Keep our city clean
Our city is messy and dirty now. We can do some things to keep our city clean.
First, smoke from cars makes the air dirty. We can take the metro and the bus to school. We can walk to school too.
Second, black smoke from factories makes the air dirty. We can plant more trees. They can help keep the air clean. We can move some factories away from our city too.
Third, the river is dirty. There are some rubbish in the river. We should throw rubbish in the bin.
I hope our city will be better and better. Let’s keep our city clean.
