题目是：旅游到一个别的国家，游客是否必须入乡随俗，同时放弃自己的文化？
这样的题目，分析是关键。自己的习俗和异国文化习俗是否必然矛盾冲突呢？这是突破点。根据这个进行分类，进行二分法阐述。如果文化冲突比较显著，就最好入乡随俗，否则可以保持自己的习俗。课堂提问，什么是文化？预料之中，几乎没有人能够回答出来。因为这些学生回答问题不是通过大脑思考，而是想在自己大脑储存——他们虽然没有任何储存——中搜寻记忆的答案。这是中国学生最显著的特征。多年教室的蹂躏，早已使得他们完全丧失思考以及说人话的能力。
What is a culture? Although there is no an agreement about the definition of culture, people generally consider it to be the ways people eat, play, dress, drink, think, and work. When one person travels in a foreign country, the foreign culture is not necessarily completely incompatible with his or her native ways. Therefore, it is not always true to do in Rome as a Roman Does.
If one travels in a public culture, that is, where the social order, economic and other relationships between people are maintained by laws rather than by custom or kinship, it is safe for the traveler to do things in his or her own ways，because the public culture welcomes different or even conflict opinions, people, and ways. Take New York, the big pot, as a typical case in point. In this city everybody has an angle and everyone has the right to do whatever delights him or her in cast that it is not illegal.
If one travels in a folk culture, however, it is better to do in Rome as Romans do. A folk culture is a culture featured by clans, kinships, and customs. In a folk culture different ways of doing things are less welcomed. In such a culture, if one remains his or her own ways of doing things, hardly can he or she be able to enjoy the journey. Worse, the traveler might be in the deep troubled water.
Therefore, whether one must follow the new ways of doing things and whether one must keep the native culture depend on a variety of specific conditions.
