单选题Scratchy throats, stuffy noses and body aches all spell misery, but being able to tel1 if the cause is a cold or flu may make a difference in how long the misery lasts. The American Lung Association (ALA) has issued new guidelines on combating colds and the flu, and one of the keys is being able to quickly tell the two apart. That"s because the prescription drugs available for the flu need to be taken soon after the illness sets in. As for colds, the sooner a person starts taking over-the-counter remedy, the sooner relief will come. The common cold and the flu are both caused by viruses. More than 200 viruses can cause cold symptoms, while the flu is caused by three viruses—flu A, B and C. There is no cure for either illness, but the flu can be prevented by the flu vaccine, which is, for most people, the best way to fight the flu, according to the ALA. But if the flu does strike, quick action can help. Although the flu and common cold have many similarities, there are some obvious signs to look for. Cold symptoms such as stuffy nose, runny nose and scratchy throat typically develop gradually, and adults and teens often do not get a fever. On the other hand, fever is one of the characteristic features of the flu for all ages. And in general, flu symptoms including fever and chills, sore throat and body aches come on suddenly and are more severe than cold symptoms. The ALA notes that it may be particularly difficult to tell when infants and preschool age children have the flu. It advises parents to call the doctor if their small children have flu-like symptoms. Both cold and flu symptoms can be eased with over-the-counter medications as well. However, children and teens with a cold or flu should not take aspirin for pain relief because of the risk of Reye syndrome, a rare but serious condition of the liver and central nervous system. There is, of course, no vaccine for the common cold. But frequent hand washing and avoiding close contact with people who have colds can reduce the likelihood of catching one.

单选题What's the world's greatest moral challenge, as judged by its capacity to inflict human tragedy? It is not, I think, global warming, whose effects—if they become as grim as predicted—will occur over many years and provide societies time to adapt. A case can be made for preventing nuclear proliferation, which threatens untold deaths and a collapse of the world economy. But the most urgent present moral challenge, I submit, is the most obvious: global poverty. The solution to being poor is getting rich. It's economic growth. We know this. The mystery is why all societies have not adopted the obvious remedies. Just recently, the 21-member Commission on Growth and Development examined the puzzle. Since 1950, the panel found, 13 economies have grown at an average annual rate of 7 percent for at least 25 years. The panel identified five common elements of success: Openness to global trade and, usually, an eagerness to attract foreign investment; political stability and "capable" governments "committed" to economic growth; high rates of saving and investment, usually at least 25 percent of national income; economic stability, keeping government budgets and inflation under control and avoiding a broad collapse in production; a willingness to "let markets allocate resources," meaning that governments didn't try to run industry. Of course, qualifications abound, still, broad lessons are clear. Globalization works. Countries don't get rich by staying isolated. Those that embrace trade and foreign investment acquire know-how and technologies, can buy advanced products abroad, and are forced to improve their competitiveness. The transmission of new ideas and products is faster than ever. There is a role for foreign aid, technical assistance and charity in relieving global poverty. But it is a small role. It can improve health, alleviate suffering from natural disasters or wars, and provide some types of skills. But it cannot single: handedly stimulate the policies and habits that foster self-sustaining growth. Japan and China have grown rapidly not because they received foreign aid but because they pursued pro-growth policies and embraced pro-growth values. The hard question is why all societies haven't adopted them. One reason is politics; some regimes are more interested in preserving their power and privileges than in promoting growth. But the larger answer, I think, is culture, as Lawrence Harrison of Tufts University argues. Traditional values, social systems or religious views are often hostile to risk-taking, wealth accumulation and economic growth. In his latest book, Harrison contends that politics can alter culture, hut it isn't easy. Globalization has moral as well as economic and political dimensions. The United States and other wealthy countries are experiencing an anti-globalization backlash. Americans and others are entitled to defend themselves from economic harm, but many of the allegations against globalization are wildly exaggerated. By making globalization an all-purpose scapegoat for economic complaints, many "progressives" are actually undermining the most powerful force for eradicating global poverty.
