     Culture shock has many stages. Each stage can appear only at certain times. Culture begins with the

" honeymoon". This is the period of time when we first arrive in which everything about the new culture

is strange and exciting. This honeymoon stage can last for quite a long time. Afterwards, the second stage

presents itself. A person may encounter some difficult times in daily life. This period of culture adjustment

(调整) can be very difficult and lead to the new arrival rejecting the new culture. This"rejection stage" can

be quite dangerous because the visitor may develop unhealthy habits, such as smoking, drinking too much.

     The third stage is characterized by gaining some understanding of the new culture. A new feeling of

pleasure and sense of humor may be experienced. And you are becoming stronger by learning to take care

of yourself in the new place. Things are still difficult, but you are now a survivor! This is called the"adjustment

stage".

     The fourth stage can be called" at ease at last". Now you feel quite comfortable in your new environment.

You can deal with most problems. You may still have problems with the language, but you know you are

strong enough to deal with them. If you meet someone from your country who has just arrived, you can be

the expert on life in the new culture and help them to deal with their culture shock.

     The fifth stage is the stage that is called the"re-entry shock." This occurs when a return to the country

of origin is made. One may find that things are no longer the same. For example, some of the newly learned

customs are not in use in the old culture.
