教学过程

一、创设情境，导入新课：

过渡：请大家来看下面材料，边看边思考，这些材料反映了哪些问题？

阅读材料：

1.1982年冬天，美国纽约出现22度高温，创百年记录；1987年夏天，希腊雅典出现罕见持续46度高温天气；1988年7月中国武汉高温天气持续25天之久。

2.1985年5月，英国南极科考队首次发现，南极上空臭氧层出现了面积接近美国大陆的“臭氧洞”，它深到可以装下珠穆琅玛峰，而且这个洞还在继续扩大。

3.北京故宫太和殿台阶栏杆雕刻着各式精美浮雕花纹，50多年前图案还清晰可辨，然而现在却模糊不清，有的图案已腐蚀成光板。

问：同学们上述现象反映了什么问题？

生答：全球气候变暖、臭氧层遭到破坏、酸雨危害

教师：这些现象共同反映出大气环境已经出现了很严重的问题。今天就让我们一起学习控制全球变暖。

二、自读课文，思考分析：

1、引起气候变暖的原因是什么？（回答：温室气体的增多）

2、温室气体有哪些呢？

（回答：二氧化碳、甲烷、臭氧、一氧化二碳，二氧化碳的含量最多）

3、二氧化碳对大气有何作用呢？

（回答：大气中的二氧化碳、甲烷等气体，能够强烈的吸收地面的长波辐射，使大气的温度增高，故被称为保温气体。）

4、目前大气中二氧化碳的含量是怎样呢？

学生讨论。

师：据有关资料记载，二氧化碳正以每年0.4％的增长率在增加，科学家预测，到2050年大气中二氧化碳浓度将增加1倍，全球平均气温将上升1.5－4.5度。观测表明，近百年来全球海平面已经上升了10～20厘米。然后进一步提出问题。

为什么二氧化碳的含量在不断的增加呢？

（二氧化碳增多的原因也就是气候变暖的原因）

回答：自然原因

人为原因：

1、燃烧大量的煤、石油等矿物燃料，向大气中排放大量二氧化碳；

2、毁林，特别是对热带雨林的破坏。

教师总结：由此可见，大气中二氧化碳含量的增多导致了大气的保温效应，大气的保温的.效应导致了全球气候变暖。气候变暖给人类和社会带来的影响是利弊参杂，但总的来说是弊大于利，为减缓全球气候变暖，保护大气环境我们如何去做呢？现在就请同学们献计献策。

思考讨论：全球变暖弊大于利，为缓解目前状况，你有哪些锦囊妙计呢？

同桌、前后桌讨论交流：为保护大气环境我们应该怎么做？

教师总结：通过共同交流，同学们都献计献策，共同保护我们的家园，争做“绿色家园”的环保小卫士，精神可佳可贺，但愿能积极投入于行动。但是全球之大，仅靠我们个人的力量还是不够的，那么我们还需要怎么做呢？

总结：6月5日已成为“世界环境保护日”，这足以说明国际社会已达成共识，联起手来共同保护我们的“绿色家园”。

三、总结全课：

1.教师小结，本节课学习内容。（对照板书）

2.学生小结，谈谈收获。

关于全球污染的作文1200字：全球变暖

大气污染

无数次，我看见一根根巨大的刺管昂然挺立，刺向天空的心脏。我听到了天空痛苦的呻吟，在一个被我们忽略的高处。刺管里喷出的黑色的气体，像魔鬼般萦绕，借着隐身的魔法，积蓄着一场谋杀。

无数次，我感觉到空气里迷蒙的窒息，我甚至可以想像整个空间如战场上硝烟弥漫。烟尘、浮粒、有毒物质充斥我们的周身，从一个我们意料不到的方向向我们袭击。

无数次，我可以触摸到院子里那株老树枯黄的叶片，凋零的花朵，早早夭折的花蕾，空气因为雨的洗刷而混杂着的浓重的酸味，那是天空心酸的眼泪，我们给它的，它都还给了我们。

水污染

我无法去面对满塘的“浮尸”，正如我无法悄悄地闭上眼睛，让一切挽回。我无法去面对一湾“死水”，正如我无法亲手关上潘多拉的盒子，让所有苦难结束。我无法去面对一池的“春意盎然”，正如我无法拥有无上的法力，让全部的污水倒流……这个世界有的是水，但都已没用。

固体废弃物污染

清晨六点半，推开阳光，一个人在街上游荡。清洁工在低头默默的清理着肮脏的街道。一堆一堆的垃圾，一车一车地拉走，我在默默地行走，像地上的垃圾。人类与垃圾为伍，也难保不会“进化”成垃圾。

全球变暖，气候异常

全球变暖，南极冰融，暴雨连连，海面上升……一个个问题横空砸来，从一个未知的高度，带着比思想更重的势能，我们被砸得体无完肤。

“珍珠”“碧丽斯”“小天鹅”，一个个比梦还好听的名字，在梦的背后演绎一场残酷的战争，也许这不是战争，而是侵略。逃。无路可退。

人啊，请你站在云端，或者更高的地方，要你明白：这不是人与自然的争斗，这是我们自己跟自己在战斗，我们竟无聊到

跟自己的生命开玩笑。

……

后记：环境污染严重，气温年年上升，暴雨连续不断，世界危机步步紧逼……

地球是属于地球人的，地球是我们的家园，保护地球，人人有责!让我们一

起为保护家园而努力……

关于全球变暖的作文（7）

As is subtly revealed in the cartoons above, global warming is a real threat to our world.

In the first drawing, the glaciers in the polar region are rapidly melting owing to global warming. In the second picture, a homeless polar bear is staying on an isolated big block of ice.

The purpose of these portrayals is to show us that global warming is a looming threat to people all over the world.

To begin with, global warming leads to the rise of sea levels. Large sections Chinese coastal regions would gradually disappear under rising sea levels because of global warming, severely impairing the country’s social and economic progress.

China’s long coastline is the base for about 70% of the large cities, over half of the domestic population and nearly 60% of the national economy.

With comparatively-advanced social, economic and cultural developments, China’s off-shore regions will suffer great losses if the sea level does not cease rising.

In addition, global warming increases the possibility and intensity of extreme weather such as hurricanes and snowstorms.

Hurricanes and typhoons have become stronger and longer-lasting over the past 30 years. These upswings correlate with a rise in sea surface temperatures due to global warming.

Taking into account the devastating effects of global warming, we can draw the conclusion that global warming is a great threat to our world.

Facing the growing menace of global warming, more scientific and active preventive measures should be taken on a larger scale to change for the better.

No one，regardless of race, religion or nationality, can deny that the world we live in is becoming increasingly intolerable because of the effects of global warming. According to many experts, even greater impacts are still on the way.

There are numerous causes for this problem. On one hand, human-related emissions of carbon into the atmosphere is causing, and will in the future cause, significant global warming according to the theory.

On the other hand, the lack of knowledge about the importance of protecting environment hinders the solving of the.

It is urgent that immediate and effective actions should be taken right away.

First, more trees need to be planted to help improve and beautify the environment.

Besides, stricter laws concerning global warming and irresponsible use of fuel resources have to be put into effect and achieved good results.

In a word, there is a long way to go before we can take a comfortable world for granted again .

People around the world may feel that the climate has been getting steadily warmer and warmer in recent years.

Places which used to be abundant in snowfall have frequently experienced snowfree(无雪的) winters.

Drought lasts longer in some dry areas. People find that without air conditioners they could hardly work or fall asleep on hotter summer days.

The side effects of global warming are alarminS. A warmer global climate melts the ice caps, raising sea levels.

What is more, it disturbs weather patterns, causing droughts, severe storms, hurricanes (飓风). People suffer a lot from disasters relevant to global warming.

To stop global warming we should make immediate and continual efforts. We hope the situation will soon change.

Global warming catches and holds our concern, for it affects us and will affect our later generations. We cannot wait any longer. Do it. Do it right.

Do it right now.

关于全球变暖英语作文三

With the development of economy, more and more greenhouse gases are being discharged into the air. CO2 makes up about 70% of the greenhouse gases, which is considered to be one of the greatest causes of global warming. It has harmful effects, causing the sea level to rise and many natural disasters to strike. So we must take effective measures to save our planet. First, we should use more clean energy and less coal and oil. Second, we should go to work on foot or by bus instead of driving a car if possible. Third, we should plant more trees, because plants can turn CO2 into oxygen. More importantly, we should form the habit of saving energy in our daily life.

【参考译文】

正如上述漫画生动所示，全球变暖是当今世界的真正威胁。在图一中，由于全球变暖，极地冰川正在加剧融化。在图二中，一只无家可归的北极熊呆在一块孤立的大冰块上。

这些漫画的目的是告诉我们：全球气候变暖对全世界的人们来说是迫在眉睫的威胁。首先，全球气候变暖会导致海平面的上升。由于气候变暖，中国大多数沿海地区都将随着海平面的上升逐渐消失，严重危害了国家的社会和经济发展。中国漫长的海岸线遍布着中国70%的大城市，人口数量占到全国总人口的一半以上，控制着国家经济的将近60%。这些城市的社会、经济和文化发展程度相对先进，如果海平面继续保持上升的话，那么对于中国的内陆城市来说将会承受巨大的损失。其次，全球气候变暖加大了出现极端天气的可能性并加重其强烈程度，例如飓风、雪灾。在最近30年里，飓风和台风持续的时间越来越长，强度也越来越大。这是与全球气候变暖所带来的海平面温度上升紧密联系的。

考虑到全球气候变暖带来的这些毁灭性影响，我们可以得出结论：全球气候变暖是全球的一大威胁。面临着日益增长的威胁，我们应该大规模采取更加积极、科学的预防性措施来促使其向更好的方向发展。
