MUST/MUSTN'T
We can use MUST when something is necessary. In the episode, THE QUEEN, Peppa tells the Queen:
"You MUST wear your boots when you jump in muddy puddles".
In the episode, SCHOOL PLAY, Peppa says:
"Daddy, you must not (mustn't) take photos.
CAN/CAN´T
We use CAN/CAN´T to talk about our ability to do something. In the episode MUSICAL INSTRUMENTS, Peppa asks Mummy Pig:
"Mummy, can you play the violin?
and then when she wants to try:
"Mummy, can I play the violin?"
COULD/COULDN'T
We use COULD/COULDN'T to talk about our ability to do something in the past. For example, in the episode MUSICAL INSTRUMENTS, Peppa talks about George playing the horn:
"Mummy couldn't play it, Daddy couldn't play it and even I couldn't play it, but George can play it!"
BE GOING TO
We use BE GOING TO to talk about plans and intentions we have in the future. For example, in the episode, SCHOOL PLAY, the Narrator says:
"Peppa's playgroup are going to put on a play."
"Pedro Pony is going to play Pedro the Hunter."
"Rebecca Rabbit is going to play Grandma."
Peppa says:
"I´m going to visit my Grandma."
