Question

Do you know how much your children sleep?

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.

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.
