Last night I was getting ready for the coming examination                     76.         

when the noise from my neighbor interrupts me. The noise                 77.           

went on and on. It was too loud that I could hardly pay                         78.         

attention to my study any longer. So I went to my neighbor’s houses       79.         

and said to him:“Excuse me, would you please turn up the               80.          

TV?I’m preparing for tomorrow’s examination.”Hear these                81.         

words, his face turned red. But he said , “OK,I will.                       82.         

I’m very sorry have made so much noise. Just now, the football            83.         

game was very wonderful. I was too exciting to control                      84.          

myself. I won’t do that again. Good luck in the your coming                85.          

examination.” After that, I got down to my study.
