This document discusses different types of verbs. It explains that every sentence contains a subject and a predicate, with the verb being the key word in the predicate. Verbs can express either action or being. Action verbs refer to physical or mental actions, while being verbs express a state of being and do not involve action. Some verbs can function as either linking verbs or action verbs depending on how they are used in a sentence. The document provides examples of sentences containing different verb types and asks the reader to identify the verbs.
