Our city is becoming more and more messy and dirty. What can we do to keep our city clean and beautiful？ I have some good ideas.

To keep our city clean and beautiful，we can take bus and metro to school，because vehicle exhaust（尾氣）makes urban（城市的） air dirty. We can also walk to school. Walking is good to our health. The rubbish makes our city messy and dirty，so we can’t throw rubbish on the ground. We should put our rubbish in the bin. Trees can help keep the air clean，we should plant more trees around us.

In addition，we use plastic to make many things，but plastic can lead to soil pollution. We should use paper bags and glass bottles instead. Boys and girls，let’s try our best to keep our city cleaner and more beautiful.
