Unit 4 Global warming教学目标1) Learn some knowledge about the greenhouse effect and global warming.2) Know the contents of the text well by talking about this topic and reading.3) Discuss the problem of global warming and express your own opinions学情分析There are two meanings of the term "greenhouse effect". There is a "natural" greenhouse effect that keeps the Earth's climate warm and habitable(suitable for people to live in). Without it, scientists estimate that the average temperature on Earth would be colder by about 30 degrees Celsius (54 degrees Fahrenheit), far too cold to sustain(维持) our current ecosystem. In other words，the normal greenhouse effect is a natural process which is to some degree beneficial to us.重点难点Master the main idea of the first five paragraphs by talking about the topic.教学过程活动1 【讲授】Unit 4Teaching procedures:Step I. GreetingsGreet the whole class as usual.Step II. Lead-inLead to the topic by showing an article to the students and let students know about two types of greenhouse effect ("natural" greenhouse effect and “man-made” greenhouse effect) and their exact meanings.Step III. Analyze two graphs to learn the main idea of the first five paragraphs.From the first graph, we can see that during the 20th century the temperature of the earth rose about one degree Fahrenheit. All scientists agree with the view that the increase in the earth’s temperature is due to the burning of fossil fuels like coal, natural gas and oil to produce energy.More such burning means more carbon dioxide added to the atmosphere.We can see clearly that the levels of carbon dioxide have increased greatly over the past decades.Higher levels of carbon dioxide means sharper increase of the temperature. The phenomenon is called global warming.There has been a debate towards global warming over the pastyears. Opinions about it vary from person to person.Step IV. Read the whole passage to review the main idea of the first five paragraphs and know the two different opinions. Dr. FosterCarbon dioxide has caused the global temperature to ________. An increase of five degrees would be a ____________ and could be very ________.Possible results: __________________(海平面上升)___________________(洪灾)___________________(恶劣的风暴)___________________(干旱)__________________(饥荒)__________________(疾病的传播)___________________________(物种的消失)George Hambley:Any warming will be ______ with few bad ______________________. More carbon dioxide is a _________ thing, which makes crops __________ more and will encourage _____________________.Step V. Discuss the statement: We should take immediate action about global warming.Requirement: Write down your reasons and possible measures on your learning sheetStep VI. Presentation.Ask some students to read their reasons and possible reasons loudly to the whole class.Step VII. Assignment.Make up a complete composition in groups. The passage should include your point of view, your reasons and your measures.精美句子1、善思则能“从无字句处读书”。

全球气候变暖是一种“自然现象”。人们焚烧 化石矿物以生成能量或砍伐森林并将其焚烧时会产 生二氧化碳等多种温室气体。这些温室气体对来自 太阳辐射的可见光具有高度的透过性，而对地球反 射出来的长波辐射具有高度的吸收性，能强烈吸收 地面辐射中的红外线，导致全球气候变暖，也就是 常说的“温室效应”。全球变暖会使全球降水量重 新分配、冰川和冻土消融、海平面上升等，既危害 自然生态系统的平衡，更威胁人类的食物供应和居 住环境。
