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.
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.
《我的青春在延安》,是一部由孙骁骁(潇湘)、郑恺(赵劲飞)主演的红色青春偶像剧,它以中共在延安筹备“七大”为切入点,讲述了那个时代的年轻人 对于祖国的热爱与奉献的故事。在剧中,潇湘和赵劲飞是一对恋人,他们为了信仰来到了延安,用他们自己的青春故事,重现了那段激情燃烧的岁月。
有一次,他们在执行任务的途中遇到了一些困难,赵劲飞急中生智,飞快地把枪架在日本首领的脖子上,并让潇湘等人快跑,潇湘担心极了,好几次都想冲进 去。过了半晌,赵劲飞终于回来了,潇湘颤抖着用枪指着赵劲飞,告诉他不要再逞英雄了,这样很危险,与其死在敌人的`手里,不如死在她的手里。赵劲飞深情地表 白:“我一直告诉自己要活着回来,因为我舍不得你。”是啊,赵劲飞虽然随时可能牺牲,但是他一定会坚守他们的海誓山盟的,他爱她,不管是以前,现在,以 后······只要为了她,他什么都可以做。
在潇湘误会赵劲飞,想要跟他分手的时候,他说:“我不敢给你任何承诺,因为我不知道哪次执行任务将会发生什么,如果你要离开我,我同意。”他多么善 良呀,他从来不为自己着想,爱的人幸福,那就好·····大结局的时候,赵劲飞带一个连去迎接七大的最后一批代表,结果日本间谍王彪盗取了信息,用电台发 出信息:“让赵劲飞连夜行动。”赵劲飞觉得很奇怪,但还是照做了,结果就中了日军的埋伏,在走投无路的情况下,勇敢机智的他和另外七个人组成了敢死队吸引 火力,让日军以为支援部队到了,其他的人掩护代表离开。慢慢的八个人只剩了他一个,他的腿也被打断了,身上负了多处重伤。他慢慢地爬上了一棵老树边。这 时,日军的大部队通通过来了,潇湘的支援部队也过来了。潇湘看见已经不能动的赵劲飞,终于一次性释放出自己的情感,眼泪扑通地滴下来,大声地喊着:“赵劲 飞,我爱你!”一片寂静,赵劲飞听到后欣慰地笑了,笑得那么灿烂,那么阳光,他深爱着的潇湘他的萧湘,终于理解了他心又和他贴在了一起。这时候,《你我的 表达》翩翩响起来,天空是蒙蒙的灰,在怀念谁,升华透明的泪,用来回味·····本来感人的情节配上这令人心碎的音乐,我想在此刻连木头人都会动之以情 吧,我趴在桌子上不顾一切地嚎啕大哭起来,赵劲飞不是一直盼望着和潇湘幸福生活的那一天吗?这一天总会到的,我相信不会的,他为了潇湘会坚持下去的,我相 信结局不可能那么残忍,不是说有情人终成眷属吗?这个电视剧一定会有续集,那就是赵劲飞被抢救了,他和潇湘一起幸福地生活着,没有人能拆散他们,他们的爱 情终将海枯石烂,白头偕老!
最后,***说:“也许后人在提起七大的时候,有些革命战士可能连名字都没有留下,但是我们要记住他们,不能忘记他们。”是啊,赵劲飞只是典型战士中普通的一员,就是他们用自己的鲜血和青春换来了祖国的安宁,默默无闻,不求回报。

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。
