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.

在孩子们每个人的学习和生活中，都会有第一次的尝试与体验，它不断地激励和启发我们，让我们不断地获得成长。
这是我的第一次亲自下厨的故事。
那是在一个傍晚，我从外面游玩回到家后，发现桌上有一张便条，上面写着：儿子，爸妈晚上有重要的饭局，你爷爷奶奶又出去看表演，今晚你就自己照顾一下你自己吧！读完后，心想：看来今晚得自己做饭给自己吃了。
我连忙带上钱去菜场，转了一圈后就买了点西红柿和鸡蛋回来。于是，我拿出了西红柿，快步走进了厨房。
首先，我拿出两只鸡蛋，相互间“啪”的一声，只见那蛋黄和蛋清随即“哧哧”的流入锅中，我先让鸡蛋在平底锅上煎，但却发现怎么都没法煎，又是忙活了一阵子，这才知道原来是煤气开关忘了开了，于是赶忙把开关拧开。
这时我把煤气的开关拧开，等锅里的鸡蛋熟了，我用锅铲有模有样地将煎蛋“噌噌噌”地取出，此时此刻我的内心很紧张，生怕将煎蛋给弄糊了。
接着，我又拿出了西红柿，把它放在洗菜盆里用开水烫了下，我又将西红柿的皮剥了，小心翼翼地将切盘取出，然后又拿出刀，慢慢地切着西红柿，下了一番功夫后总算是切好了。只不过切得是“参差不齐，大小各异”啊！准备再做一道美味可口的糖拌西红柿。
菜总算是做好了，接着我又把中午的米饭放在微波炉中热了一下，随着微波炉“啪”的一声，米饭热好了。这一顿由我独自下厨且“不一样”的晚餐就大功告成了。我很兴奋的、迫不急待的尝了尝自己的“劳动成果”，心里还是美滋滋的！
在我们的生活中，我们会遇到很多的第一次尝试，只要我们认真尝试地做了，那我们所收获到的正是面对诸多新生事物的勇气和想把事情做好的决心。

a tale of two cities occupies a central place in the canon of charles dickens\'s works. this novel of the french revolution was originally serialized in the author\'s own periodical all the year round. weekly publication of chapters 1-3 of book 1 began on april 30, 1859. in an innovative move, dickens simultaneously released installments of the novel on a monthly basis, beginning with all of book 1 in june and concluding with the last eight chapters of book 3 in december. dickens took advantage of the novel\'s serial publication to experiment with characterization, plot, and theme. he described the work in a letter to his friend john forster, cited in rudi glancy\'s a tale of two cities: dickens\'s revolutionary novel, as \"a picturesque story rising in every chapter, with characters true to nature, but whom the story should express more than they should express themselves by dialogue.\" the novel that emerged from his experimentation is now regarded as one of dickens\'s most popular and most innovative works.
dickens\'s work was very popular with the reading public when it was first published. one review in the magazine athenaeum stated that a tale of two cities had attracted the praise of a hundred thousand readers. on the other hand, a whole set of critics, most notably sir james fitzjames stephen writing in saturday review, criticized the novel precisely for its popularity. \"most of the critics writing in the intellectual and literary journals of the day considered popular success a good reason to condemn a work,\" explains glancy. \"if the public liked it, they certainly could not be seen to approve of it at all.\" modern critical opinion, however, has given the novel an important place among dickens\'s most mature works of fiction.

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。

“山回路转不见君，雪上空留马行处。”课本上岑参诗句里的别离唯美而凄凉。一首写别离的小诗，把我的思绪牵往封尘的记忆……
我能记住的最早的别离，是四岁刚上幼儿园的时候。尽管很模糊，但依稀记得自己抱着妈妈的腿大哭。连续好几天，都是在老师的耐心抚慰下逐渐平静。直到某天，我突然明白我的哭喊都是无用功，我总要步入陌生的环境，而且别离不代表失去。我接受了和母亲短暂的`别离。这一课，我学会了独立。
到了小学毕业，我要和熟悉的同学们别离。第一次毕业的味道是苦涩的。同学们眼含泪光，手牵着手，哽咽地唱着：“长亭外，古道边，芳草碧连天”等离别之歌。大家回忆过往同老师、同学们的种种，围成一圈讲述着小学六年的难忘回忆和奇闻趣事，别离的苦涩味道中，泛出一抹回甘。我们都感慨时光流逝飞快，还没来得及慢慢品味就已成往昔。我们懊悔惋惜着那些被我们得过且过、狼吞虎咽地浪费的时光。这一课，我学会了珍惜当下。
初中第三年，在大家都忙着备战中考时，我离开了熟悉的城市。和小学不同，这回是我和所有同学的别离。我心中难免暗自神伤。同学们纷纷递来卡片和信纸，过来安慰我，以后常联系。大家都为我加油，祝福我考上理想高中……回到家，翻看着同学们的留言，到了最后一张，是我最好的朋友写的：“海内存知己，天涯若比邻。”我的心一下变得明亮起来，抬起头，有了看向更辽阔的远方的勇气。这一课，我学会了豁达。
别离似雨，浇洒在人生的每一个角落，每一滴雨水都在打磨着我心灵的雨伞，每一滴雨水都是一位小老师，教导我学会坚强、独立和珍惜……
别离，是人生的必修课。
