Paragraph B   When I studied abroad in Japan, I chose a homestay rather than a dorm. It was a good idea. I spoke Japanese to my host family, so my Japanese got better fast. My classmates lived in a dorm and they spoke English all the time. My Japanese was much better than theirs after several months. Today, I still keep in touch with my host family. I learned so much about life in Japan from them.
