In the Examination Hall-考场上

In the.Examination Hall
     When I was walking along the passage, I saw many students waiting outside the examination hall. I got the doors open, and they entered the hall one by one. I knew that they were excited from their whispering mouths. Obviously, they were trying to recall what they had memorized.
      The examination hall was clean and orderly. All the desks and chairs were arranged six by seven in straight lines. The atmosphere showed that an important event would soon happen, and it seemed that the students' future would be decided at this very moment.
      There was Li, sitting in the middle of the third row, a diligent boy who would like to ask questions. He now looked tired and nervous, and his eyes were surrounded by two big black circles. I could make out that he must have spent the whole night preparing himself for today's examination.
       In an instant, the bell broke the silence.  Li became extremely excited, his lips and hands trembling hysterically,his feet moving involuntarily.
       The examination papers were distributed to the students.They quickly glanced at the questions and started working immediately. Some heaved a heavy sigh of relief, some wore a smile on their lips, while some others scratched their heads savagely. A smile flickered through Li' s face, but he lost no
time to start working.
     Soon, the hall was drowned in the noise of seratching paper and regular breathing.
     The bell rang again and all papers were handed in.All the students Streamed out of the hail, busily exchanging their opinions and results.  Among them was Li, who,though wearing a somewhat trlumpharit smile, looked extremely exhausted as if he had gone through a battle.
