Last Friday, the students in our school are organized to visit the exhibition on China’s development. We watched some outstanding achievement in China and a guide gave us unusual introduction to the exhibition. While visiting, they were excited and proud of that our nation had achieved. After visited the exhibition, we had a class meeting in the classroom. We worked in groups and delivered a short speech on turn, sharing our thoughts on what we have seen. Neither the exhibition or the class meeting is memorable. We will do nothing but to work hard and make contributions to our country.
