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 bedroom 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 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 shouldn’t have TVs in their bedrooms.
1.According to the California study,the low-scoring group might .
A.have watched a lot of TV
B.not be interested in math
C.be unable to go to college
D.have had computers in their bedrooms
答案:A
解析:推理判断题。第二段中对加利福尼亚北部400名三年级学生的研究发现,卧室里有电视的学生要比卧室里没有电视的学生考试分数低8分左右。据此推断考试分数低的原因可能是看电视太多。故选A项。
2.What is the researchers’ understanding of the New Zealand study results?
A.Poorly motivated 26-year-olds watch more TV.
B.Habits of TV-watching reduce learning interest.
C.TV-watching leads to lower education levels of the 15-year-olds.
D.The connection between TV and education levels is difficult to explain.
答案:D
解析:细节理解题。根据第三段最后一句话可知,对大约1000名新西兰成年人的研究结论是:教育水平低不一定是因为看电视过多,但也不能排除。据此推断观看电视和受教育的水平之间的联系很难解释。故选D项。
3.What can we learn from the last two paragraphs?
A.More time should be spent on computers.
B.Children should be forbidden from watching TV.
C.TV sets shouldn’t be allowed in children’s bedrooms.
D.Further studies on high-achieving students should be done.
答案:C
解析:细节理解题。倒数第二段提到卧室里有电视机没有电脑的孩子考试得分最低,而卧室里有电脑没有电视机的孩子得分最高;最后一段的研究结论是:这项研究虽然不能证明是卧室内的电视导致了孩子考试分数低,但为孩子卧室内不应该放有电视机增加了证据。据此判断不能在孩子卧室放有电视机。故选C项。
4.What would be the best title for this text?
A.Computers or Television
B.Effects of Television on Children
C.Studies on TV and College Education
D.Television and Children’s Learning Habits
答案:B
解析:主旨大意题。第一段指出,几项有关电视对孩子的影响的研究结果表明:看电视过多会对孩子的学习能力造成危害,甚至会减少孩子升入大学的机会。随后几段分别对几项具体调查研究进行陈述,并针对观看电视与考试成绩、教育水平之间的因果关系分别得出几个不同的结论。概括全文可知本文主要讲述的是电视对孩子的影响。故选B项。
