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, it 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 no TV in the bedroom and also a home computer to use.
