All the useful energy at the surface of the earth comes from the activity of the sun. The sun heats and feeds creatures and mankind. Each year it provides men with two hundred million tons of grain and nearly ten million tons of wood.
Coal, oil, natural gas, and all other fuels are stored energy from the sun. Some was collected by this season’s plants as carbon compounds. Some was stored by plants and trees ages ago. Even waterpower derives from the sun. Water turned into vapor by the sun falls as rain. It courses down the mountains and is converted to electric power. Light transmits only the energy that comes from the sun’s outer layer, and much of this energy that is directed towards the earth never arrives. About nine tenths of it is absorbed by the atmosphere of the earth. In fact, the earth itself gets only one half millionth of the sun’s entire output of radiant energy.
选项
A、gasoline
B、natural gas
C、atomic power
D、animal fat
答案
C
解析
本题考查的是考生对细节的把握。答案在第二段首句:"煤、油、天然气以及其他各种燃料都是来自于太阳中储存的能量"。选项中gasoline(汽油)和animal fat(动物脂肪)都属于oil(油);而natural gas(天然气)在原文中已经列举出;只有C项(原子能)没有在文中提到。
