Modern Mandarin Chinese Grammar: A Practical Guide, by Claudia Ross and Jing-hen Sheng Ma, Routledge, 2006. It's a large 400-page paperback, June 2006. I have enough grammars, but this one caught my eye because although the first part is the usual set of rules, the second larger part is about situational use... how do you express comparisons? refer to future events? how to refer to obligations and expectations? The latter section is organized by social need and topic.
This reminds me of the Nihongo Notes series, but less anecdotal, more organized. This book describes an area of communication, and how various means of expressing this vary. Recommended.
