【正确答案】 B

【答案解析】[解析] 6-10 Why do people travel to distant lands? Many centuries ago, the reasons for travel were primarily economic or political. The idea of traveling for personal enrichment is fairly modern, only a few centuries old, and traveling just for adventure is even newer. Humans have always traveled across the earth. Early hunting-gathering people migrated in search of resources to sustain themselves. Later, after the spread of civilization, traders journeyed throughout Europe, North Africa, and the Middle East in search of perfumes, spices and other goods. Vikings traveled across the seas in search of fish, timber, and other natural resources. Europeans explored Africa and the Americas, conquering other civilizations and establishing colonies. These activities--the search for resources, the growth of trade, conquest and colonization--all stimulated the growth of tourism. While the earliest tourists traveled in search of resources, later tourists took trips for cultural, educational, and scientific purposes. During the seventeenth century, the young members of Europe's wealthy classes took "grand tours" through Europe to learn about languages, theater, music, and art. Beginning in the nineteenth century, naturalists like Charles Darwin studied animal and plant species in exotic places. Darwin's travels created interest in traveling for scientific advancement. In the early twentieth century, John Muir began to write about his wanderings through the southern United States, Alaska, and India, and his writings inspired people to preserve the natural world. Other travel heroes, such as Ernest Hemingway, wrote of their African safaris to hunt big game, and this exposed people to the possibilities of journeying to faraway places for adventure. The tourists of today take trips purely for pleasure, recreation, adventure, and, of course, personal growth. Many travelers now seek out the most distant places and the most unusual cultures. We can see this in ethnic tourism, a contemporary version of cultural tourism that includes visits to traditional villages and people's homes to observe social customs, see native arts and crafts, and watch local ceremonies, and so on. Ethnic tourism helps preserve aboriginal cultures that might otherwise be endangered by assimilation into the larger society. In fact, ethnic tourism allows us to enjoy folk dances and songs and ceremonies that might otherwise be lost. Another growing area of tourism is environmental tourism, which is related to ethnic tourism. Environmental tourists travel to pristine wilderness areas where few people have gone before. Their goal is to observe and learn about nature. The African safaris of today are environmental tourism. Their purpose is to observe and photograph wildlife rather than kill it. 6.
