Future Continuous и Future Perfect
will be doing / will have done
Два взгляда на будущее:
- процесс в определённый момент: At 8 p.m. I will be flying to Rome.
- результат к сроку: By Friday we will have finished the report.
- длительность к сроку: By June he will have been working here for ten years.
- вежливый вопрос о планах: Will you be using the car tonight?
С Future Perfect почти всегда стоит by: by then, by the end of the week.
