问题 The author’s main purpose in writing the article is to warn of______.
The only way to stop the spread of aerosols in the atmosphere, according to Dr Rasool and Dr Schneider, is to use______.

选项 A、fossil fuels
B、electric power
C、nuclear energy
D、coal power

答案C

解析 利用“Dr Rasoo1 and Dr Schneider”作为答案线索词,于是在第6段直接找到答案相关句The only bright spot in this gloomy forecast lies in the hope expressed by Dr Rasoo1 and Dr Schneider that nuclear powder may replace fossil fuels in time to prevent the aerosol content of atmosphere from becoming critical,该句说“Dr Rasoo1 and Dr Schneider认为这个悲观预测中的惟一亮点就是希望核能量能及时地替代化石燃料以防止大气层中的悬浮颗粒含量变得更加危险。”因此判断答案是c。
