blackboard, the class burst out 9  . They laughed and laughed. They laughed so much, in fact, that I
was  10  the headmaster would come and see all this.
     I asked the class to  11  ,but the more I talked, the more they laughed.  12  I thought I had better
pay   13  attention to them and 14 to write on the blackboard. As I did this, they laughed even harder.

When he came in, he started laughing, too.
    "Good Heavens! "I said," Will  17  please tell me what is so  18  ?"
