2.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.

    Text 1 Giant corporations often claim to be"green,"pointing to programs they've undertaken aimed at being environmentally conscious.But sometimes these efforts don't really amount to much.They can be no more than'igrcenwashing,"a public relations effort that doesn't represent any fundamental shift in thinking.But such a change may actually be going on among several of the world's largest fossil fuel companies,namcs such as ExxonMobil,Shell,and BP.One of the biggest reasons:pressure from the companies'sharcholdcrs.Investors arc asking corporations to make more transparent the effects climate change will have on their businesses,as well as explain what they are doing to reduce their greenhouse gas emissions.While sharcholdcr motivcs are cerlainly aimed at helping in the worldwide fight against global warming,they also represent a practical need to better understand a company's prospects.If the burning of oil and gas is grcaily curtailed as a result of the December 2015 intemational Paris climate agreement,for example,how might that affect the bottom line of a corporation whose chief source of revenue is extracting and selling carbon-emitting oil and gas?Or,conversely,how is a company planning to take advantage of the business opportunities that emerge from a shift away from fossil fuels?Climate Action 100+,for example,is a shareholder action group that is asking corporations to make stronger commitments to meeting the 80 percent cut in carbon emissions proposed by the Paris agreement signed two years ago by nearly 200 nations.Some 225 investment groups who manage more than S26.3 trillion have signed on in support.Last week,intemational energy giant ExxonMobil said it will step up its reporting to shareholders and the public about the impacts climate change will have on its business,including any expected increased risks.The new policy follows a vote by ExxonMobil investors at the company's annual meeting in May that called for a yearly assessment of the effects of climate change on the company.The new position represents a sea change for ExxonMobil,which until the early 2000s had disputed the need to take action on climate change.Around the world national govemments are shaping new policies in an effort to reduce greenhouse gas emissions to a level that will not allow global temperatures to rise more than 2 degrees Celsius.In the U,S.,individual states and cities are pursuing lawsuits against companies that fail to deal responsibly with greenhouse gas emissions,which they contend harm the public.22.Which of the following is right about shareholders?

    A.They explained their steps to reduce greenhouse gas emissions.
    B.They are reluctant to help fight against global warming.
    C.They have made some corporations'thought changed.
    D.They pointed out their understanding of companies'prospects.

    答案:C
    解析:
    事实细节题。根据定位词定位到文章第二段。原文提到有几家公司正在发生这样的变化,其中一个最大的原因是来自公司股东的压力.C项表述正确,故C项为正确选项。【干扰排除】原文提到投资者要求企业解释他们在减少温室气体排放方面正在做的努力,A项与原文事实不符;原文提到股东的动机在于帮助在全球范围内遏制全球变暖,B项所述与原文不符;D项原文未提及。故均排除。

    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 around
    five 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 shortage
    B:do not cause any problems
    C:are high because the average household owns a car
    D:contribute considerably to greenhouse gases

  • 第6题:

    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.

    答案:C
    解析:

  • 第7题:

    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 control
    B.people may misunderstand global warming
    C.extreme weather conditions may arise
    D.forests may become a potential threat

    答案:D
    解析:
    根据题干By saying“one of the harder challenges,”the author implies that_______.定位到原文第一段第一句,但是我们发现第一段只提到了one of the harder challenges,而没有给出harder challenges指什么,也就是没有给出本题的答案,因此我们需要看第一句后面的句子。第一句是中心句,后面的句子是对第一句进行阐述,根据后面的句子的阐述,我们可知尽管我们人类依靠森林来吸收大量的二氧化碳,但是我们造成的气候变化将会使我们的森林最终会释放的碳比吸收的碳还要多。也就是D选项所说的森林可能会成为潜在的威胁。因此答案为D选项。

    Green Energy

    1.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 warming
    B:carbon emission
    C:lower waste output
    D:a green energy source
    E:fossil fuels
    F: clean fuels

    答案:A
    解析:
    文中第一段第一句中Green energy is energy that is…这种表述方法符合科学说明文的记叙方式,首先对一个名词进行科学定义,所以本题答案为D。
    文中第二段第二句: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.任何形式的能源收集都会产生一定程度的污染,但是绿色能源比其他能源造成的污染要少。可以推测出这一段是在讲绿色能源的优点,也就是说为什么要发展绿色能源,所以选择A。
    文中第三段第一句:It is not completely necessary for green energy sources to come from places like solar or wind fields.可以得出,本段主要讲述了我们传统认为的新能源,还有其他种类的新能源,所以选择F。
    文中第四段第一句: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.可以得出,该段主要是在讲新能源的目标和意义。
    第一段最后一句: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.可知,核能经常被视作绿色能源,因为相比煤和石油,它的能源输出效率更高。由此可以得出选项C正确。
    文中第二段最后一句: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.温室气体,一种诸如化石能源的传统能源产生的副产品被认为会导致全球变暖,甚至使地球自转速度加快。因此可以得出A选项正确。
    第三段最后两句:The conservation of energy through architectural 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.通过自身的建筑设计来保存能源本身就是一种绿色能源的来源。同样道理,许多绿色能源可以直接来源于有能源需求的地区内部而不是外部。由此可以得出D选项正确。
    最后一段最后两句: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.这些清洁能源技术的成功取决于人们从化石燃料中排除有害副产品、高效利用能源、同时降低成本的能力。由此可以得出E选项正确。

    C

    It accounted for nearly half of the global increase in emissions in the last decade.

    正确答案: D
    解析:
    录音中在介绍美国是二氧化碳最大排放国时,提到“The U.S., with five percent of the world’s population...”,可知美国人口占据世界人口的5%。
    【录音原文】
      In a recent 12-month span, carbon emissions from the burning of fossil fuels climbed to more than 7, 900, 000, 000 tons, a record high. Global emissions of carbon have been rising steadily since the late 18th century and rapidly since the 1950s. In fact, annual emissions have quadrupled since the mid-20th century.
      Three-fourths of global carbon emissions are the result of burning fossil fuels, namely coal, oil, and natural gas. The rest largely come from deforestation. Of the four major sectors contributing to these emissions, electricity generation—at 35%—accounts for the largest share; transportation and industrial processes, 20%each. The remaining 25%is produced by residential and commercial buildings. Two-thirds of the carbon emissions from fossil fuel combustion are emitted by just 10 nations. The U.S., with five percent of the world’s population, is the largest contributor, accounting for nearly one-quarter of global emissions. China is second, with nearly l4%. Other major polluters are Russia, Japan, India, Italy, Canada, South Korea, Germany, and the United Kingdom.
      Most of the growth in emissions in the coming decades, however, is expected to come from developing countries. While overall global carbon emissions have risen 13%since 1990, those in China have jumped 47%. Indeed, this one country accounts for nearly half of the global increase in emissions in the last decade.

    Text 1 Giant corporations often claim to be"green,"pointing to programs they've undertaken aimed at being environmentally conscious.But sometimes these efforts don't really amount to much.They can be no more than'igrcenwashing,"a public relations effort that doesn't represent any fundamental shift in thinking.But such a change may actually be going on among several of the world's largest fossil fuel companies,namcs such as ExxonMobil,Shell,and BP.One of the biggest reasons:pressure from the companies'sharcholdcrs.Investors arc asking corporations to make more transparent the effects climate change will have on their businesses,as well as explain what they are doing to reduce their greenhouse gas emissions.While sharcholdcr motivcs are cerlainly aimed at helping in the worldwide fight against global warming,they also represent a practical need to better understand a company's prospects.If the burning of oil and gas is grcaily curtailed as a result of the December 2015 intemational Paris climate agreement,for example,how might that affect the bottom line of a corporation whose chief source of revenue is extracting and selling carbon-emitting oil and gas?Or,conversely,how is a company planning to take advantage of the business opportunities that emerge from a shift away from fossil fuels?Climate Action 100+,for example,is a shareholder action group that is asking corporations to make stronger commitments to meeting the 80 percent cut in carbon emissions proposed by the Paris agreement signed two years ago by nearly 200 nations.Some 225 investment groups who manage more than S26.3 trillion have signed on in support.Last week,intemational energy giant ExxonMobil said it will step up its reporting to shareholders and the public about the impacts climate change will have on its business,including any expected increased risks.The new policy follows a vote by ExxonMobil investors at the company's annual meeting in May that called for a yearly assessment of the effects of climate change on the company.The new position represents a sea change for ExxonMobil,which until the early 2000s had disputed the need to take action on climate change.Around the world national govemments are shaping new policies in an effort to reduce greenhouse gas emissions to a level that will not allow global temperatures to rise more than 2 degrees Celsius.In the U,S.,individual states and cities are pursuing lawsuits against companies that fail to deal responsibly with greenhouse gas emissions,which they contend harm the public.21.Big corporations are far away from"green"because

    A.they rarely do anything meaningful.
    B.they don't have any fundamental shift.
    C.they have poor public relations.
    D.they lack fundamental changes in thinking

    答案:D
    解析:
    事实细节题。根据定位词定位到文章第一段。第一段最后一句说明了大公司离“绿色”还很远的原因.即他们所做的努力只不过是“漂绿”,仅仅是为了公共关系,并不代表任何思维方面的根本转变.D项与此文义相符,故D项为正确答案。【干扰排除】原文说它们所开展的环保项目没有什么意义,但是并来说它们很少做有意义的事情,A项属于无中生有;原文说它们在思想上未做出根本转变.B项中“任何”一阋范围过大;C项原文未提及。故均排除。

    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 around
    five 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.

    答案:C

    Natural Gas

    1 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 energy
    needs,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 Gas
    B:Natural Gas Reserves and Supply
    C:Natural Gas Prices
    D:Clean Fuel of Choice
    E:Disadvantages of Natural Gas

    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.

    Green Energy

    1.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.

    The success of green energy depend upon the ability to extract harmful by-products from______.
    A:global warming
    B:carbon emission
    C:lower waste output
    D:a green energy source
    E:fossil fuels
    F: clean fuels

    答案:E
    解析:
    文中第一段第一句中Green energy is energy that is…这种表述方法符合科学说明文的记叙方式,首先对一个名词进行科学定义,所以本题答案为D。
    文中第二段第二句: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.任何形式的能源收集都会产生一定程度的污染,但是绿色能源比其他能源造成的污染要少。可以推测出这一段是在讲绿色能源的优点,也就是说为什么要发展绿色能源,所以选择A。
    文中第三段第一句:It is not completely necessary for green energy sources to come from places like solar or wind fields.可以得出,本段主要讲述了我们传统认为的新能源,还有其他种类的新能源,所以选择F。
    文中第四段第一句: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.可以得出,该段主要是在讲新能源的目标和意义。
    第一段最后一句: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.可知,核能经常被视作绿色能源,因为相比煤和石油,它的能源输出效率更高。由此可以得出选项C正确。
    文中第二段最后一句: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.温室气体,一种诸如化石能源的传统能源产生的副产品被认为会导致全球变暖,甚至使地球自转速度加快。因此可以得出A选项正确。
    第三段最后两句:The conservation of energy through architectural 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.通过自身的建筑设计来保存能源本身就是一种绿色能源的来源。同样道理,许多绿色能源可以直接来源于有能源需求的地区内部而不是外部。由此可以得出D选项正确。
    最后一段最后两句: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.这些清洁能源技术的成功取决于人们从化石燃料中排除有害副产品、高效利用能源、同时降低成本的能力。由此可以得出E选项正确。

  • 第21题:

    问答题
    Although there is disagreement within the scientific community about the extent of global warming, humans would be playing with fire if we were to ignore the danger it poses .As individuals, we can reduce our reliance on fossil fuels, use less electricity and adopt lifestyles that minimize the use of natural resources. On the governmental level, most of the world’s industrialized nations have pledged to cut gas emissions under the Kyoto Agreement in 1997.

    正确答案:
    虽然科学界对全球变暖的影响程度尚有歧见,但若人类对温室效应造成的危险置之不理,无异于玩火自焚。为避免温室效应加剧,从个人角度来看我们可以做的就是降低对化石燃料的依赖、减少用电,并采取最不耗损自然资源的生活方式。在政府这个层面,世界大部份的工业化国家,已在一九九七年所签定的京都议定书中,宣誓将做到气体排放减量。
