Changes in My Hometown
My hometown has changed a lot over the years. In the past, there used to be old houses. The river was very dirty. We could hardly see the blue sky. But now, there are many tall buildings in my hometown. The air is fresh, the river is clean and the water is clear. There is less pollution than before.
When I was young, the roads were narrow and the transportation conditions were bad. People went to work on foot or by bike. It took a lot of time. As time goes by, those have changed, too. The subway has been in use for many years. It is convenient for people to take the subway to go somewhere.
I am glad to see these changes. I hope my hometown will be better and better.
