Bonjour

1- How long have the Morgan's been living in LA ?

2- When did she get here? (When did she arrive there?)

3- How long  have the children been watching TV?

4- How long have we known Robert ?

5- When did he begin to live in Bristol?

6- How long has it been snowing ?

7- How long has Mr Bristol been ill ?

8- When did they buy their new car ?

9- How long has she been  wearing glasses ?

10- When did Bob start playing the piano?

Avec how long, on garde le present perfect=> on parle d'une durée

Avec When, on utilise le past simple (preterit). ll faut donc modifier le verbe pour préciser la question. On parle du point de départ de l'action.
