We were sitting in the classroom quietly, waiting for the invigilator. We were anxious to get the examination paper and see whether it was easy or difficult.

　　The invigilator came into the classroom. He first looked around. Then he counted the papers. We could only hear the papers"fricative. I had a look at my watch. We would be examined in eight minutes. I felt a bit nervous. I thought to myself,Will the exam be easy or difficult? Will the last question be very hard for me to work out?The invigilator began to deliver us the papers. I had been ready. As soon as I got the paper, I began to write quickly. At this, the invigilator said loudly,You can"t write until the bell rings.I felt sorry for that. I watched the hands of the clock and thought hard. I counted quietly,four minutes, three minutes, two minutes,thirty seconds, twenty-five secondsDing The bell rang. We picked up our pens and began to write quietly.

　　What a long time we had been waiting!
