考题 C Too much TV-watching can harm childrens ability to learn and even reduce their chances of getting a college degree, new studies suggest in the latest effort to examine the effects of television on children.One of the studies looked at nearly 400 northern California third-graders. Those with TVs in their bedrooms scored about eight points lower on math and language arts tests than children without bedrooms TVs.A second study, looking at nearly 1,000 grown-ups in New Zealand, found lower education levels among 26-year-olds who had watched lots of TV during childhood. But the results dont prove that TV is the cause and dont rule out that already poorly motivated youngsters(年轻人)may watch lots of TV.Their study measured the TV habits of 26-year-olds between ages 5 and 15. Those with college degrees had watched an average of less than two hours of TV per weeknight during childhood, compared with an average of more than 2 hours for those who had no education beyond high school.In the California study, children with TVs in their rooms but no computer at home scored the lowest, while those with no bedroom TV but who had home computers scored the highest.While this study does not prove that bedroom TV sets caused the lower scores, it adds to accumulating findings that children shouldnt have TVs in their bedrooms.第64题：According to the California study, the low-scoring group might____________.A. have watched a lot of TVB. not be interested in mathC. be unable to go to collegeD. have had computers in their bedrooms

考题 If you use your commute to catch up on work email, that time "should be counted as part of the working day," according to a new study by researchers who analyzed thousands of commuters'online habits." If travel time were to count as work time, there would be many social and economic impacts." said Juhet Jain, one of the academics from the University of the West of England who surveyed several thousand commuters on trains in and out of London. "Most respondents expressed how they consider their commute as time to 'catch up' with work, before or after their traditional working day," according to a summary of the study.“This transitional time also enabled people to switch roles, for example from being a parent getting the kids ready for 3 school in the morning to a business director during the day " The study quotes a working mother named Katheryn saying. "It's really important to my sanity that I can get work done on the tram. I am a busy mum and I rely on that time, so I can get things done”Another commuter, Andrew, told the researchers.'“It's dead time in a way so what it allows me to do is finish stuff and not work in the evenings." The study notes that while work rules vary around the world, some commuters in Norway are already "able to count travel time as part of their working day” The findings on workers' use of smartphones and other devices to stay plugged in highight the importance of providing Wi-Fi to commuters, according to the academics, who presented their study at the Royal Geographical Society. To ollet the data, they focused on two train lines that boosted the amount of free Wi-Fi they offered. On the Birmingham to London line, 60 percent of commuters connected to the enhanced network. The results hint at what are likely to be increasingly complicated work-life discussions, in which employees and their bosses debate what qualifies as "work" and where the line between personal and professional time should be drawn. Discussing the results in a news release, Jain said, "It may ease commuter pressure on peak hours and allow for more comfort and flexibility around working times. However, it may also demand more survillance and accountability for productivity." In addition to potential ramifications for mass transit that the British researchers highlighted,the idea of claiming commuting time on the clock could also appeal to workers who use other means of travel. Take, for instance, people who rely on ride. share companies to get to their jobs. And the discussion seems certain to widen in the near future, to inc lude a looming wave of self-driving cars that - in theory, at least -promises to free up more travel time for drivers. As for rail commuters, the researchers said their work shows it s important that trains "“ffer a good working environment including tables , power。space and good continuous connectivity for internet and phone calls" what is the author' s attitude towards the study ? A、neutral B、critical C、ndifferent D、biased

考题资料：The increasing amount of personal information that can be collected by computer programs that track how people use Facebook has been revealed by an extensive academic study. Such programs can show undisclosed private information such as Facebook users' sexuality, drug-use habits and even whether their parents separated when they were young, according to the study by the University of Cambridge academics. In one of the biggest studies of its kind scientists from the university’s team and a Microsoft-funded research center analyzed data from 58,000 Facebook users to predict traits and other information that were not provided in their profiles. The algorithms were 88 per cent accurate in predicting male sexual orientation, 95 per cent for race and 80 per cent for religion .And political leanings, personality types and emotional stability were also predicted with accuracy ranging from 62-75 per cent. The study highlights growing concerns about social networks and how data trails can be mined for sensitive information even when people attempt to keep information about themselves private ：Less than 5 per cent of users were connected with explicitly gay groups. Michal Kosinksi ，one of the report’s authors told the Financial Times that the university’s techniques could easily be replicated by companies to inter personal attributes a person did not wish to share such as sexual orientation or political views:”We used very simple and generic methods :Marketing companies and internet companies could spend much more time and resources and hence get much higher accuracy than we did. The report also revealed some unexpected correlations such as people who liked ‘curly fries’ having higher IQs while those Who like Facebook’s “Sliding on Floors With Your Socks On”page were unlikely to use drugs. According to Michal Kosinksi,which of the following is true according to the passage?A.The study draws people’s attention for private information B.information can be predicted correctly in the study C.some personal information may be collected and used by some companies D.if people attempt to keep personal information private, things will change

考题单选题Passage1Children who spend more than two hours a day at a computer or watching television are more likely than others to have mental problems，scientists say.Researchers found that 11-year-olds who spent several hours in front of a screen each day did worse on mental health tests，no matter how much physical exercise they got. The University of Bristol study，published in Pediatrics，involved more than 1，000 children aged about 10.They also had the kids fill out questionnaires designed to gauge the kids' emotional well-being and behavior.The questionnaires contained 20 questions covering five sections-emotional difficulties，conduct problems，hyperactivity or inattention，friendships and peer groups and problems relating to friends and peer groups.The study found no direct evidence that sitting in front of a screen actually causes mental health problems. Instead，it suggests that children with difficulties，such as extreme shyness，are more likely to choose TV or computer games than sociable activities. In the study，children were asked whether they agreed，disagreed or somewhat agree with a list of statements，including，"I generally play alone or keep to myself" and，"I am often unhappy or tearful".They were also asked how much exercise they took and how long they spent at a TV or computer screen.According to the study，children who spent more than two hours a day at a screen had a 60% higher risk of mental problems than children who spent fewer viewing hours. The risk was only slightly higher in children who did little or no exercise."Physical activity is good for health in many ways，but it can't make up for long hours of screen viewing. Parents should consider limiting their children's screen viewing to no more than 2 hours a day，”said the study organizer，Angie Page.Previous studies have raised concerns that watching too much television can affect children's behavior in later life. A Canadian study found that those who watched most TV as young children performed worse at school, ate more junk food and had more trouble concentrating.What is the passage mainly about?A It describes the reasons people watch television.B It reports the findings of a scientific study.C It discusses ways to improve children's physical health.D It advises parents on raising their children.
