Im Li Hua from China. Its my great honor to be here to say something about the global water shortage and ways of dealing with it. As we know, the global water shortage is becoming increasingly severe mainly due to global warming, environmental pollution and the ever-increasing population. Therefore, its high time we did something about it. Firstly, an effective way, I think, is to reserve water in a scientific way for future use. Secondly, new methods need to be developed to use the existing water resources, for example, turning sea water into fresh water. Thirdly, we must stop water pollution by law. Last but not least, its everyones responsibility to make good use of water, such as recycling and saving water in our daily life. In conclusion, people around the world should be aware of the real situation of water shortage, protect the present water resources and explore potential ones scientifically. Thats all. Thank you. 【亮点展示】 本文第二段简单介绍水资源短缺的现状后提出倡议；第三段具体陈述了解决问题的措施；最后一段总结发言。文章结构清晰，内容详略得当，重点突出。 语言上连贯而流畅，as we know，due to，分词结构turning sea water into... such as，常用句式its everyones responsibility...等的使用使文章词汇、句型丰富；firstly, secondly, thirdly, last but not least, besides等连接词的使用增强了文章的层次感，文意连贯。 【写作模板】 演讲稿常用句式： 开头： I appreciate... 我感谢…… Thank you for... 感谢您…… It is/was my honor... 我很荣幸…… On behalf of... 代表…… Id be happy to...我很高兴…… 正文： The topic of my speech today is...今天我演讲的主题是…… What I am going to talk about today is... 今天我想讲的是……
