Hello:
everyone!
We have only one earth. But now,the environment becomes worse and worse.
As you know,there's no enough clean water for people. So many of them lose their lives because of water. In a lot of countries, people have to cut trees for living. So there's nothing to keep water from running away. Also we have polluted the land, the river and the air. So we have to face more and more floods and droughts .
It's time that we must do something useful to protect our environment. We can plant trees and take good care of them. We can save the water and ask our parents to do so. We can't throw any litter onto the ground and we should collect them for recycling.
If we take good care of our earth today,it will be more beautiful tomorrow.
Hello,everyone!Now I want to talk about a beatiful world!
When I was young,I always dreamed that I lived in a beautiful country. There were many flowers and trees around our city.We counld hear the birds singing and see the children dancing. The streets were clear and the the air was very fresh! How nice it was!But that only was a dream of mine!How I wish that it would be come true! So I think we should do something to protect our environment. Everyone should make a contribution to protect the environment.
Taking care of our environment is very important.Wherever you live,you can do something around your neighbourhood.
Have you ever thrown any litter onto the ground?Have you ever drawn pictures on public walls?Have you ever spat in a public place?Have you ever cut down trees?If your answers are "No",it means that you have already helped protect our environment.
It is our duty to keep our envionment clean and tidy. You might ask yourself,"Have I ever picked up some rubbish and thrown it into a dustbin?Have I ever collected waste paper or bottles for recycling?Have I ever planted any trees or flowers in or near my neighbourhood?"If your answers are"Yes",it means that you have already done something useful to improve the environment.
Now I want to say :Let's do our best to make our world more beautiful!
亲爱的老师们,亲爱的同学们:
大家早上好!
今天国旗下的演讲题目里也有一个“新”字,是《低碳新生活,让我们的世界更美好》。
所谓“低碳生活”,就是减少生活中的二氧化碳排放。低碳生活是普通人新的生活态度。要积极倡导和践行低碳生活,注重节能环保,让我们的生活更美好。
倡导低碳生活,具体为:尽量乘坐公交车出门,减少碳排放;街头买菜尽量不用塑料袋,使用可重复使用的环保布袋;尽量不要使用一次性杯子和筷子;不需要电的时候关掉电源。如果一个小时内电脑不合适,方便关掉主机和显示器;不要长时间吹空调;不需要继续充电时,将充电器从插座上拔下;当你离开教室时,关掉灯和投影仪。
唐代大诗人王维曾写过一首诗:“雨后空山,立秋夜。月光在松林中,水晶石在溪流中”。这首诗描绘了
这样的美丽景色:天色已暝,却有皓月当空;群芳已谢,却有青松如盖。山泉清洌,淙淙流泻于山石之上,有如一条洁白无瑕的素练,在月光下闪闪发光,多么幽清明净的自然美啊!
相信低碳新生活可以让我们的天空重现它本应有的蔚蓝,让我们的森林重现它本应有的郁郁葱葱,让我们的水流重现它本应有的洁净清澈……低碳新生活,也一定可以让我们拥有一个更加美丽的新世界!
同学们,老师们,让我们一起努力吧!谢谢大家!
亲爱的朋友们:
你们好,伙计们!
“地球开始向人类发威了!人类开始注意保护环境。大家没有乱扔垃圾,而是把垃圾收集起来,运到垃圾焚烧厂进行无害化焚烧。街道到处都很干净,人们都很开心。然而,住在地洞里的老鼠却成群饿死了。――原来垃圾无处可寻!”
看完以上材料,你会问:为什么人都懂得保护环境?
近年来,由于人类对环境的不断破坏,世界的未来并不乐观:气温上升导致冰川融化,生物不断灭绝,人类不断砍伐树木,臭氧层出现空洞...这些情况都来自于“厄尔尼诺现象”。这些现象不断向我们暗示:拯救地球!保护环境迫在眉睫!
那么,如何采取行动呢?首先,我们必须减少砍伐树木。树木可以制造氧气和吸收二氧化碳。其次,我们应该保护湿地。保护湿地相当于保护40%~50%的生物物种。
气温上升主要是因为大气中二氧化碳的逐渐增加。所以要降低空气体中的'二氧化碳含量,把未来冰川融化的噩梦扼杀在萌芽状态,让地球彻底降温。减少空气体中二氧化碳的最好方法就是多种树。
此外,气温升高也与垃圾有关。垃圾可以堆肥,但垃圾堆肥时不可避免地会产生甲烷。甲烷也是导致温室效应的“元凶”之一。
因此,人类必须减少垃圾的产生。垃圾少老鼠少,就有了开头故事的一幕。最后,我想提醒大家,保护环境人人有责!
敬爱的老师、亲爱的同学们:
今天国旗下讲话的主题是养成良好的卫生习惯,共创美好校园环境。
校园是我们共同生活的地方,所以养成良好的卫生习惯,共创美好校园环境是我们每个同学的责任。
什么叫习惯呢?所谓的“习惯”是指长期重复地做并逐渐养成的不自觉活动。习惯的力量很大,培养良好的卫生习惯首先应从我做起,我们应该时时刻刻提醒自己,不要随地吐痰,不要随地乱扔废物……那些看似无关紧要的“小恶”可能造成的后果就是使我们的校园变得丑陋、肮脏。我们还要制止其他同学不讲卫生的行为,看到地上有果皮纸屑主动捡起。这些似乎让人不屑一顾的“小善”可以互相促进良好卫生习惯的养成,让我们的校园更加干净整洁。
其次是:我们每位同学都应该自觉地保护教室及其所在班的周围的环境卫生。通过上一周的督促检查,我们发现一年级1班等班级环境卫生做得特别好,并能一直坚持养成这一良好的习惯。每天走进他们的班级,你都会看到桌窗明净,桌凳摆放整齐,地面无纸屑;三年级1班的同学不仅把教室和走廊的地面拖得干干净净,还主动的把他们负责的卫生区拖得干干净净。我想在这样干净整洁的环境里,就会心情舒畅,身心健康。但是走进有些班级,我们还是发现桌凳下面有随便乱扔的废纸,教室里摆放的东西杂乱,特别是黑板下面的粉笔头没人捡起,粉笔灰尘未打扫干净,洗手间因乱扔东西而堵塞起来。教学楼西边的花坛还有同学随意在上面踩踏,这些都是非常不好的行为。我们在检查中发现有的同学竟然把垃圾袋扔在了楼梯口,就不闻不问了,这种行为非常糟糕。对此,我们也作出了严厉的批评。希望今天提出后,同学们能立即改正。
同学们,校园是我们的家,让我们自觉维护校园环境。努力养成不乱扔废纸、粉笔头;不向楼下扔任何杂物;不随地吐痰等良好习惯。同时把班级和卫生区的卫生认认真真做好,并且时时刻刻保持;做到有人检查和没人检查一样干净,一样整洁。一份耕耘一份收获,只要我们共同努力,坚持不懈,我们的校园就会像花园一样一尘不染,空气清新,令人精神爽朗。
让我们在飘扬的红旗下作出我们庄严的承诺:从现在开始,养成良好的卫生习惯,共创美好校园环境。
