单选题The Bush administration is about to propose far-reaching new rules that would give people with disabilities greater access to tens of thousands of courtrooms, swimming pools, golf courses, stadiums, theaters, hotels and retail stores. The proposal would substantially update and rewrite federal standards for enforcement of the Americans With Disabilities Act, a landmark civil rights law passed with strong bipartisan support in 1990. The new rules would set more stringent requirements in many areas and address some issues for the first time, in an effort to meet the needs of an aging population and growing numbers of disabled war veterans. More than seven million businesses and all state and local government agencies would be affected. The proposal includes some exemptions for parts of existing buildings, but any new construction or renovations would have to comply. The new standards would affect everything from the location of light switches to the height of retail service counters, to the use of monkeys as "service animals" for people with disabilities, which would be forbidden'. The White House approved the proposal in May after a five-month review. It is scheduled to be published in the Federal Register on Tuesday, with 60 days for public comment. After considering those comments, the government would issue final rules with the force of law. Already, the proposal is stirring concern. The United States Chamber of Commerce says it would be onerous and costly, while advocates for disabled Americans say it does not go far enough. Since the disability law was signed by the first President Bush, advances in technology have made services more available to people with disabilities. But Justice Department officials said they were still receiving large numbers of complaints. In recent months, the federal government has settled lawsuits securing more seats for disabled fans at Madison Square Garden in New York and at the nation's largest college football stadium, at the University of Michigan. The Justice Department acknowledged that some of the changes would have significant costs. But over all, it said, the value of the public benefits, estimated at $ 54 billion, exceeds the expected costs of $ 23 billion. In an economic analysis of the proposed rules, the Justice Department said the need for an accessible environment was greater than ever because the Iraq war was "creating a new generation of young men and women with disabilities". John L. Wodatch, chief of the disability rights section of the Justice Department, said："Disability is inherent in the human condition. The vast majority of individuals who are fortunate enough to reach an advanced age will benefit from the proposed requirements. /

单选题关于引流管/片的拔除时间，不正确的是

单选题In most parts of the world, climate change is a worrying subject. Not so in California. At a recent gathering of green luminaries—in a film star's house, naturally, for that is how seriousness is often established in Los Angeles—the 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, California's governor 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 Stag's authoritative history 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 with 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. Schwarzenegger's transformation from screen warrior to eco-warrior was completed last year when he signed a bill imposing legally-enforceable limits on greenhouse—gas emissions—a first for America. Thanks mostly to its lack of coal and heavy industry, California is a relatively clean state. If it were a country it would be the world's eighth-biggest economy, but only its 16th-biggest polluter. Its big problem is transport—meaning, mostly, cars and trucks, which 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 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. Arizona's climate-change scholars decided to set a target of cutting the state's 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 other 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 is fully justified. It has done more than any other state—let alone the federal government—to fix America's 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 fails, it will become an excuse for inaction.
