Some things to keep in mind for the final draft.

1. The text should be 10 pages double spaced. The bibliography
section should be on the 11th page. 

2. A lot of people read a description of a phenomenon and paraphrased
the description in their paper, putting anything that they didn't
understand in quotations.  Bad idea.  Don't write down anything you
don't understand.

3. Use scare quotes sparingly.

4. Be careful to avoid dangling modifiers.

5. The bibliography needs to be correctly formatted. Just giving the 
name of an author/website is insufficient. Make sure you look up the
Ethnologue and consult an actual grammar. 

6. The abstract needs to be an abstract i.e. it must summarize the 
contents of the prot and give the reader a clear idea of what the
paper is about. 

7. Proofread for grammar and spelling.

And most importantly, examples, examples, examples! Your report should
have examples for all the points that you are arguing for. Follow the
textbook with respect to the presentation of examples from languages 
other than English - the original words on one line, the English glosses
on a the next line, properly aligned with the original words, followed
by the translation in the last line.
