They make a long journey from their wintering grounds in Africa to raise their young on the British Isles. However, the cuckoo population in the UK is falling sharply. Since 1995, the number of breeding cuckoos has dropped by 35%. To understand why this is happening, 1 2 3 4 5 6 7 8 课 后 习 题 32 researchers at the British Trust for Ornithology (鸟类学) are now using high-tech equipment to find answers. Researchers have been attaching satellite tags (标签) to cuckoos, which send out real-time location data. This data reveals how long cuckoos spend in the UK, when they leave, and which migration routes they take between the UK and Africa. The hope is that this data will give scientists a detailed understanding of cuckoo migration, the threats they face along the way, and the conservation measures that could be adopted to 1 2 3 4 5 6 7 8 课 后 习 题 improve their chances of survival. The tags have already revealed many insights into cuckoo migration. It’s hoped that as data keeps coming in, scientists will better understand the factors that influence whether cuckoos survive their migration, and therefore the best ways to help protect the species. It’s not just the scientists who have been eagerly tracking the tagged birds, though. The tags provide live location data which is 1 2 3 4 5 6 7 8 课 后 习 题 published on an online map. Members of the public can therefore watch the cuckoos’ incredible journeys, too, and if you click on the individuals on the map, you can find out more about each bird. “This ongoing project opens a significant window on the wonders of migration, and our discoveries are helping to shape the way we look at bird migration more widely,” says lead scientist on the project, Dr Chris Hewson. “It will also lay a foundation from which cuckoo conservation measures can be planned, increasing the 1 2 3 4 5 6 7 8 课 后 习 题 likelihood that the call of these birds will grace our summers for generations to come.” 【文章大意】本文为一篇说明文。文章主要介绍了英国研究人员如何利用卫星追踪技术研究杜鹃数量锐减的原因。 1 2 3 4 5 6 7 8 课 后 习 题 ( )1.What is the purpose of the British Trust for Ornithology’s research? A.To find out why there are fewer and fewer cuckoos. B.To find out what happened to cuckoos’ habitat. C.To test out how to make an online map for Africa. D.To test out how high-tech equipment can be used in the research. √ 1 2 3 4 5 6 7 8 课 后 习 题 37 [解析] 细节理解题。根据文章第一段“However, the cuckoo population in the UK is falling sharply. Since 1995, the number of breeding cuckoos has dropped by 35%. To understand why this is happening, researchers at the British Trust for Ornithology (鸟类学) are now using high-tech equipment to find answers.”(然而,英国的杜鹃数量正在急剧下降。自1995年以来,繁殖的杜鹃的数量减少了35%。为了解这一现象发生的原因,英国鸟类学信托组织的研究人员正在使用高科技设备寻找答案。)可知,此研究的目的是找出杜鹃数量急剧下降的原因,故选A。 1 2 3 4 5 6 7 8 课 后 习 题 38 ( )2.How can the public be involved in the cuckoo tracking project according to the passage? A.By contributing funds to the research. B.By following the live location data online. C.By observing the birds in their natural habitat. D.By participating in bird-watching tours. √ 1 2 3 4 5 6 7 8 课 后 习 题 39 [解析] 细节理解题。根据文章第五段“The tags provide live location data which is published on an online map. Members of the public can therefore watch the cuckoos’ incredible journeys, too, and if you click on the individuals on the map, you can find out more about each bird.”(标签提供的实时位置数据会发布在在线地图上。因此公众也可以观看杜鹃不可思议的迁徙旅程,如果你点击地图上的个体鸟类,还能了解更多关于每只杜鹃的信息。)可知,公众可以通过在线地图实时追踪杜鹃的位置数据,从而观看杜鹃的迁徙旅程,故选B。 1 2 3 4 5 6 7 8 课 后 习 题 40 ( )3.Which statement may Dr Chris Hewson agree with about the project? A.It inspires the public’s passion for technology. B.It shows the exact population of cuckoos in the UK. C.It lays a foundation for the species’ conservation. D.It will help cuckoos choose a safer migration route. √ 1 2 3 4 5 6 7 8 课 后 习 题 41 [解析] 推理判断题。根据文章最后一段Dr Chris Hewson所说的话“It will also lay a foundation from which cuckoo conservation measures can be planned, increasing the likelihood that the call of these birds will grace our summers for generations to come.”(它还将为规划杜鹃保护措施奠定基础,增加这种鸟儿的鸣叫声在未来继续装点我们夏季的可能性。)可知,Dr Chris Hewson认为该项目为杜鹃保护奠定基础,故选C。 1 2 3 4 5 6 7 8 课 后 习 题 42 ( )4.Which of the following can be the best title for the passage? A.Cuckoos’ migration routes B.Conservation measures for birds C.Decline of new species in the UK D.Tracking cuckoos’ journeys √ 1 2 3 4 5 6 7 8 课 后 习 题 43 [解析] 主旨大意题。根据文章第一段“However, the cuckoo population in the UK is falling sharply. Since 1995, the number of breeding cuckoos has dropped by 35%.

This finding, published in the journal Biology Letters, came about due to an experimental error when researchers placed hibernating (冬眠的) queen bumblebees in water and found them alive days later. The discovery has impressed scientists, particularly because bumblebees are land-based creatures not typically associated with water environments. 1 2 3 4 5 6 7 8 课 后 习 题 45 Nigel Raine, a professor in the school of environmental sciences at the university and the study’s lead author, expressed his astonishment at the results. To further explore this phenomenon, Raine and his team conducted an experiment involving 143 hibernating queen bumblebees. They discovered that those placed underwater for up to seven days had similar survival rates to those not, indicating that the bees’ ability to survive such conditions may be more common than previously thought. The research underlines the strength of bumblebees 1 2 3 4 5 6 7 8 课 后 习 题 during their hibernation period, a critical phase in their life cycle that has remained largely unexplored. Queen bumblebees typically hibernate alone in small holes during the cold months, which are believed to protect them from flooding. However, this study reveals that these bees possess an unexpected adaptation, allowing them to survive even in flooded conditions. Given these findings, one possible explanation for their survival is diapause, a state of suspended growth and reproduction characterized by reduced oxygen intake. During this state, 1 2 3 4 5 6 7 8 课 后 习 题 bumblebees may close their spiracles (气孔) to prevent water from entering their bodies, and they might also breathe through their skin. This energy-saving mode is likely a key factor in their ability to survive beneath the water. Raine emphasized the importance of understanding these mechanisms, as it could have significant implications for the study of wild insects that help with plant reproduction, which are crucial for food security and ecosystem health. His team’s research will aim to 1 2 3 4 5 6 7 8 课 后 习 题 determine whether hibernating queens can survive even longer periods underwater and if similar strength exists in other bee species. 【文章大意】本文是说明文。一项研究发现,东部大黄蜂可以在水下生存长达一周,这种适应能力在以往未被发现。研究表明,大黄蜂在冬眠期间可能通过关闭气孔和减缓新陈代谢来实现这一生存技巧,这一发现对研究野生昆虫的生存机制具有重要意义。 1 2 3 4 5 6 7 8 课 后 习 题 ( )5.What do we know about the finding? A.It matched prior beliefs. B.It concerned sea insects. C.It was fully anticipated. D.It was made by accident.

The discovery has impressed scientists, particularly because bumblebees are land-based creatures not typically associated with water environments.”可知,这个发现是偶然的,而非预先计划的。故选D项。 √ 1 2 3 4 5 6 7 8 课 后 习 题 50 ( )6.What can be inferred about bumblebees from Paragraph 3? A.They hibernate in groups for protection. B.They are always protected from flooding. C.They have a hidden adaptation mechanism. D.They reproduce better in flooded conditions. [解析] 推理判断题。根据第三段“However, this study reveals that these bees possess an unexpected adaptation, allowing them to survive even in flooded conditions.”可知,研究发现大黄蜂在水下能够生存,这表明它们具备一种未被发现的适应机制,这一机制帮助它们在洪水这样的极端条件下生存。故选C项。 √ 1 2 3 4 5 6 7 8 课 后 习 题 51 ( )7.What may Nigel Raine do in the future? A.Secure research patents. B.Prioritize dietary security. C.Conduct further research. D.Raise ecological awareness. √ 1 2 3 4 5 6 7 8 课 后 习 题 52 [解析] 推理判断题。根据最后一段“Raine emphasized the importance of understanding these mechanisms, as it could have significant implications for the study of wild insects that help with plant reproduction, which are crucial for food security and ecosystem health. His team’s research will aim to determine whether hibernating queens can survive even longer periods underwater and if similar strength exists in other bee species.”可知,Nigel Raine强调了理解大黄蜂在水下存活机制的重要性,所以他将继续进行研究。故选C项。 1 2 3 4 5 6 7 8 课 后 习 题 53 ( )8.Which is the most suitable title for the text? A.Bumblebee reproductive habits B.Bumblebee hibernation patterns C.Scientists’ experimental methods D.Bumblebee survival underwater [解析] 主旨大意题。根据第一段“A recent study from the University of Guelph in Canada has revealed a surprising discovery about common eastern bumblebees (大黄蜂): √ 1 2 3 4 5 6 7 8 课 后 习 题 54 these insects can survive underwater for up to a week. This finding, published in the journal Biology Letters, came about due to an experimental error when researchers placed hibernating (冬眠的) queen bumblebees in water and found them alive days later.
