" grandchildren strategics " in have account " the bosom friend tells the other, 100 battle do not danger " . During war of American north and south, lincoln treats the enemy's manner, what showed this one famous remark intuitionisticly is actual apply. Probably more modern version is: Be close to your friend, but want more composition the enemy that is close to you. If want to defeat the enemy, besides the actual strength that increases oneself, also need to understand the weak point of the other side at the same time. Serve as a student now we, although should not encounter the enemy with killing need, there still can be of all kinds competitor in the life.
《孙子兵法》里有记载“知己知彼，百战不殆”。美国南北战争期间，林肯对待敌人的态度，直观地表现出了这一名言的实际运用。一个或许更加现代的说法是：亲近你的朋友，但要更亲近你的敌人。如果想要打败敌人，除了提高自身的实力，同时也需要了解对方的弱点。现在作为学生的我们，虽然应该不会遇到需要杀害的敌人，可生活中依然存在着各类的竞争对手。
Will tell from some kind of meaning, now socially before competitive comparing more intense. A lot of parents hope his child can be taken an examination of attend famous brand college, can find smooth and steady job, life quality can rise somewhat. But good university also accepts so much student every year only, not be everybody can be entered. Since somebody can take so called good job, that does so called poor work with respect to meeting somebody; Life quality was measured harder, the level of everybody is different. Below this kind of circumstance, people succeeds in what think for themselves and try hard.
从某种意义上来讲，现在社会上的竞争比以前的更加激烈。许多家长们都希望自己的孩子能考上名牌大学，能找到安稳的工作，生活质量能有所提高。但好的大学每年也就只收那么多学生，不是所有人都能进。既然有人能拿到所谓的好工作，那就会有人做所谓的差工作；生活质量就更难衡量了，每个人的标准都不一样。在这种情况下，人们都在为他们自己认为的成功而努力。
Major student tries hard in the future that is his, I am same also. Went up after high school, I also realized the difference with others gradually. Be in the school, we are protected too well by the teacher, the one's job that abides by a student can be praised, do not defend custom to also won't be criticized, this let us produce a kind " the thing should be such " illusive, think other school also is mixed we are same. And since the school after organizing a student to enter the race of different course for many times, I experienced my inadequacy deeply from inside these matches. Since then, I take out time to see the contest of a few each course inscribe as far as possible, also meet at the same time a few more advertent students are commonly used (maths) website. Because I realize, I am the following the competitor is not merely with the classmate of school, it is the classmate of whole world each district more, understand their plan, I also can know I and their difference, go shortening hard this difference, strive for can surmount them one day.
大部分学生都在为自己的未来而努力，我也一样。上了高中后，我也渐渐意识到了和别人的差距。在学校，我们被老师保护得太好了，遵守学生的本职就会被表扬，不守规矩也不会被批评，这让我们产生了一种“事情就该是这样”的错觉，以为其它学校也和我们一样。而自从学校多次组织学生参加不同科目的竞赛后，我从这些比赛中深刻地体会到了自己的不足。从那以后，我尽量抽出时间去看一些各科目的竞赛题，同时也会留意一些学生们常用的（数学）网站。因为我意识到，我以后的竞争对手不只是同校的同学，更是全世界各地的同学，了解到他们的进度，我也就能知道我和他们的差距，努力去缩短这个差距，争取有一天可以超越他们。
If want to beat rival truly, be about to understand him. Know this individual the more, can find his fatal weak point more, shoot dead a life next.
如果真正想要打败对手，就要去了解他。越是了解这个人，就越能找到他致命的弱点，然后一击毙命。
