Key Notes:

1. What are Perfect Verb Tenses?

Perfect verb tenses show the relationship between actions and time. They focus on the completion or experience of an action in relation to the present, past, or future.

2. Types of Perfect Verb Tenses:

  • Present Perfect Tense
    • Form: has/have + past participle
    • Use: Describes actions that happened at an unspecified time in the past or actions that started in the past and continue into the present.
    • Example: “She has finished her homework.”
    • Keywords: ever, never, yet, already, just, since, for.
  • Past Perfect Tense
    • Form: had + past participle
    • Use: Describes an action that was completed before another action in the past.
    • Example: “He had left before I arrived.”
    • Keywords: already, before, by the time, when.
  • Future Perfect Tense
    • Form: will have + past participle
    • Use: Describes an action that will be completed before a specified point in the future.
    • Example: “By next week, they will have finished the project.”
    • Keywords: by, by the time, before.

3. Key Uses of Perfect Verb Tenses:

  • Present Perfect: To indicate experience or change over time.
