问题 Three Yale University professors agreed in a panel discussion tonight that the automobile was what one of them called "Public Health Enemy No. 1 in this country. ’ Besides polluting the air and congesting the cities, cars are involved in more than half the disabling accidents, and they contribute to heart disease "because we don’t walk anywhere anymore," said Dr. H. Richard Weinerman, professor of medicine and public health.
    Relating many of these manmade hazards to the automobile, Arthur W. Galston, a professor of biology, said it was possible to make a keroseneburning turbine car that would "lessen smog by a very large factor." But he expressed doubt that Americans were willing to give up moving about the countryside at 90 miles an hour in a large vehicle. "America seems wedded to the motor car—every family has to have at least two, and one has to be a convertible with 300 horsepower," Professor Galston continued. "Is this the way of life that we choose because we cherish these values?"
    For Professor Sears, part of the blame lies with "a society that regards profit as a supreme value, under the illusion that anything that’s technically possible is, therefore, ethically justified." Professor Seam also called the country’s dependence on its modem automobiles "lousy economics" because of the large horsepower used simply "moving one individual to work". But he conceded that Americans have painted themselves into a comer by allowing the national economy to become so reliant on the automobile industry.
    The solution, Dr. Weinerman said, "is not to find a less dangerous fuel but a different system of innercity transportation. Because of the increasing use of cars, public transportation has been allowed to wither and degenerate, so that if you can’t walk to where you want to go, you have to have a car in most cities," he assorted. This in turn, Dr. Weinerman contended, is responsible for the "arteriosclerosis’ of public roads, for the blight of the inner city and for the middleclass movement to the suburbs.
The main idea of the passage is that ______.
选项 A、Americans are too attached to their cars
B、public transportation in America is welldeveloped
C、American cars are too fast
D、automobiles endanger health
答案D
解析 主旨大意题。见文章的第一句话。是全文的主题句。指明了健康的头号敌人就是汽车，并且，在后面的段落中，指出了其原因及解决办法，故选项D是正确的。
