易错题解析：
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.
6. How is paragraph 3 organized?
○ It describes two factors that contribute to the increased heat of cities and then provides two causes for the second factor.
○ It describes two causes discovered in an early analysis of the increased heat of cities.
○ It describes two factors that contribute to the increased heat of cities and two other factors that work against it.
○ It describes two well-established causes of the increased heat of cities and other two whose roles are less well understood.
题型：结构题目。答案是(A)
解析：这是一个特殊的题型。是问第三自然段内容的安排。讲得是城市热量比较高的原因。首先开始就说燃料的燃烧不是唯一原因，接着谈及了另外两个原因。由first找到第一个原因是组成城市的主要典型物质是沥青和混凝土。由second找到第二个因素是太阳辐射进城市的热能有两种传递方式然后又分别阐释(1)通过大量建筑的垂直表面的一系列折射来传递;(2)通过由大多数城市中受污染空气组成的云状物质来传递。所以正确答案是A。It describes two factors that contribute to the increased heat of cities and then provides two causes for the second factor.
易错选项：(B)。
Paragraph 4: Cities, then, are warmer than the surrounding rural areas, and together they produce a phenomenon known as the urban heat island. Heat islands develop best under particular conditions associated with light winds, but they can form almost any time. ■The precise configuration of a heat island depends on several factors. ■For example, the wind can make a heat island stretch in the direction it blows. ■When a heat island is well developed, variations can be extreme; in winter, busy streets in cities can be 1.7℃ warmer than the side streets. ■Areas near traffic lights can be similarly warmer than the areas between them because of the effect of cars standing in traffic instead of moving.
13. Look at the four squares [■] that indicate where the following sentence could be added to the passage.
Another possibility is for the heat island to be stretched along the course of major rivers, since large waterways typically have a warming effect on the air directly above them.
Where would the sentence best fit?
题型：句子插入题。答案是(C)
解析：要插入句子中的关键词为Another possibility is for the heat island to be stretched along the course of major rivers, since large waterways typically have a warming effect on the air directly above them. 所以回归原文寻找与关键词有联系的句子，发现■For example, the wind can make a heat island stretch in the direction it blows. 所以是放在它后面，该句本身是一种可能性，而被插入的句子则提供了另外一种可能性。而且意思也非常合适。
