Los Modales (6)
Tener que ( have to)
En Inglés usamos have to y don’t have to para referirnos a obligaciones, ya sean
en el presente o en el futuro.
I.
have to expresa una obligación, usualmente impuesta.
Students have to read one book in English this year.
Los estudiantes tienen que leer un libro …
II.
sin embargo, don’t have to expresa “ausencia de obligación”, es decir, que
no es necesario hacer lo que sea.

NOTA: Fíjate en que mustn’t y don’t have to no significan lo mismo.
Mustn’t indica prohibición.

Don’t have to indica ausencia de obligación. I don’t have to go to school today.
NOTA: Acuérdate de que have to es un semi-modal y, por lo tanto, puede conjugarse.
