What are the differences in choosing address forms between Chinese people and American people?
【正确答案】：Whenever people speak to one another, they have to choose the most appropriate way to address their interactants. The addressing options differ greatly across cultures.
When addressing a stranger, Chinese people often use such expressions as “lao daye” (aged uncle), “lao dama” (aged aunt) or “lao shifu” (aged master) to draw the stranger's sympathetic attention. But American people would simply use “Excuse me” in the similar circumstances.
American people usually use “Mr” or “Miss” in most formal cases, yet Chinese people would make more subtle distinctions. Suppose a person happens to be the head of a bureau (“ju” in Chinese), then he might be called “Li Ju” (Bureau Li) rather than “Li Xiansheng” (Mr Li). In contrast, there are only a few cases in English where the occupation could be used as address forms, such as “Professor Li” and “Doctor Li”.
