DENVER，COORADO——What does it take to be a hero? In the case of five Denver children，it only takes a cry for help．Here’s the story of these five heroes as Gary Lewis， the man they helped，tells it．
“I like to work on my old car．It’s my hobby．I wanted to put a new transmission(传动装置)in the car．I put the car up on blocks(大块木头)because I wanted to get under it．I was trying to get the old transmission out when suddenly the car moved forward and fell off the blocks．It came down on my chest．I couldn’t breathe．
“I tried to shout for help for about five minutes，but I almost could not breathe．Could anyone hear me? Was I going to die? Then all of a sudden I heard some little children from the neighbourhood．They were running to the car and saying，‘What happened，sir?’
“Get help，please．I can’t breathe，I told them．One of the children ran to his house and to1d his mom to call 911．Then, before I knew what was happening，all of the children were around the car. They used every muscle(肌肉)in their bodies to lift(抬起)the car，and I was able to get out from under it．”
Lewis got out from under the car with just a few cuts．He didn’t even have to go to the hospital．“These children are my heroes．”he says．“I don’t know how they did it．but I am lucky to be alive．”
Raymond Brown，father of two of the children，is very proud of them．“We try to teach them to do the right thing．This shows we’re doing it the right way，I guess，”he says．
