垃圾分类,改善环境的英语演讲稿范文

classifying rubbish , improving environment

good morning, respectable judges, teachers. today, standing here makes me feel really honored and excited. the title of my speech is classifying rubbish , improving environment.

personally, rubbish has been a big headache in beijing. as the year 20XX is coming ,every citizen has realized green beijing and green olympics will bring the far-reaching impact on beijing and even all china . the scense of rubbish nearly everywhere has given all of us a really bad impression, and i"m sure none of us wish to show off the bad side of beijing to athletes and journalists all over the world, for it would blemish the city"s and even china"s image and leave a bad reputation. so we really have to work hard on green olympics.

now, we are middle school students. we must improve the sense of protecting the environment and make a contribution to green olympics .

in our life, a lot of rubbish , such as waste paper, plastic bottles ,batteries and so on , is produced every day . after we

learnt the passage make our environment more beautiful , we found a

lot of rubbish thrown into dustbins could be recycled in fact during our discussion. so we thought it would be better if we could classify rubbish . we told our idea to our teacher and he supported us very much . we became volunteers to classify rubbish . firstly we got

three big boxes and put them in a corner of our classroom . one is

for waste paper , one for plastics and coke cans and the other is for batteries . with teacher"s help ,soon all the students took part in the activity of classifying rubbish .in a month , we collected three boxes of paper , a box of batteries and a box of plastics and coke cans .we sold them for 28 yuan and bought some young trees with the money . we planted the trees around our school . we were all spoken highly of by our school principals. now we keep on the job and are

all proud of improving environment .

the world trusts beijing .beijing still has a lot to do to reach the level the world expects, but we have the confidence to make

beijing a green city. great changes are taking place, and not far in the future, beijing will be the focus of all worlds" attention. we"ll grasp the opportunity and do our best to make the sky bluer, water greener and air fresher by the year 20XX.

let"s all wish the best for the 20XX olympics in beijing. thanks for your listening.

垃圾分类,改善环境

尊敬的评委、老师们,你们好!有幸站在这里,我感到是一种荣耀,我此

时的心情非常激动。我演讲的题目是:垃圾分类,改善环境!

应该说垃圾问题一直是困扰我们的一大难题。随着20XX年的临近,每一个市民都深切地意识到"绿色北京,绿色奥运"对北京乃至中国将有着多么深远的

影响!几乎到处是垃圾的情景早就给我们留下了深刻的印象。我相信没有一个

中国人愿意把北京不好的印象留给来自世界各地的参赛队员和新闻记者,因为

它会严重损坏北京乃至中国的形象和声誉。所以,我们必须致力于建设绿色奥

运这一目标。

我们现在是中学生。我们必须提高我们保护环境的意识,从现在做起,为

20XX年绿色奥运做出我们的贡献。

在我们的生活中,每天都要产生大量的垃圾象废纸,塑料瓶,可乐罐,电

池等等。在我们学习 "美化环境"这篇课文时,我和几个同学在讨论时发现许多扔进垃圾桶里面的垃圾实际上是可以回收的。所以我们就想如果能把垃圾进行分类就太好了。我们把想法告诉了班主任并受到了老师的大力支持 . 于是我们几个成了垃圾分类的志愿者。首先我们找来三个大箱子,把他们放在教室的

一个角落里。一个用来装废纸,一个用来放塑料制品和可乐罐,还有一个用来

收集旧电池。在老师的帮助下,很快全班同学都加入到垃圾分类的活动中来。

在一个月内我们就收集了三箱子废纸,一箱子电池和一箱子塑料瓶。这些垃圾

卖了28元,我们用这些钱买了几棵小树栽在了学校的周围。我们的行动受到

了校领导的高度赞扬。现在我们仍然坚持垃圾分类活动,我们以为改善环境出

了一份力而自豪!

世界相信北京,要实现全世界对北京的期盼,北京还有许许多多工作要做。但我们有信心把北京建设成为一个绿色的城市。现在北京的面貌日新月易,相

信在不远的将来,北京将会成为全世界关注的焦点。我们一定会抓住这次机遇

并为之全力以赴。在20XX年到来之前我们一定让北京的天更蓝,水更绿,空气更新鲜!

让我们一起祝福北京 , 祝福20XX年北京奥运会吧!谢谢!

英语演讲稿的格式范文 篇一:写英文演讲稿的格式 篇一:英语演讲稿的格式 最牛英语口语培训模式:躺在家里练口语,全程外教一对一,三个月畅谈无阻!英语演讲稿格式: 从大的方面看,英语演讲词实际上是属于一种特殊的说明文或议论文,其基本组成部分是: 1)开始时对听众的称呼语最常用的是 ladies and gentlemen,也可根据不同情况,选用 fellow students, distinguished guests, mr chairman, honorable judges(评委)等等。 2)提出论题由于演讲的时间限制,必须开门见山,提出论题。提出论题的方法有各种各样,但最生动,最能引起注意的是用举例法。比如:你要呼吁大家关心贫穷地区的孩子,你可以用亲眼看到的或者收集到的那些贫穷孩子多么需要帮助的实例开始。另外,用具体的统计数据也是一个有效的引出论题的方法,比如:你要谈遵守交通规则的话题,你可以从举一系列有关车辆、车祸等的数据开始。 3)论证对提出的论题,不可主观地妄下结论,而要进行客观的论证。这是演讲中最需要下功夫的部分。关键是要把道理讲清楚。常见的论洛基英语是中国英语培训市场上的一朵奇葩,是全球已被验证的东方人英语学习的最佳模式。

洛基英证方法有举例法、因果法、对比法等等,可参见英语议论文的有关章节。 4)结论结论要简明扼要,以给听众留下深刻印象。 5)结尾结尾要简洁,不要拉拉扯扯,说个没完。特别是不要受汉语影响,说些类似“准备不足,请谅解”,“请批评指正”这样的废话。最普通的结尾就是:thank you very much for your attention。 范例: ladies and gentlemen , good afternoon! im 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? 洛基英语是中国英语培训市场上的一朵奇葩,是全球已被验证的东方人英语学习的最佳模式。洛基英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 freshne; it is the freshneof the deep springs of life . youth means a temperamental predominance of

I don't know who wrote these words, but I've always liked them as a reminder that the future can be anything we want it to be. We are all in the position of the farmers. If we plant a good seed ,we reap a good harvest. If we plant nothing at all, we harvest nothing at all. We are young. "How to spend the youth?" It is a meaningful question. To answer it, first I have to ask "what do you understand by the word youth?" Youth is not a time of life, it's a state of mind. It's not a matter of rosy cheeks, red lips or supple knees. It's the matter of the will. It's the freshness of the deep spring of life. A poet said "To see a world in a grain of sand, and a heaven in a wild flower, hold infinity in the palm of your hand, and eternity in an hour. Several days ago, I had a chance to listen to a lecture. I learnt a lot there. I'd like to share it with all of you. Let's show our right palms.

It gives me a headache. Let’s see what will happen if homosexual marriage is permitted by law. According to the international investigation, by 2004, the proportion of gay is around two to five percent of the whole population. And this ratio has been on the rise ever since, especially in the last few years. We know, many countries, such as the US, China, Russia, India and so on, are now confronted with the problem of aging population caused by low birth rates. Once it’s allowed to get married with someone of the same sex, they don’t have their own kids, and then the birth rates may even be lower.

Farewell, Indifference Who was the most well-known figure in China last month? It’s Ma JiaJue—the college student who murdered 4 of his roommates. Many people attributed his crime to his poverty and deficient education. In my opinion, his crime also has much to do with his classmates’ indifference. Indifference is a terrible disease in today’s colleges and the whole society. It’s not rare that two students who have studied together for 4 years have never spoken to each other. It’s not rare that a student who has been absent from class for several days is not noticed at all. It’s also not rare that a student who has severe psychological problems is not cared about at all. Some people may say ‘What the students with psychological problems like Ma JiaJue need is not care but psychotherapy.” However, when people are ill, what they need most is not only medical treatment, but

大学生英语演讲稿范文三分钟

大学生英语演讲稿范文三分钟 Although we would all love to be Ms Popular at home and in the office, at work the task is not to be liked, but to be effective, says computer sales executive Andrea. “This is possibly the single most important lesson we can learn. You can't always be popular. You shouldn't have to be; it's not what you're there for. Progress depends on having your own ideas and sticking to them. And that means having the guts to make difficult decisions when you have to,” she says. We're aware from day one in our first job that every decision we make is either a building block or a stumbling block on our career path. We should use the time to lay the groundwork of future respect by being professional, responsible, innovative, diligent and reliable. Respect is never given for nothing. Claire knew that she was offered a move to Paris with her finance company because she had gained a reputation for keeping cool under fire. And the next step up the ladder would depend on her performance in Paris. “It's essential to build regard if you're going to be able to do what you want in your job,” she says. Winning respect enhances all you do. A proposal for change is more likely to be well received; an application for a raise or a request for promotion is more likely to succeed.
