[单项选择]Informal conversation is an important part of any business relationship. Before you start a discussion, however, make sure you understand which topics are suitable and which are considered taboos (禁忌) in a particular culture. Latin Americans enjoy sharing information about their local history, art, and customs. They expect questions about their family and are sure to show pictures of their children. Yon may feel flee to ask similar questions of your Latin American friends. The French think of conversation as an art form, and they enjoy the value of lively discussions as well as disagreements. For them, arguments can be interesting-and they can cover pretty much or any topic-as long as they occur in a respectful and intelligent (智慧的) manner.
In the United States, business people like to discuss a wide range of topics, including opinions about work, family, hobbies, and politics. In Japan, China, and Korea, however, people are much more private. They do not share much about their thoughts, feelings, or emotions because they feel that doing so might take away from the harmonious (和谐的) business relationship they’re trying to build. Middle Easterners are also private about their personal lives and family matters. It is considered rude, for example, to ask a businessman from Saudi Arabia about his wife or children.
As general rule, it’s best not to talk about politics or religion (宗教) with your business friends. This can get you into trouble, even in the United States, where people hold different views. In addition, discussing one’s salary is usually considered unsuitable. Sports is typically a friendly subject in most parts of the world, although be careful not to criticize a national sport. Instead, be friendly and praise your host’s team.The author considers politics and religion （）.
