单选题 Dina Borzekowski made a study of a group of third grade
students from six American schools. During a school year, nearly 400 students
and their parents were asked to report on whether they had such things as
televisions and computers in the home, as well as how often the child used them.
The children's language ability was tested (测验) twice over the year. Children
who had a television set in the bedroom but did not have a computer at home
scored （得分) the lowest, while students without TV in the bedroom but with a
computer at home scored the highest. Students who had a television in the
bedroom over the school year scored lower than those who had their TV taken away
during the same time. "This study suggests that taking TV sets
out of children's bedrooms, or not putting them there, may be helpful," said
Borzekowski, "While this study does not prove (证明) that bedroom TV was the
reason for the lower test scores, {{U}}it{{/U}} suggests that children shouldn't
have TV in their bedrooms. It also suggests that a home computer may help a
child's test scores. The best way was having both: no TV in the bedroom and also
a home computer to use."
