阅读下面短文并回答问题,然后将答案写到题后的横线上(请注意问题后的词数要求)。

[1]Moving abroad is an exciting experience. The first breath of fresh foreign air as you step down from the plane or train is the kind of sensory(感官的) memory that stays with you forever, as is the process of starting to set up a new life in a new place with new faces and new friends.

[2]Yet many people will experience a sense of what is commonly called“culture shock” when moving to a new country. Some give the definition of culture shock as a sense of “trauma(创伤)”experienced by an individual when moving to a new country. Others comment that it can be produced by some more subtle changes. In the case of moving to a new country, it seems obvious that culture shock is a common phenomenon.

[3]You may not ______________________, creating the frustration of not being able to communicate. This in turn can create a sense of isolation from those around you and an unwillingness to try to integrate(融入群体). Difficulty in communicating often makes easy daily tasks seem like monumental battles.

[4] In a new country, you may also have little or no knowledge of local customs. These customs are often undervalued when we think about culture shock, but they can often strengthen a sense of “otherness” for an individual in a new country, especially in cases where social customs are more like unwritten rules of society.

[5] So what can be done to overcome culture shock? For many, it is a question of time. Time allows people who move to a new country to get used to their new surroundings, as well as a new language and a new set of social customs. Yet for many, it is also a question of confidence. Immersing(使沉浸在)yourself in a new cultural environment is terrifying at first. But the more you push yourself to interact with others, the quicker you will start to understand and appreciate the differences between two cultures.
