[单选题]Text l Americans,we are told,believe in competition.But a shockingly large number of workers-30 million-are shackled by what are called"noncompetes,"which are agreements forbidding employees to leave their job to work for a competitor or to start their own competing business.And the number is growing fast.Once reserved for a corporation's most treasured rainmakers,noncompetes are now routinely applied to low-wage workers like warehouse employees,fast-food workers and even dog sitters.Like other anti-competitive practices,they poison our economy in larger,less perceptible ways.A report from the Treasury Department suggests that noncompetes should be banned for all employees,regardless of skill,industry or wage;they simply do more harm than good.Because laws governing noncompetes vary from state to state,we can analyze the effects of these kinds of contracts on wages,competition and labor mobility.The evidence shows wages in states that enforce noncompetes are 10 percent lower than in states that restrict their use.The Treasury Department concluded in its recent report that"by reducing workers'job options,noncompete agreements force workers to accept lower wages in their current jobs,and may sometimes induce workers to leave their occupations entirely,forgoing accumulated human capital."Workers shackled by noncompetes cannot rely on outside offers and free-market competition to fairly value their talents.Without incentives to increase wages in-house,companies can allow salaries to plateau.California and Massachusetts offer a case study within the high-tech industry.California strictly voids all noncompete agreements.Massachusetts,like most other states,enforces noncompetes.Both states enjoyed an early boom within the high-tech market,but California's Silicon Valley has continued growing,while Massachusetts has sputtered.In Massachusetts the enforcement of those agreements kept out new businesses by preventing people most likely to start new businesses-experienced former employees-from staying in the region.Meanwhile,in Silicon Valley,entrepreneurial activity flourished;thanks to California's refusal to enforce all noncompetes（including those from other jurisdictions）,it remains the tech center of the world.The best companies already realize the damaging effect of post-employment restrictions.Companies with little turnover risk becoming stagnant and short-sighted.In fact,relying on noncompetes rather than active recruitment and retention creates a market for lemons-a business will end up with employees who stay despite their unhappiness.Smart leaders treat departing employees as alumni,rather than sour exes in a divorce.But too many other employers have become increasingly inclined to bring disagreements with their former employees to court,relying on noncompetes rather than positive incentives to retain the best talent and reduce the competition.The liberty to move in the job market not only supports workers'choice,equality and wage growth but also creates the competition that catalyzes entrepreneurship,innovation and overall economic growth.If we want a healthy and free market,we should not shackle workers to the first business that offers them a job.Let them compete. The word"shackled"（Line 2,Para.1）is closest in meaning to____.
A.authorized
B.united
C.guided
D.bound

[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. 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.

[单选题]Text l If comfortably outpacing your rivals is the main measure of automotive achievement,Tesla's electric car is a resounding success.The Model S last year outsold its nearest luxury rival,Mercedes's petrol-engined S-class,by 30qo in America.And in its top specification the Tesla will also beat the Cerman car in the race from 0-60mph.As a battery-maker Tesla is also moving fast.This week it announced plans to build a"gigafactory"in America to make lithium-ion power-packs,that it hopes will propel its vehicles to the mainstream.Tesla's acceleration has been rapid.Launched a decade ago by Elon Musk,a founder of PayPal and serial tech entrepreneur,last year it sold around 22,000 cars and by the end of 2014 hopes to be making l,000 a week.In early 2015 Tesla will add the Model X,a medium-sized SUV,to its range.However,Tesla's impressive growth has not yet tranalaLed into significant profits.A series of b8ttery fires also briefly dented sales growth last year.Nevertheless,Tesla's shares surged on February 25th,to value the company at over$30 billion after Morgan Stanley,a bank,joined its adoring fans.It reckons that the battery factory will not only propel it along the road to mass manufacturing but also make it a leading competitor in low-cost enerOr storage,Lhe key to making renewable energy more practical.The bank is also confident that Tesla's Silicon Valley location will put it in the driverless front seat of autonomous motoring.A recent meeting with Apple,and the iPad-like control panel of the Model S,have convinced some ob~servers that a takeover-and an iCar are around the corner,although Mr Musk insists that his firm is not for sale.Tesla has defied its doubters with the success of the Model S,a smartly styled luxury car.It may not share the outrageous looks of a supercar like the Lamborghini Aventador,but it has the performance without the$400,OOO-plus price tag.The most basic Model S costs$64,000 in America.This has won it rave reviews in the motoring press,often sniffy about other electric cars with limited ranges and duff looks.By designing a large car wiLh a big battery pack,Tesla has diminished"range anxiety"-one version can d0 310 nules（500km）between charges. Which one of the following is true about Tesla's ModelS?
A.It has duff looks and limited range.
B.It looks as impressive as other super cars.
C.It is not worth spending so much money on it.
D.It has changed people's view towards the electric car.
