     Air is a colorless, tasteless and invisible (无形的)  gas that is around us. An"empty" drinking glass
and an"empty"room,in fact,are not really empty. Each is filled with air. When the glass is filled with
water, the water pushes the air out of the glass.
     Air, as a gas, has no definite (确切的) shape, but because it is matter, it takes up space and it has
weight. It is easy to prove (证明) that air is something that takes up space. Stuff a piece of dry cloth
into the bottom of a glass so that it will not fall out when the glass is turned upside down. Push the
upside-down glass,holding it straight up and down, into a jar of water till the glass is completely covered.
When the glass is taken out of the water, the cloth is still dry. The air inside the glass shows that it takes
up space and keeps the water from coming in.

A rich man was ill in hospital, and the doctor feared that his life was ending soon. He called together his three sons and gave them the challenge, ‘One of you will get all my money. To decide which of you can get the money, I am going to give each of you a dollar. Go today and buy something that can fill this room.”
