【答案解析】[解析] 29-31 The last area of behavior that I want to mention today is gift-giving. Everybody likes to receive gifts, right? So you may think that gift-giving is a universal custom and there's not much variation from culture to culture. But actually, the rules of gift-giving vary quite a lot, and not knowing them can result in great embarrassment. In North America, the rules are fairly simple. If you're invited to someone's home for dinner, bring wine or flowers or a small item from your country. Among friends, family, and business associates, we generally, don't give gifts on other occasions except on someone's birthday and Christmas. The Japanese, on the other hand, give gifts quite frequently, often to thank someone such as a teacher or doctor for their kindness. In the Japanese culture, as in many other cultures in Asia, the tradition of gift-giving is very ancient. There are many detailed rules for everything from the color of the wrapping paper to the time of the gift presentation. Middle easterners are also generous gift givers, both in social and business situations. And while Europeans don't generally exchange business gifts, they do follow some formal customs when visiting homes, such as bringing flowers. The type and color of flowers, however, can carry special meaning, depending on which European country we're talking about. 29. On what occasion do friends give gifts in North America?
