任务型阅读 March 24th This morning, we had a school trip to the Dashan Collection House, a building of two floors. It is open from 9:00 am to 5:00 pm. We took the school bus and arrived at 9:00. When we entered the collection house, our eyes were caught by a collection of old photos of the town on the walls of the front hall. Those photos told us something about the history of the town. And then in the Art Room, we saw many pictures of the countryside. The colors of the flowers and trees are rich and bright. All at once, I lost myself in the beauty of nature. Then we went upstairs. On the left, there were over one hundred different clocks. The oldest clock was already more than two hundred years old. To my surprise, the clocks all worked well and they could tell the right time. It was then ten o'clock, and some clocks produced different beautiful sounds. It seemed to be a concert. How amazing! On the right there was also a stone collection. The stones were from all over the country. They were in different sizes, colors and shapes. Some looked like different kinds of animals. I really liked one stone that looked like a little monkey. It looked very nice. The collections there were wonderful. So they stayed there until 11:30 in the morning. I had a great time and really liked the school trip. 1.
