老师说：时间就是金钱。于是得: time=money (1); 老师又说：知识就是力量。于是得: knowledge=power (2); 一个人在一定时间内做的功越多，功率越大， 于是可将功率表示为： power=work/time. （3）； 将（1）和（2）式代入（3），得: knowledge=work/money, 将其变形为 money=work/knowledge .

你们看奇迹出现了，当 knowledge 趋向于0 时，我们的 money 无穷大；反之，knowledge越大，付出同样努力地结果是money越少。

结论：我们读那么多书做甚?

Dear friends,I once read a saying which goes as follows "No dream is ever too big and No dreamer is ever too small" which motivates us to achieve our dreams.Although they may be tough and afflictive,yet since we realize our dreams, take this heavy burden on our shoulders and pay for them,we will pick up these amazing stars step by step......My dream's owning a roadstep,and yours?
