This PowerPoint presentation covers the topic of subject-verb agreement. It explores some of the difficulties with subject-verb agreement and provides guidance on avoiding agreement errors. Some key points covered include: singular subjects require singular verbs and plural subjects require plural verbs; indefinite pronouns like everyone are always singular; verbs agreeing with compound subjects depend on which subject is closest; and expletive constructions have the subject come after the verb. The presentation encourages reviewing more on this topic in the Guide to Grammar and Writing.
