If a person stays in t
14、he same room the following night they tend to sleep more soundly. Yuka Sasaki and her colleagues at Brown University set out to investigate the origins of this effect.Dr Sasaki knew the firstnight effect probably has something to do with how humans evolved.The puzzle was what benefit would be gained
15、 from it when performance might be affected the following day. She also knew from previous work conducted on birds and dolphins that these animals put half of their brains to sleep at a time so that they can rest while remaining alert enough to avoid predators (捕食者). This led her to wonder if people
16、 might be doing the same thing. To take a closer look, her team studied 35 healthy people as they slept in the unfamiliar environment of the universitys Department of Psychological Sciences. The participants each slept in the department for two nights and were carefully monitored with techniques tha
17、t looked at the activity of their brains. Dr Sasaki found, as expected, the participants slept less well on their first night than they did on their second, taking more than twice as long to fall asleep and sleeping less overall. During deep sleep, the participants brains behaved in a similar manner
18、 seen in birds and dolphins. On the first night only, the left hemispheres (半球) of their brains did not sleep nearly as deeply as their right hemispheres did.Curious if the left hemispheres were indeed remaining awake to process information detected in the surrounding environment, Dr Sasaki reran th
19、e experiment while presenting the sleeping participants with a mix of regularly timed beeps (蜂鸣声) of the same tone and irregular beeps of a different tone during the night. She worked out that, if the left hemisphere was staying alert to keep guard in a strange environment, then it would react to th
20、e irregular beeps by stirring people from sleep and would ignore the regularly timed ones. This is precisely what she found.这篇文章的主题和睡眠环境有关，在一个陌生的环境里，人们睡在陌生的床上通常会无法入眠，心理学家们将这种现象称之为“初夜”效应。本文围绕着睡眠环境和研究者的调查内容与结论展开叙述。1What do we learn about Dr Yuka Sasaki doing her research?AShe found birds and dolphins

22、nimals put half of their brains to sleep at a time so that they can rest while remaining alert enough to avoid predators (捕食者). This led her to wonder if people might be doing the same thing. Dr Yuka Sasaki从先前对鸟类和海豚的实验中知道动物在睡觉时左半侧大脑远没有右半侧大脑睡得深，这样可以使它们在休息时保持对捕食者的警惕，表明动物在睡眠状态时的大脑活动是不对称的，Sasaki好奇人类情况是否
23、类似。可以得知对人类睡眠实验的想法来源于之前对鸟和海豚做的实验。故选C。答案：C2What did Dr Sasaki do when she first did her experiment?AShe monitored the brain activity of participants sleeping in a new environment.BShe recruited (招募) 35 participants from her Department of Psychological Sciences.CShe studied the differences between the

This
29、is precisely what she found.得知Sasaki博士在实验中发现当人们在陌生环境中睡觉时，左半侧大脑保持清醒以警惕陌生环境，对随机发出的哔哔声有所反应将人们从睡眠中叫醒，并且同时会忽略定时发出的哔哔声。可以推断出人们会把随机发出的哔哔声视作一个威胁。故选B。答案：B.概要写作阅读下面短文，根据其内容写一篇60词左右的内容概要。If you havent seen alpaca meat (羊驼肉) on the menu yet, chances are you soon will.
