Bird Migration
A
Birds have many unique design features that enable them to perform such amazing feats of endurance. They are equipped with lightweight, hollow bones, intricately designed feathers providing both lift and thrust for rapid flight, navigation systems superior to any that man has developed, and an ingenious heat conserving design that, among other things, concentrates all blood circulation beneath layers of warm, waterproof plumage, leaving them fit to face life in the harshest of climates. Their respiratory systems have to perform efficiently during sustained flights at altitude, so they have a system of extracting oxygen from their lungs that far exceeds that of any other animal. During the later stages of the summer breeding season, when food is plentiful, their bodies are able to accumulate considerable layers of fat, in order to provide sufficient energy for their long migratory flights.
B
The fundamental reason that birds migrate is to find adequate food during the winter months when it is in short supply. This particularly applies to birds that breed in the temperate and Arctic regions of the Northern Hemisphere, where food is abundant during the short growing season. Many species can tolerate cold temperatures if food is plentiful, but when food is not available they must migrate. However, intriguing questions remain.
C
One puzzling fact is that many birds journey much further than would be necessary just to find food and good weather. Nobody knows, for instance, why British swallows, which could presumably survive equally well if they spent the winter in equatorial Africa, instead fly several thousands of miles further to their preferred winter home in South Africa’s Cape Province. Another mystery involves the huge migrations performed by arctic terns and mudflat-feeding shorebirds that breed close to Polar Regions. In general, the further north a migrant species breeds, the further south it spends the winter. For arctic terns this necessitates an annual round trip of 25,000 miles. Yet, en route to their final destination in far-flung southern latitudes, all these individuals overfly other areas of seemingly suitable habitat spanning two hemispheres. While we may not fully understand birds’ reasons for going to particular places, we can marvel at their feats.
D
One of the greatest mysteries is how young birds know how to find the traditional wintering areas without parental guidance. Very few adults migrate with juveniles in tow, and youngsters may even have little or no inkling of their parents’ appearance. A familiar example is that of the cuckoo, which lays its eggs in another species’ nest and never encounters its young again. It is mind boggling to consider that, once raised by its host species, the young cuckoo makes it own way to ancestral wintering grounds in the tropics before returning single-handedly to northern Europe the next season to seek out a mate among its own kind. The obvious implication is that it inherits from its parents an inbuilt route map and direction-finding capability, as well as a mental image of what another cuckoo looks like. Yet nobody has the slightest idea as to how this is possible.
E
Mounting evidence has confirmed that birds use the positions of the sun and stars to obtain compass directions. They seem also to be able to detect the earth’s magnetic field, probably due to having minute crystals of magnetite in the region of their brains. However, true navigation also requires an awareness of position and time, especially when lost. Experiments have shown that after being taken thousands of miles over an unfamiliar landmass, birds are still capable of returning rapidly to nest sites. Such phenomenal powers are the product of computing a number of sophisticated cues, including an inborn map of the night sky and the pull of the earth’s magnetic field. How the birds use their ‘instruments’ remains unknown, but one thing is clear: they see the world with a superior sensory perception to ours. Most small birds migrate at night and take their direction from the position of the setting sun. However, as well as seeing the sun go down, they also seem to see the plane of polarized light caused by it, which calibrates their compass. Traveling at night provides other benefits. Daytime predators are avoided and the danger of dehydration due to flying for long periods in warm, sunlit skies is reduced. Furthermore, at night the air is generally cool and less turbulent and so conducive to sustained, stable flight.
F
Nevertheless, all journeys involve considerable risk, and part of the skill in arriving safely is setting off at the right time. This means accurate weather forecasting, and utilizing favorable winds. Birds are adept at both, and, in laboratory tests, some have been shown to detect the minute difference in barometric pressure between the floor and ceiling of a room. Often birds react to weather changes before there is any visible sign of them. Lapwings, which feed on grassland, flee west from the Netherlands to the British Isles, France and Spain at the onset of a cold snap. When the ground surface freezes the birds could starve. Yet they return to Holland ahead of a thaw, their arrival linked to a pressure change presaging an improvement in the weather.
G
In one instance a Welsh Manx shearwater carried to America and released was back in its burrow on Skokholm Island, off the Pembrokeshire coast, one day before a letter announcing its release! Conversely, each autumn a small number of North American birds are blown across the Atlantic by fast-moving westerly tail winds. Not only do they arrive safely in Europe, but, based on ringing evidence, some make it back to North America the following spring, after probably spending the winter with European migrants in sunny African climes.

Reading Passage 2. Bird Migration
题目详解
Questions 14-20
思 路
这种题型忌讳寻找主题句或**句，因为每个人对段落**思想的判断通常不同，而且每个段落的首尾句也不一定是主题句或**句，所以*好的解答方法应该是通过对每位考生都能读懂的标题进行反向思维，然后和段落内容进行比较，排除作答。
i. The best moment to migrate
如果某段落选这个标题，则该段落应该**讲述鸟儿在冬天到来之前的什么时候或多久就开始迁徙，以及有什么可能的标志，例如**片树叶落下或树叶变黄等等之类。
ii. The unexplained rejection of closer feeding ground
如果某段落选这个标题，则该段落应该讲到鸟儿迁徙到一个相对较近的地方就可以过冬，但它们却没有这样做，反而喜欢迁徙到较远的地方，这种现象是始料未及的。段落中除了对这种现象的描述之外，还可能有对这种现象的分析和解释。
iii. The influence of weather on the migration route
反向思维词：weather, migration route
如果某段落选这个标题，则该段落应该出现具体的天气状况以及不同的天气状况对鸟儿迁徙路线的影响，其中还可能出现具体的路线，也就是路线起止的地名等等。
iv. Physical characteristics that allow birds to migrate
反向思维词：physical characteristics
如果某段落选这个标题，则该段落应该具体提及鸟儿的一些生理特征，例如体型、羽毛，或解剖学特征，例如骨骼等，对飞行的影响。
v. The main reason why birds migrate
不容易进行反向思维，可以结合段落阅读进行判断。但是，可以猜测如果某段落选这个标题，则该段落应该在开头或结尾。
vi. The best wintering grounds for birds
反向思维词：wintering grounds
如果某段落选这个标题，则该段落应该出现具体的鸟儿过冬地点、具体的地名之类的列举，并陈述它们为什么是*好的等等。
vii. Research findings on how birds migrate
如果某段落选这个标题，则该段落应该出现关于鸟儿迁徙方面的一系列研究发现，还可能出现具体的对应的科学家或科学机构等等。
viii. Successful migration despite trouble of wind
反向思维词：wind
如果某段落选这个标题，则该段落应该会提及风，以及风对鸟儿迁徙的影响。
ix. Contrast between long-distance migration and short-distance migration
反向思维词：long-distance migration, short-distance migration
如果某段落选这个标题，则该段落应该出现具体的涉及距离的信息，也就是数字，并对两种迁徙进行比较。可以结合具体的比较句型进行判断。
x. Mysterious migration despite lack of teaching
反向思维词：teaching
如果某段落选这个标题，则该段落应该提及鸟儿没有学习却仍然能够成功迁徙的现象及可能的原因解析。

解 答
14. Paragraph A. 该段落明显提及鸟类诸多生理和解剖结构上的特点利于鸟类飞行，例如“lightweight, hollow bones, intricately designed feathers”，“navigation systems superior to any that man has developed, and an ingenious heat conserving design”等等，并且其他标题的信息均未提及。所以正确答案为iv。
15. Paragraph B. 段落开头便开章明义地提出鸟类迁徙的基本原因是为了食物，全段都是围绕这个内容进行阐述的。所以正确答案为v。
16. Paragraph C. 段落开头提及标题ii的信息“rejection of closer feeding ground”，后面继续说到没有人知道这是为什么，并且举例说明。在段落后面继续提及这种现象的一个规律“the further north a migrant species breeds, the further south it spends the winter”。同时，其他标题信息也没有出现。所以正确答案为ii。
17. Paragraph D. 该段落主要是讲鸟类不需要“parental guidance”便能够找到自己的“wintering areas”，然后以杜鹃鸟（cuckoo）举例说明这个现象，并在*后提出可能的解释“The obvious implication is that it inherits from its parents an inbuilt route map and direction-finding capability, as well as a mental image of what another cuckoo looks like”。该段落虽然出现“wintering grounds”信息对应标题vi （The best wintering grounds for birds），但是并未提及什么样的地方才是鸟类*好的过冬之地，所以应该排除。于是，与该段落对应的**标题只有x（Mysterious migration despite lack of teaching），“teaching”对应原文“parental guidance”，“mysterious”对应原文“One of the greatest mysteries”和“Yet nobody has the slightest idea as to how this is possible”。所以正确答案为x。
18. Paragraph E. 该段落比较明显地提及了鸟类迁徙时辨别方向的机制，比如利用太阳和星星，利用地球磁场等等，这些信息都对应标题vii（Research findings on how birds migrate），虽然没出现具体的科学家或机构。段落*后提及的“Traveling at night provides other benefits”虽然对应标题i（The best moment to migrate），但是该段落并不是主要在讲鸟类应该在晚上迁徙或应该在什么时间迁徙，而是主要讲鸟类如何在迁徙时辨别方向，所以应该排除。正确答案为vii。
19. Paragraph F. 该段落开头提及“…part of the skill in arriving safely is setting off at the right time”对应标题i（The best moment to migrate），次句又提及“weather”对应标题iii（The influence of weather on the migration route），和“winds”对应标题viii（Successful migration despite trouble of wind），但是全段只是在讲鸟类有能力对气候变化做出*及时的反应（“react to weather changes before there is any visible sign of them”），并藉此选择*佳的迁徙时刻，并未提及具体的不同天气状况怎样影响鸟类迁徙路线，也未具体讲风的内容，所以标题iii和标题viii都应排除。所以正确答案为i。
20. Paragraph G. 段落以一个例子引出鸟类可以不受美洲和欧洲之间风的影响自由迁徙的事实，明显对应标题viii（Successful migration despite trouble of wind），且其他标题信息都未提及，所以正确答案为viii。

Questions 21-22
思 路
这种多选多的选择题具有信息分散的特点，且通常具有归纳总结性特征，在雅思阅读中属于难题，所以应该放在做题顺序的*后，在其余细节题做完之后再来解答，此时更容易定位。做题过程中，只能对每一个选项进行原文定位，阅读原文信息并判断。
解 答
选项A 该信息明显对应C段落所述内容“many birds journey much further than would be necessary”，所以为正确选项。
选项B 全文**提及“family”相关信息的地方是在D段落，但是这里并没有讲到“traveling in family groups”**，只是提及鸟类没有父母指引仍然能寻觅到自己的过冬之地。全文**提及“safe”相关信息的地方是在段落E，但是也没有讲到“traveling in family groups”**，只是提及夜晚飞行相对**，因为“Daytime predators are avoided and the danger of dehydration due to flying for long periods in warm, sunlit skies is reduced”。所以该选项应该排除。
选项C 该信息对应E段落的倒数第二句话“the danger of dehydration due to flying for long periods in warm, sunlit skies is reduced”，也就是说夜晚飞行“need less water”。所以为正确选项。
选项D 原文虽然提及鸟类有较出色的身体构造，适合飞行，有比人类更敏锐的对天气变化感知的能力，有出色的认知方位的能力，但是却没有任何地方提及鸟类的“eye-sight”比人类出色，所以该选项应该排除。
选项E 原文G段落确实提及有些鸟类不会受到风的影响，可以自由横渡大西洋，原文只是说“each autumn a small number of North American birds…”，但是并未提及是只有“shorebirds”才能这样，所以该选项应该排除。
综上所述，正确答案为A，C。

Questions 23-26
23. 利用细节信息“young birds”，“cuckoos”和“wintering grounds”可以很容易定位到原文D段落**句话“One of the greatest mysteries is how young birds know how to find the traditional wintering areas without parental guidance”，所以正确答案为parental guidance。
24. 利用细节信息“the sun and the stars”定位于原文E段落**句话“Mounting evidence has confirmed that birds use the positions of the sun and stars to obtain compass directions”，所以正确答案为compass。
25. 利用细节信息“flying at night”定位于原文E段落倒数第二、三句话“Traveling at night provides other benefits. Daytime predators are avoided…”，所以正确答案为predators。
26. 利用细节信息“Laboratory tests”和“weather”定位于原文F段落“Birds are adept at both, and, in laboratory tests… birds react to weather changes before there is any visible sign of them”，所以正确答案为visible。
参考译文
鸟类迁徙
A
鸟类有许多独特的结构特征，使得它们表现出令人惊叹的耐久力。鸟类拥有极轻的体重、中空的骨骼、复杂的羽毛，这些为快速飞行提供了上升力和推动力。同时，鸟类还拥有比人类发明的任何导航系统都要优越的导航体系。此外，它精密的热保护结构会保证其温暖防水羽毛之下的血液循环的畅通，以便它们能够适应*恶劣的气候环境。鸟类必须具备极为**的呼吸系统才能适应高空的持久飞行，因此，它们从肺部提取氧气的呼吸系统比任何其他物种的都**得多。在食物丰富的夏季繁殖季后期，它们的体内会储存大量脂肪层，为它们长途迁徙飞行提供充足的能量。
B
鸟类迁徙主要是为了在冬季食物短缺时寻找到足够的食物。尤其是那些生长在北半球温带和北极圈地区的鸟类，因为这些地方只有在短暂的生长季节才会有充足的食物。在食物充足的情况下，很多鸟类都能忍受寒冷的天气，但当食物缺乏时，它们就不得不迁徙。然而，目前还存在一些令人不解的问题。
C
一个令人不解的现象是，很多鸟类的旅程距离远远长于它们为寻找食物和好天气所必需飞行的距离。例如，没人知道为什么本可以在非洲赤道区过冬的英国燕子非要不远千里飞到南非的开普省过冬。另一个谜团则是关于北极燕鸥以及在北极附近滩涂区哺育生活的水禽的大规模迁徙活动。通常，鸟类生活繁殖的地方越偏北，其冬季迁徙的地方就越偏南。对于北极燕鸥来说，它们每年的旅程长达25,000英里。但是，在飞往遥远的位于南纬度地区的目的地的途中，所有这些鸟类都会飞越许多地跨两个半球，看上去适合栖息的地区。虽然我们可能无法完全理解鸟类前往特定地区的原因，但是，我们也对鸟类游历世界的能力感到无比惊讶。
D
*大的谜团之一是幼鸟是如何在没有父母引导的情况下找到传统越冬之地的。成年的鸟类很少带领幼鸟一起迁徙，稚鸟甚至很少或者从没见过其父母。以布谷鸟（杜鹃）为例，它们将蛋产在其它鸟类的巢中，然后再也不会回去看望幼仔。让人惊讶的是，当小杜鹃在宿主家里长大后，它便会自己飞到其祖先在热带地区的越冬地，然后独自飞回北欧，寻找和自己同种类的配偶。这有力地说明了杜鹃能够从其父母那里继承内置的迁徙路线图和方向定位的能力，以及其他杜鹃鸟的外在长相的精神意象。然而，还没有人知道这究竟是怎么一回事。
E
越来越多的证据显示，鸟类能够利用太阳和星辰的方位来辨别方向。同时，它们似乎还能侦测地球磁场，这可能是由于鸟类脑部具有微小的磁性晶体的缘故。不过，真正的导航还需要对位置和时间的认知，特别是在迷路的时候。实验表明，当鸟儿被带出数千英里，跨越陌生的大陆板块之后，它们仍能迅速地回到自己的巢址。这种惊人的能力是对大量复杂的线索进行精密计算的结果，包括天生的夜空星图和地球磁场的拉力。鸟类是如何运用它们的“工具”的，我们还不得而知，但有一点是显而易见的：它们用比人类更**的感官知觉来观察这个世界。大部分幼鸟在夜间进行迁徙，并通过日落的位置辨别方位。但是，当它们观察日落时，似乎还能观测到日落带来的偏极光，从而矫正它们��方位。夜间飞行还有其他好处。鸟类可以避开昼行食肉动物，并减少温暖日照下长时期飞行带来的脱水危险。此外，夜间的空气通常较为凉爽，很少有空气湍流，这有利于持续稳定的飞行。
F
然而，所有的旅程都暗含着危险，要想**到达，其中一个要诀就是在正确的时间出发。这意味着要能准确地预测天气，并能合理地利用风向。鸟类从出生伊始就精通此道了。实验室测试还发现，有些鸟类甚至能够辨别出房间中天花板和地面之间气压的细微差别。通常，鸟类在有明显征兆前就能感应到即将发生的天气变化。鸟头麦鸡，一种生活在草原的鸟类，能够在寒流到来前从荷兰向西飞到不列颠群岛、法国和西班牙。当地表结冰时，它们可能会饿死。在冰雪消融之前，鸟儿们会再回到荷兰，它们是通过气压变化来预测天气转变的。
G
以威尔士马恩岛海鸥为例，它们被带到美国，然后再被释放，但是，在宣布被释放的消息之前，它们就已经飞回自己的住所——彭布罗克郡海岸线外的斯科克霍尔姆（Skokholm）岛了！相反地，每个秋天都会有少量的北美鸟类被快速移动的西尾风刮到大西洋的另一边。它们不仅**地到达了欧洲，而且越来越多的证据显示，其中一些可能还和欧洲候鸟们一起去了阳光充沛的非洲地区过冬，然后才在次年春天飞回北美。
