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

共用题干Teaching Math,Teaching AnxietyIn a new study about the way kids learn math in elementary school,the psychologists at the University of Chicago Sian Beilock and Susan Levine found a surprising relationship between what female teachers think and what female students learn:If a female teacher is uncomfortable with her own math skills,then her female students are more likely to believe that boys are better than girls at math.If these girls keep getting math-anxious female teachers in later grades,it may create a snowball effect on their math achievement said Levine. In other words,girls may end up learning math anxiety from their teachers. The study suggests that if these girls grow up believing that boys are better at math than girls are,then these girls may not do as well as they would have if they were more confident.Just as students find certain subjects to be difficult,teachers can find certain subjects to be difficult to learn一and teach. The subject of math can be particularly difficult for everyone. Researchers use the word“anxiety”to describe such feelings:anxiety is uneasiness or worry.The new study found that when a teacher has anxiety about math,that feeling can influence how her female students feel about math. The study involved 65 girls,52 boys and 17 first-and second-grade teachers in elementary schools in the Midwest. The students took math achievement tests at the beginning and end of the school year,and the researchers compared the scores.The researchers also gave the students tests to tell whether the students believed that a math superstar had to be a boy. Then the researchers turned to the teachers:To find out which teachers were anxious about math,the researchers asked the teachers how they felt at times when they came across math,such as when reading a sales receipt. A teacher who got nervous looking at the numbers on a sales receipt,for example,was probably anxious about math.Boys,on average,were unaffected by a teacher's anxiety. On average,girls with math-anxious teachers scored lower on the end-of-the-year math tests than other girls in the study did. Plus,on the test showing whether someone thought a math superstar had to be a boy,20 girls showed feeling that boys would be better at math一and all of these girls had been taught by female teachers who had math anxiety.“This is an interesting study,but the results need to be interpreted as preliminary and in need of replication with a larger sample,”said David Geary,a psychologist at the University of Missouri in Columbia.David Geary thinks that______.A: the study is interesting but it is based on unreliable research processB: the research results need to be retested based on a larger sampleC: the research results need to be reinterpreted to be meaningfulD: the study is well based and produces significant results
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、neutralB、criticalC、ndifferentD、biased

共用题干Food and CancerMedical experts have suspected for many years that there is a strong link between what a person eats and cancer. They say a new study provides the first evidence that vitamins could reduce a person's chance of developing cancer. A team of Chinese and American scientists did the study.They are from American National Cancer Institute and the Cancer Institute of the Chinese Academy of Medical Sciences in Beijing. The Journal of the National Cancer Institute published the results of the study. About thirty thousand people between the ages of 40 to 69 took part in the study.They were from the northern central Chinese area of Linxian.Most of them took vitamins and minerals everyday for five years.Linxian was chosen because the people there have an extremely high rate of cancer of stomach and esophagus.Researchers believe that fungus and molds in local foods may be partly responsible for the high cancer rate.Researchers divided those people into eight groups.Seven of the groups received different mixtures of vitamins and minerals daily.The amounts of the vitamins and minerals were 1 to 2 times greater than what American health officials say is needed.The eighth group received sugar pills that had no effect.Those who seemed to gain the most received a mixture of a form of vitamin A called β-carotene,vitamin E and the mineral selenium（硒）.The vitamin and mineral are believed to prevent damage to cells caused by cancer-causing substances.Researchers reported a 1 3 percent drop in cancer rates in those who took β-carotene,vitamin E and selenium.They also found a 10 percent drop in the number of deaths caused by strokes from bursting blood vessels.Scientists warn that it is too soon to know if the effect would be the same among people in other countries.They note that the people in Linxian eat foods that lack necessary vitamins and minerals.Chinese officials will continue to record the health records of the people in Linxian for many years.For now officials reportedly are considering using the results of the study.They want to find a way to improve the health of people in Linxian and other small towns in China. The rate of cancer of stomach and esophagus in Linxian is the highest in China.A:RightB:WrongC:Not mentioned
