I was caught in the war and put to prison.I was sure that I was to be killed,I became  terribly nervous.I reached in my pockets to see if there were any cigarettes(香烟),which had   36__ their search.I found one and because of my  37  hands,I could only get it to my lips.But I had no  38 .

I looked   39  the bars(铁栏)at my jailer(狱警).He did not make eye contact with me.I called out to him,“Have you got a light?” He looked at me,and came over to  40  my cigarette.

As he came close and lit the match,his eyes met with mine.At that moment,I smiled I don't know  41  I did that,Perhaps it was  42 ,perhaps it was because,when you get very close,one to another,it is very hard not to  43 .In any case,I smiled.It was   44   a spark(火花)jumped across the distance between our two hearts.I know he didn't want to,but my smile jumped through the bars and caused a smile on his lips.He lit my cigarette but stayed near,looking at me  45_ in the eyes and continuing to smile.

I kept smiling at him,now   46  of him as a person and not just a jailer.And his looking at me seemed to have a new   47 ,too.“Do you have kids?” he asked.

“Yes,here,here.”I took out my wallet and nervously searched for the pictures of my family.He, too,took out the pictures of his family and began to talk about his  48  and hopes for them.My eyes were filled with   49 .I said that I feared that I'd never see my family again,never have the chance to see them grow up.Tears came to his eyes,too.

Suddenly, 50  ,he unlocked my cell(牢房)and silently led me out.Out of the prison,quietly and by   51  routes,out of the town.There,at the edge of town,he set me   52 .And without another word,he turned back toward the town.

My life was  53  by a smile.

Yes, the smile—the unaffected,unplanned,natural connection between people.I really believe that if that part of you and that part of me could   54  each other,we wouldn’t be enemies.We couldn’t have  55 or envy or fear.
