【正确答案】[范文] Challenge Everyone will meet with all kinds of challenges throughout one's life. What are challenges? A difficult mathematical problem may be one, a job with a deadline may be one, and your girlfriend's demands may be one. In fact anything that is difficult to achieve but you have to do is a challenge. Some of them are really difficult for you to achieve, however, some others are difficult only because you just don't like to do them. Different men treat challenges in different ways. Some just lay them aside, others just evade them, yet more others who are brave enough will directly face challenges. They take it as a pleasure to fight against a challenge and feel it an honor to achieve a victory. While the coward just takes challenges as puzzles disturbing their monotonous lives. I admire the people who dare to face challenges directly. It is they who change the world, and push the world forward. I believe that life is made up of all kinds of challenges. To achieve victories is to embody the value of humans. To challenge yourself is to prepare yourself for the challenges of the world.
