文档介绍：Twenty-One Suggestions for Writing Good Scientific Papers: Notes on Writing Papers and Theses
1.  Know your audience and write for that specific audience.
Scientific and technical writing can almost never be 'general purpose'; it must be written for a specific audience. For the kinds of writing addressed here, that audience will generally be munity of ecologists who read a particular journal or study a particular subject. munity is represented by your professor for class papers. In all cases, you must adopt the style and level of writing that is appropriate for your audience. Stylistic conventions and acceptable jargon can vary tremendously from one field to another, and to some extent, from one journal to another. If you are unfamiliar with the conventions of a field, study them as they are manifested in a selection of highly regarded papers and in the "Instructions for Authors" for key journals.
2.  Your supervisor/professor is not here to teach you basic grammar and spelling.
The more time and emotional energy she or he spends on correcting basic English usage, the less remains for issues of content or fine-tuning. You are responsible for mastering the basics of the language; save your supervisor's time for more substantive issues. A few glitches and non-parallel tenses will sip through your own careful editing, but there is no excuse for frequent ungrammatical sentences
