用英语翻译：我们选择的主题是也门的饥饿问题虽然我们通过介绍也门的地理位置环境造成贫穷的原因吃的食物和帮助的组织向大家描述了也门的状况但是我们没有在这些问题中着重讲述造成这些问题的原因就如在PPT的第二部分中造成也门贫穷的原因有内战经济失衡等我们可以着重讲述内战是如何造成也门贫穷的原因。正因如此没有突出的主题让我们的PPT变得很长。通过演讲我们也意识到我们演讲的经验不够丰富例如肢体语言不够丰富没有利

The theme we chose is the issue of hunger in Yemen. Although we introduced Yemen's geography, environment, causes of poverty, food, and aid organizations to describe the situation in Yemen, we did not focus on the causes of these problems, such as in the second part of the PPT, where the causes of poverty in Yemen include civil war, economic imbalance, etc. Therefore, we can focus on how the civil war has caused poverty in Yemen. As a result, there is no prominent theme, making our PPT very long. Through our presentation, we also realized that our presentation experience is not rich enough, such as inadequate body language and not making good use of the presentation space. Through this pre, we deeply understand our shortcomings, which motivates us to constantly improve.
