能的来源

成因说明:能的来源-Sources of Energy

【内容提示】

就下面关于几种能的来源提示写一篇英语文章:

①所有的能都间接或直接地来源于太阳。太阳能两形式:一种是热射线,一种是光射线。以月亮的光为例说明。

②电能以间接的方式来源于太阳,例如它可来自从山腰流下的水的力量。这水就是雨,而雨是由太阳的热蒸发而来的。

③煤里的光能和热能也是间接来自太阳。煤是由树木和其他植物经过千百万年前的岩石挤压形成的,而树木和植物是由于太阳的帮助成长起来的。

④我们用来驱动汽车引擎的能来自汽油。汽油也是由太阳的间接帮助生成的。千百万年前死了的动植物压在岩石下,生成石油,汽油是从石油中提炼出来的。

⑤我们可以说,几乎所有的能都来自太阳;没有太阳地球上就不可能有生命。

Th light and hat nrgy from coal also coms from th sun in a roundabout way. Coal was mad by th rocks prssing on trs and plants which did millions of yars ago. Thos trs and plants grw with th aid of sunlight, from which thy mad carbohydrats⑤, in this way changing th sun's nrgy into chmical nrgy. Whn w burn coal, som of this nrgy is st fr.
