　　One day Ben and his mother go to Big City Supermarket and Top Value Supermarket．They go to Big City Supermarket first．

　　“List the prices of the canned foods, Ben,”his mother says．“I will list the prices of the fresh foods．”

　　Ben walks up and down the aisles(通道)．He writes down all the prices．Then he finds his mother looking at the vegetables．

　　“How much are the canned tomatoes?”his mother asks him．

　　“Two dollars,”Ben says, looking at his list．

　　“How much is the canned fish?”his mother asks．

　　“Four dollars,”Ben tells her．

　　He tells her the prices of all the canned foods, and then they go to Top Value Supermarket．They compare the prices．Most things are cheaper at Top Value Supermarket than at Big City Supermarket．Some things are more expensive．
