听力原文： Now, my name is Pat Baker, I work for student services and I'm going to tell you all about our mentoring scheme for new students. What happens is this: each of you, if you want to, will be assigned a mentor—that is, someone who's been studying here for a year or two and who can show you how things work, give you advice and just generally be a friendly contact for you in the university. What the mentor does is have a group of usually two or three students and he or she organizes meetings about once every two weeks—where you chat about your problems and your mentor will give you the benefit of his or her experience. Mentors will be able to tell you about academic systems, which are so different at university from what you were used to at school. Also, because at university you are much more independent, they can suggest techniques for studying which will help you to keep up-to-date with your work. This university is an enormous place, so another thing which they'll be able to help with is university facilities—you know, anything from sports halls to libraries to medical services and they can probably help you get involved in all sorts of social activities too, you know, parties, clubs and sports. Your mentor will be able to show you how to get an e-mail account… they don't cost anything to students. For people who have never been away from home before, a mentor is a useful contact and support—somewhere between a friend and a parent. 15.According to the talk, who are mentors? 16.How often does the mentor organize meetings? 17.With regard to what mentors can help, which one is NOT mentioned? 18.Which of the following is NOT mentioned as university facilities?
