For many     36   in the US, earning some money gives them a sense of    37    . By making their own money they can buy whatever they want . It also develops a sense of responsibility and independence .
Most teens I know have a small sum of money . Their   38     give them an allowance (零用钱). For some ,an allowance is given every week ; for    39    , every month or so . Usually they can get 10 to 30 dollars a month from their parents .
