This document provides an overview of verb tenses in English. It begins by defining what a verb tense is, noting that a verb tense indicates time through changes in verb form. It then categorizes tenses based on time frame (present, past, future) and aspect (simple, continuous, perfect, perfect continuous). A block diagram shows the 12 possible verb tenses. Each tense is then defined with examples, including present indefinite, present continuous, present perfect, past indefinite, past continuous, future indefinite and future continuous. The document concludes with a homework assignment asking the reader to write about their daily life using the simple present tense.
