Used to Be Much Greener Once Experienced Warm Periods Cities Warned of Coming Disasters Greenland, A Perfect Destination【答案】 （1）C（2）B（3）D（4）A 【解析】【分析】本文是一篇說明文，介紹了在古代沉積物中發(fā)現(xiàn)的一條微小線索揭開了格陵蘭島過去和未來氣候的大秘密。就在廣闊的格陵蘭冰原的西北邊緣，研究人員發(fā)現(xiàn)了在最后一個(gè)冰河時(shí)代幸存下來的湖泥。現(xiàn)在研究人員認(rèn)為，格陵蘭北部的冰蓋經(jīng)歷了比之前認(rèn)為的更強(qiáng)烈的變暖。 （1）考查推理判斷。根據(jù)第一段中的“The mud, and remains of mon flies in it, record two interglacial periods（間冰期）in northwest Greenland.”在格陵蘭島西北部，泥漿和常見蒼蠅的殘骸記錄了兩次間冰期；以及第二段中的“Although researchers have long known these two periods—the early Holocene and Last Interglacial—experienced warming in the Arctic, the mix of fly species shows that Greenland was even warmer than previously thought. ”盡管研究人員很早就知道這兩個(gè)時(shí)期——全新世早期和最后一次間冰期——在北極經(jīng)歷了變暖，但混合的蠅類表明格陵蘭島甚至比之前認(rèn)為的還要熱?？芍?，在前兩段中提到蒼蠅的殘骸是為了證明格陵蘭島的溫度比之前認(rèn)為的要高得多。故選C。 （2）考查細(xì)節(jié)理解。根據(jù)第三段中的“This new information could help researchers better measure Greenland39。s sensitivity to warming, by testing and improving models of climate and ice sheet behaviour. ”可知，這些新信息可以幫助研究人員更好地測量格陵蘭島對氣候變暖的敏感性。故選B。 （3）考查細(xì)節(jié)理解。根據(jù)第三段中的“After all, Greenland covers 80 per cent of the Arctic country and holds enough ice to equal 20 feet of global sea level. ‘Northwest Greenland might feel really remote, but what happens to that ice sheet is going to matter to everyone in every coastal city around the world,’” 可知，格陵蘭島覆蓋了這個(gè)北極國家的80%，擁有相當(dāng)于全球海平面20英尺的冰?！案窳晏m西北部可能真的感覺很遙遠(yuǎn)，但冰蓋的變化將關(guān)系到世界上每個(gè)沿海城市的每個(gè)人?！惫蔬xD。 （4）考查主旨大意。本文通過最新的發(fā)現(xiàn)——最后一個(gè)冰河時(shí)代幸存下來的湖泥及湖泥中的蒼蠅殘骸及其相關(guān)研究說明格陵蘭島之前可能更暖和。因此，本文的最佳標(biāo)題應(yīng)為“格陵蘭島曾經(jīng)更加綠色”。故選A。 【點(diǎn)評】本題考點(diǎn)涉及細(xì)節(jié)理解，推理判斷和主旨大意三個(gè)題型的考查，是一篇科研類閱讀，考生需要準(zhǔn)確捕捉細(xì)節(jié)信息，并根據(jù)上下文進(jìn)行邏輯推理，概括歸納，從而選出正確答案。7．閱讀理解 If American waterways had ever been voted on the yearbook, the Buffalo River could easily have been named Ugliest. It could be hard to find hope there. It took decades for public perception of the river to shift. But activist citizens, who collaborated with industry, government, and environment groups never gave up on their polluted river—the Buffalo River gradually went from being considered a lost cause to a place worth fighting for. And by now the cleaned—up water is one of Buffalo39。S biggest attractions. By the 1960s, the river was seen as one of the worst sources of pollution pouring into the Great Lakes. The Buffalo River had caught fire many times. The surface had an oily layer, and any fish caught there were not eatable. The waterway39。s fate started shifting in the mid1960s. Stanley Spisiak was a local Polish—American jeweler by day, but by evening he was the kind of guy who39。d chase down dumpers(垃圾車)he spotted on the Buffalo River. By 1966 he found himself winning the National Wildlife Federation39。s Water Conservationist of the Year award. And before long he got a nickname: Mr. Buffalo River. But there was only so much he could do—the river was still declared biologically dead in 1969. Jill Spisiak Jedlicka is his greatgrandniece. She picks up where he left off by directing the river39。s protector organization, Buffalo Niagara Waterkeeper. Professor Schneekloth and seven friends founded the organization as an allvolunteer nonprofit in 1989, after organizing the first river cleanup that year. Today the group employs 27 fulltime workers and has helped oversee the Buffalo River39。s $100 million restoration. So far, the Buffalo River39。s water quality has restored, but it is still an ongoing issue, as sewage(污水)can overflow into the river after storms. Habitat restoration continues as well。 fish and plantings are still being sampled to measure how well it39。s gone. （1）What did the Buffalo River use to be? A.A waterway on the yearbook.B.A river heavily polluted.C.A great attraction of Buffalo39。s.D.A place worth fighting for.（2）Why was named Mr. Buffalo River? A.Because his fate shifted in the 1 960s.B.Because he spotted dumpers on the River.C.Because he spared no efforts to protect the river.D.Because the river was declared biologically dead.（3）How long did it take for the river to restore? A.More than half a century.B.Just four decades.C.About 30 years.D.Only 27 years.（4）What can be a suitable title for this text? A.The restoration of the Buffalo RiverB.Stanley Spisiak: The RiverC.The future of the Buffalo RiverD.River protection: A long way to go【答案】 （1）B（2）C（3）A（4）A 【解析】【分析】本文是一篇記敘文，講述了被污染的the Buffalo River的恢復(fù)。 （1）考查細(xì)節(jié)理解。根據(jù)第一段中的”never gave up on their polluted river—the Buffalo River gradually went from being considered a lost cause to a place worth fighting for.“；第二段中的”By the 1960s，the river was seen as one of the worst sources of pollution pouring into the Great Lakes. The Buffalo River had caught fire many times. The surface had an oily layer，and any fish caught there were not eatable.“可知，the Buffalo River過去是一條被嚴(yán)重污染的河。故選B。 （2）考查推理判斷。根據(jù)第三段中的
