Wang Hong is a friendly girl and has a lot of hobbies. She often helps her parents with the housework. It’s her birthday this Saturday. Many classmates will go to her home for her birthday party. Some of them will ask their parents for some money to buy her gifts. But I don’t think it’s a good idea, because that’ll cost our parents’ money. I’m going to make a birthday card for her by myself. I’m sure she’ll like it.
