     In the past, people used to travel to foreign countries because they thought they would be different
in many ways-the buildings, the food , the national dresses and so on. At present, however, one large
city is similar to another. They all have their Hilton or Sheraton Hotels every-where. They all have their
McDonald's, their KFCs and their Pizza Huts. Office buildings look the same everywhere, and most
city centers are full of office buildings. And of course, people are driving the same brands (品牌) of
Japanese or European cars.      
     Then what is the foreign travel for? What do tourists hope to experience in a foreign country that
they cannot experience at home? The answer could be that people are very interested in the past. It is
a nation's history and culture that are the main attractions. Most people travel over- seas to find out
what foreign history and culture used to be like, not what they are like today. Tourists try to learn the
history and culture of foreign countries by visiting different kinds of museums.      
     Every country also has its own beautiful places for tourists to visit. Their own special  scenery
(风景) would certainly attract tourists from other countries.      
   Finally, there is perhaps a country's attraction: its people. A country is not just its old buildings , its
works of art(艺术品) or beautiful places, it’s also the people who live in it. This is why a country such
as Thailand attracts  millions of people. The tourists come mainly because of the friendliness(友好) of
the people there. It is why the Pacific islands are also so popular. The friendly, smiling people make
visitors feel welcome.
