Module 6: Perfect Continuous Tenses

The perfect simple tenses talk about completed actions in the past, present, and future. The perfect continuous tenses, also known as perfect progressive tenses, describe actions that started in the past and continue into the present or will be completed at a later time. 

Module Six focuses on the perfect continuous tenses and how to use them in the past, present, and future forms. This section provides a working definition for each, along with examples and exercises to help you understand and master each tense.
