1. Overview: The future perfect passive voice is used to talk about actions that will have been completed by a certain point in the future. It emphasizes the action and the object of the action rather than the subject. This form is often used to discuss plans or expectations. Structure: "will have been" + past participle.
2. Cases of Usage:
- To express an action that will be completed before a specific future time.
Example: The report will have been finished by Friday.
- To indicate an action that will be completed before another action in the future.
Example: The house will have been sold before the end of the month.
- To show certainty about a future completion.
Example: By next year, the project will have been completed.
3. Exceptions or Things to Pay Attention To:
The future perfect passive voice is not commonly used when the focus is more on the subject rather than the action or object. In spoken language, people might prefer the active voice even when the passive would be grammatically correct.
Example: Instead of saying, "The pizza will have been delivered," one might simply say, "They will have delivered the pizza."
4. Additional Notes: Common mistakes include using the wrong form of "to be" or forgetting to use "have" with the past participle.
