Q&A
Question: I e from a poor family, and my parents do what they can to pay for my education. What I want to do is let my parents live a happy and fortable life. Where can I find riches? Do I need to leave school and find a well-paid job?
Answer: You are a considerate child.   1  An African farmer heard tales about other farmers who discovered diamond mines. These tales excited the farmer so much that he could hardly wait to sell his farm and hunt for diamonds himself.
So he sold the farm and spent the rest of his life wandering the African continent, searching unsuccessfully for the gleaming （闪烁的）stones.   2  
Meanwhile, back on the farm, the man who had bought his farm happened to be crossing a small stream on the farm one day.   3  He picked it up. It was a sparkling stone — a good size stone — and, admiring it, he later put it on his mantel（壁炉架）.
Several weeks later, a visitor looked closely at it, then he nearly became unconscious. He told the farmer it was one of the largest diamonds ever discovered. The farmer said that the stream was full of these brilliant stones, and his farmland was covered with them.   4  
If the first farmer had taken time to study and prepare himself — to learn what diamonds looked like in their rough state w and to thoroughly explore the farm he had before looking elsewhere, his wildest dreams would have e true.   5  A．I’d like to give you some advice on how to find the riches.B．Now do you have any idea of what you should do to find the riches?C．Finally, he threw himself into a river and drowned.D．However, something special he was carrying dropped into the stream.E. Needless to say, the farm turned out to be the most productive diamond mine.
F. Before I answer your questions, I want to tell you a story.
G. Suddenly he saw something gleaming at the bottom of the stream.F
