Answer 1

Ao mudar uma frase em inglês para a forma interrogativa, usamos o verbo auxiliar DOES antes do sujeito para a 3ª pessoa do singular e DO para os demais pronomes pessoais.

Porém, ao se tratar do modal verb CAN, apenas o colocamos antes do pronome e continuamos a frase normalmente:

1. Could he swim in the river?
2. Can you hear me?
3. Can she work as a cook?
4. Could they do the exercises?
5. Can she drink hot coffee?
6. Can she dance very well?
7. Could she lift 100 kilos?
8. Could I speak english?
9. Can they use a computer?
10. Can I read?

Já na forma negativa, adicionamos "not" após o verbo auxiliar, mantendo a ordem original da frase:

1. He could not/couldn't swim in the river.
2. You cannot/can't hear me.
3. She cannot/can't work as a cook.
4. They could not/couldn't do the exercises.
5. She cannot/can't drink hot coffee.
6. She cannot/can't dance very well.
7. She could not/couldn't lift 100 kilos.
8. I could not/couldn't speak english.
9. They cannot/can't use a computer.
10. I cannot/can't read.
