为您找到与英文演讲的注意事项相关的共54个结果:
您的外语怎么样学的?怎么样才能将自己的所学准确生动的表达,运用到演讲里去?
段津:学习也没有什么捷径可走。
1,慢慢积累,不要放弃。基础一定要打好,特别是语法的基础。我在学校学的时间不长,但是基础非常稳固。光介词的练习就不知道做了几百几千,冠词的练习,什么时候用THE,什么时候不用,这些基础都非常牢固;
2,多看、多读、多模仿。英语开始就是模仿,注意外国人的表达方法。我当时在外交学会上班时有机会接触美国、澳大利亚、加拿大、新西兰广大地区的各阶层人士。另一方面我非常注意阅读。当时美国的四本周刊我都看,《新闻周刊》、《时代》等等,而且是越看不明白的东西越看;
3,要记录。写有用的短语、词句,要把它记下来,而且要注意比较外国人和中国不同的表达法。举个例子,中国人讲话的时候,谢谢大家对我的热烈欢迎,很平实的。英语国家的人讲这么一句话,“Thank you for the warm hospitality that makes me feel so welcome。”意思就是“谢谢你们的好客,这个好客使我感觉到自己如此受欢迎”。假如你没有看过英文、听过英文,你绝对不能想到这么表达。所以你就要学,就要听。我们不能说我学的时候学了,自己讲得时候还照中文讲,不能这样,要用英文来思维,越是觉得有点怪怪的,越是要学的。时间久而久之,你就不会讲中式英文。
在被邀请演讲但又不很清楚对方的具体要求时如何进行?内容上什么样的安排会收到好的效果?
段津:这种情况我会首先要进行调查研究。是谁邀请的,邀请我去跟谁讲,再根据听众的特点,自己做一个估计。
比如说我在澳大利亚时,收到一个请帖,就是澳大利亚悉尼大学。他们学生毕业典礼一千多人,让我作为唯一的外国嘉宾讲话。我的听众都是大学生、大学教授,18岁到20多岁。然后我再打电话给他们学校的组织讲演的校方询问他们希望我讲些什么东西,他给我的答复是随便,但是时间控制在10分钟。这样的话,我就有了几个信息:一个是他为什么不请美国人,请中国人,说明他对中国感兴趣。所以我根本上可以确定,我要讲讲中国的事情。中国情况;另一个是年轻学生加教授;再一个就是时间要短一点儿。这个场合是一个毕业典礼,根据这四个特点,我就准备出了一个讲稿。
具体进行的过程大概是这样的。我记得有一个英国作家讲过,你可以试一下谈别人,比如说你跟人家谈话时,你讲他的事情,他听两个小时都不腻,所以既要讲自己,也要讲别人。根据这样一个原则,我就在这个讲稿里头采取一种对比的办法。
我一上来就是澳大利亚和中国差别很大,共同点也很多,夏天我们都出汗,冬天我们都会冻得发抖,你吃饭用刀叉,我吃饭用筷子。比如说我们中国看问题是大中小,写地址是先写国名,再写省,再写城市,再写街道,再写门牌号,然后再写姓,然后写名。外国人先写名,再写姓,你的门牌号码、楼的号码、马路、城市、省份,最后是国家。整个是大颠倒。你们是由我及人,我们是由远及近。通过这些文化的对比,政治制度的对比。比如你们是议会民主,我们是半殖民地半封建的基础上建立起来的人民民主的国家,这个场合就避免人民民主专政,因为几句话讲不清楚。从文化、政治、经济对比。再就是物产,中国有多少动物、多少植物。一下子跳跃性的,一对比,共同点我们都希望和平,都希望过好日子。我们两国关系好了,对我们两国人民有什么好处。
最后,毕竟是青年学生,我引用了毛主席的一首诗,毛主席在50年代莫斯科对中国留学生讲的一段话,世界上是你们的,也是我们的,但归根结底是你们的,你们年轻人朝气蓬勃,正在兴旺时期,希望寄托在你们身上。这个话一讲,达到高潮,他们喜欢听。用伟大导师的话来打动他们。我是稿子念下来。关键是内容,内容好的话,语音语调也好,这样下来以后,那些小家伙戴着博士帽,拉着我一块照相,气氛非常热烈。

奥巴马关于开学的演讲稿是十分值得仔细阅读的。下面是由读文网小编整理的 奥巴马开学演讲中英文版,希望对大家有所帮助。
Hello, everybody! Thank you. Thank you. Thank you, everybody. All right, everybody go ahead and have a seat. How is everybody doing today? (Applause.) How about Tim Spicer? (Applause.) I am here with students at Wakefield High School in Arlington, Virginia. And we've got students tuning in from all across America, from kindergarten through 12th grade. And I am just so glad that all could join us today. And I want to thank Wakefield for being such an outstanding host. Give yourselves a big round of applause. (Applause.)
I know that for many of you, today is the first day of school. And for those of you in kindergarten, or starting middle or high school, it's your first day in a new school, so it's understandable if you're a little nervous. I imagine there are some seniors out there who are feeling pretty good right now -- (applause) -- with just one more year to go. And no matter what grade you're in, some of you are probably wishing it were still summer and you could've stayed in bed just a little bit longer this morning.
I know that feeling. When I was young, my family lived overseas. I lived in Indonesia for a few years. And my mother, she didn't have the money to send me where all the American kids went to school, but she thought it was important for me to keep up with an American education. So she decided to teach me extra lessons herself, Monday through Friday. But because she had to go to work, the only time she could do it was at 4:30 in the morning.
Now, as you might imagine, I wasn't too happy about getting up that early. And a lot of times, I'd fall asleep right there at the kitchen table. But whenever I'd complain, my mother would just give me one of those looks and she'd say, "This is no picnic for me either, buster." (Laughter.)
So I know that some of you are still adjusting to being back at school. But I'm here today because I have something important to discuss with you. I'm here because I want to talk with you about your education and what's expected of all of you in this new school year.
Now, I've given a lot of speeches about education. And I've talked about responsibility a lot.
I've talked about teachers' responsibility for inspiring students and pushing you to learn.
I've talked about your parents' responsibility for making sure you stay on track, and you get your homework done, and don't spend every waking hour in front of the TV or with the Xbox.
I've talked a lot about your government's responsibility for setting high standards, and supporting teachers and principals, and turning around schools that aren't working, where students aren't getting the opportunities that they deserve.
But at the end of the day, we can have the most dedicated teachers, the most supportive parents, the best schools in the world -- and none of it will make a difference, none of it will matter unless all of you fulfill your responsibilities, unless you show up to those schools, unless you pay attention to those teachers, unless you listen to your parents and grandparents and other adults and put in the hard work it takes to succeed. That's what I want to focus on today: the responsibility each of you has for your education.
I want to start with the responsibility you have to yourself. Every single one of you has something that you're good at. Every single one of you has something to offer. And you have a responsibility to yourself to discover what that is. That's the opportunity an education can provide.
Maybe you could be a great writer -- maybe even good enough to write a book or articles in a newspaper -- but you might not know it until you write that English paper -- that English class paper that's assigned to you. Maybe you could be an innovator or an inventor -- maybe even good enough to come up with the next iPhone or the new medicine or vaccine -- but you might not know it until you do your project for your science class. Maybe you could be a mayor or a senator or a Supreme Court justice -- but you might not know that until you join student government or the debate team.
And no matter what you want to do with your life, I guarantee that you'll need an education to do it. You want to be a doctor, or a teacher, or a police officer? You want to be a nurse or an architect, a lawyer or a member of our military? You're going to need a good education for every single one of those careers. You cannot drop out of school and just drop into a good job. You've got to train for it and work for it and learn for it.
And this isn't just important for your own life and your own future. What you make of your education will decide nothing less than the future of this country. The future of America depends on you. What you're learning in school today will determine whether we as a nation can meet our greatest challenges in the future.
You'll need the knowledge and problem-solving skills you learn in science and math to cure diseases like cancer and AIDS, and to develop new energy technologies and protect our environment. You'll need the insights and critical-thinking skills you gain in history and social studies to fight poverty and homelessness, crime and discrimination, and make our nation more fair and more free. You'll need the creativity and ingenuity you develop in all your classes to build new companies that will create new jobs and boost our economy.
We need every single one of you to develop your talents and your skills and your intellect so you can help us old folks solve our most difficult problems. If you don't do that -- if you quit on school -- you're not just quitting on yourself, you're quitting on your country.
Now, I know it's not always easy to do well in school. I know a lot of you have challenges in your lives right now that can make it hard to focus on your schoolwork.
I get it. I know what it's like. My father left my family when I was two years old, and I was raised by a single mom who had to work and who struggled at times to pay the bills and wasn't always able to give us the things that other kids had. There were times when I missed having a father in my life. There were times when I was lonely and I felt like I didn't fit in.
So I wasn't always as focused as I should have been on school, and I did some things I'm not proud of, and I got in more trouble than I should have. And my life could have easily taken a turn for the worse.
But I was -- I was lucky. I got a lot of second chances, and I had the opportunity to go to college and law school and follow my dreams. My wife, our First Lady Michelle Obama, she has a similar story. Neither of her parents had gone to college, and they didn't have a lot of money. But they worked hard, and she worked hard, so that she could go to the best schools in this country.
Some of you might not have those advantages. Maybe you don't have adults in your life who give you the support that you need. Maybe someone in your family has lost their job and there's not enough money to go around. Maybe you live in a neighborhood where you don't feel safe, or have friends who are pressuring you to do things you know aren't right.
But at the end of the day, the circumstances of your life -- what you look like, where you come from, how much money you have, what you've got going on at home -- none of that is an excuse for neglecting your homework or having a bad attitude in school. That's no excuse for talking back to your teacher, or cutting class, or dropping out of school. There is no excuse for not trying.
Where you are right now doesn't have to determine where you'll end up. No one's written your destiny for you, because here in America, you write your own destiny. You make your own future.
That's what young people like you are doing every day, all across America.
Young people like Jazmin Perez, from Roma, Texas. Jazmin didn't speak English when she first started school. Neither of her parents had gone to college. But she worked hard, earned good grades, and got a scholarship to Brown University -- is now in graduate school, studying public health, on her way to becoming Dr. Jazmin Perez.
I'm thinking about Andoni Schultz, from Los Altos, California, who's fought brain cancer since he was three. He's had to endure all sorts of treatments and surgeries, one of which affected his memory, so it took him much longer -- hundreds of extra hours -- to do his schoolwork. But he never fell behind. He's headed to college this fall.
And then there's Shantell Steve, from my hometown of Chicago, Illinois. Even when bouncing from foster home to foster home in the toughest neighborhoods in the city, she managed to get a job at a local health care center, start a program to keep young people out of gangs, and she's on track to graduate high school with honors and go on to college. And Jazmin, Andoni, and Shantell aren't any different from any of you. They face challenges in their lives just like you do. In some cases they've got it a lot worse off than many of you. But they refused to give up. They chose to take responsibility for their lives, for their education, and set goals for themselves. And I expect all of you to do the same.
That's why today I'm calling on each of you to set your own goals for your education -- and do everything you can to meet them. Your goal can be something as simple as doing all your homework, paying attention in class, or spending some time each day reading a book. Maybe you'll decide to get involved in an extracurricular activity, or volunteer in your community. Maybe you'll decide to stand up for kids who are being teased or bullied because of who they are or how they look, because you believe, like I do, that all young people deserve a safe environment to study and learn. Maybe you'll decide to take better care of yourself so you can be more ready to learn. And along those lines, by the way, I hope all of you are washing your hands a lot, and that you stay home from school when you don't feel well, so we can keep people from getting the flu this fall and winter.
But whatever you resolve to do, I want you to commit to it. I want you to really work at it. I know that sometimes you get that sense from TV that you can be rich and successful without any hard work -- that your ticket to success is through rapping or basketball or being a reality TV star. Chances are you're not going to be any of those things.
The truth is, being successful is hard. You won't love every subject that you study. You won't click with every teacher that you have. Not every homework assignment will seem completely relevant to your life right at this minute. And you won't necessarily succeed at everything the first time you try.
That's okay. Some of the most successful people in the world are the ones who've had the most failures. J.K. Rowling's -- who wrote Harry Potter -- her first Harry Potter book was rejected 12 times before it was finally published. Michael Jordan was cut from his high school basketball team. He lost hundreds of games and missed thousands of shots during his career. But he once said, "I have failed over and over and over again in my life. And that's why I succeed."
These people succeeded because they understood that you can't let your failures define you -- you have to let your failures teach you. You have to let them show you what to do differently the next time. So if you get into trouble, that doesn't mean you're a troublemaker, it means you need to try harder to act right. If you get a bad grade, that doesn't mean you're stupid, it just means you need to spend more time studying.
No one's born being good at all things. You become good at things through hard work. You're not a varsity athlete the first time you play a new sport. You don't hit every note the first time you sing a song. You've got to practice. The same principle applies to your schoolwork. You might have to do a math problem a few times before you get it right. You might have to read something a few times before you understand it. You definitely have to do a few drafts of a paper before it's good enough to hand in.
Don't be afraid to ask questions. Don't be afraid to ask for help when you need it. I do that every day. Asking for help isn't a sign of weakness, it's a sign of strength because it shows you have the courage to admit when you don't know something, and that then allows you to learn something new. So find an adult that you trust -- a parent, a grandparent or teacher, a coach or a counselor -- and ask them to help you stay on track to meet your goals.
And even when you're struggling, even when you're discouraged, and you feel like other people have given up on you, don't ever give up on yourself, because when you give up on yourself, you give up on your country.
The story of America isn't about people who quit when things got tough. It's about people who kept going, who tried harder, who loved their country too much to do anything less than their best.
It's the story of students who sat where you sit 250 years ago, and went on to wage a revolution and they founded this nation. Young people. Students who sat where you sit 75 years ago who overcame a Depression and won a world war; who fought for civil rights and put a man on the moon. Students who sat where you sit 20 years ago who founded Google and Twitter and Facebook and changed the way we communicate with each other.
So today, I want to ask all of you, what's your contribution going to be? What problems are you going to solve? What discoveries will you make? What will a President who comes here in 20 or 50 or 100 years say about what all of you did for this country?
Now, your families, your teachers, and I are doing everything we can to make sure you have the education you need to answer these questions. I'm working hard to fix up your classrooms and get you the books and the equipment and the computers you need to learn. But you've got to do your part, too. So I expect all of you to get serious this year. I expect you to put your best effort into everything you do. I expect great things from each of you. So don't let us down. Don't let your family down or your country down. Most of all, don't let yourself down. Make us all proud.
Thank you very much, everybody. God bless you. God bless America. Thank you.

学好初一的地理需要注意些什么呢?接下来是读文网小编为大家带来的学好初一地理的五个注意事项,供大家参考。
1、学会使用课本
教科书是培养自学能力的最好工具。目录提示着全书的要领和前后的联系,要经常翻阅,以便对全书内容心中有数。精读课文、深思要点,记下问题。,要特别重视插图和表格,领会图表所说明的问题。
2、学会使用地图
地图是地理信息的载体,又是学习地理的工具,通过分析地图,可以认识地理特征、原理、成因,找到利用改造的途径,要学会读、用各种地图,首先要记住最基本的地图。
3、重视地理观察
观察就是边思考边细看。看一看当地的地理环境的面貌,以及人们在当地是怎样活动的。通过报刊、电视节目、图片获得地理信息,可以锻炼我们的才智。
4、善于地理想象
“观察只能得到局部直观,地图只能提供位置直观,想象才能使二者联系起来,从而才能获得地理环境的全面景观。”
5、要善于动脑
地理问题的一般思路是:①学什么?如黄河及其水文特征。②在哪里?如黄河流经的省区和流域范围。③为什么?如黄河的水文特征是怎样形成的。④有何利弊?如怎样评价黄河对我国北部地区提供的有利条件和不利条件。⑤怎样协调好人地关系?如怎样使人类与黄河的关系协调起来,应当怎样合理利用改造它。

高考化学答题技巧及注意事项总结免费
关于高考化学科目的考试时,大家要注意在书写化学专有名词时一定不要写错别字。以下是小编准备的一些高考化学答题技巧及注意事项总结,仅供参考。
1.元素或物质推断类试题
该类题主要以元素周期律、元素周期表知识或物质之间的转化关系为命题点,采用提供周期表、文字描述元素性质或框图转化的形式来展现题干,然后设计一系列书写化学用语、离子半径大小比较、金属性或非金属性强弱判断、溶液中离子浓度大小判断及相关简单计算等问题。此类推断题的完整形式是:推断元素或物质、写用语、判性质。
【答题策略】
元素推断题,一般可先在草稿纸上画出只含短周期元素的周期表,然后对照此表进行推断。
(1)对有突破口的元素推断题,可利用题目暗示的突破口,联系其他条件,顺藤摸瓜,各个击破,推出结论;
(2)对无明显突破口的元素推断题,可利用题示条件的限定,逐渐缩小推求范围,并充分考虑各元素的相互关系予以推断;
(3)有时限定条件不足,则可进行讨论,得出合理结论,有时答案不止一组,只要能合理解释都可以。若题目只要求一组结论,则选择自己最熟悉、最有把握的。有时需要运用直觉,大胆尝试、假设,再根据题给条件进行验证也可。
无机框图推断题解题的一般思路和方法:读图审题→找准“突破口”→逻辑推理→检验验证→规范答题。解答的关键是迅速找到突破口,一般从物质特殊的颜色、特殊性质或结构、特殊反应、特殊转化关系、特殊反应条件等角度思考。突破口不易寻找时,也可从常见的物质中进行大胆猜测,然后代入验证即可,尽量避免从不太熟悉的物质或教材上没有出现过的物质角度考虑,盲目验证。
2.化学反应原理类试题
该类题主要把热化学、电化学、化学反应速率及三大平衡知识融合在一起命题,有时有图像或图表形式,重点考查热化学(或离子、电极)方程式的书写、离子浓度大小比较、反应速率大小、平衡常数及转化率的计算、电化学装置、平衡曲线的识别与绘制等。设问较多,考查的内容也就较多,导致思维转换角度较大。试题的难度较大,对思维能力的要求较高。
【答题策略】
该类题尽管设问较多,考查内容较多,但都是《考试大纲》要求的内容,不会出现偏、怪、难的问题,因此要充满信心,分析时要冷静,不能急于求成。这类试题考查的内容很基础,陌生度也不大,所以复习时一定要重视盖斯定律的应用与热化学方程式的书写技巧及注意事项;有关各类平衡移动的判断、常数的表达式、影响因素及相关计算;影响速率的因素及有关计算的关系式;电化学中两极的判断、离子移动方向、离子放电先后顺序、电极反应式的书写及有关利用电子守恒的计算;电离程度、水解程度的强弱判断及离子浓度大小比较技巧等基础知识,都是平时复习时应特别注意的重点。在理解这些原理或实质时,也可以借用图表来直观理解,同时也有利于提高自己分析图表的能力与技巧。总结思维的技巧和方法,答题时注意规范细致。再者是该类题的问题设计一般没有递进性,故答题时可跳跃式解答,千万不能放弃。
3.实验类试题
该类题主要以化工流程或实验装置图为载体,以考查实验设计、探究与实验分析能力为主,同时涉及基本操作、基本实验方法、装置与仪器选择、误差分析等知识。命题的内容主要是气体制备、溶液净化与除杂、溶液配制、影响速率因素探究、元素金属性或非金属性强弱(物质氧化性或还原性强弱)、物质成分或性质探究、中和滴定等基本实验的重组或延伸。
【答题策略】
首先要搞清楚实验目的,明确实验的一系列操作或提供的装置都是围绕实验目的展开的。要把实验目的与装置和操作相联系,找出涉及的化学原理、化学反应或物质的性质等,然后根据问题依次解答即可。
4.有机推断类试题
命题常以有机新材料、医药新产品、生活调料品为题材,以框图或语言描述为形式,主要考查有机物的性质与转化关系、同分异构、化学用语及推理能力。设计问题常涉及官能团名称或符号、结构简式、同分异构体判断、化学方程式书写、反应条件、反应类型、空间结构、计算、检验及有关合成路线等。
【答题策略】
有机推断题所提供的条件有两类:一类是有机物的性质及相互关系(也可能有数据),这类题往往直接从官能团、前后有机物的结构差异、特殊反应条件、特殊转化关系、不饱和度等角度推断。另一类则通过化学计算(也告诉一些物质性质)进行推断,一般是先求出相对分子质量,再求分子式,根据性质确定物质。至于出现情境信息时,一般采用模仿迁移的方法与所学知识融合在一起使用。推理思路可采用顺推、逆推、中间向两边推、多法结合推断。

初中中考化学答题技巧及注意事项免费
化学是一门实用的学科,它与数学物理等学科共同成为自然科学迅猛发展的基础,那么化学中考答题技巧有哪些呢?以下是小编准备的一些初中中考化学答题技巧及注意事项,仅供参考。
一、中考目标:力争中考化学科A率海口市第一名。
二、方法措施:
1、重视化学基本概念和理论的教学,注意对化学实验的复习。
2、备课要抓准重点、难点和易错点,把握课堂。
3、加强课堂教学改革,提高课堂效率,把课堂时间还给学生,把学习的主动权还给学生,使课堂教学真正成为教师指导下学生自主学习、自主探究和合作交流的场所。
4、精讲巧练,跟踪检查。
5、加强与学生的情感沟通,充分利用辅导课,加强培优辅差的针对性和实效。
6、加强反思,每上完一节课,要从中找出成功的、不成功的地方。
7、针对中考新动向,把握中考改革的'方向,培养学生答题技巧、审题和应考能力。
8、注重对学生的心理辅导,让学生轻装上阵。
三、教学内容及进度安排:
1、结束新课(大约两周时间)
2、第一轮复习(大约六周时间)采用的方式是按章节顺序进行,以《达标指导》为依托,使学生初步掌握各章节的知识内容,着眼于基础知识和基本技能,把教材“放大”,将教材中隐含的内容挖掘出来,全面、深入、系统地完成课本上所有知识内容的复习。
3、第二轮复习(大约四周时间)专题复习是依据知识点进行横向复习, 把知识点分为若干个小专题进行复习,是中考复习的关键环节。通过专题复习,加强知识之间的联系与对比,加强知识的融合与应用,能够全面提高学生的综合能力。教学中,通过对本专题中的重要考点进行归纳讲解,以及学习指导等方面的点拨,并剖析适当数量的与生活、社会、环保、科技等实际问题相联系的例题和专题训练巩固知识,形成能力。
4、第三轮复习(约2周半时间)第三轮复习(模拟训练阶段及回归课本):这一阶段是中考的冲剌阶段,具有较强的针对性和紧迫感,因此这一阶段主要通过摸拟训练,有针对性地把历年中考的热点、学生的易错点进行有效训练,最后回归课本。
5、在最后阶段(约考前两周),主要安排学生自我复习,自我完善。由学生自己阅读、消化整理知识、巩固和扩大复习成果。教师则重点加强个别辅导,查漏补缺,提高后进生。

在化学的实验中,不仅要保证过程不出现偏差,更要注意实验中的安全性。下面是读文网小编为您带来的2016中考化学实验操作注意事项,希望对大家有所帮助。
1、取用液体药品操作规范
取用液体药品要少量,在鉴别过程中另外加入试剂后总量不能超过试管总量的1/3,在硬水软水的鉴别中取用样品要等量。取多药品要倒入废液缸而不是原瓶。
2、正确使用胶头滴管
(1)胶头滴管除了量取水外,每次量取其他试剂均需要清洗2——3次,胶头滴管需要用专用烧杯里的水清洗,清洗胶头滴管的水要放入废液缸中。
(2)提醒考生注意,装酚酞和石蕊的胶头滴管是专瓶专用,不用清洗,取多的试剂不必放入废液缸,直接放回原瓶即可。
3、正确使用量筒量取所需要水的体积
(1)量筒量取液体时,将量筒拿起并倾斜与细口试剂瓶接触取用液体(不能将量筒放在桌子上直接倒液体)。然后将量筒放在试验台上平视读数,即使非常接近读数,也用胶头滴管定容。防止因为没有用胶头滴管定容过程被扣分。(2)浓溶液配制稀溶液时先量浓的,清洗后,再量水,必须用桌子上的蒸馏水配制。
4、溶解操作规范
实验中氯化钠固体的溶解和浓溶液稀释均要用到玻璃棒,这两处实验中用过玻璃棒后马上清洗,然后将玻璃棒放到试管架上,再进行下一步实验操作。同学们常犯的错误操作是搅拌后没有清洗,直接将玻璃棒放到试验台上。
5、洗涤仪器的方法正确,仪器、药品整理复位
药匙不可以不擦;玻璃棒、胶头滴管、吸管统一放置(放烧杯里或试管架上);清洗胶头滴管要有专用的烧杯;最后提醒考生注意:试剂复位,仪器清洗,实验台要清理后方可离开。

毒品,一个吞噬着个人生命与前途,一个抹杀了文明辉煌的邪魔。它正扇动着腐臭的翅膀,飞过那段惨痛的历史,来到你我身边,它摧残着人的身躯,荼毒着人的精神,毁灭着人活着的愿望。下面是读文网小编网络整理的珍爱生命,拒绝毒品演讲稿以供大家学习参考。
大家好,我今天演讲的题目是《珍爱生命,远离毒品》。
有这样一首诗:生命诚可贵,爱情价更高。若为自由故,两者皆可抛。我并不同意这样的观点,在我看来生命,是世界上最重要、最珍贵的东西。生命,在有些人眼里甚至比父母还重要。然而,生命在吸毒的人眼里却是一文不值,他们从来没考虑过生命的意义。
毒品,在我们小学生的眼中,是吞噬生命的恶魔,是拆散美好家庭的凶手,是让一个品学兼优的学生变成“瘾君子”的魔鬼,是……在我的脑海里,常听大人说起的毒品有:鸦片、冰毒、海洛因、K粉。在我的记忆中,最可怕的是冰毒和K粉,冰毒只要服用几粒,K粉只要服用几毫克,便会至人死亡,这是多么的可怕!虽然说,我们还小,只读五年级,基本不可能接触到毒品,但我觉得,毒品无处不在。在我们的学校门口,有两条小路,我从来没有走过,因为我不敢走,为什么呢?因为听别人说,小路里吸毒的人很多。还有更可怕的,我九岁那年,我去奶奶家旁边的公共厕所去上厕所,在里面,我借着灯光,看见了几个人在吸毒,她们看了我一眼,我急忙跑了出来。我在报纸上还看见,一个八岁小孩因为吸毒,最终导致死亡。我看了心里想:“为什么人们要吸毒呢?难道生命对于他们来说不重要吗?”
吸毒的下场会是什么呢?偷家里的钱,导致妻离子散,导致死亡。但世上没有后悔药的,这句话会让吸毒的人知道,一点细细的粉末,一片小小的药丸、药片,会毁掉你的一生。因此,我要提醒吸毒的人:吃进去的是一点、一片、一粒小小的毒品,但吐出来的是你那宝贵的生命。
“毒品无处不在,请珍惜生命”这句话应该贴在学校的门口,让所有小学生知道,毒品无处不在,保护好我们宝贵的生命,不要让毒品接触到那朵美丽而脆弱的“生命之花”。在此,我要提醒同学们做到五个“不要”:
一、不要认为毒品是一种“时尚”
二、不要有太强的好奇心,好奇害死猫
三、不要接受陌生人馈赠的食物。
四、不要认为毒品是一种“药品”,不要试图尝试。
五、不要因为炫耀而吸毒,吸毒并不代表有钱。
作为21世纪的青少年,“珍爱生命,远离毒品”要牢记在心,永不忘记!

什么是宪法?宪法是规定公民基本权利和国家根本制度。具有最高法律效力的根本大法。宪法是母法,就像家里的母亲一样。所有的法律都必须根据宪法产生,不得违背宪法,违背宪法的法律是无效的。下面是有读文网小编为你整理的弘扬宪法精神演讲稿,希望能够帮助到你!
同学们,这些你了解吗?
宪法是我国的根本大法。具有最高的法律地位、法律权威、法律效力。宪法是由全国人民代表大会制定和修改的,一切法律、行政法规和地方性法规都不得与宪法相抵触。宪法又被称为“母法”、“最高法”,而我们所知道的《未成年人保护法》、《教师法》、《教育法》、《消费者权益保护法》等这些普通法律则被称为“子法”。 党的四中全会决定,从今年起将每年12月4日定为国家宪法日。
为大力宣传宪法,推进依法治教,学校决定开展以“弘扬宪法精神,建设法治中国”为主题的法制宣传教育活动。通过召开主题班会,办主题小报,听法制讲座,上法制教育课等,弘扬宪法精神、树立宪法权威,学习宪法、宣传宪法、遵守宪法、维护宪法。
四中全会提出的“依法治国”,首先就是“依宪治国,依法执政首先就是依宪执政。同学们,你们知道吗?宪法规定:从你出生的那一天起,你就是中华人民共和国的公民了,国家的兴旺就与你息息相关。宪法还规定:从你满18周岁的那一天起,你就可以参加各个层面的政治选举,拥有选举权和被选举权。
依法治国是我国的治国基本方略,是社会进步、社会文明的一个重要标志,是我们建设社会主义现代化国家的必然要求。有的同学在我们学校上学的时候,不遵守纪律,不听老师的教育,爱小偷不摸,小到别人的一根笔,一块橡皮,大到用暴力手段敲诈同学的钱物,打架斗殴、上网吧等等。小小的年纪,就已经有了许多劣迹。当他们走出我们的校园,或早或晚,可能就走上了犯罪的道路,受到法律的制裁。他们最后走上这一步,并不是一步走成的,其实他们就是在我们这个阶段,我们这个年龄开始一步一步不听教育,渐渐变坏的。
人,不可能自然变得优秀,是内力自我约束和外力强制作用所然。没有规矩,不成方圆;没有纪律,不成体统。人的一生除了学习科学知识外,还要学习法律知识,如果不学习法律知识,你就不知道你的好多权利都受法律保护,如果不学习法律知识,你就不知道你的一些行为已经违法犯罪。
同学们,法律是神圣不可侵犯的,祝愿大家在今后的学习生活中,一同举起生命的盾牌,学法、知法、懂法、守法、用法,依靠法律这把双刃剑,平安、健康、茁壮成长!

演讲稿的演讲者需要对科目内容有系统的了解。初二生物地理会考的演讲该怎么准备呢?下面是读文网小编为您带来的2017年初二生物地理的会考演讲,希望对大家有所帮助。
老师们、同学们:
大家下午好!
阳春三月,万物萌发,这是一个孕育希望的美好季节!今天,我们在这里隆重聚会,吹响了地、生会考冲刺的号角,从现在开始,我们将成为一名勇敢的战士,去迎接一场全新的挑战! 对于本次会考,我这里主要要谈五点:
一、要重视但决不畏惧!地理、生物的会考,应该称为学业考试,由于现在实行的是二考合一,其实质上也就是中考,成绩将无条件带入初三的中考录取,所以,这是你们人生中第一次真正的选拔性考试,我们没有理由不重视!而且,这两门考好了,你们在初三时就能轻装上阵,集中精力学好其它的各门功课;假如考不好,你们将带着一定的思想包袱,影响初三时学习的信心,所以,我们决不能输在起跑线上!但是,面对这两门功课的会考,我们也决不畏惧!
二、相信老师、相信学校、相信自己。理由有四:一是你们很幸运,本届拥有一支非常优秀的极负责任的段长班主任管理团队。这些老师的早出晚归和不计名利的辛勤付出,同学们应该是有目共睹的,希望同学们能深该体会他们的良苦用心,我也相信他们将在会考复习过得中给大家予最大的支持,他们将成为我们的坚强后盾!二是生物地理并不需要你要有很好的基础,只要肯努力,大家都还来得及,按照老师的复习安排去做了,你会发现它们并不象你想象的那么难,功夫到家了,想不考A都很难!三是经过这么多年来的抓会考,地理生物两科科任老师对如何抓好会考也累积了相当的经验。第四点最重要,也就是你们这届学生的总体素质并不比以住任何一届学生差,从初一到现在,你们的课堂纪律以及平时表现都很好,尽管在平时老师也可能对你进行这样那样的批评,但你们中的许多人许多事却时时感动着我们的老师,所以,我对你们有信心!有了以三四个方面的保证,我们何惧之有呢?!
三、心中有目标,学习才有动力,才有努力的方向。
四、结果很重要,后果很严重。守纪、按时、升初三
五、要自信但不自负!通过以上的分析,对于会考,我们要有信心,有了信心,我们也就成功了一半!但在自信的同时,我们却不能自负,毕竟,天上是不会凭空掉下陷饼的!龟兔赛跑的故事,大家大概从幼儿园时就知道了吧?请问正常情况下应该是谁会胜?结果呢?这是为什么呢?是的,回答得很好,乌龟胜就胜在踏踏实实、一步一个脚印,并懂得持之以恒!而兔子败就败在自负上。在座的一些同学,也许你的基础并不是很好,但若能在复习当中注意积累,你就完全有可能像持之以恒的乌龟一样超越一些现在暂时比你强大的对手!而目前基础好一些的同学,若不能保持警惕,也就有可能象自负的兔子一下败下阵来!所以,我们要自信,但千万不要自负!
最后,我想说的是,记得我们闽南歌里有句词叫:三分天注定,七分靠打拼,爱拼才会———赢!很好!我相信大家会笑到最后的!对于这次会考,大家有没有信心?有!很好!谢谢!

在高三的地理考试之前要注意哪些事情呢?下面是读文网小编网络整理的高三地理考前注意事项以供大家学习参考。
强化自信
不管你现在是成绩拔尖,还是跟别人有一定差距,千万别忘了每天都带着信心起床。不论个人情况怎样,每人都有自己的优势和不足。有的同学基础扎实根底深,不论高考如何变,都能游刃有余;有的同学思维灵活敏捷,有一定的创新思维,理解能力强,对考创新的活题尤为适应;有的同学阅读面广,视野开拓,心理素质好,抗挫能力强,善于超水平发挥。不管怎样,在高考前夕,对于自己的缺点和不足不要过多自我责备,要多看、多想、多忆自己的长处和潜力,激发自信心。
每一个有杰出成就的人,在其生活和事业的旅途中,无不以坚强的自信为先导。希尔顿是世界酒店大王,现在他的酒店分支机构遍布世界各地,但他起家时仅有200美金。是什么使他获得成功呢?希尔顿回答说:只有两个字,那就是“自信”。
可见,信心孕育着成功,信心能使你创造奇迹。拿破仑说:“在我的学典里没有不可能这一字眼。”正是这种自信激发了他无比的智慧与潜能,使他成为横扫欧洲的一代名将。
在现实中,自信不一定能让你成功的话,那么丢失信心就一定会导致失败。很多成绩优秀在同学在高考中失利,他们不是输在知识能力上,而是败在信心上。
优化情绪
心理学认为,人的学习生活中,情绪扮演着十分重要的角色,它象染色剂,使人的学习生活染上各种各样的色彩。有这样一个故事,有个老婆婆非常疼爱她的两个女儿,这两个女儿均为小贩,一个卖雨伞,一个卖布鞋,这个婆婆晴天担心大女儿的伞卖不出去,整天哭泣,雨天又担心小女儿的布鞋卖不出去,又整天泪流。街邻叫她哭婆婆。后来一位先生开启她说:“我为你感到高兴。晴天您的大女儿的伞卖得好,雨天小女儿的鞋卖得俏。”婆婆听后,脸色马上转阴为晴,由哭到笑,街邻又叫她笑婆婆。哭婆婆变为笑婆婆的故事说明:同一件事,看问题的角度不同,情绪就不同,结果就两样。变换角度看问题,情绪自然调整过来了。在迎考复习和高考中,要学会转移情绪,将自己的情绪调整到最佳状态。在情绪紧张的时候,听听轻音乐,哼哼小调,或伸伸手,弯弯腰,摇摇脖子,扭扭屁股;或漫步户外,看看云霞,听听蛙声;或与同学聊聊天,讲讲趣事,幽默幽默。考场上可做做深呼吸、望望窗外。通过这些,调节了心理,优化了情绪。
积极暗示
积极暗示能强化自己的信心,消除烦恼。消极暗示会降低人的信心,徒增忧心。考生在考前就要根据自己的情况,进行积极暗示,自我打气。“我行,我一定行”。“我潜力大”。“我进步大”。“我喜欢挑战”。如遇到自己实在解不出的题难题也不要忧心忡忡。从狐狸吃葡萄的故事中我们可以得到启迪,狐狸吃不到葡萄就说葡萄是酸的,这并不是“自欺欺人”,而是“聪明过人”之处。面对一颗自己确实吃不到的葡萄,与其在架下上窜下跳白费力,还不如说这颗葡萄是酸的,另找甜的——自己熟悉的、力所能及的,以长补短,同样可以成功。通过良好的自我暗示,可以驱散忧郁,克服怯懦,恢复自信,激发兴奋点,把自己的心态、情绪,调整到最佳状态。
正常作息
考前保证充足睡眠,蓄精养锐去迎接高考是非常必要的。挑灯夜战,以牺牲睡眠时间去进行题海战术是得不偿失时。殊不知题目浩如烟海,你再做一年、两年也做不完。头天睡眠不足,第二天大脑就处于半休眠状态,思维就处于抑制状态,结果复习无效率,考试就发呆。但也不能走另一极端,认为考前要松手大休一周,停止复习,专调心态,这也会适得其反。心理学家认为,人们如长期处于紧张的工作学习中,大脑中枢会相应建立起紧张思维运作模式,使人能适应紧张的工作学习。如果突然停下无事可干,原来的生物钟就会打乱,心理模式就无从所适,考生会产生失落、不安和心慌等不适的心理现象,所以考生在考前还是按原来正常的作息时间作息。

在上课之前,进行简短的演讲有利于调节课堂气氛。下面是读文网小编收集整理的关于初中课前三分钟演讲范文以供大家学习。
大家下午好,今天我要讲讲安全出行。
生命是惟一的,是宝贵的,世界因为有了生命而变得精彩。我们要珍惜生命,无论是自己的,还是别人的。据不完全统计我国约每年死于交通事故的人数超过10万人,交通已成为“世界第一要害”。如今,作为新一代的我们,一定要遵守交通规则。
在科技飞跃进展的当今社会,车流量相当的多。可能只是一时疏忽,就将酿成大祸。记得四年级的时候,我们班的肖蕾就在十字路口上被一辆飞驰而过的面包车撞上。当时,我虽然没能目睹。但通过同学们的描述,这事有多可怕,她和几个同学一起走来上学的途中,肖蕾冲在最前头,在红灯的时候冲向人行道后来,这时就发生了那惨烈的一幕。肖蕾因为车祸将近半年没来上学。不幸中的万幸是肖蕾只是骨折。但她也因此耽误了学业。肖蕾的是告诉我们一定不能闯红灯! 同样是闯红灯,这位同学就没那么幸运了。放学时,一位孩子,和另外一个伙伴打闹中不慎闯了红灯,其中一位被开来的大货车撞倒在地,司机没有发现,从那个小孩的身上活生生地压过去。导致儿童当场毙命。
一幕幕悲惨的事件发生,一碗的数据触目惊心。我不由感叹:交通事故是那么可怕,一刹那间,就夺走了人的生命.现在路上的车辆越来越多,马路越来越拥挤,同时交通事故也越来越多,每年,有多少的生命被夺走,有多少个家庭被破坏,有多少人要失去亲人了.如果我们每个人心中都有交通规则,每个人都能自觉遵守交通规则。

导语:我们在写论文的时候,免不了要写摘要,那么写摘要的时候要注意哪些事项呢?下面是读文网小编给您分享的一篇摘要注意事项的文章,希望通过这些文字的阅读你能够收获新的知识。
1、字数要得当
书写论文摘要的主要目的是为了便于读者用最短的时间了解研究的主要信息。字数少了难以说明,字数多了又无必要,故论文摘要的字数应该适当。一般而言,中文搞要在250字左右即可,英文搞要可适当长一些,因为英文摘要主要是给非汉语国家和地区读者看的,他们一般没有能力阅读中文全文。
2、描述要具体
应明确说明采用的材料(对象)和使用的方法。在结果部分,要尽量用具体数据说明,而尽可能不用“高于”、“低于”、“大于”、“小于”等笼统字眼,具体数字说明是多高或多低,并注明统计学分析结果,如t值、F值、p值等。p值现在更倾向于列出具体值,如“P=0.002”,而不用“P<0.05”或“p<0.01”等。
3、下结论要客观
作者要采取科学的态度,根据研究结果客观地下结论,结果提示什么,就下什么样的结论。既要避免妄下结论,也不要不敢下结论,“妄下结论”是指有些作者喜欢下言过其实的结论,人为夸大自己研究的重要性,使结论和结果不符。“不敢下结论”是指有些作者存在盲目崇洋和自卑心理,当自己的研究结果与国外的不一玫时,常不敢根据自己的结果下结论。有时甚至为了与国外的研究结果一致,不惜违背职业道德,擅自更改试验数据。这两种做法都是不可取的,需要克服。
4、英文摘要需描述准确
对于一般国人而言,要写出地道的英文摘要的确非常困难,要求过高不太现实。但起码得用词造句准确,不至于让国外读者读后产生歧义。因此,在写英文摘要时,除了要比中文摘要更具体外,还需字斟句酌,争取让国外读者能准确理解论文的主要信息。英文好的作者,可以多花一些时间。英文差一些的作者,最好请英文好的帮助。

在中考英语的备考过程中,我们要避免哪些问题呢?下面是读文网小编收集整理的英语备考的注意事项以供大家学习。
英语语感的培养很重要。其次词汇量有限,阅读面不广,也导致考试中理解判断错误多。
建议:近几年的中考单选题很少单纯考查语法、语言知识,而侧重体现语言形式与意义之间的紧密联系,突出在真实的语境和交际情景中考查英语知识、语法知识,强调将英语知识提升为在语境中解决实际问题的能力。阅读理解中选择的短文体裁多样,题材丰富,如广告、电子邮件、旅游手册、风土人情、科普文化等,话题源于生活,主要考查学生获取信息、处理信息的能力,根据上下文及语境猜测词义的能力,以及在对文章的整体理解的基础上,把握语言材料的主旨和深层含义。

有人说,高考志愿的填报比高考战场还让人紧张,我们要怎样填报志愿呢?下面是读文网小编收集整理的高考志愿填报需要注意的事项以供大家学习。
一般来说,只要考生的高考成绩达到学校在其所在地的录取分数线,但未上所填报专业的录取分数线,在愿意服从专业调剂的前提下,考生可能被调至没有报考并且还未录取满额的专业。但有些学校的某些专业只录取有相关专业志愿的考生,是不接受调剂的。
报考提醒:考生在填报志愿时,对学校《招生章程》要仔细阅读,如果确实很喜欢某个专业,一定要在志愿表上慎重填上这个专业。否则,要想调剂进这些专业几乎是不可能的。而有的高校则提出优先录取有专业志愿考生,如西安交通大学的建筑学、工业设计和软件工程,优先录取有该专业志愿的考生。

诗的意义在于,它是人类观照世界的基本方式之一。现在请欣赏读文网小编带来的翻译好的英文诗歌。
Death Be Not Proud
死神,你莫骄傲
by John Donne
约翰.多恩
Death be not proud, though some have called thee
死神,你莫骄傲,尽管有人说你
Mighty and dreadful, for, thou art not so,
如何强大,如何可怕,你并不是这样;
For, those, whom thou think'st, thou dost overthrow,
你以为你把谁谁谁****了,其实,
Die not, poor death, nor yet canst thou kill me;
可怜的死神,他们没死;你现在也还杀不死我。
From rest and sleep, which but thy pictures be,
休息、睡眠,这些不过是你的写照,
Much pleasure, then from thee, much more must flow,
既能给人享受,那你本人提供的一定更多;
And soonest our best men with thee do go,
我们最美好的人随你去得越早,
Rest of their bones, and soul's delivery.
越能早日获得身体的休息,灵魂的解脱。
Thou art slave to fate, chance, kings, and desperate men,
你是命运、机会、君主、亡命徒的奴隶,
And dost with poison, war, and sickness dwell,
你和毒药、战争、疾病同住在一起,
And poppy, or charms can make us sleep as well,
罂粟和咒符和你的打击相比,同样,
And better than thy stroak; why swell'st thou then?
甚至更能催我入睡;那你何必趾高气扬呢?
One short sleep past, we wake eternally,
睡了一小觉之后,我们便永远觉醒了,
And death shall be no more; Death, thou shalt die.
再也不会有死亡,你死神也将死去。

在考试的时候,我们要知道一些相关事项,才会让我们更加有信心的面对每一个考试。下面是读文网小编收集整理的高三政治考试的注意事项以供大家学习。
政治考试时,要力求慢开始,早入境,快答题,稳结束。要按照由先到后和先易后难的原则答题,前者符合考生的做题习惯,后者有助于稳定考生的情绪,使考生能够进入良性竞技状态。试卷做完后最好要留下一定时间做好如下工作:
认真检查试卷答案
检查过程的第一次工作是看有无遗漏或没有做的题目,发现之后,应迅速完成。
对各类题型的作答过程和结果,有时间要全面复查一遍,时间不够则重点检查。
选择题的检查主要是查看有无遗漏和涂错位的情况,并复核你心存疑虑的项目。但若没有充分的理由,一般不要改变你依据第一感觉作出的选择。
对简答题、论述题等的检查,一是要理论依据和学科特色,另外补充遗漏的内容,删去错误的观点。
对于经济计算题和问答题是检查的重点,你要仔细检阅你是否完成了题目的全部要求;
若时间仓促,来不及验算的话,有一些简单的办法。一是查计算单位是否有误;二是看计算公式引用有无错误;三是看结果是否比较"像",这里所说的"像"是依靠经验判断,如数据是否符合经济现象要求的大致区间和合理范围,答案数字结论是否为整数或有规则的表达式,若结论为小数或无规则,零乱的,则要重新演算,最好用其它方法去做,这是最保险的措施。
