WEARING a tie and smart suit, you are not yourself, a student any more, but a diplomat (外交官) at the United Nations (UN). You discuss global issues such as \"restarting peace talks in Palestine\" in English with other \"UN members\". This is what impressed a group of high school students who took part in an event to mark UN day. On October 24, 20 teenagers from Beijing No 4 High School and three other high schools in Beijing attended the fourth Peking University Model UN (模拟联合国). The event has been organized every year since 2000 by the university\'s Model UN Association (协会) for college students throughout the country. This year\'s conference had three sections: General Assembly (联合国大会), Security Council (安理会) and Youth Assembly, and it was the first time that high school students were invited.
