Привет! Давай разберёмся с твоим заданием.
Нужно выбрать правильное время для каждого предложения: Present Perfect или Past Perfect. Давай посмотрим, что у тебя уже есть и что можно сделать:
"He wondered who had brought the puppy to the classroom." - уже правильно, здесь используется Past Perfect, потому что действие произошло до другого действия в прошлом.
"I (just to finish) my test by 3 p.m. when I got a call." - "I had just finished my test by 3 p.m. when I got a call."
"By 3 p.m. Derek (to water) the garden." - "By 3 p.m. Derek had watered the garden."
"They (to leave) the building before the rain (to begin)." - "They had left the building before the rain began."
"Girls said mother (to live) in Moscow (live) when she was a child." - "Girls said mother had lived in Moscow when she was a child."
"He told me he (to write) three books when he was 60." - "He told me he had written three books when he was 60."
"When we came to the cinema, the film (to begin)." - "When we came to the cinema, the film had already begun."
Вот так твои предложения теперь выглядят правильно. Надеюсь, это поможет! Если есть другие вопросы, спрашивай. 😊
