     Do you sometimes put off doing your homework on a school night to watch TV? A new study says that

middle school students who watch TV or play video games during the week do worse in school. The study

also says that watching TV and playing video games on weekends don't affect school performance that much.

     "They could watch a lot on weekends and it didn't seem to connect with doing worse in school," said Dr.

Iman Sharif of Children's Hospital at Montefiore in New York. The study appears in the October issue of

Pediatrics. Researchers drew their conclusions after surveying (调查) 4,500 students in New Hampshire and

Vermont middle schools.

     To reach their findings, researchers didn't look at grades or test scores. Instead, they asked students to

rate their own performance on a scale ranging from "excellent" to "below".

     Other studies have found a connection between kids' ability to learn and the amount of TV they watch.

One study even found that kids with televisions in their bedrooms scored about eight points lower on math

and language arts tests than kids without them.

     What should a kid do? The American Academy of Pediatrics recommends (推荐) that kids watch TV

no more than two hours and that televisions be kept out of children's rooms. Weekend viewing should be

kept to four hours at most each day.
