环保知识竞赛主持开场白和结束语（英语）
Global Shortage of Fresh Water People often think that water will never be used up.There is plenty of water,suc h as rain,water from the rivers and wells,It seems as if water is always availab le around us and we never have to worry about water shortage. In fact water is rather limited on the earth.With the rapid increase of populati on and fast development of industries,water is more needed than before.At the sa me time,a large amount of water has been polluted and wasted every day.Some big cities in China are facing the problem of water shortage already.There,water sup ly is controlled and industry has been restrained. What should we do about the water shortage?I think,first,the people should be ma de aware of the real situation about the water.Everyone should consciously save on water and certain law should be made that no water will be polluted.We have t o protect the existing water resources and develop new ones.In this way Ibelieve that our cities will be thirsty for water in the future.Today, pollution has become a very serious problem. All forms of pollution do harm to man and animals, such as air pollution, water pollution, soil pollution and so on. Generally speaking, Pollution mainly comes from factories. Each day, chemicals in the smoke from factories cause a lot of damage. Water pollution is also caused by waste from factories. All of these can do harm to people's health. Now people have done something to prevent pollution, but the situation is still serious; we hope scientists will find some new methods to solve this problem.Nowadays, the environmental protection is becoming one of the most important issues in the world. Being one of the members of our society, what shall we do to protect the environment? First, stop using plastic bags, boxes and bottles. Stores should be required to use the bags, boxes and bottles which are made from paper. Secondly, more and more trees and flowers should be planted to keep our surrounding clean. People must be required to plant plants around their houses and work places. Finally, we must control the pollution by law, according to which, polluted water and air exhausted from factories should be forbidden. These are some of the measures that we can take to protect our environment and they are not hard tasks for us. Remember, the earth is the only planet we could live at present. Since the first day, BNBM has paid more attention to protect the environment as its social responsibility, by developing green building materials, producing green products and creating green enterprise. According to the spirit of From the nature, for the nature and return to the mature, BNBM has tried its best in developing new technology and improving equipment to reduce the pollution.为而呐[\\\/color] 1) describe the cartoon 2) interpret the message conveyed in the picture 3) and give your suggestions to remedy the situation 范文 A cry for Nature Conservation As is depicted in the picture entitled “cries from our descendants”, a boy is calling on his ancestors citizens today throughout the world — to ensure a better environment and a greater abundance of natural resources for future generations. With a forced smile on the face, he is crying bitterly and desperately. Such a scene can just put us deep in thought. The drawer of the picture intends to force us to ask ourselves some very thought provoking questions concerning nature conservation. Are we willing to be more conservative in our life requirements, and are we willing to moderate our use of the world's resources for our descendants? Can we, in fact, reduce our consumption of petroleum, coal and electricity, in order to reduce the pollution and environmental pressures created by excessive energy use and to allow others to live a better life? Are we willing to spend more money for pollution control and environmental restoration? Are we willing to devote more effort to recycling? Can we moderate our demand for fat rich diets and super processed convenience food? These are some of the central issues of the present

1，开始班会，简要介绍班会主题，切入主题，请同学们讲讲对低碳生活的理解，估计花5分钟左右，然后可以开展关于环保方面的知识竞赛问答。
估计15分钟的题量。
给获胜者适当的奖励。
2美文诗词赏析，找一篇关于环保的美文，或者诗歌，推荐《自责》《只有一个地球》估计花7,8分钟左右。

4请班主任（学校领导）做总结。
在进行完每个环节的时候，主持人都要适当的总结一下。
如果你们的班会课是45分钟的，主持人就要尽量争取时间，一般领导讲话时间会比较长，班主任大多不会说很多。
主持人就是不能让气氛冷掉，也要尽量把握时间。
如果主持人觉得时间不够，第4个环节可以不需要很多时间。
主持人觉得某个环节大家反映很热烈，就可以继续下去，要是不行，主持人就尽量快点结束这个环节
