The Changing World
How are these two photos different
The big photo shows a beautiful green place with a river running through green fields. There are many trees and plants too. The old black-and-white photo shows the same area with almost no trees or grass.
2. Why do you think this place changed so much
I think this place changed so much because people took good care of it. They planted many trees and protected the river. With their hard work, the environment became better and better.
3. How has your hometown changed over time
My hometown has changed a lot. Ten years ago, there were few tall buildings and the roads were narrow. Now, many new buildings have been built and the roads are much wider. The environment is cleaner and there are more parks.
