As soon as the summer vacation was over, we went to Ningbo to play. We played rafting, which was very interesting. Bang, floating away from top to bottom, so cold all over! We went to the water park again, where there were all kinds of water slides. I really had a good time! After relaxing, I began to do my summer homework every day. Finish the dance class, Cambridge English and swimming class that my mother signed me up for. Finally, I finished all my summer homework in late August, and my mother rewarded me with another trip. In this way, we went to Zhoushan Islands, where the scenery was very beautiful, the grass was lush, the flowers were delicate and the air was fresh ... We went to Shengsi Islands by boat, and on the boat, I realized for the first time what the sea and the sky were the same. It's beautiful. We lived happily there for a day. Then we went to Gouqi Island by boat and arrived at Gouqi Island. We picked up a lot of shells, which are very beautiful. We went to Peach Blossom Island happily again. Huang Shuwen and I built a chocolate castle on the beach of Peach Blossom Island. Very interesting! This trip has brought me great gains. Let me understand a lot of truth. I also learned a lot of knowledge. This is the end of my summer vacation. I have adjusted my mind. In this new semester, I will study harder.
