The document summarizes the differences between the present simple and present continuous tenses in English. The present simple is used for habitual or repeated actions, general truths, and permanent situations. The present continuous is used for actions happening now, temporary situations, and changing situations. Some stative verbs like think, know, have, see can be used in the present continuous to indicate actions rather than states. The document provides examples and exercises to illustrate the proper uses of each tense.
