第一篇:硕士答辩演讲稿

各位专家、教授,各位同学:

上午好!

我是xxx,来自xxxx,我所研究的方向口语交际教学,论文题目为《xxxx 》。

第一, 为什么选这样一个论题来进行研究?

首先,多年的教学让我深深地为我们中学生的口语表达能力感到忧虑,许多来自农村的孩子,虽然学习很努力,学习成绩也不错,但是,他们往往更擅长案头作业,而面对需要口头表述的时候,却往往辞不达意,说者惶惶不安,听着不知所云;而相反,一些来自家境良好的城市里的孩子,却常常出言不逊,不懂得与人相处交际的基本常识。以上两种情况,都严重的影响了人际之间的交流、沟通,对孩子的身心发展带来了许多负面的影响,同时也为校园同学、师生之间的交流带来的许多负面的影响,这种负面影响,必然会延伸到社会、延伸到个体的终身发展。

其次,高中阶段,是学生基础教育的最后一个时段,学生将由此走入两个入口:高等教育和社会就业,无论是哪个入口,都将不太会再有机会接受系统的口语表达训练,特别是升入理工科专业的学生。而且,高中生的特殊的年龄特点,性格特征、心理特征都处于成型的关键期,适时的引导将极大地有益于个体心理素质良好完善。

再次,新课程的改革如火如荼,口语交际教学的美好蓝图也颇令人心神向往,高中语文“新课标”中“第二部分课程目标”寥寥的五千来字的篇幅,对口语交际方面的要求涉及十余次之多,同时对口语教学的理念诠释,也有了一个质的飞跃(从口语教学到口语交际教学)。但是,在改革轰轰烈烈的进行的时候,我们还是应该看到具体实施上的重重困难,尤其是口语交际教学领域还处于一个冷冷清清的局面。与许多的改革一样,目前依然存在着理论与实践相剥离的状况,口语交际教学实施的无所依从,是这种剥离的一个重要的因素。目前虽然有很多的理论研究,但大多数的理论研究仅仅着眼与技术操作层面,只是把它作为语文教学的一个子系统来研究,没有深层挖掘口语交际教学与语言学、生理学、心理学以及社会学等方面的联系,同时,很少有探讨口语交际教学考核体系的研究成果,许多老师虽然很愿意在此方面对学生有所帮助,但终因操作的难度和大环境的约束而望洋兴叹,知难而退。

因而,我希望能够通过我的研究,为口语交际教学课程的改革的做一次破冰之行。

第二,论文框架的构建

基于以上的原因,我把握的研究定位于整体的规划,我认为口语教学的问题不是在于某一点的查漏补缺,而是整体的空白状况的改观,并且对整体教学理念的重新认识。我在对现实教学状况和现有的教学教材比较的基础上,提出了自己的对口语交际教学认识和规划,我认为,口语交际教学具有依赖于言语教学又独立于语言之外的特点,它是一个基于语言、生理、心理之上的学科,成功的高中口语交际教学必须分析高中生的特征、特点,在义务教育阶段教学的基础之上,制订一系列有的放矢的教学目标,在教学过程中,它必须拥有独立的时间表,独立的互动场景和独立的师生互动媒介物,同时,要有一套完善的评价体系来支撑教学的进行。

在我的研究中,针对高中生的特点,提出了相对完整的一套三年一贯制的教学方案,从个体生理、心理到社会适应性呈梯度进展,并且每个年级的都有课案举例,以便于操作的实用功能,同时,也提出了几种口语交际教学能力评价的几种方案,在各自得信度和效度上进行论证,以期为成熟的测试方法的出台提供依据性的思想。

第三, 研究的几点说明

在为期一年的研究过程中,我阅读了大量的有关文献资料,涉猎的领域广泛,并且走访了各个不同层面的高中段学校,在自然的情景之下采集样本,研制和发放了问卷调查,并进行了实证研究,把质的研究和量的研究进行有机的结合。

当然,由于水平的欠缺,我的研究中必然会出现这样那样的不足或漏洞,恳切的希望教授、专家的批评和指导。

在此,我要感谢的是在我的研究过程中给与我支持的所有的人,特别是我的导师李海林教授,如果没有他们的帮助,我想我的研究一定不能达到这个境界。也感谢在座的各位评委,希望得到你们更多的指导。

第二篇:硕士答辩演讲稿

各位老师:

上午好!

我叫李康,是XXXX建筑与土木工程的学生,我的毕业论文题目是《带防屈曲支撑钢连梁联肢墙抗震性能及工程应用研究》,指导老师是张利教授。在我的论文写作期间曹老师给予了悉心的指导,这才使得我的论文能够如期顺利完成,在此,我向我的导师表示深深的谢意!

向各位老师不辞辛苦参加我的论文答辩表示衷心的感谢,下面我将论文的选题背景、研究内容以及不足之处向各位老师做以汇报,恳请各位老师批评指导。

首先,本篇论文的选题背景。

目前,在工程上应用最多的就是普通配筋的连梁了,因为这种连梁形式构造容易、施工很方便,造价低,在国内外都得到了广泛应用。对于跨高比较大的连梁来说,受力性能也较好,这也是其在国内外得到应用的主要原因之一。

对于小跨高比的普通配筋连梁,在众多国内外学者的研究中新西兰的著名学者 T.Paulay 对它的研究较多,他通过试验研究了跨高比小于 1.5 的普通配筋连梁的受力性能,研究结果表明[2]:一旦连梁上出现斜裂缝,连梁里的上、下纵筋将全部受拉,随后拉应力一直会延伸到连梁的受压部位,这样就会导致连梁实际的抗弯能力比传统连梁的抗弯能力偏小。这种情况下,继续施加外荷载,在经过几次较大的受力循环后,连梁两端截面配的上下纵筋都会因受拉屈服,钢筋逐渐伸长,梁端的垂直裂缝显著扩展开来。当施加反向荷载时,裂缝无法再闭合。再次反向施加荷载,产生裂缝的截面基本上已经退出了工作,作用在连梁上的剪力只能由销栓力承担,但是销栓能承担的剪力毕竟很少,销栓退出工作,继而截面沿裂缝产生滑动,最终导致“受压区”裂缝两侧的混凝土在摩擦错动中发生剪压破碎。

由于斜裂缝出现后过早地开展,导致刚度退化,表现出来的延性较小。对于采用其它跨高比的连梁也或多或少地出现了一些问题。在文献[3]的试验中研究了跨高比为 1.0 的普通配筋连梁的受力性能,结果表明:如果按照传统的配筋方式,甚至增加成本去加大箍筋和水平腹筋用量,连梁仍发生明显的剪切破坏。文献[4]中的试验结果表明,跨高比较大的普通钢筋混凝土连梁在低周反复荷载作用下会发生较理想的弯曲破坏,相对延性比较好。所以,在高层建筑结构中想要寻找一种受力合理、便于施工而且延性较好的小跨高比连梁的结构型式。

其次,论文的研究内容。

本文的主要研究内容包括以下内容:

(1)本文首先对单个防屈曲支撑进行低周反复荷载试验,得出防屈曲支撑的屈服应变和抗震性能,为带防屈曲支撑钢连梁的试验提供依据;

(2)其次,本文对带防屈曲支撑钢连梁进行低周反复荷载试验,通过连梁的拟静力试验,了解连梁在反复荷载作用下的破坏机制,绘制出试件的荷载一位移滞回曲线及骨架曲线;从而分析这种结构的耗能能力、延性、强度和刚度退化情况;

(3)为了进一步深入研究,建立全楼层布置和只在层间位移角大的楼层布置带防屈曲支撑钢连梁联肢墙、普通钢筋混凝土连梁联肢墙、普通钢桁架连梁联肢墙框架-核心筒结构模型,并用动力弹塑性动时程分析在罕遇地震下对其进行分析,研究其抗震性能;

(4)对带防屈曲支撑钢连梁联肢墙进行施工上的分析,并与普通钢筋混凝土连梁联肢墙结构进行经济上的对比分析,为这种型式的工程应用提供依据。

最后,论文的不足之处。

但由于我自身所存在的知识储备方面的缺陷,使得文章中的相关观点还不够成熟,甚至可能存在错误观点的情形。对此,我热切希望能够得到各位老师的指导。让我在今后的学习中学到更多。谢谢!

第三篇:英文论文演讲稿

篇一:英语论文展示演讲稿

1、hello everyone!today i will introduce you a paper, which is called “effects of corporate governance on capital structure: empirical evidence from pakistan “

2、i will use the following four parts to introduce

3、i got this paper from the emerald reprints the world’s leading publisher of management research and the type of the paper is research paper 纳迪姆阿麦的sheke

4、then we can have a simple knowledge of the two authors:nadeem ahmed sheikh and 王宗军 one is a doctoral degree candidate in the school of management, hua zhong university of science and technology, wuhan.the other is a professor in this college 5.about the paper’s outline firstly the aim of this empirical study is to investigate whether corporate governance attributes affect capital structure choices of pakistani firms then the design of the paper is multiple regression analysis

6、in order to have a good knowledge of the paper we can from the following three aspects to the attributes of the corporate governance are background also includes :measures of corporate governance and their relation to capital structure

8、research design firstly 1.research methodology:it includes three aspects: data variables and methodology date: this study investigates the significant corporate governance attributes that may affect the capital structure of non-financial firms listed on the karachi stock exchange pakistan during 2004-2008.and the final sample set consists of 775 observations for 155 firms over a period of five years.this study employed panel data methodology(面板数据方式)because sample contained data across firms and over time

9、this table is the definition of variables.it includes three parts: 10.dependent variables consist of total debt ratio and long-term debt ratio.this is a basic formula.12、this table is the yearly mean value of shareholding pattern

13、here are some of regression analysis tables, through the multiple regression analysis the paper gives the conclusions

14、the results is as follows: capital structure is positively related to board size、outside directors and ownership concentration.that is to say: a large board serve as a means to obtain support from external environment;boards with more independent directors can take on more debt on favorable terms due to effective monitoring;block holders have more ability than dispersed shareholders to force management to take those actions that maximize the shareholder wealth.15、on the other hand, capital structure is negative related to managerial ownership、director remuneration、profitability and liquidity.16、in the end, i have a summary: the results of the paper indicate that corporate governance attributes, in part, explicate the financing behavior of pakistani firms and, the empirical results of this study provide support to corporate managers in establishing an optimal capital structure, and to regulatory authorities for enacting laws and developing institutional support to make corporate governance mechanisms work more effectively in the country.17、thats all, thank you for listen to me, if you are interested in this paper you can have a study after class thank you!篇二:英语论文演讲稿

my paper is revenge tragedy in english renaissance——about 《hamlet》 ppt1:....ppt2:....ppt3:....ppt4:next, let`s analyse the relationship between the characters in the drama.this is a relationship diagram.hamlet ,the prince of denmark and also the protagonist(主角、主要人物、领导者)was about thirty years old at the start of the play.hamlet is the son of queen gertrude and the late king hamlet, and the nephew of the present king, claudius.hamlet is melancholy, bitter, and cynical, full of hatred for his uncle’s scheming and disgust for his mother’s sexuality.a reflective and thoughtful young man who has studied at the university of wittenberg, hamlet is often indecisive and hesitant, but at other times prone to rash and impulsive acts.哈姆雷特 prince hamlet —— 丹麦王子。为父王的鬼魂所困扰,要对杀父凶手复仇。经历了痛苦的挣扎之后他达成了目的,整个王宫也陷入了死亡的恐怖之中。他最后也中了致命的毒剑死去。

claudius, as the king of denmark, hamlet’s uncle and the villain(反派角色)of the play, was a calculating, ambitious politician,and was driven by his sexual appetites and his lust for power, but he occasionally showed signs of guilt and human feeling—his love for gertrude, for instance, seems sincere.克劳迪斯 claudius —— 丹麦现任国王。他是哈姆雷特的叔父,在哥哥死后继任了王位。老国王的鬼魂告诉哈姆雷特,他正是谋杀自己的凶手。他罪有应得,最后死在侄子复仇的毒剑下。

鬼魂 king hamlet(ghost)—— 哈姆雷特的父亲死后化成的鬼魂。他被弟弟毒死时,哈姆雷特正在国外。

ophelia-polonius’s daughter, a beautiful young woman with whom hamlet has been in love.ophelia is a sweet and innocent young girl, who obeys her father and her brother, laertes.dependent on men to tell her how to behave, she gives in to polonius’s schemes(诡计)to spy(侦察)on hamlet.even in her lapse into(陷入)madness and death, she remains maiden, singing songs about flowers and finally drowning in the river。

欧菲莉 ophelia—— 波洛涅斯的女儿。她与哈姆雷特双双陷入爱河,但种种阻力警告王子,政治地位使他们无望结合。作为哈姆雷特疯狂复仇计划的一部分,她被他无情抛弃,加上父亲的死让她陷入精神错乱,最终失足落水溺毙。

ppt6: then let`s look at the character analysis of hamlet.hamlet pretended to be mad in order to revenge.he also use his intelligence to approve his uncle`s guilt.when hamlet confirmed that claudius was guilt, he decided to revenge without fear.then he also use stratagem to make himself avoid being killed.all of these approved that he was brave and smart.ppt7: he pursued ophelia and finally gave up because of the revenge.before he was fight with laertes, he said sorry to him.this indicates he was guilt and sorry for laertes because it was he that made laertes lose his father.these approved that he was a kind and sincere man.ppt8:.....ppt9: when we read the play, we can also easily feel the dilemma.just like the words “to be or not to be-that is the question” ppt10:.....ppt11:......篇三:如何写好英文演讲稿

如何写好英文演讲稿

从很多方面来说,写演讲稿就像写论文,但演讲稿却没有像论文那般特别注重单词的拼写与标点的错误。写演讲稿的时候,不要用一些发音不顺畅或是你不明白意思的单词,因为会导致你的演讲不够流畅。instructions 说明

1.assess how much time your speech should take.if you dont have a time limit, try to keep your speech brief yet informative.估算自己演讲所需的时间。如果没有演讲上的时间限制,就尽量让你的演讲篇幅简短且内容丰富。

2.think about your audience and let your perception of the audience shape the tone of your speech as you write it.站在听众的角度多想想,当你撰写演讲稿时,你要让观众也能在演讲稿中切身体会你的演讲魅力。

3.begin with an introduction that establishes who you are, what your purpose is, what youll be talking about and how long youre going to take.you may want to include a joke, anecdote or interesting fact to grab the audiences attention.先介绍自己,以表述演讲目的、演讲主题和演讲时长作为开端。在这段话中,你要说一个笑话、奇闻奇事或趣事来直接引起听众的注意。

4.organize your information into three to seven main points and prioritize them according to importance and effectiveness.用3-7条大纲组织演讲内容信息,并根据重要性和有效性分清要点主次。

5.delete points that arent crucial to your speech if you have too many for your time frame.假如时间不允许,你可以删减一些演讲中不重要的点。

6.start with your most important point, then go to your least important point and move slowly back toward the most important.for example, if you have five points with no.5 being the most important and no.1 being the least important, your presentation order would be 淘宝专业编制 id:文章团购网

5-1-2-3-4.从最重要的一点开始你的演讲,之后到次重要点,然后再慢慢回到最重要点上。例如,你的演讲稿中有5点要讲,第5点是其中的重中之重,而第1点是次重要点,你的演讲顺序应为:51234。7.add support to each point using statistics, facts, examples, anecdotes, quotations or other supporting material.借助图表、事实、例子、奇闻轶事、引文与其它材料作为演讲点的支撑部分。

8.link your introduction, points and conclusions together with smooth transitions.引言、演讲要点和结论连贯顺承地串在一起。
