12、 C. September, 2004 D. any time练习二That people often experience trouble sleeping in a different bed in unfamiliar surroundings is a phenomenon known as the “first-night” effect. If a person stays in the same room the following night they tend to sleep more soundly. Yuka Sasaki and her colleagues at B
13、rown University set out to investigate the origins of this effect.Dr. Sasaki knew the first-night effect probably has something to do with how humans evolved. The puzzle was what benefit would be gained from it when performance might be affected the following day. She also knew from previous work co
14、nducted 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 might be doing the same thing. To take a closer look, her team studied 35 healthy people as they
15、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 that looked at the activity of their brains. Dr. Sasaki found, as expected, the participants slept le
16、ss 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 seen in birds and dolphins. On the first night only, the left hemispheres (半球) of their brains d
17、id 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 re-ran the experiment while presenting the sleeping participants with a mix of regularly timed beeps (蜂鸣
18、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 the irregular beeps by stirring people from sleep and would ignore the regularly timed ones. This
19、 is precisely what she found.1. What did researchers find puzzling about the first-night effect?A. To what extent it can trouble people. C. What circumstances may trigger it.B. What role it has played in evolution. D. In what way it can be beneficial.2. What do we learn about Dr. Yuka Sasaki doing h

She conducted studies on birds and dolphins sleeping patterns.3. What did Dr. Sasaki do when she first d

She recorded participants adaptation to changed environment.C. She exposed her participants to two different stimuli.D. She compared the responses of
