It's Sunday morning. 9-year-old Molly is at home with her mother. She asks, "Mum,are we going to the supermarket?" Her mum says, "Dear, please wait minute. You see, I (write) a shopping list now. "

After finishing it, they walk to the supermarket near (they) home. "Look, Mum! Lots of things are sale today. They are very cheap," Molly says. Then they take a shopping cart(购物车) and start to choose things on the shopping list—five erasers, two pens and some food, such as sausages,(biscuit) and bread.

Then Molly (see) lots of candies. "Mum, I want (eat)them. Can I have some?" she asks. "No. They are not on the shopping list. And they are not (health)," her mum says. "But I (real) like them," says Molly.

"OK. But promise me that you only eat one every week," her mum says.

"I promise," Molly says happily. "Love you, Mum."
