Science, as we think, was born when the Greek(希腊) philosopher ( 哲学家 ) Thales ( about 640-546 B.C.) asked a difficult question: What makes up our universe?

No one had a ready answer, so Thales went on studying the earth around him, the sky and the stars. He saw so much water on earth and so much water falling from the sky as rain that he decided water must be the basic substance ( 物质 ) of the universe.

Other Greek thinkers became interested in this question. They suggested other answers. One said that because air lies around the earth, it must be air that makes up all things. Another said that fire, appearing in different forms, was the building block of the universe.

The Greek philosophers were feeling their way towards the ideas on which chemistry is based. Centuries later, scientists proved that the universe is made up of certain basic substances. But the list is much more complicated than the Greeks realized. We now know of 103 basic substances which we call “ elements ( 元素 )”.

Jack Evans quarreled with his neighbour,Ellen Brown. Mrs. Brown had a dog. Jack did not like dogs. He wanted Mrs. Brown to give away or sell her dog,but she refused.

“I'll take you to court if you don't,” he said.

Mrs. Brown laughed at him. She was not worried.

Jack thought,“I must talk to a lawyer, but lawyers are expensive. I don't want to waste my money. I will waste it if I don't win my case against Mrs. Brown and her dog.”?

Then Jack had an idea. There was a young lawyer in the town. He did not have much work. Not many people knew about him. “I'll visit him,” Jack thought. “He needs work.” He visited the young lawyer in his office. “I need some advice,” he said.

“Good. I want to take my neighbour to court. However, I will pay for your advice only if you think I will win the case in court.”?

“All right,” he said. “I agree. I will listen to your problem. I will give you honest advice. You will pay me only if I think you can win in court.”?

Jack told him about the problem. The lawyer listened carefully. Sometimes he made notes. When Jack finished, the lawyer sat back in his chair and said, “You will win your case. I have no doubt about it. May I take your case to court?”

Jack stood up and walked towards the door. “No, thank you,” he said. “I will not take it to court.”?

“What about my fee?” the lawyer asked. “You have to keep your promise.”
