Урок 9 (B2): Модальные глаголы в прошедшем времени для выражения предположений

Привет! В предыдущем уроке мы освоили сложные пассивные конструкции. Сегодня мы погружаемся в увлекательный мир модальных глаголов в прошедшем времени — мощный инструмент для выражения предположений, вероятности и логических выводов о прошлых событиях.

Представьте, что вы — детектив, который анализирует улики и делает выводы о том, что могло произойти. Модальные глаголы в прошедшем времени — это ваш инструментарий для выражения различных степеней уверенности:

• Must have = "Я почти уверен, что это произошло" (95% уверенности)
• Could have = "Возможно, это произошло" (50% уверенности)
• Might have = "Может быть, это произошло" (30% уверенности)
• Can't have = "Я уверен, что это НЕ произошло" (95% уверенности)

Эти конструкции незаменимы для:

• Анализа прошлых ситуаций
• Выражения сожаления и критики
• Логических умозаключений
• Вежливых предположений
• Создания атмосферы неопределенности в рассказах

На уровне B2 владение этими структурами показывает способность к сложному логическому мышлению на английском языке. Готовы стать языковыми детективами? Начинаем расследование!

👥 Практические диалоги

Диалог 1: Расследование пропажи

Detective: The witness says she saw someone leaving the building around midnight. Who could that have been?

Sergeant: It must have been the janitor. He usually works late shifts.

Detective: But the janitor was sick yesterday. He couldn't have been at work.

Sergeant: Then it might have been one of the tenants. Could someone have forgotten their keys and come back?

Detective: Possible, but the security cameras should have recorded anyone entering after 10 PM.

Sergeant: The cameras weren't working. The thief must have known about the malfunction.

Detective: Or it could have been just a coincidence. But that seems unlikely.

Sergeant: The lock wasn't forced. Whoever it was must have had a key.

Detective: That narrows it down significantly. It could have been someone with authorized access.

Sergeant: Should we have checked with the building management about who has keys?

Detective: We already did. Three people could have been responsible: the manager, the security guard, and the cleaning lady.

Sergeant: The cleaning lady might have been there, but she should have signed the log book.

Диалог 2: Обсуждение неудачной презентации

Manager: The client meeting didn't go well yesterday. What do you think went wrong?

Sarah: The presentation could have been better prepared. We should have spent more time on the slides.

Manager: The technical issues didn't help either. The projector shouldn't have failed at such a crucial moment.

Tom: That must have been embarrassing. Could we have tested the equipment beforehand?

Sarah: We should have, but there wasn't enough time. The client might have been more understanding if we had explained the situation better.

Manager: Could the outcome have been different if we had rescheduled?

Tom: It might have been, but the client couldn't have waited another week. Their deadline was firm.

Sarah: The competitor must have made a strong impression. They could have prepared for months.

Manager: We shouldn't have underestimated their capabilities. They might have known about our proposal in advance.

Tom: Could there have been a leak of information? Some details seemed too coincidental.

Manager: That's possible. We should have been more careful about confidentiality.

Sarah: What should we have done differently to win this contract?

Диалог 3: Анализ дорожной аварии

Police Officer: Can you tell me what you saw?

Witness 1: The red car must have been speeding. It couldn't have stopped in time.

Police Officer: Could the driver have been distracted by something?

Witness 1: He might have been on his phone. I saw him looking down just before the collision.

Witness 2: The traffic light should have been yellow when he entered the intersection.

Police Officer: Could you have been mistaken about the timing?

Witness 2: I might have been, but I'm pretty sure it was red when the accident happened.

Police Officer: The other driver must have had the right of way then.

Witness 1: Yes, she couldn't have avoided the collision. She must have been terrified.

Police Officer: Could weather conditions have contributed to the accident?

Witness 2: It might have been a factor. The road could have been slippery from the morning rain.

Police Officer: Both drivers should have been more cautious in these conditions.

Witness 1: The red car driver must have realized his mistake. He could have prevented this if he had been paying attention.

Police Officer: Should we have seen this coming? There might have been warning signs of dangerous driving.
