位置在下面称呼语隔一行，是信的核心部分。因此要求正文层次分明、简单易懂。和中文信不同的\'是，正文中一般不用hello!(你好!
正文有缩进式和齐头式两种。每段书信第一行的第一个字母稍微向右缩进些，通常以五个字母为宜，每段第二行从左面顶格写起，这就是缩进式。
但美国人写信各段落往往不用缩进式，用齐头式，即每一行都从左面顶格写起。商务信件大都采用齐头式的写法。

埋头工作的您可否想到，多少次深夜回家，孩子已然睡去？多少次清晨出门，孩子还在睡梦中？多少次答应陪孩子玩，却一而再再而三地食言？殊不知，您的“失陪”错过了多少孩子成长过程中的精彩瞬间。请重视与孩子在一起的时光，作为爸爸，再忙也要每天回家吃晚饭，每天和孩子玩一次游戏；作为妈妈，再累也要每天给孩子拥抱，每天给孩子讲一个故事。

过得可好。上次你说你现在很焦虑因为你觉得很难学好英语。别担心。我觉得要提高英语你得一步步来。我会帮你的。在我看来，首先应该要培养你对英语的兴趣。根据我的经验，我认为看英文电影，听美妙的英文歌曲以及在互联网上与他人用英语交流会有很大的帮助。其次，你要预习，这样可以让你理解老师在课堂上说的东西。我知道你觉得上英语课很无聊，但你必须强迫自己聚精会神的听。一段时间后，你会感觉到学习英语变得容易些了。剩下的步骤下一次我会告诉你的。顺便提一下，自从一年前你们家搬到湖南后我们就没见过面。你有没有想过暑假的时候回来看看我，我们可以一起学习英语。期待你的回复。
Best wishes,
Li

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.
