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.
Which of the following statements is NOT true?
选项
A、Even windmill’s action depends on the sun.
B、The sun produces enormous energy for man to make use of
C、Some day man will be able to utilize 100% of the solar energy that gets to the earth.
D、The sun produces different heating effects in different places.
答案
C
解析
是非判断题。本题问下列哪种说法不是真的。把诸选项与文章内容一一对照可知:选项.A/B/D都提到了,且意思一致。唯有选项C的内容文章虽也提及但意思存有很大差别:文章中在倒数第四行说道: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,来列为直接地利用这一巨大的能源,根本没有说“将来会有那么一天,人类将能够100%利用传到地球上的太阳能"。再说,即使根据我们自己的一般常识,也可推断出要100%地利用太阳能是永远也不可能做得到的。故选C。
