While still in its early stages, welfare reform has already been judged a great success in many states, at least UN is getting people off welfare. It's estimated that more than two million have left the roles since 1994. In the past four years, welfare in rolls in Athens country has been cut in half. But 70 percent of the people who left in the past two years took jobs that paid less than $6 an hour. The result: The Athens country poverty rate still remains at more than 30 percent — twice the national average. For advocates for the poor, that's an indication that much more needs to be done. "More people are getting jobs, but it's not making their lives any better," says Kathy Lairn, a policy analyst at the center in budget and policy priorities in Washington. Canter analysis of US census data nationwide found that between 1995 and 1996, a great percentage of single, fame-headed household were earning money on their own, but that average income for these households actually went down. But for many, the fact that poor people are able to support themselves almost as well without government aid as they did with it is in itself a huge victory. "Welfare was a poison. It was a toxin that was poisoning the family," says Rector. A welfare reform is changing the moral climate in low-income communities. It's beginning to rebuild the work ethic, which is much more important. Mr. Rector and others argued that once "the habit of dependency is cracked," then the country can make other policy changes aimed at improving living standards.

单选题When confronted with such questions, my mind goes ______, and I can hardly remember my own date of birth.

单选题The US may so far have enjoyed good luck in escaping a direct SARS hit, but officials aren't leaving anything to chance. The best hope for averting a SARS epidemic at home will be to keep SARS out at the nation's borders. Federal immigration laws authorize immigration authorities to exclude non-citizens who are determined to have a "communicable disease of public health significance". Immigration law also authorizes the President by proclamation to suspend the entry of any group of aliens whose entry he deems to be detrimental to the interests of the United States. This little-used power could be deployed to exclude all aliens from affected areas, a policy Taiwan has recently implemented. Under the Public Health Service Act, any individual(citizens included)may be quarantined at an international port of entry if they are reasonably believed to be carrying a designated communicable disease. As of an April 4 Executive Order by President Bush, SARS is now a designated disease. Thus, in tandem with airline screening, federal health authorities are carefully monitoring travelers from affected areas in Asia for SARS symptoms. With an estimated 25,000 individuals entering the country legally from Asia on a daily basis, that is a tall order. A single SARS-infected person getting through the net could bring down the border strategy. The US government might also front-end the border strategy through restrictions on travel by American citizens to affected areas. In a series of Cold War era decisions, the Supreme Court upheld international travel restrictions for national security reasons, and one can imagine the same rationale applying to a public health emergency. How practical it would be to prohibit — and police — a travel ban to countries such as China is another question. The initial SARS defense, then, hinges on effective border control. But US borders are far from under control. There are an estimated 8-9 million undocumented aliens now in the United States, a figure growing by as many as 500,000 per year. Asia is the largest contributor to undocumented immigration outside the western hemisphere, tunneling illegal aliens into the United States through elaborate smuggling networks. SARS could just as easily make serious inroads into the US through this backdoor rather than the front.

单选题A fundamental premise of a free-enterprise economic system is that all small business face difficult competition.

单选题Cars account for half the oil consumed in the U.S. , about half the urban pollution and one fourth the greenhouse gases. They take a similar toll of resources in other industrial nations and in the cities of the developing world. As vehicle use continues to increase in the coming decade, the U. S. and other countries will have to deal with these issues or else face unacceptable economic, health-related and political costs. It is unlikely that oil prices will remain at their current low level or that other nations will accept a large and growing US contribution to global climatic change. Policymakers and industry have four options: reduce vehicle use, increase the efficiency and reduce the emissions of conventional gasoline-powered vehicles, switch to less harmful fuels, or find less polluting driving systems. The last of these — in particular the introduction of vehicles powered by electricity — is ultimately the only sustainable option. The other alternatives are attractive in theory but in practice are either impractical or offer only marginal improvements. For example, reduced vehicle use could solve traffic problems and a host of social and environmental problems, but evidence from around the world suggests that it is very difficult to make people give up their cars to any significant extent. In the US, mass-transit ridership and carpooling have declined since World War II. Even in Western Europe, with fuel prices averaging more than $1 a liter(about $4 a gallon)and with easily accessible mass transit and dense populations, cars still account for 80 percent of all passenger travel. Improved energy efficiency is also appealing, but automotive fuel economy has barely made any progress in 10 years. Alternative fuels such as natural gas, burned in internal-combustion engines, could be introduced at relatively low cost, but they would lead to only marginal reductions in pollution and greenhouse emissions(especially because oil companies are already spending billions of dollars every year to develop less polluting types of gasoline).
