XUE Bai, a 21-year-old university student, hopes to volunteer for Beijing's 2008 Olympics. "I want to do something for the Olympics. It is also a kind of learning for me," said the fourth-year student at Beijing Foreign Studies University. Now it is time for Xue to act on her plan. The Beijing Organizing Committee for the Games of the 2008 Olympiad  will start to recruit volunteers on August 28. The Olympics will need around 70,000 volunteers and the Paralympic Games  will need another 30,000. University students like Xue will make up the majority of the volunteers. But the Olympics also need other volunteers - ordinary citizens and foreigners, for example. Students in Beijing should apply through their universities. Other volunteers may apply online or submit a written application. The online application system and a hotline will be open next Monday. For applicants outside Beijing, the application process begins in December. There is plenty of work for volunteers to do. For example, there will be chances to help publicize the games over the next two years. During the games themselves, volunteers will clean, serve food, marshal or offer language help. The Sydney Olympics in 2000 was the first that placed special emphasis on the role of volunteers. It used more than 45,000 volunteers in different roles. In the 2004 Athens Olympics, around 45,000 volunteers were used. More than 70,000 volunteers will be needed for the Olympic games and Paralympic Games in 2012, the London Olympic Organizing Committee has said. The passage mainly tells us  _  .
