Do you know how much your children sleep?
According to the National Sleep Foundation,       should sleep twelve to eighteen hours       of every twenty-four. With a gradual        to twelve to fourteen hours for toddlers(初学走路的孩子) one to three; eleven to thirteen hours for        three to five; and ten to eleven hours for schoolchildren        five to ten.
But things get really      at adolescence. Not only do teenagers need more sleep than    __---eight and a half to nine and a quarter hours a night, according to the sleep foundation - but the times          which they get sleepy and are able to awaken         and feel rested shift in a       that does not match to the       times at most schools.
Sleep studies have shown that the typical teenager does not fall asleep readily before 11 p. m. or later.       many have to get up by 6 a. m. or         to get to school for a class         starts at 7:30 or 8 a.m. More than a few        off during that class, and often the         one as well. Even if awake, they're in no condition to learn much of anything.
In one study, more than 90 percent of teenagers        they slept less than the          nine hours a night, and 10 percent said they slept less than six hours.
      _ James B. Maas, a Cornell University psychologist and Leading sleep researcher, has observed, most teenagers are "walking zombies(僵尸)"        they get far too little sleep.
