Grammar Study. Времена группы PerfectВремена группы Perfect
Группа совершённых времён (Perfect Tenses) обозначает, что действие закончилось, завершилось к определённому моменту в настоящем, прошедшем или будущем: I have seen this film (Я (уже) посмотрел этот фильм). He had finished his work by 10 o’clock in the morning (Он завершил работу к 10 часам утра). Ann will have written her article by 3 o’clock. (Анна напишет статью к 3 часам). В центре внимания – результат действия, а не время его выполнения. Сказуемое во временах группы Perfect образуется при помощи вспомогательного глагола to have в настоящем (have, has), прошедшем (had) или будущем (shall have, will have) неопределённом времени и III формы смыслового глагола. Запомните порядок слов в различных типах предложений во временах группы Perfect, приведённых в таблице. Здесь, как и во временах группы Continuous, при постановке вопроса на первое место ставится первый вспомогательный глагол.
