不知道你现在是以什么样的心情在看这封信，是不是还想此时的我一样，正为自己渺茫的前途而感伤，还是……所以与其客套地说你好，不如发自真心的问一声：你好吗？
我先给你说说我现在的生活状态吧。
算一算我现在进入大学已经有大半年了，对学校及周围的环境也算比较熟悉了，不过我现在对大学生活似乎还不够适应，每天都有很多忙不完的事，功课的复习也总是跟不上进度。都说大学的学习是很轻松的，但是我一点也没有这种感觉，有时还很怀念那曾经深恶痛疾、朝思夜盼着想要快点结束的高三生活，毕竟那时虽然同样很忙碌，但那也是充实的。同学们忙里偷闲互相开开玩笑、打打闹闹，抑或为了同样的数学题或物理题时而埋头沉思，时而因不同的观点争论得不可开交，甚至于高三即将结束时的那场冷战……一切的一切，现在都是那么的怀念，就像那时同样怀念高中生活一样，也许人就是这样吧，不懂得珍惜眼前的生活，直至失去了才想起那时的好。所以我猜，你现在一定也很怀念四年前的我的生活吧，尽管现在的我对其抱怨不迭。
大学最重要的还是学习。这里的学习不仅仅是你在大学时期的侠义的学习知识，而是广泛的学习各种技能，提高你个人的自身素质。在大学四年里，大一时，你在学习基础课程的同时，参加各种社团活动，担任一定的职位，培养自己的处事能力和交流技巧，为将来的求职做好准备；大二时，除了完成基础课到专业课的转变，还可以广泛涉猎各个领域的知识，扩大自己的知识面，可以适当地选择与自己专业相关的兼职或感兴趣的工作，参加义工、支教等社会实践活动，进一步与社会接触；大三时，这是规划人生目标的重要阶段，在这一年，你要对自己以后的发展方向做好选择，尽量把大四的知识在大三学完，可以去请教学姐、学长的经历，选择最适合自己的人生道路；大四时，这时已是把自己送入社会的时候，可以写好自己的`求职简历，多浏览各网站，参加公司面试，如果你在大学四年有目标地坚持自己的信念与生活，那么大四就是你收获的季节。
四年之后，你或许会去读研，实现自己的学术梦想。你或许会去留学，在我梦想的国度里追溯艺术的起源；你或许会回到故乡，回到那个生你养你的小镇，闻一闻乡土的气息；你或许会愈飞愈远，漂泊到无人知晓的远方，寄一张明信片就是最淳朴的挂记。你或许找到了很好的工作，打电话跟妈妈讲时有着略显骄傲的语气。你或许还在为找到一份好工作而忧虑，却又不愿让家人担心。于是你学会了微笑，学会了把眼泪埋进心底。在我心里，这也是一种成熟，一种我还不曾拥有的勇气。曾子曰：“士不可以不弘毅，任重而道远，仁以为己任，不亦重乎？”我的大学四年，绝不是碌碌无为的四年。
四年后，我一定会成为一个具有综合能力的人，进入社会这个大家庭，用我在吉大学到的各种知识武装自己，游刃有余。
四年后，我一定能实现自己的梦想，通过吉大这个跳板，登上属于自己的舞台，尽展自己的风采。
四年后，我一定要学着自己奋斗，锻炼自己，在干出一番成绩后。
大学的四年，是一段不长不短的四年。路漫漫其修远兮，吾将上下而求索。努力吧，现在的自己，让我的大学四年，永远无悔。

how to do research
——reading after a science paper
these days i am busy preparing my dissertation which is about web usage mining . i read some english papers and learnt much from them . and now i want to say something about a paper titled “web usage mining：discovery and applications of usage patterns from web data”.
this is the first english paper i read about dissertation and gave me great help .
this paper is a review about web usage mining. it introduced web usage mining in detail . although it is a little old for it was published in its contents are very useful today . it is organized according to the sequence of web usage mining and the six main parts are introduction which tells me what is web usage mining the sources and abstraction of web data the three steps of web usage mining taxonomy and project survey websift overview privacy issues . the third and fourth parts are most important . it had a list of existing project about web usage mining which i saw many times in other papers but this paper is the one creating this list . besides it has been referred for more then twenty times . as we all know that the higher the referred number is the more important the paper is so i consider this paper to be an important and successful one in this region.
in my opinion the success of this paper dues to three reasons . the first reason is the profound computer knowledge owned by the authors . web usage mining relates to many subjects such as artificial intelligence ontology semantic analysis but the most basic knowledge is computer science . the four authors are all professors of department of computer science and engineering in university of minnesota . for myself i am not major in computer science and i am not very good at computers so i feel a little difficult to understand technologies used in this region.
second they had read a large number of papers before they wrote this paper . there are fifty nine references listed after main contents . “stand on the shoulders of giants” this sentence tell us a truth : one can never successful all by oneself . and what’s more learn from others can save a lot of time and energy especially for us new learner . how to learn from others is a skill all of us should master but learning doesn’t mean copy or plagiary . other people’s knowledge and production is just our foundation upon this foundation we must have our own thoughts and creation. there are many remarks in this paper where referred other’s production.
third the authors had the experience of developing a web usage mining project . they don’t just engage in idle theorizing so their comprehension on this issue is greatly profound. they know what we may meet in a real project development and they know how to resolve them . after reading this paper i also read some other papers written in chinese . some of them are not based on real project and can not give useful resolution . websift is the name of system they developed which can be used to data mining and analysis .
i wrote this article not only because it gave me much help in preparing my dissertation but also because it tells me how to study and how to do research . honesty and preciseness are two essential making a researcher must have . hard-working is the necessary condition leading to success . this is just the beginning of my dissertation i should learn from these four authors both their knowledge and their attitude to study.
