Can
Мы используем can, чтобы сказать, что что-то возможно или разрешено, или что у кого-то есть физическая способность что-то сделать. Мы используем can + инфинитив (can do / can see и др.):
- We can see the lake from our bedroom window.
- ‘I haven’t got a pen.’ ‘You can use mine.’
- Can you speak any foreign languages?
- I can come and see you tomorrow if you like.
- The word ‘play’ can be a noun or a verb.
Отрицательная форма — can’t (= cannot):
- I’m afraid I can’t come to the party on Friday.
(Be) able to
Вы можете сказать, что кто-то is able to (способен) сделать что-то, но can более естественный вариант:
- We are able to see the lake from our bedroom window.
Но у can есть только две формы: can (настоящее время) и could (прошедшее время). Поэтому иногда необходимо использовать (be) able to. Сравните:
◇ I can’t sleep.
◇ I haven’t been able to sleep recently.
◇ Tom can come tomorrow.
◇ Tom might be able to come tomorrow.
◇ Maria can speak French, Spanish and English.
◇ Applicants for the job must be able to speak two foreign languages.
Could
Иногда could используется как прошедшее время модального глагола can. Часто мы используем could с:
see hear smell taste feel remember understand
- We had a lovely room in the hotel. We could see the lake.
- As soon as I walked into the room, I could smell gas.
- I was sitting at the back of the theatre and couldn’t hear very well.
Мы также используем could, чтобы сказать, что кто-либо обладал общей способностью или разрешением что-либо сделать:
- My grandfather could speak five languages.
- We were totally free. We could do what we wanted. (= we were allowed to do = нам было разрешено)
Could и was able to
Мы используем could, говоря об общей способности. Но если вы хотите сказать, что кто-то сделал что-то в какой-то конкретной ситуации, используйте was/were able to или managed to (not could):
- The fire spread through the building very quickly, but fortunately everybody was able to escape / managed to escape. (not
could escape) - We didn’t know where David was, but we managed to find / were able to find him in the end. (not
could find)
Сравните:
Mike was an excellent tennis player when he was younger. He could beat anybody. (= в общем, у него была способность/возможность победить кого угодно)
но
Mike and Pete played tennis yesterday. Pete played very well, but Mike managed to beat him. (= он смог победить его конкретно в этой игре)
Отрицательная форма couldn’t (could not) возможна во всех ситуациях:
- My grandfather couldn’t swim.
- We looked for David everywhere, but we couldn’t find him.
- Pete played well, but he couldn’t beat Mike.

Can and could are modal auxiliary verbs which express ability, permission, request, offer or possibility.
Could is originally the past form of can, but it also has certain functions which can does not, for example, it is used in hypothetical conditions.
Examples:

- It could rain this afternoon. (possibility)

- We could get there in time if you were driving a bit faster. (hypothesis + ability/possibility)
Can and could are also used to express the progressive (continuous) aspect of verbs of perception (see, hear, feel, taste, smell, etc.) and verbs like understand, remember, etc:
Examples:
- Can you see the woman standing over there?

- When she entered the kitchen, she could smell something burning.
- I put my keys to a safe place before swimming, but now I can’t remember where.

As the past form of can, could is used for general ability in the past and in reported speech.

- You can go now if you want to.
- Can I stay here for another hour? – No, I’m afraid you can’t.
