第二部分阅读理解（共两节，满分40分）
第一节(共15小题；每小题2分，满分30分)
Coca Cola is an American icon – and sometimes seen as a symbol of the country’s economic right. But one of the world’s famous companies will play a different role during the 2008 Olympic Games: promoting Oriental (东方的) culture to the world.
The man who is in charge of the project couldn’t be more suited for the job. The American has lived in the country for about 15 years, speaks fluent Chinese, and considers Beijing his hometown. David Brooks, vice-president and general manager of the Olympics Project Group of Coca Cola China, who has lived in the country for more than a decade, said: "We are working very hard to create a lot of special different kinds of items that are very Oriental in character and have a strong Oriental identity. "There is a lot of curiosity around the world about the country and about Oriental culture. So, we think we also have a role and opportunity to show people so many things."
Coca Cola has launched its logo(标识) with the Beijing Games, featuring kites and lucky clouds, traditional elements in the Oriental culture. Brooks considers it a good start. "We are doing a lot of similar programs, and in the next 570 days or so, as we count down to the Games, you will see more examples with strong Oriental spirit and identity."
He certainly has a sense of history. "The Olympic spirit, which is an ancient spirit from over 2,000 years ago, is alive. It still lives through the Olympic Games in the idea of balancing the body and mind, and doing the best," said Brooks, who has been to three Games. "It's like a big family celebrating together. I think all the members of my team and I feel it is a special honor to be involved in the Games."
