Diligence is the key to be useful. "Are frequently compensated with good training, a hard points to", only diligent, can get good grades.

   Hua luogeng is due to the diligence, to become a famous mathematician.

   Hua luogeng in jintan county, home is very poor in childhood, dropping out of school at home, very early to help his father miscellaneous shop for a living, but he never give up the pursuit of mathematics. At eight o 'clock every night, go home after good accounts, to study their favorite mathematics, often study late into the night. In this way, day after day, year after year's efforts, hua luogeng finally got a chance to, when in tsinghua university math department assistant, he is very cherish the hard-won learning opportunities, he like a duck to water, swam in the sea of mathematics every day, give yourself only five or six hours of sleep time, it is really hard to believe. Hua luogeng even developed after lights out, also can the habit of reading. He, of course, there is no specific function, is just a kind of logical thinking activity of the mind. Under the lamp, he took a book and look at the topic to think for a moment, and turning in bed, close the meditation, start, to solve the problem in your mind run into difficulties, then turn off the bed, open the book for a while. In this way, a book can see ten days, he you can finish it 2 days, otherwise can't sleep. Hua luogeng who is considered the unusual assistant. After studying so hard to learn, later, became a famous mathematician.

   We learn from hua luogeng, in the later study, should be hard work, hard work, so as to achieve good results.

   勤奋是成为有用之才的钥匙。“勤能补拙是良训，一分辛苦一分才”，只有勤奋上进，才能取得好成绩。

   华罗庚正是由于这种勤奋，才成为著名的数学家。

   华罗庚出生于江苏金坛县，小时候家里很清贫，很早就辍学在家，帮父亲打理杂铺为生，但他从没有放弃对数学的追求。每天晚上八点，回家算好帐目后，才能钻研自己喜欢的数学，常常学习到深夜。就这样，日复一日，年复一年的努力，华罗庚终于得到机会，在清华大学当数学系助理员，他非常珍惜来之不易的学习机会，他如鱼得水，每天都游弋在数学的海洋里，只给自己留下五、六个小时睡眠时间，说起来真是让人难以相信。华罗庚甚至养成了熄灯之后，也能看书的习惯。他当然没有什么特异功能，只是头脑中的一种逻辑思维活动。他在灯下拿来一本书，看着题目思考一会儿，然后熄灯躺在床上，闭目静思，开始在头脑中做题，碰到难处，再翻身下床，打开书看一会儿。就这样，一本能看十天的书，他二天就能看完，要不然睡不着觉。华罗庚被人们看成不寻常的助理员。也就是经过这样勤奋学习再学习，后来，成为了著名的数学家。

   我们要向华罗庚学习，在以后的学习中，应该刻苦，勤奋努力，这样才能取得优异成绩。
