不相信自己的意志，永远也做不成将军。

春秋战国时代，一位父亲和他的儿子出征打战。父亲已做了将军，儿子还只是马前卒。又一阵号角吹响，战鼓雷鸣了，父亲庄严地托起一个箭囊，其中插着一只箭。父亲郑重对儿子说：“这是家袭宝箭，配带身边，力量无穷，但千万不可抽出来。”

那是一个极其精美的箭囊，厚牛皮打制，镶着幽幽泛光的铜边儿，再看露出的箭尾。一眼便能认定用上等的孔雀羽毛制作。儿子喜上眉梢，贪婪地推想箭杆、箭头的模样，耳旁仿佛嗖嗖地箭声掠过，敌方的主帅应声折马而毙. 果然，配带宝箭的儿子英勇非凡，所向披靡。当鸣金收兵的号角吹响时，儿子再也禁不住得胜的豪气，完全背弃了父亲的叮嘱，强烈的欲望驱赶着他呼一声就拔出宝箭，试图看个究竟。骤然间他惊呆了。

一只断箭，箭囊里装着一只折断的箭。

我一直刳着只断箭打仗呢！儿子吓出了一身冷汗，仿佛顷刻间失去支柱的房子，轰然意志坍塌了。

结果不言自明，儿子惨死于乱军之中。

拂开蒙蒙的硝烟，父亲拣起那柄断箭，沉重地啐一口道：“不相信自己的意志，永远也做不成将军。”

把胜败寄托在一只宝箭上，多么愚蠢，而当一个人把生命的核心与把柄交给别人，又多么危险！比如把希望寄托在儿女身上；把幸福寄托在丈夫身上；把生活保障寄托在单位身上??

温馨提示：自己才是一只箭，若要它坚韧，若要它锋利，若要它百步穿杨，百发百中，磨砺它，拯救它的都只能是自己。

630年，来自欧洲的殖民者在美洲经历了一场恐慌：在如今美国田纳西地区东部，人们发现大量的蝉仿佛一夜之间从地底冒出，每公顷数百万只蝉、一棵树下约4万个孔，这实在让人害怕。几个星期过后，蝉儿销声匿迹。不过，令人诧异的是，17年之后，这段历史又重新上演了一次；而再过了17年，“没有

改写的剧本”重被搬出；直到XX年，正好是23次。由此得出一项结论，那里的蝉生命周期就是17年。

这一现象引起了科学家的注意，多年来大量的实际观测数据表明，蝉的生命周期大都为质数。比如，科学家发现，在北美洲北部地区其周期为17年，而在北美洲南部地区都是13年，亚洲的蝉周期为5年、3年。为什么是17、13、5、3等质数，而不是偶数呢？

进化论给了这个问题一个比较合理的答案。

生物学家们认为，蝉最初可能具有各种不同的生命周期，如1、2、3、4、5、6、13、17年等。但对于不同生命周期的蝉而言，其遭遇天敌的几率是不同的。如果蝉的生命周期是偶数，如12年，那么它每次登陆地面的时候，都会不幸碰见那些生命周期为1年、2年、3年、4年、6年以及12年的天敌，使得种群生存受威胁，这些生命周期为偶数的蝉就会因为在生存竞争中处于劣势而被淘汰掉。

与此相反的是，生命周期是质数的蝉，则幸运多了，因为它们可以大大降低在地面与天敌遭遇的几率，从而一代一代顽强地生存下来。在漫长的进化过程中，剩下大量这些3、5、13、17年等质数周期的蝉就恰恰是“物竞天择，适者生存”的极好证明。

对此理论，在XX年，德国马普学会分子生理学研究所以及智利大学的科学家们通过实验，给予了合理的证明。他们建立了一个“猎人-猎物”的数学模型———即将蝉比作“猎物”，其天敌比作“猎人”———用数论证明了蝉选择质数作为生命周期可以稳定地保存种群数量。

蝉的生命质数现象，说到底是一种躲避天敌的策略，是进化过程中自然选择导致的结果，是一种极为普通的生物现象。在漫长的流年岁月中，一代一代的蝉儿在“知了知了”的叫声中逝去，它们不知道，神秘的大自然在为它们精确计算着各自的“天命”。这种“天命”运用到社会生活中，就是禅的哲学。 经商也好、科研也好、学习也好，必须注重“新、奇、特”。千人齐挤独木桥，必定会有大片落水者；万人竞上羊肠道，必定会有许多掉崖者。只有“新、奇、特”，才会像那些生命周期是质数的蝉一样，在可能的情况下尽量减少“天敌”，才有可能更好地生存。

Everytime I am asked what I want to do in the future. I think a minute and say being a doctor is my dream job.

Doctor is an other kind of artist who does human art by fighting with diseases and making people feel good. I think it is a pleasure to try my best to bring happiness to others. It is a feeling of pride and I am fond of it. In modern life, a mass of people work day and night to seek wealth and as a result they ignore their health. It is known that strong body is a foundation of beatific life. I dreamed to be an excellent doctor who can help them have a right to enjoy life again. Curing people is a doctor's holy responsibility.

Being a doctor is my dream job, now I should study hard to gain more knowledge to reach my goal.

Everyone is attracted by beauty and beauty is powerful. But what is true beauty? Perhaps you can get the answer from the following story.

This morning I went to the market to buy some vegetables with my parents. On the way we all highly praised a young man in western-style clothes and leather shoes who was riding by. But he rode so fast that he knocked an old lady down carelessly.Instead of stopping, he pretended not to see this and rode away quickly. We were all very angry with the young man. To our happiness, a girl in plain dress ran forward at once, helped the lady up and took her home. We all praised the girl.

From this we know we cannot judge a person by his appearance. A person who is dressed beautifully may not have a beautiful soul. Only a person who has a beautiful soul is really beautiful.

Youth is not a time of life, it is a state of mind ; it is not rosy cheeks , red lips and supple knees, it is a matter of the emotions : it is the freshness ; it is the freshness of the deep springs of life .

Youth means a temperamental predominance of courage over timidity of the appetite , for adventure over the love of ease. This often exists in a man of 60 more than a boy of 20 . Nobody grows old merely by a number of years . We

grow old by deserting our ideals.

Years wrinkle the skin , but to give up enthusiasm wrinkles the soul . Worry ,
