问题 A. Where you stand while waiting to cross a road
B. Where you walk
C. Where you sit on a bus and how you travel
D. When you go to bed
E. When pollution levels rise and fall
F. When you get up

A. during rush hours
B. in spring and autumn
C. to toxic air
D. between autumn and winter
E. as exposure to nuclear radiation
F. on the downwind side

选项

答案E

解析 在题干中出现了as这个词,一般来说后面应该还会出现一个as以表示比较,从这一语法要求出发我们在六个选项中找到包含as的E项。文章第一段的第二句说,据报道,(air pollution)could be as damaging to our health as exposure to the radiation from the 1986 Ukraine nuclear power plant,disaster(空气污染对我们健康的伤害等同于暴露于1986年乌克兰核电站事故所产生的核辐射),可见E为正确选项。
