Hi, I'm Mary. I've got a sister, [she|her|he|his] name is Diane. This is [we|our|it|its] bedroom. There [is|isn't|are|aren't] two beds in the bedroom. My bed is orange because orange is my favourite colour. I love music, and there [is|isn't|are|aren't] a guitar in the bedroom. [Where|There|They|Their] is a computer on the desk, but there isn't a TV.
