit extremes.But manyy ot

47、her say that past records,current trends and computer models all point to big changes ahead.One new study this summer found evidence that Asian monsoon,as a part of falter in arid,subtropical areas intensified.Generally,agriculture is expected to falter in arid,subtropical areas like the eastern Mediterranean and southern Africa,while flourishing in northern climes,like the North American wheat belt,as more precipitation and longer growing seasons boost yields.But climate specialists say that even there rainis more likely to fall as field-scouring torrents.Long-term planne
