前几天是我校一年一度的校运会。很开心终于迎来了这个难得的校运会。今年的校运会对我的意义非常的不一般,今年我参加了这一次校运会。
校运会刚开始的时候我感到十分紧张,我一直但心我发挥不好,没有为班级争光;没有取得好成绩。因为这些但心,以至于我昨晚没有休息好。在差不多到我的时候,我竟感到有点头晕。我一开始想要放弃,但当我看到她以后,我的这种想法就不在有了。她叫上官玖,我们平时叫她玖儿。她的体育非常好,但她在小学的时候脚受过伤,只要天气不好她的脚就会疼。
校运会那天,天气非常不好。就快到她了,她的脚突然疼起来了。但她说:体育在乎的是那种永远不放弃的精神,跟输赢没关系。这从她怎么说过之后,退出比赛的事情就被我抛出九霄云外去了。我和她站在跑到上,我心里清楚,开弓没有回头箭,我必须得坚持下去,坚持就是胜利。
同学们为我们加油的欢呼声让我更加紧张了。玖儿说:“没关系的,重在参与。”听了她这句话让我的紧张感瞬间没有了。开始了,我时不时的看她一眼,我看到了她一脸的痛苦。我心中有一个念想,我一定要有前三。玖儿的梦想我来帮你实现。
我用全身的力量冲冲进了前三。玖儿轻轻的跟我说:“恭喜你,喜得前三。”我对她笑着说:“你也不错。”我拿了奖杯,送给玖儿,微笑着对她说:“玖儿,祝你生日快乐。你的体育精神很值得我们学习。”她以微笑像我表达感谢。我们的友谊是无坚不摧的。
前几日是我院一年一度的校运会。很开心总算迈入了这一难能可贵的校运会。2020年的校运会一件事的实际意义十分的不一般,2020年我报名参加了这一次校运会。
校运会一开始的情况下我觉得十分焦虑不安,我一直但心我充分发挥不太好,沒有为班集体增光添彩;沒有获得优异成绩。由于这种但心,以致于我昨天晚上沒有歇息好。在类似到我的情况下,我竟觉得有点头晕。我一开始要想舍弃,但当我们见到她之后,我的这类念头就没有拥有。她叫上宫玖,大家平常叫她玖儿。她的体育文化很好,但她在中小学的情况下脚受了伤,要是气温不太好她的脚就会疼。
校运会那一天,气温十分不太好。就快到她了,她的脚忽然疼起来了。但他说:体育文化在意的是那类始终永不放弃的精神实质,跟胜负没关系。这从她怎么讲过以后,撤出赛事的事儿就一不小心抛出去九霄云外来到。我俩立在跑到上,我内心清晰,开弓沒有回过头箭,我务必得坚持到底,坚持不懈便是获胜。
学生们为大家给油的欢笑声要我更为焦虑不安了。玖儿说:“没关系的,重在参与。”听了她这话要我的紧张一瞬间没了。开始了,我隔三差五的看她一眼,我看到了她一脸的痛楚。我心中有一个执念,我一定要有前三。玖儿的理想我来帮你完成。
我用全身上下的能量充充进了前三。玖儿轻轻地的告诉我:“祝贺你了,喜得前三。”我对她笑着说:“你也非常好。”我拿了奖牌,赠给玖儿,笑容着对他说:“玖儿,祝你们祝你生日快乐。你的拼搏精神很非常值得大家学习培训。”她以笑容像我表达感谢。大家的友情是所向披靡的。

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.
