阅读理解。

     I have a love-hate feeling with 8 o'clock classes. I like to get started that early, but most students don't.

They usually came in late and looked sleepy at that hour.

     One day I was really angry at it. I was excited about the history lesson, but no one else seemed to be. I

wrote things on the blackboard. I moved around the room. I told stories. I tried humor (幽默). It was useless.

Their looks didn't seem to change. I was frustrated.

     I forgot to keep time. I was going to talk more when I looked down at my watch. It was already two

minutes past the end of class. So I just ended suddenly and soon the students began to pick up their book

bags and rushed out the door on their way to another class.

     While I was watching them leaving, I put away my own books, notes and papers. I took them up and

stepped out into the hall. I was tired and a bit sad. I had put everything I knew into that class and it had not

seemed to work. Then, as I started across the hall to my nearby office, a student came out the back door

of the classroom and caught up with me.

     Randy sat at the back of the classroom. I thought he wanted to ask why I didn't correct their exam

papers or maybe he wanted to ask for leave or… It was none of that. With his eyes sparkling (闪烁), Randy

said,"This is the first time I've not wanted a college class to end."

     The tiredness lifted. I had done better than I thought. I don't know if Randy will ever understand how

much he did for me that day.
