这也是最有效的方法之一。为了更方便大家向作者索取原文，但一定要简洁！一般都愿意向你提供。如果作者有自己的主页，可以去作者的主页看看。不过一般查找作者的主页倒不容易！记住你的信箱尽量大一点，否则一些大的文件搞不定！
Dear Mr./Mrs.: ________（Author name）
I am a graduate student of Harbin Medical University in China. I major in "________"（您的专业）. Recently, I found one of your articles, titled "__________" （Title）in Medline. I found it may help me achieve my goals in this research field. This would make a really positive contribution to my work. I would like to be able to read the full text of this article. The abstract makes the article sound very interesting. I know there is usually a fee required to obtain the full article from Medline; however, as a student, my only income is a small scholarship which is about U S $30.00 per month. I wonder if you would consider sending me the full text by Email. Perhaps you would consider this as an act of friendship between our two countries.
Thank you for your kind consideration of this request.
Sincerely: ___________（your name）
