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.
文章线索明朗,主题突出,紧紧围绕思念爸爸进行。文章边叙事边抒情。结尾处集中表达情感,既照应开头又总结全文。首尾连贯,一气呵成。
美中不足的是:文章结尾处的永远一次用的不恰当。
文章语言虽朴实却令人感动,字里行间可以看出小作者对爸爸的想念。
我非常有幸能够来到世界著名的医学学府—卡洛琳斯卡大学进修学习。一到这里,即被这里浓郁、严谨、平等的学术气氛所吸引、所感染。在这里,没有学术权威和小辈之分,在科学面前人人平等,都有发表自己见解和观点的权利与空间;有时为了一个小小的问题,学生会与大教授争论不休,毫无畏惧权威之意。我所在的科室每周二都有组会,这是一个大家相互学习交流的好机会。每周由一个研究者主讲自己最近的科研进展,然后,就是最热烈的时刻,大家毫无保留各抒己见、畅所欲言,对当天的主讲者提出各种各样的.问题和建议。我通过这样的学术交流,也收获颇多,不仅提高了自己的英文能力,而且也常常能捕捉到被我忽略的、而却非常有用的信息,使我在研究中茅塞顿开,更好地促进了下一步的研究工作。在这里,研究人员一般都比较敬业,比如我们实验室有位老太太实验员因为要进行动物实验,每天早上很早就到单位开始工作,如果实验没有结束,她也不会因干满八小时而下班,从她这里改变了我原来对欧洲人的印象,即比较懒散。
在瑞典工作学习的日子,接触了不少博士生,了解了瑞典培养研究生的制度。在瑞典对博士生的要求很高,除了修满40-80学分外,博士论文还必须包含至少4篇在国际期刊和主要国际会议上发表的文章;此外,博士生还必须承担20%的助教任务。博士生的文章被SCI等等录用,导师一般会资助他们参加几次国际会议。我想这是一个非常好的激励机制,更有利于培养高质量的研究生,也值得我们国内借鉴。
