The Great Changes in My Hometown
My hometown is a small city in the south of China. In the past few years, great changes have taken place here. Old low houses have been replaced by tall modern buildings. Narrow dirty streets are now wide and clean, with green trees and colorful flowers on both sides. There are also new shopping malls and parks for people to relax.
I think these changes come from the rapid development of our country. The government has invested a lot in building infrastructure and improving people's lives.
I feel really proud and happy about these changes. My hometown has become more beautiful and convenient. I'm looking forward to its even brighter future.Unit 1 The Changing World Section B 练习作业

My Hometown's Great Changes
My hometown is a small city in the south. In the past ten years, it has changed a lot. Old houses have been replaced by tall buildings, and new roads and parks have been built. People can now take subways to go anywhere quickly.
