自我介绍中文演讲稿
尊敬的各位老师同学： 大家好
此次能成为这里的学生，我从内心当中非常高兴，我由衷的感谢学校给我这次千载难逢的机会。
我是来自大专2班的……，曾在校期间，任班级干部长达八年之久，培养了我在管理班级、人际交往、为人处事等方面的能力，使我真正理解了当一名干部的本质所在，深悟出无论从事任何工作，都要尽职尽责、勇于奉献、为民服务的深刻道理。
由此我的人生格言是：在学生面前我愿做一头终日劳作的“牛”，这是我的精神特征，用一句名人的话语“俯首甘为儒子牛”。
各位老师，同学们，如果我加入学生会，我将会用我上述所说的本质精神服务于大家，最大的激情投入大家，全部的爱奉献给大家。
我虽是集体中的一员，但我会把我全部的精力投入我们这个大集体之中，使我们学生会中的各项工作达到尽善尽美，努力构建成和谐的完善的，使全体师生都满意的学生会。
现在，我向全体师生宣誓：1在校各级领导的支持下，在校各项政策制度下，全力配合学生会的成员，把各项工作做实，做强，做好；2在和谐这面旗帜下，把学生会的大事小事处理的稳帖妥当，时时处处，方方面面都做到完美无瑕，把我校学生会构建成和谐的和睦的，实力最强的，最优秀的学生会；3在学生会中不突出个人主义，不提倡个人主义，无论大小事，全校会商议后，再去实行，达到妥，帖，稳，准，实五项要求。
此次我竟选的是学生会副主席之职，如果成功，我定当全力以赴，如果失败，我也会努力做一个好的小我，’人生岂非也正如一局棋，输赢以何必太认真呢，’重在参与。
学生：dxq 尊敬的各位老师，各位同学： 大家好
非常高兴能来到我们班级，也很高兴认识大家；我张加贝，为什么叫加贝呢，因为我爸爸姓张，我妈妈姓贺，拆开就是张加贝了（可以问问妈妈自己名字的由来，给大家讲一讲，会给同学们带来深刻的印象）。
我爱好还是比较广泛的，我喜欢跳舞，尤其是拉丁，我很喜欢他的节奏感和舞步，所以我的性格也是像拉丁一样热情奔放。
当然我还有不同的自己，我也喜欢读书，尤其是童话书，我常常做梦自己成为童话里的主人公，像白雪公主与七个小矮人，阿里巴巴四十大盗都是我很喜欢的。
（可以介绍自己的爱好，爱好比较对立的印象更深刻，还比如游泳与画画，唱歌与书法，比较对立的最好）。
更重要的是我很喜欢交朋友，我愿用我的热情拥抱每一位同学，我愿和你们成为好朋友。
下面我为大家跳支舞，希望大家喜欢。
（或唱支歌，迅速做幅画，都是很好的） 跳完后，谢谢大家。

Ladies and Gentlemen, there is appreciation of this opportunity to let me stand here. Today, I want and what we are talking about an inspirational movie:海琴师(the legend of 1900). In 1900 the first day of landing in New York just cruise No. Virginia, Tim Danny Boodman coal workers found a baby abandoned by passengers, he will name the baby 1900, to commemorate the child in the new century, the first day of by his adoption. Until the death of eight-year-old Danny Boodman when, in 1900 only came into contact with music, and at 21 days, miraculously learned how to play the piano. A few years later, adults No. 1900, Virginia became the band's pianist, in a storm, he met a being seasick the Max, two people very投. From then on, max became the confidant of his life. 1900 became a real pianist, although he had never been under the boat, but has the reputation of Yuanyang. Accepted ancestor of jazz Jelly Roll Morto challenge and eventually beat him, so 1900 has become famous for, but he still refused to disembark on the stubborn land, because of 1900, the people of the world aspire to live too far away. Love at first sight until he encountered the girl, for love, 1900, finally intend to go ashore to find the girl. The day he disembarked ladder away, but when he is about to set foot on land, he looked blank Connaught large New York City, staring for a while, then back, back on board. Max said to him, I no longer had disembarked. Sure enough, the end of his life, 1900 people who have no boats. Until many years, World War, 1900 with the old No. Virginia was a bomb to smash together at the vast sea. 1900, let me see him without the secular, easy, natural, grace. The temptation of the human world, fame lee bunk, he has turned a blind eye, he must be immersed in their own music and have no time for the sound of things outside distraction. There is no doubt that 1900 is a genius, he did not disembark, he chose his fantasy world. I would rather give up their lives, they were reluctant to find in a world at the end of life, and I walked half of the stop, not because I can see, but I have not seen ... ... At least, he has chosen has its own way, live for their own sake, 88 keys on the creation of the infinite, beautiful, free music, enriching his life is limited and simple. However, we still are not in order to pressure for others to live, for some, but not at your fingertips Value of those around him did not touch too bright. Watching this movie, we should examine ourselves, we tired of running in this growing up in a materialistic materialistic world, and torture of the depths of his soul, for what we live, how do we live, then what is the support of our go live. It tells us: We can not belief, but must have faith. Movies most people will undoubtedly commendable movie clips are 1900 and Jelly Roll Morto Doo Guoqin part, especially the 1900 final concert of a Perpetual Motion (enduring movement), this song all the black keys are playing the piano, and also is entirely chromatic playing, required very high skills in order to play the piano. • Ross starring Tim (Tim Roth) is a professional actor, not piano, but in shooting the movie before the meeting hungry临时脚some basic fingering, and then by special methods of treatment. The following, please appreciate the U.S. in 1900 playing the song Perpetual Motion.
