TO BE [=ser, estar…]
Como todos los verbos auxiliares, para hacer la negativa se le añade NOT y para la interrogativa basta con cambiar el orden (en lugar de Sujeto + Verbo, ponemos Verbo + Sujeto?).
Simple Present
|I am (I’m) |I'm not |Am I? |
|You are (You’re)|You aren't |Are you? |
|He/She/It is (He’s/ she's/ It's) |He/she/it isn't |Is he/she/it? |
|We are (We’re) |We aren't |Are we? |
|You are (You’re) |You aren't|Are you? |
|They are (They’re) |They aren't |Are they? |

|He/She/It was |He/She/It wasn't |Was he/she/it? |

THERE BE [=haber impersonal: "hay", "había"…]

Nota: funciona igualque el verbo TO BE, pero colocando el pronombre impersonal «there» como sujeto, tanto en tiempos compuestos:
"There has been enough money"
como con verbos modales:
"There must be a reason".
