狗是我的老师。它们按照自然规律生活，一生只穿一件衣裳，对主人忠诚，不用担心吃什么，睡在哪里，没有象人那样多的欲望和烦恼。它们天生有看家的本领，所以讨人喜欢。

   Dogs are my teachers. They live according to natural rules. They never change their clothes all life. They’re also loyal to their lords and needn’t worry about what to eat or
where to sleep. Besides, They don’t have as many desires or griefs as men do.
Men are fond of them for they are gifted in watching out.
