       Thirteen-year-old Lola Walters has taken America by storm! She is nearly blind, but wowed the

crowds at the American Gymnastics Academy Long Beach Open last month.

       Lola suffers from a condition causing her to see double. She cannot see anything until she is just

five feet away. However, she competed with other young gymnasts with perfect vision. The judges

knew nothing of her condition, but they were still amazed by her perfect gymnastics skills.

       "The floor isn't any different for me," Lola says. "But the beam(平衡木) is only four inches wide,

so it's hard enough for anyone to walk on, let alone jump on. So when I start to see two beams instead

of just the one, I need to steady(稳固) myself on my feet and really focus."

       There is a saying that goes, "One minute on the stage is worth ten years off the stage." Even for

normal people, you have to work very hard to achieve success, to say nothing of a blind girl like Lola.

Can you imagine how much pain she endured(忍受) when she was practicing? It's common for her

to fall down from the beam and her accidents are more serious than other gymnasts. But that does

not stop her from practicing gymnastics.

       Now gymnastics has become Lola's passion and she plans to be a gymnastics coach when she's

older.
