Объяснение:

Используем формулу

Подлежащее + глагол (will + have been + Participle 1).

При этом, Participle 1 - это смысловой глагол с добавлением окончания ing.

Используем данное время, когда хотим сказать, что какое-то действие начнется и будет продолжаться к определенной точке во времени в будущем.
