learning to get along with our parents 。
Good morning, ladies and gentlemen Today my topic is“Learning to get along with our parents”
These days, most of us feel it is hard to get along with our parents We easily get angry for no reason and even talk to them for days
I think the causes are as follows First, our parents only care about our marks and it makes us stressed Second, we are unwilling to communicate with them
It's time for us to change First, we can communicate with them by sharing our joys and worries with them Then, we can help do some housework to show our love for them Finally, we should achieve a balance between our school work and hobbies so that they won't feel worried about us
That's all for my speech Thank you!

英语演讲比赛中一般以什么为主题比较好?
你可以谈一下你是则么学英语的,或者你现在的梦想或者是你曾经的梦想,,为什么他是曾经的什么的,或者你的业余生活,还有你的童年生活啊,你的兴趣爱好啊,讲一下你的原因。无论你讲什么,口语流利,不要拖拖拉拉就好了。现在我们每天都有一篇口语演讲。刚开始的话是不需要写太多从句的,你可以用最简单的句子,但是一定不能忘词。这是我的观点。
我要做一个英语演讲,以什么为主题比较好我建议’creativity创新力‘或者’sustainability可持续发展‘这都是现在世界很热的话题。比千篇一律的话题更能吸引人眼球。

急求英语演讲比赛作文 what cannot afford to lose,要以信念为主题What cannot afford to lose
Confidence, self-believe and faith are interlinked and the three important elements for everyone, and no one could do without In other words, we all should possess any one of them or all three of them in order to do well and be suessful in our life
There is no one can ever achieve things without any of the above three things Just imagine that when you have no confidence in yourself at all, what could you possibly in doing anything good Just imagine that when you have no self-believe at all, what could you possibly in doing anything right Just imagine that when you have no faith in youself at all, what could you possibly in doing anything correct
Therefore, possession of these three unmissable elements are a must for anyone and everyone Without them, you won't stand chance in sueeding anything at all They are what we cannot afford to lose!

现在国家的大学越来越大,招收的学生也越来越多,学校也越来越多,相应的学校活动也就增多。活动的增多也就预示着活动策划书也越来越多,但是策划书一般都有学生来书写,所以如何写活动策划书也就成了一个问题。
其实活动策划书并不是很难写,只要掌握了些策划书的方法,写策划书那真是手到擒来,只是方法的问题。
那么方法到底难写不,一点也不,只要你看完下面的方法,写活动策划书那就是轻而易举的事情了:
一、策划书名称
尽可能具体的写出策划名称,如“×年×月××大学××活动策划书”,置于页面中央,当然可以写出正标题后将此作为副标题写在下面。
二、 活动背景 :
这部分内容应根据策划书的特点在以下项目中选取内容重点阐述;具体项目有:基本情况简介、主要执行对象、近期状况、组织部门、活动开展原因、社会影响、以及相关目的动机。其次应说明问题的环境特征,主要考虑环境的内在优势、弱点、机会及威胁等因素,对其作好全面的分析,将内容重点放在环境分析的各项因素上,对过去现在的情况进行详细的描述,并通过对情况的预测制定计划。如环境不明,则应该通过调查研究等方式进行分析加以补充。
三、 活动目的、意义和目标:
活动的目的、意义应用简洁明了的语言将目的要点表述清楚;在陈述目的要点时,该活动的核心构成或策划的独到之处及由此产生的意义(经济效益、社会利益、媒体效应等)都应该明确写出。活动目标要具体化,并需要满足重要性、可行性、时效性。
四、资源需要:
列出所需人力资源,物力资源,包括使用的地方,如教室或使用活动中心都详细列出。可以列为已有资源和需要资源两部分。
五、活动开展:
作为策划的正文部分,表现方式要简洁明了,使人容易理解,但表述方面要力求详尽,写出每一点能设想到的东西,没有遗漏。在此部分中,不仅仅局限于用文字表述,也可适当加入统计图表等;对策划的各工作项目,应按照时间的先后顺序排列,绘制实施时间表有助于方案核查。人员的组织配置、活动对象、相应权责及时间地点也应在这部分加以说明,执行的应变程序也应该在这部分加以考虑。
这里可以提供一些参考方面:会场布置、接待室、嘉宾座次、赞助方式、合同协议、媒体支持、校园宣传、广告制作、主持、领导讲话、司仪、会场服务、电子背景、灯光、音响、摄像、信息联络、技术支持、秩序维持、衣着、指挥中心、现场气氛调节、接送车辆、活动后清理人员、合影、餐饮招待、后续联络等。请根据实情自行调节。
六、经费预算:
活动的各项费用在根据实际情况进行具体、周密的计算后,用清晰明了的形式列出。
七、活动中应注意的问题及细节:
内外环境的变化,不可避免的会给方案的执行带来一些不确定性因素,因此,当环境变化时是否有应变措施,损失的概率是多少,造成的损失多大,应急措施等也应在策划中加以说明。
八、活动负责人及主要参与者:
注组织者、参与者姓名、嘉宾、单位(如果是小组策划应注明小组名称、负责人)。
注意:
1、 本策划书提供基本参考方面,小型策划书可以直接填充;大型策划书可以不拘泥于表格,自行设计,力求内容详尽、页面美观;
2、 可以专门给策划书制作封页,力求简单,凝重;策划书可以进行包装,如用设计的徽标做页眉,图文并茂等;
3、 如有附件可以附于策划书后面,也可单独装订;
4、 策划书需从纸张的长边装订;
5、 一个大策划书,可以有若干子策划书。
上面就是怎么写活动策划书的,如果你按照上面的格式和方法来写,那么你的策划书写的一定是十拿九稳的事情,这你要放心,只是你态度问题。
大学活动策划书,只要有机会就可以多写几份,毕竟这是一次很锻炼人的机会,在你工作后你会有很多的策划书要写,现在写好了,将来害怕写策划书吗。
所以说让自己忙碌一些,多学点东西,对任何人是没有任何坏处的。
演讲稿 是进行演讲的依据,也是对演讲内容和形式的规范和提示。演讲稿可以用来交流思想和感情,表达主张和见解。以下是我精心收集整理的 校园英语主题大赛演讲5篇 ,下面我就和大家分享,来欣赏一下吧。
校园英语主题大赛演讲1
Ladies and Gentlemen, Good afternoon!
I’m very glad to stand here and give you a short speech Today my topic is “youth” I hope you will like it, and found the importance in your youth so that more cherish it
First I want to ask you some questions:
1、Do you know what is youth 2、How do you master your youth
Youth
Youth is not a time of life, it is a state of mind; it is not rosy cheeks , red lips and supple knees, it is a matter of the emotions : it is the freshness ; it is the freshness of the deep springs of life
Youth means a temperamental predominance of courage over timidity of the appetite, for adventure over the love of ease This often exists in a man of 60 more than a boy of 20 Nobody grows old merely by a number of years We grow old by deserting our ideals
Years wrinkle the skin, but to give up enthusiasm wrinkles the soul Worry, fear, self –distrust bows the heart and turns the spirit back to dust
Whether 60 of 16, there is in every human being ‘s heart the lure of wonders, the unfailing childlike appetite of what’s next and the joy of the game of living In the center of your heart and my heart there’s a wireless station: so long as it receives messages of beauty, hope ,cheer, courage and power from men and from the infinite, so long as you are young
When the aerials are down, and your spirit is covered with snows of cynicism and the ice of pessimism, then you are grown old ,even at 20 , but as long as your aerials are up ,to catch waves of optimism , there is hope you may die young at 80
Thank you!
校园英语主题大赛演讲2
Today I am very glad to be here to share with you my ideas of success What is success It is what everyone is longing forSometimes success would be rather simple Winning a game is success; getting a high grade in the exam is success; making a new friend is success; even now I amstanding here giving my speech is somehow also success
However, as a person’s whole life is concerned, success becomes very complicated Is fortune success Is fame success Is high social status success No, I don’t think so I believe success is the realization of people’s hopes and idealsNowadays, in the modern society there are many peoplewho are regarded as the successful And the most obvious characteristics of hem are money, high position and luxurious life So most people believe that s success and all that they do is for this purpose But the problem is wether it is real success
We all know there are always more money, higher position and better condition in front of us If we keep chasing them, where is the end What will satisfy us at last Therefore, we can see, to get the real Success we must need something inside, which is the realization of people’ hopes and ideals
Different people have different ideas about success; cause people’s hopes and ideas vary from one another But I am sure every success is dear to everybody, cause it is not easy to come by, cause in the process of our striving for success, we got both our body and soul tempted, meanwhile we are enlightened by the most valuable qualities of human beings: love, patient, courage and sense of responsibility These are the best treasures So now I am very proud that I have this opportunity to stand here speaking to all of you It is my success, cause I raise up to challenge my hope
What is success Everyone has his own interpretation as I do But I am sure every success leads to an ever-brighter future So ladies and gentlemen, believe in our hopes, believe in ourselves, we, every one of us, can make a successful life! Wish you all good success!
校园英语主题大赛演讲3
Honorable Judges, fellow students:
Good afternoon!
Recently, ther is a heated debate in our society The college students are the beneficiaries of a rare privilege, who receive exceptional education at extraordinary places But will we be able to face the challenge and support ourselves against all odds Will we be able to better the lives of others Will we be able to accept the responsibility of building the future of our country
The cynics say the college students are the pampered lost generation, which would cringe at the slightest discomfort But the cynics are wrong The college students I see are eagerly learning about how to live independently We help each other clean the dormitory, go shopping and bargain together, and take part time jobs to supplement our pocket money
The cynics say we care for nothing other than grades; and we neglect the need for character cultivation But again, the cynics are wrong We care deeply for each other, we cherish freedom, we treasure justice, and we seek truth Last week, thousands of my fellow students had their blood type tested in order to make a contribution for the children who suffer from blood cancer
As college students, we are adolescents at the critical turning point in our lives We all face a fundamental choice: cynicism or faith, each will profoundly impact our future, or even the future of our country I believe in all my fellow classmates Though we are still inexperienced and even a little bit childish I believe that we have the courage and faith to meet any challenge and take on our responsibilities We are preparing to assume new responsibilities and tasks, and to use the education we have received to make our world a better place I believe in our future
thank you!

good morning/evening/afternoon, ladies and gentlemen :
today, my speech is about talents,in my opionion, talents are indispensable in nowadays society as is known to all that the fight among countries is actually the fight among talents
first, i'd like to define the word"talent" in my idea, a talent is one person who is good at or expertised in some or multiple areas nowadays, as the world developing goes on , if one country want to rank top or do a good job in the world, the country must have many example, china, the biggest developing country in the world, in the past 100 years, is always invaded by other countries, why ,the reason is that china at that time had not so many talents if they had anti-intrusion leader talents in the war, needleto say,they would have beat those big they had talents in weapons manufacturing, nodody dares to provoke ver, nowadays, it's a totally different situation, china has become powerfulin all over the world, why because there are many talents serving the country, the civilians become more and more and more people go to university,more and more people come to receive further education so what is that in return,talents in army protect our country from invasion, talents in commerce help make our economy keep in improving, talents
in aerospace make the world see chinese manned spacecraft flying talents in sports make china rank the first in the olympic games
to sum up, talents will play a more and more impoetant role in the world, if one country intends to flourish, he must foster talents as many as they can ,that's all。
thank you!

but father made this all different!he works very hard on his own business, now we have our own 2 housese,surly,i have my own roomand he take our family so much happiness, richer and richer
when i was little, i did everything with my dad you could always find me sitting on his knee or walking and doing everything with him every night he would read me a bed time story and make the voices of each character
i learnt a lot from my daddy i learnt to never take things to seriously and to always smile
like many other fathers, my dad and i also has generation gap he is not good at or even can’t work the computer so when i sitting at the computer desk,he will say something like ‘you should pay more attention to your study’, ‘don’t waste time on the computer games’ , ‘it will be bad for your eyes’ and so on how can i- a computer fan – reduce time on computer so i continue studying and playing on it
years pasted, my father is over 45 now it is time for me to look after him and i am sure i will do and we will live an even better life and i will say,i really love you dad,cause you are the hero in my mind
thank you so much!

核能的利用
核能俗称原子能,它是指原子核里的核子(中子或质子)重新分配和组合时释放出来的能量。核能分为两类,一类叫核裂变能,它是指重元素(铀或钚等)的原子核发生裂变时释放出来的能量。另一类叫聚变能,它是指轻元素(氘和氚)的原子核在发生聚变反应时释放出来的能量。
核能有巨大的威力,1公斤铀原子核全部裂变释放出的能量,约等于2700吨标准煤燃烧时所放出的化学能。一座100万千瓦的核电站,每年只需25~30吨低浓度铀核燃料,而相同功率的煤电站,每年则需要有300多万吨原煤,这些核燃料只需10辆卡车就能运到现场,而运输300多万吨煤炭,则需要1000列火车。核聚变反应释放的能量更可贵。有人作过生动的比喻:1公斤煤只能使一列火车开动8米,1公斤铀可使一列火车开动4万公里;而1公斤氚化锂和氘比锂的混合物,可使一列火车从地球开到月球,行程40万公里。地球上蕴藏着数量可观的铀、钍等核裂变资源,如果把它们的裂变能充分地利用起来,可满足人类上千年的能源需求。在汪洋大海里,蕴藏着二十万亿吨氘,它们的聚变能可顶几万亿亿吨煤,可满足人类百亿年的能源需求。
核能是人类最终解决能源问题的希望。核能技术的开发,对现代社会会产生深远的影响。
核裂变能
核能的成就虽然首先被应用于军事目的,但其后就实现了核能的和平利用,其中最重要也是最主要的是通过核电站来发电。
核电站已跻身电力工业行列,是利用原子核裂变反应放出的核能来发电的装置,通过核反应堆实现核能与热能的转换。核反应堆的种类,按引起裂变的中子能量分为热中子反应堆和快中子反应堆。由于热中子更容易引起铀235的裂变,因此热中子反应堆比较容易控制,大量运行的就是这种热中子反应堆。这种反应堆需用慢化剂,通过它的原子核与快中子d性碰撞,将快中子慢化成热中子。早在本世纪50年代初,人类开始开发利用核能,诞生了核电站。经过30多年的发展,核电已是世界公认的经济实惠、安全可靠的能源。
截至1993年12月31日,全世界已有34个国家或地区的422座(堆)核电站正在运行,总装机容量为356235亿千瓦;正在建造的核电站有61座(堆),总装机容量为55866万千瓦。全世界1993年全年核发电总量为21817679GWh,核发电量占世界总发电量的17%以上。世界核电厂一览表见下表。

核能是能源的重要发展方向,特别在世界能源结构从石油为主向非油能源过渡的时期,核能、煤炭和节能被认为是解决能源危机的主要希望。为此,各国都在大力发展核电。然而特别令人担心的是,根据目前探明的有经济开采价值的铀矿储量,如果继续按现有速度建造眼下的热中子堆核电站,由于它只能利用铀资源的1%~2%,则要不了50年,经济可采的铀矿也会耗尽。如果到那时,还不能脱离核裂变能利用的初级阶段,人类将可能面临新的能源危机。
在能源新挑战面前,核科学家早已在寻找应战的武器,这就是已经过40多年研究开发的快中子增殖堆(简称快堆)核电站。有了它,相当于把铀资源的利用率提高了50~60倍,那样能源的供应将出现新的奇迹,在今后上千年内,人类完全可以靠快堆发电,保证有富足的能源可用。
快堆的最显著的特点是直接靠核裂变产生的快速飞行的中子来维持链式裂变反应。它以钚-239作燃料,“炉膛”里不设慢化剂,只有冷却剂(钠或氦)。在快堆中,每“烧掉”一个钚-239原子,能够使铀-238吸收中子后新生产出14个钚-239原子,这样在快堆中就出现了神话般的奇迹——核燃料越“烧”越多。这就是所谓的核燃料的增殖过程。
快堆开动起来之后,会不断地有铀-238吸收中子变成钚-239,经过一段时间后(例如15~20年),人们可以队“烧”过的核燃料“灰烬”中,提取出足以装备与自身功率一样大的新堆所需要的钚燃料,在此期间,快堆电站只要继续添加热堆中不能作燃料的铀-238贫料,而所得的电能却比热堆核电站还要多。人们把快堆誉为能发电的“核燃料生产厂”。
快堆实际上是核电站家族中资格最老的成员。早在1951年8月,美国建成了世界上第一座实验快堆,而且成功地作了发电试验。虽然当时它的电功率只有200千瓦。可它却是世界上最先问世的快堆核电站。
30多年来,一些工业发达的国家(如美、英、法、前苏联、日本和德国),投入大量人力、物力,耗资几十亿美元来发展快堆。目前,全世界总共有21座快堆。其中在运行的有13座,正在建造的有4座,计划建造的有7座。原型快堆已经成功地运行了十年多,已经证明快堆在技术上是可以实现的,增殖核燃料也是可能的(凤凰快堆的增殖比为1:15)。现在电功率为120万千瓦的大型商业验证快堆正在法国运行。快堆技术已经走出了实验室的大门,正走向工业化应用的康庄大道。
各国普遍认为,快堆是发电堆的最终归宿,特别是在受控核聚变难以在今后相当长时期内工业推广的情况下,快堆发电更是重要。但需要指出的是,快堆技术至今尚未成熟,重要原因是快堆技术本身要比热堆复杂得多,尚有不少技术关键问题需要攻克。此外,快堆的建造费用要比热堆大得多,现在快堆的造价要比同规模的热堆贵2~3倍。有人估计,当快堆的单堆功率超过200万千瓦时,经济上可能与热堆媲美。预计到下世纪初,人们一定能建造出这样的大型快堆,那时快堆电站将会在全世界推广应用。发展快堆进展最快的法国,计划从下世纪初开始,推广快堆电站工业,因此天然铀的需要量将逐步下降,从而减轻了进口能源所造成的压力。快堆必将是从热堆核电站向核聚变电站过渡的桥梁。
核聚变能
人类将最终解决能源需求的希望,寄托在受控核聚变的实现和推广上。核聚变能是利用轻原子核(如氘-氘或氘-氚)在极高温度(几千万度或上亿度)下聚合成较重的原子核(如氦)过程中释放出来的巨大的能量。核聚变的主要燃料是氘,可以比较容易地从海水中提取到。据推算,每升海水中所含的氘若完全“燃烧”,可产生相当于300升汽油的能量。海水中至少含有35万亿吨氘,可以供全世界享用百亿年以上。更为可贵的是核聚变反应中几乎不存在放射性污染,而且核聚变反应堆在任何时刻都只有一丁点的氘在聚变,所以不存在失控所带来的危险。聚变能是名符其实的理想、干净的能源。但是,要使核聚变能顺从地在人为控制下为人类服务却是一件十分困难的事。为了驯服核聚变能,从50年代初开始,科学家们就热心地进行受控核聚变的研究。
全世界已有40多个国家在进行受控核聚变的研究,它们投入了大量人力和物力,建造了几百个实验装置,从事研究的科学人员约有12000多人。目前,全世界每年用于核聚变研究的费用已超过20亿美元。
经过几十年的艰苦努力,受控核聚变为什么进展如此缓慢呢?主要是因为实现受控核聚变的条件非常苛刻。首先,我们无法同时造成太阳中心那样高的等离子体密度和极高的温度,只有追求比太阳中心更高的温度来解决问题。理论研究表明,氘核的聚变点火温度达四亿摄氏度,氘氚混合气体的热核反应也要在五千万摄氏度才能进行。要创造这样的环境在技术上是困难重重的。随着新技术的开发利用,人们试用电流、激光等方法来加热气体。其次,还要使这样高的温度保持一段时间,等离子体温度越低,数量越少,密度越小,超高温保持时间就越要长。还有,超高温的等离子体,有强烈地向外扩张的特性,必须有极强的磁场来约束住它们,绝对不让它们与四周容器壁接触,否则任何材料也挡不住如此高的温度,顷刻气化,变为乌有。要解决这些重重困难,有待于激光技术、超导技术、新材料技术等崭新技术的飞跃发展。
科学技术的进步,不断地给受控核聚变的研究带来福音,经过了漫长的接力赛跑之后,受控核聚变的研究已经到了关键的时刻。1982年12月24日,美国建成了一座有三层楼高的“托卡马克型”核聚变实验反应堆(TFTR),从设计到建成这座核聚变实验堆总共花了七年时间,耗资3亿多美元。设计这座反应堆的目的是为了实现输出能量等于输入能量,以便证明实现受控核聚变的可能性。
我国进行可控核聚变的研究也已多年,并取得一定的进展。我国建有近十个小型托卡马克受控核聚变试验装置,其中最大的是“中国环流器一号”,已于1984年9月建成,并顺利启动。经过一年多的调试,已于1985年11月16日通过国家验收,它为我国核聚变能的研究和等离子体技术的发展,提供了有效的手段。
现在,美、英、俄等国正在共同建设一座博采众长的国际核聚变反应堆,这种国际核聚变堆将采纳30年来全世界核聚变研究的成果。它的设计输出热功率为62万千瓦,真空室半径为520厘米,等离子体磁约束环形半径为130厘米,比美国新建的核聚变实验堆规模要大一倍。各国科学家寄希望于这座核聚变堆在受控核聚变攻关中实现质的飞跃。最重要的是,要求在聚变反应中得到的能量超过输入能量,从而证明实现受控核聚变发电在技术上和工程上是可行的。
当然,人类要真正用上廉价的聚变能,尚需经过艰苦的奋斗,经受时间的考验。有人估计,到2020年可以建成实证堆,然后,经过工程技术和经济上的验证,才能逐步地推向商用。总之,在能源革命中占有重要地位的核聚变能开发和利用的曙光已在前头。
