I was coaching girls’track in Iowa and there was a young discus (铁饼) thrower on the
team with__1__potential (潜力)．Here goes her story.
At the end of our training__2__the district track meet，this discus thrower，Lucy，
asked me if she__3__come to the school on Sunday for a little__4__training.
I agreed.The year before，she had placed second at the district meet and__5__missed
going to the state meet.She had won every discus ，__6__that district meet！And，
her throws in the competitions had__7__been between 106′1〞and 110′10〞.Something
began to__8__me.Why couldn’t Lucy__9__to get the discus to 111 feet？I wondered if it
was more a psychological barrier (心理障碍)__10__a physical one.I decided to try
something__11__.I made up my mind to__12__to Lucy.
On Sunday，after her drills，I said，“Why don’t you throw five or six good ones for
me to__13__？”She began to throw again，but__14__were farther than what she had
already thrown.But，I didn’t tell Lucy.As I was measuring the__15__one，I pulled out
some more tape (卷尺) and yelled out to her，“Come to see this！This one is__16__！”
It wasn’t.Lucy，thinking that this was a personal best，jumped wildly into the air in__17__.
The next afternoon，at the district meet，Lucy__18__with a personal best throw of
114′10〞！Just 24 hours after I had lied to her.However，this time she had__19__thrown
the discus four feet further than she had ever thrown it before.
Sometimes we__20__our own barriers in our mind.So learn to take control of your mind.
