我近期参加了一项志愿服务活动。活动期间，我聆听了专家的讲座，并进行了PPT演讲。我收获很多，但也发现了自身的一些不足。
首先，我从专家那里学到许多实用的技能，懂得了怎样帮助外国游客，以及怎样更好地和他们沟通。这段经历让我得到成长。
但是我的PPT演讲还有不少问题。主要有三点：我说话语速偏快，部分听众难以跟上；演讲时容易紧张，偶尔停顿，表达不够流畅。除此之外，演讲中缺少足够真实事例，内容不够生动。
为了提升自己，我制定了一些计划。我会多多练习英语口语，放慢语速，保证表达清晰。我会反复练习演讲，增强自信心。我还会搜集更多真实故事，让演讲更加出彩。
这次志愿服务给了我宝贵的启示：优质的志愿服务不仅需要热心，也需要良好的表达能力。我会改正自身问题，持续进步，相信下次我能表现得更加出色。
Reflection on Volunteer Service
I joined a volunteer service activity recently. During the activity, I listened to experts’ talks and gave a PPT speech. I learned a lot, but I also found some of my shortcomings.
First, I learned many useful skills from the experts. I knew how to help foreign visitors and how to talk with them better. This experience helped me grow.
However, my PPT speech was not perfect. I had three main problems. I spoke a little fast, so some listeners could not follow me. I also felt nervous when I spoke. Sometimes I stopped and did not speak smoothly. Besides, I did not add enough real examples in my speech, so my talk was not lively enough.
To improve myself, I have some plans. I will practice my spoken English more. I will speak slowly and clearly. I will practice my speech many times to be more confident. I will also collect more real stories to make my speech better.
This volunteer activity teaches me a good lesson. Good service needs not only kindness but also good speaking skills. I will correct my mistakes and keep improving. I believe I will do better next time.
