   What is a backyard？Many Chinese people have never seen one.In the US，however，the backyard is an important part of most homes.When an American buys a house，he or she is also buying the small space of land around it.Sometimes there's a space in front，called a front yard，or a space in back，called a backyard.Whichever it is，owning a yard is a sign to many Americans that they are living a good life.
   So what do people do with their backyards？Some use it to start a garden.Others use it to host parties or barbecues.A common sight in an American backyard is a barbecue with hot dogs and burgers.For others，the backyard is where their dog spends most of its time.There may even be a doghouse there.
   But maybe the most common use of a backyard is as a place for children to play.
   Many backyards include a tree with a swing or a tree house.Children can play games there，such as hide and seek.For little kids，the backyard can be a paradise（天堂）.
