题目内容：

That cold January night, I was growing sick of my life in San Francisco．There I was, walking home at one in the morning after a tiring practice at the theater．With opening night only a week away, I was still learning my lines．I was having trouble with my part-time job at the bank and my acting at night at the same time．As I walked, I thought seriously about giving up both acting and San Francisco．City life had become too much for me．

As I walked down empty streets under tall buildings, I felt very small and cold．I began running, both to keep warm and to keep away any possible robbers．Very few people were still out except a few sad-looking homeless people under blankets.

About a block from my apartment, I heard a sound behind me．I turned quickly, half expecting to see someone with a knife or a gun．The street was empty．All I saw was a shining streetlight．Still, the noise had made me nervous, so I started to run faster．Not until I reached my apartment building and unlocked the door did I realize what the noise had been．It had been my wallet falling to the sidewalk.

Suddenly I wasn’t cold or tired anymore．I ran out of the door and back to where I’d heard the noise．Although I searched the sidewalk anxiously for fifteen minutes, my wallet was nowhere to be found.

Just as I was about to give up the search, I heard the garbage truck（垃圾车） pull up to the sidewalk next to me.When a voice called from the inside, “Alisa Camacho?” I thought I was dreaming．How could this man know my name? The door opened, and out jumped a small red-haired man with an amused look in his eyes．“Is this what you’re looking for?” he asked, holding up a small square shape.

It was nearly 3 a.m．by the time I got into bed．I wouldn’t get much sleep that night, but I had got my wallet back．I also had got back some enjoyment of city life．I realized that the city couldn’t be a bad place as long as people were willing to help each other.
