问题 The haze of pollution mentioned in the first paragraph is a cloud ______.
One of the Price’s findings (Paragraph 2) about the particles of the air is that ______.
选项 A、they contain more pollutants than normal particles
B、they move much faster in high altitudes than in low altitudes
C、they are finer and lighter than normal particles
D、their ability to reflect light is much than stronger
答案D
解析 利用题干中出现的特征词“Prices’s findings”和核心词“particles of the air”作为答案线索，同时注意备选项中的核心词，这样发现答案相关句：Heather Price，a University of Washington doctoral student in chemistry, found(与findings呼应)that the amount of light reflected by the particles in the air was more than 550 percent greater than normal for that time of year．该划线结构的内容是“Heather Price发现空气中微粒反射的光线的数量比正常年份的这个时间多出了550%”，因此判断D(它们反射光的能力更强)是答案。
