It was thought impossible. 報道說，一名登山者看到一只斑頭鵝飛過珠穆朗瑪峰。結果發(fā)現(xiàn)這種鵝可以在氧氣極低的情況下飛行，但停留時間只有幾分鐘，因此能否飛過珠峰尚不明確。D.C.B.Whether they can manage to fly 8 hours to climb over Mount Everest.（4）Where does the text most probably e from? A.Whether they have muscles pumped more oxygen to.C.It shows the geese could fly at high altitude for long.（3）What still puzzles scientists about the geese? A.The geese managed to breathe less when their blood decreased.C.To see how many calories they burned per hour.（2）What can we learn from the wind tunnel experiment? A.To confirm they could fly over Mount Everest.C.s not clear whether these adaptations alone are what make it possible to fly the 8 hours it takes to climb over Mount Everest. But those few minutes showed these geese really could fly over the top of Mount Everest.（1）Why did the researchers raise 19 barheaded geese and train them? A.s heart rate and frequency of wing beats remained the same even as their metabolic rate dropped. Somehow, the birds managed to cool down their bloodthe measured blood temperature dropped so it could take in more oxygen, the researchers report today in eLife. This cooling likely helps pensate for the very thin air, the team says. Birds already have a better heart and lungs than mammals for sustained physical activity. And researchers knew that barheaded geese have even larger, thinner lungs that let them breathe more deeply and an even bigger heart to pump more oxygen to muscles than other birds. In 1953, a mountain climber reported seeing a barheaded goose soar over the peak of Mount Everest (珠穆朗瑪). It was thought impossible. Now researchers who raised 19 of the geese—named for the black stripes on the backs of their heads—have shown the birds really fly so high. 【點評】本題考點涉及推理判斷，詞義猜測和主旨大意三個題型的考查，是環(huán)保類閱讀，考生需要根據(jù)上下文的邏輯關系，進行分析，推理，概括和歸納，從而選出正確答案。雖然政府發(fā)誓解決污染問題，但周末的能見度低，數(shù)百架航班在周末改道、延誤和取消，學校和辦公室周一關閉，人們必須戴防污口罩，可知，新德里被嚴重的污染所籠罩。 （4）考查主旨大意。由此可判斷“emitted”是排放的意思。因為天氣變冷，從汽車和以煤為基礎的發(fā)電廠“emitted”的污染物形成了厚厚的霧霾。 （3）考查詞義猜測。由此可知，由于污染嚴重，學校、大學、醫(yī)院和市場分發(fā)了數(shù)百萬個防污染口罩。根據(jù)第四段“Hundreds of flights were diverted, delayed and canceled over the weekend due to poor visibility, schools and offices were closed Monday and officials rushed to take emergency measures to try to reverse the eroding air quality. Millions of antipollution masks were distributed at schools, colleges, hospitals and markets.” 周末期間，由于能見度低，數(shù)百架航班被迫改道、延誤和取消，學校和辦公室周一關閉，官員們緊急采取措施，試圖扭轉不斷惡化的空氣質量。故選B。可知，政府盡管發(fā)誓解決這種污染，但情況不僅沒有改變，反而更加嚴重，使得人們必須佩戴防毒口罩。s most polluted city.” 新德里每年都會被污染吞沒，隨著天氣變冷，汽車和以煤為基礎的發(fā)電廠排放的污染物、建筑工地和道路上飄動的灰塵，以及鄰國農(nóng)作物秸稈燃燒產(chǎn)生的煙霧，都會形成濃霧。 （1）考查推理判斷。 . Caused by the Development of New Delhi Pollution Envelops New Delhi Masks Are in Great Need in New Delhi in the Neighboring States are to Blame for Burning Crop Stubble【答案】 （1）B（2）C（3）A（4）B 【解析】【分析】本文是一篇說明文，隨著城市的發(fā)展和越來越多的人口流動，城市規(guī)模的擴大，印度的新德里成為世界上污染最嚴重的城市。 s air quality index, which measures a mix of dangerous pollutants, registered an average score of 494 Sunday. That is the highest 24hour average since Nov. 6, 2016, when it hit 497, according to data measured by the Central Pollution Control Board.（1）Which of the following is NOT true? is one of the most important festivals in India. government did little to protect its citizens against the serious pollution. a serious air pollution in New Delhi appears on a regular basis. index of the recent air pollution is not the worst in the history.（2）Who may not plain about the serious air pollution? parents whose children have to stay at home. pilots whose planes have been diverted or delayed. manufacturers who produce antipollution masks. officials who have to work out of their offices.（3）Which of the following phrases can replace the underlined word in paragraph 5? out. up. in. on.（4）The title of the passage should be s most polluted city. Hundreds of flights were diverted, delayed and canceled over the weekend due to poor visibility, schools and offices were closed Monday and officials rushed to take emergency measures to try to reverse the eroding air quality. Millions of antipollution masks were distributed at schools, colleges, hospitals and markets. With the development of the city and more and more people moving, the city has expanded several times in size. That is why it is called New Delhi. New Delhi, a city with a population of over 20 million people, has its newest problem: never before has this city met with the worst air problem.Delhi has been the centre of a succession of mighty empires and powerful kingdoms in India. Numerous ruins scattered throughout the territory offer a constant reminder of the area39。 【點評】本題考點涉及細節(jié)理解和推理判斷兩個題型的考查，是一篇科技類閱讀，考生需要準確捕捉細節(jié)信息，并根據(jù)上下文進行邏輯推理，從而選出正確答案。
