听力原文： I wasn't too fond of the lecture classes of 400 students that were in my general courses. Halfway through my second term, when I was considering whether or not to come back in the fall, I went on the Internet and came across AmeriCorps. Then I joined the organization. And that was what I did last school year. I worked on making roads, building a house and serving as a teacher's assistant. It's been a great experience. And I've almost learned more than what I could have in college. Since I didn't really want to ha at that school and I wasn't interested in my major anyway, I think this was better for me. After 1,700 hours of service, I received 4,750 dollars. I can use that to pay off the money I harrowed from the banks or for what I need when I go hack to school this fall at Columbus State in Ohio. Classes are smaller there, and I'll be majoring in German education. After working with the kids, now I know I want to be a teacher. Why did the man decide to leave the college in his second term?
