教学内容分析
The teaching materials of this period contain three parts.The first part is the reading passage on Page 30 with the title of “What Can We Do About Global Warming？”．It consists of two letters：a request from a student for help on a school project and the reply.The letters bring students' attention to a commonly held belief that individuals are powerless to do anything about environmental problems and that it is governments that are in a position to act and have the responsibility to act.Earth Care's letter suggests ways to save energy and therefore decrease the amount of carbon dioxide that is poured into the atmosphere.
The second part is Exercise 2 on Page 31，which asks the students to make a poster for their school that tells students various ways they can reduce the amount of carbon dioxide in the air.
The third part is a writing task designed by the teacher，which asks students to write a short passage about global warming.By practicing writing the passage，students can strengthen their knowledge about global warming and develop their sense of environmental protection.

The Environmental Effects of Fossil Fuels
There is no doubt that fossil fuels bring a lot of good to us.But do you know that many of the environmental problems our country faces today result from our fossil fuel dependence
The environment faces air pollution，global warming，acid rain，and several other very serious problems because of our use of fossil fuels.Over the last 150 years，burning of fossil fuels has resulted in more than 25 percent increase in carbon dioxide in our atmosphere.
Carbon dioxide is one of the main factors in global warming which is negatively affecting everyone.Fossil fuels also affect water pollution，land pollution，and thermal pollution(heat pollution)．Coal mining is one of the causes of pollution in the environment.After the mining is completed，the land will remain barren.Materials other than coal are also brought to the surface in the coal mining process and these are left as solid wastes.The production，transportation，and use of fossil fuels are to blame for the effects of pollution on the environment.Then what should we do？We should spare no effort to improve our environment.Please save energy and use fewer fossil fuels in our daily lives.
?Step 7 Homework
1．Master the language points in the text.
2．Finish the writing task.
?Step 8 Reflection after teaching

________________________________________________________________________
Global Warming Solutions—What Can We Do
The evidence that humans are causing global warming is strong，but the question of what to do about it remains controversial.Economics，sociology，and politics are all important factors in planning for the future.
Even if we stopped emitting greenhouse gases(GHGs)today，the Earth would still warm by another degree Fahrenheit or so.But what we do from today forward makes a big difference.Depending on our choices，scientists predict that the Earth could eventually warm by as little as 2.5 degrees or as much as 10 degrees Fahrenheit.
A commonly cited goal is to stabilize GHG concentrations around 450－550 parts per million(ppm)，or about twice pre－industrial levels.This is the point at which many believe the most damaging impacts of climate change can be avoided.Current concentrations are about 380 ppm，which means there isn't much time to lose.According to the IPCC，we'd have to reduce GHG emissions by 50% to 80% of what they're on track to be in the next century to reach this level.
Is this possible
Many people and governments are already working hard to cut greenhouse gases，and everyone can help.
Researchers Stephen Pacala and Robert Socolow at Princeton University have suggested one approach that they call “stabilization wedges”．This means reducing GHG emissions from a variety of sources with technologies available in the next few decades，rather than relying on an enormous change in a single area.They suggest 7 wedges that could each reduce emissions，and all of them together could hold emissions at approximately current levels for the next 50 years，putting us on a potential path to stabilize around 500 ppm.
There are many possible wedges，including improvements to energy efficiency and vehicle fuel economy(so less energy has to be produced)，and increases in wind and solar power，hydrogen produced from renewable sources，biofuels(fuels produced from crops)，natural gas，and nuclear power.There is also the potential to capture the carbon dioxide emitted from fossil fuels and store it underground—a process called “carbon sequestration”．
In addition to reducing the gases we emit to the atmosphere，we can also increase the amount of gases we take out of the atmosphere.Plants and trees absorb CO2 as they grow，“sequestering” carbon naturally.Increasing forestlands and making changes to the way we farm could increase the amount of carbon we're storing.
Some of these technologies have drawbacks，and different communities will make different decisions about how to power their lives，but the good news is that there are a variety of options to put us on a path toward a stable climate.

教学内容分析
The emphasis of this period will be placed on listening and speaking.There are altogether two texts for the students to listen to in this period：one is in the Student's Book and the other is in the Workbook.The first one(on Page 31，Listening and speaking)is a conversation between two people，Li Bin and Professor Keeling，who is a scientist studying global warming.Professor Keeling has been mentioned in the reading passage on Page 26.The listening text is a radio interview about the use of fossil fuels and other sources of energy.It contains examples of the focus function for this unit：agreement and disagreement.While listening to Part 1 for the first time the students are asked to decide which statement in Exercise 1 Professor Keeling does NOT agree with.Then students are required to listen to Part 1 again and tick the energy sources that are mentioned in the text.After listening to Part 2 students are asked to list three things they can do to save energy.At last they should also listen to Part 2 again and fill in the blanks in Exercise 4.
The second one(on Page 65，Listening Task)involves an environmental organization.A student，Tom，is giving an oral presentation.As with most oral presentations that students give，Tom has some visual aids to go with his talk.Students will first be required to listen to the whole speech to get the general idea，and then listen again and take some notes about some facts mentioned in the speech.

Ⅰ.国际知名环保组织介绍
这些国际性的环保组织克服了重重困难，获得了世界范围内的响应和支持，依靠组织手段，将提倡的环保概念普及，并通过各种环保项目的实施，切实推动世界各地的环保进程。
(1)世界环保组织(IUCN)
全名为International Union for Conservation of Nature and Natural Resources，缩写为IUCN，该组织历史悠久，1948年即在瑞士格兰德成立，是政府及非政府机构都能参与合作的少数几个国际组织之一。由全球81个国家、120个政府组织、超过800个非政府组织、10 000个专家及科学家组成，该组织共有181个成员国，实际工作人员已超过8500名。组织每3年召开一次世界自然保护大会(World Conservation Congress)。IUCN旨在影响、鼓励及协助全球各地的协会，保护自然的完整性与多样性，并确保在使用自然资源上的公平性，及生态上的可持续发展。
(2)世界自然基金会(WWF)
WWF是在全球享有盛誉的、最大的独立性非政府环境保护机构之一，在全世界拥有将近500万支持者和一个在90多个国家活跃着的网络。WWF的使命是遏止地球自然环境的恶化，创造人类与自然和谐相处的美好未来，保护世界生物多样性；确保可再生自然资源的可持续利用；推动降低污染和减少浪费性消费的行动。该组织的标志为大熊猫。
(3)全球环境基金(GEF)
GEF是关于生物多样性、气候变化、持久性有机污染物和土地荒漠化的国际公约的资金机制。GEF通过其业务规划，支持发展中国家和经济转型国家在生物多样性、气候变化、国家水域、臭氧层损耗、土地退化和持久性有机污染物的重点领域上开展活动，取得全球效益。自1991年启动以来，GEF已通过1000多个项目，向140多个发展中国家和经济转型国家提供了大约40亿美元赠款，并从各种渠道吸引了120亿美元的项目融资。2002年8月，32个捐资国保证，在随后4年内，向GEF提供近30亿美元，用于GEF活动。
(4)国际绿色和平组织
1971年，12名怀有共同梦想的人从加拿大温哥华起航，驶往安奇卡岛(Amchitka)，去阻止美国在那里进行的核试验。他们在渔船上挂了一条横幅，上面写着“绿色和平”。尽管在中途遭到美国军方阻拦，他们的行动却触发了舆论和公众的声援。次年，美国放弃在安奇卡岛进行核试验。在此后的30多年里，绿色和平组织逐渐发展成为全球最有影响力的环保组织之一。该组织继承了创始人勇敢独立的精神，坚信以行动促成改变。同时，通过研究、教育和游说工作，推动政府、企业和公众共同寻求环境问题的解决方案。绿色和平组织在中国的环保项目包括气候与能源项目——致力于减缓由燃烧煤、石油和天然气等化石燃料造成的气候变化，还有致力于消除有毒污染物的污染防治项目，森林保护项目品等。
(5)地球之友(Friends of Earth)
在香港地区创立的“地球之友”(Friends of the Earth International)是著名的环境非政府组织之一，还是反全球化运动的一支重要力量。与其他环境组织一样，“地球之友”近年来也改变了就环境问题谈环境的做法，转而将环境问题与社会问题及发展问题联系起来，既扩大了活动领域，也扩大了影响。自1983年成立以来，“地球之友”曾经走过一段艰辛的路。在香港的超级物质主义的大潮流下，“地球之友”仍然坚守使命，捍卫公众利益，维护环境公义，不屈不挠地推动环保，反对扩充发电厂、滥用杀虫剂、侵占郊野土地、关注过度消费、城市空气污染、水质污染、填海和环境管理失误等问题。
Ⅱ.Kids F．A.C.E.(儿童环保组织“为了世界更清洁”)
Melissa Poe was 9 years old when she began a campaign for a cleaner environment by writing a letter to the then President Bush.Through her own efforts，her letter was reproduced on over 250 donated billboards across the country.
The response to her request for help was so huge that Poe established Kids for A Cleaner Environment(Kids F．A.C.E.)in 1989.There are now 300 000 members of Kids F．A.C.E.worldwide and is the world's largest youth environmental organization.
Poe has also asked the National Park Service to carry out a “Children's Forest” project in every national park.In 1992，she was invited as one of only six children in the world to speak at the Earth Summit in Brazil as part of the Voices of the Future Program.In 1993，she was given a Caring Award for her efforts by the Caring Institute.
Since the organization started，Kids F．A.C.E.members have distributed and planted over 1 million trees! Ongoing tree－planting projects include Kid's Yards—the creation of backyard wildlife habitats(栖息地)and now Kids F．A.C.E.is involved in the exciting Earth Odyssey，which is a great way to start helping.
“Starting the club turned out to be a way to help people get involved with the environment.Club members started doing things like recycling，picking up litter and planting trees as well as inviting other kids to join their club.”
“We try to tell kids that it's not OK to be lazy，” she explains.“You need to start being a responsible，environmentally friendly person now，right away，before you become a resource－sucking adult.”
