考题共用题干 In Your FaceWhy is this man so angry?We don't know the reason,but we can see the emotion in his face.What- ever culture you come from,you can understand the feeling that he is expressing.Forty years ago,psychologist Paul Ekman of the University of California,San Francisco,became interested in how people's faces show their feelings.He took photographs of Americans expressing various emotions.Then he showed them to the Fore people,who live in the jungle in New Guinea. Most of the Fore had never seen foreign faces,but they easily understood Americans' expressions of anger,happiness,sad- ness,disgust,fear,and surprise.Then Ekman did the same experiment in reverse.He showed pictures of Fore faces to Americans,and the results were similar. Americans had no problems reading the emotions on the Fore people's faces. Ekman's research gave powerful support to the theory that facial expressions for basic emotions are the same everywhere.He did more research in Japan,Brazil,and Argentina,and got the same results.According to Ekman,these six emotions are universal because they are built into our brains.Theydeveloped to help us deal with things quickly that might hurt us.Some emotional triggers are universal as well.When something suddenly comes into sight,people feel fear,because it might be dangerous.But most emotional triggers are learned.For example,two people might smell newly cut grass.One person spent won- derful summers in the country as a child,so the smell makes him happy.The other person remembers work- ing very hard on a farm and being hungry,so he feels sad.Once we make an emotional association in our brain,it is difficult,and sometimes impossible,to change it."Emotion is the least changeable part of the brain,"says Ekman.But we can learn to manage our emotions better. For instance,we can be more aware of things that make us angry,and we can think before we react.There are many differences between cultures,in their languages and customs.But a smile is exactly the same everywhere.Two people might feel different emotions about the same thing.A:RightB:WrongC:Not mentioned

考题资料：In a survey,people were asked to choose between treatments to save 600 people from dying a disease. Participants,including physicians,were asked to choose between a certain outcome that 200 people will be saved and a risky choice where there is a one-third probability that 600 people will be saved and a two-thirds probability that no people will be saved. In a second example,the group were asked to choose between allowing 400 people to die or a one-third probably that nobody will die and two-thirds probability that 600 people will die. In both examples,the first choices have an identical outcome as do their second alternatives.But faced with such a grave choice people did not spot the similarities. In the first example people opted to save 200 people over the gamble of losing people and in the second example people preferred the gamble over the certain outcome of killing 400 people. What the experiment shows is that wording can have potentially dangerous consequences.Most of people tend to feel losses much more strongly than the pleasure of making a comparable gain. In the second example，more people choose the option（）？ A.with a one-third probability that nobody will die B.with a two-thirds probability that nobody will be saved C.allowing 400 people to die D.that 200 people will be saved

考题共用题干第一篇The Smell of MoneyFor many years large supermarkets have been encouraging us to spend money by pumping the smell of freshly-baked bread into their stores. Now Dale Air, a leading firm of aroma（香气）consultants, has been approached by Barclay's Bank to develop suitable artificial smells for their banks.Researchers have suggested that surrounding customers with the"smell of money"will encourage them to feel relaxed and optimistic and give them added confidence in the bank's security and professionalism.But before a smell can be manufactured and introduced into banks' air conditioning systems,it must be identified and chemically analyzed,and this has proved to be difficult.The problem is that banknotes and coins tend to pick up the smell of their surroundings.So cash that has been sitting in a cash register at a fishmonger's（鱼贩）will smell of fish,and banknotes used to pay for meals in restaurants will tend to smellof food.It may be a challenge,but aroma experts have little doubt that the use of artificial smells can be an effective form of subconscious advertising. Lunn Poly,a British travel company,introduced the smell of coconuts（椰子）into its travel agencies and saw a big increase in spending by holiday makers.Many cafs now have elec-tric dispensers（自动售货机）that release the smell of freshly roasted coffee near their entrances, subtly encouraging customers to come in and have a drink or snack. Even prestigious car maker Rolls-Royce has been spraying the inside of its cars to enhance the smell of the leather seats."The sense of smell is probably the most basic and primitive of all human senses,"explains researcher Jim O'Riordan. "There is a direct pathway from the olfactory（嗅觉的）organs in the nose to the brain."It is certainly true that most people find certain smells incredibly strong,stirring memories and feelings in a way that few other stimulants（刺激物）can rival.

The mole（痣）was later found to be skin cancer.Carolyn Willis led a team of researchers at Amersham Hospital in England.They trained different kinds of dogs for the experiment. The study involved urine collected from bladder cancer patie nts,from people with other diseases and from healthy people.Each dog was tested eight times.In each test there were seven samples for the dogs to smell.The dog was supposed to signal the one from a bladder cancer patient by lying down next to it.Two cocker spaniels（短腿长毛垂耳小猎犬）were correct fifty-six percent of the time. But the scientists reported an average success rate of forty-one percent.As a group,the study found that the dogs chose the correct sample twenty-two out of fifty-four times .That is almost three times more often than would be expected by chance alone.The British Medical Journal published the research .In all,thirty-six bladder cancer patients and one hundred and eight other people took part.During training,all the dogs reportedly even identified a cancer in a person who had testedhealthy before the study.Doctors found a growth on the person's right kidney（肾）.Bladder cancer is the ninth most common cancer worldwide.The International Agency for Research on Cancer says this disease kills more than one hundred thousand people each year.
