　　　Our city of Tianjin has a big changed in these years.In the old Tianjin people usually live in low and small house. Old Tianjin only have narrow and dirty streets. Roads often traffic jams.People only have fewer parks.
　　But in these years we can find the environment is no longer a dirty, mixed and disorderly, but all around us full of green.And in old city, people are only on foot or rid bicycle. Now almost families have there own cars.And we live in high and large flats. Streets are wide and clean.In the new Tianjin bus,subways and trains is common.More and more parks are feer.The city is changing now,I hope our city is more and more perfect.
