考题共用题干 More Than 8 Hours Sleep Too Much of a Good Thing1 Although the dangers of too little sleep are widely known,new research suggests that people who sleep too much may also suffer the consequences.2 Investigators at the University of California in San Diego found that people who clock up 9 or 10 hours each weeknight appear to have more trouble falling and staying asleep,as well as a number of other sleep problems,than people who sleep 8 hours a night. People who slept only 7 hours each night also said they had more trouble falling asleep and feeling refreshed after a night's sleep than 8-hour sleepers.3 These findings,which DL Daniel Kripke reported in the journal Psychosomatic Medicine,demonstrate that people who want to get a good night's rest may not need to set aside, more than 8 hours a night.He added that“it might be a good idea”for people who sleep more than 8 hours each night to consider reducing the amount of time they spend in bed,but cautioned that more research is needed to confirm this.4 Previous studies have shown the potential dangers of chronic shortages of sleep一for instance,one report demonstrated that people who habitually sleep less than 7 hours each night have a higher risk of dying within a fixed period than people who sleep more.5 For the current report,Kripke reviewed the responses of 1,004 adults to sleep questionaires,in which participants indicated how much they slept during the week and whether they experienced any sleep problems.Sleep problems included waking in the middle of the night,arising early in the morning and being unable to fall back to sleep,and having fatigue interfere with day-to-day functioning.6 Kridke found that people who slept between 9 and 10 hours each night were more like-ly to report experiencing each sleep problem than people who slept 8 hours.In an interview, Kripke noted that long sleepers may struggle to get rest at night simply because they spend too much time in bed. As evidence,he added that one way to help insomnia is to spend less time in bed.“It stands to reason that if a person spends too long a time in bed,then they'll spend a higher percentage of time awake.”he said.One survey showed that people who habitually_____each night have a higher risk of dying.A: fall asleep againB: become more energetic the following dayC: sleep less than 7 hoursD: confirm those serious consequencesE: suffer sleep problemsF: sleen more than 8 houlrs

考题资料：Are walkers smarter than drivers? A report published last month says metropolitan areas in the United States that were found to be more pedestrian-friendly also often had higher levels of GDP -and their citizens were better educated. The study was conducted by Smart Growth America, an urban advocacy group based in the District of Columbia. It looked at the 30 biggest metro zones in the US, and ranked them by how much office, retail, and residential area was conducive to walking. The question is, why? Do brainier people just like to walk and not drive? It's a complicated answer. What we don't know is whether walkable places attract educated people, or whether educated people move to certain places that then become more walkable. That's not all: Education levels aren't just higher in walkable cities. GDP is, too. The gap between the highest and lowest urban metros by GDP in the study is a chasm of 49%, which scholar calls a "first and second world gap. This is serious stuff." Of course, correlation doesn't equal causation. There's not enough data to definitively say why these urban areas are filled with educated people. But it's definitely a starting point for conversation: Many socioeconomic and generational trends the world over could help explain why university graduates gravitate toward crowded, subway-lined metropolises these days. In fact, such an intellectual influx has started to change the entire faces of some urban areas. Increased urbanization isn't the only reason car-eschewing cities see smarter citizens. Young people play a role, too. Millennials-those born between around 1981 and 1996-are the most educated generation in history. Nearly half of them hold a bachelor's degree or higher. They're also all moving to cities, unlike their parents. These spikes in the workforce translate into metros with higher GDP and higher overall education levels. What the positive roles played by young people?A.They put forward proposals for using public transportation rather than private cars. B.They realize their parents' dream of moving to cities. C.Their workforce leads to cities with higher GDP and educational levels. D.They contribute to cities' educational industry.

考题共用题干 Cities“Worse to Live in Than 20 Years Ago”One thousand people were surveyed about a range of issues which affect cities,and the re-markable findings show that life in today's mega-cities is so stressful that at least two-thirds of those currently living in big cities would like to relocate to the countryside or a small town.The stress of the getting from A to B in big cities is at the top of the list of problems.For many people,the daily commute to work is a source of frustration.40% of the people in the sur-vey have suffered from road rage while stuck in traffic on the way to work.The cost of public transport is also a serious problem.Many people think the price of underground and bus travel is too high and that they have to devote more than 10% of their salary to transport costs.The general cost of living in cities is another problem.The high property prices in most big cities put buying a property out of reach of most first-time buyers.Many young people are priced out of the housing market,and have to take in lodgers to make ends meet,or rent over-priced flats miles away from the city centre .In London,for instance,the price of buying even a one-bedroom flat is so prohibitive that many have given up even considering putting money aside for a deposit.Another issue facing people who live in cities is rising crime.Crime rates have rocketed in many big cities,and many say there are several dangerous no-go areas in their city.Fear of crime is on the increase-street crimes,such as mugging and assault,are now very common-and many are afraid of going out at night alone.Many were also concerned by the lack of green spaces and play facilities for children.Most major conurbations（有卫星城的大都市）surveyed have a far smaller number of parks and gar- dens than a generation ago.Planning permission seems to have been given for an ever-greater number of supermarkets,office developments and apartments on sites where there were previously green spaces.Many of the respondents in the survey said they felt stressed and suffocated in the city,a problem which is compounded by pollution.And finally,the majority of people in the survey were fed up with the constant noise pollu-lion—the roar of traffic , the sound of loud music blaring（发刺耳声）out of a neighbour's win-dow,and the constant sound of activity.It is not surprising,then,that the levels of stress-related illnesses among people who live in cities are higher than ever before .Big cities,once a mecca for ambitious people seeking fameJ and fortune,are now less and less popular among people of all ages .Perhaps the 21st century is set to be the century of the small town and the countryside. There are fewer green areas in cities than there used to be.A: RightB:WrongC: Not mentioned

考题共用题干第一篇The Relationship between IQ and Being a VegetarianA Southampton University team found that people who were vegetarians (素食主义者）by 30 had recor-ded five IQ points higher on average at the age of]U.Researchers said it could explain why people with a higher IQ were healthier as a vegetarian diet was linked to lower heart disease and obesity（肥胖）rates.The study of 8,179 people was reported in the british Medical Journal.Twenty years after the IQ tests were carried out in 1970,366 of the participants said they were vegetarians一 although more than 100 reported eating either fish or chicken.Men who were vegetarians had an IQ score of 106,compared with 101 for non-vegetarians;while female vegetarians averaged 104,compared with 99 for non-vegetarians.There was no difference in the IQ scores between strict vegetarians and those who said they were vegetarians but reported eating fish or chicken.Researchers said the findings were partly related to better education and higher class,but it remained statistically significant after adjusting for these factors.Vegetarians were more likely to be female,to be of higher social class and to have higher academic or vocational qualifications than non-vegetarians.However,these differenIces were not reflected in their annual income,which was similar to that of non-vegetarians.Lead researcher Catharine Gale said,"The findings that children with greater intelligence are more likely to report being vegetarians as adults,together with the evidence on the potential benefits of a vegetarian diet on heart health,may help to explain why a higher IQ in childhood or adolescence is linked with a reduced risk ofcoronary heart disease in adult life."But Dr Frankie Phillips of the British Dietetic Association said, "It is like the chicken and egg."Dopcople become vegetarians because they have avery high IQ or is it just that they are clever enough to bemore aware of health issues?It was found in the research that______________.A:most of the participants became vegetarians 20 years after the IQ tests were carried out B:vegetarians who ate fish or chicken were of similar intelligence with strict vegetariansC:female vegetarians were more likely to have higher annual income than non-vegetariansD:vegetarians were more likely to have higher annual income than non-vegetarians

考题 At the University of Kansas art museum,scientists tested the effect of different colored walls on two groups of visitors to an exhibit of paintings.For the first group the room was painted white;for the second,dark brown.Movement of each group was followed by an electrical equipment under the carpet.The experiment showed that those who entered the dark brown walked more quickly,covered more area,and spent less time in the room than people in the white one.Dark brown made people more active,but the activity ended sooner.Not only the choice of colors but also the general appearance of a room affects those inside.Another experiment presented people with photographs of faces whose energy was to be commented.Three groups of people were used;each was shown the same photos,but each group was in an ordinary room—a nice office.The third was in a tastefully designed living room with carpeting.Results showed that the people in the beautiful room tend to give higher marks to the faces than those in the ugly room did.Other studies that students do better on tests taken in comfortable room than in ordinary-looking or ugly rooms. Which of the following is the best expression of the main idea of this passage A.People in beautiful rooms tend to give higher marks to photos of faces than people in ugly rooms B.The color and general appearance of a room have a deeper effect on the behavior of the people in it C.The University of Kansas has studied the effects of the color of room on people’s behavior D.Beautifully furnished,light-coloured rooms make people more comfortable than ugly,dark rooms

考题 The number of speakers of English in Shakespeare’s time is estimated (估计) to have been about five million. Today it is estimated that some 260 million people speak it as a native language, mainly in the United States, Canada, Great Britain, Ireland, South Africa, Australia and New Zealand. In addition to the standard varieties of English found in these areas, there are a great many regional and social varieties of the language as well as various levels of usage that are employed both in its spoken and written forms. In fact, it is impossible to estimate the number of people in the world who have acquired an adequate (足够的) working knowledge of English in addition to their own languages. The purpose for English learning and the situations in which such learning takes place are so varied that it is difficult to explain and still more difficult to judge what forms an adequate working knowledge for each situation. The main reason for the widespread demand for English is its present-day importance as a world language. Besides serving the indefinite needs of its native speakers, English is a language in which some of important works in science, technology, and other fields are being produced, and not always by native speakers. It is widely used for such purposes as meteorological and airport communications, international conferences, and the spread of information over the radio and television networks of many nations. It is a language of wider communication for a number of developing countries, especially former British colonies. Many of these countries have multilingual populations and need a language for internal communication in such matters as government, commerce, industry, law and education as well as for international communication and for entrance to the scientific and technological developments in the West.Which of the following statements is NOT true A、Some 260 million people in the world have an adequate working knowledge of English.B、There are some 260 million native speakers of English in the world.C、It is almost impossible to estimate the number of people with an adequate working knowledge of English.D、People learn English for a variety of reasons.
