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.
每当看到那部剃须刀,七彩的童年生活犹如放电影般呈现在了我的脑海中,久久挥之不去。
那年我才四岁,有一天我去姥爷家,看着家中柜上面各种各样的摆设品,强烈的好奇心驱使我不住地摸摸这儿,玩玩那儿。忽然老爷手中的一个黑盒子”吸引了我的注意力,他长得并不好看。却能发出嗡嗡的声音。姥爷拿着它在嘴边蹭来蹭去,一副悠闲自得的样子,那感觉简直像腾云驾雾的活神仙。而站在一旁的我早就看得心痒痒了,眼睛直直地盯着黑盒子,恨不得马上就体验一下那感觉。好不容易等到姥爷出去,我立刻一个箭步冲上去。拿起黑盒子”,随手按了一个按钮,那玩意儿立刻不停的震动起来,犹如蜜蜂采蜜般嗡嗡地叫起来,真好听。我尝试着慢慢用它在脸上蹭来蹭去,啊!那感觉仿佛把整个脸都埋进了棉花里,皮肤都跟着不停颤动,舒服极了。这时姥爷回来了,他神情怪异地盯着我看,忽然缓缓地问:你的眉毛哪儿去了?”我闻声大惊,急忙拿起镜子一瞧,嘿,果真我的眉毛竟不翼而飞啦!我吓得哇哇大哭起来,姥爷却忍不住哈哈大笑。这时我又瞅见了镜中那个狼狈不堪的我,又不禁破涕而笑。
冰心曾说过,童年是梦中的真,是真中的梦,是回忆时含泪的微笑,这句话是多么贴切啊。
童年,是五颜六色的。今晚,我们走进小菜叔叔的童年,听他的趣事。
小菜叔叔露出洁白的牙齿,笑眯眯地说起一岁时的故事。他讲的时而快时而慢,还一边做着风趣幽默的动作,有时把手举得老高,有时掐住自己的脸,有时走来走去像回忆什么,搞得大家哭笑不得。
在他讲述完趣事,还让我猜故事名。有的.同学不假思索地举起手,小菜叔叔却在黑板上写了3个字—30法则(思考30秒后再举手),大家只好把手放下来,个个绞尽脑汁认真思考起来。30秒一到,同学们争先恐后地举起手来抢答,“瀑布”、“反击”、“改诗”……,答案许许多多,可小菜叔叔都说是错的,回去再好好想想。
因为时间的关系,所以从一岁,直接连跳到七岁了。这次他想听听同学们七岁的趣事,大概是有些同学胆怯,或者一时想不起什么趣事,所以举手的人很少。见此情景,他说:“想要学习好,就要当小老师。”这话一出,空中立刻出现了密密麻麻的小手。同学们各自讲说了童年发生的趣事,终于轮到小菜叔叔讲了,好奇的我一直在想:什么事情是他七岁时最深刻的呢?是不是和我一样?结果他记忆犹新的是面试,他讲的绘声绘色加上夸张的动作,让所有的同学听得都入了迷。
调皮的时间总是喜欢出来捣蛋,一转眼,就结束了,好想和大家一一分享太多的童年,因为它总是将不完!
