Lo primero que tienes que recordar sobre los verbos modales
es que no cambian según el tiempo verbal (deben tener
sustitutos para esto) y que el verbo principal que los sigue se
usa sin preposición “to”: “can”, “play”, “must pay”, “would go”,
etc. En las oraciones, estos verbos modales tienen la función de
un verbo auxiliar: “Can you swim?”. ¿Puedes nadar? “Would you
play?”. ¿Jugarías? “May I go?”. ¿Puedo ir?
Hoy vamos a echar un vistazo
a las reglas sobre el uso de los
verbos modales “must”, “have
to”, “may” y “might”.
The golden rules to use modal verbs correctly
we will see three essential rules to
correctly use modal verbs
Cómo se pronuncia They are always
followed by an infinitive verb, since they
have no meaning for themselves.
Normally this verb does not lead to,
although there are some exceptions that
are also considered modal verbs: be able
to, need to, have to and ought to.
They do not conjugate, that is, they do not add
-s in the third person singular and have no past
or future. Nor do they have infinitive,
compound or progressive times.
In interrogative and negative forms,
they do not need to add the auxiliary
(do or does). For example: Can you
come with me tomorrow?
