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”. 小题1: _____. We are thrilled to be in the new environment, seeing new sights, hearing new sounds and language, eating new kinds of food. 小题2:____.

小题3:______. 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”. 小题4:_____. 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. 小题5:_____. You may still have problems with the language, but you know you are strong enough to deal with them.
