出国留学的利弊 英语作文【一】
上世纪八十年代，手机开始使用，但只有有钱人家才有手机，到了九十年代，手机开始普及但却很笨重，随着时代的快速发展，人们的通讯工具日益增加，手机变得小巧了，功能也增加了很多，不管男女老少几乎人手一台，成为了我们日常必不可少的物品。然而手机却有利有弊。
在我们的日常生活中，首先，手机可以让我们随时随地和家人联系，这不仅在我们外出时可以使父母放心，也可以在我们遇到危险时及时求助；其次，手机可以便于朋友交流，能够增进友谊，在我们学习遇到困难时，还可以与同学讨论；再次，手机小巧方便携带，我们可以看到有价值的拍下来并及时与朋友进行分享；然后，手机中还有闹钟功能，我们不必再使用笨重的闹钟，不管在哪里手机里的闹钟都可以提醒我们，这个时间给做什么事情了。最后，我们还可在手机上浏览信息，及时知道面面俱到的最新消息。
手机固然便利，然而也有弊端。
首先，健康是大家共同关心的问题手机对人类的健康有着一定的影响。睡觉时，很多人把手机放枕边，手机的辐射会对人类的中枢神经系统造成机能性障碍，引起头痛、头昏、失眠、多梦和脱发等症状，有的人面部还会有刺激感。很多人经常熄灯后玩手机，手机的强光，会是黄斑部病变，轻者眼睛干涩，重者失明。其次，现在很多人得了“手机依赖症”，这严重耽误学习和工作。再次，现在学生们都有手机，档次各不相同，这极容易造成心里不平衡，引起攀比之风，给父母造成经济负担。最后，手机是贵重物品，这不仅给不法分子带来了偷窃的机会，还有可能引起一些不良学生偷盗的现象。严重影响了校园治安。
手机有利有弊，但只要我们合理的使用手机，扬长避短，发挥它应有的多用，造福我们的学习、工作、生活。我们应管理好自己的生活，作为一名中学生，我们应从我做起，对于合理使用，并用它传播正能量。
出国留学的利弊 英语作文【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.
