| This is part three of our survey about family life. We interviewed two students, Josh Franklin and Alice Gomez, about their weekend chores. They told us about the chores they did last weekend. On Saturday morning, Josh had two big chores to do. He didn't like washing the clothes, but he enjoyed cleaning the garage (汽车房). "I listened to the radio and sang my favorite songs while I worked," he said. Alice had to go to the store and buy food for the family on Saturday morning. Her mother usually goes with her, but this time she went alone. "I liked shopping for food. I bought things I liked to eat and my parents paid for it." Josh and Alice both liked helping with their parents yard sales. "I liked talking to all the people," said Josh. Alice said, "My parents gave me part of the money. Now I can buy anything I want." | |||||||||
