单项选择题

Culture shock is the loss of emotional balance, disorientation(方向障碍), or confusion that a person feels when moving from a familiar environment to an unfamiliar one. When it is a common experience, the degree to which it occurs will vary from one person to another. Individual personality, previous cross-cultural experience, and language proficiency all affect a person"s ability to interact socially in the new culture. The basic cause of culture shock is the abrupt loss of all that is familiar, leading to a sense of isolation.
When an individual enters a strange culture, all or most of those familiar signs and hints are removed. He or she is like a fish out of water. No matter how broad-minded or good-willed he may be, a series of properties have been knocked from under him. This may be followed by a feeling of frustration and anxiety. People react to the frustration in much the same way. First they reject the environment which causes the discomfort: "The ways of the host country are bad because they make us feel bad."
Another aspect of culture shock is regression(倒退). The home environment suddenly assumes a tremendous importance, and everything becomes irrationally glorified. All difficulties and problems are forgotten and only the good things back home are remembered. It usually takes a trip home to bring one back to reality.
Common symptoms of culture shock include the following extremes. There are excessive concerns over delays and other minor frustrations; fear of being cheated, robbed or injured; sleeplessness or a desire to sleep more; and a great longing to go home. Underlying all these is the uncomfortable feeling of not really belonging, of being an outsider.

A．difficulties in using the language
B．being unable to make new friends
C．severe homesick
D．being far away from all that is familiar
