        The environment in my city is becoming worse. Factories burn things 
to make energy. People cut down many trees. It is bad for the air, too. There 
are many cars on the streets. It also pollutes the air. People throw away 
rubbish everywhere. This pollutes the land.
        As far as we know, it is our common dream to build a green home. 
What can people in my city do to protect the environment?
        First, we should plant trees to make the air clean. Second, we must 
stop throwing away so much rubbish. Last but not least, we should go to 
work by bus or by bike. All in all, we must try to protect our environment 
and make the world more beautiful.
