Passage Two A particular area in which assumptions and values differ between cultures is that of friendship. Friendships among Americans tend to be shorter and less intense than these among people from many other cultures. At least many observers from abroad have this impression.Because Americans are taught to be self-reliant，because they live in a very mobile society，and for many other reasons as well，they tend to avoid deep involvement with other people. Furthermore，Americans tend to“compartmentalize”their friendships，having their“friends at work”，“friends at school”，a“tennis friend”，and so on. Americans often seem very friendly even when you first meet them. This friendliness does not usually mean that the American is looking for a deeper relationship. The result of these attitudes and behaviors is sometimes viewed by foreigners as an“inability to be friends”. Other times it is seen as a normal way to retain personal happiness in a mobile，ever-changing society. People normally have in their minds stereotypes about people who are different from themselves. Stereotypes are based on limited and incomplete experience and information，but they shape people’s thoughts and expectations. Americans have many stereotypes about foreign students in general（for example，that they are very hard working intelligent，and rich that they do speak English well）and about particular categories of foreign students（Chinese are polite and good at mathematics，for example，or Italians are emotional）. And foreign students have their own stereotypes of Americans，for example，that they are arrogant，rude，and generous. There are two stereotypes that often affect male-female relationships involving U.S. and foreign students. The first is the idea，held by some foreign males，that American females are invariably willing，if not anxious to have sex. The second common stereotype，held by some American females，is that male foreign students have no interest in American females other than having with them. The existence of these and other stereotypes can give rise to considerable misunderstanding and can block the development of a mutually satisfactory relationship between particular individuals. Stereotypes seem unavoidable given the way the human mind seeks to categorize and classify information，so it is not realistic to suppose people can“forget their stereotypes”. But they can be aware of their stereotypes，and be ready to find exceptions to them. 36. Consuming friendship，Americans .
