                                                                          Fair Way

     The Westborough High School golf team had taken the official photos with the state prize. The other teams,

disappointed, were on the bus heading home. And then Westborough instructor Greg Rota noticed something

wrong with one of the score cards. A 9 had been recorded as a 7. They were not the state prize winner; Wobum

High had won. "No one would have known," said Wobum's instructor, Bob Doran. For Rota, it wasn't a difficult

decision:"The prize wasn't ours to take."

                                                                          Coin Stars

     "College students are lazy, but they also want to help," says University of Pennsylvania graduate Dana Hork.

So she made it easy, placing cups in rooms where students could leave their spare coins, and handing out cups

to first-year students to keep in their rooms. Her "Change for Change" effort has collected $40,000 for charities

(慈善机构), which were decided upon by students.
