It was once thought that air pollution affected only the area immediately around large cities with factories and/or heavy automobile traffic. Today, we know that although these are the areas with the worst air pollution, the problem is actually worldwide. On several occasions over the past decade, a heavy cloud of air pollution has covered the entire eastern half of the United States and led to health warnings even in rural areas away from any major concentration of manufacturing and automobile traffic. In fact, the very climate of the entire earth may be affected by air pollution. Some scientists feel that the increasing concentration of carbon dioxide in the air resulting from the burning of fossil fuels (coal and oil) is creating a “greenhouse effect" - holding in heat reflected from the earth and raising the world's average temperature. If this view is correct and the world's temperature is raised only a few degrees, much of the polar ice cap will melt and cities such as New York, Boston, Miami, and New Orleans will be under water.

Another view, less widely held, is that increasing particulate (廢氣排往空中而形成的微粒、顆粒) matter in the atmosphere is blocking sunlight and lowering the earth's temperature ─ a result that would be equally disastrous. A drop of just a few degrees could create something close to new ice age and would make agriculture difficult or impossible in many of our top farming areas. At present we do not know for sure that either of these conditions will happen (though one recent government report prepared by experts in the field concluded that the greenhouse effect is very likely). Perhaps, if we are very lucky, the two tendencies will offset each other and the world's temperature will stay about the same as it is now.

As pointed out at the beginning of the passage, people used to think that air pollution ______.

    A. caused widespread damage in the countryside

    B. affected the entire eastern half of the United States

    C. had damaging effects on health

    D. existed merely in urban and industrial areas

As far as the greenhouse effect is concerned, the author ______.

    A. shares the same view with the scientists

    B. is uncertain of its occurrence

    C. rejects it as being ungrounded

    D. thinks that it will destroy the world soon

The underlined word “offset" in Para. 2 could best be replaced by______.

    A. slip into    B. make up for  C. set up   D. catch up with

This passage is mainly concerned with ______.

    A. the greenhouse effect                B. the burning of fossil fuels

    C. the potential effect of air pollution    D. the possibility of a new ice age
