    On 19th September 1783, Pilatre De Rozier, a scientist, sent the first hot air balloon. The passengers were three animals and the balloon stayed in the air for about 15 minutes before hitting back to the ground.

    The first manned(载人的) flight was about 2 months later, with a balloon made by 2 French brothers. The balloon flew for a period of 20 minutes.

    Sailing through the sky in the balloon, high above buildings and trees, you can't feel or hear the wind because you're traveling in the same direction and at the same speed as it is.

    A hot air balloon has three main parts: the balloon, called an envelope; a basket, where passengers ride; and a burner system, which supplies the hot air.

    Most balloon envelopes are made of strong, lightweight nylon(尼龙). They are different in size and shape, but they have to be really, really big to lift even one person. Most weigh more than an adult man.

    The basket is usually made of wicker(柳条), which is strong but not too hard. It needs to bend a bit for a soft landing, just like a good jumper bends her legs instead of keeping them straight when she lands.

    The hot air balloon works on the theory that hot air rises faster than cooler air. When the burner system is turned on, it makes a noisy sound, but once the balloon is flying, the burner can be turned off. The air in the envelope will then cool, and the balloon will slowly go down unless the pilot starts the burner system again.

    To control a hot air balloon, a pilot adds hot air to it to go up or lets the air out to go down until he finds a wind blowing in the direction he wants to fly. But no matter which way the wind blows, the passengers have an amazing bird's-eye view of the world.

    December 21 was Becky's fourteenth birthday. When she got home after school, she saw her parents in the living room. They said to her, "Happy birthday, dear! We have a present for you, Becky. Go and look for it in your bedroom."

    Becky ran quickly to her room. On her bed she saw a bright red box. She thought that her present must be in the box. She opened it. There was nothing but a card in it. The girl took it out and read.

    "Dear Becky, I'm your present. My first three letters are the same as in the word 'come'. My last two letters are the same as in the word 'water'. My middle three letters are in the word 'put'. What am I?"

    Becky thought hard and soon smiled. She then went back to the living room and shouted. "Aha, I know what present it is. Thank you very much, Mum and Dad! But where is it?" Her mother answered, "Look at the back of the card." Becky turned it over and read, "Come and look for me in the study."

    Becky hurried to the study. There on the desk she found her present. What was it? Do you know?
