Gramática
Para hacer preguntas, solemos anteponer el verbo al sujeto. Esto se llama inversión.
| Affirmative | Question |
| I am late. | Am I late? |
| I can help. | Can I help? |
| She is sleeping. | Is she sleeping? |
| We have met before. | Have we met before? |
Si hay una palabra interrogativa (por qué, qué, dónde, cómo, etc.), va antes del verbo.
| Question | Question with question word |
| Are you late? | Why are you late? |
| Was she there? | When was she there? |
| Can I help? | How can I help? |
| Have we met before? | Where have we met before? |
Esto es válido para las frases con be, las frases que tienen verbos auxiliares (por ejemplo, They are waiting. She has finished.) y las frases con verbos modales (can, will, should, might, etc.).
Preguntas en presente simple y pasado simple
Para otros verbos en presente simple, utilizamos el verbo auxiliar do/does en la pregunta.
| Affirmative | Question | Question with question word |
| You work at home. | Do you work at home? | Where do you work? |
| It costs £10. | Does it cost £10? | How much does it cost? |
We use the auxiliary verb did in the past simple.
| Affirmative | Question | Question with question word |
| She went home. | Did she go home? | Where did she go? |
| They went to the cinema. | Did they go to the cinema? | Where did they go? |
Preguntas con sujeto
En algunas preguntas, quién o qué es el sujeto del verbo. En estas preguntas no hay inversión de sujeto y verbo.
