Mr . : Please open your books to page 10 . ( To Mary ) Can I help you ?   I'm sorry that I'm late . I couldn't find the room .   Mr . : That's alright . It's the first day of school , after all .   What are we doing ?   Mr . : I'm asking the class to read page 10 to themselves . Then I'm going to ask some questions about the passage .   May I have a book ?   Mr . : Here . Write your name inside the front cover . Remember that you must return the textbook to me at the end of the semester , so keep it in good condition .
