My father is an engineer. He works very hard.　

　　Once I asked my father what the secret of success was. He didn”t say a word, but wrote a few words on a piece of paper and handed it to me. I looked at the paper. ()n it was written: A=　

X+Y+Z.　

　　"What does it mean?"I asked.　

　　"A means success, explained my father. "X means hard, Y means good ways, and Z means you must stop talking and start to work."　

　　That”s right. From then on, I tried my best to be better.
