Mark your answers on ANSWER SHEET 1.BText 1/BIn most parts of the world, climate change is a worrying subject. Not so in California. At a recent gathering of green luminariesin a film stars house, naturally, for
11、that is how seriousness is often established in Los Angelesthe dominant note was self-satisfaction at what the state has already achieved. And perhaps nobody is more complacent than Arnold Schwarzenegger. Unlike A1 Gore, a presidential candidate turned prophet of environmental doom, Californias gove
12、rnor sounds cheerful when talking about climate change. As well he might: it has made his political career.Although California has long been an environmentally-conscious state, until recently greens were concerned above all with smog and redwood trees. “Coast of Dreams“, Kevin Stags authoritative hi
13、story of contemporary California, published in 2004, does not mention climate change. In that year, though, the newly-elected Mr. Schwarzenegger made his first tentative call for western states to seek alternatives to fossil fuels. Gradually he noticed that his efforts to tackle climate change met w
14、ith less resistance, and more acclaim, than just about all his other policies. These days it can seem as though he works on nothing else.Mr. Schwarzeneggers transformation from screen warrior to eco-warrior was completed last year when he signed a bill imposing legally-enforceable limits on greenhou

If it were a country it would be the worlds eighth-biggest economy, but only its 16th-biggest polluter. Its big problem is transportmeaning, mostly, cars and trucks, whic
16、h account for more than 40% of its greenhouse-gas emissions compared with 32% in America as a whole. The state wants to ratchet down emissions limits on new vehicles, beginning in 2009. Mr. Schwarzenegger has also ordered that, by 2020, vehicle fuel must produce 10% less carbon: in the production as
17、 well as the burning, so a simple switch to corn-based ethanol is probably out.Thanks in part to California s example, most of the western states have adopted climate action plans. When it comes to setting emission targets, the scene can resemble a posedown at a Mr. Olympia contest. Arizonas climate
18、-change scholars decided to set a target of cutting the states emissions to 2000 levels by 2020. But Janet Napolitano, the governor, was determined not to be out-muscled by California. She has declared that Arizona will try to return to 2000 emission levels by 2012.California has not just inspired o
19、ther states; it has created a vanguard that ought to be able to prod the federal government into stronger national standards than it would otherwise consider. But California is finding it easier to export its policies than to put them into practice at home. In one way, California s self-confidence i
20、s fully justified. It has done more than any other statelet alone the federal governmentto fix Americas attention on climate change. It has also made it seem as though the problem can be solved. Which is why failure would be such bad news. At the moment California is a beacon to other states. If it
21、fails, it will become an excuse for inaction.（分数：10.00）(1).According to the author, Mr. Arnold Schwarzenegger is cheerful chiefly because（分数：2.00）A.climate change is not worrying California anymore.B.even film stars become serious about environmental protection.C.he has benefited personally from Cal
22、ifornias achievements.D.his style of administration is always dominated by self-satisfaction.(2).Why did Mr. Schwarzenegger seem to be working on nothing else?（分数：2.00）A.Because California has always been environmentally-conscious.B.Because Kevin Starr failed to talk about climate change in his book
23、.C.Because his call for alternative fuels has been most strongly echoed.D.Because all his other policies met with more acclaim than resistance.(3).Corn-based ethanol might not be chosen as an alternative because（分数：2.00）A.carbon reduction in both fuel production and burning might be hard.B.Californi
24、a also intends to cut down emissions from new vehicles.C.it is almost impossible for vehicle fuel to produce 10% less carbon.D.Californias corns are chiefly transported by cars and trucks.(4).Janet Napolitano is mentioned in the passage to show that（分数：2.00）A.Arizona is determined to out-muscle Cali

27、antages, is now swimming into even more shark-infested waters, arguing that competition can save even Americas troubled health-care system, the largest in the world. Mr. Porter argues in “Redefining Health Care“ that competition, if properly applied, can also fix what ails this sector.That is a bold
28、 claim, given the horrible state of Americas health-care system. Just consider a few of its failings: America pays more per capita for health care than most countries, but it still has some 45m citizens with no health insurance at all. While a few receive outstanding treatment, he shows in heart-wre
29、nching detail that most do not. The system, wastes huge resources on paperwork, ignores preventive care and, above all, has perverse incentives that encourage shifting costs rather than cutting them outright. He concludes that it is “on a dangerous path, with a toxic combination of high costs, uneve
30、n quality, frequent errors and limited access to care.“Many observers would agree with this diagnosis, but many would undoubtedly disagree with this advocacy of more market forces. Doctors have an intuitive distrust of competition, which they often equate with greed, while many public-policy thinker
31、s argue that the only way to fix Americas problem is to quash the private sectors role altogether and instead set up a government monopoly like Britains National Health Service.Mr. Porter strongly disagrees. He starts by acknowledging that competition, as it has been introduced to Americas health sy
32、stem, has in fact done more harm than good. But he argues that competition has been introduced piecemeal, in incoherent and counter-productive ways that lead to perverse incentives and worse outcomes:“ health-care competition is not focused on delivering value for patients,“ he says.Mr. Porter offer
33、s a mix of solutions to fix this mess, and thereby to put the sector on a genuinely competitive footing. First comes the seemingly obvious (but as yet unrealized) goal of data transparency. Second is a redirection of competition from the level of health plans, doctors, clinics and hospitals, to comp
34、etition “at the level of medical conditions, which is all but absent“. The authors argue that the right measure of “value“ for the health sector should be how well a patient with a given health condition fares over the entire cycle of treatment, and what the cost is for that entire cycle. That right
35、ly emphasizes the role of early detection and preventive care over techno-fixes, pricey pills and the other fallings of todays system.If there is a failing in this argument, it is that he sometimes strays toward naive optimism. Mr. Porter argues, for example, that his solutions are so commonsensical
36、 that private actors in the health system could forge ahead with them profitably without waiting for the government to fix its policy mistakes. That is a tempting notion, but it falls into a trap that economists call the fallacy of the $20 bill on the street. If there really were easy money on the p
37、avement, goes the argument, surely previous passers-by would have bent over and picked it up by now.In the same vein, if Mr. Porters prescriptions are so sensible that companies can make money even now in the absence of government policy changes, why in the world have they not done so already? One r
38、eason may be that they can make more money in the current sub-optimal equilibrium than in a perfectly competitive marketwhich is why government action is probably needed to sweep aside the many obstacles in the way of Mr. Porters powerful vision.（分数：10.00）(1).What seems to be the biggest problem wit
39、h Americas health care system?（分数：2.00）A.American spends more money on health care than on other services.B.Most Americans couldnt get their health insurance till their old age.C.Most American hospitals do not offer outstanding treatment to patients.D.The costs of health care are not steered towards
40、 a health direction.(2).The word “perverse“ (line 4, paragraph 2) is closest in meaning to（分数：2.00）A.harmful.B.economic.C.strong.D.reversed.(3).Mr. Porters argument seems to be based on the assumption that（分数：2.00）A.doctors do not have faith in the value of competition.B.the present health care comp
41、etition is not patient oriented.C.Britains National Health Service is a successful example.D.health competition will do more good than harm in the long run.(4).Which of the following might Mr. Porter propose to solve the problem?（分数：2.00）A.More statistics should be publicized.B.Improve a given patie
42、nts health condition.C.More advanced techno-fixes should be offered.D.Improve the entire cycle of treatment.(5).We can infer from the last two paragraphs that（分数：2.00）A.there is no easy money on the pavement for passers by to pick up.B.Mr. Porter is very likely to fall in a trap set up by the econom

44、e to AskForC. In a few minutes, the answer comes back, apparently supplied by a machine, but actually composed by a human. Using humans to process information in a machine-like way is not new: it was pioneered by the Mechanical Turk, a famed 18th-century chess-playing machine that was operated by a
45、hidden chessmaster. But while computers have since surpassed the human brain at chess, many tasks still baffle even the most powerful electronic brain.For instance, computers can find you a baseball schedule, but they cannot tell you directly if the Yankees are in town. Nor can they tell you whether
46、 sitting in the bleachers is a good idea on a first date. AskForCents can, because its answers come from people. “Whatever question you can come up with, theres a person that can provide the answeryou dont have the inflexibility of an algorithm-driven system,“ says Jesse Heitler, who developed AskFo
47、rCents. Mr. Heitler was able to do this thanks to a new software tool developed by Amazon, the online retailer, that allows computing tasks to be farmed out to people over the internet. Aptly enough, Amazons system is called Mechanical Turk.Amazons Turk is part toolkit for software developers, and p

Companies can become “requesters by setting up a separate account, tied to a bank account that will pay out fees, and then posting their H
49、ITs. Most HITs pay between one cent and $5. So far, people from more than 100 countries have performed HITs, though only those with American bank accounts can receive money for their work; others are paid in Amazon gift certificates.Mr. Heitler says he had previously tried to build a similar tool, but concluded that the
