Such fires in China consume up to 200 million tones of coal per year, delegates were told. In comparison, the U.S. economy consumes about one billion tons of coal annually, said Stracher, whose analysis of the likely impact of coal fires has been accepted for publication in the International Journal of coal ecology, once underway, coal fires can burn for decades, even centuries. 該句內(nèi)容直接揭示D是答案。而前文中也有相關(guān)的內(nèi)容：
“Coal fires are a global catastrophe,” said Associate Professor Glenn Stracher of East Georgia College in Swainsboro, USA. But surprisingly few people know about them.該句也暗示“煤引起的大火會(huì)產(chǎn)生巨大的影響”，因此也判斷D是答案。
有效思路特點(diǎn)；抓住文章中心（文章開(kāi)頭一直在說(shuō)地下煤的燃燒所帶來(lái)的環(huán)境影響）

A. he was one of the scientists who have warned against the threats of underground fires
B. he has detected and monitored underground fires in Netherlands
C. he has worked with the Chinese government on the underground fires issue.

4．B．分析：利用題干中出現(xiàn)的特征詞Paul Van Dijk作為答案線索，同時(shí)注意利用被選項(xiàng)中的核心詞（黑體部分內(nèi)容）作為答案線索，發(fā)現(xiàn)B和D在用詞上有關(guān)系，重點(diǎn)注意，這樣發(fā)現(xiàn)答案相關(guān)句：
前文相關(guān)內(nèi)容：a panel of scientists told the annual meeting of the American Association for the Advancement of Science in Denver.
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（劃線結(jié)構(gòu)揭示A的說(shuō)法正確）, Assistant Professor Paul Van Dijk of the International Institute for Geo-Information Science and Earth Observation in the Netherlands（劃線結(jié)構(gòu)揭示D的說(shuō)法正確）, has been working with the Chinese government to detect and monitor fires in the northern regions of the country（該句揭示B不正確： 原文說(shuō)Paul Van Dijk 研究的是中國(guó)的地下火）.
