A warming ocean and atmosphere along with① melting② ice and rising sea levels③ provide evidence of a dramatic change in the global climate. ❶“There is little doubt that ...”意为“几乎毫无疑问……”，that引导同位语从句。 In 2013，a lot of people were shocked by④ a news photo of a dead polar bear ❷that was found on Norway's Arctic island of Svalbard．According to⑤ the scientists who found its dead body，all ❸that remained⑥ of the polar bear was “skin and bones”．An expert who has studied polar bears for many years said that from the position of its dead body，the bear appeared ❹to have starved⑦ and died．Experts claimed⑧ that low sea­ice levels caused by climate change meant the bear could not hunt seals⑨ as before，so it had to travel greater distances in order to⑩ find food.This alarming case showed how the increase in temperature had an impact on⑪ Earth's ecology. ❷that引导定语从句，先行词是a dead polar bear。 ❸all后接that引导的定语从句。 ❹appear后接不定式的完成式作表语。 Then what is causing the increase in the global average⑫ surface temperature? Climate scientists often mention a key climate process ❺called the “greenhouse effect⑬”， which has two common meanings: the “natural” greenhouse effect and the “man­made” greenhouse effect.The “natural” greenhouse effect refers to⑭ the fact ❻that heat from the sun enters the atmosphere and warms Earth's surface as short­wave radiation．The heat is released⑮ back into space at longer wave lengths.Greenhouse gases in the atmosphere，such as methane and carbon dioxide⑯，trap some of the heat，❼keeping Earth's climate warm and habitable⑰.❽Without this process，Earth could not sustain⑱ life.However，the “man­made” greenhouse effect has now become a big problem.When people produce huge amounts of⑲ extra greenhouse gases by burning fossil fuels⑳，more heat energy is trapped in the atmosphere and causes Earth's surface temperature to rise quickly. ❺过去分词短语作后置定语。 ❻that引导同位语从句。 ❼现在分词短语作状语。 ❽介词 without 可用于表示条件，引出虚拟语气，与 but for 大致同义，意为“若无；若非”，此处相当于If there were not this process。 There is strong and comprehensive evidence ❾that the rise in temperature has led to an increase in extreme weather and natural disasters worldwide，not only causing serious damage，but also costing human lives.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.In fact，news reports are frequently broadcast about extreme rainstorms and heatwaves causing deaths and economic losses. ❾that引导同位语从句。 that引导宾语从句，此处that虽然在从句中不作成分，但不能省略，因为其后还有一个if引导的条件状语从句。 Continued greenhouse gas emissions will result in further warming and long­lasting 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 individuals can also reduce our “carbon footprint” by restricting the amount of carbon dioxide our lifestyles produce． It is our responsibility to seize 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? 　　 “by＋动词­ing形式”作方式状语。 ◆难词注解 ①along with ...和……一起；连同……；除……以外(还)；与……同样地 ②melt vi.& vt.(使)融化；熔化；软化 ③sea level海平面 ④be shocked by/at对……感到震惊 ⑤according to按照；根据；依照 ⑥remain v．剩余；遗留 ⑦starve vi.& vt.(使)挨饿；饿死 ⑧claim v．断言；声称 ⑨seal n．海豹 ⑩in order to＝so as to 为了(但so as to 不能置于句首) ⑪have an impact on ... 对……有影响；对……造成影响 ⑫average adj.平均的；一般的；平常的 ⑬greenhouse effect温室效应 ⑭refer to查阅；参考；涉及；提到；谈起；指的是 ⑮release vt.& n．排放；释放；发布 ⑯carbon dioxide二氧化碳 ⑰habitable adj.适合居住的 ⑱sustain vt.维持；遭受；承受住 ⑲huge amounts of 大量的 ⑳fossil fuel化石燃料(如煤或石油) fuel n．燃料；刺激性言行 vt. & vi.(给……)提供燃料 be trapped in被困于 comprehensive adj.全部的；所有的；详尽的 lead to导致；造成；通向 worldwide adv.遍及全球地 adj.世界各地的；影响全世界的 not only ...but also ...不仅……而且…… warn v．警告；告诫 take appropriate actions采取适当的行动 trend n．趋势；趋向；动向 frequently adv.频繁地；经常 broadcast vt. & vi.(broadcast，broadcast)播送；广播；传播 n．广播节目；电视节目 result in导致 all over the world在全世界 consider doing sth.考虑做某事 make policies 制定政策 policy n．政策；方针；原则 footprint n．足迹；(某物所占的)空间量；面积 restrict vt.限制；限定；束缚 seize vt. 抓住；夺取；控制 参考译文 气候变化需要全世界的关注 我们了解气候变化已经有几十年了。几乎毫无疑问，地球正在变得越来越暖(见表)。海洋和气候变暖以及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，在挪威境内北冰洋上的斯瓦尔巴群岛发现一只死亡的北极熊，北极熊尸体的新闻照片震惊了很多人。根据发现北极熊尸体的科学家的说法，这只北极熊只剩下“皮肤和骨头”了。一位研究北极熊多年的专家说，从尸体状况来看，这只北极熊似乎是饿死的。专家声称，由于气候变化导致海冰平面下降，这只北极熊无法像以前那样捕猎海豹，因此它为了找到食物，不得不走更远的距离。这个令人惊恐的案例展示了温度升高如何影响了地球的生态。 那么，是什么导致全球平均表面温度上升呢？气候科学家经常提到一个被称为“温室效应”的重要气候过程，它有两个普遍的含义：“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层并使地球表面变暖。热量以更长的波长释放回太空。大气层中的温室气体如甲烷和二氧化碳，吸收了部分热量，使地球的气候温暖宜居。没有这个过程，地球将无法维系生命。然而，“人为”温室效应现在已经成为一个大问题。当人们燃烧化石燃料产生大量额外的温室气体时，更多的热能被留存在大气层中，导致地表温度迅速上升。 有充分而全面的证据表明，温度升高导致全世界范围内极端天气和自然灾害增加，不仅造成了严重的破坏，而且还致人丧命。气候科学家警告说，如果我们不采取适当的行动，这种变暖趋势可能会持续下去，并将使我们付出更高的代价。事实上，有关极端暴风雨和热浪造成死亡和经济损失的新闻报道已屡见不鲜。 温室气体的持续排放将导致全球气候进一步变暖，并带来持久的变化。这需要全世界人们的关注。政府需要考虑制定政策并采取适当的行动和措施以减少温室气体排放。作为个人，我们也可以通过限制我们的生活方式产生的二氧化碳的量来减少我们的“碳足迹”。我们有责任抓住每一个机会，让每个人了解全球变暖及其成因和影响，因为这是影响这个星球上我们所有人的最严重的问题。那么你将做什么来提供帮助呢？ Ⅱ.文本理解 ►主旨大意 The passage is mainly about climate_change_and_environment_protection． ►文章架构 ►主旨匹配 (　　)Para.1　A．The reasons causing the increase in temperature.
