Can, Could, Can't, Couldn't

What's up?

In this class, we're going to teach you the verb Can, its past and present forms, and also de negative form. We call thi kind of verb a Modal Verb. Pay close attention to it:

> The Verb Can, differently from other verbs, doesn't take the word "to", neither before nor after it. It expresses abilities and/or capabilities.
Also, for the third people singular (He/She/It), we don't add -s, -es or -ies.
Giba can play volleyball very well.
Africans can run the marathon better than anybody else.

Its negative form is Can't or Cannot:
Shaquile O'neil can't play basketball so well anymore.

In a question, Can comes before the subject:
Can you throw the discus?
What position can they play?

> Could expresses abilities and/or capabilities in the past. Its negative form is Couldn't.

In questions, Could comes before the Subject:
Mark Spitz could swim like a fish.
Could Airton Senna speak English?
couldn't swim at all when I was a child.

+ We can use some adjectives to intensify the verb. Observe:
I couldn't swim at all. - No chance for you to do that.

0%     - not at all
20%   - a bit/ a little
40%   - quite well/ fairly well
60%   - pretty well
80%   - very well
100% - extremely well

Rodrigo Pessoa can ride a horse pretty well.
Zico could play soccer extremely well.

Na aula de hoje, ensinarei o Verbo Poder, no passado e o presente, e sua forma negativa. Preste muita atenção:

> O Verbo Can (Poder, Conseguir), diferentemente dos outros verbos, não aceita o "To", nem antes, nem depois dele. Ele expressa habilidades e/ ou capacidades.
Para a terceira pessoa do singular, não usamos terminação em -s.
Giba can play volleyball very well.
Africans can run the marathon better than anybody else.

A Forma Negativa é Can't ou Cannot:
Shaquile O'neil can't play basketball so well anymore.

Em perguntas, Can vem antes do sujeito:
Can you throw the discus?
What position can they play?

> Could expressa habilidade/ capacidade no passado. A forma negativa é Couldn't. Pode significar Poderia, Pude, Pôde, Pudesse...

Em perguntas, Could vem antes do sujeito:
Mark Spitz could swim like a fish.

+ Podemos usar alguns advérbios para dar intensidade ao verbo. Observe:
Quando você não pode fazer alguma coisa de nenhum jeito, você pode usar o advérbio "at all":
I couldn't swim at all.
