Sure, I can help clarify how to use the future perfect and future perfect continuous tenses for your sentences. These tenses are used to describe actions that will be completed at some point in the future or that will continue up until a certain time. Here’s how you can complete your sentences:
I will have finished (finish) painting your room by the time you get home.
- In this sentence, "will have finished" is used in the future perfect tense because it talks about completing the action of painting by a specific future time.
By the end of next month I will have been living (live) in London for exactly three years.
- Here, "will have been living" is used in the future perfect continuous tense to indicate that the action of living in London will continue over a period, ending at a specific point in the future.
Tom will have written (write) his third novel by the end of this year.
- "Will have written" is in the future perfect tense because it describes the completion of the action of writing his third novel by a future date.
By the time he arrives in London, John will have been driving (drive) for five hours.
- "Will have been driving" is used in the future perfect continuous tense to show that John’s driving will continue until it reaches a duration of five hours by the time he arrives in London.
This film will probably not have finished (probably / not / finish) until midnight.
- "Will probably not have finished" is in the future perfect tense, indicating that the film is unlikely to be finished before midnight.
These structures are very useful for emphasizing the completion or duration of actions relative to a future moment.
