保护环境的演讲稿100字二年级文字上册
(1) With the improvement of our living standard, more and more people can afford a car. As a result, our roads are more often than not crammed with cars. However, with more and more waste gas being discharged by the cars, the problem of air pollution becomes even more serious. So nowadays we advocate to lead a low-carbon life. My suggestion is we should ride bikes more often instead of driving cars.By riding a bike, we can not only exercise our body but also protect our environment. Why not have a try, my dear friends? 与我们的生活水平的提高,越来越多的人都买得起汽车的。
因此,道路往往没有堆满了汽车。
然而,随着越来越多的废气排放是汽车、空气污染问题变得更加严重。
所以现在我们提倡过低碳的生活。
我的建议是我们应该更经常骑自行车而不是开车骑一辆自行车,我们不仅能锻炼身体,也能保护我们的环境。
为什么不试试,我亲爱的朋友?(2) Now, our side of the car constant more up, the environment also increasingly worse! That the air around us there are many harmful substances. Therefore, we want to Sue around things start to do. For example, we can go to school by bike or walk, it can exercise. If you have time can use less elevator, many climb stairs. We can not only physical exercise, but also to protect our environment. 现在,我们身边的汽车不断的多了起来,环境也越来越糟糕
以至于我们周围的空气有很多有害物质。
所以,我们要苏身边的小事做起。
比如,我们可以骑自行车上学或者步行,这样还可以锻炼身体。
有时间的话可以少用电梯,多爬楼梯。
我们不仅能锻炼身体,也能保护我们的环境。
(3)文章文体:议论文。
文章要点:1.保护环境的重要性;2.学生在家庭中节约能源的具体做法和感想;3.今后的打算。
文章框架:文章应该是三部分两段式。
第一段(包括要点前两部分)1.环保的重要性;2 接着是站在学生的角度谈谈家庭节约能源的具体方法,第二段写第三要点,即谈谈今后打算。
重要句型短语:It is important to protect our environment, the energy in the world is limited. turn off the light and other appliance when you ,re not using them, we'd better not waste the energy, use public transportation, recycle the waste,I can learn more to develop new and clear energy, like the energy from the wind and solar 等。
参考例文: With the development of our society, energy in the world becomes more and more limited, so it is quite important for us to save energy and to protect our environment. As a student, there are a lot of methods we can do to save energy at home. For example, first, we can turn off the light as well as other appliances when we are not using them. Second, recycle the waste water, paper and other waste so that we can reuse them. What's more, it is suggested to use public transportation more instead of private cars. Above all, everyone can make a great contribution to our environment. I hope I can learn more to develop new and clear energy, like energy from the wind and solar.(4)Recently we have held a class meeting to discuss what is considered to be honorable behavior and what is shameful. (最近我们班开了个班会讨论什么是光荣和耻辱。
)It is really a pity to see all this in our school.(很遗憾在学校看到这些现象)Some students don’t respect their teachers or parents. (不尊敬老是和父母)Some don’t take their studies seriously and cheat in exams. (作业不认真,考试作弊)Some throw wastes everywhere and pollute the environment . (到处乱扔垃圾污染环境。
)It is honorable to obey the law and rules , care much about our class and study hard.(关心班级、努力学习、遵纪守法是光荣)It is shameful to break school rules, to be selfish or to make little effort to achieve success.(违反学校纪律、自私 骄傲是可耻的)We should respect others and think more of them than of ourselves.(我们应该尊敬别人经常关心别人)We should work hard and make much more progress to repay the society.(我们应该努力学习取得更大进步从而回报社会。
)We should try our best to keep the environment clean。
(我们应该想方设法保持干净的环境。
) (5) There are still many problems of environmental protection in recent years. One of the most serious problems is the serious pollution of air, water and soil. the polluted air does great harm to people’s health. The polluted water causes diseases and death. What is more, vegetation had been greatly reduced with the rapid growth of modern cities.To protect the environment, governments of many countries have done a lot. Legislative steps have been introduced to control air pollution, to protect the forest and sea resources and to stop any environmental pollution. Therefore, governments are playing the most important role in the environmental protection today.In my opinion, to protect environment, the government must take even more concrete measures. First, it should let people fully realize the importance of environmental protection through education. Second, much more efforts should be made to put the population planning policy into practice, because more people means more people means more pollution. Finally, those who destroy the environment intentionally should be severely punished. We should let them know that destroying environment means destroying mankind themselves.保护环境目前环保还存在着许多问题。
最严重的问题就是空气、水和土壤的严重污染。
污染的空气对人类的健康十分有害。
污染的水引起疼病,造成死亡。
更有甚者,随着现代社会的迅速扩建,植被大大的减少。
为了保护环境,各国政府做了大量的工作。
采用了立法措施控制大气污染,保护森林资源和海洋资源,制止任何环境污染。
因此,在当今的环保中政府起着最重要的作用。
我的看法是,为了保护环境,政府应当采取更具体的措施。
首先,应当通过教育的方法使人们充分謒到环境保护的重要性。
第二,应更加努力把计划生育政策付诸实施,因为人口多就意味着污染严重。
最后,要严惩那些故意破坏环境者。
使他们破坏环境就是毁灭人类自己。
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.Where ever 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 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 box?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 areYes,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!望采纳
有关于垃圾分类的演讲稿,300字左右
垃圾分类,人人有责老师、同学们,早上好,今天我演讲的题目是“垃圾分类,人人有责”或许垃圾分类这一话题,不够朝韩冲突的消息来得那么及时新鲜,也不及讽刺日本的评论显得那么热血澎湃……但是,垃圾分类这一小小的行为却直接关系着我们身边的环境生态问题,这是我们每一个人的责任和义务,所以我也希望,通过我的演讲,大家能有新的感悟。
首先我想给大家做一个小小的测试,请判断我下面的说法是否正确。
用过的纸巾不能和纸张归为一类,不是可回收的垃圾,扔餐厨垃圾的时候,塑料袋要另外扔进可回收的垃圾桶……答案是:对的,因为纸巾遇水即溶,和陶器、烟盒一样,应算作“其他垃圾”的类别,塑料袋本身是可回收垃圾,不能扔进餐厨垃圾堆里。
其实,在我们的生活中,对于垃圾分类,还是存在着许多误区,垃圾分类的意识还不能深入民心。
广州市启动全民生活垃圾分类已近一年,提出垃圾分类已有十年,可目前仍然进度缓慢,即使在公共场所里添置了新的分类垃圾桶,但市民们还是不按分类随意丢弃垃圾,政府说市民的环保意识薄弱,市民又说对于垃圾分类的工作,他们几乎都表示支持,但政府的宣传不到位,也使他们对于垃圾分类的认识不够深刻,即使在居民分类好垃圾后,环卫工人也会把它们混在一起运走,同样也会使垃圾分类前功尽弃。
一环扣着一环,这么多的问题究竟怎样才能协调好呢
子曰:“三人行,必有我师焉,择其善者而从之,其不善者而改之。
”我认为广州或许可以借鉴其他地区的成功案例
关于空气污染的演讲稿100字数
大家好。
今天我所演讲的题目是空气污染.空气污染是大气科学的一个新分支,它是研究在不同气象条件下,进入大气的污染物在大 气中输送、扩散稀释、转化和移除的规律及应用的科学。
本学科萌芽于20世纪20年代, 1921年英国人便进行大气扩散试验,但只是到了50年代后,现代工业的发展和城市人 口高度集中,相继出现了严重的城市或工业区污染事件,以1952年12月的伦敦烟雾事 件为例,夺去了四千多人的生命,这些促使人们对大气污染的广泛关注和研究,到60 年代便逐渐形成这门独立的新学科。
空气污染 由于人类活动或自然过程,向大气中排进了一些有害物质(称污染物),当排入量够多(污染物浓度达一定限度),则使原来洁净空气的品质下降,若这种情况维持时间 够长,便会对人类、动物、植物和大气中的物品产生危害和不良影响,这种大气状态称为空气污染。
组成空气污染有三个要素:污染源、污染物浓度、对人和生物有危害。
洁净大气是人类赖于生存的必要条件之一,一个人在五个星期内不吃饭或5天内不 喝水,尚能维持生命,但超过5分钟不呼吸空气,便会死亡,人体每天要吸10—12立方 米的空气。
由此可见,消除空气污染或保持污染浓度低于某个限度之下,是何等重要。
污染源与污染物向大气排入有害物质的源地称污染源,进入大气的有害物质称污染物。
大气污染源分人工源和自然源, 大气污染的危害与影响 大气污染对人类及其生存环境造成的危害与影响,已逐渐为人们所认识,归结起来有如下几个方面: ①对人体健康的危害。
人体受害有三条途径,即吸入污染空气、表面皮肤接触污染空气和食入含大气污染物的食物,除可引起呼吸道和肺部疾病外,还可对心血管系统、 肝等产生危害,严重的可夺去人的生命。
②对生物的危害。
动物因吸入污染空气或吃含污染物食物而发病或死亡,大气污染物可使植物抗病力下降、影响生长发育、叶面产生伤斑或枯萎死亡。
③对物品的危害。
如对纺织衣物、皮革、金属制品、建筑材料、文化艺术品等,造成化学性损害和玷污损害。
④造成酸性降雨,对农业、林业、淡水养殖业等产生不利影响。
⑤破坏高空臭氧层,形成臭氧空洞,对人类和生物的生存环境产生危害。
⑥对全球气候产生影响,如二氧化碳等温室气体的增多会导致地球大气增暧,导致全球天气灾害增多,又如烟尘等气溶胶粒子增多,使大气混浊度增加,减弱太阳辐射, 影响地球长波辐射,可能导致天气气候异常。
如何防治大气污染,减轻大气污染的危害与影响,构成了当今重大而紧迫的研究课题。
大气污染的防治 防治大气污染是一个庞大的系统工程,需要个人、集体、国家、乃至全球各国的共同努力,可考虑采取如下几方面措施: ①减少污染物排放量。
多采用无污染能源(如太阳能、风能、水力发电)、改革能 源结构,用低污染能源(如天然气)、对燃料进行预处理(如烧煤前,先进行脱硫)、改进燃烧技术等均可减少排污量。
另外,在污染物未进入大气之前,使用除尘消烟技 术、冷凝技术、液体吸收技术、回收处理技术等消除废气中的部分污染物,可减少进 入大气的污染物数量。
②控制排放和充分利用大气自净能力。
气象条件不同,大气对污染物的容量便不同, 排入同样数量的污染物,造成的污染物浓度便不同。
对于风力大、通风好、湍流盛、对流强的地区和时段,大气扩散稀释能力强,可接受较多厂矿企业地逆温的地区和时 段,大气扩散稀释能力弱,便不能接受较多的污染物,否则会造成严重大气污染。
因 此应对不同地区、不同时段进行排放量的有效控制。
③厂址选择、烟囱设计、城区与工业区规划等要合理,不要排放大户过渡集中,不 要造成重复迭加污染,形成局地严重污染事件发生。
④ 绿化造林,使有更多植物吸收污染物,减轻大气污染程度。
通过以上的讲解,大家知道空气对于我们人类的重要性了吧,从现在开始请大家保护环境,植树造林,创造个美好的生活环境吧
刮风可以吹散雾霾,根治还是要解决工业污染,全民齐心对抗雾霾保护环境,雾霾天出门还是要戴口罩的,普卫欣美国进口的天猫有,能有效过滤pm2.5今天,我的国旗下讲话就是这些,谢谢大家。
