TPO23-1 Urban Climates
Paragraph 3
The burning of fuel, such as by cars, is not the only source of this increased heat. Two other factors contribute to the higher overall temperature in cities. The first is the heat capacity of the materials that constitute the city, which is typically dominated by concrete and asphalt. During the day, heat from the Sun can be conducted into these materials and stored—to be released at night. But in the countryside materials have a significantly lower heat capacity because a vegetative blanket prevents heat from easily flowing into and out of the ground. The second factor is that radiant heat coming into the city from the Sun is trapped in two ways: (1) by a continuing series of reflection among the numerous vertical surfaces that buildings present and (2) by the dust dome, the cloudlike layer of polluted air that most cities produce. Shortwave radiation from the Sun passes through the pollution dome more easily than outgoing longwave radiation does; the latter is absorbed by the gaseous pollutants of the dome and reradiated back to the urban surface.
4.According to paragraph 3, each of the following contributes to making urban areas warmer than the surrounding countryside EXCEPT
A. the fuel burned by motor vehicles
B. the capacity to store heat of the materials used in building a city
C. the easy flow of heat into the ground in city areas covered by vegetation
D. the repeated reflection of solar radiation back and forth among buildings
解析：discern辨别，察觉，所以正确答案是identity。从单词本身看，dis有分开之意，cern有确定，弄清之意，想想concern，所以两者合在一起必然有区分、辨别之意。原文说Australian rock art的stylic organization究竟是什么，是否有可能怎么样一个sequence或者一种pattern，所以答案是C。repeat和apply不沾边，indicate有暗示，指明之意，而原文没有，不选
[3]燃料的燃烧，比如汽车燃料，并不是这种热量增加的唯一来源。另外两个因素导致了城市较高的整体温度。第一个是建造城市的材料的热容，主要典型材料是沥青和混凝土。白天，来自太阳的热量传入到这些物质当中并储存起来，在晚上被释放。但是在乡村储存能量的物质热容更低，因为植被会阻止热量轻易流入和流出地面。第二个因素是从太阳到城市的辐射热以两种形式被拦截了：(1)通过大量建筑的垂直表面的不断反射(2)通过尘埃，即大多数城市中受污染空气组成的云状物质。来自太阳的短波辐射比长波辐射要更容易穿过污染层;后者被这层物质中的气体污染物所吸收，然后重新辐射到城市的表层。
以上就是托福阅读TPO23-1中的否定事实信息题及其解析，大家可以在备考的时候参考复习，希望能够帮助大家的考前准备。最后前程百利祝大家都能取得理想的托福考试成绩。
