LAST week, I went to the classroom after a simple yet satisfying dinner. It was about 5:30 pm, and the sun was setting. I was just walking in the hallway with my head lowered. Suddenly, I felt flashes (闪光) of reflected (反射) lights, so warm and bright. As I raised my head, I saw something that made me a little dizzy (眩晕的) – the sunlight. It came through the windows down the hall and poured over the floor. And it was its reflection on the flat floor that turned the whole place shiny and glorious (壮观的).
