If we have no knowledge, we cannot succeed in doing any work. Why? Because knowledge is power. With knowledge we have conquered nature and invented steamers, trains and airplanes. We can send messages by telegram. We can talk with our friends by telephone.As is well known, we students are the future masters of the nation. She needs us very much. If we do not make efforts to acquire knowledge, how can we render service to her ?假如大家沒常識，大家就不可以做成功什么事情。為何？由于常識就是力量。馮藉常識大家征服了大自然，并且創造了輪船，火車與飛機。大家可以用電報傳遞消息。大家可以用電話和朋友談話。如大家都知道，大家學生都是國家將來的主人翁。她很需要大家。假如大家不努力去獲得常識，以后怎么樣來報效她呢？
