We may know that there are four basic periods for human beings to pass through when you enter and live in another country. This process(变化过程) helps you deal with culture shock(文化冲击).

Culture shock begins with the "honeymoon period". This is the time when you first arrive in a place where everything about the new cu1ture is strange and exciting. You see new things, hear new sounds and language, eat new kinds of food. This period can last for quite a long time because you feel very happy.

Unluckily, the second period can be more difficu1t.  After you have got used to your new life, you can become very tired and begin to miss your motherland, your family, your friends, your pets and so on. Al1 the little prob1ems in life seem to be much bigger and more worrying when you face them in a foreign country. This period can be very difficult and lead to moving backwards quickly.

The third period is called the "adjustment(调整) period". This is When you begin to realize that things are not so bad in the new country. Your sense of humor usually becomes stronger and you realize you are becoming stronger by 1earning to take care of yourself in the new place. Things are still difficult, but you are now a survivor(善于求生者).

The fourth period can be cal1ed "at ease at last". Now you feel quite comfortable in your new place. You can deal with most problems that you have. You may still have prob1ems with language,but you know you are strong enough to deal with them. At this time, you may feel a little uncomfortable if you go back to your motherland.
