    Rockets in the Sky
    If someone asked you,"What color is the sky?"I expect that you would answer,"Blue."I am afraid that you would be wrong.The sky has no color.When we see blue,we are looking at blue sunlight.The sunlight is shining on little bits of dust in the air.
    We know that there is air all around the world.We could not breathe without air.Airplanes could not fly without air.They need air to lift their wings.Airplanes cannot fly very high because as they go higher the air gets thinner.If we go far enough away from the earth,we find there is no air.
    What is the sky?The sky is space.In this space there is nothing except the sun,the moon and all the stars. Scientists have always wanted to know more about the other worlds in the space.They have looked at them through telescopes and in this way they have found out a great deal.The moon is about 384 ,000 kilometers away from the earth.An airplane cann't fly to the moon but there is a thing that can fly even when there is no air. This is rocket.
    I am sure that you are asking,"How does a rocket fly?"If you want to know,get a balloon and then blow it up until it is quite big.Do not tie up the neck of the balloon.Let go!The balloon will fly off through the air very quickly.The air inside the balloon tries to get out.It rushes out through the neck of the balloon and this pushes the balloon through the air.It does not need wings like an airplane.
    This is how a rocket works.It is not made of rubber（橡胶）like a balloon,of course.It is made of metal. The metal must not be heavy but it must be very strong.There is gas inside the rocket which is made very hot. When it rushes out of the end of the rocket,the rocket is pushed up into the air.
    Rockets can fly far out into space.Rockets with men inside them have already reached the moon.Several rockets,without men inside them,have been sent to other worlds much farther away.One day rockets may be able to go anywhere in the space.

    A rocket can fly to the moon because______.
    A:it looks like a balloon
    B:it is much lighter than an airplane
    C:it doesn't have wings
    D:it works like an untied balloon

    答案：D
    解析：
    根据第一段第四句可知，天空没有颜色。
    根据第二段第五句“Airplanes cannot fly very high because as they go higher the air gets thinner.”可知，由于位置越高，空气越稀薄，飞机飞不了太高。
    根据第五段可知，火箭飞行的原理与没扎口的膨胀的气球相似。
    根据第六段最后一句“When it rushes out of the end of the rocket , the rocket is pushed upinto the air.”可知，火箭是由热气流高速向后喷出所产生的反作用力来推动的，而不是由内部燃烧的气体推动的。
    根据第六段最后一句可知，当热气从火箭尾部冲出时，火箭被送人空中。C项中的“itsbottom”是第六段最后一句中的“the end of the rocket”的同义转换。

    B:It can fly without wings.
    C:It is made of strong metal.
