It’s a sad and familiar voice that we often hear in big cities: “Can you spare some change?”
Usually, when faced with that particular     , I have feelings of guilt if I pass by      giving a coin or two.
I had that feeling    in Venice while on a tour of Italy’s famous sites in 2006. I had taken refuge from the      in a quiet café. Outside, there was an old woman kneeling on the hard, ancient paving stones,     .
Steady      of tourists were walking past her. A young backpacker stood away from the crowd,    drinking in the vistas（景观、景色）, but I noticed the young traveler was also      the old woman.
A tourist group walked along the street,      the woman and walked on.      group of tourists arrived and walked past the old lady. The backpacker watched      everybody else went on their way, focused on the      around them. Then, I was preparing to leave when I caught sight of the backpacker stepping forward and      some money in the woman’s cup. He did this somewhat     just before the arrival of another tourist group. As I     , the leader of the group stopped and put some money in the cup. Having been shown the way, other tourists followed suit and      some more coins to the cup.
His work done, the young man walked over to the old beggar-woman, patted her on the shoulder and said, “I hope that      a little.”
I don’t know if the woman understood his English or      what had just happened, but I did.
I placed some money in the woman’s cup and continued my travels,      after witnessing such a      act of kindness.
