【正文】 Compared with solar and wind energy, which are booming, tidal (潮汐的) power is a loser in the clean energy petition. But if you did want to build a tidal power station, there are few better sites than the mouth of the River Severn, in Britain. Its tidal range, the difference in depth between high and low tides, of around 15 metres is among the largest in the world. 【點(diǎn)評(píng)】本題考點(diǎn)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(jìn)行分邏輯推理，從而選出正確答案。由此可知本文屬于科普文章。為了證實(shí)是否可能，研究人員養(yǎng)了18只這種鵝，并在大型風(fēng)洞中訓(xùn)練它們飛行。 （4）考查推理判斷。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(yīng)性變化能否可以飛行8小時(shí)爬上珠穆朗瑪峰。 （3）考查推理判斷。這兩處綜合推斷出，鵝可以在最低濃度的氧氣中生存。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(fēng)洞實(shí)驗(yàn)表明，當(dāng)氧氣濃度最低時(shí)，鵝的心率和翅膀搏動(dòng)頻率保持不變，即使它們的新陳代謝率下降。 （2）考查推理判斷。由此可推斷出研究人員飼養(yǎng)這種鵝是為了證實(shí)這種鵝是否能飛過(guò)珠峰。再根據(jù)最后一段中的So it39。根據(jù)第一段中的In 1953, a mountain climber reported seeing a barheaded goose soar over the peak of Mount Everest. It was thought impossible. 報(bào)道說(shuō)，一名登山者看到一只斑頭鵝飛過(guò)珠穆朗瑪峰。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(shí)間只有幾分鐘，因此能否飛過(guò)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(diǎn)評(píng)】本題考點(diǎn)涉及細(xì)節(jié)理解，詞義猜測(cè)，推理判斷和段落大意四個(gè)題型的考查，是一篇科研類閱讀，要求考生在捕捉細(xì)節(jié)信息的基礎(chǔ)上，進(jìn)一步根據(jù)上下文的邏輯關(guān)系，進(jìn)行分析，推理，概括和歸納，從而選出正確答案?？v觀全文可知，本文介紹了一項(xiàng)科學(xué)研究的研究成果，所以該文章最有可能出現(xiàn)在“技術(shù)與科學(xué)”版塊。故選B。 （3）考查細(xì)節(jié)理解。根據(jù)常識(shí)可知，在大自然中散步對(duì)人體有各種各樣的好處，再結(jié)合句中出現(xiàn)的“relieving other mood disorders(緩解其他情緒紊亂)”不難推斷出， batting depression應(yīng)表示“減輕抑郁”?！癛esearchers …surveyed 149 respondents aged 21 o 65 about the proportion of green space in their neighborhood…”研究人員調(diào)查了年齡在21~65歲之間的149名參與者小區(qū)內(nèi)的綠植比例……；以及“The study also asked questions about experiences with depression and anxiety…”研究中還問(wèn)了與抑郁及焦慮有關(guān)的問(wèn)題……等可知，第二段主要介紹了新研究的調(diào)查內(nèi)容，故選D。 （1）考查段落大意。s risk of developing mental health problems as an adult.（1）What does the second paragraph mainly talk about? results of the new study. purpose of the new study. significance of the new study. content of the new study.（2）What does the underlined word batting in paragraph 4 probably mean? ...（3）According to the passage, the new study _____. referred to exercise in nature enriched the previous research to some degree carried out by the University of Michigan exposure to greenery helped cure mental problems（4）n which section of a newspaper may this passage appear?
