46. What do we learn from a newly published study about cats?
- A. They can be trained to understand the physical world.
- B. They know what kind of prey might be easier to hunt.
- C. They have a natural ability to locate animals they hunt.
- D. They are capable of telling which way their prey flees.
答案：C
答案句：According to a newly published study, cats seem to be able to predict the location of hiding prey（猎物）using both their ears and an inborn（天生的）understanding of how the physical world works.
参考译文：根据一项新发表的研究，猫似乎能够利用它们的耳朵和对物理世界如何运作的天生理解来预测隐藏猎物的位置。
定位线索：题干“newly published study”→答案句首句“According to a newly published study”；文中“predict the location of hiding prey”对应选项C“locate animals they hunt”；文中“inborn”对应选项C“natural ability”。
解析：题干问从新研究中学到什么，答案句直接说明猫能预测隐藏猎物的位置，且用“inborn”强调天生能力，对应C选项“natural ability to locate animals they hunt”。A项“被训练”无中生有；B项“哪种猎物更容易捕猎”和D项“逃跑方向”均未提及。
49. In what way do babies behave like cats?
- A. They focus on what appears odd.
- B. They view the world as normal.
- C. They do what they prefer to do.
- D. They are curious about everything.
答案：A
答案句：Like cats, babies appear to engage in what's called “preferential looking”-looking longer at things that are interesting or unusual than things they perceive as normal.
参考译文：和猫一样，婴儿似乎会进行所谓的“优先注视”——对有趣或不寻常的事物注视的时间比他们认为正常的事物更长。
定位线索：题干“babies behave like cats”→答案句“Like cats, babies”；文中“looking longer at things that are interesting or unusual”对应选项A“focus on what appears odd”；文中“unusual”对应“odd”。
解析：题干问婴儿与猫相似的行为，答案句指出婴儿对“interesting or unusual”事物注视更久，即关注异常事物，对应A项。B项“视为正常”与原文相反；C项“做喜欢的事”偷换概念；D项“对一切好奇”程度过重。
