总之,留学学习是一全过程,不光是在课堂上学校里学习,还要在当地的社会和生活中的学习。以后在试验室在试习期甚至打工中都是重要的学习。以上是我在匆忙中谈的几点,不一定全面,希望你自己去领会、把握和实践。另外,我们现在的生意也比较忙,一旦闲暇,我和***妈都很想念你,借用鲁迅的一句诗:无情未必真豪杰,怜子如何不丈夫?我们就你一个儿子,年过半百,却相隔千山万水,父子之情,想必你也能理解一些。希望你有时间就打电话回来,使我们更了解你的情况。***妈给你寄来的东西收到没有?你还需要什么就打电话回来。还有,出家门时要关好水电气闸门,在玩耍的地方离开时要回头看一下,别掉东西了。希努力学习,保重身体。

阿文说,他每次回国前,手机就响个不停,亲戚朋友总央求他带这带那,这些东西或是价格较国内便宜,或是国内没得卖,或只因是“外国货”。
小鱼:在国外,你帮朋友带得最多的东西是什么?
阿文:各种都有。帮热衷甜食的朋友带过巧克力;朋友里好多热爱运动的,会让我带一些很有名的球队的球鞋、球衣,有时甚至会带袜子;还带过电脑,因为一些国外牌子的`电脑在国内卖得比较贵,在国外买则会便宜一些。
小鱼:如果不是受人所托,你自己倾向给家人朋友带什么礼物?
阿文:其实,现在大部分产品国内都可以买得到,这对我选择礼物也是个很大的困扰,回国之前一般都要出去逛好几次,看到我觉得新鲜的东西就赶紧买下。我跟你讲一个我买过的最有意思的东西,因为我有一个女性朋友非常喜欢野营,但是每次在郊外上厕所就会感觉特别不方便,我就给她买了个野外上厕所的收集袋,里面有石灰粉,用完可以当垃圾带走,既不会有味道,也不会污染环境。
小鱼:我听过,好多演员在野外拍戏时也会用到。
阿文:对。其实这一类稀奇古怪的东西,日本是最多的,我的同学还买过新鲜空气吸收器,把器材一端套在植物上,一端套在嘴上,像呼吸器一样。其实买这些东西主要是为了好玩。
小鱼:有没有带什么东西会被拦下来的?
阿文:我倒没有这样的经历,不过我还真在机场碰过一次,有个亚洲旅客回国带了一些肉制品,被检查出来,因为这种生鲜类的规定都比较严格。
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.
