When we are talking about our abilities in the past, future or present, we often use:
| can | be able to | 
Talking about the Present
Talking about ability in the present is very simple. We use:
| subject + 'can' / 'be able to' + verb | 
Normally, we use 'can' more often than 'be able to,' because 'be able to' sounds more formal. Here is an example sentence.
| Subject | 'can' | Verb | |
| I, You, He, She, It, We, You, They | can | swim | very well. |
