It’s easy to think that the globe’s vast oceans would be effective barriers to the movement of land animals．An elephant can’t swim across the Pacific, after all．But it turns out that plenty of plants and animals have unintentionally floated across oceans from one continent to another．Now comes evidence that tiny, trapdoor spiders（蜘蛛）made such a journey millions of years ago．Moggridgea rainbowi spiders can be found on Kangaroo Island, which sits off the south coast of Australia．These spiders build a silk﹣lined hole in the ground, notes Sophie Harrison, a biologist in Australia．The hole and trapdoor provide these spiders with shelter and protection．It also provides them an out﹣of﹣sight spot from which to wait for approaching creatures．There is evidence, though, that the ancestors of ________ might have traveled millions of meters to get to Australia from Africa．That isn’t as unlikely as it might at first seem．Australia used to be connected to other continents, long ago, as part of a supercontinent called Gondwana．And humans have been known to transport species all over the planet．But there’s a third option．The spiders might have rafted（乘筏）long distances across the sea．To figure out which story was most likely true, Harrison and her colleagues looked at the spider’s genes．They looked at the genes in seven Moggridgea rainbowi spiders from Kangaroo, and five species of Moggridgea spiders from South Africa．The Australian and African spiders split off from a common ancestor some 2 million to 16 million years ago, the genes showed．If a large swatch of land washes into the sea, filled with arachnids（蛛形纲动物）, the spiders may be able to hide themselves throughout the journey．Plus, they can“hold their breath”and survive on stored oxygen during periods of temporary flooding, the researchers note．（1）What is the common belief about land animals according to the text？________A.They are sensitive to natural disasters．B，They are unlikely to move across oceans．C.They can’t make a long ocean voyage．D.They float across oceans accidentally．．（2）What does the underlined word “them” in Paragraph 3 refer to？________A.Biologists．B.Australians．C.The spiders．D.The creatures．．（3）How did the researchers conclude Australian and African spiders are from a common ancestor？________A.By comparing their genes．B.By observing their living habits．C.By making changes to their genes．D.By studying their physical characteristics．．（4）What could be the best title for the text？________A.These Spiders Traveled Globally to Hide ThemselvesB.These Spiders Became More Adaptive When TravelingC.These Spiders Crossed an Ocean to Australia for SurvivalD.These Spiders Crossed an Ocean to Become Australians naturally．【答案】BCAD【考点】阅读理解综合说明文阅读完形综合【解析】本文是一篇科教类阅读，文章主要介绍了人们很容易认为，地球上广阔的海洋将是陆地动物迁徙的有效屏障．一头大象不能游过太平洋，毕竟，许多植物和动物无意中漂洋过海，漂洋过海到另一个大陆．现在有证据表明，在数百万年前，微小的蜘蛛门蜘蛛已经踏上了这一旅程．【解答】（1）B．细节理解题．根据第一段"It’s easy to think that the globe’s vast oceans would be effective barriers to the movement of land animals．’ 很容易认为，地球上广阔的海洋将是陆地动物运动的有效障碍．可知根据文本，人们对陆地动物的共同认为是它们不太可能跨越海洋．故选B．（2）C．细节理解题．根据第三段“There is evidence， though， that the ancestors of them might have traveled millions of meters to get to Australia﹣from Africa’ 不过，有证据表明，他们的祖先可能走了数百万米才从非洲到达澳大利亚．可知”them“指的是”Thes piders’．故选C．（3）A．推理判断题．根据第四段"To figure out which story was most likely true，Harrison and her colleagues looked at the spider’s genes．’ 为了弄清楚哪个故事最有可能是真的，哈里森和她的同事们观察了蜘蛛的基因．可知研究人员通过比较他们的基因断定澳大利亚和非洲的蜘蛛来自同一个祖先．故选A．（4）D．推理判断题．根据第一段“Now comes evidence that tin y，trapdoor （活板门）spiders made such a journey millions of years ago．’可知”These Spiders Crossed an Oceanto Become Australians 现在有证据表明，微小的，陷阱门蜘蛛在数百万年前就进行了这样的旅程．“可知”这些蜘蛛穿越海洋成为澳大利亚人．这些蜘蛛穿过海洋变成了澳大利亚的"是本文最好的题目．故选D．4. For many, music is as important to the human experience as eating and breathing．We hear music everywhere at home, the gym, parties and stores．But what kind of music do we prefer to listen to, and when and why do our musical preferences change?The relationship between the change of seasons and musical preferences was the focus of a study led by psychologist Terry Pettijohn．He and his team based their research on a previous study that examined the relationship between popular music preferences and the Environmental Security Hypothesis（假设）．The results showed that over time, when social and financial conditions were more risky, the songs of the year that wereslower, longer, more comforting and serious were most popular． And during periods in which social and financial conditions were generally stable, the result is opposite．Building on these findings, Pettijohn and his team wondered if the Hypothesis could also be applied to the change of seasons． For college students, the participants in this study autumn begins at the start of the academic school year．Gone are me carefree days of summer, when school is out．When summer comes’clocks fall back, stealing an hour of daylight, which feel like losing precious time．Winter means colder temperatures, shorter days, and, in many places in the country, snow．Spring, however, is a different story．It represents a flesh starts and when clocks spring forward, we gain an extra hour of day light．As students walk into summer, they’re absorbed in the sunshine and social activity﹣and enjoy a break from schoo1．But do changing seasonal conditions influence musical preferences? To answer this question, the researchers designed two studies．What did they find? Both groups of college students favored more serious music during the seasons of fall and winter, and more active and energetic music during the spring and summer seasons．And these findings, Pettijohn argues, have practical significances．（1）What is the purpose of the question raised in Paragraph 1 ？________A.To present a different opinion on music．B.To prove where to listen to music matters．C.To introduce the topic on musical preferences．D.To stress the importance of music to humans．．（2）What influences a person’s choice of music types according to the previous study？________A.Whether one has enough free time．B.Whether one lives in a stable situation．C.Whether one is exposed to sunlight．D.Whether one chooses to change his life．．（3）What does Paragraph 3 imply？________A.Spring has a special meaning to people．B.Students aren’t fond of scho ol in any season．C.The Hypothesis disagrees with Pettijohn’s studies．D.The length of summer time is longer than winter time．．（4）How does Pettijohn feel about the findings of his studies？________A.It’s unexpected，B.It’s significant．C.It’s humorous．D.It’s discouraging．【答案】CBAB【考点】社会文化类阅读议论文阅读【解析】本文是一篇文学艺术类阅读，文章主要介绍了对许多人来说，音乐对人类的体验和吃饭和呼吸一样重要．我们到处都能听到音乐﹣﹣在家里、健身房、聚会和商店．但是我们喜欢听什么样的音乐，什么时候和为什么我们的音乐偏好发生变化．【解答】（1）C．推理判断题．根据第一段"But what kind of music do we prefer to listen to， and when and why do our musical preferences change？但是我们更喜欢听什么样的音乐，什么时候以及为什么我们的音乐偏好会改变’可知第1段提出的问题的目的是介绍关于音乐偏好的话题．故选C．（2）B．推理判断题．根据第二段"The results showed that over time， when social and financial conditions were more risky， the songs of the year that were slower， longer，more comforting and serious were most popular． And during periods in which social and financial conditions were generally stable， the result is opposite．结果表明，随着时间的推移，当社会和金融状况风险较大时，一年中节奏较慢、时间较长、较为舒适、较为严肃的歌曲最受欢迎，而在社会和金融状况总体稳定的时期，结果则相反’可知根据之前的研究，一个人是否生活在稳定的环境中影响了一个人的音乐类型选择．故选B．（3）A．推理判断题．根据第三段"Spring， however， is a different story． It represents a fresh starts and when clocks spring forward， we gain an extra hour of day light．然而，春天是另一个故事，它代表着一个新的开始，当时钟向前跳动时，我们获得了额外的一小时的白昼光’可知春天对人们有特殊的意义．故选A．（4）B．细节理解题．根据最后一段"And these findings， Pettijohn argues， have practical
