A greenhouse is a building made of glass which is used for keeping plants when the outside temperature is low. In a similar way there are several gases in the atmosphere which trap(捕捉)the heat produced by the sun and prevent it from escaping. These gases are known as"greenhouse gases"，and the way in which they trap heat in the atmosphere is called the "greenhouse effect". This is not simply air pollution. Most of the main greenhouse gases exist naturally in small amounts in our atmosphere, and without them earth would be 30 degrees colder and human life would not exist. In other words, the greenhouse effect is a natural course which is to some degree helpful to us.The problem is that in the last century and a half, we have been putting too many of these gases into the earth's atmosphere by burning large quantities of coal and oil and by cutting down forests. The rapid increase in greenhouse gases is making the world warmer. The world's temperature has already gone up by half a degree this century, and the sea level has risen by 10 centimetres. If the amount of carbon dioxide(二氧化碳)in the atmosphere doubles, there will probably be a rise in the earth's temperature of between 1 and 4 degrees. This may seem a small increase, but it would be enough to cause major changes in geography and agriculture. Large areas of the world would be flooded, and some areas would become dry and unable to produce crops. It is important, too, to consider that there may be a delay of about 30 years in the greenhouse effect. This means that we are probably experiencing only now the effect of the gases put into the atmosphere before the 1960s. Since then, our use of these gases has greatly increased.1. The"greenhouse effect"means _____.A. the way in which gases are used for keeping plants warmB. a natural course which is some degree helpful to usC. the way"greenhouse gases"trap heat on the earthD. the whole course in which greenhouse gases prevent heat2. If there were no greenhouse effect, _____.A. no plants would grow on our planetB. earth would be thirty degrees colderC. man could not live on the earthD. All of the above answers are correct3. Which of the following is NOT true? _____A. Burning too much coal and oil produces lots of greenhouse gases.B. It has become warmer on the earth now than in the past.C. Gases put into the atmosphere now will affect the earth years later.D. The temperature in a greenhouse is as high as that in the atmosphere.4. Suppose the earth's temperature rose by 3 degrees, _____.A. great harm would be done to mankindB. the sea level would go by 10 centimetresC. all the land in the world would be floodedD. crops would be unable to grow on the earth5. This passage mainly deals with _____.A. the concept(概念)and harm of greenhouse effectB. the relation between greenhouse gases and manC. the concept and change of greenhouse effectD. the effect of the rise of the earth's temperature

EL NinoWhile some forecasting methods had limited success predicting the 1997 EL Nino（厄尔尼诺现象，指赤 道东太平洋南美沿岸海水温度剧烈上升的现象。) a few months in advance , the Columbia University researchers say their method can predict large EL Nino events up to two years in advance.That would be good news for governments,farmers and others seeking to plan for the droughts and heavy rainfall that EL Nino can produce in various parts of the world.Using a computer,the researchers matched sea-surface temperatures to later EL Nino occurrences（发 生）between 1980 and 2000 and were then able to anticipate EL Nino events dating back to 1857,using priorsea-surface temperatures.The results were reported in the latest issue of the journal Nature.The researchers say their method is not perfect , but Bryan C. Weare , a meteorologist（气象学家）at the University of California,Davis,who was not involved in the work,said it"suggests EL Nino is indeed predictable"."This will probably convince others to search around more for even better methods,"said Weare.He added that the new method " makes it possible to predict EL Nino at long lead（提前的）times ". Other models also use sea-surface temperatures,but they have not looked as far back because they need other data, which is only available for recent decades,Weare said.The ability to predict the warming and cooling of the Pacific is of immense importance.The 1997 EL Nino , for example , caused an estimated $20 billion in damage worldwide , offset（抵消）by beneficial effects in other areas,said David Anderson,of the European Centre for Medium-Range Weather Forecasts in Reading , England. The 1877 EL Nino , meanwhile , coincided（同时发生）with a failure of the Indian monsoon and a famine that killed perhaps 40 million in India and China,prompting the development of seasonal forecasting,Anderson said.When EL Nino hit in 1991 and 1997,200 million people were affected by flooding in China alone, according to a 2002 United Nations report.While predicting smaller EL Nino events remains tricky（复杂的）, the ability to predict larger ones should be increased to at least a year if the new method is confirmed.EL Nino tends to develop between April and June and reaches its peak between December and February.The warming tends to last between 9 and 1 2 months and occurs every two to seven years.The new forecasting method does not predict any major EL Nino events in the next two years,although a weak warming toward the end of this year is possible.In 1997,EL Nino caused about $20 billion in damage worldwide.A:RightB:WrongC:Not mentioned

第二篇Around 45%of the UK's carbon dioxide emissions come from the energy people use every day-at home and when they travel.In order to generate that energy,fossil fuels(coal oil,and gas)are burnt,and these produce greenhouse gases-in particular carbon dioxide(CO2).Car emissions are a major problem, but the truth is that more CO2 comes from the energy used at home.The average household creates aroundfive and a half tonnes of CO2 a year,and it is the same CO2 that is changing the climate and damaging the environment.CO2 and various other gases wrap the earth in an invisible blanket helping to prevent heat from escaping.Without this greenhouse effect,the average temperature on Earth would be around-18℃， compared with the current average of around+15℃．The composition of this blanket of gases has remained relatively constant for many thousands of years.However,since the industrial revolution began around 200 years ago,people have been burning increasing amounts of fossil fuels,thus releasing more CO2 and other greenhouse gases in the process.This has increased the heating effect of the blanket,trapping more of the sun's energy inside the Earth's atmosphere in turn the Earth's temperature has increased more rapidly in a shorter period of time than it has for thousands of years.In 2008,the total UK CO2 emissions were 533 million tonnes.27%(144 million tonnes)of those emissions came from the energy used to heat,light,and power homes.Transport emissions caused by passenger cars,buses and motorcycles accounted for a further 16%(87 million tonnes)of the UK's CO2 emissions.These figures show that a significant amount of CO2 results from ordinary citizens carbon footprint in their daily activities and lifestyle.The effects of climate change can be seen all around us.Weather patterns are becoming more and more fractured and uncertain,and over the last century trends in warm weather have become increasingly common.In the UK in the last 40 years,winters have grown warmer,with much heavier rainfall.One of the clearest shifts over the last 200 years is towards summers that are hotter and drier,causing pervasive（普遍的）water shortages.Recent years have been the hottest since records began and during August 2003,the hottest ever outdoor temperature in the UK was recorded-38.5℃．What is the author's opinion about the level of CO2 emissions in the UK?A:The majority of CO2 emissions come from motorized transport.B:CO2 emissions may cause climate change in the future.C:More CO2 emissions come from homes than from cars.D:The average citizen does not create much CO2.

At the first sight the planet Mars does not appear very welcome to any kind of life．It has very little oxygen and water,the temperature at night is below-50~Cand winds of 100 miles per hour cause severe dust storms．However,the surface of the planet seems to show that water flowed across it some time in the past,and it is believed that there is enough ice at the poles to cover the planet with water if it melts．Although there is no life on the Mars now,some scientists think that there may have been some form of life long time ago．At that time,the planet had active volcanoes;the atmosphere was thicker and warmer;and there was water．In fact,in some ways the Mars may have been similar to the Earth,where life exists.
Some people believe that the Mars could support life in the future if the right conditions were produced．The first step would be to warm the planet using certain gases which trap the Sun's heat in the planet's atmosphere．With warmth,water and carbon dioxide(二氧化碳),simple plants could begin to grow．These plants could slowly make the Mars more suitable for living．It is estimated that the whole process might take between 100,000 and 200,000 years．In the meantime,people could begin to live on the planet in special closed environments．They would provide a lot of useful information about conditions on the Mars and the problems connected with living there.
There could be life on the Mars in the future ifA.it supported life in the past
B.certain gases are used to cool the planet
C.the atmosphere can be heated enough to grow simple plants
D.the planet's volcanoes become as active as they were in the past
