Subject: Telephone
Dear Sir,
I would like to remind you that we are in want of a telephone for each dormitory. As a university student, we need to cope with the daily increasing communications with teachers, friends and people outside the campus.
We need a telephone to get and send message, which is important for us. Though most of us have mobile phones and e-mail address, a telephone in the dormitory is after all the most convenient and cheapest tool of communication. I hope that you will pay attention to this problem and solve it as soon as possible.
Regards. Yours,Li Ming

通常国际刊物要求所要刊登的文章字数,包括摘要部分不超过1万字。而对文章摘要部分的字数要求则更少。因此写摘要时,应用最为简练的语言来表达论文之精华。论文摘要的重点应放在所研究的成果和结论上。
国际会议要求的论文摘要的字数不等,一般为200字-500字。而国际刊物要求所刊登的论文摘要的字数通常是100字-200字。摘要的位置一般放在一篇文章的最前面,内容上涵盖全文,并直接点明全旨。语言上要求尽量简炼。摘要通常多采用第三人称撰写。
