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.

带着新奇、幻想与迷茫，我们走进了初中，迎接我们的是为期五天的军训。我们知道，军训不仅仅是对身体的锻炼，更是对意志的考验和磨砺。
在这几天的军训里，我们学到了许多东西。记得我们在军训中做的最多的一个姿势就是站立。在烈日灸烤的操场上，我们昂首挺胸，一动不动地站立着。热气不断地从地里面往外透，脚底又酸又痛，豆大的汗珠不断地顺着我们的脸颊流下来，我们都不敢去擦，坚持站立着。有好几次我的头晕的要死，总感觉要被风吹倒似的，浑身乏力。但是我知道，这是在锻炼着我们的意志，所以每次都会在心里拼命对自己说：“坚持一会儿，再坚持一会儿就可以的了，一定要坚持住。”在站立结束后，我的心情总是很高兴的，因为我靠着自己的毅力挺到了最后。
“跑步走”是我们学的众多动作中最难、最累的。教官要求我们排面要整齐;跑步落地声音要响;眼睛要平视前方;口号要喊得响亮。要求整齐划一。一开始的时候，我们同学都觉得手脚不是自己的了，做起动作来很别扭。但经过教官的严加训练和我们自己的悟性，我们终于攻下了这个项目。
军训在辛苦训练之余，我们同学间会举行一些有趣的活动。例如拔河比赛、猜歌比赛等。在拔河比赛上，我们小组的同学虽然输了，但输赢并不重要，付出才是关键。在拔河中我们学会了团结;学会了互相鼓励加油;学会了尽全力去做一件事情。这才是拔河比赛的真谛!
时间如流水般流去，五天的军训转眼就成了回忆。回想着这次军训，一种潜藏在心中已久的感受便油然而生。的确，军训是很辛苦。但却辛苦得有收获;辛苦得有意义;辛苦得让人难忘。难忘我们军训时的\'挥汗如雨;难忘训练时教官的严肃和我们开玩笑时的样子;难忘在最后一天会操时我们的卖力表演。尽管最后会操时并没有拿到“优秀中队”的荣誉，但我们仍是胜利者，因为我们战胜了自己!
军训让我不再娇气，面对困难不再抱怨，学会了用满面笑颜来面对未来的生活。我想，这五天的军训对我来说是一次脱胎换骨的历练!
军训已是随风而去的回忆，但军训留下的共振余音仍在回响，我们要牢记军人作风，以铁的纪律来约束自己，以钢的意志来支配自己。只有懂得这样做，我们才对得起在风雨和烈日中陪伴我们的曹老师;才对得起教官的尽心尽力的训练;才对得起我们自己挥洒的汗水!

当新学期来临时，许多学生对新生活表现得很兴奋。在大学，新生快乐地享受着自由。在接下来的四年里，他们希望过着高中描绘的\'美好生活。但事实是，大学生活中有很多东西要学。
First, the major knowledge occupies the most important role. As a student, learning knowledge is their job, while many students focus on playing cellphone in the class, or just sleep. They lose interest in studying when they come to the free environment. Mastering the professional skill helps them to be competitive. The sad thing is that most of them can't realize it.
首先，专业知识占据着最重要的角色。作为一名学生，学习知识是他们的工作，而很多学生在课堂上玩手机，或者睡觉。当他们来到自由的环境后对学习失去了兴趣。掌握专业技能帮助他们提高竞争力，可悲的是，大多数人没有意识到这一点。
Second, as there is much free time, they can make use of it and gain the valuable experience. Students can join some clubs to develop more interest, or find part-time jobs. It is better than to stay in the dorm and play computer games all the time.
第二，由于空闲时间多，他们可以充分利用好这些时间，并从中获得宝贵的经验。学生可以参加一些活动来发展更多的兴趣爱好，或找份兼职工作。比呆在宿舍玩电脑游戏好多了。
A lot of students feel lost in the campus, because they don't plan campus life well. The things you learn will make you different in the future.
很多学生因为没有计划好校园生活在所以迷失了。所学到的东西会让你在未来有所作为。

3月29日，我们学校组织五年级学生去珠海实践基地军训。
第一天，我们参观了孙中山故居，回到基地玩了有趣的游戏。晚饭过后，我们举行了精彩的团辅晚会。
第二天上午，我们去体验真正的军训。一听说那里没有洗手间，也不能装水，我的心就开始往上跳——不能上厕所，又不能装水，那不明摆着军训时不能休息吗?
来到操场，只见一座楼房上嵌者八个大字：“严格要求，严格训练”。我心想：那位军官对我们的要求一定十分严格。我们将面临着一次严酷的训练。
果真如此!这位军官板着脸，说话的声音也十分洪亮。如果谁不听他的指令，就大声地批评对方，眉头就紧皱着。
无情的阳光射在我们的身上，大家一个个都汗流浃背。那时正在站军姿，我们连动都不敢动，生怕被军官处罚。这时，何展鸿动来动去，被军官发现了，于是就“光荣地”做了“大都督”。军官伸出手，指着何展鸿，怒吼道：“你，出来!”
何展鸿只好站出列。
“趴下!”军官喊。
何展鸿一脸疑惑地看着军官。
“趴下!”军官喊，“难道你不会做俯卧撑吗?!”
何展鸿只好趴下了。
我的热汗全都变作冷汗出了。
不一会儿，雨淅淅沥沥地下了起来。我心暗喜：这下应该可以休息了吧!可是军官没有丝毫反应，仍旧时不时纠正同学的姿势。我把眼斜了过去，吴文忻的脸都涨红了，手臂也在微微颤抖着。这个时候，有几个同学觉得不舒服了，就去休息了。
过了好一阵子，雨愈下愈大，有些同学甚至都哭出了声，但都被军官喝住了。
又煎熬了一阵子，军官让我们齐步走，进去遮雨处休息。大家终于松了一口气，议论纷纷。几分钟后，军官叫了声“起立!”，大家都“嗖”的一声站了起来。军官把我们带到了一处空旷地，，让我们右脚往后一点，脚尖点地，蹲了下来，膝盖不能碰地，双手放在双膝上。大约过了三十多分钟，我的双腿和双手都不停地颤抖着。好不容易可以休息了，我一躺，便躺在了地上。
最后，我们还得盘腿坐，双手放在双膝上，挺直腰。有几位同学的动作不到位，就趴着。
难熬的两个小时过去了，训练终于结束了。下午，我们回到了广州。
严格要求，严格训练。是啊，只有严格对待自己，才会成功。

历经一周的评选，我们实习生搞的军训有感征文活动在今天落下了帷幕。举行此次活动的目的是希望孩子们将军训几天的感受与成长用文字记录下来。当那些酸、甜、苦、辣，变成文字时，孩子们自然会有新的感动和顿悟。活动设立了4个奖项，15个名额。一等奖一名，二等奖三名，三等奖五名，潜力奖六名。下周一升国旗时，校长会在大会上公布获奖名单并为获奖的学生发奖状。我们实习生会抓紧时间在网页和展牌两个平台上宣传优秀文章。
读着那些孩子们的感言，我都很为他们欣慰。虽然及不上大家的文章气势滂沱或文采四溢，却一篇篇真挚感人。每一篇都是他们的真情流露。一行行质朴的文字读来仿佛见到了他们一颗颗纯真无暇的童心。他们的笑，他们的泪，他们的调皮，一切都是那么自然与真实。“路还是那条路，草还是那些草”，“而我已不再是曾经懵懂无知的孩子，我已经长大，长成了少年”。他们真的从军训中获得了许多。有的孩子到了父母、老师的艰辛;有的孩子体会到了学习机会的不易，学习时间的珍贵;有的孩子自此崇拜起了军人;有的孩子学会了坚强，学会了忍耐……孩子都很体谅老师和教官的严厉，都懂事极了。
能够遇见他们，让我觉得是世界上最美好的事情。我会把我所有拥有的知识都教给他们。在这个学期里，我要做他们的好老师。
