根据下列材料请回答 26~30 题:BToday 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.第 26 题 In 1700, the men who protected the streets were paid __________.A. a fewB. nothingC. a littleD. a lot

Between about 1910 and 1930, new artistic movements in European art were making themselves felt in the United States. American artists became acquainted with the new art on their trips to Paris and at the exhibitions in the famous New York gallery “291”( named after its address on Fifth Avenue) of the photographer Alfred Stieglitz. But most important in the spread of the modern movements in the United States was the sensational Armory Show of the 1913 held in New York, in which the works of many of the leading European artists were seen along with the works of a number of progressive American painters. Several of the American modernists who were influenced by the Armory Show found the urban landscape, especially New York, an appealing subject. Compared with the works of the realist painters, the works of American modernists were much further removed from the actual appearance of the city; they were more interested in the “feel “ of the city, more concerned with the meaning behind appearance. However, both the painters of the Ash Can School” and the later realists were still tied to nineteenth-century or earlier styles, while the early modernists shared in the international breakthroughs of the art of the twentieth century.The greatest of these breakthroughs was Cubism, developed most fully in France between 1907 and 1914, which brought about a major revolution in Western painting. It overturned the regional tradition that had been built upon since the Renaissance. In cubism, natural forms were broken down analytically into geometric shapes. No longer was a clear differentiation made between the figure and the background of a painting: the objects represented and the surface on which they were painted became one. The Cubists abandoned the conventional single vantage point of the viewer, and objects depicted from multiple viewpoints were shown at the same way.51.What’s the main topic of the passage?A.

题库1. What extracurricular activities were you involved in? What made you choose those? Which of them did you most enjoy, and why?

Text 1"The love of money",St Paul memorably wrote to his protege Timothy,"is the root of all evil.""All"may be putting it a bit strongly,but dozens of psychological studies have indeed shown that people primed to think about money before an experiment are more likely to lie,cheat and steal during the course of that experiment.Another well-known aphorism,ascribed to Benjamin Franklin,is"time is money".If true,that suggests a syllogism:that the love of time is a root of evil,too.But a paperjust published in Psychological Science by Francesca Gino of Harvard and Cassie Mogilner of the University of Pennsylvania suggests precisely the opposite.Dr Gino and Dr Mogilner asked a group of volunteers to do a scries of what appeared to be aptitude tests.As is ofien the case in such experiments,though,what the voiunteers were told.and what the truth was,were rather different things.In the first test they were asked to make,within three minutes,as many coherent sentences as they could out of a set ofwords they had been presented with.What they were not told was that each of them had been assigned to one of three groups.Some volunteers'word sets were seeded with ones associated with money,such as"dollars","financing"and"spend".Some were seeded with words associated with time(eg,"clock",/'hours","moment").And some were seeded with neither.Thus unknowingly primed,the volunteers were ready for the second test.This was mathematical.They were given a sheet of paper with 20 matrices which each contained 12 numbers.two of which added up to ten(for example,3.81 and 6.19).They had to write down,on a separate answer sheet,how many of these pairs they could manage to find in five minutes.They were also given a packet ofmoney and told they could reward themselves with a dollar for each pair they discovered.This led Dr Gino and Dr Mogilner to suspect that self-reflection played a part in controlling uncthical behaviour during the test.They therefore conducted a third test in which,for half the volunteers,there was a mirror in the cubicle they were sitting in when doing the experiment.Volunteers primed to think about money cheated 39%of the time when a mirror was present but 67%when it was not.Those primed to think about time cheated 32%of the time in the presence of the mirror and 36%in its absence-results that are statistically indistinguishable.Finally,a fourth experiment asked primed volunteers to fill in a questionnaire before tackling the matrix.In among"filler"questions intended to disguise what was happening this asked them to rate how they felt about self-reflective statements like,"Right now,1 am thinking about who I am as a person."As in the previous tests,those primed with money words cheated more ofien than those primed with neutral words and far more ofien than those primed with time words.But whether someone cheated was also related to how strongly he felt about the self-reflective statements presented to him in the questionnaire.It seems,then,that thinking about time has the opposite effect on people from thinking about money.It makes them more honest than normal,rather than less so.Moreover,the more reflective they are,the more honest they become.There must be an aphorism in that.What can we infer from the tests?A.The subjects have been told their assignmentB.Volunteers who had been primed with money ideas were more likely to cheat others.C.12%volunteers had been primed with time-related words.D.33%subjects had been primed with money-related words.

共用题干第二篇Sleep Necessary for MemoriesBurning the midnight oil before an exam or interview does harm to the performance according to a recent research which found that sleep is necessary for memories to betaken back into the brain.A good night's sleep within 30 hours of trying to remember a new task is a required condition of having good recall in the weeks ahead,scientists have found.The research,published in the December issue of Nature Neuroscience,showed that it was the act of sleep,rather than the simple passage of time,that was critical for long-term memory formation."We think that getting that first night's sleep starts the process of memory consolidation (巩固),"said Robert Stickgold, a sleep researcher at Harvard Medical School who conducted the latest study."It seems that memories normally wash out of the brain unless some process nails them down.My suspicion is that sleep is one of those things that does the nailing down," Professor Stickgold said.With about one in five people claiming that they are so chronically short of sleep that it affects their daily activities,the latest work emphasizes the less well一understood side effect一serious memory impairment(损害).Volunteers in an experiment found it easier to remember a memory task if they were allowed to sleep that night.But for those kept awake,no amount of subsequent sleep made up for the initial loss.Professor Stickgold's team trained 24 people to identify the direction of three diagonal (斜线形的)bars flashed for a sixtieth of a second on a computer screen full of horizontal (水平的)stripes.Half of the subjects were kept awake that night,while the others slept.Both groups were allowed to sleep for the second and third nights to make up for any differences intiredness between the volunteers.Those who slept the first night were significantly and consistently better at remembering the task while the second group showed no improvement despite enjoying two nights of catch-up sleep.In Stickgold's experiment,those who were kept awake on the first nightA:could very well remember the direction of the diagonal bars.B:didn't do any better after two nights' sleep.C:were as tired as those who were not.D:could recall the direction of more bars than those who were not.

问答题Passage 2  (1) A one-month survey results indicate that smoking, alcohol and marijuana use increase among residents of Manhattan during the five to eight weeks after the terrorist attacks on the World Trade Center which took place on September 11, 2001. Almost one-third of the nearly 1000 persons interviewed reported an increased use of alcohol, marijuana, or cigarettes following the September 11 attacks. About one-fourth of the respondents said they were drinking more alcohol in the weeks after September 11; about one tenth reported an increase in smoking, and 3.2% said they had increased their use of marijuana.  (2) The investigators found survey participants by randomly dialing New York City phone numbers and screened potential respondents for Manhattan residents living in areas close to the World Trade Center. Interviews were conducted with 988 individuals between October 16 and November 15, 2001. Participants were asked about their cigarette smoking, alcohol drinking, and marijuana use habits before and after September 11. During the week prior to September 11, 2001, 22.6% of the participants reported smoking cigarettes, 59.1% drinking alcohol, and 4.4% using marijuana. After September 11, 23.4% reported smoking cigarettes, 4.4% drinking alcohol, and 5.7% smoking marijuana. Among those who smoked, almost 10% reported smoking at least an extra pack of cigarettes a week and among those who drank alcohol, more than 20% reported imbibing at least one extra drink a day.  The researchers found that people who reported an increase in substance abuse were more likely to suffer from post-traumatic stress disorder (PTSD) and from depression (3) people who reported an increase in cigarette smoking or marijuana use were also more likely to have both PTSD and depression, while those people who reported an increase in alcohol use were more likely to have depression only. (4) Persons who were living closer to the World Trade Center were more likely to increase their cigarette smoking, but other factors such as being displaced from one’s home, losing possessions during the attacks, or being involved in the rescue efforts were not consistently associated with increased substance use. Symptoms of panic attack were associated with an increase in the use of all substances.  Increase in substance abuse did not differ significantly between men and women or among racial or ethnic groups. (5) Demographic factors such as age, marital status, and income seemed tip play a more critical role in determining if the events of September 11 led to an increase in substance use.
