Good morning everyone. Welcome to English 101. Here's a copy of the pronunciation in my class, I will take daily roll and you will be allowed three absences without affecting your grade. If you miss more than three classes, you'll be expected to meet with me privately to discuss your standing in this class. I hope this is clear. The reason that I'm so strict in this class is because I want you to learn as much as possible during this semester. Also, we will have two exams and one final paper. I would suggest that you look over the pronunciation thoroughly and let me know if you have any questions. Your first assignment will be in your textbook. Please read and complete the exercises in the first three chapters. That's pages 2 through 60. I'll be more than happy to speak with any of you after class. That's all for today. See you tomorrow.
