听力原文： My first semester of college was the worst I've been through. I had made plans during the summer to share an apartment with two of my close friends from high school. But before we moved in, problems started developing.
One of the two girls I was to share an apartment with was going to work instead of going to college. However, a week before we were to move in, she found out that she didn't get the job. She was forced to live at home and look for work. The rest two of us lasted for a month and then agreed that we couldn't make it with the higher monthly rent payments. I started looking around.
I found another apartment and the rent wasn't bad. The place was noisy, but it was the best I could afford for the time. However, one clay when I returned, I saw smoke coming from the back of the house. The cottage had caught fire, and my room was a burned mess. I was once more out of a place to stay.
I finally gave up looking around and moved home. I had to drive forty miles to school every day, so I almost spent as much on gas as I would have on lodging. I was very bored. I almost lost the will to study. It had been really a bad semester!
