It is important for each child to get enough sleep every day. Here. we'll learn more about that.

    It usually depends on(取决于) their age. Newborns of o to 3 months should sleep for about 18 hours a day. Babies of 4 to 11 months should start to sleep through the night, for 9 to 12 hours at a time. Children of 3 to 5 years should get 11 to 13 hours a day. Children of 6 to 13 need 9 to 11 hours of sleep. Teenagers(青少年) of 14 and up need 8 to 10 hours of sleep.

    Set a strict nap timetable(小睡时间表). Younger children should take a short sleep during the day. Even older children can benefit(获益) from late-afternoon naps if they don't get enough sleep at night. 

    Pay attention to screen time. Remember to ask children to tum off the television and the computer an hour before they go to bed. If possible, get them out of their bedrooms since the light from the screens can make sleep a difficult job. 

    Get children moving. Running around and playing sports are great, but children can move in other ways too. They can take a dog for a walk or go to the park-just get them out of the house and get them moving. 

    A little girl heard her parents talking about her brother. All she knew was that he was sick and they had no money. Only a very1operation could save him but there was no one to2them the money any more.

    "What do you want?" asked the salesman. "It's for my brother," the girl answered. "He's really, really sick and I want to buy a miracle." "5?" asked the salesman.

    "My brother Andrew has something bad6inside his head and my daddy says only a miracle can save him. So how much is a miracle? ""We don't sell a miracle here, child. I'm very7, "the salesman said with a smile.

    "Listen, if it isn't enough, I can return and get some more. Just tell how much it 8. "

    A well-dressed man heard it and asked," What kind of miracle does your brother 9?"

    "An operation!" she answer Ed with her Eyes full of tears. "But my daddy can't 10it, so I have brought all my money."

    "How much do you have?" asked the gentleman. "$1.11, but I will11to take more," she answered.

    "Well, what a piece of12!" smiled the man. "$1.11, the price of a miracle for your little brother,"

    He took up the girl's hand and said, "Take me to your13. I want to see your brother and your parents. Let's14if I have the kind of miracle your brother needs. "

    This story is about a young man. He worked very hard at his lessons. He was too busy to have a rest. Ashe became ill, he couldn't go to sleep. Every night, when he went to bed, he closed his eyes and tried to sleep. But the more he tried, the more he stayed awake.

    After a while he decided to visit the doctor, "I just can't go to sleep at night. What shall I do? "

    "I have a suggestion," said the doctor. "Try counting numbers. By the time you reach one thousand, you'll be asleep. I am sure of it."

    The next day the man returned to the doctor's office. "Well," said the doctor, "How are you today? Did you try my suggestion?"

    The man still looked tired. "Yes, "he said, "I tried counting one, two, three…up to one thousand. But when I reached five hundred and sixty-nine, I began to feel sleepy. I had to get up and drink some tea so that I could go on counting up to one thousand. But then I still couldn't fall asleep. "
