【正文】 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)理解和主旨大意兩個(gè)題型的考查，是一篇科研類(lèi)閱讀，考生需要準(zhǔn)確捕捉細(xì)節(jié)信息，并根據(jù)上下文的邏輯關(guān)系，進(jìn)行概括和歸納，從而選出正確答案。為什么這些人非常吸引蚊子呢？可知，本文探討的話(huà)題是：為什么一些人比其他人更容易招蚊子。根據(jù)第二段中的“According to Smithsonian Magazine, around 20 percent of people in the world are especially tasty to mosquitoes. What about these people makes mosquitoes39。故選B。根據(jù)最后一段中的“Scientists remend that we use insect repellent and wear lightcolored clothing.”科學(xué)家建議我們使用驅(qū)蟲(chóng)劑或者穿淺顏色的衣服。故選B。根據(jù)第七段“This love for CO2 can also put pregnant women at increased risk for mosquito bites, as they tend to exhale 21 percent more CO2 than people of the same age and size who aren39。故選C。根據(jù)第四段中的“While flying along, they use their sense of smell to find possible targets. They find victims by smelling the carbon dioxide (CO2) breathed out by humans and animals. ”飛的時(shí)候，它們用嗅覺(jué)發(fā)現(xiàn)目標(biāo)。s the article mainly about? new finding about mosquitoes. people can avoid mosquito bites. popular myth about mosquitoes. some people are more attractive to mosquitoes than others.【答案】 （1）C（2）B（3）B（4）D 【解析】【分析】本文是一篇說(shuō)明文，介紹了為什么有些人可以整個(gè)夏天坐在戶(hù)外乘涼卻不被蚊子叮咬，而有些人一出門(mén)就好像要被蚊子吃掉一樣。Being bitten by mosquitoes is annoying, but don39。 In addition to carbon dioxide, the color of the clothes you wear also plays a role in attracting mosquitoes.This love for CO2 can also put pregnant women at increased risk for mosquito bites, as they tend to exhale 21 percent more CO2 than people of the same age and size who aren39。As a result, people who simply exhale (呼出) more of the gas over time – generally, larger people – have been shown to attract more mosquitoes than others. This is why kids don39。 s why you monly find them in crowded streets and parks. s not plicated. The two most important reasons a mosquito is attracted to you have to do with sight and smell.A popular myth claims that mosquitoes prefer certain blood types, but the fact is that they simply can39。re not alone. According to Smithsonian Magazine, around 20 percent of people in the world are especially tasty to mosquitoes. What about these people makes mosquitoes39。 re being eaten alive within minutes of stepping outdoors. 6．閱讀理解 A選項(xiàng)的描述 糧食生產(chǎn)可導(dǎo)致約20%的人為造成的溫室氣體，而只使用了三分之一的無(wú)冰土地 正確，故選A。caused greenhouse gas emissions.”地球上三分之一的無(wú)冰區(qū)被用于農(nóng)業(yè)生產(chǎn)，根據(jù)一些估算，食物生產(chǎn)大約占到了人類(lèi)造成的溫室氣體排放量的五分之一。根據(jù)第三段中的“A third of the ice173。takes a big toll on固定短語(yǔ)，“付出了巨大的代價(jià)”，故選B。肥料徑流也導(dǎo)致了其他問(wèn)題，例如伊利湖的藻類(lèi)爆發(fā)以及墨西哥灣的死亡區(qū)域。free land on Earth is used for agriculture, and according to some estimates, producing food accounts for roughly a fifth of all human173。 （2）考查詞義猜測(cè)。t explicitly mention—environmental impacts, that you are going to have lower environmental impacts due to that.” 我們發(fā)現(xiàn)（營(yíng)養(yǎng)膳食指南的）影響因國(guó)家而異，但總的來(lái)說(shuō)，在影響力較大的國(guó)家，如果你遵循國(guó)家推薦的膳食指南，即使這些膳食并未明晰對(duì)環(huán)境的影響，或者大多數(shù)膳食沒(méi)有明確說(shuō)明這一點(diǎn)，但是你對(duì)環(huán)境的影響會(huì)因?yàn)樽裱改隙鴾p輕。impact nations, in general, you can see that, if you follow a nationally remended diet, despite the fact that these diets don39。 （1）考查推理判斷。t effected much.【答案】 （1）C（2）B（3）A 【解析】【分析】本文是一篇說(shuō)明文，介紹了營(yíng)養(yǎng)指南對(duì)地球也有利。 new program concerning healthy eating for schools is likely to be based on national nutrition guidelines.D.It is estimated that following dietary guidelines can lead to decrease in more land use than in nutrient pollution.C.caused greenhouse gas with only a third of the ice173。makes up for（3）Which of the following is TRUE according to the passage?
