A、They may worry about their knowledge of "yes" in the native language. B、They may worry about their ability to make friends. C、

Culture shock occurs as a result of total immersion in a new culture. It happens to people who have been suddenly transplanted abroad. Newcomers may be anxious because they do not speak the language, know the customs, or understand people’s behavior in daily life. The visitor finds that yes may not always mean yes, that friendliness does not necessarily mean friendship, or that statements that appear to be serious are really intended as jokes. The foreigners may be unsure as to when to shake hands, when to initiate conversations, or how to approach a stranger. The notion of culture shock helps explain feelings of bewilderment and confusion. Language problems do not account for all the frustrations that people feel. When one is deprived of everything that was once familiar, such as understanding a transportation system, knowing how to register for university classes, or knowing how to make friends, difficulties in coping with the new society may arise.
    Newcomers feel at times that they do not belong and consequently, may feel alienated from the native member of the culture. When this happens, visitors may want to reject everything about the new environment and may exaggerate the positive aspects of their own culture. Conversely, visitors may scorn their native country by rejecting its values and instead choosing to identify with the values of the new country.
