En inglés no hay tiempo futuro: las frases con verbos finitos solo se marcan para el presente y el pasado. Por lo tanto, cuando hablamos de "futuro", nos referimos a un concepto más que a una categoría gramatical
present tense forms
are used when
future events are
considered to be
relatively close or
considered to have
some connection to
the present
moment.
FORMS
affirmative:
I/weshall/will;
you/he/theywill + bare
infinitive
negative: I/we
shall/will not;
you/he/they will
not + bare infinitive
contractions: ’ll for
shall and will;
shan’t for shall not;
won’t for will not
interrogative:
shall/will I ... ?; will
you/he/they ...? +
bare infinitive
The future simple is used to make predictions
about the future and to give or ask for
information regarding future events: The
ceremony will be simple but moving He’ll be
back in an hour Will she be at the party?
Predictions can also be used as a way of
giving orders, as the following examples
show: You’ll take care of the publication
of the conference proceedings You will
finish work at 5.30 p.m.
The future simple is also used, in the
main clause, in time and conditional
sentences. Of course, the condition
does not necessarily have to be
explicitly expressed: I’ll give you a call
when they get here If I pass the test,
I’ll buy you all a drink You’ll be fired (if
you don’t work harder)
