In the desert world, the seasons differ from one region to another. The Gohi ,which lies roughly between 35℃ and 55℃ north of the equator, is a good example of seasonal change.
Four seasons are characteristic of the Gobi: spring, summer, fall, and winter, with usually a false spring at the end of winter. These seasons are distinct, with extremes of temperature, as much as 150 between the hottest day in summer and the coldest day in winter.
Spring in the Gobi usually begins about the second week April. For 2 or 3 weeks there is a period of delightful weather, with warm, sunny days and not too much wind. But these are the days of false spring. About the first of May, the tail end of winter returns, and cold, blustery days of dustburdened winds are the rule then, until early or middle June. The latter part of June, for 2 or 3 weeks after the blowy end of winter is the real spring. It spreads its rather comfortable warmth over the desert, and occasional light rains he

[单选题]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. The most suitable title for this text would be_____.
A.The Carbon Tax Fallacy
B.The Climate Change Myth
C.The Call for Clean Energy
D.The Causes of Climate Chaos
