    It was the homecoming parade in Rockwall,Texas,and cheerleader Tyra Winters,was riding on the top of one of the school's floats(彩车）。As it slowly made its way down the wide road,the 17-year-old enthusiastically waved at the crowd,all the while soaking in the music,laughter,and applause.

All of a sudden.a horrific scream sounded.Looking down,Winters saw a two-year-old on the sidewalk gasping for air.his extremely worried mother begging for help.The boy,Clarke Hornback Lad been sucking on a piece of candy when it slid down the back of his mouth,lodging in his throat and blocking his windpipe.

＂I see a little bright red face and his mom's begging,Someone help me,someone help me.'"

Winters told KTVT."There was no coughing;there was no breathing,Clarke's mother,Nicole Homback,later told news station NBCDFW.He was just gasping for air."No one seemed to know how to help.

Except for Winters.A senior with dreams of becoming a pediatric surgeon,she had learned the Heimlich maneuver and CPR.Knowing that the clock was ticking,she leaped off the moving float and ran to the child.

By the time she got to Clarke,his face had turned purple."I got him!"she yelled to Nicole as she grabbed the boy from her."I tilted him and gave a good three back thrusts,"she told the local CBS station.

Soon,the boy coughed up the piece of candy,gasped,and began breathing again.Without another word,Winters handed Clarke back to his mother and ran back to her float before it could leave her behind.

It all happened so fast,Nicole never had time to thank the teen.Winters' s heroic actions left Nicole speechless."I don't really have any words,"she says."The words that you would say to anyone who does something for you is' thank you.' But that doesn't seem good enough."
