Unit 3　Environmental Protection (见学生用书P53) Soylent Green 《绿色食品》 Soylent Green was one of the first films to treat the environmental issue in an alarming way. It really captured① the people’s attention because of the heavy industrialisation of the 20th century. Soylent Green is a very strong film in terms of environmental awareness. 《绿色食品》是第一部以警示的方式对待环境问题的电影之一。由于20世纪的过度工业化，它确实吸引了人们的注意力。《绿色食品》是一部带有非常强烈的环境意识的电影。 (1)Soylent Green——It’s what we want; it’s what we need. 绿色食品——这就是我们所想要的；这就是我们所需要的。 (2)Soylent Green is people. 绿色食品就是人类。 Dersu Uzala 《德尔苏·乌扎拉》 The film talks about the deep connection between man and wilderness. Akira Kurosawa also tries to demonstrate② the might of nature as an unforgiving force, strong enough to bend even the most savage③ of the creatures. 这部电影讲述了人类与荒野之间的深厚联系。黑泽明还试图展示大自然令人难以对付的力量，强大到足以让最野蛮的生物屈服。 (1)Man is small before the face of nature. 在大自然面前，人是渺小的。 (2)How can man live in a box? 人怎么能住在盒子里？ Life Out of Balance 《失衡生活》 The film is an almost Buddhist meditation④ on our environment, both found and constructed. Tedious⑤ at first, but once you get into the zone, the film will reveal itself as amazing. 这部电影几乎是对我们所发现和构建的环境的一种佛教式的沉思。一开始很乏味，但一旦你进入状态，这部电影就会展现出惊人的魅力。 (1)Life is all about balance. 生活就是平衡。 (2)You don’t always need to be getting stuff done. Sometimes it’s perfectly okay, and absolutely necessary, to shut down, kick back and do nothing. 你不需要总是把事情做完。有时候，完全可以，也绝对有必要，停下来，放松一下，什么都不做。 Kifaru 《基苏》 It tells Sudan’s story through the eyes of his Kenyan caretakers.

There is little doubt that Earth is getting warmer and warmer (see the graph②). A warming ocean and atmosphere③ along with melting ice④and rising sea levels provide evidence⑤ of a dramatic⑥ change in the global climate. In 2013，a lot of people were shocked by a news photo of a dead polar bear that was found on Norway’s Arctic island of Svalbard. According to⑦ the scientists who found its dead body，all that remained of the polar bear was “skin and bones⑧”．An expert who has studied polar bears for many years said that from the position of its dead body，the bear appeared to have starved⑨ and died. Experts claimed⑩ that low sea­ice levels caused by climate change meant the bear could not hunt seals as before，so it had to travel greater distances in order to find food. This alarming⑪ case showed how the increase in temperature had an impact on⑫ Earth’s ecology⑬. Then what is causing the increase in the global average⑭ surface temperature? Climate scientists often mention a key climate process called the “greenhouse effect”，which has two common meanings: the “natural” greenhouse effect and the “man­made” greenhouse effect. The “natural” greenhouse effect refers to⑮ the fact that heat from the sun enters the atmosphere and warms Earth’s surface as short­wave⑯ radiation.The heat is released⑰ back into space at longer wave lengths⑱. Greenhouse gases in the atmosphere，such as methane⑲ and carbon dioxide⑳，trap some of the heat，keeping Earth’s climate warm and habitable㉑. Without this process，Earth could not sustain㉒ life. However，the “man­made” greenhouse effect has now become a big problem. When people produce huge amounts of extra㉓ greenhouse gases by burning fossil㉔ fuels，more heat energy is trapped in㉕ the atmosphere and causes Earth’s surface temperature to rise quickly. There is strong and comprehensive㉖ evidence that the rise in temperature has led to an increase in extreme㉗ weather and natural disasters worldwide㉘，not only causing serious damage，but also costing human lives. Climate scientists have warned that if we do not take appropriate㉙ actions，this warming trend㉚ will probably continue and there will be a higher price to pay. In fact，news reports are frequently broadcast㉛ about extreme rainstorms and heatwaves causing deaths and economic losses. Continued greenhouse gas emissions㉜ will result in㉝ further warming and long­lasting㉞ changes to the global climate. This requires the attention of people all over the world. Governments need to consider making policies and taking appropriate actions and measures to reduce greenhouse gas emissions. We as individuals㉟ can also reduce our “carbon footprint㊱” by restricting㊲ the amount of carbon dioxide our lifestyles produce. It is our responsibility to seize㊳ every opportunity to educate everyone about global warming，along with its causes and impacts，because this is the most serious issue affecting all of us on this planet. So what will you do to help？ 译文 气候变化需要全世界的关注 我们已经知道气候变化几十年了。毫无疑问，地球正变得越来越暖和(如图所示)。海洋和大气的变暖、冰的融化和海平面的上升，为全球气候的剧烈变化提供了证据。 2013年，在挪威北极斯瓦尔巴群岛上发现的一只死亡的北极熊的新闻照片令很多人震惊。据发现其尸体的科学家称，北极熊仅存的是“皮包骨头”。一位研究北极熊多年的专家说，从北极熊尸体的位置来看，北极熊似乎是饿死的。 专家称，由气候变化导致的低海洋冰川位置意味着这只熊不能像以前那样捕猎海豹，因此它必须走更远的距离才能找到食物。这一令人担忧的案例呈现了温度的升高是如何影响地球生态的。 那么是什么导致了全球平均地表温度的上升呢？气候学家经常提到一个关键的气候过程，叫作“温室效应”，它有两个常见的含义：“自然”温室效应和“人为”温室效应。“自然”温室效应是指太阳产生的热量以短波辐射的形式进入大气并使地球表面变暖。热量以较长的波长被释放回大气层。大气层中的温室气体，如甲烷和二氧化碳，捕获了一些热量，保持了地球气候的温暖和宜居。没有这个过程，地球就无法维持生命。然而，“人为”的温室效应现在已经成为一个大问题。当人们通过燃烧化石燃料产生大量额外的温室气体时，更多的热能被困在大气中，导致地球表面温度迅速上升。 有确凿而全面的证据表明，气温上升导致全球极端天气和自然灾害增多，不仅造成严重破坏，而且造成人员伤亡。气候学家警告说，如果我们不采取适当的行动，这种变暖趋势可能会继续下去，(人类)将付出更高的代价。事实上，有关极端暴雨和热浪造成死亡和经济损失的新闻报道经常播出。 温室气体排放量的持续增加将导致进一步变暖和全球气候的长期变化。这需要全世界人民的关注。各国政府需要考虑制定政策，采取适当行动和措施减少温室气体排放。我们作为个人也可以通过限制我们的生活方式所产生的二氧化碳量来减少我们的“碳足迹”。我们有责任抓住每一个机会，教育大家认识全球变暖及其原因和影响，因为全球变暖是影响我们地球上所有人的最严重问题。那么你会做些什么来帮忙呢？ Step 1　Pre­reading How is our living environment being polluted today? It is polluted by increasing industrialisation, greenhouse gas emissions, deforestation and so on.(答案不唯一，合理即可) Step 2　While­reading Task 1：Fast reading 1．Answer the following questions. (1)The text is mainly about climate change and environmental protection . This text may come from an environmental magazine . (2)What is the author’s purpose in writing this text? To show us how serious the global warming is and arouse our greater awareness of environmental protection. (3)Why does the author mention the climate scientists’ warning? To give more supporting details. 2．Read the text fast and match the main idea with each paragraph. (　C　)(1)Para.1　　　 (　E　)(2)Para.2 (　A　)(3)Para.3 (　B　)(4)Para.4 (　D　)(5)Para.5 A．The causes of global warming. B．The results of global warming. C．Global warming and evidence. D．Suggestions. E．The dead polar bear. Task 2：Intensive reading Read the text carefully and fill in the blanks according to the text. Problem and evidence The warmer Earth results in a warming ocean and atmosphere, 1． melting ice and rising sea levels. And the dead polar bear is a case in point. Causes and effects ·The “natural” greenhouse effect guarantees to 2． sustain life on Earth by keeping Earth’s climate warm and 3． habitable ． Causes and effects ·The “man­made” greenhouse effect, caused by the burning of fossil fuels, leads to the rising temperature, extreme weather, natural disasters, deaths and economic 4． losses ． Measures ·People all over the world should be 5． aware of the problem. ·Governments should make 6． policies to reduce greenhouse gas emissions. ·We individuals can reduce our “carbon footprint” by 7． restricting the amount of carbon dioxide our lifestyles produce. Step 3　Post­reading—Critical Thinking Task 1：Discussion in groups Who do you think should take responsibility for dealing with climate change? What can we do? 答案略。 Task 2：理文化 温室效应 温室效应，又称“花房效应”，是大气效应的俗称。大气能使太阳短波辐射到达地面，但地表受热后向外放出的大量长波热辐射线却被大气吸收，这样就使地表与低层大气温度升高，因其作用类似于栽培农作物的温室，故名温室效应。自工业革命以来，人类向大气中排放的二氧化碳等吸热性强的温室气体逐年增加，大气的温室效应也随之增强，其引发的一系列问题已引起了世界各国的关注。 Task 3：学技巧 写作微技能——有关环境保护建议的高级句式 1．Climate scientists have warned that if we do not take appropriate actions，this warming trend will probably continue and there will be a higher price to pay. 2．Continued greenhouse gas emissions will result in further warming and long­lasting changes to the global climate. 3．Governments need to consider making policies and taking appropriate actions and measures to reduce greenhouse gas emissions. 4．We as individuals can also reduce our “carbon footprint” by restricting the amount of carbon dioxide our lifestyles produce. 5．It is our responsibility to seize every opportunity to educate everyone about global warming...
