问题     During the past two decades astonishing progress has been made in fighting infectious diseases in poor countries. Polio has almost been eradicated; malaria is being tamed; AIDS is slowly being brought under control. Yet almost unnoticed, another epidemic is raging across the developing world, this one man-made.
    Road crashes now kill 1.3 m people a year, more than malaria or tuberculosis. On present trends, by 2030 they will take a greater toll than the two together, and greater even than AIDS. The vast majority of victims die in poor and middle-income countries—1. 2m in 2011, compared with 99, 000 in rich ones. For every 100,000 cars in the rich world, fewer than 15 people die each year. In Ethiopia the figure is 250 times higher.
    It is tempting to see the kill as the price of development. Building roads is a highly effective way of boosting growth: the World Bank finds many projects to fund that do better than its minimum acceptable economic rate of return of 12%. In the rich world road deaths and growth went hand-in-hand for decades; the first death-by-car was in 1896 and the peak came in the 1970s.
    However, since then, restraints on drivers and investment in safety have slashed road deaths in the rich world by more than half. New York’s roads are now at their safest since records began in 1910. Sweden is still some way from its stated goal of ending road deaths altogether, but in 2013 just one Swedish child under seven died in a crash. Technology such as alcolocks, which prevent drunk-driving, and self-driving cars will make roads in the rich world safer still.
    Governments in poor countries tend to assume that they, too, must see deaths soar before they are rich enough to think about saving lives. Aid donors and development banks may conclude that a dangerous road is better than no road at all. But the experience of rich countries has shown that roads can be made safer cheaply and simply. And far from being an unaffordable luxury, safe roads make better economic sense than dangerous ones. Most crash victims are boys and working-age men. Their death or disability leaves families in poverty and deprives countries of their most economically valuable citizens. In medical bills, care, lost output and vehicle damage, the kill costs desperately poor countries as much as 10% of GDP.
According to Paragraph 2, which one is true?
选项 A、Car accidents cause more death in poor countries.
B、Car crashes mainly happen in developed countries.
C、Road crashes kill more people than any disease in the world.
D、The victims of car crashes mostly come from middle-class families.
答案A
解析 选项[A]对应第二段第二行：The vast majority of victims die in poor and middle-in—come countries…由此可见该项的表述是正确的。其中road crashes=car accidents；vast majorityof victims die=cause more death。故该项为答案。通过这个句子我们同时可以确定选项[B]“Car crashes mainly happen in developed countries．车祸主要发生在发达国家”的表述是错误的。选项[C]对应前两句：Road crashes now kill 1．3m people a year，more than malaria or tuberculo—sis．On present trends，by 2030 they will take a greater toll than the two together，and greater eventhan AIDS．文章仅仅提到“road crashes车祸”造成的伤亡超过“malaria疟疾”和“tuberculosis肺结核”，文章还指出：按照目前的趋势，到2030年甚至超过“AIDS艾滋病”，可见[C]项表述是不正确的。其中any disease太过于绝对。选项[D]中的“middle-class families中产阶级家庭”原文没有提到，而是提到了“middle-income countries中等收入国家”，故该项也是错误的。综上所述，本题答案为选项[A]。
