Predictions, may/might

PREDICTIONS
When we want to say what we think will happen in the future in English, we can either use will followed by the verb without to, or going to followed by the verb.

"What do you thinkwill happen next year?"
"Next week is going to be very busy, I think."
"There won't be a rise in house prices next year."
"He isn't going to win the election."
Because we also use will to talk aboutintentions and strong decisions, we often use going to to sound less emotional.
"He won't help us" can mean that he has decided not to help us. But "He isn't going to help us" doesn't have thisnegative implication. It sounds more like a prediction and a simple, non-emotional fact- perhaps he isn't able to help us.
Predictions based on what you know now
We can make predictions based on what wecan see now. To do this, we use going to and the verb (not will).
For example:
"Watch out! You're going to hit that car in front."
"It's going to be a lovely day today – not a cloud in the sky."MAY/MIGHT
Otro de los verbos modales que se utilizan frecuentemente en el idioma inglés es MAY, un verbo que es empleado para hacer referencia a una situación hipotética, es decir que puede serposible, por ejemplo:
They may forgive me. Ellos pueden perdonarme.
She may decide to travel to Spain. Ella puede decidir viajar a España.
He may accept your request. Él puede aceptar tu pedido.Observe en los ejemplos superiores que cuando utilizamos la palabra "puede" nos referimos a una probabilidad y no a la capacidad de hacer algo, ya que en tal caso utilizaríamos el verbo modal CAN.

Elverbo modal MAY se encuentra relacionado estrechamente con MIGHT dado que ambos tienen el mismo uso y significado, aunque MAY indica un grado mayor de certeza, por ejemplo:
She may forget theproblems. Ella puede olvidar los problemas.
She might forget the problems. Ella podría olvidar los problemas.
You may pay the bills. Tú puedes pagar las cuentas.
You might pay the bills. Tú podrías...
