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 2035Fossil fuel giants____.A.are expressing dissatisfaction with carbon pricing schemesB.are reducing their dependence on dirty energy sourcesC.view clean renewable energy as their future source of profitsD.see carbon pricing as distraction from tough rules against them

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.To maintain forests as valuable“carbon sinks,”we may need to_______.《》（）A.preserve the diversity of species in themB.accelerate the growth of young treesC.strike a balance among different plantsD.lower their present carbon-absorbing capacity

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
