问题     America is the land of the automobile. This country has only 6 percent of the world’s population out of 46 percent of the world’s cars. Right now, there are 97 million privately owned cars consuming 75 billion gallons of gasoline and traveling an estimated 1 000 billion miles a year. The figures also affirm something we know every time we refill our gasoline tank. The automobile is a very thirsty piece of technology. Of the total petroleum supply in the United States, 30 percent goes to quench (压制,解渴) that thirst. Every year for each passenger car, about 800 gallons of gasoline are consumed.
    Other aspects of our commitment to the automobile also bear mentioning here. It takes a great deal of energy to manufacture one automobile—about 150 million BTUs of energy. This is equivalent to 1 200 gallons of gasoline, enough to run a car for about 1 600 miles. We expend energy in the process of shipping cars from factories to showrooms, displaying them for sale and making replacement parts for repairs. One out of six jobs in the nation is associated with the automobile business. About two gallons of gasoline are consumed in the process of making every ten gallons that are pumped into an automobile’s gas tank.
    Building highways and parking lots has used up much of our land. It has been estimated that we have paved over 21 000 square miles of this country’s surface, most of it to accommodate (容 纳) the automobile. The automobile is also the largest contributor to our nation’s air pollution problem and a very serious one because most of its pollutants are emitted in our large metropolitan (大都市) areas. Aside from the great impact that would occur if everyone seriously practiced conservation, one should stop and think about his own casual use of the automobile. There are numerous situations where better planning and awareness could really make a difference in energy savings and dollars. Because the automobile uses the largest percentage of energy in an average American family’s energy budget and almost half of the dollars, the impetus for savings is tremendous.
The author suggests that energy savings could be realized______.

选项 A、with forceful limitation of the use of the automobile
B、with better arrangement and consciousness
C、with better educational programs and planning techniques
D、with more effective transportation of consumer goods

答案C

解析 本题是一道推断类问题。问作者表明节约能源可以通过什么手段实现。文章第三段指出,除了可能发生大的冲击之外,如果人人都认真地从事环保活动,就应该停下来考虑一下他们随便使用汽车的问题。在许多的情况下,更好的计划和更好的觉悟真的会带来节能和节省开支方面的大改观。由此我们可以推断,本题的正确答案应是C“可以通过更好地教育人们节约能源和更有效的计划技术”。
