单选题The evidence for harmony may not be obvious in some families. But it seems that four out of five young people now get on with their parents, which is the opposite of the popularly-held image of unhappy teenagers locked in their room after endless family quarrels. An important new study into teenage attitudes surprisingly shows that their family life is more harmonious than it has ever been in the past. "We were surprised by just how positive today's young people seem to be about their families," said one member of the research team. "They' re expected to be rebellious and selfish, but actually they have other things on their minds: they want a car and material goods, and they worry about whether school is serving them well. There' s more negotiation and discussion between parents and children, and children expect to take part in the family decision-making process. They don't want to rock the boat." So it seems that this generation of parents is much more likely than parents of 30 years ago to treat their children as friends. "My parents are happy to discuss things with me and willing to listen to me," says 17-year-old Daniel Lazall. "I always tell them when I'm going out clubbing. As long as they know what I'm doing, they're fine with it." Susan Crome, who is now 21, agrees. "Looking back on the last 10 years, there was a lot of what you could call negotiation. For example, as long as I'd done all my homework, I could go out on a Saturday night. But I think my grandparents were a lot stricter with my parents than that." Maybe this positive view of family life should not be unexpected. It is possible that the idea of teenage rebellion is not rooted in real facts. A researcher comments, "Our surprise that teenagers say they get along well with their parents comes because of a brief period in our social history when teenagers were regarded as different beings. But that idea of rebelling and breaking away from their parents really only happened during that one time in the 1960s when everyone rebelled. The normal situation throughout history has been a smooth change from helping out with the family business to taking it over."

单选题We all have first impression of someone we just met. But why? Why do we form an opinion about someone without really knowing anything about him or her—aside perhaps from a few remarks or readily observable traits? The answer is related to how your brain allows you to be aware of the world. Your brain is so sensitive in picking up facial traits. Even very minor difference in how a person"s eyes, ears, nose, or mouth are placed in relation to each other makes you see him or her as different. In fact, your brain continuously processes incoming sensory information—the sights and sounds of your world. These incoming signals are compared against a host of "memories" stored in the brain areas called the cortex (皮质) system to determine what these new signals "mean". If you see someone you know and like at school, your brain says "familiar and safe". If you see someone new, it says, "new and potentially threatening". Then your brain starts to match features of this stranger with other "known" memories. The more unfamiliar the characteristics, the more your brain may say, "This is new, I don"t like this person." or else, "I"m intrigued (好奇的)". Or your brain may perceive a new face but familiar clothes, ethnicity, gestures—like your other friends; so your brain says: "I like this person". But these preliminary impressions can be dead wrong. When we stereotype people, we use a less mature form of thinking (not unlike the immature thinking of a very young child) that makes simplistic and categorical impressions of others. Rather than learn about the depth and breadth of people—their history, interest, values, strengths, and true character—we categorize them as jocks (骗子), peeks (反常的人), or freaks (怪人). However, if we resist initial stereotypical impressions, we have a chance to be aware of what a person is truly like. If we spend time with a person, hear about his or her life, hopes, dreams, and become aware of the person"s character, we use a different, more mature style of thinking—and the most complex areas of our cortex, which allow us to be humane.

单选题F Today there are policemen everywhere, but in 1700, London had no policemen at all. A few old men used to protect the city streets at night and they were not paid. About 300 years ago, London was starting to get bigger and more and more people began to live there. The city was very dirty and many people were poor. There were so many thieves who stole money in the streets that people stayed in their homes as much as possible. In 1750, Henry Fielding started to pay a group of people to stop thieves. They were like policemen and were called "Bow Street Runners" because they worked near Bow Street. Fifty years later, there were 120 "Bow Street Runners", but London had become very big and needed more policemen. So in 1829, the first Metropolitan(or London)Police Force was started with 3,000 officers. Most of the men worked on foot, but a few rode horses. Until 1920 all the police in London were men. Today, the London police are quite well paid and for the few police officers who still ride horses, the pay is even better than for the others.
