Bonjour,
Toutes les phrases de l'exercice contiennent le modal can.
Il faut mettre les phrases soit au futur, soit au présent perfect.
Attention : can ne peut pas se mettre au futur ou au present perfect
---> il faut utiliser son équivalent : be able to ( voir consigne )
Réponse :
a. I can’t see my doctor.
( present perfect : have/has + participe passé )
be able to au present perfect : have been able to / haven't been able to
This week I haven’t been able to see my doctor.
b. He can’t go to the stadium.
( futur : will + base verbale )
be able to au futur : will be able to / won't be able to
He has got too much work: so, tomorrow he won’t be able to go to the
stadium.
c. Tom can go to the seaside.
( futur : will + base verbale )
This year Tom will be able to go to the seaside.
d. He can repair his car.
( present perfect : have/has + participe passé )
Today he has been able to repair his car.
