The survey was done {#blank#}2{#/blank#}(在……之中) 1,000 British kids from 12 to 16. It found that 50% of them got just 4 to 7 hours' sleep every day. But doctors say they need 8 to 9 hours. Almost 25% of the kids said they often fell asleep while they were {#blank#}3{#/blank#}(看) TV, listening to music or using other electronic products.
"This is very worrying," said Dr. Chris, a British professor, "We{#blank#}4{#/blank#}(把……叫做) it ‘junk sleep'. It means you don't get {#blank#}5{#/blank#}(充足的) sleep and the quality of the sleep is low, too. If you don't get a good {#blank#}6{#/blank#}(休息), you can't listen to the teachers carefully in class the next day."
The survey found that quite a few of the kids felt {#blank#}7{#/blank#}(疲倦的) each day, especially girls between 13 and 16 feeling the worst. Junk sleep is the most important {#blank#}8{#/blank#}(原因). Nearly all the teenagers have a phone, MP5 or TV in their bedrooms. And lots of them even have all the three.
Dr. Chris suggested that {#blank#}9{#/blank#}(父母) should help their children keep away from electronic products, and teenagers should spend {#blank#}10{#/blank#}(更少的) time on the electronic products.
