On cold days in Delhi, the poor light bonfires (篝火) of tyres, trees and rags whose fumes mix with the exhaust from the city’s 2 million vehicles to form a thick smog. On most days in Mexico City, a blanket of pollution cuts off views of the surrounding mountains. On one famous occasion it got so bad that birds fell dead out of the sky on to the Zocalo, the city’s main square. Throughout the developing world, smogs in many big cities are getting worse as more people use cars and more manufacturing firms are belching out (喷出) pollution. Congestion is on the rise, too- according to one estimate, a car in Bangkok now spends the equivalent of 40 days a year stuck in traffic. The air in Asia’s cities, like the water in its rivers, is particularly unhealthy, containing levels of dust and smoke several times higher than in the rich countries’ cities.
Environmentalists in the developed world also worry about air pollution in poorer countries, not just out of the goodness of their hearts but because they fear it may affect their own backyard. Carbon-dioxide emissions, thought to be the cause of global warming, are growing particularly fast in developing countries. So are emissions of sulphur dioxide, blamed for acid rain, which sometimes falls hundreds of miles from the source of the pollution.
But the harm that air pollution causes in the developing countries themselves is much more serious and immediate. The biggest concern are indoor air pollution, lead emissions and small particles. Indoor pollution in poor countries is not much talked about, but it is often as damaging to health as smoking cigarettes. Around a third of all energy consumed in developing countries comes from wood, crop residues and dung, which are often burnt in poorly designed stoves within ill-ventilated (通风很差的) huts. Studies of women in India and Nepal exposed to smoke from such fuels show that their death rates from chronic respiratory disease are similar to those of heavy smokers.
Lead has long been known to be dangerous in large doses. But only since the 1970s have scientists been aware that relatively small quantities of lead in the bloodstream can be harmful to humans. In particular, many studies show a correlation between levels of lead in children’s blood and lower IQ scores, hearing loss and hyperactivity (活动过度).
But the kind of air pollution thought to cause the most damage to human health in developing countries is that from small particles. Caused by vehicle exhausts, coal-burning smoke from factories and dust stirred up by vehicles, these particles easily find their way into people’s lungs. Studies the world over have shown a strong positive correlation between small particles in the air and death rates.
Environmentalists in the developed countries also worry about air pollution in poorer countries because______.
选项
A、they are very kind-hearted and care much about the people there
B、they are afraid that more people will immigrate into their countries
C、they know that governments there are not taking effective measures to deal with the problem
D、they fear that the pollution there may cause harm to their own countries
答案
D
解析
细节题。发达国家的环境学家也担心贫穷国家的环境问题,不只是出于他们心地善良,而是由于他们害怕自己的后院也会受到影响,也就是说他们害怕发展中国家的空气污染问题会引起全球变暖和酸雨,而这自然会影响到他们自己的国家。因此D是正确答案。
