This document provides information about common English verbs. It discusses the verbs "to be", "to have", and "to do" and how they are used in the present continuous, past continuous, and present perfect tenses. It also distinguishes between regular and irregular verbs. Regular verbs follow a consistent pattern of adding "-ed" in the past tense and past participle, while irregular verbs do not follow this pattern and must be memorized. Several examples of irregular verbs such as "be", "run", "buy", and "see" are given to illustrate this concept.
