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.

信头是指发信人的姓名(单位名称、地址和日期，一般写在信纸的右上角。一般公函或商业信函的信纸上都印有单位或公司的名称、地址、电话号码等，因此就只需在信头下面的右边写上写信日期就可以了。
英文地址的写法与中文完全不同，地址的名称按从小到大的顺序：第一行写门牌号码和街名;第二行写县、市、省、州、邮编、国名;然后再写日期。标点符号一般在每一行的末尾都不用，但在每一行的之间，该用的还要用，例如在写日期的时候。
其中日期的写法，如1997年7月30日，英文为：july 30，1997(最为普遍;july 30th，1997;30th july，1997等。1997不可写成97。

??氛围带来好成绩高二记叙文900字各位老师，同学们：大家晚上好!
我是来自高二七班的黄小维，今天我演讲的题目是好氛围带来好成绩。
氛围，是指一种感染力、影响力和控制力的环境因素。如果营造一个好的学习氛围，就会产生人心思学的巨大吸引力、不学下行的高压力和好学有为的驱动力。
《学记》认为：“独学而无友，则孤陋而寡闻。”这说明，学习过程中环境对学习的结果有很大的影响。在科学技术迅猛发展的今天，学校环境条件正变得日趋复杂多样，手机、游戏机、MP4等电子产品都在或多或少的影响着我们的学习，学习氛围对学习过程的影响也更加重要突出。
古有孟母三迁的典故，孟子的母亲为防止孟子沾染恶习，不惜三次举家搬迁，最终落户学宫之院。而孟子也正是由于被学院里传来的琅琅读书声所吸引，继而对学习产生浓厚的兴趣并从此发奋读书，终成大儒。由此可见，一个良好的学习氛围对于我们学业上的发展的确起着不容忽视的作用。
如果你在一个守纪律的\'班集体中，你也会成为一位守纪的学生；如果你在一个爱好读书的班集体中，你也会成为一位爱读书的学生；如果你的班级中的同学都勤奋学习，你也将成为一个勤奋好学的学生。不难发现，凡是拥有着良好氛围的班级体，它所培养出的都会是优秀的学生。这也正是因为良好的学习氛围是同学之间产生了竞争意识。竞争的压力转变为了同学们拼搏的动力，从而使大家都努力学习。事实上，他们在被别人影响时也影响了别人。
可见，一个良好的班集体对于每一个学生思想形态的形成，对于良好学习习惯与行为习惯的养成有着巨大的教育作用。
我认为，我们班这次成绩的进步便是因为有良好的学习氛围。同学们在平时你追我赶，互相学习，共同进步。在学习委员吴深等一批同学的带领下学习氛围愈加浓厚。班级的整体进步，同学们都有不小的收获，懂得了“一分耕耘，一分收获”，明白了只要用心、认真的学，就一定会有进步。
同学们，作为学生，我们首先应该培养自己的责任感，既要对自己负责也要对他人负责。我们既要用踏实认真地态度对待学习，一步一个脚印，努力掌握所学知识；同时，又要互相帮助、互相监督，在班级里学会尊重，学会合作，养成良好的学习习惯，形成严谨求实的学风。
谢谢大家
