5. Have locked - действие не закончено

Предлагаю смотреть на все перфекты так:

Глагол have - иметь, давай будем переводить его дословно.

Например, I haven't called you --> я не имею звонившей тебе т.е я тебе все еще не позвонила

А вот другой пример, I hadn't called you untill it was too late - я не имела звонившей тебе пока не было слишком поздно т.е Я тебе не позвонила пока не стало слишком поздно.

Заметим, что в первом примере действие имеет отношение к настоящему, а во втором идет повествование о прошлом.

Вот такой очень краткий инсайт поможет в процессе понимания этой грамматики, если конечно же интересно
