A
Air is an odorless(that cannot be smelled;smelless),invisible(that cannot be seen)gas that surrounds the planet earth.It is everywhere on the planet.An “empty” drinking glass and an “empty” room,to give two examples,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(fixed,particular)shape,but,because it is matter,it takes up space.It is easy to prove that air is something that takes up space.Stuff a dry handkerchief 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,hold it straight into a jar of water till the glass is completely covered.When the glass is taken out of water,the handkerchief will be dry.The air inside the glass took up space and kept the water from coming in.
1.“Stuff a dry handkerchief into…”.The underlined word means.
A.Press tightly     B.Take out          C.Put down     D.Turn fully
