The members of the panel discussed the impact these fires may be having on global and regional climate change, and agreed that the underground nature of the fires makes them difficult to protect. One of the members of the panel, Assistant Professor Paul Van Dijk of the International Institute for Geo-Information Science and Earth Observation in the Netherlands, has been working with the Chinese government to detect and monitor fires in the northern regions of the country.
Ultimately, the remote sensing and other techniques should allow scientists to estimate how much carbon dioxide theses fires are emitting. One suggested method of containing the fires was presented by Cary Colaozzi, of the engineering firm Goodson, which has developed a heat-resistant grout (a thin mortar used to fill cracks and crevices,) which is designed to be pumped into the coal fire to cut off the oxygen supply.
1。 According to the first paragraph, one of the warnings given by the scientists is that
A. underground fires loom large in the forests.
B. coal burning deep underground is found in China
C. poisonous elements released by the underground fires can pollute water sources.
D. arsenic and mercury are the most poisonous elements to water sources
2 According to the third paragraph, what will happen when the underground heat does not disappear?
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
3 What did Stracher analyze in his article published in the International Journal of Coal Ecology?
A. annual consumption of coal in U.S.
B. annual consumption of coal in China
C. how long coal fires has lasted in the northern region of China
