今年是禁止燃放爆竹的第五年,大城市里的人们似乎已经习惯了不在节日燃放烟花爆竹了。当然也许会有一些好事者想以身试法。在元旦、春节即将来临的时候,是应该给那些人再打一针镇静剂。
烟花爆竹自古以来就是中国人庆祝节日(尤其是春节)的一种重要形式,而且它也给我们出口创汇赚了不少美元。但是它给我们带来的痛苦也是不能忘记的,它使多少儿童在大意中失去了双目,它使多少国家财产在疏于防范时毁之一炬,它使多少个家庭在喜气洋洋的春节中突然接受了剧痛。
“玩火者自焚”的血泪教训使得许多中国人清醒地认识到,它带给人们昙花一现的美丽有时候会变成一种罪恶。北京是最先举起“禁放”大旗的城市。近年来,这个中国最美丽的城市之一已经被市民的燃煤、建筑工地的粉尘、猛增的汽车尾气污染得让人透不过气;空气质量连续几周达4级,已经不是偶然之事。北京人发出了倡导绿色革命的口号,禁放烟花理所当然是其中的一项。

文章指出,北京人应努力做到:

A.少买汽车
B.彻底禁放烟花爆竹
C.缩小建筑工地
D.禁止燃煤

答案

参考答案:B

单项选择题

Michael Porter, who has made his name throughout the business community by advocating his theories of competitive advantages, is now swimming into even more shark-infested waters, arguing that competition can save even America’s 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 claim, given the horrible state of America’s 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-wrenching 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, uneven 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 thinkers argue that the only way to fix America’s problem is to quash the private sector’s role altogether and instead set up a government monopoly like Britain’s National Health Service.

Mr. Porter ply disagrees. He starts by acknowledging that competition, as it has been introduced to America’s health system, 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 offers 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 competition "at the level of medical conditions, which is all but absent". The authors argue that the right measure of "value" for the health of treatment, and what the cost is for that entire cycle. That rightly emphasizes the role of early detection and preventive care over techno-fixes, pricey pills and the other failings of today’s 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 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 pavement, goes the argument, surely previous passers-by would have bent over and picked it up by now.

In the same vein, if Mr. Porter’s 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 reason may be that they can make more money in the current sub- optimal equilibrium than in a perfectly competitive market--which is why government action is probably needed to sweep aside the many obstacles in the way of Mr. Porter’s powerful vision.

Which of the following might Mr. Porter propose to solve the problem()

A. More statistics should be publicized

B. Improve a given patient’s health condition

C. More advanced techno-fixes should be offered

D. Improve the entire cycle of treatment
