Section C（题干） Directions: There are 2 passages in this section. Each passage is followed by some questions or unfinished statements. For each of them there are four choices marked A), B), C) and D). You should decide on the best choice and mark the corresponding letter on Answer Sheet 2 with a single line through the centre. Passage One Questions 46 and 50 are based on the following passage. 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 Brown 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 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 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 university’s 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 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 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 re-ran the 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 the irregular beeps by stirring people from sleep and would ignore the regularly timed ones. This is precisely what she found. What did researchers find puzzling about the first-night effect？ A. To what extent it can trouble people.
B.What role it has played in evolution.
C. What circumstances may trigger it.
D.In what way it can be beneficial.
What do we learn about Dr. Yuka Sasaki doing her research？A.She found birds and dolphins remain alert while asleep.
B.She found birds and dolphins sleep in much the same way.
C.She got some idea from previous studies on birds and dolphins
D.She conducted studies on birds’ and dolphins’ sleeping patterns.
What did Dr. Sasaki do when re-running her experiment？A.She analyzed the negative effect of irregular tones on brains.
B.She recorded participants’ adaptation to changed environment.
C.She exposed her participants to two different stimuli.
D.She compared the responses of different participants.
What did Dr. Sasaki find about the participants in her experiment？A.They tended to enjoy certain tones more than others.
B.They tended to perceive irregular beeps as a threat.
C.They felt sleepy when exposed to regular beeps.
D.They differed in their tolerance of irregular tones.
What did Dr. Sasaki do when she first did her experiment？A.She monitored the brain activity of participants sleeping in a new environment.
B.She recruited 35 participants from her Department of Psychological Sciences.
C.She studied the differences between the two sides of participants’ brains.
D.She tested her findings about birds and dolphins on human subjects.
Directions: There are 2 passages in this section. Each passage is followed by some questions or unfinished statements. For each of them there are four choices marked A, B, C and D. You should decide on the best choice.
Several recent studies have found that being randomly (随机地) assigned to a roommate of another race can lead to increased tolerance but aliso to a greater likelihood (可能性) of conflict.
Recent reports found that lodging with a student of a different race may decrease prejudice and compel students to engage in more ethnically diverse friendships.
An Ohio State University study also found that black students living with a white roommate saw higher academic success throughout their college careers. Researchers believe this may be caused by social pressure.
In a New York Times article, Sam Boakye—the only black student on his freshman year floor—said that " if you're surrounded by whites, you have something to prove. "
Researchers also observed problems resulting from pairing interracial students in residences.
According to two recent studies, randomly assigned roommates of different races are more likely to experience conflicts so strained that one roommate will move out.
An Indiana University study found that interracial roommates were three times as likely as two white roommates to no longer live together by the end of the semester.
Grace Kao, a professor at Penn said she was not surprised by the findings. " This may be the first time that some of these students have interacted, and lived, with someone of a different race, " she said.
At Penn, students are not asked to indicate race when applying for housing.
" One of the great things about freshman housing is that, with some exceptions, the process throws you together randomly, " said Undergraduate Assembly chairman Alec Webley. "This is the definition of integration. "
" I've experienced roommate conflicts between interracial students that have both broken down stereotypes and reinforced stereotypes, " said one Penn resident advisor(RA). The RA of two years added that while some conflicts "provided more multicultural acceptance and melding (融合) , " there were also "jarring cultural confrontations. "
The RA said that these conflicts have also occurred among roommates of the same race.
Kao said she cautions against forming any generalizations based on any one of the studies, noting that more background characteristics cf the students need to be studied and explained.
What can we learn from some recent studies?
A．Conflicts between students of different races are unavoidable.
B．Students of different races are prejudiced against each other.
C．Interracial lodging does more harm than good.
D．Interracial lodging may have diverse outcomes.
