My name [is|are|am|isn't] Julia, and I want to show you a picture of my family. Let's have a look!

We are in the park, and we[is|are|isn't|aren't] all so happy! My brother Marcus[are|aren't|is|isn't] sitting next to our dad. I [isn't|are|aren't|am] ten, and Marcus is only seven. He is a clever and kind boy.

Our grandparents are on the left. Their names [are|am|is|isn't] Paula and Stephan. They are both smiling.
