A：I actually applaud the idea and wish that more people did it. I keep a toothbrush and toothpaste in my desk all the time so I can brush after meals and breaks。
C：牙医告诉我，一天早晚刷两次牙就行了。
A：That's enough if your only goal is good dental care and the prevention of problems. Brushing on the job has a different purpose。
C：除了保护牙齿，刷牙还有其他目的？一会儿吃饭时你一定要告诉我！
A：Sure. I'll see you at the China Café。
中午吃饭时。
C：Amy, 上班时刷牙还有其他目的吗？
A：It's important for the simple reason that bad breath is offensive. Sometimes we don't realize when our mouth odor is unpleasant。
C：噢，原来是为了防止口臭。别人真能闻到吗？
A：I had a colleague once who lost his job because of his bad breath. His clients were continually offended and several asked his boss to tell him。
C：老板有没有找你那位同事谈话呢？
