     Last Monday, we were having our Chinese class while the teacher suddenly slipped and fell.
We were both worried about her. One of the boys carry her on the back, with the help of some
others, to the clinic immediately. It turned out her right leg were broken and she had to stay in
the hospital. The followed day, we went to visit her with flowers and fruit. Seeing her lying in the
bed with her leg wrapped in bandages, we felt sorry to her and hoped that she will recover soon.
This Thursday she returned to the class on a wheelchair to give us lessons. We were all deep
moved and proud of having such a responsible teacher.
