1．People used to think that air pollution________.A．caused widespread damage in the countrysideB．affected the entire eastern half of the United StatesC．had a very bad effect on healthD．existed merely in urban and industrial areas解析：选D 细节理解题。

根据文章第一段第一句可知，人们过去认为空气污染只存在于工厂林立的工业区和交通拥挤的大城市当中。

故选D。

2．As to the greenhouse effect, the author________.A．shares the same view with the scientistsB．is uncertain of its occurrenceC．rejects it as being ungroundedD．thinks that it will destroy the world soon解析：选B 推理判断题。

根据第一段最后一句中的“If this view is correct and ...”可知，作者并不确定这种观点(来自化石燃料燃烧的二氧化碳会导致温室效应，使全球变暖)是否正确。

故选B。

3．The underlined word “offset” in the second paragraph could be replaced by “________”．A．counteract B．break fromC．get along D．communicate解析：选A 词义猜测题。

根据画线词所在的句子及其前一句可知，我们不知道这两种可能情况(全球变暖和全球变冷)中的哪种会发生，如果我们足够幸运的话，这两种现象会相互抵消中和，温度依然会保持不变。

因此，offset应为“补偿；抵消”之意，故选A。
