听力原文:It was 2:05 in the afternoon. When I entered the classroom, I was surprised to see a video camera. Our class teacher was operating the camera, and my classmates were all talking among themselves slowly. Most of us had never been in front of a video camera before, so we were quite nervous. As for of myself, I had once faced one at home, my uncle was shooting when we were celebrating my sister's birthday. But this was completely different. We had to talk about our articles as if we were reading news on TV. The funny thing was that every time I tried to face the camera and talk about my article, I forgot the article and couldn't resist looking down at it. It was a completely different experience for me, thanks to our class teacher. What were the students going to do?
A.
They were going to read their articles before a video camera.
B.
They were going to read news on TV.
C.
They were going to celebrate the writer's sister's birthday.
