    The world is changing very fast. In the past，my grandparents lived in a small house. It was very old. They didn't have enough food or clothes. There was a small tree beside the house. There weren't any televisions or telephones. Now they live in a big and beautiful house. They've got lots of food and clothes. They watch TV every day. They can use the computer，too.
