My grandfather is an eighty-year-old man. He always complains about how fast things have changed, and he often says that life used to be better. Families aren't families the way they used to be. A lot of families have broken down. If husband and wife have problems with their marriage, they no longer stay together. And mother used to stay at home and take care of their children, but now everyone is working. No one has time to look after children at home. And the cars! No one walks any more: everyone drives. We used to walk five miles to school every day, even in winter. But now they don't. And in school the children don't have to think any more. In maths class, for example, we used to add, subtract, multiply and divide in our heads. Kids don't use their heads any more, instead, they use calculators( 计算器 ). Most families have computers now, but in the past we didn't have computers. We didn't even have lights. My mother used to spend all day cooking in the kitchen. But now nobody eats at home and cooks food any more. And people don't talk to each other any more. They are too busy to talk, too busy to eat, too busy to think.... Life used 1o be simple, but it isn't any more.
