Adam often goes shopping with his mother. His favorite shops are the supermarkets， because they are big and bright and full of different things.

Adams mother does the shopping very carefully. She goes to different supermarkets and compares their prices. Adam helps her.

Last time they went shopping， Adam and his mother went to Big City Supermarket and Top Value Supermarket. They went to Big City Supermarket first.

“List the prices of the tinned foods， Adam，” his mother said. “Ill list the prices of the fresh foods.”

Adam walked up and down the aisles. He wrote down all the prices. Then he found his mother looking at the vegetables.

“How much is the tinned milk powder？” his mother asked him.

“Three pounds，” Adam said and looked at his list.

“How much is the tinned fish？” his mother asked.

“Two pounds，” Adam told her.

He told her the prices of all the tinned foods， and then they went to Top Value Supermarket. They compared the prices. Some things were cheaper at Top Value than at Big City. Some things were more expensive.
