单选题 For the past few weeks, we have been discussing national energy conservation alternatives for the future. Today I'm going to talk about what one community is presently doing to conserve (保存) energy. The people of Davis, California, have succeeded in cutting their energy consumption by 1/3 since 1973. The first energy saving action that was taken in the early 70's was the legislation (立法) of street building codes. All new houses in Davis must have the proper insulation (绝缘) so that heat will not escape unnecessarily during the winter. New houses must also face north or south, so that they will not be overheated by the sun in summer. The law has definitely had an effect. Since 1976, there has been a 50 percent saving in the amount of natural gas and electricity used in healing and air conditioning. There are other energy saving features about Davis. Buses partially supported by the city transport university students throughout the area. There are 24 miles of bicycle paths, and today there are twice as many bicycles as cars in the city. By reducing the available parking space, the city council has succeeded in reducing the number of cars in the city every day. Another benefit of the reduced parking is the greater number of small cars. People are saving gas because they are choosing not to drive, or because they are driving fuel-economic car. Davis, California has become an energy saving model for other cities. Time is up for today. Next week, we'll return to our regular topic of national energy alternatives.

单选题There was one thought that air pollution affected only the area immediately around large cities with factories and heavy automobile traffic. At present, we realize that although these are the areas with the worst air pollution, the problem is literally worldwide. On several occasions over the past decade, a heavy cloud of air pollution has covered the east of the United States and brought health warnings in rural areas away from any major concentration of manufacturing and automobile traffic. In fact, the very climate of the entire earth may be infected by air pollution. Some scientists consider 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"—conserving 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 in water. Another view, less widely held, is that increasing particular 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 a new ice age, and would make agriculture difficult or impossible in many of our top farming areas. Today we do not know for sure that either of these conditions will happen (though one recent government report drafted by experts in the field concluded that the greenhouse effect is very possible). Perhaps, if we are lucky enough, the two tendencies wilt offset each other and the world"s temperature will stay about the same as it is now. Driven by economic profits, people neglect the damage on our environment caused by the "advanced civilization". Maybe the air pollution is the price the human beings have to pay for their development. But is it really worthwhile?
