问题 According to the first paragraph, one of the warnings given by the scientists is that______.
According to the third paragraph, what will happen when the underground heat does not disappear?

选项 A、Coal heats up on its own and catches fire and burns.
B、The underground oxygen will be used up.
C、Poisonous fumes and greenhouse gases will be accumulated underground.
D、There will be an increases of abandoned mines.

答案A

解析 利用题干中的核心词(新信息词)underground heat作为答案线索,注意备选项中出现的核心词/特征词(A:coal heats up;B:underground oxygen;C:poisonous fumes and greenhouse gases;D: abandoned mines),这样发现答案相关句:Coal can heat up on its own, and eventually catch fire and burn(与 A有关系),if there is a continuous oxygen supply. (该句没有提到地下氧气被用光,所以排除B)The heat produced is not caused to disappear and under the right combinations of sunlight and oxygen, can trigger spontaneous(自然产生的)catching fire and burning. (该句说“所产生的热没有消失,在太阳光和氧气的作用下,能诱发自然。”显然这与A的内容一致。)This can occur underground,in coal stockoiles, abandoned mines or even as coal is transported.(该句没有提到被废弃的矿井的增加,所以排除D)。
