Note
thunderstorm 雷を伴ったあらし;
———————————-
I was asleep at 3 a.m. Suddenly, there was a loud noise, and my apartment building shook. I thought it was an earthquake at first. Then I realized that it was a thunderstorm. The thunder went on for another 15 minutes. Each time I saw a flash of lightning, I started to count. If you count to 3, the lightning is about one kilometer away. I counted to 10. That means that the lightning was about 3 kilometers away. Sometimes I saw a flash and heard the thunder right away. The lightning was just above me! Finally, the thunder stopped, and it started to rain heavily. I went back to sleep. (by Prof. Douglas Jarrell)
