英语作文辩证逻辑实例：On Perseverance

　　On Perseverance

　　Try and try until you succeed． This saying shows the importance of perseverance． I have found through experience that only through hard work can we succeed．Many people have failed in their work or studies， precisely because they had no perseverance． Life， in general， as in many things we do， has never been easy． No one promised us what it would be．

　　So， if we want to succeed in life， we must be brave to win． This is the standard that differentiates people who succeed in life and those who don＇t．

　　论毅力

　　努力，努力，再努力直至成功，这句俗语说明了毅力的重要性。我通过经验发现只有经过艰苦的努力，才能获得成功。许多人在工作或学习中失败了，恰好是因为他们缺乏毅力。总之，生活就和我们做的许多事情一样，从来就不是容易的。没有人给我们许诺未来生活是什么样子。

　　因此，如果我们要想获得生活的成功，我们就必须勇于拼搏。这是区别获得生活成功的人和不成功的人的标准。
