One cold night, I was growing sick of my life in San Francisco．There I was walking home around one o’clock in the morning after a   31  practice at the theatre. With the opening night only a week away, I was still learning my lines by heart. I was having   32 handling my part-time job at the bank in the daytime and my acting at night at the same time. As I walked, I thought seriously about 33 both acting and San Francisco. I had 34 too much of city life.
As I walked down the 35 streets under the tall buildings, I felt very small and cold, so I began 36 both to keep warm and to keep away from any possible robbers. Very few people were still out 37 a few homeless people under blankets.
About a block from my 38 , I heard a sound behind me. I   39  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 40 so I started to run faster. Not until I reached my apartment building and unlocked the door did I   41 what the noise had been. It had been my wallet 42 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   43 for 15 minutes, my wallet was   44 to be found.
Just as I was about to quit the 45 , I heard the garbage truck stop to the sidewalk next to 46 . When a voice came 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 blonde(金发碧眼的) man with an 47 look in his eyes. “Is this 48 you’re looking for?” He asked, holding up something like a wallet.
It was already 3 a.m. by the time I got into bed. I couldn’t get much sleep, but I had got my wallet back. I also had got back some 49 of city life. I realized the city couldn’t be a bad place 50 people were willing to help each other.

A．comfortable

D．delightedly
