I have an old schoolbag. It's black. It's very big and light. My mum bought it for me on my birthday. I like it very much. But it was broken yesterday. Today mum goes to the supermarket with me. She wants to buy a new schoolbag for me. I like the yellow one. It's ninety yuan. But it's too big for me. So I take the red one. It's light and not too big for me. It's eighty yuan.
