Three men traveling on a train began a conversition about the world's greatest wonders.
“ In my opinion,” the first man said, “ the Egyptian pyramids are the world’s greatest wonder. Although they were built thousands of years ago, they are still standing. And remember: the people who built them had only simple tools. They didn’t have the kind of machinery that builders and engineers have today.
“ I agree that the Egyptian pyramids are wonderful,” the second man said, “ But I don’t think they’re the greatest wonder. I believe computers are more wonderful than the pyramids. They have taken people to the moon and brought them back safely. They carry out mathematical calculations in seconds that would take a person a hundred years to do.”
He turned to the third man and asked, “ What do you think is the greatest wonder in the world?”
The third man thought for a long time, then he said, “ Well, I agree that the pyramids are wonderful, and I agree that computers are wonderful, too. However, in my opinion, the most wonderful thing in the world is the thermos(保温瓶).”
And he took a thermos out of his bag and held it up.
The other two men were very surprised. “ A thermos?” they exclaimed(大声说), “ But that’s a simple thing.”
“ Oh, no, it’s not,” the third man said, “ in the winter you put in a hot drink and it stays hot, in the summer you put in a cold drink and it stays cold. How does the thermos know whether it is winter or summer?”

“ Can I have a carrot, Mom?” Bruce asked.
“I don’t have any carrots,” his mom said. “How about an apple?”
“No,” said Bruce. “It has to be a carrot.”
“Why do you want a carrot?” asked his mom
“You always say carrots help your eyes.” said Bruce. “If I eat one now, it might help me see in the dark.”
Would eating a carrot really help Bruce? What is special about carrots? What makes a carrot special is its color. Carrots are orange because they contain(包含) bta-carotene( 胡萝卜素). Beta-carotene is a way of saying vitamin A. Your eyes need vitamin A. It helps them work.

Every time your eye changes light into messages, a little bit of the chemical is used up. By the end of the day, you’ve looked at hundreds of things. That uses up a lot of the chemical. Your eyes need to make more.
What should you eat if you don’t like carrots? Don’t worry. Other fruits and vegetables have vitamin A, too. The secret is in their color.
