What do the students have to do if they want to join a special interest class?

I’m going to tell you now about the special interest classes that we have on Wednesdays. You can choose what you like to do. We put up a list in the notice board and you must sign your name under the class you have chosen. Then, at 1:45 on Wednesdays, you go to the room where that class is.
    Now, I’ll tell you which class is in which room. The teachers will be in their usual classrooms. So Mike will be in Room 7, Nicky will be in Room 4 and Paul will be in Room 2. Except for Philip, who’ll be in the language laboratory, and Alison, who’ll be in the library. I’ll explain why in a minute. OK. So what are the classes? Well, there are two sorts, really. Some of them are to give you extra language practice if you want it, and some of them are more general. But all the classes will be good for your English. For example, Philip will be giving you an opportunity to improve your understanding of spoken English. You can go to the language laboratory and he will help you to choose a listening exercise which will suit your particular needs. Alison will be showing slides in the library every week to give you some idea about what you can see if you visit other parts of the United Kingdom. They’re very good slides and Alison will be able to tell you lots of interesting background information. The first week she’ll be talking about Edinburgh. Mike will be doing English through Songs. That’s a chance to improve your English and get to know the words of some recently successful pop songs in detail—find out what they really mean! Perhaps even learn to sing them! Nicky is going to do poetry. This will be especially useful for those of you who are taking the literature exam, although anyone is welcome to join, as she will be looking at all sorts of different work.
