Passage ThreeHow can we get rid of garbage.9 Do we have enough energy sources to meet our future energy needs?These are two important questions that many people are asking today. Some people think that man might be able to solve both problems at the same time. They suggest using garbage as an energy source, and at the time it can save the land to hold garbage.For a long time, people buried garbage or dumped it on empty land. Now, empty land is scarce. But more and more garbage is produced each year. However, garbage can be a good fuel to use. The things in garbage do not look like coal, petroleum, or natural gas; but they are chemically similar to these fossil fuels. As we use up our fossil-fuel supplies, we might be able to use garbage as an energy source. Burning garbage is not a new idea. Some cities in Europe and the United States have been burning garbage for years. The heat that is produced by burning garbage is used to boil water. The steam that is produced is used to make electricity or to heat nearby buildings. In Paris, France, some power plants burn almost 2 million metric tons of the cities garbage each year. The amount of energy produced is about the same as would be produced by burning almost a half million barrels of oil.Our fossil fuel supplies are limited. Burning garbage might be one kind of energy source that we can use to help meet our energy needs.44. What two problems can man solve by burning garbage?A. The shortage of energy and air pollution.B. The shortage of energy and the land to hold garbage.C. Air pollution and the shortage of fossil fuel.D. Air pollution and the shortage of land to hold garbage.

共用题干第二篇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℃.CO2 emissions from vehicles_______.A:are a more serious problem than energy shortageB:do not cause any problemsC:are high because the average household owns a carD:contribute considerably to greenhouse gases

共用题干Natural Gas1 Natural gas is produced from reservoirs deep beneath the earth's surface. It is a fossil fuel(矿物燃 料),meaning that it is derived from orgaiiic material buried in the earth millions of years ago.The main corn- ponent of natural gas is methane(甲烷).2 The popularity and use of clean natural gas have increased dramatically over the past 50 years as pipeline infrastructure(基础设施)has been installed to deliver it conveniently and economically to millions of residential,commercial and industrial customers worldwide.Today,natural gas service is available in all 50 states in the U.S.,and is the leading energy choice for fueling American homes and industries.More than 65 million American homes use natural gas.In fact,natural gas is the most economical source for home energyneeds,costing one-third as much as electricity.In addition to heating homes,much of the gas used in the United States is used as a raw material to manufacture a wide variety of products,from paint,to fibers for clothing,to plastics for healthcare,computing and furnishings.Natural gas is also used in a significant number of new electricity-generating power plants.3 Natural gas is one of the safest and cleanest fuels available. It emits(发出)less pollution than other fossil fuel sources. When natural gas is burned , it produces mostly carbon dioxide(二氧化碳)and water va- por一the same substances emitted when humans breathe.Compared with some other fossil fuels,natural gas emits the least amount of carbon dioxide into the air when combusted(燃烧)一making natural gas the clea-nest burning fossil fuel of all.4 The United States consumes about one一third of the world's natural gas output,making it the largest gas-consuming region in the world.The U.S.Department of Energy Information Administration forecasts that natural gas demand will grow by more than 50 percent by 2025.5 There are huge reserves of natural gas beneath the earth's surface.The largest reserves of natural gas can be found in Russia , West and North Africa and the Middle East. LNG(液化天然气)has been pro- duced domestically and imported in the United States for more than four decades.Today,the leading import- ers of LNG are Japan,Korea,France and Spain.Paragraph 3__________A:Popularity and Use of Natural GasB:Natural Gas Reserves and SupplyC:Natural Gas PricesD:Clean Fuel of ChoiceE:Disadvantages of Natural GasF:Natural Gas Consumption

Text 3 Recently,a coalition of business and advocacy groups from around Washington gathered to kick off a campaign to enact a carbon pricing program Known as the Climate and Community Reinvestment Act of D.C.,the plan would place a new tax on all fossil fuels bought or sold,with the hope of ultimately discouraging the use of these polluting energy sources.The big-picture goal of this campaign is admirable:to address the everdeepening crisis of climate chaos by dissuading the continued use of coal,oil and gas.But unfortunately,the approach-one based in a world of financial markets,trading schemes and enticing new public revenue streams-is inherently flawed.Simply put,carbon pricing is a false solution to climate change and a distraction from real,effective climate solutions we must urgently pursue.To date,there is scant evidence to indicate that carbon taxes lower greenhouse gas emissions.In fact,the opposite is true.Recently Food&Water Watch reviewed the British Columbia carbon tax program,often cited by advocates as an example of success.From 2009(the first full year of the tax)t0 2014,emissions from taxed sources grew by 4.3 percent.And in the seven years after the carbon tax took effect,total gasoline sales increased by 7.37 percent.Supporters of such plans like to focus on a deceivingly simple notion that increasing the price of a consumer good will automatically reduce its use.But this just isn't the case when it comes to the purchase of necessities.People must heat their homes in winter,and they must commute to work,regardless of the cost.Those backing the D.C.carbon pricing plan like to note that revenue from the new tax would go toward investment in clean energy sources.But only 20 percent of the generated funds would be allocated in this manner.The rest would be shared out in tax breaks for businesses and rebates for consumers,another factor undercutting the notion that increased costs up front would change consumer behavior in the long run.Meanwhile,fossil fuel giants such as ExxonMobil are increasingly coming out in support of carbon pricing.This should be cause for alarm for anyone concerned with stamping out the use of the dirty energy sources these corporations profit from.Exxon knows that carbon taxes will do little to change the business-as-usual dependence on oil and gas that it relies on to continue operating and enriching shareholders.Furthermore,corporations such as Exxon rightly view carbon pricing schemes as a means of diverting energy and interest from tougher regulations that might actually encroach on their business plans and bottom lines.Despite what well-intentioned activists want to believe,there is no convenient,market-friendly solution to our serious climate condition.There is only the hard truth that we must tackle the problem at its source:We must stop using fossil fuels,and soon.The latest science indicates that in order to avoid the worst effects of deepening climate chaos,society must transition completely to clean,renewable energy by 2035.Which of the following is true,according to Paragraphs 4 and 5?A.Consumers will use less of a good when its price increases.B.Carbon taxes will benefit the development of clean energy.C.Increased cost will do little to change the use of necessities.D.The dependence on fossil fuels will decrease automatically.

Forests give us shade,quiet and one of the larder callenges in the fight against climate change.Even as we humans count on forests to soak up a good share of the carbon dioxide we produce,we are threatening their ability to do so.The climate change we are hastening could one day leave us with forests that emit more carbon than they absorb.Thankfully,there is a way out of this trap-but it involves striking a subtle balance.Helping forests flourish as valuable“carbon sinks”long into the future may require reducing their capacity to absorb carbon now.California is leading the way,as it does on so many climate efforts,in figuring out the details.The state’s proposed Forest Carbon Plan aims to double efforts to thin out young trees and clear brush in parts of the forest.This temporarily lowers carbon-carrying capacity.But the remaining trees draw a greater share of the available moisture,so they grow and thrive,restoring the forest’s capacity to pull carbon from the air.Healthy trees are also better able to fend off insects.The landscape is rendered less easily burnable.Even in the event of a fine,fewer trees are consumed.The need for such planning is increasingly urgent.Already,since 2010,drought and insects have killed over 100 million trees in California,most of them in 2016 alone,and wildfires have burned hundreds of thousands of acres.California plans to treat 35,000 acres of forest a year by 2020,and 60,000 by 2030-financed from the proceeds of the state’s emissions-permit auctions.That’s only a small share of the total acreage that could benefit,about half a million acres in all,so it will be vital to prioritize areas at greatest risk of fire or drought.The strategy also aims to ensure that carbon in woody material removed from the forests is locked away in the form of solid lumber or burned as biofuel in vehicles that would otherwise run on fossil fuels.New research on transportation biofuels is already under way.State governments are well accustomed to managing forests,but traditionally they’ve focused on wildlife,watersheds and opportunities for recreation.Only recently have they come to see the vital part forests will have to play in storing carbon.California’s plan,which is expected to be finalized by the governor next year,should serve as a model.By saying“one of the harder challenges,”the author implies that_______.《》()A.global climate change may get out of controlB.people may misunderstand global warmingC.extreme weather conditions may ariseD.forests may become a potential threat

共用题干Green Energy1.Green energy is energy that is produced in a manner that has, less of a negative impact to the environment than energy sources like fossil fuels,which are often produced with harmful side effects."Greener" types of energy that often come to mind are solar,wind,geothermal and hydro energy.There are several more,even including nuclear energy,that is sometimes considered a green energy source because of its lower waste output relative to energy sources such as coal or oil.2.The goal of green energy is generally to create power with as little pollution as possible produced as a by-product. Every form of energy collection will result in some pollution,but those that are green are known to cause less than those that are not. Most people who advocate greener sources of energy claim that the result of worldwide use of green energy will result in the ability to preserve the planet for a longer time.Greenhouse gases,a by-product of traditional sources of energy such as fossil fuels are thought to be causing global warming,or the process of the Earth heating up at an accelerated pace.3.It is not completely necessary for green energy sources to come from places like solar or wind fields,which are examples of green"power plants".A green energy source can be a building that is designed in a way that it keeps itself cool in the daytime and heated in the night through its architectural design rather than having an air-conditioning or a heating system. The conservation of energy through architectural(建筑学的)design becomes, itself, a green energy source. Similarly, many sources of green energy can come directly from the area in which the energy is needed rather than from an outside source.4.One of the goals of green energy technology is to take existing fossil fuel energy technology and clean it up so it is produced more cleanly. One such case is that of clean coal technology,where scientists are trying to find ways to extract energy from coal and other fossil fuels without all of the harmful side effects.The success of such these types of green energy depend upon the ability to extract harmful by-products from fossil fuels while not only being energy efficient,but by being cost efficient as well.Greenhouse gases are thought to be causing______.A:global warmingB:carbon emissionC:lower waste outputD:a green energy sourceE:fossil fuels F: clean fuels

共用题干Green Energy1.Green energy is energy that is produced in a manner that has, less of a negative impact to the environment than energy sources like fossil fuels,which are often produced with harmful side effects."Greener" types of energy that often come to mind are solar,wind,geothermal and hydro energy.There are several more,even including nuclear energy,that is sometimes considered a green energy source because of its lower waste output relative to energy sources such as coal or oil.2.The goal of green energy is generally to create power with as little pollution as possible produced as a by-product. Every form of energy collection will result in some pollution,but those that are green are known to cause less than those that are not. Most people who advocate greener sources of energy claim that the result of worldwide use of green energy will result in the ability to preserve the planet for a longer time.Greenhouse gases,a by-product of traditional sources of energy such as fossil fuels are thought to be causing global warming,or the process of the Earth heating up at an accelerated pace.3.It is not completely necessary for green energy sources to come from places like solar or wind fields,which are examples of green"power plants".A green energy source can be a building that is designed in a way that it keeps itself cool in the daytime and heated in the night through its architectural design rather than having an air-conditioning or a heating system.
