Bonjour,
She is able to speak four languages but she isn't able to fly a plane.
She has to wear a uniform but she doesn't have to wear a hat.
She is not allowed to be impolite with passergers.
She is lucky, she is able to fly for free.
Explications :
can/ must .... ont des équivalents qui sont : be able to / to have to /be allowed to .... Ils sont très importants surtout quand on change de temps.
Exemple :
You must do your homework ( tu dois faire ton travail )
Si je te demande de mettre cette phrase au futur tu serais obligé d'utiliser l'équivalent de must = to have to car Must ne se met pas au futur
La phrase au futur serait donc:
You will have to do your homework.
