Выражение способности, возможности

Способность или возможность совершения какого-либо действия выражается при помощи модального глаголаcan, его эквивалента to be able (to) и выражения managed (to).
1. To be able (to) означает то же, что и can, но can употребляется намного чаще. To be able (to) более официален.
Can you come to a meeting next week? Ты сможешь прийти на собрание на следующей неделе?
Please inform us if you are able to attend a meeting next week. Пожалуйста, сообщите нам, сможете ли Вы присутствовать на заседании на следующей неделе.
2. Was/were able (to)используется для выражения единоразового действия в определённой ситуации или повторяющихся действий в прошлом.

I was able to go on a trip round the city last week. Я смог (мне удалось) поехать на экскурсию по городу на прошлой неделе. (единоразовое действие)

Для выражения единоразового действия в прошлом также может использоваться выражение managed to. I managed to get up early today.

Could используется для выражения способности/возможности повторяющихся действий в прошлом иупотребляется чаще, чем was/were able (to).
I could swim when I was four. Я умел плавать, когда мне было четыре года.

Have /has been able toиспользуется в Present Perfect: I have been able to swim since I was four. Я умею плавать с четырех лет.

Исключением данного правила являются глаголы чувства и восприятия. С такими глаголами употребляется модальный глагол could.

Примечание: Can и can't могут использоваться для выражения будущего действия, если говорящий решает в момент разговора (то есть наверняка знает) что cможет или не сможет совершить его.
