Writing letters to foreign authors generally requires writing in English: Dear XXX, I am a fan of yours. I like your work very much. Now I am a college student. I think your work has a great influence on me. Would you like to extract some of your works into my paper? Thank you very much.

Note: you don't need to write too much, it doesn't make sense to foreigners, but you may feel good about it directly.
