This week was full of surprises. On Monday, I helped my friend solve a difficult math problem, and he was very grateful. On Wednesday, our class went on a field trip to the museum, where we learned about ancient history. On Friday, I joined a volunteer activity in the community park, planting trees and picking up litter. These experiences made me feel happy and fulfilled.
这一周充满了惊喜。星期一，我帮助我的朋友解决了个棘手的数学问题，他非常感激。星期三，我们班去博物馆郊游，学到了很多关于古代历史的知识。星期五，我参加了社区公园的志愿者活动，种树并清理垃圾。这些经历让我感到开心且充实。
