A、Course polices. B、Class participation. C、Writing projects. D、Course assignments. AWhat is the main topic of this talk?

First of all, I would like to explain the course polices to you. The class meets three times a week for twelve weeks. In addition to the weekly written assignments, there are reading materials which must be covered before the end of the term. The written projects must be handed in on certain days of the week, but you are free to complete your readings at any time during the week when they are assigned.
    Attendance in this class is taken at roll time. If you miss more than five class sessions, I will submit a written absence report to your adviser. If you must miss a class because you are ill or have an urgent matter to attend to, you need to inform me in order to avoid an unexcused absence. It is your responsibility to make up the work if you miss classes for any reason whatsoever. If you hand in your assignment after the due date, your grade will be lowered.
