My grandfather is eighty years old now. He always complains about how fast things have changed, and he often says that life used to be better.

Families aren’t families they used to be. A lot of families have broken up. If husband and wife have problems with their marriage, they no longer stay together. And mothers used to stay at home and take care of their children, but now not any more. Everyone is busy working. Mother used to spend all day cooking in the kitchen. But now the family don’t eat home-cooked food any more.

And the cars! No one walks any more. More and more people drive. Students used to walk 5 miles to school every day, even in winter. But nowadays students don’t. And in school, children don’t have to think any more.. In math class, for example, they used to add, subtract, multiply and divide(加减乘除)in their heads. Instead, they use calculators.

And people today have TV and computers, and they don’t talk to each other any more. They are too busy to talk, too busy to eat, too busy to think.

Life used to be simple, but it isn’t any more.
