You may know about “ junk food” like French fries. But do you know about “junk sleep”?

    Recently, a British survey found that electronic(电子) products in teenagers bedrooms are affecting(影响)their sleep.

    The survey was done among 1,000 British kids from 12 to 16. It found that percent of them got just 4 to 7 hours sleep every day. But doctors say they need 8 to 9 hours.

    Almost a quarter of the kids said they fell asleep more than once a week while watching TV, listening to music or using other electronic products.

“This is very worrying.” Said Dr Chris Idzikowski, a British expert, “We call it ‘junk sleep’, It means you don’t get enough sleep and the quality of the sleep is bad, too. If you don’t get good rest, you don’t perform well in school the next day.”

The survey found that 40 percent of the kids felt tired each day, with girls between 13 and 16 feeling the worst. Nearly all the teenagers have a phone, Mp4 or TV IN THEIR BEDROOM. And many of them have all three.

Television has taken the place of schools as the main educator(教育者) in America. There are several reasons for this. First, there is the number of hours. While Americans spend about 13,000 hours in schools, they spend 15,000 to 16,000 hours in front of a TV set. Second is the age at which viewers(观看者) start watching TV. People start watching and understanding TV at about the age of 3, which is several years before they start to do school work. Finally, there is the number of viewers. About 90,000,000 young people are attending school, but most of the Americans watch TV every day. It seems, then, that TV shows are taking the place of teachers and professors as the educators in America.
