Răspuns:
My friend James has got two brothers. Their dad is a famous artist and their mum is a vet. James wants to be an actor because he loves the theatre. His brother, Paul, would like to be a firefighter or an astronaut, but he isn't tall enough, so he wants to be a police officer. And his younger brother, Michael, loves music, but he can't be singer, because he can't sing. But he plays the piano very well, so, maybe he will be a musician.
