 Girls Playing on Boys' Sports Teams 

     In the US today, more than 100,000 girls play sports once considered to be “boys only”. Girl players have chances to play almost any sport they want thanks to laws that require leagues to welcome girls. Some of these girls have become leaders on boy’s teams.
     In some cases, however, girls playing on boy’s teams have caused argument especially in contact sports, such as baseball, football and wrestling(摔跤). Cassy Herkelman, 15, wrestles for her high school team in Cedar Falls, Iowa. Lean, quick and strong, Cassy has won dozens of matches against boys. But in 2011,at the Iowa State Wrestling Championships, one of her rivals, Joel Northrup, refused to wrestle her. "Wrestling is a contact sport", he said later. "I do not believe that it is suitable for a boy to compete against a girl in this manner”.
     Joel's decision to give up the match was unusual. Most boys who play with girls say they quickly forget that they are competing with or against a girl. Though girls tend to be smaller and less strong than boys, there is no evidence that they are more likely to suffer injury.
     Still, some people insist that girls should stay on their own teams. They say allowing girls to take part in boys' sports could hurt girls' teams by drawing away some of the top players. Besides, it isn't fair to boys, who must risk the shame of losing to a girl.
     In fact, many experts believe that there should be more chances for boys and girls to compete together and against each other. In school and at work later in life they must learn to work together and to respect each other's different skills and strengths.
