1、全國職稱英語考試衛(wèi)生類 C 級(jí)課堂筆記概括 大意第六講 2答案及解析：1 文章標(biāo)題分析：Soot 煤灰 and Snow ： a HotCombination根據(jù)標(biāo)題內(nèi)容可以判斷該文章與自然環(huán)境環(huán)境污染有關(guān)。2被選項(xiàng)分析：A Soots Role in Changes in the Climate and theAtmosphereB Observations of Warming in the Northern HemisphereC Explanation of Increased Warming Effect Caused by SootC Effect to Reduce Snow A

2、lbedo反照率E Ways to Reduce Soot EmissionF Greenhouse Gases as the Main Factor of G1obal Warming 分析：被選項(xiàng)中都涉及到了文章標(biāo)題所揭示的核心詞，劃線結(jié)構(gòu) 是小標(biāo)題中的核心結(jié)構(gòu)，也是可以用作答案線索的結(jié)構(gòu)。直接解題：A Soots Role in Changes in the Climate and the AtmosphereB Observations of Warming in the Northern HemisphereC Explanation of Increased Warming Eff

3、ect Caused by SootC Effect to Reduce Snow Albedo反照率E Ways to Reduce Soot EmissionF Greenhouse Gases as the Main Factor of G1obal Warming1 Paragraph 3 _.Soot in areas with snow and ice may play an important role in climate change Also ，if snow and ice- covered areas begin melting ，the warming effect

4、increases， as the soot becomesmore concentrated on the snow surface This provides apositive feedback, as glaciers and ice sheets melt， they tend toget even dirtier, said Dr James Hansen ，a researcher at NASAs Goddard Institute for Space Studies New York 1C 分析：段首句的大意和用詞似乎在暗示 A 是答案。但是 在下文中沒有具體提到 soot

5、是如何改變氣候的排除 A 。段落中 soot 出現(xiàn)了兩次，因此重點(diǎn)注意包含 soot的被選項(xiàng)：C和E。段落中沒 有提到有關(guān)煤灰散發(fā)的問題，所以排除E,選擇C。提示：在借助段首句內(nèi)容的時(shí)候判斷答案的時(shí)候還應(yīng)該掃視一下 全文A Soots Role in Changes in the Climate and theAtmosphereB Observations of Warming in the Northern HemisphereC Effect to Reduce Snow Albedo反照率E Ways to Reduce Soot EmissionF Greenhouse Gases

6、as the Main Factor of G1obal Warming2 Paragraph4 _ Hansen found soots effect on snow albedo solar energy reflected back to space ， which may be contributing to trends toward early springs in the Northern Hemisphere， such asthinning Arctic sea ice ，melting glaciers and permafrostSootalso is believed

7、to play a role in changes in the atmosphere above the oceans and land 2A 分析：因?yàn)槎温渲?soot 出現(xiàn)了兩次，因此重點(diǎn)注意包含 soot的被選項(xiàng)：A和E,同樣段落中沒有提到有關(guān)煤灰散發(fā)的問題, 所以判斷 A 是答案段落最后一句觀點(diǎn)句的含義與 A 一致提示： 避重就輕法 - 段首句復(fù)雜那么看段未句。反照率B Observations of Warming in the Northern HemisphereC Effect to Reduce Snow AlbedoE Ways to Reduce Soot Emissi

8、onF Greenhouse Gases as the Main Factor of G1obal Warming3 Paragraph 6 _.Hansen cautioned ， although the role of soot in altering global climate is substantial ， it does not alter the fact that greenhouse gases are the primary cause of climate warming during the past century Such gases are expected

9、to be the largest climate forcing for the rest of this century 3 F。 分析：因?yàn)槎温渲?gas 出現(xiàn)了兩次，因此重點(diǎn)注意包含 gas的被選項(xiàng)：F。而F中的內(nèi)容正好與段首句中的核心結(jié)構(gòu)it doesnot alter the fact that greenhouse gases are the primary cause of climate warming during the past century它沒有改變 溫室效應(yīng)是在過去的世紀(jì)中造成氣候變暖的主要原因 這個(gè)事實(shí)一致。B Observations of Warming i
