Department of the SPECIAL CLASS GIFTED for YOUTHS

Dear Sir or Madam:
I take great pleasure in recommending Wang Yong, one of my favorite students, for admission into your distinguished graduate program.
Mr. Wang was admitted in 1986 at 14 years of age into the SPECIAL CLASS for the GIFTED YOUTHS, my university's unique program that caters to the intellectual needs of unusually talented Chinese youngsters. It was a rare privilege he earned with his nearly impeccable academic performance through the years of his elementary and secondary school.
He impressed me almost as he entered into my university, a major cradle of china's scientific and technological talents. At the time, members of the Gifted Class all had to spend half a month studying by themselves the principles of calculus and then take an exam so that we could evaluate their self-study capability. Mr. Wang scored the highest grade in that exam. He also exhibited a keenly whetted mind during class discussions. To my regret at the time, his English was not as good as his mathematics or physics.(缺点介绍，公正真实 But I noticed he made a point of working especially hard in improving his English during his five undergraduate years with us. By now, he seems to be at least as proficient in English as most of his former classmates in the Gifted Class.
In my experience with Mr. Wang, I was impressed with not only his extraordinary intelligence but also his ambitions and persistence. I am sure that Mr. Wang will be an outstanding student in any doctoral program that he may care to enroll in. So I would like to support him firmly in his quest recommendation into account when considering his application. I would greatly appreciate it you decide to accept him as he wishes.
Yours sincerely
****
Professor and Deputy Head

假如有一款智慧芯片，那么这个世界是会变得有趣还是无聊，那就请我们来想象一下吧！
智慧芯片：每个人只要有了智慧芯片，所有的知识就印在他的脑子里了，他就不用学习了，而且身体不会感冒、生病。智慧芯片永远不会影响到人的身体的`每一位器官和结构，它的功能有：增加智力，增加知识，增加身体的抵抗能力，在极端的情况下出谋划策。在脑子里安装上智慧芯片只有好处没有坏处。还有保护地球的功能，节约用任何资源。
1岁儿童，还没学会穿裤子和穿鞋子，就脱口背出：《关雎》关关雎鸠，在河之洲。窈窕淑女，君子好逑。参差荇菜，左右流之。窈窕淑女，寤寐求之……2岁儿童，不用上幼儿园，就脱口背出：《出师表》先帝创业未半而中道崩殂，今天下三分，益州疲弊，此诚危急存亡之秋也。然侍卫之臣不懈于内，忠志之士……这样，每个人就天资聪慧，不用再为学习而担忧了。
如果这个世界上每个人都有智慧芯片，那么这个世界会是一个多么无聊的世界。
一位博士在街上散步，顺嘴背了一首古诗：国破山河在看，城春草木深。接着一位清洁工脱口而出：感时花溅泪，恨别鸟惊心。这样，如果每个人都有不可计算的知识，也有不可攀爬的本事，那么这个世界还有什么意思？都说知识是无限的，可是如果有了智慧芯片，还剩下什么知识呢？
不过有了智慧芯片，这个世界上有很多东西都会消失，不存在了。身体不会感冒、生病，这样就没有医院了；不用学习、不用，这样就没有老师和学校了；不生病也就不用吃药，就没有药店了。还剩些什么呢？
这样这个世界也就不会有那么多的空气污染，也不会河水海水不干净了。
而这个世界上只有一个人没有安装智慧芯片，他觉得，只要他活得自在，活得快乐，有没有知识是不重要的。而这个世界唯有他自己独自清醒，他不同其他人爱慕虚荣，所以他也不会安装智慧芯片。世界上总会有那么一个人的。

In capacity as Professor of Mathematics at Fudan University?I'm writing to recommend Mr. Wang?Gesintosyour PhD program in Computer Science. I have known Mr. Wang since his sophomore year of college?and have acted as his thesis advisormentor. In my experience?he is a gifteddiligent student?and an admirably hard worker.
Wang is an impressive student because he has been forced to overcome the significant challenge of a serious illness during his freshman year. When I first met Wang in my Discrete Math class?he did not appear to be anything special to me. While his exam scores were good?they were not as high as I would now expect of him.
What I didn't know then was that due to his illness?Wang was attempting to take all of the difficult early mathematics courses at one time?including Discrete Mathematics?Advanced Mathematics?Linear Algebra?and Possibilities. While most students found preparing for just one set of these exams difficult?Wang was overwhelmed by four of them. But in the end?he achieved an impressive score on the final exam?which made me conscious of his unusual determination he demonstrates when confronting difficult challenges.
Mr. WangI have often talked about a variety of mathematicscomputer science conceptsproblems. During these discussions?I always found him to be delightfully intelligent. Not only does he quickly understand the conceptsproblems presented to him?he is able to analyze these problemspresent solutions. But perhaps most important is that Wang's thinking is intensely rigorous. When looking at any question?he carefully scrutinizes itif he finds any uncertain issue
he clears them up immediately. I believe this kind of thought is essential to become an excellent computer programmer.
Serving as his thesis advisor?I had a first-hand opportunity to observe the way in which Wang's mind works. In his senor thesis?Mr. Wang mainly discussed two challenging questions in regards to″ANN″。 In our books in China?knowledge of ANNits uses are very rare. Few people in China have studied this topicconsequently?the materials that are available on ANN are limited. Working on this difficult project?not only did Mr. Wang rise to the challenge?but he went abovebeyond the call of duty to analyze his secondary sourcestest them for accuracy in practice. In this way?he found mistakes in the book that we use. His diligencehard work made me extremely proud of him.

Dear all,
I am writing this letter to express my gratitude to my parents for teaching me to be positive and to be strong. “Educating the mind without educating the heart is no education at all.” is the opinion held by Aristotle. It is the experience of our forefathers, however, it is correct even today, including my parenting.
It is widely acknowledged that parenting, which can also be explained as family education, is of great significance in our character forming and manner acquiring. To be more detailed, setting good examples instead of just giving precepts is the greatest achievement of my parents. They not only taught me to think for the best and prepare for the worst; they taught me how. They not only told me the benefits of being strong in mind; they proved it. All those things require huge amount of time and work, but it’s worth it.
Without my parents’ contribution and education, I would never be who I am now. But most importantly, I would never be more gratitude to them than today.
Yours,
XXX

春天， 万物复苏，小河水哗哗地顺流而下； 活泼机灵的小鸟们在枝头喳喳地纵情歌唱； 小草们神不知鬼不觉地从地下探出了脑袋，大地换上了绿色的新衣； 小野花们争先恐后地展示着自己的美丽； 一棵棵大树好像正在返老还童， 抽出嫩黄色的新芽；。年迈的`凤凰木也紧跟着春天的步伐， 吐出米粒大小的嫩叶， 就像刚出生的婴儿那般娇嫩。
夏天，太阳像一个火炉似地炙烤着地面。凤凰木的叶子早已变成了深绿色，枝条也向四周扩展了许多，变成了一把绿色的大伞。当太阳透过茂密的树叶筛下一束束金光时， 美丽的凤凰花绽开了一张张笑脸，好像给凤凰木披上了红色的霞衣。
秋天，凤凰树的叶子慢慢地变成了金黄色，在微风吹拂下纷纷飘落下来， 给地面铺上了一层厚厚的金色地毯。课间十分钟，我和小伙伴们在凤凰树下尽情地玩耍、嬉闹，甭提有多高兴了。
冬天，刺骨的寒风从耳边呼呼地刮过，古老的凤凰木褪去了繁华，仿佛一个弯着腰、知识渊博的老学者，正在讲述着她一百多年来的沧桑岁月， 并勉励我们克服各种困难、勤奋学习，成为对国家有贡献的人才。
这就是我们百年老校的百年古树---凤凰木。
