Each of the eight units in Grammar Choices contains: an overview of the grammar topic; a preview test that allows students to assess their control of the target grammar and teachers to diagnose areas of difficulty; an authentic example of graduate-student writing showing the unit grammar in use; clear descriptions of essential grammar structures using the framework of functional grammar, cutting-edge research in applied linguistics, and corpus studies; vocabulary relevant to the grammar point is introduced--for example, common verbs in the passive voice, summary nouns used with this/these, and irregular plural nouns; authentic examples for every grammar point from corpora and published texts; exercises for every grammar point that help writers develop grammatical awareness and use, including completing sentences, writing, revising, paraphrasing, and editing; and a section inviting writers to investigate discipline-specific language use and apply it to an academic genre.

Among the changes in the Second Edition are:

• new sections on parallel form (Unit 2) and possessives (Unit 5)
• revised and expanded explanations, but particularly regarding verb complementation, complement noun clauses, passive voice, and stance/engagement
• a restructured Unit 2 and significantly revised/updated Unit 7
• new Grammar Awareness tasks in Units 3, 5, and 6
• new exercises plus revision/updating of many others
• self-editing checklists in the Grammar in Your Discipline sections at the end of each unit
• representation of additional academic disciplines (e.g., engineering, management) in example sentences and texts and in exercises.
