题目解答

答案

解析

听力篇章核心内容

文章主要讨论了鲨鱼的社交行为研究，打破了“鲨鱼是独居动物”的常见认知，指出鲨鱼具有类似哺乳动物的复杂社交网络，并介绍了研究方法和意义。

题目解析

22. 关于鲨鱼的正确陈述

文章开头明确提到：“Sharks are the first fish known to have networks of friends, just like mammals. Contrary to the common belief that sharks are solitary animals...”（鲨鱼是已知第一种拥有朋友网络的鱼类，就像哺乳动物一样。这与“鲨鱼是独居动物”的常见认知相反）。

  • A选项：“Sharks are the first fish known to have networks of friends.”（鲨鱼是已知第一种有朋友网络的鱼类）与原文完全一致；
  • B选项错误（与“独居”认知相反）；C、D选项错误（文章明确鲨鱼有社交网络和互动）。

23. 科学家如何发现鲨鱼的复杂社交结构

文章提到：“Using acoustic tracking devices, the oceanographer followed over 300 Sand Tiger sharks and recorded their interactions over the course of a year.”（海洋学家使用声学跟踪设备，追踪了300多条灰鲭鲨一年的互动）。

  • A选项：“They used the acoustic tracking devices.”（使用声学跟踪设备）符合原文；
  • B、C、D选项均未提及（未拍照、非实验室研究、未分组）。

24. 两条被监测鲨鱼的朋友数量

文章指出：“Initial data from two of the monitored sharks shows that... if the sharks were connected through 'Shark Social', they could have as many as 200 friends...”（两条被监测鲨鱼的初始数据显示，如果通过“鲨鱼社交”连接，它们可能有多达200个朋友）。

  • C选项：“200 friends.”符合原文；
  • A、B、D选项数字错误（17是“最好的朋友”数量，非总朋友数）。

25. Halusee对研究的期望

文章结尾提到：“Halusee hopes the research will inform conservation efforts as they can now map where sharks gather and when...”（Halusee希望研究能为保护工作提供信息，因为现在可以绘制鲨鱼聚集的时间和地点）。

  • D选项：“He hopes the research will provide conservation info to protect sharks.”（希望研究提供保护鲨鱼的 conservation 信息）符合原文；
  • A、B选项不全面（映射聚集区域和路线是手段，目的是保护）；C选项错误（非实验室研究）。
