Questions are based on the following passage．
A research led by the University of Sydney has found that people often think otherpeople are stating at them even when they aren"t. When in doubt， the human brain is morelikely to tell its owner that he"s under the gaze of another person.
"Gaze perception——the ability to tell what a person is looking at——is a social cue thatpeople ofen take for granted，" says Professor Colin Clifford from the University"s Schoolof Psychology.
To tell if they"re under someone"s gaze， people look at the position of the otherperson"s eyes and the direction of their heads. These visual cues are then sent to the brainwhere there are specific areas that compute this information.
However， the brain doesn"t just passively receive information from the eyes. Thestudy shows that when people have limited visual cues， such as in dark conditions or whenthe other person is wearing sunglasses， the brain takes over with what it "knows".
The researchers created images of faces and asked people to observe where the faceswere looking. "We made it difficult for the observers to see where the eyes were pointedso they would have to rely on their prior knowledge to judge the faces" direction of gaze，"Professor Clifford explains. "It turns out that we"re likely to believe that others are staringat us， especially when we"re uncertain."
"There are several speculations to why humans have this bias，" Professor Cliffordsays. "Direct gaze can signal dominance or a threat， and if you perceive something as athreat， you would not want to miss it. So assuming that the other person is looking at youmay simply be a safer strategy. Also， direct gaze is often a social cue that the other personwants to communicate with us， so it"s a signal for an upcoming interaction."
"It"s important that we find out whether it"s innate or learned——and how this mightaffect people with certain mental conditions，" Professor Clifford says.
Research has shown， for example， that people who have autism （孤独症 ） are lessable to tell whether someone is looking at them. People with social anxiety， on the otherhand， have a higher tendency to think that they are under the stare of others.
"So if it is a learned behaviour， we could help them practice this task——onepossibility is letting them observe a lot of faces with different eyes and head directions，and giving them feedback on whether their observations are accurate."
What can we learn from the research led by the University of Sydney？ 查看材料
A.Human brain can tell if its owner is under someone"s gaze.
B.Human brain cannot identify other people"s gaze when in doubt.
C.People in doubt often think they are stared at by others.
D.People tend to stare at others when they are in doubt.

Washoe Learned American Sign Language
(1) An animal that influenced scientific thought has died. A chimpanzee named Washoe and born in Africa died of natural causes late last month at the age of 42 at a research center in the American state of Washington. Washoe had become known in the scientific community and around the world for her ability to use American Sign Language. She was said to be the first non-human to learn a human language. Her skills also led to debate about primates and their ability to understand language.
(2) Research scientists Allen and Beatrix Gardner began teaching Washoe sign language in1966. In 1969, the Gardners described Washoe&39;s progress in a scientific report. The people who experimented with Washoe said she grew to understand about 250 words. For example, Wasboe made signs to communicate when it was time to eat. She could request foods like apples and bananas. She also asked questions like, "Who is coming to play？"
Once the news about Washoe spread, many language scientists began studies of their own into this new and exciting area of research. The whole direction of primate research changed.
(3) However, critics argued Washoe only learned to repeat sign language movements from watching her teachers. They said she had never developed tree language skills. Even now there are some researchers who suggest that primates learn sign language only by memory, and perform. the signs only for prizes. Yet Washoe&39;s keepers disagree. Roger Fouts is a former student of the Gardners.
He took Washoe to a research center in Ellensburg, Washington. There, Washoe taught sign language to three younger chimpanzees, which are still alive.
(4) Scientists like private researcher Jane Goodall believe Washoe provided new information about the mental workings of chimpanzees. Today, there are not as many scientists studying language skills with chimps. Part of the reason is that this kind of research takes a very long time.
(5) Debate continues about chimps&39; understanding of human communication. Yet, one thing is sure--Washoe changed popular ideas about the possibilities of animal intelligence.

B.Report about washoe"s progress in learning sign language
C.General information about washoe

听力原文： Laughing at life is one of the best ways of guaranteeing it does not end prematurely, scientists said yesterday. Researchers found that people who often laugh out loud and see the funny side of difficult situations are far less likely to have a heart attack than humorless individuals.
The study looked at the humor responses of 150 patients who had either suffered heart attacks or undergone treatment for blocked arteries. They were compared with the responses of an identical number of age-matched healthy people who had no history of heart problems. There was some variation in the results, but, overall, it was found that the heart patients were 40% less likely than their healthy counterparts to laugh in a variety of common situations.
Michael Miller, director of the Center for Preventive Cardiology at the University of Maryland, Baltimore, who led the research, said: "The old saying that laughter is the best medicine appears to be true when it comes to protecting your heart."
The findings suggested that making oneself laugh when angry might offset the harmful effect of stress on arteries. The team's findings were presented yesterday at the American Heart Association's annual scientific meeting in New Orleans.

A．150 healthy people.
B．150 unhealthy people.
C．300 patients.
D．300 people.
