今天很高兴可以站在这里与大家进行演讲。我会与大家讨论一下什么是礼貌。那么什么是礼貌呢？礼貌在我们的生活中有着重要的作用，是我们个人素质的综合表现。很多大人认为讲礼貌的应该是小孩，而不是大人，其实这个观点是错的，因为礼貌是个人素质的表现。当然，在不同的国家，礼貌的定义也会有所不同，但有一个礼貌却是全世界都会感受到温暖的，那就是微笑。但我们在我国旅行时，应该了解当地的礼貌，否则就会惹出笑话了。做一个有礼貌的人，会是你更加受欢迎。
要求：无语法错误，使用较为简单的词组与单词。谢谢！
Today I am pleased to be able to stand here with you to prayer. I will discuss with you what is polite. So what is it polite? Courtesy in our lives plays an important role in the personal qualities of our overall performance. Many adults may think that courtesy should be the child, rather than adults, in fact, this view is wrong, because courtesy is a personal quality performance. Of course, in different countries also vary the definition of courtesy, but it is a courtesy of the world will feel the warmth, and that is smile. But we travel in our country, we should understand local manners, or else it will stir up joking. To be a polite person, you will be more welcome.
