单选题Children attending schools located in high-traffic zones have a 45 percent increased risk of developing asthma, even though time spent at school only accounts for about one-third of a child's waking hours, according to new research. Asthma is the most common chronic childhood illness in developed countries and has been linked to environmental factors such as traffic-related air pollution. "While residential traffic-related pollution has been associated with asthma, there has been little study of the effects of traffic exposure at school on new onset asthma," says Rob McConnell, professor of preventive medicine at USC's Keck School of Medicine. "Exposure to pollution at locations other than home, especially where children spend a large portion of their day and may engage in physical activity, appears to influence asthma risk as well." The study appears online in the journal Environmental Health Perspectives. The study drew upon data from the Children's Health Study (CHS), a longitudinal study of children in Southern California communities that was designed to investigate the chronic effects of air pollution on respiratory health. Using a cohort of 2 497 kindergarten and first grade children who were asthma-free when they entered the study, researchers examined the relationship of local traffic around schools and homes to diagnosis new onset asthma that occurred during three years of follow-up. Traffic-related pollution exposure was assessed based on a model that took into account traffic volume, distance to major roadways from home and school and local weather conditions. Regional ambient ozone, nitrogen dioxide (二氧化氮) and particulate matter were measured continuously at one central site in each of the 13 study communities. The design allowed investigators to examine the joint effects of local traffic-related pollution exposure at school and at home and of regional pollution exposure affecting the entire community. Researchers found 120 cases of new asthma. The risk associated with traffic-related pollution exposure at schools was almost as high as for residential exposure, and combined exposure accounting for time spent at home and at school had a slightly larger effect. Although children spend less time at school than at home, physical education, and other activities that take place at school may increase ventilation rates and the dose of pollutants getting into the lungs, McConnell notes. Traffic-related pollutant levels may also be higher during the morning hours when children are arriving at school. Despite a state law that prohibits school districts from building campuses within 500 feet of a freeway, many Southern California schools are located near high-traffic areas, including busy surface streets. "It's important to understand how these micro-environments where children spent a lot of their time outside of the home are impacting their health," McConnell says. "Policies that reduce exposure to high-traffic environments may help to prevent this disease. " The study was funded by grants from the National Institute of Environmental Health Sciences, the US Environmental Protection Agency, the South Coast Air Quality Management District, and the Hastings Foundation.

单选题When Ted Kennedy gazes from the windows of his office in Boston, he can see the harbor's "Golden Stairs", where all eight of his great-grandparents first set foot in America. It reminds him, he told his Senate colleagues this week, that reforming America's immigration laws is an "awesome responsibility". Mr. Kennedy is the Democrat most prominently pushing a bipartisan bill to secure the border, ease the national skills shortage and offer a path to citizenship for the estimated 12m illegal aliens already in the country. He has a steep climb ahead of him. As drafted, the bill seeks to mend America's broken immigration system in several ways. First, and before its other main provisions come into effect, it would tighten border security. It provides for 200 miles (320km) of vehicle barriers, 370 miles of fencing and 18000 new border patrol agents. It calls for an electronic identification system to ensure employers verify that all their employees are legally allowed to work. And it stiffens punishments for those who knowingly hire illegals. As soon as the bill was unveiled, it was stoned from all sides. Christans, mostly Republicans, denounced it as an "amnesty" that would encourage further waves of illegal immigration. Tom Tancredo, a Republican congressman running for president (without hope of success ) on an anti-illegal-immigration platform, demanded that all but the border-security clauses be scrapped. Even these he derided as "so limited it's almost a joke". Conservative talk-radio echoed his call. No one is seriously proposing mass deportation, but Mr. Tancredo says the illegals will all go home if the laws against hiring them are vigorously enforced. Most labor unions are skeptical, too. The AFL-CIO denounced the guest-worker program, which it said would give employers "a ready pool of labor that they can exploit to drive down wages, benefits, health and safety protections" for everyone else. Two Democratic senators tried to gut the program. One failed to abolish it entirely; another succeeded in slashing it from 400000 to 200000 people a year. Employers like the idea of more legal migrants but worry that the new system will be cumbersome. Many object to the idea that they will have to check the immigration status of all their employees. The proposed federal computer system to sort legal from illegal workers is bound to make mistakes. Even if only one employee in a hundred is falsely labelled illegal, that will cause a lot of headaches. And the points system has drawbacks, too. Employers are better placed than bureaucrats to judge which skills are in short supply. That is why the current mess has advantages—illegal immigrants nearly always go where their labor is in demand. Other groups have complaints, too. Immigrant-rights groups say that the path to citizenship would be too long and arduous and too few Hispanics would qualify. Nancy Pelosi, the Democratic speaker of the House, fretted that the new stress on skills would hurt families, adding that her party is "about families and family values". Some people worry that House Democrats will kill it to prevent Mr. Bush from enjoying a domestic success. Despite the indignation, public opinion favors the underlying principles. At least 60% of Americans want to give illegals a chance to become citizens if they work hard and behave.
