你看校园里:操场上干干净净无纸屑,四周围绿树草皮话烂漫,楼房整齐一排排,同学们穿红着绿好漂亮,外面还有绿水青山来拥抱,谁敢说我们的校园不美吗啊?可是今天,老师要实话实说:我们的校园里还有美中的不足,还存在着"丑"的东西。
那么这个"丑"到底藏在哪里呢?
我说这个"丑"就藏在一些同学的嘴巴里。前些天,我路过教室门口,竟听到有同学在相互传唱这样的一首打油诗:(什么)读书苦啊,读书累,读书还要缴学费,不如参加黑社会,有吃有喝有地位
下面还有更难听的,我也不好意思给大家再背下去了。当时,我心情沉重地回到了办公室,跟老师聊起这样的事情。老师们在生气之余告诉我,前些时候还流传过这样一个顺口溜:(什么)一年级是小偷二年级是贼,三年级的美女没人追,四年级的帅哥排成对,五年级的情书满天飞,六年级的鸳鸯成双对。
这是什么话?是怎样的人编造的?其编造的目的又在哪里呢?同学们对这样的一些问题思考过吗?昨天,老师对这些问题,思考了一个晚上,现在我的回答是很肯定的,对于第一个问题--这是些什么话?我说是瞎话瞎讲,以为根本没有这个事实,纯属胡编乱造。第二个问题--是些怎样的人胡编乱造的?我的回答是:是一些胸无大志,不愿学习,只贪图眼前舒服与享受的,又别有用心的人编造的。他们的别有用心又再哪里呢?--他们学坏了,还想让更多的人也跟着学坏。打个比方,他们已经落水了,快要淹死了,还想多找几个人下水陪他们一起淹死,这就是他们的目的。所以,同学们一定要小心啊!
古人说:"言为心声",就是说,一个人的语言直接反映了他的思想。有人说,眼睛是心灵的窗户,我说,语言是心灵的一面镜子,什么样的语言就是一个什么样的人,如果想做一个文明的学生,首先应该从学会说文明的语言开始。
校园是教育人,培养人,塑造人的地方,校园应该是一个美丽而纯洁的地方,所以我们绝不允许此类不文明语言来玷污我们美丽纯洁的校园,毒害小朋友们纯洁美丽的心灵,大家说,对吗?
让我们行动起来,自觉地抵制这些不文明语言的传播。 让我们行动起来,人人都来自觉地使用文明礼貌语言。
让我们人人都来用美丽的语言,给我们的校园再添一份美吧!

保护环境的英语演讲稿怎么写?读文网小编为大家整理了学生保护环境英语演讲稿3篇,欢迎大家阅读。
We all know Tagore.This famous Indian poet once said, “Life is given to us, and we earn it by giving it.” As the saying goes, nature is given to us, and we earn it by contributing to it. However, most people nowadays just want to ask for more from the nature. In fact, they do very little contribution to the nature. Therefore, the environment around us is becoming worse and worse.
Do you often use batteries? Then do you know it takes 50 times more energy to make them than they produce? And just one simple battery can pollute as much water as a person can drink in his whole life. The facts and figures are amazing. So would you please try to use batteries only when it is necessary? If possible, give the used ones to the recycling companies so that they will be made into new ones and won’t be able to pollute the environment any more. Sometimes we become complacent when it comes to recycling, but when you speak in terms of actual facts and figures that everybody can understand, people become much clearer about the problem.
We, as school students, can also join in recycling activities to protect the environment. For example, our class set up a recycling center beside the back door, it is very useful. It is used to collect the waste paper and plastic bottles. In the past, our classmates used to throw all of these into the trashcan. At the very beginning of this collecting activity, it was not so warm-welcomed. Later, more and more people were influenced by the others and joined this collecting activity. Gradually, all the students in our class form a good habit to protect the environment. All of us will now put away the reusable things instead of throwing them into the trashcan.
We should always remember in our mind that protecting the environment is our duty that we can never neglect. Finally would you please let me end this speech with a little poem, “Be kind to the river. Be good to the trees. Smile at the sunshine, and bow to the breeze. Be friendly to nature, and nature will be friendly to you!”

英语演讲稿,不但考验的是演讲者的演讲技巧,还考验演讲者的英语口语能力,是十分有难度的。读文网小编为大家整理了大学生课前三分钟英语演讲稿,欢迎大家阅读。
THE first time I saw Bao was in 2005, the year when Thomas and Uber Cup was held. At that time he was playing against Li zongwei, who is also a good player from Malaysia. Bao beat him. To tell the truth, at first the reason why I liked him was just because I thought he was pretty.*(maybe it is not a suitable word, but I think no better word can describe him, he is really pretty!) From that time, I have focused on him. Then gradually, I found that he not only has good appearance, but also has a talent for badminton.
He is very tall, about 1.90 meters. He is the tallest one among all the players in the Chinese Badminton Team. In 2006, he is chosen as the flag holder stands for China in the opening ceremony in the 15th Asian Games held in Doha. It was the first time that the badminton players were chosen to take over the special task, before which time, it belonged to the basketball players. It was a great honor. And it also proved that Bao was an excellent athlete. We are all proud of him.
He began to play badminton when he was at primary school. In 2000, he won his first good medal, which was significant to him, in Guangzhou. Because of that, he entered the Chinese Badminton Team. As he is as old as Lin dan, who is the top one in the world, he is always put into a situation which is not good to him. He seldom beats Lin dan, so he gained a name which is called’千年老二’. In fact, his techniques are comprehensive, but he is lack of passion, the desire to win is not so strong. So he always has misplays. Due to this, he seldom wins the gold medal. I think this is related to his character. He is easygoing and couth; he looks as if he will never get angry with anybody. So this affects him while he is playing badminton. In a period of time, critical voice has come towards him. He is under great pressure. He was not in the best state. But recently he cheers up again. Several days ago, the Chinese Badminton Championship 2007 was held in Guangzhou. I went to see him on Saturday. I was very excited, and I shouted loudly, hoping he could hear me. There is no doubt that he won the game. Before he went away, he waved hand to us, how excited I was at that time! The next day, he beat Li zongwei again and he won the man’s single gold medal. All of us are very happy. After 7 years, which could be a long time for an athlete, he proved himself again in Guangzhou, which is considered as his lucky place.
I think this will be the energy of his advancing. And I hope he can keep this fighting will and win the gold medal in the 29th Olympic Games held in Beijing!

Ladies and Gentlemen:
My topic is Honesty.
As a correspondent of the Qingdao Morning News, I visited Dr. James Gilman, the President of the International Committee for Marco Polo Studies in England. In this picture, this is James, and this is me and we are looking at a dragon’s tooth. This is a true story. /chuzhong/chusan/ 65 years ago, James lived in Qingdao. Then he was only 5 years old. He often visited the Aquarium and was fascinated by a creature on display there, which he thought was a dragon. He was afraid of its sharp teeth and wanted one to keep as a treasure. In the late 1930s, when the Japanese occupied Qingdao, his family had to leave. On his last day in Qingdao, he ran to the Aquarium and pulled out one of the teeth from the dragon’s mouth. He kept the tooth for the next 65 years, but the feeling of guilt at having stolen it was there in the background all through his life. It was always on his conscience, and the feeling intensified as he became older. Finally he decided to put right his childish error.
In 2002, he visited Qingdao and returned it to the Aquarium with his sincere apologies. He received a warm welcome. When James visited Qingdao, I accompanied him all the time and reported on his visit. I was deeply touched by his honesty. It has taught me a lot. I think to err is human. The important thing is to have the courage to admit and correct one’s error. Honesty is a vital quality of human behaviour. So we should try to keep an honest mind in everything we say and do. I would like to say to all of my friends: Let’s be honest people of good moral character. Thank you.

英语演讲,是指以英语为载体,针对某个话题发表自己的意见和看法,以此来影响、感染听众,达到一种宣传目的的交际活动。读文网小编为大家整理了中学生课前英语三分钟演讲稿,欢迎大家阅读。
Good afternoon ,ladies and gentlemen!
I’m very honored to stand here and give you a short speech! To begin with ,I want to ask a question .Does everybody dream a good dream last night? Actually ,today I want to talk about dream with you. Of course, What I want to talk is not a dream you have last night,but a dream—— about life.
Everyone has dreams about life, different dreams at different life stage,and we need dreams to support us. Dreams are like the stars we never reach in the sky,but like most mariners(水手),we can chart our course by them. With the dream,we have a direction,with a direction, we were no longer confused.With the dream, there is hope,With hope, we have the strength to fight.
But I know,life is tough,and there are always ups and downs, maybe we fail in the way to our aims,and we may feel depressed ,whenever at this time, the dream in our heart can always comfort us, encourage us ,and support us to move ahead .
Young!Fortunately, I am young now. Just due to it, I know that nothing is impossible.I firmly believe that nothing can stand in my way. If
I can't realize my dream,it result from that I haven't work harder enough and I won't find other excuses. If no people believe you, you can make it to prove that you are right. If you think the god haven't blessed you and there is no truth here, you can become the god and create the truth.
"My breath swallows the sky and make the yellow river overflow, my sword is famous in Kyushu and it can collapse the five sacred mountains." At some time in the past I also had am bitious words and I had some achievements. Each achievement results from my hard work. I always believe that "If you want to have more achievements than others, you must work harder."
In some extent, the dream is the hope. If you can insist on doing something, the victory will come.
Hold fast to dreams, for if dreams die, life is a broken-winged bird that cannot fly. Hold fast to dreams, for when dreams go, life is a barren field frozen with snow. So my dear friends, think of your old and maybe dead dreams. Whatever it is, pick it up and make it alive from today. Let's--- move ----out!
Thank you for your listening!

课前三分演讲可以充分利用老师课前准备的时间让同学们听到一些课外的知识,同时也断了同学们的演讲能力,读文网小编为大家整理了小学生课前三分钟演讲稿,欢迎大家阅读。
今天是语文课。我也想说说语文。语文是中华民族国语的基础,是我们学会文字表达的工具,也是我们认识世界、面向世界、改造世界的武器。
我想起了鲁迅先生,他是上世纪初中国文化的旗手。面对贫穷落后的祖国,他立志报国,远渡东洋求医。学成回国后,他发现:中国落后的原因不是疾病,而是文化的落后,他弃医从文,拿起笔杆子,发表很多杂文随感,抨击黑暗落后,唤醒了大众。
我想起了毛泽东,在抗日战争胜利后到重庆与蒋介石谈判,期间发表一首著名的诗篇:《沁园春.雪》,让蒋介石大怒,汇集很多诗人编诗,要抢占鳌头,却一败涂地。毛泽东以激昂文字,指点江山,夺得了中国革命的胜利!在这里,我想告诉大家的是,我对语文的学习,也有一个认知的过程。开始我以为语文不用学,谁不会说中国话?在学习中,我开始认识到学语文的重要性。我在语文课中,不仅学到了写作、阅读、分析,好学到了很多道理。我爱语文课了!
同学们:让我们学好语文,感受到语言的魅力,为今后的成长打下坚实的基础吧!

当你看到校园里“保护环境,人人有责”的标语时有什么样的感触,是视而不见,还是会有一丝留意。读文网小编为大家整理了关于保护环境的学生演讲稿3篇,欢迎大家阅读。
朋友们:
读过美国着名作家欧·亨利小说《最后一片叶子》的人,想必还记得这句话:“当最后一片叶子落下时,生命就都结束了,我也得离开这个世界而去了……”。酷爱生活的女画家约翰西,患了肺炎濒临大限时,“害怕在她轻轻抓着这个世界的手越来越乏力的时候,她会真的像一片轻轻的、纤弱的叶子那样,随深秋的寒凤飘逝而去”。初读这篇小说时,少年不识愁滋味,对主人公那仿佛病态的痴语我并不以为然,而正是在人类对绿色顶礼膜拜,绿色食品,绿色能源、绿色电脑、绿色冰箱,绿色建筑被人们广为崇尚的今天,重读小说《最后一片叶子》,才感悟到,这分明是一个寓言故事,约翰西的心语,分明是谷世之言,大籁希声。
就在欧·亨利自己的国家美利坚合众国的土地上,不是就有过深刻的历史教训吗?着名总统罗斯福对梅花鹿可谓情有独钟,从这点小小的总统私人利益出发,他便下令对北利亚桑纳州一片茂密的大森林进行大规模扫荡,大批鹿的天敌——狮子、狼等食肉动物被捕杀殆尽。四千多只鹿于是生物爆炸一般,呈几何级数迅猛增长,十几万只伸特长脖子的可爱精灵们,吃光了树上的叶子,仿佛只在转眼问,着名的大森林就从地球上消失了,最后剩下的,只有凡头病鹿。鲁迅先生说过,悲剧是把美好的东西毁灭给人看。
在我省南部,有一个美丽的地方,她向来就被人们称为镶嵌在我们这个植物王国皇冠上的一颗绿宝石。她的美丽,当然是绿色赋予的。可是,就在这绿宝石之上,有8家红砖厂的大烟囱,不分昼夜地喷吐着氟化物和二氧化硫严重超标的浓烟,致使1262亩的天然橡胶林受害,三万零五百株橡胶树为之枯死,胶民们虽然怨气沸腾,却眼睁睁地奈何不了它,无独有偶,在同一纬度的广西某地,也上演过惊人相似的一幕,如果说那一幕还有点不同的话,就是红砖厂的废气除了使大面积胶林枯死外,还造成50多亩芒果只开花不结果,出现果荒。我们知道,天然橡胶是目前地球上极为少有的自然资源,仅生长在赤过附近,我们也知道,芒果是公认的“水果之王”,那么何以会出现上面那样的情况呢?——因为红泥巴变成砖块,只需要几天的时间,远比橡胶芒果来钱要快!
绿色是和平和生命的象征。在很小的时候,我的心便融进了一个绿色的海洋。穿了十凡年国防绿的我,在老山战区那片阳光充足,绿色位浓的亚热带丛林中,度过了人生位美好的一段年华。就是在那样一个空气、阳光、风雨充足的天然大氧吧里,我步入了而立之年。此生最难忘的,能维系裁生命的,大概就只有那特殊的一片绿色了。而事实上,那片我魂牵梦紫的土地至今还不富裕,一些地方生产力水平低下,社会发育程度不高,边民的农事,至今还离不开刀耕火种,纵火烧荒。我曾目赌过两个边民合伙买一盒火柴平分的事,开始想当然地以为他们太穷,买不起一盒囫囵的火柴,后来才发现,在他们的生活里,四季灶膛火不断,一根火柴烧一年,大树小树变成灰。我能给他们的,就是一个毫无用处的忠告:可别把咱的林子都烧光了呀。
人类只有一个地球,我们对这个星球上的生态系统有着永远摆脱不究的依赖性,需要地球源源不断地提供植物和动物的食物,需要有足够厚度的大气层,来保护人类不受过高成过低气温,以及过量紫外线的伤害,需要地球提供足够量的水和氧气来维持生命的存在,而没有了绿色,这一切岂不成了无本之源,好比毛长在皮子上,没有了皮,毛又咋生根?
绿色锐减,吞噬绿色的,正是人类自己,是人类发展模式中那种对自然资源的掠夺性、破坏性开采。人类对绿色的无尽索取仍在威胁着生态平衡,破坏着生态的结构。据保守统计,全世界每年有XX万公顷森林横遭盲目砍伐,这是5700个昆明市的面积啊。这已经造成了全球性的“温室效应”,与之相连,全世界每年有近5万个物种濒临灭绝,有近2700万公顷的农田蒙受沙漠化之灾,就连海底也日趋沙漠化,就不必再说那令我们痛心的去年在华夏大地发生长江、松嫩大灾了吧,也不必说我省的泥石流,山体滑坡了吧。如此盲目的行动如果得不到有效的制止和改变,势必爆发可怕的生态危机,而一旦它的爆发起出了人类控制的极限,其后果不堪想象。那时,我们都会明白,最后一片落叶将带走人类的命运,也决不是危言耸听。
我们欣喜地看到,可持续发展战略已经纳入了我目的政府行为,我国已颁布了10多部环境保护法,200多项环境标准,绿化财政,正威为人们的自觉意识,“天人合一”。更是我们千年的愿望,我想我们应该叫响这样一个口号:绿色就是生产力!我省的金沙江等流域,炊坑代木兮,豆之河之干兮现象也已悄然消失。你可能问我,这一切还保不住你那最后一片叶子吗,那么,我要说的是,你还是去问问我们的《国歌》里,为什么至今还要唱“中华民族到了位危险的时候”这一句吧。诚然,正像我们的抗洪收灾能取得决定性胜利所昭示的那样,我们坚信,人类的本事能够挽狂澜于既倒,扶大厦之将倾,但是,常言说的好,人无远虑,必有近忧,居安思危,要防患于朱然。我们怎么能够等到头上见不到日月星辰,满目酸雨纷纷,脚下洪浪滔天,汪洋恣肆,人间无处不飞沙,等到“千山鸟飞绝,万径人踪灭”时,才悔不当初呢?
聪明的作家欧·亨利是以其“欧·亨利式的结尾”着称于世的,那最后一片不凋的叶子,带来的是一个危亡病人的新生。我想,我们也会创造出另一个欧·享利式的结尾,迎来人类新生的。坐以待毙,从来就不是人类的选择,人类既已觉臣,就会在危机面前积极行动起来,把握历史机遇,化压力为动力,保卫绿色,保护我们共有的家圈。
面对现实,我们迎接挑战,展望未来,我们充满信心

hello, ladies and gentlemen. i’m angela zhang from class 4 grade 8. today, my topic is, “the shanghai world expo”.
first, i’ll say something about world expo history. as we know, the very first world expo, the great exhibition of 1851, took place in the crystal palace in london. uk. ever since then, the goals of world expos have been both high-minded as well as commercial. visitors are able to explore the world outside of their everyday experience—outside cultures, new scientific advancements, and new inventions. world expos have excited and inspired more and more people in the world.
on december3, XX, the bureau of international expositions (or call it bie) announced that shanghai will host expo2010. the bie had received bids from five cities to host expo2010. among the 5 nice cities, the bie chose shanghai at last! it’s really an exciting news for not only shanghainese, but also all of chinese people. here are some details about it.
look at this profile carefully. the title is “the 2010 world exposition ,shanghai, china ”. this is the logo.
and the theme is “better city., better life”.ok, let’s guess who is the image representative? yeah, you’re right, yao ming!
shanghai expo is the first comprehensive world expo held in a developing country. and it is also the first one that takes “the city” as its theme, hoping that it can push forward the city development and help bring about a better urban living environment, just like the theme: better city, better life.
i think, as a student in shanghai, we should learn to be a gentle person and keep good manners from now on. and try to practice english more in order to communicate with foreigners fluently in the near future. because, we’re a part of shanghai!

Honorable judges, distinguished guests, ladies and gentlemen:
It is a great honor and pleasure to be here on this beautiful Saturday morning to share with you my sentiments about life and passion for the English language.
About a year and a half ago, I took part in my very first English Speech Contest. When I stood before the microphone with all eyes starring directly at me, I could hardly speak. I stood there, embarrassed and helpless, struggling in vain for the right thing to say. My fears had paralyzed me.
While my passion for English has never changed, I lost my courage to speak in public. When my professor again encouraged me to take part in this Competition, I said “no.” I couldn’t endure yet another painful experience. He looked me straight in the eye and said something that pierced my heart. I will never forget his words. “Look,” he said, “We all have our fears, and you have yours. You could twist your ankle in a basketball game, but then be afraid to ever play again. Running away can never dispel your fears, but action will. A winner is not one who never fails,but one who never quits.”
I spent a whole day with his words twisting and turning in my mind. Then I made the bravest and wisest decision of my life: I would face my fears – and take part in the competition!
As it turned out, my dear old professor was right. Now, here I am, once again standing before a microphone. My heart is beating fast, and my mouth is dry, but most importantly, I have faced my fears -- and that makes all the difference!
Thank you.

同学们:
大家好!
有个女孩,在月台上追赶一张被风吹飞了的纸。热心的人们看见她万分焦急的样子,以为那是一张对她十分重要的纸,便纷纷加入追赶的队伍,可那张纸仿佛要存心捉弄大家,飞起又落下,落下又飞起来,像附了魂一样。越是这样,女孩追它的决心就越大。
终于,在众人的努力下,那张纸乖乖地就范了。那个追到纸的人,得意地将战利品递给女孩。女孩优雅地向大家道谢,然后拿着纸在众目睽睽之下走到一个垃圾筒跟前,将它塞了进去,回过身,她微笑着对大家说:好了,现在它终于去了它该去的地方。
故事讲到这里,也许你会诧异于女孩的举动,也许你会怀疑于故事的真实。好了,先放下这些都不说,同学们,让我们闭上眼睛一同想象:在我们的周围,在我们的身边,是否有垃圾从同学的手中滑落,成为路面上醒目的感叹号?是否有随手丢弃的塑料袋在风中“翩翩起舞”?是否会在厕所洁白的墙壁上看到几个刺眼的脚印?
同样的,在你的周围,是否有人大声叫嚷,让你的耳膜阵阵发聋?是否有人口出脏话,污言秽语,招来人们鄙视的目光?是否有人唏嘘起哄,吹口哨,叫人不可思议,令人费解?

眼睛是我们的心灵之窗,保护眼睛,从点滴做起。读文网小编为大家整理了3篇有关于保护眼睛的演讲稿,欢迎大家阅读。
在进入电脑时代的今天,许多同学要经常面对电脑屏幕学习、娱乐,其中有些同学会感觉眼睛吃不消,眼胀、流泪、头痛等等,还有些人发生视力下降。那么,长期接触电脑荧屏究竟对人的眼睛哪些影响呢? 专家认为电脑荧屏对眼睛有下面一些影响:
眼胀和头痛:由于长时间双眼紧盯荧屏,荧光屏上各视力点间的亮度和视距频繁闪烁变化,眼睛为看清荧屏文字、图形等信息内容,必须紧张地进行自我调节。这样,眼睛的调节肌--尤其是睫状肌必须频繁活动,久之睫状肌就会疲劳,即眼疲劳。这就是使用电脑过度或者长时间看电视之后产生眼胀和头痛的主要原因。
容易近视:青少年长期接触电脑荧屏(或者长时间玩电子游戏机),眼睛调节加强,就会造成调节性近视,若不及时防治,很快就会演变成真性近视。
易患干眼症:长时间专心致志面对电子游戏机或电脑屏幕,眨眼次数显著减少,使角膜、结膜缺少泪液湿润,久而久之会出现结膜干皱,角膜上皮脱落,患者有刺痛感。 以上这些电脑荧屏对眼睛的影响用什么方法来防止呢?保健专家建议:
1 、在计算机等显示屏幕前,放置一面有色透明遮挡板,它除了可以吸收掉大部分有害射线外,还可以适当降低其亮度,减少对眼睛的闪烁刺激。
2、制订荧屏作业卫生规则,每工作一小时后应立即休息一刻钟,全天作业时间控制在4个小时之内。
3、坚持每天做眼保健操和体育活动。
4、观看电视的时候,应距屏幕2.5米以外,观看时间控制在一天3小时之内。幼儿和少年儿童要尽量少看电视,儿童不宜玩电子游戏机,成年人玩时也要控制在40分钟之内。

早上好!当我们抬起头注视着鲜艳的五星红旗冉冉升起时,你们有没有想过:是什么让我们看到了这激动人心的情景 对,是我们的眼睛! 眼睛是心灵的窗户,拥有一双明亮的眼睛是一件多么幸福的事情。我们每个人小时候都拥有一双明亮的眼睛,拥有过夏夜繁星闪烁的天空。可是渐渐地,由于读写姿势不当,用眼过度,许多人的视力不断地下降,蓝天不再明净,繁星变得一片朦胧。看看,我就是这样一个例子。我想,各位一定不愿眼镜带来的不便伴随自己一生吧!6月6日是世界爱眼日,虽然今年的爱眼日已经过去,但是我们每时每刻都应牢记保护眼睛。有资料显示,我国眼睛不好的人数居然仅次于世界第一的日本,因此也被称为"中国眼"。我国的盲人达到了500万,占全世界盲人总数的18%;而且每年约有45万人失明,这意味着几乎每分钟就会出现一例新的盲人。我国的近视率达到了1000万。保护视力刻不容缓,为此,我呼吁:为了你能继续拥有一双明亮的眼睛,为了你能拥有更明净的天空,每一位同学都要把保护眼睛的信念牢记心中,都要把爱护眼睛的要求落实到自己的日常行为中。为此,我建议各位作到如下几点:
1,始终保持教室内充足的光线,光线不足时要及时开灯。
2,看电视和操作电脑时,要保持一定用眼距离和坐姿的端正。眼保健操要正确到位。
3,养成良好的读书写字习惯,读写姿势要端正,背部要伸直,颈部保持直立,做到"三个一",也就是眼睛离书本一尺,手指距笔尖一寸,胸脯与桌子隔一拳。不正确的握笔姿势和不良的读书习惯要随时纠正。走路和乘车时也不要看书,不要躺着看书,不在光线过强或过暗的地方看书。4,保证充足的睡眠。充足的睡眠是消除疲劳,恢复学习能力的重要原因,也是保持身体健康的主要因素。5,多做户外运动,经常远眺,使眼睛得到休息,调节视力,解除疲劳。
6,不偏食,多吃奶制品,鱼蛋,肉等,少吃糖果和含糖高的食品,合理的安排我们的饮食结构,从饮食中获取充分的营养物质。多吃蔬菜,尤其是胡萝卜等含多种维生素的食品。做到以上6点并不难,只要同学们自觉执行,只要老师们随时提醒,及时纠正,我相信,同学们一定会拥有一双更清澈,更明亮的眼睛,一定会拥有一片更广阔,更明净的天空! 另外,6月11日是全国人口日,加强人口教育也是非常重要的问题。作为当代的中国学生必须了解我国人口的历史和现状。我国有13亿多人口(不包括香港,澳门特别行政区和台湾省),占世界总人口的22%。农村人口比重大,年龄结构比较年轻,老龄化问题已经出现,人口地域分布不均,人口素质较低。全国人口中,具有大学程度(指大专及以上)的人口为6764万人,高中程度(含中专)的人口为15083万人,初中程度的人口为46735万人,小学程度的人口为40706万人。过去人们常用地大物博来形容中国自然资源的丰富。但是,随着人口的迅速增加,我国人均资源占有量在急剧下降,我国是一个发展中大国,又是一个资源小国,能源资源的总量虽然位居世界前列,但人均占有量却很低。据统计我国人均土地面积0.8公顷,人均耕地0.11公顷,人均草地0.33公顷,人均森林面积0.1公顷,分别为世界人均值的29%,33%,42%,26%;人均原油可采储量2.6吨,人均天然气可采储量1074立方米,人均煤炭可采储量89.8吨,分别为世界平均水平的12.5%,4.5%,50%。人均占有量远远低于世界平均水平,而我们却未意识到它的严重性。所以,我们要认识到我们与世界强国的差距,从现在起,认真学习科学文化知识,提高自身素质,懂得珍惜资源!为了美好的未来让我们一起努力吧!谢谢各位!

动物是人类的好朋友,我们要保护动物。读文网小编为大家整理了小学生保护动物演讲稿3篇,欢迎大家阅读。
老师、同学们:
大家好!
我今天演讲的题目是——保护野生动物。
大家都认识熊猫,它们既可爱又机灵,不但淘气,还会自我保护。
熊猫很机灵。它经常让小林鼠自己跑出来让它吃,当然也会使用一些计策。
它还很淘气。有时,它趁猎人不在家,大摇大摆地闯进去,偷吃猎人的野味。吃完了,还把勺子仍得远远的,甚至把锅挂在树杈上。
当敌人来时,它能很好地保护自己,不被敌人吃掉。
但是,现在,像熊猫这样可爱的野生动物也越来越少了,豚鹿、梅花鹿那样的之前在小山坡上就能看见的动物,现在早已不见了踪影。
朱鹮、金雕、白鹤这些华丽、美丽的鸟儿们,在几亿年前曾经数不胜数,但现在只能在动物园里才能见到它们的美丽的模样了。
巨蜥、扬子鳄、蟒,这些动物虽然很危险,但也是重要的野生动物物种,对自然界的生态平衡也起着一定的作用。
说到这儿,你们想到了什么呢?我们不能因为他们的肉美味,就随便乱杀。它们可怜,是因为它们的兄弟姐妹越来越少;它们害怕,是因为自己有被杀的风险;它们生气,是因为我们的过度开发,它们的领地已经越来越小了。
从现在开始,不要再乱杀野生动物!从现在开始,不要再大量开发森林!不要再破坏动物和动物的家园吧!
谢谢大家!

保护环境是我们每个公民的职责。读文网小编为大家整理了关于保护环境学生英语演讲稿4篇,欢迎大家阅读。
Development and the Environment
It is undeniable that the worsening environment has become the biggest concern of the present-day world. Land resources are dwindling because of water loss and soil erosion. Waste gases poison the air we breathe. The rivers and lakes are polluted by waste dumped in them from factories. It is probably no exaggeration to say that deterioration of the quality of the environment threatens the existence of mankind itself.
Some people are of the opinion that the environmental problem is the price we have to pay for economic development. But I do not think that this argument is valid. After all, what is the point of economic growth if people’s lives are adversely alfected by worsening environmental pollution?
There is plenty of evidence to show that sustainable development can be achieved by balancing economic growth with protection of the environment. The key to achieving this is to make people aware of the seriousness of the problem. Both governments and ordinary citizens should join hands to make this world a better place to live in, not only for ourselves, but also for future generations.
