　　Barbara was driving her six－year－old son，Benjamin，to his piano lesson.

　　They were late.Barbara had to drive much faster.Barbara，a night－duty nurse at the local hospital，had recently worked extra shifts.She was tired.

　　“Mom！” Ben cried.“Look！” Just ahead，a car had lost control on a patch of ice.Barbara pulled over，and threw open her door.Thank goodness she was a nurse—she might be able to help these unfortunate passengers.
