The document discusses the differences between the present perfect simple and present perfect continuous tenses. The present perfect simple is used to describe past experiences or actions that are completed or have occurred before now. It emphasizes the result of an action. The present perfect continuous emphasizes the duration of an ongoing action that began in the past and continues in the present. It focuses on the process rather than the completion of the action. The document provides examples of how to use each tense correctly and explains the differences between since and for in the context of these tenses.
