选项 _________52 A:only B:just C:even D:then

答案 C

解析由文章标题和第一段第一句可知，这里指的应该是在地下燃烧的火焰。underground地下的；house房子，房屋；sky天空；water水。
煤在地下燃烧产生的火焰能够使地表温度升高，并且毁坏周围的植被，产生温室气体，甚至能点燃森林。even在这里表示程度的递进。only仅仅，只有；just仅仅；even甚至，更then 然后。
此处表示“有毒气体的释放”，表示气体的释放应用"release"。 paste糨糊；consumption 消费；release释放；elimination消除，根除。
地下煤的燃烧是一种全球性的灾难，令人惊奇的是却很少有人了解，这里表示的是一种惊讶。happily愉快地；surprisingly惊人地，出人意料地；traditionally传统地；fashionably时髦地。
在有阳光和氧气的情况下，产生的热量会引起自燃，可见煤产生的热量并没有消失。 disappear消失；exchange交换；regenerate再生；transfer转换，转变。
此处表示：这样的火灾在中国每年消耗的煤多达2亿吨。most大多数，大部分；some一些，某些；such这种的，这样的；many许多，很多。
in comparison表示“与……相比”，用在这里表示中国发生自燃的煤量与美国经济消耗的煤量的比较。case案件，情况；time时间，时代；comparison比较；turn转动，旋转。
空格后的analysis与空格前的先行词Stracher是所有关系，因此用whose来引导这个定语从句，并在从句中作主语。which哪一个，一般用来引导先行词为物的定语从句；who谁，常用来引导先行词为人的定语从句，并在从句中作主语；what什么，常用来引导疑问句或名词性从句。
这句话的意思是：地下的煤一旦燃烧，火焰将会持续几十年，甚至几百年。因此用连词 once。 yet然而；unless除非；once一旦；although尽管，虽然。
volume表示the amount of sth.，意思是“量，额”，用在这里表明有毒气体、温室气体以及黑色颗粒的量很大。data数据；figure数字；volume量，分量；image影像，形象。
科研小组的成员讨论的是这些火焰的影响，have impact on是常用搭配，表示对……有影响。impact影响，作用；attack袭击，攻击；identification鉴定，识别；implication含义，蕴含。
这句话表明，在地下燃烧的特质使这些火焰很难被探测到。develop开发，发展；relieve 解除，缓解；supply提供，供应；detect侦察，发现，探测。
根据后文的how much可知，这里指的是对产生的二氧化碳的量的评估。experiment实验；estimate评估；gather收集，聚集；illustrate说明，解释。
Gary Colaizzi提出的是一种控制这些火焰的方法，因此用method来表示。cause原因，动机；treatment治疗，疗法；rule规则，规定；method方法，方式。
切断氧气的供应，应该用cut off来表示。take up占据；cut off切除，切断；back up支持； run out用完，耗尽。
