The day our class went to new territories having a field trip. We were very excited but our geography teacher had not come with us. However, Mr. Cheng's friend who we did not know him joined us. After the trip, I was still did not know his name. I had a little bit unhappy because Mr. Cheng did not come. I was so glad that I can see waterfall, oxbow lake, plunge pool and pot-holes. Although the trip had many difficulties, but I think it is treasure to see the real features of the river. If I had not go to the trip, I would lose a treasure chance. In addition, our classmates helped each other to cross the river. I think it is a good atmosphere in a class. However I was still did not know map reading. It is very difficult but I will try to solve it.
