How wonderful! You’re really lucky!” Does this sound familiar? Perhaps your family and friends said similar things to you when you left home. But does it seem true all the time? Is your life in this new country always wonderful and exciting? A great many facts show that it’s not easy for newcomers to adjust to life in a new culture. They have to experience culture shock. What causes culture shock? Maybe the weather is unpleasant.  Perhaps the customs are different. Perhaps the public service systems such as the telephone, post office, or transportation are difficult to figure out and you make mistakes. The simplest things seem difficult. The language may be difficult. The food may seem strange to you. If you don’t look similar to the natives, you may feel strange. You may feel as ff everyone is watching you. In fact, you are always watching yourself. Everyone experiences culture shock in some form or another. But culture shock comes as a surprise to most people. A lot of the time, the people with the worst culture shock are the people who never had any difficulties in their own countries. They were active and successful in their community(社区). They had hobbies or pastimes which they enjoyed. When they come to a new country, they do not have the same positions or hobbies as they already had in their countries. They find themselves without a role, almost without an identity. They have to build a new self-image. Culture shock produces a feeling of disorientation(晕头转向), which may be homesickness, imagined illness, or even paranoia(偏执症). When people feel the disorientation of culture shock, they sometimes feel like staying inside all the time. They want to protect themselves from the unfamiliar environment. They want to create an escape within their room to give themselves a sense of security. This escape does solve the problem of culture shock for the short term, but it does nothing to familiarize the person more with the culture. Familiarity and experience are the long-term ways to settle the problem of culture shock. 67. Who is the passage mainly for? A. The family and friends of those who came to the US. B. Those who have got rid of culture shock. C. People who have just moved to a foreign country. D. People who can easily adjust their life in the US. 68.
