    Here is a story：A man sees a butterfly（蝴蝶）．The butterfly tries to get out of its chrysalis（蛹）．

Feeling sorry for it，the man decides to help．He cuts the chrysalis and the butterfly comes out easily．Surprisingly enough，the butterfly is unable to fly．If the butterfly doesn't struggle（挣扎；奋斗） to leave

the chrysalis，it can't fly!The struggle develops the energy in the butterfly which makes it fly．Similarly，the challenges of life bring out the best in young people and make the fly．

    When people are young，meeting and overcoming challenges will make them strong and ready to face

life．When we look at successful people，we see that the most successful of them are people who have

had to struggle．One famous businessman，who now owns many big supermarkets，used to carry clothes on his back and sell them from door to door when he was young．Another successful man is Dennis．His father died when he was only twenty．His father's death forced him to maturefast．He had to bring

up a family of nine people．He took up the challenges and overcame them．Today his brothers and sisters are leading successful lives．

    Sometimes challenges do not appear to us because we keep away from them．So some parents and teachers actively encourage young people to face challenges．They might organize some activities for young people which provide them with challenges，like rock﹣climbing，camping，volunteer work and so on．However，just passing exams will not prepare a person for life．We must meet and overcome challenges．The young people of today will become the leaders of tomorrow．For countries to continue to become successful，it is important that the young people learn to meet challenges and overcome them．
