7.I took this photo of my family last summer. My two brothers are on the left - Frank and Tim. Frank's the one with the curlier hair and he's a bit shorter than Tim. That's my sister Anne on the other side - she's standing next to her friend Lisa. You can see they're both tall and they've got the same hair style. Lisa always wears more expensive clothes than Anne, but I think Anne always looks happier. Then there's Dad here - he's playing cards with Uncle Bill. Dad's younger than Uncle Bill but he looks older and he's a bit fatter. And you can see he's winning the game because he's a better card player. So that's everyone. Oh, there are the cats too. The big one's called Sandy. She's a bit boring - she just sleeps most of the time. The little one with Uncle Bill is friendlier and more interesting - he's called Pablo.

Alan's TV is more modern than Peggy's. His window is smaller and the street outside his room is busier and noisier. Peggy's chairs are older but more comfortable than Alan's. Outside her room, she's got a lovely garden and it is quieter. Her window is bigger.
