Could assistir ao vídeo Lesson 4 Could é o passado de can: I could swim when I was 10 - Eu sabia nadar quando eu tinha 10 anos. I couldn't go there - Não pude ir lá. Could também pode ser 'poderia': Could you give me your name? - Poderia me dar seu nome? Attention: 'Eu pude ir lá': 'I was able to go there'. Porque, como você viu acima, I could significa 'eu poderia' quando não significa 'eu sabia'. Não se preocupe com esse detalhe em frase negativa. Em negativas could tem as mesmas características que can.
