    Psychologists tell us that there are four basic stages that human beings pass through when they enter and live in a new culture. This process, which helps us to deal with culture shock, is the way our brain and our

personality react to the strange new things we encounter when we move from one culture to another.

    Culture begins with the "honeymoon stage". This is the period of time when we first arrive in which

everything about the new culture is strange and exciting. We may be suffering from "jet lag" but we are

thrilled to be in the new environment, seeing new sights, hearing new sounds and language, eating new kind

s of food. This stage can last for quite a long time because we feel we are involved in some kind of great a

dventure.

    Unfortunately, the second stage can be more difficult. After we have settled down into our new life, we can become very tired and begin to miss our homeland and our family, friends, pets. All the little problems

in life seem to be much bigger and more disturbing when you face them in a foreign culture. This period of cultural adjustment can be very difficult and lead to the new arrival rejecting or pulling away from the new

culture.

    The third stage is called the "adjustment stage". This is when you begin to realize that things are not so

bad in the host culture. Your sense of humour usually becomes stronger and you realize that 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!

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

You can cope with most problems that occur. You may still have problems with the language, but you

know you are strong enough to deal with them.

     There is a fifth stage of culture shock which many people don't know about. This is called "reverse (颠倒、交换)culture shock". Surprisingly, this occurs when you go back to your native culture and find that

you have changed and that things there have changed while you have been away. Now you feel a little

uncomfortable back home. Life is a struggle!
