You asked about the changes in my hometown. Let me tell you something about them. In the past, the roads were rough and narrow, making it hard for people to go out. But now, new highways have been built, which connect our town to the nearest city. This makes travel much more convenient than before. We used to live in small, simple houses, but now we have moved into spacious flats with modern facilities. The hills around our town were bare ten years ago, but now they are covered with green trees and flowers. Our school has also changed—we now have a new library and multimedia classrooms for better learning. I’m proud of these changes and I love my hometown more than ever.
