问题 According to the first paragraph, one of the warnings given by the scientists is that______.
According to the fifth paragraph, what is the suggested method to control underground fires?
选项 A、Using remote sensing techniques.
B、Controlling the release of carbon dioxide.
C、Making the soil heat resistant.
D、Cutting off the oxygen supply.
答案D
解析 该题可以借助常识(没有氧气火就不能燃烧)直接判断D是答案，也可以借助原文，  题干中说“suggested method(被建议的方法)”，所以考虑利用suggested method作为答案线索，寻找答案相关句：One suggested method of containing the fires was presented by Cary Colaozzi, of the engineering firm Goodson，which has developed a heat-resistant grout(水泥浆)(a thin mortar(灰泥)used to fill cracks and crevices (裂缝)which is designde to be pumped into the coal fire to cut off the oxygen supply.该划线结构的含义表明“使用隔热水泥浆的最终目的是为了切断氧气的供应”，因此判断D是答案。
