Sam: I am a Nike fan. Many of Nike's advertisements are fun and its products are great! I have a pair of Nike basketball shoes.
Joe: In my eyes, top brand means high quality, So I love top brand products though they're very expensive. I was glad Mum bought me a Kappa T-shirt last month.
Sally：The logos(标识) of famous brands are usually unique and nice. It's cool to own products with those logos. Sometimes I wear my adidas coat.
Jack：Many top brand products are advertised by spokesmen(代言人). I love the spokesmen of many top brand products. I've got many Nike socks.
Susan: I know it's popular for young people to have famous brand products these days. But my parents both lost their jobs. I have no interest in following the fashion. I only choose the products that are not expensive.
Adam: As a student, I don't earn money myself. It's not easy for my parents to support me. So I only use some ordinary products. I don't agree students use the famous brand products.
