    Não entendi: acima fala que:

    Presente = CAN
    Passado – be able (was, were)
    Futuro – be able (will)

    No entanto, no meu livro de inglês os exemplos para uso do TO BE ABLE TO, são:

    I can go with you – I’m able to with you
    you can drive there – You’re able to drive there
    He can see you tonight – He’s able to see your tonigh.

    Alguém pode me esclarecer?
    um abraço.

    Nossa, eu não sabia disso. Costumo usar o be able to, mas nunca havia relacionado com alguma regra. Muito bom!

    Sérgio,
    Não se usa CAN para descrever uma habilidade passada ou futura, então usa-se “be able to”.

    Abraço

      E o could não seria o passado do verbo can? Fiquei na dúvida.

      Camila Oliveira diz:

      Hey Indira, how are you?

      Sim, você está certa, o could é passado do Can e será utilizado para falar sobre habilidades passadas. O be able to será para habilidades futuras.

      See ya!

    Refresh my mind, pls

    Is it correct I say: I missed the bus?
    I learnt: I lost the bus, because miss is normally for feelings expression.

    Hi, everybody!
    Parabéns pelo site

    Percebi que mesmo dentro do tema abordado, muitas perguntas feitas nos comentários não são respondidas.
    Entendo que nem sempre temos tempo para atender cada uma das perguntas.
    Eu gostaria de saber se existe outro local para consultar as dúvidas deixadas aquí nos comentários, e se tem pessoas responsáveis por essa tarefa.

    Bye!

    A todos que não foram respondidos:

    ==Can, could and be able to

    a) We use ‘can’ (do) to say that something is possilbe or that someone has the ability to do something. The negative is ‘can’t’ (cannot).
    —You can see the sea from our bedroom window.
    —Can you speak any foreign languages?
    —I’m afraid I can’t come to your party next Friday.

    ‘Be able to’ is possilbe instead of ‘can’, but ‘can’ is more usual:
    —Are you able to speak any foreign languages?

    But ‘can’ has only two forms: can (present) and could (past). So sometimes you have to use be able to:
    — I haven’t been able to sleep recently. (‘can’ has no present perfect)
    — Tom might not be able to come tomorrow. (‘can’ has no infinitive)

    b) ‘Could’ and ‘was able to’
    Sometimes ‘could’ is the past of ‘can’. We use ‘could’ especially with these verbs:
    see – hear – smell – taste – feel – remember – understand
    — When we went into the house, we could smell burning.
    — She spoke in a low voice but I could understand what she was saying.

    We also use ‘could’ to say that someone had general ability to do something:
    — My grandfather could speak five languages.
    — When Tom was 16, he could run 100 metros in 11 seconds.

    But if you mean that someone managed to do something in one particular situation, you have to use ‘was/were abel to’ (not ‘could’):
    The fire spread through the building very quickly but everyone was able (= managed) to escape (not ‘could escape’)
    — They didn’t want to come with us at first but in the end we were able (= managed) to persuade them. (not ‘could persuade’)

    Compare ‘could’ and ‘was able to’ in this example:
    — Jack was an excellent tennis player. He could beat anybody. (= He had the ability to beat anybody.)
    — But once he had a difficult game against Alf. Alf played very well but in the end Jack was able to beat him. (= He managed to beat him in this particular game.)

    The negative ‘couldn’t’ is possible in all situations:
    — My grandfather couldn’t swim.
    — We tried hard but we couldn’t persuade them to come with us.

    Uma frase que eu li certa vez em um site britânico, explica uma coisinha que muita gente confunde:

    “People are able to do things, but things are not able to be done”.

    (Pessoas estão “able to” fazer coisas, mas as coisas não estão “able to” ser feitas.)

    ou seja:

    “I could be able to speak English fluently, but my English would never be able to be fluently spoken.”

    (Eu poderia estar “able to” falar inglês fluentemente, mas meu inglês nunca estaria “able to” ser falado com fluência.)

    Did someone get it? :P
