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。It shows the geese could fly at high altitude for long.（3）What still puzzles scientists about the geese? A.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. 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.故選B。故選C。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。 A popular myth claims that mosquitoes prefer certain blood types, but the fact is that they simply can39。re being eaten alive within minutes of stepping outdoors.caused greenhouse gas emissions.”地球上三分之一的無冰區(qū)被用于農(nóng)業(yè)生產(chǎn)，根據(jù)一些估算，食物生產(chǎn)大約占到了人類造成的溫室氣體排放量的五分之一。free land on Earth is used for agriculture, and according to some estimates, producing food accounts for roughly a fifth of all human173。 （1）考查推理判斷。caused greenhouse gas with only a third of the ice173。Following a nationally remended diet can do good to our health.C.eating173。 Overall, in high173。free land on Earth is used for agriculture, and according to some estimates, producing food accounts for roughly a fifth of all human173。impact nations, in general, you can see that, if you follow a nationally remended diet, despite the fact that these diets don39。根據(jù)第三段中的“The argument goes that famers eat more cooked food and more dairy than hunter gatherers.”可知農(nóng)民比狩獵采集者吃更多的熟食和奶制品，即農(nóng)民們發(fā)f和v音的原因是他們喜歡吃更多的熟食。同時這也強調了人類特有的一切都是物質和精神的結合:語言必須把聲音和意義結合起來，沒有真實的物體，意義就不可能存在或傳播。C.. A.因此本文的最好的題目就是“狗能識別人的情緒”。根據(jù)第五段中的They guess it may be because dogs find angry faces disgusting, causing them to withdraw quickly以及However可知，與前面意思相反，以及劃線詞后的disappear可知once the smart dogs realized they were getting rewarded, the trepidation seemed to disappear.…此句為，狗看到生氣的表情后會感到厭惡，并由此退縮，但是一旦聰明的狗意識到會有獎勵之后，它們的恐懼以及退縮就會消失。s because the scientists believe humans show their emotions on their entire face.然而，它們也會釋放出有害 的故選C。millipedevulturebeing plain in taste at the discovery of a predatorB. While faking and fierce looks are among animals great defenses, many species know that everyone runs from a big stink (臭氣) too.根據(jù)第一段中的“to reach a newly revealed ecosystem that had been hidden for 120,000 years below the Larsen C ice shelf.”到達一個新發(fā)現(xiàn)的在拉森冰架下面隱藏了12萬年的的生態(tài)系統(tǒng)，可知選D。冰山下面顯現(xiàn)的新的海洋生態(tài)系統(tǒng)為科學家提供了研究未知的海洋生物的機會。It is as big as London.B.To study how the iceberg was formed.B. A team of international scientists is due to set off for the world39。 The calving of A68 provides us with a unique opportunity to study marine life as it responds to a huge environment change, she said. It is important that we get there quickly before the undersea environment changes as sunlight enters the water.s ocean will be, on average, at least 60cm higher by the end of the century. However, it found that the process is accelerating, and more than three quarters of the acceleration since 1993 is due to melting ice sheets in Greenland and Antarctica, the study shows.（1）Why are the scientists eager to go to the iceberg? A.The condition of animal species in Antarctica.（3）What can we learn about the A68 iceberg from the text? A.By 2100, the sea level will have risen to a much higher level than now.【答案】 （1）B（2）C（3）D（4）D 【解析】【分析】本文是一篇說明文，南極地區(qū)的拉森C冰架崩解形成了一座巨大的冰山A68 iceberg。 （3）考查細節(jié)理解。s eyes and face.t move any more than a human statue until the threat has passed.

A.The gas released by millipede was basically harmless.（3）The species that enjoys more than one defense mechanism is ________. A.C.Sea Hare (海兔)部分中的“The sea hare gives out a slimy, purple ink, the substance which makes food less palatable to predators.”可知，海兔身上散發(fā)出黏糊糊的紫色墨水，這種物質使得捕食者對食物不那么感興趣，從而保護自己免受捕食者的傷害。根據(jù)Millipedes (千足蟲)部分中的“Their major defense is to curl up into a ball. They, though, also release a harm eyes, and leave a horrible smell on their attackers.”可知，千足蟲主要防守是蜷成一團。 Interestingly, the dogs were not provided with the entire face.
