尊敬的家长们:
您们好!新年新希望,希望您们猪年大吉,心想事成!
这次由大学生自行组织举办的青少年综合素质公益培训班的完满结束,离不开各位家长的\'支持,在此向您们致以衷心的感谢!
这七天的学习,或许没能教会孩子过硬的本领,也没能看到显著的提高,但是不可否认的是这次培训班的设立,带给了他们更多的认知和浓厚的学习兴趣。当今社会,成绩优异不再是评定一个人能力强的唯一标准,只有多方面发展的人才能被人所用。这个现实的认知是我们所有家长应该知晓的。这个简单的培训只是一个起点,孩子们的漫漫之路需要你们这些伟大的导师给予更多的物质支持和精神鼓励,家长才是孩子最好的老师,所以恳请家长继续做好监督工作引导孩子自学,适当地添加学习资料书,使孩子们在课余生活中能自学到更多的文化知识。我们必须坚信着:自学也能成才!
此外,我希望这次的培训只是一个开始,这种心怀感恩乐于奉献的精神得以传承,那些能人智者也能倾出微薄之力,致力于提高沙垌镇新一代青少年的综合素质,为创建文明沙垌,和谐发展作贡献!
此致!
敬礼!
xx青年团队致上

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.
如果一封信写完了,突然又想起遗漏的事情,这时用p.s.表示,再写上遗漏的话即可,要长话短说。通常在信末签名下面几行的左方,应于正文齐头。
注意:在正式的信函中,应避免使用附言。
