This document discusses subject-verb agreement and provides examples of singular and plural subjects taking the correct verb form. It explains that a singular subject takes a singular verb form while a plural subject takes a plural verb form. Examples are given of singular and plural subjects with present tense verbs. The document also notes that with pronouns like he, she, it the verb takes an -s ending in the present tense. Readers are asked to identify subjects and choose the correct verb form in several sentences. Additional examples discuss when the subject may be separated from the verb by a prepositional phrase or question word.
