Очень хорошо! Вы проделали отличную работу в разборе скобок в тексте. В данном случае, мы используем Future Continuous (будущее длительное время) и Future Perfect (будущее совершенное время) для описания событий, которые произойдут после времени, указанного в предложении "On June 20th".

Future Continuous используется для описания продолжающегося действия в будущем на момент указанной даты. Например, "I will be very happy to see them again" - буду очень рад увидеть их снова.

Future Perfect говорит о действиях, которые будут уже завершены к указанной дате. Например, "I will have been away from home for two years by that time" - я буду отсутствовать дома уже два года к тому времени.

В результате, мы получаем более полное представление о предстоящих событиях, используя соответствующие формы глаголов.
