These large scale ________（51） blazes ( 火焰 ) cause the ground temperature to heat up and kill surrounding vegetation, produce greenhouse gases and can________（52）ignite ( 点燃) forest fires, a group of scientists told the annual meeting of the American Association for the Advancement of Science in Denver. The resulting ________（53 ）of poisonous elements like mercury can also pollute local water sources and soils, they warned.     "Coal fires are a global disaster," said Associate Professor Glenn Stracher of East Georgia Collage in Swainsboro, USA. But ________（54）few people know about them.     Coal can heat up on its own, and eventually catch fire and burn, if there is a continuous oxygen supply. The heat produced is not caused to________（55）  and under the right binations of sunlight and oxygen, can trigger spontaneous ( 自发的 ) catching fire and burning. This can occur underground, in coal stockpiles, abandoned mines or even as coal is transported. ________（56） fires in China consume up to 200 million tons of coal per year, delegates were told. In ________（57）, the U.S. economy consumes about one billion tons of coal annually, said Stracher, ________（58）analysis of the likely impact of coal fires has been accepted for publication in the International Joomal of Acoal Ecology.________（59） underway, coal fires can burn for decades, even centuries. In the process, they release large ________（60）of greenhouse gases, poisonous fumes and black particles into the atmosphere.     The members of the panel discussed the ________（61）these fires may be having on global and regional climate change, and agreed that the underground nature of the fires makes them difficult to________（62）    Ultimately, the remote sensing and other techniques should allow scientists to ________（63） how much carbon dioxide these fires are emitting ( 释放 ). One suggested ________（64）of containing the fires was presented by Gary Colaizzi, of the engineering firm Goodson, which has developed a heat-resistant grout ( 灌浆 ), which is designed to be pumped into the coal fire to ________（65）the oxygen supply.1.[不定向选择题]________A.data B.volume C.figure D.image 2.[不定向选择题]________A.which B.who C.whose D.what
