I remember the exact moment I learned the principle of preparing for luck. I was on the wrestling team. Now, if there's one thing I can tell you about any sport, it is that wrestling is probably the sport that has the least__1__. There are only two people out on the mat, so you cannot__2__it on your teammates or your coach. And guess what? There is no__3__because we do the whole thing indoors, so you can't say, "It was raining." or "It was snowing." It makes__4__to say wrestling is the sport with the least luck. On our team were two world champions; one of them had been world champion five times. We__5__had five people who were national champions. One of them was a guy__6__the name of John. John had never been__7__in my high school wrestling competition that I could remember, __8__he was a national champion. There was nobody locally who could touch him. One day, we __9__a match with our biggest opponent( 对手 ). John went out on the mat, and about a minute and 30 seconds into the match he tried to make a particular__10__. He rolled over, and his opponent__11__him halfway through his roll. He was pinned__12__! The match was over. I remember on the bus on the way home, one of our teammates tried to__13__John by saying, "Oh, he just got lucky." And John said, "That's so stupid. The opportunity presented itself, __14__he exploited it." We used to have this big sign in our wrestling room that the coach had__15__there. "Luck is what happens when opportunity__16__preparation." John's opponent was prepared to exploit this opportunity. The probability of__17__John was not much, and he knew it. But he paid attention to the __18__opportunity to present itself, and he defeated and pinned a five time national champion. In other words, the real__19__is "Be prepared!" It's not just finding the opportunity; you have to be prepared to__20__it. 1. A. luck 2. A. accuse 3. A. stress 4. A. judgment 5. A. also 6. A. under 7. A. hurt 8. A. although 9. A. went for 10.
