When crops are green, locusts look green. But as the harvest time c\underline{3}, locusts change to the same brown colour as crops have.

On a cold January night, I was growing sick of my life in the city I lived. There I was walking home at one in the morning after a tiring practice at the theatre. I was having trouble dealing 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 the life in this awful place.
As I walked down the empty street under tall buildings, I felt very small and cold. “Run!” I told myself and began to do so, both to keep warm and keep away from any possible danger.
When I was about a block from my flat, I heard a noise behind me. I turned quickly, but the street was empty. The noise had made me nervous, so I started to run faster. I didn’t realize what the noise had been until I reached my flat. It had been my wallet falling to the street.
I wasn't cold or tired any more. I ran back to where I had heard the noise. Although I searched the street for fifteen minutes, my wallet was nowhere to be found.
Just as I was about to give up the search, I heard a rubbish truck stop next to me. A voice called from the truck driver, “Alisa Camacho?” I thought I was dreaming. How could this man know my name? The door opened and a man jumped out. “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 didn’t get much sleep that night. But I had got my wallet back. I also had got back some enjoyment of city life.
