Объяснение:

В настоящем времени - can - могу, умею. I can run - Я умею бегать. Синоним от can - to be able to, имеет значение могу, в состоянии сделать что- то( после перелома, болезни, есть время свободное). Вместо to be в предложении будет am, is, are - зависит от подлежащего. I am able to play football today ( нога не болит уже) She/ He is able to sing today ( горло не болит)

В прошедшем времени вместо can - could. I could read when I was 6. Я умел читать, когда мне было 6 лет. Также можно употребить to be able to...в прошедшем времени. I was able to play football yesterday - вчера я мог играть в футбол ( а до этого- нет мог). They were able to meet her at the station.- они смогли встретить ее на станции.

В будущем времени можно употребить только to be able to, будет так: We shall be able to meet her. Мы сможем встретить ее. He will be able to explain everything. Он сможет все обьяснить.
