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 extrene; 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. The maximum differences in temperature between neighboring urban and rural environments is called the heat-island in tensity for that region. In general, the larger the city, the greater its heat-island intensity. The actual level of intensity depends on such factors as the physical layout, population density, and productive activities of a metropoils.


8. According to paragraph 4, what can explain the substantial differences in temperature between one area and other within a well-developed heat island?
A. The overall size of the heat island that includes the two reasons
B. The intensify of the heat island that includes the two areas
C. Differences between the two areas in the general level of activity, including traffic
D. Differences between the two areas in the insulation materials used in construction

答案选的是C， 想知道为什么不能选B？B错在哪呢？

谢谢！

我觉得C一目了然啊....C才是对heat island的explain啊....真没发现B哪里对了...

话说，童鞋你是不是题目没看清啊....题干问的是one area and other within a well-developed heat island.....

没问你urban和rural的difference....文章中的对应应该是前面那句...

我觉得不是楼主定位错了呢，是因为B的意思不是heat intensity 是 intensity of heat island 不太一样呢
