     For a long time, a boy wondered why his next-desk classmate was always the first in the class,

while he could only rank (排名) the 21st. At home, he asked his mom, " Am I more stupid than other

kids? How come I always fall behind?I can't come up with an answer. " Mom knew that her son's

self-respect (自尊心) had been hurt by the ranking system, but she didn't know what to say to help.

    She had really wanted to say that intelligence (智力) differs and that yes, her son's friend was really

a smarter boy. But that would make her son lose heart. So she didn't say it.

    Her son and his friend went on to a high school that year. Although her son tried as hard as he could,

his friend still left him behind. But she was proud of her boy for his hard work. It was around this time

she decided to take him on a trip to the seaside. On the trip, she at last found an answer for him.

Today her son no longer cares about rankings. He doesn't have to, for he himself is now at the top of the

class in a university. When invited to his old high school, he mentioned a valuable childhood experience:

Once on a trip to the sea, my mother and I were lying on the beach. She pointed to the sea and said to

me: Do you see seabirds fighting for food out there?When a wave (海浪) comes near, the little birds

rise quickly. The "clumsy"  seagulls (海鸥) are far less quick and have to tried hard to get away from the

wave. But they prove to have the biggest, strongest wings,which open the widest and allow the bird to

travel the furthest. When the season changes, they leave for foreign shores, leaving the little birds behind.

Son, I have feeling that you are one of those seagulls. "
