用英文翻译：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列举出了也门的饥饿问题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 have chosen is the hunger problem in Yemen. Although we have introduced Yemen's geography, environment, causes of poverty, food and aid organizations to illustrate the hunger problem in Yemen, we did not focus on the causes that led to these problems, such as the civil war and economic imbalance, as mentioned in the second part of the PPT. Therefore, the lack of a prominent theme made our PPT very long. Through our presentation, we also realized that our presentation skills were not experienced enough, such as lack of body language and not fully utilizing the presentation space. This pre-experience has made us aware of our shortcomings and motivated us to continuously improve.
