According to the scientists who found its dead body，all that remained 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 to have starved③ and died.Experts claimed④ that low sea-ice 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 alarming case showed how the increase in temperature had an impact on⑤ Earth's ecology⑥. 句中who 引导定语从句，修饰先行词the scientists；that 引导定语从句，修饰先行词all，all that 相当于what。 句中that 引导宾语从句， 其中meant后又跟了一个省略了that 的宾语从句。 ③starve /stɑːv/ vi.& vt.(使)挨饿；饿死 ④claim vt.宣称；要求 ⑤have an impact on 对……有影响 ⑥ecology /i'kɒlədʒi/ n．生态；生态学 2013年，在挪威斯瓦尔巴群岛上发现了一只北极熊的尸体，这张新闻照片让很多人感到震惊。据发现北极熊尸体的科学家说，这只北极熊只剩下了“皮和骨头”。一位研究北极熊多年的专家说，从它尸体的位置看，这只北极熊似乎是饿死的。专家称，气候变化导致的低海冰水平意味着这只北极熊无法像以前那样捕猎海豹，所以它不得不长途跋涉去觅食。这一令人震惊的案例表明气温升高对地球生态产生了怎样的影响。 Then what is causing the increase in the global average surface temperature？Climate scientists often mention⑦ a key climate process called the “greenhouse effect”， which has two common meanings：the “natural” greenhouse effect and the “man-made” greenhouse effect. The “natural” greenhouse effect refers to⑧ the fact that heat from the sun enters the atmosphere and warms Earth's surface as short-wave radiation. The heat is released⑨ back into space at longer wave lengths.Greenhouse gases in the atmosphere，such as methane and carbon⑩ dioxide，trap some of the heat，keeping Earth's climate warm and habitable⑪.Without this process，Earth could not sustain⑫ life.However，the “man-made” greenhouse effect has now become a big problem.When people produce huge amounts of extra greenhouse gases by burning fossil fuels⑬， more heat energy is trapped in⑭ the atmosphere and causes Earth's surface temperature to rise quickly. 句中called the “greenhouse effect”为过去分词短语作后置定语；which 引导非限制性定语从句。 句中that 引导同位语从句。 此处keeping Earth's...是现在分词短语作结果状语。 ⑦mention vt.提到，谈到；提及，论及；说起 ⑧refer to 涉及；指的是 ⑨release /rɪ'liːs/ vt.& n．排放；释放；发布 ⑩carbon /'kɑːbən/ n．碳 carbon dioxide 二氧化碳 ⑪habitable /'hæbɪtəbl/ adj.适合居住的 ⑫sustain /sə'steɪn/ vt.维持；遭受；承受住 ⑬fuel /'fjuːəl/ n．燃料；刺激性言行 fossil fuel 化石燃料(如煤或石油) ⑭be trapped in 陷入……困境；被困于…… 那么是什么导致了全球表面平均温度的上升呢？气候科学家经常提到一个被称为“温室效应”的关键气候过程，它有两个常见的含义：“自然”温室效应和“人为”温室效应。“自然”温室效应指的是来自太阳的热量以短波辐射的形式进入大气层，使地球表面变暖。热量以更长的波长释放回太空。大气中的温室气体，如甲烷和二氧化碳，会捕获一些热量，使地球气候保持温暖并且适宜居住。没有这个过程，地球就无法维系生命。然而，“人为”温室效应现在已经成为一个大问题。当人类由于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，导致地表温度迅速上升。 There is strong and comprehensive⑮evidence that 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 actions⑯， this warming trend⑰ will probably continue and there will be a higher price to pay.In fact，news reports are frequently⑱broadcast⑲ about extreme rainstorms and heatwaves causing deaths and economic losses. 句中that 引导同位语从句；not only...but also...连接两个作结果状语的现在分词短语。 ⑮comprehensive /ˌkɒmprɪ'hensɪv/adj.全部的；所有的；详尽的 ⑯take appropriate actions 采取适当的行动 ⑰trend /trend/ n．趋势；趋向；动向 ⑱frequently /'friːkwəntli/ adv.频繁地；经常 ⑲broadcast /'brɔːdkɑːst/ vt.& vi.播送；广播；传播 n．广播节目；电视节目 有充分和全面的证据表明，气温的上升已导致世界范围内极端天气和自然灾害的增加，不仅造成严重的破坏，而且是以人类的生命为代价的。气候科学家警告说，如果我们不采取适当的行动，这种变暖的趋势可能会继续下去，我们将付出更高的代价。事实上，新闻报道经常播送造成死亡和经济损失的极端暴雨和热浪。 Continued greenhouse gas emissions will result in⑳ further warming and long-lasting changes to the global climate.This requires the attention of people all over the world.Governments need to consider making policies㉑ and taking appropriate actions and measures to reduce greenhouse gas emissions.We as individuals㉒ can also reduce our “carbon footprint”by restricting㉓ the amount of carbon dioxide our lifestyles produce.It is our responsibility to seize㉔ every opportunity to educate everyone about global warming，along with its causes and impacts，because this is the most serious issue㉕ affecting all of us on this planet. So what will you do to help? 主句中it作形式主语，动词不定式短语为真正的主语；because 引导原因状语从句。 ⑳result in 导致，结果是 ㉑policy /'pɒləsi/ n．政策；方针；原则 ㉒individual n．个人，个体 ㉓restrict /rɪ'strɪkt/ vt.限制；限定；束缚 ㉔seize /siːz/ vt.抓住；夺取；控制 ㉕issue n．问题 持续的温室气体排放将导致全球气候的进一步变暖和长期变化。这需要全世界人民的关注。各国政府需要考虑制定政策并采取适当的行动和措施来减少温室气体排放。作为个人，我们也可以通过限制生活方式所产生的二氧化碳排放量来减少我们的“碳足迹”。抓住每个机会来教育大家了解全球变暖及其原因和影响的知识是我们的责任，因为这是影响地球上所有人的最严重的问题。那么你会做些什么来助力呢？ Part 3　语篇研析 1．What is the main idea of the text?

Sarikhani spent three days looking for polar bears but without success as they were trapped in a thick fog.But then, as the ship came across some sea ice, she saw two polar bears.She and her team tracked them for eight hours.And under the light of the midnight sun, the bear clawed out a bed on a small iceberg before sleeping. The photograph inspires strong emotions in all its viewers.While climate change is the biggest challenge for humans, the photograph also inspires hope that there is still time to fix the mess we have caused. Polar bears are known to dig themselves spots to sleep in, which are sometimes referred to as “day bed”．They're also known to take one-　to two-hour-long sleeps, especially after a good meal. According to the museum, the area where the polar bear was taken on film is among the most isolated (孤立的) in the world, and holds a population of 19 polar bears that rely on the sea ice to travel and hunt offshore.But air temperatures in Svalbard have increased by 3℃ to 5℃over the past 40 to 50 years, which has resulted in heavy winter rainfall and some areas being ice-free most of the year.While the bears that follow sea ice may still be able to hunt year-round, this is increasingly over deeper waters, which may be less productive. Less sea ice for polar bears to use as a way to safely travel has also led to the animals having less genetic (基因的) diversity.There aren't as many opportunities for different groups to mix.This is leading to increased inbreeding among local bears. At present, Svalbard's polar bear population is still considered to be stable, but as global temperatures continue to increase, that may not be the case for long. [语篇解读]　本文是一篇新闻报道。世界上最负盛名的野生动物摄影奖之一的获奖照片是一只迷人又可爱的北极熊，由此引发了人们对于保护北极熊和关注气候变暖的共鸣。 2 3 1 4 1．What made it difficult for Sarikhani to spot polar bears in the beginning? A．The outdated equipment. B．The terrible weather. C．The lack of support. D．The tight schedule. 答案：B 细节理解题。根据第二段中的“Sarikhani spent three days looking for polar bears but without success as they were trapped in a thick fog.”可知，糟糕的天气状况使Sarikhani发现北极熊的工作变得非常困难。故选B。 2 3 1 4 2．What poses a risk to polar bears in Svalbard? A．The loss of sea ice. B．The extremely low temperature. C．The isolated position. D．The increase in genetic diversity. 答案：A 2 3 1 4 推理判断题。根据第五段中的“According to the museum, the area where the polar bear was taken on film is among the most isolated in the world...that rely on the sea ice to travel and hunt offshore.But air temperatures in Svalbard have increased by 3℃ to 5℃over the past 40 to 50 years, which has resulted in heavy winter rainfall and some areas being ice-free most of the year.”可知，北极熊依靠海冰在海上行走和捕猎， 但是随着气温上升，海冰减少，它们捕猎的成果可能会减少。也就是说，海冰的减少会对北极熊造成威胁。故选A。 2 3 1 4 3．What is the author's attitude to the future of Svalbard's polar bears? A．Uncaring.　　　　　　 B．Worried. C．Unclear. D．Optimistic. 答案：B 2 3 1 4 观点态度题。根据最后一段的内容可推知，作者担忧该地区的北极熊。故选B。 2 3 1 4 4．What is the best title for the text? A．Norway's Svalbard Archipelago B．The Biggest Challenge for Polar Bears C．An Award-Winning Photo “Ice Bed” D．The Reduction in Polar Bear Population 答案：C 2 3 1 4 标题归纳题。根据第一段的内容并结合文章主要说明了世界上最负盛名的野生动物摄影奖之一的获奖照片是一只迷人又可爱的北极熊，由此引发了人们对于保护北极熊和关注气候变暖的共鸣可知，C项最适合作为文章标题。故选C。 2 3 1 4 B The Amazon rainforest is as undisturbed a place as most people can imagine, but even there, the effects of a changing climate are playing out.Now, research suggests that many of the region's most sensitive bird species are starting to evolve in response to warming. Birds are often considered sentinel (哨兵) species—meaning that they indicate the overall health of an ecosystem—so scientists are particularly interested in how they're responding to climate change.In general, the news has not been good.For instance, a 2019 report by the National Audubon Society found that more than two-thirds of North America's bird species will be in danger of extinction by 2100 if warming trends continue on their current course. For the new study, researchers have collected the biggest data set so far on the Amazon's resident birds, representing 77 non-migratory species and lasting the 40 years from 1979 to 2019.During the study period, the average temperature in the region rose, while the amount of rainfall declined, making for a hotter, dryer climate overall.According to the report on November 12 in the journal Science Advances, 36 species have lost substantial weight, as much as 2 percent of their body weight per decade since 1980.Meanwhile, all the species showed some decrease in average body mass, while a third grew longer wings. Because of the study's long time series and large sample sizes, the authors were able to show the morphological (形态学的) effects of climate change on resident birds.However, the researchers themselves are unsure and wonder what advantage the wing length changes give the birds, but suppose smaller birds may have an easier time keeping cool.In general, smaller animals have a larger rate of surface area to body sizes, so they dissipate more heat faster than a bigger animal.Less available food, such as fruit or insects, in dryer weather might lead to smaller body sizes. [语篇解读]　本文是一篇说明文。文章主要介绍了气候变化对鸟类的影响。 5 6 7 8 5．Why are scientists fond of doing research on birds? A．They have small body sizes. B．They are sensitive to hot weather. C.They live in an undisturbed rainforest. D．They are ecological balance indicators. 答案：D 细节理解题。根据第二段中的“Birds are often considered sentinel species—meaning that they indicate the overall health of an ecosystem—so scientists are particularly interested in how they're responding to climate change.”可知，科学家喜欢研究鸟是因为鸟是生态系统平衡的暗示者。故选D。 5 6 7 8 6．What can we learn from the new study? A．A third of species have been extinct for a decade. B．36 species lost 2% of their body weight every year. C．Two-thirds of species showed a considerable decrease in weight. D．About 26 species responded to climate change with longer wings. 答案：D 5 6 7 8 细节理解题。根据第三段中的“For the new study, researchers have collected the biggest data set..., representing 77 non-migratory species and ...”以及“Meanwhile, all the species showed some decrease in average body mass，while a third grew longer wings.”可知，在研究的77种不迁移的鸟类中，1/3的鸟长着较长的翅膀。所以，大约26种鸟类长着较长的翅膀来应对气候变化。故选D。 5 6 7 8 7．What does the underlined word “dissipate” in the last paragraph mean? A．Put off. B．Give off. C．Put away. D．Give away. 答案：B 5 6 7 8 词义猜测题。根据最后一段中的“However, the researchers themselves are unsure and wonder what advantage the wing length changes give the birds, but suppose smaller birds may have an easier time keeping cool.In general, smaller animals have a larger rate of surface area to body sizes (然而，研究人员自己也不确定，他们想知道翅膀长度的变化给鸟类带来了什么好处，但假设体型较小的鸟类可能更容易保持凉爽。一般来说，相对于身体尺寸而言，较小的动物的表面积较大)”可知，较小动物的表面积相对于自身整体而言较大，因此散发热量就容易，dissipate的意思是“散发”，与Give off (散发)的词义一致。故选B。 5 6 7 8 8．What would probably the researchers further study? A．Why it is easier for smaller animals to keep cool. B．What effects the wing length changes have on birds. C．Why the Amazonian birds have lost substantial weight. D．Whether bird species in North America will be extinct in 2100. 答案：B 5 6 7 8 推理判断题。根据最后一段中的“However, the researchers themselves are unsure and wonder what advantage the wing length changes give the birds...”可知，研究者将进一步研究鸟类的翅膀长度变化对鸟类有什么影响。故选B。 5 6 7 8 Ⅱ.阅读七选五 [语篇解读]　本文是一篇说明文。文章讲述了图瓦卢因气候的改变长期以来一直受到海平面上升的威胁，面临着国家消失的危险。该国家计划在网上建造虚拟世界。文章分析了其中的优势和弊端，也以此呼吁人们更好地保护现实世界。 1 2 3 4 Building a country is never easy.It takes hard work from generation to generation. 1 A new report from The Guardian said long time of climate change can do that.The report said Tuvalu will be the first country to be completely lost due to climate change. 5 1 2 3 4 A.But how about destroying it?
