题目解析
31、Hibernation theory做大范围定位，hibernated underwater 可以做定位，同时跟 buried themselves是并列关系，注意并列提示信息，预判答案填名词。对应原文Another theory for the regular appearance and disappearance of birds was that they spent winter hidden in mud.这句话之前出现hibernate 和underwater,another theory表示跟前面的并列，原文中的hidden对应题干的buried, 答案填mud。
32、Transmutation theory,Aristotle做大范围定位，题干autumn,redstarts做定位，预判the loss of可能会出现替换，答案填名词，对应原文：He observed that in the autumn, small birds called 'redstarts' began to lose their feathers.Autumn, redstarts原文原词出现，lose 对应题干的loss, 答案为feathers。
33、Aristotle's assumptions做定位，预判答案填名词单数，对应原文：These assumptions are understandable given that this pair of species are similar in shape. Assumption是原词，understandable 对应题干的logical,this pair of species 对应 题干的two species of birds,similar是原词没有发生替换，答案为shape。
34、定位用17th century,Charles Morton,预判答案填地点名词，对应原文：He wrote a surprisingly well-regarded paper claiming that birds migrate to the moon and back every year. 此处a surprisingly well-regarded paper claiming对应题干中的 popularised the idea,migrate to对应题干中的fly to，答案填 moon。
35、用1822,stork,Germany,an African spear 题干定位，预判答案为名词，对应原文：One of the key moments in the development of migration theory came in 1822 when a white stork was shot in Germany.This particular stork made history because of the long spear in its neck.定位词都是原词出现，答案为neck。
36、定位用Africa, 题干中需注意previously 时间限制，以及no的否定，答案为名词，对应原文because it was the first evidence that storks spend their winters in sub-Saharan Africa.The first evidence对应题干的no,storks spend their winters in sub-Saharan Africa对应题干的storks migrate to Africa。答案为evidence。
37、little表否定需要关注，预判答案填名词跟 journeys并列，对应原文：Before this, very little information was available about the actual destinations of particular specie. Little 原词出现， was available 对应题干的was known，答案为destinations。
38、定位用large birds,small birds,预判答案填名词，huge可能会被替换，题干中出现incapable的否定要关注，对应原文：because it seemed impossible that small birds weighing only a few grams could fly over vast oceans. it seemed impossible对 应题干中的incapable,small birds 原词出现，fly over 对应题干中travel across, vast对应题干中的across, 答案是oceans。
39、用Ringing做定位，对应原文The development of bird ringing,by a Danish schoolteacher,Hans Christian Cornelius Mortensen,made many discoveries possible. This is still common practice today and relies upon what is known as 'recovery’relies upon 对应题干中的 depend on,is known as 对应题干中的is called，答案为recovery。
40、题干用1931，first,migration,European birds做定位，对应原文：and for the first time in history people understood where birds actually went to in winter.In 1931，an atlas was published showing where the most common species of European birds migrated to. 时间出现 ，European birds原词出现，migrated to 对应题干中的migration,was published对应题干中的was printed, 答案atlas。
