C Too much TV-watching can harm children’s 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 don’t prove that TV is the cause and don’t 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 2½ 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 shouldn’t 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 Kicking the HabitWhat is a bad habit?The most common definition is that it is something that we do regularly,almost without thinking about it,and which has some sort of negative consequence.This consequence could affect those around us,or it could affect us personally.Those who deny having bad habits are probably lying. Bad habits are part of what makes us human.Many early habits,like sucking our thumb,are broken when we are very young.We are either told to stop doing it by our parents,or we consciously or subconsciously observe that others do not have the same habit,and we gradually grow out of it.It is when we intentionally or unintentionally pick up new habits in our later childhood or early adulthood that it becomes a problem.Unless we can break that habit early on,it becomes a part of our life,and becomes"programmed"into our brain.A recent study of human memory suggests that no matter how hard we try to change our habits,it is the old ways that tend to win,especially in situations where we are rushed,stressed or overworked.Habits that we thought we had got rid of can suddenly come back.During the study programme,the researchers showed a group of volunteers several pictures,and gave them words to associate with them.They then showed the volunteers the same pictures again,and gave them new words to associate with them.A few days later,the volunteers were given a test.The researchers showed them the pictures,and told them to respond with one of the words they had been given for each one.It came as no surprise that their an- swers were split between the first set of words and the second.Two weeks later,they were given the same testagain.This time,most of them only gave the first set of. words.They appeared to have completely forgotten the second set.The study confirms that the responses we learn first are those that remain strongest over time.We may try to change our ways,hut after a while,the response that comes to mind first is usually the first one we learned.The more that response is used,the more automatic it becomes and the harder it becomes to respond in any other way.The study therefore suggests that over time,our had habits also become automatic,learned behavior. This is not good news for people who picked up bad habits early in life and now want to change or break them.Even when we try to put new,good intentions into practice,those previously learned habits remain stronger in more automatic,unconscious forms of memory.The study suggests that it is more difficult to respond to what we learn first?A:RightB:WrongC:Not mentioned
