The next day, Dad gave Biff, Chip and Kipper some extra pocket money. "May we do what we like with it?" asked Chip. "Of course you can," said Dad. "Then we'll give it to Biff," said Kipper.

I learned importance of money to work a part-time job. Vocabulary cove:入江、小弯 fossil:化石 Hunt, R,& Brychta, A. (2011). Pocket Money . Oxford Reading Tree
