We like our teacher, and they enjoy their trip.
This is not my book. That is not her bag.
It isn't his pen, and they aren't our keys.
Is this your pen? Is that his hat?
What is her name? Where are their friends?
Is this your book? Yes, it is.
Is that her bag? No, it isn't.

Sofía is a designer. She loves her job in Medellín. Her friend Ben is British; he lost his hat on his trip. Kenji is their other friend. He is from Japan, and his family lives in Tokyo. 'Is this your hat, Ben?' asks Sofía. 'No, it isn't,' he says. They laugh, because their English class is always fun.
