The energy which the sun radiates goes in every direction , and only a minute part of it falls on the earth. Even so, it represents power of about 5 , 000, 000 horsepower(马力)per square mile per day: the sun gives us as much energy every minute as mankind utilizes in a year. At present, we use this energy indirectly, and it is our final source of power. Coal represents the chemical action of the sun on green plants thousands of years ago. Waterpower results from the rain formed by vapor which comes from the evaporation of water under the sunshine. Even windmills operate because of air currents set in motion by the different heating effects of the sun in different places. Some day, through chemistry or some type of solar engine, we shall harness this great source of energy more directly. Already a scientist has worked out an engine, surprisingly efficient, in which the sun’s rays are concentrated through mirrors on a tube of water to create steam.
In order to support this argument, the writer gives the example that______.
选项
A、a machine using solar energy efficiently has already been developed
B、the sun is our final source of power
C、man uses only a tiny part of the sun’s energy
D、the part of the sun’s energy we use is used indirectly
答案
A
解析
倒过来考的例证考题。一般例证考题都是问本文提到了……是为了证明……。本文反其道而行之,问为了证明这个论点(即:将来会有那么一天,我们会通过化学方法或者某种太阳能发动机来更为直接地利用这一巨大的能源)作者给了个……的例证。依据文章倒数第二句:“科学家已经设计出了一台发动机,效率令人吃惊的高。”可知,选A对。做这种题的方法和做例证考题的寻找信息的方向相反,例证考题回头看,向上文去找答案,而这种考题则要向下文去找答案。
