求一篇初中生物演讲稿（根据人教版教材）
生物，是一门非常深奥的学科。
表面上，他并不重要。
但实际上生物牵扯到了人的生殖发育，人的起源，包括其他人的知识，例如为什么父母生下的孩子会是男是女，有的生物为什么没有授粉也可以生殖
为什么
这就是生物了。
生物，包括植物、动物、以及昆虫等。
分细一点，植物又包括裸子植物，被子植物；动物又分：鱼类、两栖类、爬行类、鸟类以及哺乳类；至于昆虫，更是多不胜数了。
每一种生物，都是生物学上的一张名片，而这个名片，仅仅只是千千万万生物种中的一类。
生物高深吗
不，其实他并不高深，但它牵扯到的不单单是一点点。
地球最初的生物，恐龙的出现于灭绝，人的进化。
这些问题，看起来简单，但对于整个人类以及整个地球而言，都是极为重要的。
我们可能单一的去看生物，只把它当做一个副科，学不学都无所谓。
但是，同学们，难道你们不想了解生物起源的秘密吗
不想了解人类的进化过程吗
不想了解那些看似平常的鱼、鸟、兽身上隐藏着的秘密吗
同学们，让我们拿起手中的课本，翻开崭新的一页，去了解这些隐藏在世界深处的秘密吧
不知道是学生还是老师，反正我是学生，写的有一点点散，不要介意哈。

生物课代表竞选演讲稿
尊敬的老师，亲爱的同学们： 大家好，我是xxx。
俗话说“一年之季在于春”，我们班展开了“竞选”班委的活动，我左思右想，决定竞选生物课代表，因为我觉得我竞选这个职务有三点优势： 1：自从我接触生物开始，我就迷上了生物，因为我觉得生物是那么的神奇、是那么的奥妙，而且还是那么的有趣。
在课外书上，我学会了许多课本上没有的知识，我将会和大家一起来学习这些知识。
2：平时我一定会在课上认真听讲，积极发言，希望大家监督。
当然，在当上课代表后我将会更加努力的学习，争取取得更好的成绩，为班级争光。
3：我上初中开始，会积极参加生物课外兴趣小组，并且不影响学习。
所以，我认为我是最适合的人选。
另外，如果我当上了生物课代表，我将会和大家一起钻研生物知识，探索生物王国里面的奥妙，使我们班的生物成绩有一个质的飞跃，并且争取在学年中名列前茅
如果选不上，我也不会气馁，我将继续努力学习，克服自身的不足，使自己成为一个对祖国、对人民、对社会有用的人才。
人们常常说“。

初中学习方法演讲稿
学习方讲稿老师们、同学们：大
很荣幸我能在这大家分享我的学习经验。
为要想取得一个理想的成绩，就必须要有一个好的学习方法。
学习方法因人而异，但是，好的学习方法绝对离不开课前认真预习、上课认真听讲和课后及时复习这三个方面。
1.认真预习。
预习在整个学习知识的过程中有着不可低估的作用。
预习是学生自主的学习行为。
在整个学习的过程中，如果学生课前没有做好准备的话，听课就会十分被动，而且还会手忙脚乱，课堂效率也不会很高，在复习的时候更是显的费时费力。
如果学生课前有准备，那么上课的时候就会心中有数，课堂笔记也就有了重点，对老师的提问反应就会更快，这样不仅提高了课堂效率，而且还能增强学生的自信心。
2.抓住课堂。
学习重在平时的努力上，不适于突击复习。
平日里学习最重要的是课堂的40分钟，听讲要聚精会神，思维紧跟老师走。
要集中注意力听讲，集中注意力、专心致志听讲才能学有所得；心不在焉、心猿意马肯

This forum’s theme is China: the next 50 years. China is a large developing socialist country, and its future development will not only directly affect the future of the Chinese people, but will also have important impact on the development and progress of Asia and the world. Over the past hundred-odd years, the Chinese people have gone through storm and stress, and in the course of vigorous struggle they have accomplished a great historic transformation. New China’s 50 years of development have resulted in accomplishments that have astonished the world. Only six years ago, in this Lujiazui District of Shanghai’s Pudong area, where we are gathered this evening, there were only run-down houses and farms. Now it is a vibrant modern financial and business zone, full of highrise buildings. Over fifty years ago, I was in Shanghai attending university. At that time, I had a deep sense of the poverty, backwardness and feebleness of the old China. It was then that I decided to devote myself to the noble task of building an independent, free, democratic, unified, rich and powerful New China, and I have been struggling for that to this very day. Fourteen years ago, I became mayor of Shanghai and experienced the process of reform, opening-up and modernization in this, China’s biggest city. I’m sure that all of you have seen with your own eyes the constant and unceasing transformation of Shanghai. The growth of Shanghai is one reflection of the enormous changes taking place in China. In the first 50 years of the 20th century, the Chinese people made unflagging efforts to change the tragic fate that had been theirs ever since the Opium War. After arduous and valiant struggle, they finally ended their semi-colonial and semi-feudal history, won independence for the nation and freedom for the people, and founded the People’s Republic of China under the leadership of the Communist Party of China. In the latter half of the 20th century, relying on their own efforts, the Chinese people went all out to make their country strong, and began socialist construction. On the poor and deprived foundation of old China, they built a relatively complete industrial structure and national economic framework, raising the levels of their cultural and material lives significantly. China started marching forward steadily toward prosperity. Now, the Chinese people are confidently taking the road to the future, the road of socialism with Chinese characteristics pioneered by Comrade Deng Xiaoping. These historic initiatives of the Chinese people have fundamentally transformed the tragic fate of modern China, and they are also great contributions made by the Chinese people to the cause of human progress. At this moment in time, when we are about to step into the 21st century and look ahead at the prospects for the next 50 years, we are filled with confidence. The Chinese people will firmly and unswervingly follow the path of reform and opening-up. Our goal is to realize modernization by the middle of the coming century, to make our country a wealthy, strong, democratic and civilized modern socialist country, and to achieve the great revival of the Chinese nation. Here, I would like to speak to you about some basic values of the Chinese people. Without an understanding of these, it is difficult to make sense of present and future events in China. The Chinese people have always respected the dignity and worth of human beings. The Communist Party of China led the people in revolution, construction and reform for the very purpose of realizing freedom, democracy and human rights for all the people of China. The great vitality displayed nowadays in China vividly demonstrates the tremendous space that the Chinese people have to freely and democratically exercise their creativity. China has a population of over 1.2 billion, but its social production is still not well developed, and we must first and foremost safeguard the people’s rights to survival and development; otherwise we cannot even begin to talk about other rights. The fact that China has assured the rights to survival and development of over 1.2 billion people is a major contribution to the cause of the progress of human rights all over the world. The Chinese people advocate the close interlinking of collective human rights with individual human rights, of economic, social and cultural rights with citizens’ political rights. This is the road we must take for the cause of promoting human rights in light of China’s national conditions. The Chinese people have always insisted on independence. They cherish the rights of independence that they have won over a long period of struggle, and they resolutely uphold the right of all people to enjoy these rights. We also believe that every country has the right to choose the social system, ideology, economic system and path of development that suit its national conditions. Countries with different social systems should respect each other’s sovereignty and territorial integrity; they should treat each other as equals and coexist peacefully. We oppose any efforts by any country to impose its own social system and ideology on another country. The Chinese people have always loved freedom and peace. The Chinese people have suffered greatly from wars and invasions in modern times, and they feel deeply how precious peace is. As it engages in modernization, China needs a peaceful international environment. We hope that all people will be able to live in a world without war and without violence. China carries out a foreign policy with peace as its goal, and resolutely opposes any acts that endanger world peace. China’s development does not pose a threat to anyone, instead, it will only help to advance world peace, stability and development. It is the Chinese people’s solemn promise to the world never to seek hegemony. The Chinese people have always prized national unity. To safeguard the unity of the motherland is the firm aspiration of the entire Chinese people. Hong Kong has already returned to the motherland; Macao will return on December 20 this year. It is certain that the Taiwan question will eventually be resolved. No country will allow its own territory to be split off, nor will it allow any foreign force to create or support such a split. Our guideline for solving the Taiwan question is peaceful reunification and one country, two systems. In resolving the Taiwan question, we will not undertake to renounce the use of force precisely for the purpose of bringing about a peaceful resolution of the Taiwan question. The Chinese people have both the determination and ability to achieve the complete reunification of their motherland. The series of recent severe earthquakes that occurred in the region of Taiwan weight heavily on the heart of everyone in China. I would like to take this opportunity to again express profound condolences to our compatriots in Taiwan who have suffered from the earthquakes. The world is a colorful and varied one. The people of each country follow the path of development they have chosen for themselves and pursue their own ideals. This is an I inevitable demand and basic criterion for the progress of human civilization and world democracy. It is therefore an unstoppable tide of history. We believe that the different social systems that exist in the world and the dissimilarities in political beliefs should not be used as obstacles to the various kinds of normal economic and technological cooperation and exchange. All you business leaders tonight are outstanding achievers in your respective fields. You have a wealth of successful experiences and strategic vision. Set your eyes on China. China welcomes you. China’s modernization needs your participation, and China’s economic development will also offer you tremendous opportunities. I hope that Chinese enterprises will learn from the advanced experiences of foreign enterprises. They must go out and temper themselves in the winds and storms of economic globalization, and build up their own competitiveness. The Chinese government will offer good terms to and create a better environment for foreign enterprises investing here. China’s development and that of other countries, the development of the South and that of the North in the world are all interlinked and complementary. They should step up exchanges and cooperation on the basis of equality and mutual benefit. The Chinese people hope to lead peaceful and happy lives, and also hope that the people of other countries will enjoy peaceful and happy lives. The people of all countries should strive hand in hand to overcome all the challenges to human survival, protect the ecological environment, narrow the gap between rich and poor, build a just and rational international economic order, and achieve common development and universal prosperity. The developed countries should assume more responsibilities in this regard, and the developing countries should constantly seek to do better for themselves. The human race has reached another historic moment---the turn of a century and a change of millennium. The initiative lies in the hands of the people of each country. Let us make a joint effort for the noble cause of advancing peace and human progress! I strongly believe that China will have a better tomorrow and that the world will have a better tomorrow. Thank you. 初中生英语演讲稿 同学们： 当你们看着可爱的动画片，玩着迷人的电脑游戏，坐上快速的列车，接听着越洋电话的时候，……你可曾意识到科学的力量，科学不仅改变了这个世界，也改变了我们的生活，科学就在我们身边。
翻开20世纪的壮丽篇章，我们发现人类在这百年中不仅经历了血与火的洗礼，更创造了无数科学奇迹。
19世纪法国著名科幻小说家凡尔纳的虚构，当时让人不可思议，他所幻想的登月旅行、飞机、远射程炮等，在20世纪都一一成为现实。
在21世纪的今天，高科技更是无处不在。
作为跨世纪的一代，我们又该以怎样的姿态去适应新世纪，担起新世纪的重担呢
科学技术的日新月异，使得科学不只为尖端技术服务，也越来越多地渗透到我们的日常生活之中，这就需要正处于青少年时代的我们热爱科学，学习科学。
参加科技“五小”比赛、阅读科技书籍，使我明白了许多道理。
精密的机器人，不用燃料的汽车，虚拟的足球赛，高科技信息的传送等等，一个个生动有趣的现象，激起了我探索科学的愿望。
我们每个人都要学习科学，传播文明，在享受新生活的同时，更要创造新生活，如今，科技产品的更新换代不断加快，可视电视、电脑上网、心脏起搏器，已经不算新鲜了。
从1901年发明的真空吸尘器，到人造地球卫星、载人宇宙飞船，科技在不同领域里显示出了强大的力量。
电子产业、通讯技术的日益普及，纳米技术、超导材料的广泛应用，不久的一天，也许就在你的餐桌上，会出现像太空青椒、人造牛排等生物工程食品。
学习科学技术，不仅仅是为了成为科学家，也是为了能适应生活，更为了能成为新世纪的主人，担起新世纪，为国家建设，为人类文明做出贡献。
新中国成立以来，我国的科技发展突飞猛进，人工合成胰岛素、断手再植、杂交水稻、爆炸原子弹和氢弹、发射人造卫星和飞船等等，这些令世人瞩目的科技成就，大大缩短了我国和先进国家的科学技术的差距，为我国的现代化建设注入了活力。
爷爷说“科学技术是第一生产力”，的确如此，科学为我们祖国的腾飞插上了翅膀。
主席曾对青年说，世界是你们的，也是我们的，但归根结底是你们的。
这句话，饱含了长辈们对我们的殷切期望。
如果说长辈们用辛勤的劳动建设了20世纪的祖国，那么，我们就应该以知识、以科学担起新世纪的重担。
同学们，我们正处于成长发育阶段，学习科学，让我们从小做起。
我们要努力学好各种文化课，因为这是一切学习的基础；同时，对各种适合我们小学生看的科普书籍、报刊，最好在课余多阅读一些；还应该积极动手搞各种科学小实验、小制作，写科学小论文等，培养对科学的兴趣。
长此下去，我们一定能够热爱科学，拥有丰富的科学知识。
人类的智慧是无限的，无论是美国的挑战者号爆炸，还是全球计算机病毒的升级，从来都不能阻止人类的科技进步。
“知识就是力量”，培根这句脍炙人口的格言不知激励了多少渴求知识的人。
如今，让我们也用它来勉励自己，做一个热爱科学的新一代，担起新世纪的重任，为我们祖国的明天，谱写出更加辉煌的诗篇
谢谢大家。
Schoolmates: When you look the lovable animated cartoon, plays is in a stew human's computer games, rides the fast train, is answering transoceanic telephone time, ......Not only your might once realize the science the strength, the science changed this world, also changed our life, the science side us. Opens for the 20th century the grand chapters, not only we discovered the humanity to experience the blood and the fire baptism in these hundred years, has created the innumerable scientific miracles. 19th century France famous science fiction writer of fiction verne fictionalizing, at that time let the human be inconceivable, he fantasized moon landing travel, the airplane, the long-range gun and so on, all 11 became the reality in the 20th century. In the 21st century today, the high tech is ubiquitous. As cross-century one generation, how posture should we adapt the new century by, the load get up the new century heavy burden? Not only science and technology changing with each new day, causes the science to serve for the most advanced technique, also more and more many seeps to during ours daily life, this needs us who is in the young people time to deeply love the science, the study science. Participation science and technology “five small” competition, reading science and technology books, caused me to understand many truths. The precise robot, does not use the fuel the automobile, the hypothesized soccer game, high tech information transmission and so on, each one vivid interesting phenomena, aroused me to explore the science the desire. Our each people all want to study the science, the dissemination civilization, while enjoys the new life, must create the new life, now, the technical product renewal speeds up unceasingly, the visible television, the computer surfer, the pacemaker, already did not calculate was fresh. Vacuum cleaner invented which from 1901, to the artificial earth satellite, carried the human spaceship, the science and technology demonstrates the formidable strength in the different domain. Electronic industry, communication technology daily popularization, nanotechnology, superconductivity material widespread application, soon one day, perhaps in yours dinner table, can appear likely bio-engineering foods and so on outer space green pepper, man-made beefsteak. Studies the science and technology, is not merely in order to become the scientist, also is for can adapt the life, more has been able to become the new century the master, the load gets up the new century, is the national construction, makes the contribution for the human culture. Since new China had been established, our country's technical development progresses by leaps and bounds, the synthesized insulin, finishes a job plants, the hybrid rice again, explodes atomic bomb and hydrogen bomb, launch satellite and airship and so on, these technical achievement which focuses attention on the common people, reduced our country and the advanced countries science and technology disparity greatly, has poured into the vigor for our country's modernization. Grandpa Deng Xiaoping said “the science and technology is the first productive forces”, indeed so, the science has inserted the wing for our motherland soaring. Chairman Mao Zedong once said to the youth that, the world was you, also is we, but is your in the final analysis. This speech, has been full of the elders to our earnest expectation. If the elders have constructed the 20th century motherlands with the industrious work, that, we should by the knowledge, get up the new century heavy burden by the scientific load. Schoolmates, we are being at the growth developmental stage, the study science, lets us start since childhood. We must learn each kind of literacy class diligently, because this is all study foundation; At the same time, to each kind the popular science books, the publication which suits our elementary student to look, should better read some in the after school; Also should begin to do each science small experiment, the small manufacture positively, writes the science small paper and so on, raises to the science interest. Long this gets down, we can certainly deeply love the science, has the rich scientific knowledge. Humanity's wisdom is infinite, regardless of is US's Challenger number detonation, the whole world computer virus' promotion, always all cannot prevent humanity's advance in technology. “The knowledge is the strength”, Bacon this sentence enjoys great popularity the maxim did not know had driven how many earnestly seeks the knowledge human. Now, lets us also use it to encourage oneself, makes one to deeply love the science the new generation, the load gets up the new century heavy responsibility, for our motherland tomorrow, will compose a more magnificent poem! Thanks everybody.

初中开学典礼演讲稿
尊敬的老师、亲爱的同学们： 大家好
我们的暑假，在欢笑中悄悄落下了帷幕，一个崭新的学期，在秋日暖阳的照耀下，向我们走来。
新的学期，新的知识，新的目标，新的责任，这一切都是新的。
也许昨天你拥有辉煌，也许过去你曾遭受打击，但是过去的都已过去，忘记昨日的成功与失败，要相信未来在我们手中
我们应该以全新的姿态来到校园，我们应该充满信心地面对今后的学习生活。
我们应该相信，只要努力没有什么事是我们做不到的
七年级的同学们，告别了小学生活的你们，即将走入一个新奇的世界——初中。
这里是你们今后学习、生活的地方，这里有许多丰富多彩的知识等你们去学习，去发现，这里有你们的理想与抱负，这里还有更长更远的路要你们走下去。
在这条通往理想的路上，会有坎坷、崎岖，会荆棘丛生、迷雾弥漫，甚至风雨也会不期而至，对自己说：“不用怕，我能行
”你们是展翅的雏鹰，坚持走下去，一定能找到属于自己的那片广阔的苍穹
八年级的同学们，初二，是至关重要的一个学期，因为我们面临着地理、生物的中考，在这个学期里，我们必须投入更多、更大的精力用在学习上，我们要善于利用时间、合理分配精力、学会排除干扰、提高学习效率，我们更要把握自习课上的分分秒秒，在伏尔泰的作品中曾经提到过一个谜语：世界上有一样东西，它是最长的也是最短的，它是最快的也是最慢的，它最不受重视但却又最受惋惜；没有它，什么事也无法完成，这样的东西可以使你渺小的消灭，也可以使你伟大的永续不绝。
你想到这样唯一的东西是什么了吗
它就是时间。
所以我们要充分利用时间掌握各种知识技能，攀登科学知识的高峰，做一个思想好、品德高的优秀人才，将来能在社会实践中谦虚谨慎，积极探索，勇于开拓，不断提高自身素质，做有道德，有理想、有文化、有纪律的新世纪接班人。
九年级的大哥哥、大姐姐们初三的生活自然是艰苦的，它需要你付出大量时间精力同时也要学会面对一切压力，良好的心态十分重要，这就需要一颗很豁达又善于发现的心去体验学习生活中的乐趣。
秋天的硕果不属于春天的赏花人，而属于春天的耕耘者。
你在生命的春天播下创造的种子，必将迎来金色的生命的秋天
。
在此，我们衷心祝愿所有初三的大哥哥大姐姐们最后取得优异的成绩，骄傲的为自己竖起大拇指。
我们都知道，徐州正在创建国家环保模范城市，爱护校园环境也是我们应尽的责任。
在这里，我们倡议：请大家自觉去维护校园环境，不乱扔垃圾，随手拾起废纸，不在课桌椅上乱刻乱画，要严格遵守学校的日常行为规范，自觉地约束自己的行为，使一日常规中的各项要求逐渐变为自觉的行动；同时也要遵守社会秩序，培养高尚的社会公德，向全社会展示十三中学生良好的风采。
此外，我们还要倡导和支持绿色消费，弘扬生态文明，从点滴做起，使用无磷洗衣粉，购买绿色环保产品，少用一次性餐具和塑料袋，杜绝白色污染。
共同参与和履行植树造林活动，保护生态环境，爱护城市树木，美化家居环境，拒绝食用野生动物，维护生态平衡，推进人与自然和谐共处。
共同维护和遵守环保法律法规，积极举报环境违法行为，参与社会环境监督，参与环境公益活动，宣传环保理念，共同建设环境友好型社会。
老师们、同学们，环境是我们赖以生存的基础，保护环境是每一个公民义不容辞的责任。
让环保进入我们每一个家庭，成为我们的生活理念，让创模变为我们每一个人的行动。
让我们携手共进，为创建国家环保模范城市而努力奋斗
最后，祝愿亲爱的同学学习进步，健康成长
祝愿我们的老师事业成功，心想事成
祝愿我们的学校和谐、平安、大步向前，再创辉煌
我的讲话完了，谢谢大家。
——————————————————————————————————————————尊敬的老师，亲爱的同学们，大家好： 告别了炎夏的不安与躁动，凉爽怡人的秋天向我们展开了笑颜；告别了假期的安静与沉寂，期待的校园又充满了欢声笑语。
九月 日，对于学校，对于教师，是个激动人心的日子。
新学期，我们带着希望，带着憧憬，怀着激动，怀着兴奋。
时间总是流逝，盛年不会重来。
一年一度，送往迎来，新的学期在金秋清爽的风中，在清脆的鸽哨中，又开始了她的历史行程；列车已经行驶出车站，我们师生将共同承载新的希望，奔向远方。
饮水思源，我们更加珍惜甜美的泉水；收获的时候，感谢播种你的人，春华秋实，我们更加明白劳动的艰辛；成功的时候，投桃报李，我们更加懂得生命的意义。
让我们以自己的爱师情怀，洗去老师衣袖上的粉笔尘埃，抹去老师额角上的操劳皱纹，滋润老师发干的喉咙，让老师更睿智、更激情、更艺术的奏响育人的华美乐章。
在此，我由衷的说一声：“老师，您辛苦了
” 对我们九年级的同学来说，是在初中学习的最后一个学年的开端，让我们以只争朝夕的精神和精益求精的学风，总结前两个学年的学习经验，调整好心态，以最好的学习方法，最佳的精神状态，投入到初三的学习中来，集中思想，发奋学习，多学多问。
同时也要注意身体，劳逸结合，使自己在初中的最后一个学年来一个腾飞。
有人说，初三是条汹涌的大河，但只要我们紧握理想的船桨，划过去，就能欣赏到美好的风景。
的确如此，也许我们会觉得初三的生活会很枯燥、无味，但只要我们真正懂得了学习的目的，紧张的学习就不枯燥了，就像我们经常说的“那是一种吃到苦而又不觉得苦的境界”。
我们还有很长的路要走，没有人可以预料我们下一秒会是怎样，但是这一秒却很真实，只有把握现在，才有资格站在时间的前端，对着未来骄傲地挥手。
上届的学长学姐已写下辉煌，奋斗的火炬已正式交接在我们手上，如今，该是我们书写辉煌的时候，该是我们为校争光的时候，该是我们放飞梦想的时候
对你来说，初三的每一天，每一节课，每一分钟，甚至是每一秒钟，都是宝贵的，你要时时刻刻为自己的光明前程增加筹码，假如你不精心，稍微一松就会使你痛失良机，时间一长，你将会离自己人生的“精彩”差很远的距离。
同学们，机遇将至，怎样紧紧地扼住生命的咽喉，成为命运的主宰，成为生活的强者，每个学子心中都有一个答案。
在这个时刻，做逃兵，绝不是三井子职中人，那样会使你的一生蒙羞。
请初三的每位学子牢牢记住：追求卓越，超越极限，在绝望中寻找希望，你就可以成就辉煌的人生。
对八年级的同学们来说，是全面掌握知识体系，决胜初中的关键时期，让我们把更多的时间放在思考上，多做知识系统和学习方法的总结，同时加强锻炼，为九年的冲刺做好准备。
初二是容易使人沉沦的一年，是免疫能力衰退的一年，是中考前命运不定数最大的一年，同学们，你面临这个学年，将何去何从
我认为，首先要战胜自己，把握好自己的人生航向，全力以赴投身于学习之中，争分夺秒，抢抓这个可以逆转人生厄运，走向辉煌的最佳时机，下定决心利用这个黄金时期努力实现自我的超越，机不可失，时不再来，人生这样的机会或许只有一次，相信吧，拼搏能改变命运，奋斗可以拯救未来
你们肩负着承上启下的重任，希望你们再接再励，努力拼搏，为明年的初三学习打好厚实的基础，争取在各项常规工作中做好榜样，一年更比一年好
初一新生们，你们是青屏初中的新鲜血液，希望你们尽快适应新的环境，在平时努力做到：学会做人，学会做事，学会生活，学会学习，学会合作。
你们初来乍到，年龄尚小，要注意调整心态，适应新的环境。
初中有别于小学的教学风格，节奏快，讲究精讲精练，精练，知识面宽，对抽象思维要求高，加之教师的教学风格不同，会给你们带来一些影响和短暂的不适应，所以你们要有思想准备，要学会尽快适应新的环境、新的教师、新的教学方法，努力使自己走进优秀的行列，很快地站稳脚跟。
其次，你们要有远大的理想，新的征程新的挑战又开始了，我们一切要从基础做起，努力在新的环境中创造佳绩，展示自我。
要严格要求自己，构建思想的坚实堡垒，筑起抵御外界不良习俗的坚固防线。
最后，送给同学们一句话：不是每一道江流都能入海，不流动的便成了死湖，不是每一粒种子都能成树，不生长的便成了空壳。
新的学期又开始了，在我们每个人的面前都摊开了一张新白纸，那么我们将如何在这张白纸上画出人生的又一幅精彩的画卷呢
同学们，选择了勤勉和奋斗，也就选择了希望与收获；选择了纪律与约束，也就选择了理智与自由；选择了痛苦与艰难，也就选择了练达与成熟；选择了拼搏与超越，也就选择了成功与辉煌
那么就请用我们的勤奋和汗水，用我们的智慧和热情，抓住这宝贵的今天，师生团结一心，努力在今朝，去创造美好的明天吧。
同学们，拿起自己的信心与勇气，在自己的心底刻上刚毅与坚强，我们要出发了，不再留恋过去的辉煌，去面对更艰苦更灿烂的人生；不要害怕会迷失方向，朝着前方，挺起你的胸膛。
相信，经过风雨的洗礼，我们会更坚强，经过一次次失败与苦难，我们会更加珍惜这些成长。
祝愿大家在今后的旅途中，劈荆斩棘永争先。
相信自己，我能行
让我们牢记师友的热切期盼，扬紧自己的理想之帆播种新希望，放飞新梦想，踏上新征程，创造新成绩，在学校的这片热土上，同心，同德，同行，共同铸造新的辉煌
——————————————————————————————————————————祝演讲成功~
