问题     Too much television can be detrimental for kids’ development, even when they’ re not plopped directly in front of the screen. And your kids might be getting more exposure to such background TV than you think, a new study finds.
    The researchers found that the average American kid was exposed to 232.2 minutes of background television per day—when the TV was on, but the child was engaged in another activity. Younger children and African-America children were exposed to the most background television on average.
    "We were ready and willing to accept that the exposure would be high, but we were kind of shocked at how high it really was," says study author Matthew Lapierre, a doctoral candidate and lecturer at the University of Pennsylvania’ s Annenberg School for Communication. "The fact that kids are exposed to about four hours on average per day definitely knocked us back on our heels a bit."
    Previous research has found that exposure to background television is linked to lower attention spans, fewer and lower-quality parent-child interactions and reduced performance in cognitive tasks, the authors said in the study.
    The current findings came from data gathered in a nationally representative telephone survey of 1,454 American parents with at least one child between the ages of 8 months and 8 years. The parents were asked about how often their TV was on when no one was watching and whether their child had a TV in their bedroom.
    "For every minute of television to which children are directly exposed, there are an additional 3 minutes of indirect exposure, making background exposure a much greater proportion of time in a young child’s day," the authors say in the study.
    What they found even more concerning was that kids under 2 and African-American children are exposed to 42% and 45% more background TV, respectively, than the average child.
    "It’s particularly concerned because there is an evidence this exposure has negative consequences for development," says Lapierre. According to the authors, these high rates could be the result of parents not counting background TV as exposure or thinking their kids are too young to be affected by it.
    "This study should be a warning to parents and day-care providers to shut off the television when no one is watching, and certainly to consider the consequences of having a television in a child’ s bedroom no matter how young they may be," said Cynthia Stohl, the International Communication Association president and professor of communication at the University of California, Santa Barbara, in a statement.
    The researchers are hopeful their findings will further the understanding of how home media practices relate to background television exposure, so recommendations for reducing kids’ exposure can be made.
According to the study, the exposure to background television does NOT result in______.
选项 A、less concentration
B、lower interactions between parents and children
C、poor eye sight
D、inadequacy in learning tasks
答案C
解析 细节题。题干问，根据研究表明长期暴露在电视前不会导致的情况。定位于原文第四段，选项A对应“lower attention spans”；选项B对应“fewer andlower-quality parent-child interactions”；选项D对应“reduced performance in cognitivetasks”。选项C，视力下降，是干扰项。此处注意，虽是常识，但并没有在文中提及。所以不能作为其后果。故选C。
