　　Good morning, ladies and gentleman, welcome to Beijing. To begin with, I would like to introduce myself: I am the tourist guide from China Travel Service and it’s great honor to stay here with all of you for a whole day. Just as the old saying goes, “It is always a pleasure to greet a friend from afar”， I wish all of you to enjoy yourselves during this trip.
　　The following is schedule of the day. The first spot we are going to visit is the Great Wall, the grandest fortification in ancient China. The next sight to look around is the Ming Tombs, which is one of the best-preserved tombs for 13 emperors in Ming Dynasty more than one thousand years ago. In the afternoon, we will go for the Summer Palace, the royal park for Chinese ancient emperors.
　　Currently we are on the way to the Great Wall. Dating back to the seven century B.C., the Great Wall is constructed by respective states for fortifying against invasion of neighboring states. By the reasons of long history and its length, it becomes one of the eight wonders in the world and represents the highest wisdom and crafts. From the top of the Great Wall, we can enjoy a magnificent view of continuous mountains, green trees and blooming wild flowers. It is no doubt that one says, “He who has never been to the Great Wall is not a true man”。
　　Above is my introduction to the Great Wall. If any of you have questions, please feel free to ask me at any time.
