Is it difficult for you to get up in the morning? Are you often late for work or school? Yes? Then a scientist called Mike has a special bed for you. His Bed will get you up in the morning! Here is how it works!

    The bed is connected to an alarm clock. First, the alarm clock rings. You have a few minutes to wake up. Next, a tape recorder in the bed plays soft music and then your girlfriend's beautiful voice comes, “Wake up, darling, please.” A few minutes later, loud music comes from the tape recorder. At the same time, you may hear the voice of your boss. Your boss shouts angrily, “ Wake up at once, or you'll be late!” If you don't get up after that, you'll be sorry! A plastic “foot” is in the bed. It kicks you in the head. Then the bed waits for a few more minutes. What! You're still in bed! Slowly the top of the bed rises higher and the foot of the bed goes lower. Finally, you fall off the bed and onto the floor. You are out of the bed and awake!

    Mike made his bed because he wanted to take part in a competition. Mike won one of the top prizes for his bed.

    Children know that summer is probably the most fun of all seasons. However, experts say it is also the most dangerous, especially, for children aged 14 and under. In its first study of children's safety in the US, the National Safe Kids Campaign(NSKC) founds that nearly half of the injury-related(与受伤相关的) deaths among children happened in summer.

    Experts are not surprised by the study's results. They always know summer is a dangerous season for children. During the summer, children are out of the school and spend more time outdoors. They are more likely to get into an accident or be injured. “While we encourage children to be active and spend more time outdoors, they need to understand the importance of safety,” said Everett Koop, an expert of the NSKC.

    To help children say safe, the NSKC started a “Make it a Safe Kids Summer” campaign during National Safe Kids Week, from May 5 through May 12. Here are some important summer safety tips from the NSKC:

    Always wear your seat belt.

    Make sure there is an adult around when you decide to go swimming.

    Wear a life jacket when on a boat or doing water sports.

    Obey all traffic rules.

    There was a man    ①    had four sons. He wanted his sons to learn not to judge things too quickly. So he sent them to go and look at a pear tree far away in turns．

    The first son went in the winter, the second in the spring, the third in summer, and the youngest son in the fall    ②    they had all gone and come back, he called them together to describe    ③    they had seen. The first son said     ④    the tree was ugly. The second son said no-it was covered with green leaves and full of hope. The third son disagreed, he said there were many flowers that smelled so sweet and looked so beautiful, it was the most wonderful thing he had ever seen. The last son disagreed with all of them, he said there was lots of fruit on the tree,full of life and harvest.

    The man then explained to his sons that they were all right, but they had each seen only one season in the tree's life. He told them, "You cannot judge a tree, or a person by only one season and its true nature--the pleasure, joy, and love that come from that life can only be measured (测量)at the end, when all the seasons are up.＂

    If you give up when it's winter, you will miss the promise of your spring, the beauty of your summer, the harvest of your fall.Don't let the pain of one season kill the joy of all the rest.

    James Watt was an English boy. He liked asking questions and was always thinking hard.

    One day he was sitting in the kitchen with his grandmother. There he saw a kettle (壶) on the fire. Some steam began to come out of the kettle. The lid (盖子) was shaking. "Grandma, what's in the kettle?" he asked. "Water, my child… nothing, but water." "But I know there is something else. It pushes the lid up. How did the steam get under the lid?" "It comes from the hot water."

    The boy said to himself, "The steam must be very strong. It can push things. If there is more water, the steam will be much stronger."

    Many years later James Watt tried to make steam work for people. He gave the world the first engine.
