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. The team trained the youngsters to fly in a large wind tunnel wearing backpacks and face masks full of sensors that recorded their heart rate. blood oxygen levels, temperature, and metabolic rate—how many calories they burned per hour. The researchers simulated(模擬)10w, medium, and highaltitude conditions by altering the concentration of oxygen supplied to face masks worn by each goose as it flew in the tunnel. 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. The wind tunnel experiments showed that when the concentration of oxygen was at its lowestlike the 7% found on top of Mount Everest versus 21% at sea level—the geese39。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. Although well trained, the birds were only willing to stay in the air a few minutesor less when wearing their backpacks and flying at 6ihigh altitudes. So it39。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?

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。人們認為這是不可能的；以及 Now researchers who raised 19 of the geesenamed for the black stripes on the backs of their headshave shown the birds really fly so high.現(xiàn)在研究人員飼養(yǎng)了這種鵝，他們發(fā)現(xiàn)這些鵝真的飛得很高。再根據(jù)最后一段中的So it39。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.但是否能讓這種鵝飛8小時爬上珠穆朗瑪峰尚不清楚。由此可推斷出研究人員飼養(yǎng)這種鵝是為了證實這種鵝是否能飛過珠峰。故選B。 （2）考查推理判斷。根據(jù)第四段中的The wind tunnel experiments showed that when the concentration of oxygen ...the geese39。s heart rate and frequency of wing beats remained the same even as their metabolic rate dropped....the researchers report today in elife. This cooling likely helps p可知 風洞實驗表明，當氧氣濃度最低時，鵝的心率和翅膀搏動頻率保持不變，即使它們的新陳代謝率下降。研究人員今天在《伊利費》雜志上報道說，...這種降溫可能有助于補償空氣的稀??；第五段中的Although well trained, the birds were only willing to stay in the air a few minutesor less ... 盡管訓練有素，但這些鳥只愿意在空中呆上幾分鐘。這兩處綜合推斷出，鵝可以在最低濃度的氧氣中生存。故選C。 （3）考查推理判斷。根據(jù)最后一段中的So it39。s not clear whether these adaptations alone are what make it possible to fly the 8 hours it takes to climb over Mount Everest. 可知，目前尚不清楚的是，只有這些適應性變化能否可以飛行8小時爬上珠穆朗瑪峰。故選D。 （4）考查推理判斷。第一段中提到登山者報告說看到一只長頸鵝翱翔在珠穆朗瑪峰的頂峰。為了證實是否可能，研究人員養(yǎng)了18只這種鵝，并在大型風洞中訓練它們飛行。結(jié)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。由此可知本文屬于科普文章。故選D。 【點評】本題考點涉及推理判斷題型的考查，是一篇科研類閱讀，要求考生根據(jù)上下文進行分邏輯推理，從而選出正確答案。5．閱讀理解 An experimental cleanup device called RemoveDEBRIS has successfully cast a net around a dummy (仿真的) satellite, imitating a technique that could one day collect spaceborne garbage. The test, which was carried out this week, is widely believed to be the first successful demonstration of space cleanup technology, experts told CNN. And it symbolizes an early step toward solving what has already been a critical issue: junk in space. Millions of pieces of junk are turning around in orbit the result of 50 years of space travel and few regulations to keep space clean. At orbital speeds, even a small bit of paint crashing with a satellite can cause critical damage. Various panies have plans to send thousands of new satellites into lowEarth orbit, already the most crowded area. The RemoveDEBRIS experiment is run by a pany and researchers led by the U. K.39。s Surrey Space Center and includes Airbus, Airbusowned Surrey Satellite Technology Ltd. and France39。s ArianeGroup. Guglielmo Aglietti, the director of Surrey Space Center, said that an operational version of the RemoveDEBRlS technology would cast a net that remains fastened to the main satellite so the debris can be dragged out of orbit. It could target large
