学案(三)　高考语篇的价值发掘——提升学科素养
2017·浙江6月高考·阅读理解B篇——对接课标主题：健康的生活方式、积极的生活态度
Getting less sleep has become a bad habit for most American kids. According to a new survey (调查) by the National Sleep Foundation, 51% of kids aged 10 to 18 go to bed at 10 pm or later on school nights, even though they have to get up early. Last year the Foundation reported that nearly 60% of 7- to 12-year-olds said they felt tired during the day, and 15% said they had fallen asleep at school.
How much sleep you need depends a lot on your age. Babies need a lot of rest; most of them sleep about 18 hours a day! Adults need about eight hours. For most school-age children, ten hours is ideal (理想的). But the new National Sleep Foundation survey found that 35% of 10- to 12-year-olds get only seven or eight hours. And guess what almost half of the surveyed kids said they do before bedtime Watch TV.
“More children are going to bed with TVs on, and there are more opportunities (机会) to stay awake, with more homework, the Internet and the phone，” says Dr. Mary Carskadon, a sleep researcher at Brown University Medical School. She says these activities at bedtime can get kids all excited and make it hard for them to calm down and sleep. Other experts say part of the problem is chemical. Changing levels of body chemicals called hormones not only make teenagers' bodies develop adult characteristics, but also make it hard for teenagers to fall asleep before 11 pm.
Because sleepiness is such a problem for teenagers, some school districts have decided to start high school classes later than they used to. Three years ago, schools in Edina, Minnesota, changed the start time from 7：25 am to 8：30 am. Students, parents and teachers are pleased with the results.
