Changes in our hometown
Over the past ten years, great changes have taken place in our hometown. In the past, the houses in our hometown were very poor,but now many people have moved into tall buildings (there are many tall buildings here and there). The water in the rivers was very dirty, but now the rivers are clean and people can swim in them. People used to walk or ride bikes, but now they can take buses or drive their own cars to go to work.
