听力原文： As you probably know already, the Student Union Building is the main centre of social life here, as indeed it is in most British Universities. The Union runs a weekly program of events for all tastes.., oh everything from discos to talks by guest speakers. Many of these events are fund raising activities for charities, which the Union takes very seriously. They manage the Students Union paper shop, selling magazines and newspapers, as well as stationery, sweets and so on. Urn... Then ...,let me see.., there's the Ticket Shop, where you can get some very good deals on, well for example, coaches to London or inexpensive charter flights, as cheap as you'll get anywhere people say, or tickets for big pop groups playing here or at other venues all over the country, or plays in London--oh and we mustn't forget the Union Cafeteria and the Big New Diner. In addition, the Union runs their own advice service, offering help with financial matters such as grants. I am sure you realize anything medical should be discussed with the University Medical Service, which also has an excellent counseling centre. I think that was made clear yesterday. However, the Union has its own officer who can give advice on legal problems. Which activity of the Union is not mentioned by the speaker?
