给外国作者写一般要写英语:Dear so and so, I am your fan. I like your works very much. Now I am a college student. I think your works have a great impact on me. Would you like to extract some of your works into my thesis? Thank you sincerely.
敬爱的某某,我是您的粉丝,我对您的作品十分的喜欢,我现在是一名在校的大学生,我认为您的作品对我影响很大,想把您的作品摘抄部分到我的论文里可以吗,由衷的感谢您。
注意:不用写太多,对外国人长篇大论没意义,直接一点反而可能会获得好感。
