     The Beijing Olympic Games will have 21,880 torchbearers (火炬手) for the torch relay (火炬接力). It

is the biggest in the Games' history. Here let's know about some torchbearers.

     ◆ Luis Hone, 14, is from Colombia. He lives in Zhuhai, Guangdong Province. He moved to China with

his parents as a baby. "I can speak English, Chinese and Spanish. I love China, which has been my world

all my life," he said. "The torch relay is a good chance to improve the understanding between people of the

world." 

    ◆ Sang Lan, 26, will complete the torch relay using her wheelchair. Sang's fingers are not agile (灵活的)

because of her injury (受伤). The IOC officials suggested adding framework (框架) to her wheelchair to

hold the torch. But she insists that she will hold the torch with her hands. "I believe if you put your heart

into something, you can solve any problem," she said. 

     ◆ Liu Xuan, 17, is from Nanjing Foreign Language School. He is an energetic student. He enjoys various

sports including football, basketball, badminton and running. "It will be an honor to be a torchbearer," he said. 

     ◆ Zhang Jie, 23, is a reporter with Guangzhou Daily. "Torch relay is a good way to let the world know

China better," Zhang said. "Tin very proud that I can be part of it."
