My sister hasn't taken a lot of photos.
They have never ridden a camel.
I have been to an arts camp before.
They haven't set their tent yet.
Have you just come?
Have you ever taken on a roller coaster?
My cousin can`t rollerblade. The boy doesn`t play computer games. They haven`t got a goldfish. It isn`t hot today. I dont`t wash the dishes. I ain`t from Britain. My friends aren`t at the cinema now. He isn`t got green eyes
He loves animals so he became a vegetarian
