     We often hear people talking about a generation gap (代沟). The name is new, but the idea

is old. Young people and their parents don't understand each other. The world has always kept

changing. During the second century after Christ a wise man said, "Bury me on my face because

in a little while everything will be turned upside down."

    There has always been a gap between generations, but more people talk about it now. Old

Mr. Ellis thinks he understands what has happened.

    "When I was a boy, I thought the world was a beautiful place. My life was very pleasant. But

when I was older, I learned about people who were treated badly, people who didn't have enough

to eat. I wanted to help them, and I married a girl who wanted to help them, too. We went to

meetings and talked a lot, but it didn't seem to make much difference. "

    "Our children grew up in a world at war. They didn't know when the fighting would stop. They

wanted their children to have nice clothes and toys. They didn't want to think about the future.

They thought nothing could be done about it."

    "Now I have grandchildren, and they have their own ideas. They are trying to make the world

better. They are trying to help other people. They're making people listen to them. I am proud

of their generation."
