出国度假利弊英文作文【一】
我是复旦大学数学系教授，在此写信推荐王XX。我认识王XX自大学二年级，担任他的导师。在我眼中，他是一个勤奋的学生和一个令人钦佩的孩子。
他是一个令人印象深刻的学生，因为在他大一年级的时候他不得不克服与挑战严重疾病。在我的数学课上第一次遇见他，并没有觉得他有什么特别的!然而，他的成绩好得高过我对他的期望。王XX试图把所有困难的早期数学课程，同时包括离散数学、高等数学，线性代数都学好，在此期间我是不知道他是有病在身的。而大多数学生认为王XX同学就算只准备一门课程的考试都很难，然而，最终他取得一个令所有人都意外的期末成绩，使我深深意识到他那不寻常的决心，他给我们展示了当面对艰难时是如何的坚强。王同学和我经常谈到的各种数学和计算机科学的概念和问题。
在这些讨论，我总能发现他的见解很独特，是个聪明的孩子。他不仅很快理解概念，同时给他提出的问题，他能够分析并提出解决方案。最重要的是，王同学发现任何问题他都认真负责重新审查，如发现不确定性问题，他立即清除他们。我认为这种想法是成为一名优秀的计算机程序员必须具备的基本条件。作为他的导师我会利用机会时常观察进行思想工作。王老师的论文“网络神经”提出很具有挑战性的议题。在我们的书籍中对于这一议题及其应用是非常罕见的。在中国很少有人研究过这个话题，因此该材料选择是有限的。王同学不仅迎接这项挑战，同时在实践中超越其职责分析出了来源和测试精度。
他的学习能力与工作能力非常让我自豪。王同学是很聪明和勤奋的学生。我知道，如果有机会出国留学，他梦想着在美国成为伟大的程序员。他会抓住一切机会实现这一梦想，同时有智慧和能力实现这一梦想。希望你能接受王XX同学的申请并给予他机会!
出国度假利弊英文作文【二】
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.
出国度假利弊英文作文【三】
海边的游客可真多啊，他们三三两两，有的在游泳，有的在冲浪，有的在晒太阳，个个兴高采烈。
小猪一家撑起了太阳伞，刚刚坐定，笨笨就拿起一根香蕉，剥掉皮，三口两口就吃掉了，随手把香蕉皮扔在了沙滩上。接着他又打开可乐罐，一口气喝完，把空罐子扔进了大海里。看着空罐子在海面上飘来飘去，笨笨觉得很好玩，又接着扔，不一会儿，空罐子都沉了下去。小猪笨笨就这样吃了扔，扔了吃，海滩成了垃圾场。
傍晚，游客们散了，海边平静了下来，一阵海潮涨过，沙滩上的垃圾都被卷进了大海。海底的小贝壳非常生气，这么多的垃圾把她的家给弄赃了，“有什么办法能把这些垃圾清理掉呢？”小贝壳很着急。
第二天，阳光升起的时候，蓝天象往常一样来看望大海，她发现大海不象以前那么明亮了，就关切地问：“大海，以前，你是那么干净、美丽。白云和小鸟最喜欢拿你当镜子，怎么一下子就变了样？”
大海叹了口气说：“唉！放暑假了，家家户户都 我眼中的暑假是快乐的、是欢愉的、是漫长的、是丰富的、是有趣的……我们在考试前，总是盼望着过暑假，想着到了暑假就没有老师的指责、没有大堆的作业，没有……，如果暑假是天空，我就是小鸟，在蔚蓝的.天空幽幽回旋，时而直插云霄，时而又和云朵嬉戏；如果暑假是大海，我就是鱼儿，飞快的穿梭在珊瑚群中，又兴奋的冲出水面……
我是个小书虫，平时只忙于学习，没有更多空闲时间来看书，到了暑假，我就可以抽出许多时间来看书，我又可以吃上精神食粮了，我就可以抽出许多时间来去图书馆看书，更可以把自己喜欢的书籍借回家，在书籍的海洋畅游了。
我还很爱游泳，游泳是最能锻炼身体的运动，平常要上课，还要写作业，占用了我们运动时间，到了暑假，可好了，我又可以在水中自由自在的游泳了。因此，我每天都去游泳，游泳即可以锻炼身体，又可以避暑。
正因为有了暑假，让我有了充足的时间，去图书馆学习自己感兴趣的自然、科学知识，和朋友一起去游泳，抛开了那似乎永远也听不完的课，写不完的作业，我们有了时间，就可以做一些有意义、开心的事情，暑假真好！喜欢带孩子到我这里游玩，把各种垃圾都扔进了我家。”说着，大海摇了摇头。
又过了几天，小兔丽丽一家也来大海边度假。她看见海边有许多垃圾，就找来了小狗贝贝、小猫花花、小马皮皮和他们的家人，开始清理垃圾。小猪笨笨听说以后也赶来了，大海高兴得拍起阵阵浪花，连声说：“谢谢你们！谢谢你们！”
一天下来，大家终于把垃圾清理完了。看着大家劳累了一天，小贝壳感动地说：“谢谢你们把我们的家园打扫干净了，我要把最美丽的珍珠献给你们。”小伙伴们连忙摆手，异口同声地说：“保护环境是我们应该做的。”小猪笨笨也高兴地说：“今天是我暑假中最开心、最有意义的一天。”
