  Urban Climate

  城市气候

  P1: The city is an extraordinary processor of mass and energy and has its own metabolism. A daily input of water, food, and energy of various kinds is matched by an output of sewage, solid waste, air pollutants, energy, and materials that have been transformed in some way. The quantities involved are enormous. Many aspects of this energy use affect the atmosphere of a city, particularly in the production of heat.

  extraordinary adj. 非凡的

  metabolism n. 新陈代谢

  enormous adj. 巨大的

  aspect n. 方面

  atmosphere n. 大气层

  A daily input of water, food, and energy of various kinds is matched by an output of sewage, solid waste, air pollutants, energy, and materials[that have been transformed in some way].

  每天水、食物和各种各样的能量的输入与相应的输出的废水、废气、固体垃圾、废能和[某种程度上已经变形的]材料的量得以匹配。

  P2: In winter the heat produced by a city can equal or surpass the amount of heat available from the Sun. All the heat that warms a building eventually transfers to the surrounding air, a process that is quickest where houses are poorly insulated. But an automobile produces enough heat to warm an average house in winter, and if a house were perfectly insulated, one adult could also produce more than enough heat to warm it. Therefore, even without any industrial production of heat, an urban area tends to be warmer than the countryside that surrounds it.

  surpass v. 超过,优于

  warm v. 加热

  insulate v. 使隔热,使绝缘

  All the heat [that warms a building] eventually transfers to the surrounding air, a process [that is quickest] [where houses are poorly insulated].

  所有[用来供暖的]热量最后都扩散至周围的空气中,这个过程在[那些隔热效果差的房屋里][进行得最快]。
