What is the sky?①This question is very difficult to answer.The sky is a space where there is nothing except the sun,the earth,the moon and all the stars.

Scientists can look at them through telescopes(望遠(yuǎn)鏡) and,in this way,they can find out a great deal (許多,大量).They know many facts about the moon.For example,they know how big and how far away it is.②The moon is about 384,000 kilometers away from the earth.A plane cannot fly to the moon because there is no air.But a rocket can.

“How can 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 it go!The balloon will fly off through the air very quickly.The air inside the balloon tries to get out through the neck of it,which pushes(推動)the balloon through the air.It does not need wings(翅膀)like a plane.③.Of course,the rocket is made of(由……制成) metal(金屬).The metal must not be heavy but it must be very strong.There is a gas(氣體) inside the rocket which is made very hot.When it rushes out of the rocket,the rocket is pushed up into the air.
