life is struggle
      everything in the world is in constant struggle, 'struggle' in the sense of competition in natural selection among organisms.
     animals and plants struggle for their existence.  nature provides them with weapons for that struggle.  lions have claws; fish have scales; roses have thorns. they use their weapons for the un-
avoidable war of existence. nature also orders us to struggle;when we obey nature, we win our existence.
      the result of struggle is the evolution of a better society.in order to surpass others, one has to devote himself to what he does. if every individual does so. the society will make progress.
      struggle is inevitable.  but we should struggle with sportsmanship, not stand in the way of others in order to achieve our own success. it is only by struggling in such a way that mankind will see a world getting more glorious day by day.

生存就是竞争
    世上万物都置身于不断的竞争中，“竞争”就是生物体之间在自然选择过程中竞赛的意思。
    动物和植物为生存而竞争，大自然赋予了它们进行竞争的武器。狮子有爪，鱼有鳞，玫瑰有刺。它们使用这些武器为不可避免的生存之战而战。大自然也迫使我们去竞争；如果我们遵循自然规律，我们就能生存。
    竞争的结果是社会向好的方向发展。一个人为了超过其他人，应该致力于自己的工作。如果每个人都做到这点，社会就会进步。
    竞争是不可避免的。但是我们应该以运动员所具有的道德去参与竞争，而不能为了自己的成功去挡住别人的路。
    只有通过这种方式的竞争，人类才能拥有一个日益辉煌的世界。
