It's a book
It's a phone
It's a photo
It's a bicycle
It's a sandwich
It's a house
It's a laptop
It's a bag
It's a watch
It's a bus
It's an apple
It's an umbrella
(to ask about things)
I'm José.
It's a pencil.
(to ask about people)
It's my mother.
He's the president of Peru.
(to ask about the state of things)
I'm fine, thank you.
It's very cold!
