In recent years, the people of these islands have noticed tides getting higher and storms getting worse. And they wonder—is their world about to change? Sadly, the fact is that the islands in the Pacific, especially low-lying coral ones,are suffering the serious effects of global warming. low-lying (土地 )低的；低洼的 As global temperatures increase, so do sea levels. Increasing temperatures cause ice sheets and glaciers at the North and South Poles to melt, releasing additional water into the ocean. Warm water also takes up more room than cool water, so as the ocean warms,sea levels rise further. Scientists expect sea levels worldwide may rise by 0.6 to 1.3 metres or more by 2100 if the planet continues to warm. ice sheet(术语)冰原；冰盖 On the Pacific Islands, the most obvious sign of rising sea levels is that at high tide, water moves further inland to flow into houses and over roads. In fact, beaches or even whole islands are disappearing: five of the Solomon Islands have already vanished beneath the waves since 1947! Increasing sea levels also contaminate the islands’ freshwater supplies.涨潮时海水涌入更多内陆地区,流入房屋,漫过道路。 high tide(海的)高潮时期,高潮,满潮;涨潮 in·land adv.向(或在)内陆;向(或在)内地 adj.(在)内陆的；(在)内地的 Solo·mon  /ˈsɒləmən/ 所罗门 fresh·water淡水(的) When salty seawater seeps through the ground and gets into wells, the water becomes useless for drinking and irrigation. Besides, growing sea levels interfere with some islands’ natural reshaping processes. Usually, waves gradually remove sand from one side of an island and dump new sand on the other side. 当含有盐分的海水渗入地下、进入水井时，其中的水就无法用于饮用和灌溉。此外，不断上升的海平面还会干扰一些岛屿的自然重塑过程。通常，海浪会逐渐将沙子从岛屿的一侧带走，并将新的沙子堆在另外一侧。 interfere with sth.妨碍;干扰;弄坏(器材等) re·shape /ˌriːˈʃeɪp/ 改变…的形状(或结构);重塑;改组 Unfortunately, however, rising waves accelerate the process,and this certainly causes problems for anyone living on the side that is being washed away. Meanwhile, increasing global temperatures can have disastrous consequences in other ways. Extreme temperatures generate extreme rainfall patterns. Consequently, the islands go without life-sustaining rainfall for months, leading to crop failure and reduced freshwater reserves. 这些岛屿数月没有能让生命得以维持的降雨,导致农作物歉收,淡水储量减少。 go without (sth)没有…而勉强应付；没有…也行 Then suddenly too much comes at once, and precious soil and homes are washed away by the floods. For example, on the hilly Cook Islands, storms have given rise to landslides that carry islanders’ homes down the hillsides. Additionally,the annual tropical cyclones are becoming stronger and happening more frequently,resulting in more severe flooding and landslides.然后突然下了太多的雨，宝贵的土壤和家园被洪水冲走。例如，在多山的库克群岛，暴风雨引发了山体滑坡，将岛上居民的房屋冲下山坡。此外，每年的热带气旋变得越来越强，发生得越来越频繁，导致更严重的洪水和山体滑坡。 land·slide/land·fall (山坡或悬崖的)崩塌,塌方,滑坡,地滑 What is more, as the ocean warms,many coral reefs, which act as natural barriers and are home to a rich diversity of ocean species, are dying. Heat and extra carbon dioxide in the atmosphere hurt the corals that build the reefs. Without healthy reefs, fish move away, and the islanders have less to eat.更重要的是，随着海洋变暖，许多珊瑚礁正在死亡，它们本来是天然的安全屏障，是各种各样的海洋生物栖息的家园。高温和大气中过多的二氧化碳会对建造珊瑚礁的珊瑚虫产生不利影响。没有健康的珊瑚礁，鱼类会离开，岛民的食物就会减少。 act as/like sth充当；起作用 hurt对…有不良影响,have a bad effect on sb/sth Despite the challenges, the islanders are not giving up without a fight. For many island communities, fighting climate change is not a choice; it is a matter of survival. They are working with scientists and learning to protect their homes from flooding and storm surges by building sea walls from old bits of coral reefs.尽管面临挑战，岛上的居民们却并没有不战而降。对许多岛上的社区来说，应对气候变化不是一件可以选择做或不做的事情，而是一个关乎生存的问题。他们正与科学家合作，学习利用以往的珊瑚礁碎片建造海堤，以保护他们的家园免受洪水和风暴潮的侵袭。 fight应对 ,极力反对,与…作斗争 sea wall海堤；防波堤 surge(风、水等) 突然的涌动 bit 小块儿 They are cutting down fewer trees, since trees hold onto soil. They are also planting mangrove trees to protect the coastal areas. To keep the damaging salt away from their crops, they are growing crops in containers. They are looking for crops that do not mind salty water. Hopefully, they can find a way to stay on their islands, at least for a while.他们正减少砍伐树木，因为树木能保持土壤。他们还种植着红树林来保护沿海地区。为了让有害盐分远离他们的作物，他们将作物种植在容器中。他们正在寻找可以适应咸水的作物。希望他们能找到留在岛上的办法，哪怕只是多留一段时间。 keep sb/sth away (from sb/sth)不让接近某人(或某事物);使离开 However, some islanders have made a life-changing decision—moving away from the ocean. It is by no means easy as the ocean has been part of their lives for generations. An entire village on the island of Vanua Levu in Fiji abandoned their coastal homes to move up into the hills. Fortunately, they could begin a new life: buying land, building new houses and growing pineapples.然而，一些岛民已经做出了改变人生的决定——搬离海洋。这绝非易事，因为世世代代以来海洋都是他们生活的一部分。在斐济的瓦努阿岛上，全村人放弃了他们海边的家园，搬到了山上。幸运的是，他们可以开始新的生活：购买土地，建造新房屋，种植菠萝。 Vanua Levu /vɑːˌnuːə ˈlevuː/瓦努阿岛 Fiji /ˈfiːdʒiː/斐济 Some miss their old life by the sea, but at least the hills provide refuge from the rising sea, and they are still together. Many of those whose islands have no hills are looking for homes on new islands, or even in new countries. Most do not want to leave, but with the ocean moving in, they feel they have no choice. 有些人怀念过去在海边的生活，但至少群山为他们提供了躲避上涨海水的避难所，而且他们仍然住在一起。许多岛屿上没有山，那里的人们正在新的岛屿上，甚至在新的国家里寻找栖身之所。大多数人并不想离开，但随着海水的涌入，他们觉得自己别无选择。 move in (on sb/sth)从四面八方逼近；进逼 No matter what solutions the islanders develop, their islands are still in hot water. Global warming requires not only islanders to fight back. After all, we are living in a human community with a shared future. Maybe we can take a lesson from the ocean. Melting ice in the Arctic makes higher waves in Fiji because all the oceans are connected—there are no walls between them. 无论岛民们制订出什么样的解决方案，他们的岛屿仍然处于水深火热的困境之中。全球变暖不仅需要岛民们起来反击。毕竟，我们生活在人类命运共同体中。也许我们可以从海洋中吸取教训。北极融化的冰层在斐济掀起了更高的波浪，因为所有的海洋都是相连的——它们之间没有隔墙。 fight back (against sb/sth)奋力抵抗；还击 Change one, change all. If we need to tackle the problem of climate change, we will have to work together as one. 一处改变，处处改变/牵一发而动全身。如果要解决气候变化问题，我们就必须团结一致。 A.Write a summary of the science magazine article. Use the following questions to help you. • What are the effects of global warming on the Pacific Islands? • What efforts are the islanders making to save their homes and lives? The islands in the Pacific Ocean are suffering from the serious effects of global warming. The rise in global temperatures causes sea levels to rise, resulting in high tide water moving further inland. Moreover, the rising sea interferes with some islands’ natural reshaping processes and creates problems for people who live on the side that is being washed away. Extreme temperatures create extreme rainfall patterns. Long droughts affect crops and freshwater supplies, followed by heavy rainfall that washes away soil and homes. Heat and extra carbon dioxide make many coral reefs disappear, removing natural barriers and an important food source.The islanders are not giving up against global warming without a fight. Some islanders have made the life-changing decision to move away from the ocean. Some move up into the hills, while others look for homes on new islands, or even in new countries. However, global warming concerns not only islanders as all the oceans are connected, so we must all work together to tackle the problem. B. What effects of global warming have you witnessed or read about? What could you do to help solve this problem? I read that global warming poses risks to the survival of animal species on land and in the ocean. As temperatures climb,animal habitats are threatened by forest fires,floods and melting ice. Habitat disruption damages ecosystems that have evolved for millennia but are unable to adapt to the sudden climate change. climb(温度、国家的货币等) 上升；增值；升值 mil·len·nium  /mɪˈleniəm/ ( pl.mil·len·nia/‑niə/ 一千年,千年期(尤指公元纪年) This leads to food shortages, among other things. Some species are able to relocate and survive,but others cannot. For example, the polar bear may be a strong swimmer, but as the ice continues to melt, it must swim further and further to locate its prey, which means its chances of finding food are reduced and it may starve. It has adapted to cold climates, so where will it go when all the ice is gone? among other things/places/factors除了其他东西/地方/因素 re·locate /ˌriːləʊˈkeɪt/(尤指公司或工人)(使)搬迁，迁移 locate/ləʊˈkeɪt/找到;确定…的准确地点 prey  /preɪ/猎物 Trying to reduce the impact of global warming on animal habitats may be an enormous personal goal, but every one of us can contribute to solving the problem.We can reduce our carbon footprint by only eating seasonal fruit and vegetables.We can ride a bike or walk more instead of calling a taxi. Volunteering for conservation activities in the community can also help. sea·son·al  /ˈsiːzənl/季节性的;随季节变化的;节令性的 Though these actions may appear small, with everyone’s involvement, many small actions, when added up,can have a meaningful impact. in·volve·ment (in/with sth)/ɪnˈvɒlvmənt/ 参与;加入;插手,=participation;耗费时间;投入;沉迷 add (sth.) up把…加起来;积少成多;(尤用于否定句 ) 合乎情理；有道理 Read the title again and analyse the rhetorical device used in the title. The author uses a pun in the title. A pun refers to the clever or humorous use of a word or phrase that has more than one meaning, or of words that have different meanings but sound the same. Here “in hot water” creates the image that the islands are being flooded by warmer and rising sea water caused by the climbing temperatures of the Earth and suggests that the islanders are suffering a lot. Not only does it make the language vivid, but also evokes readers’ concern for the problem. Read paragraph 1 and analyse the rhetorical device used in the following sentence. And they wonder—is their world about to change? This is a rhetorical question. A rhetorical question is a question that requires no reply, either because the answer is obvious or because the person asking the question already knows the answer. Rhetorical questions are generally used to persuade readers, make them think or direct their attention to an important topic.In the above sentence, the author uses the rhetorical question to attract readers’ attention and lead them to think about the problem of climate change. $
