W：My pleasure. run out of Step Ⅲ　Post listening 听力技法——熟悉地点与去向表达 听力中经常有关于判断地点、描述路径的语篇，做好此类题目的关键是抓取场景词汇，并熟悉相应表达。 技巧点拨 1．描述东西的位置。 描述“某物在哪里时”，地点提示词很关键，如 there they are，there it is，here it is 等，后面通常是正确的地点。 2．根据上下文理清地点副词 there 或 here 所指代的地点。如When the class is over，I need to go to the lab first，and then I'll be at the cafeteria at about twelve thirty.Let's meet there.句中的there指代at the cafeteria。 3．利用关键词推断地点。如根据see off，catch a flight等可以判断是去机场。根据deliver a package，drop a letter off可以判断是去邮局。 4．掌握问路或者引路的各种方位词。如在旁边next to，beside，close to；在对面across from，opposite；在前面in front of；在左手边on your left-hand side。 典题示例 听力原文 M：I can't find my pen anywhere.It was on the desk with my book a moment ago. W：Look，here it is.You left it on the sofa. 听力试题 Where is the pen？ A．On the sofa.　　　 B．On the desk. C．Beside the book. 策略应用　根据关键词here it is以及left it on the sofa可以判断钢笔在沙发上，故选A。 返回 语基讲练　提能力 返回 归 纳 Ⅰ. 核心词汇练全 trap vt.困住；使陷于危险中 (1)be trapped in... 被困在……中 trap sb into doing sth 诱骗某人做某事 (2)trap n.

Now aged 73，he still teaches a course named“Protection and Restoration of Ancient Chinese Buildings” at a University in Shanxi Province.His main interest is Dougong，a building method that uses closely connected wooden pieces to form structures.The method is one of the most important features of ancient Chinese buildings. Wang also started online classes to better explain Dougong to those who showed a strong interest in his course.Following a suggestion from his students，he became a vlogger using the account name“Dougong class”．The account is regularly updated with short video clips Wang produces himself.He is surprised that his classes are so popular on social media.The first six lectures on ancient Chinese buildings that he uploaded over a six-month period have received 1.6 million views. To make it easier for newcomers to the subject to understand，Wang made a wooden Dougong model.Each part is marked with a number or name，and the model can be taken apart and put together，a process that Wang filmed and put online.Some viewers said that they had long been puzzled by Dougong structures，but finally understood how they work after watching the video of “Dougong grandpa”． Wang said when he was young，the beautiful ancient structures in his hometown had ignited his interest in ancient wooden buildings and finally led him to turn his interest into a lifelong career.What makes him happy today is not only that the government set aside more money for the research and protection of cultural relics，but also that society is more aware of the importance of such work. To his surprise，about 90 percent of his more than 100，000 viewers online are below age 30.That fact makes him more confident that as long as the story of ancient Chinese architecture is told in the right way，it can attract more people. 语篇解读　本文是一篇新闻报道。文章报道了文物保护者王永先退休后通过教学保持对中国古建筑的热爱，并在网络上开设斗拱课程，让大家明白了斗拱的工作原理。 1．What can we learn from the first two paragraphs？ A．Dougong is a well-protected Chinese building structure.

B．Widened. C．Started. D．Changed. √ 词义猜测题。根据画线词所在句句意可知，王永先在叙述自己如何对古代木结构建筑产生兴趣，继而从事该事业的过程。由此推知，家乡美丽的古代建筑引发了他的兴趣，画线词意思应该与 start“开启，启动”一致。故选 C。 B (2025·浙江北斗星盟高一期中) A Portland，Oregon man has become the first person to travel across Antarctica alone without any assistance. Colin O'Brady has completed the 1，500-kilometre trip.He crossed the polar continent in 54 days.Friends，family and other people followed his progress through messages and pictures he left on social media. O'Brady spoke with his wife Jenna Besaw by telephone soon after he completed the journey.“It was an emotional call，” she said.“He seemed overwhelmed by love and appreciation，and he really wanted to say ‘thank you’ to all of us.” O'Brady recorded the trip on the social networking sites.He called his journey“The Impossible First”．He wrote that he travelled the last 129 kilometres in one big，final push to the finish line that took well over an entire day.O'Brady wrote，“While the last 32 hours were some of the most challenging hours of my life，they have quite honestly been some of the best moments I have ever experienced.” The day before，he posted that he was “in the zone” and thought he could make it to the end in one go.“I was listening to my body and taking care of the details to keep myself safe，”he wrote.“I called home and talked to my mum，sister and wife.I promised them I would stop when I need to.” Though other people have travelled across Antarctica，they had either assistance with more plentiful supplies or devices that helped move them forward. In 2016，British explorer Henry Worsley died in his attempt to travel alone across Antarctica unassisted.Worsley's friend Louis Rudd，also from Britain，attempted an unaided solo journey in Worsley's honour.He was competing against O'Brady to be the first to do it.Besaw said her husband planned to stay in Antarctica until Rudd finished his trip. 语篇解读　本文是一篇新闻报道。文章报道了科林·奥布雷迪穿越南极洲时遇到的困难和克服困难的过程。 5．What did O'Brady think of his journey through Antarctica？ A．It was pleasant.

B．Trying to achieve the goal. C．Keeping in touch with them. D．Stopping the travel halfway. √ 细节理解题。根据第五段中的“I called home and talked to my mum，sister and wife.I promised them I would stop when I need to.”可知，奥布雷迪答应家人自己会注意安全。 7．Why does O'Brady still remain in Antarctica？ A．To wait for another explorer. B．To compete with others. C．To help other explorers. D．To make his victory recognised. √ 细节理解题。根据最后一段最后一句可知，奥布雷迪仍然留在南极洲没回来是在等待另一个探险者拉德。 8．What might be a suitable title for the text？ A．The Antarctic Continent B．Completing “The Impossible First” C．Travelling Through Antarctica D．An Incomplete Journey √ 标题归纳题。文章第一段点明主旨：一名男子成为第一个在没有得到任何帮助的情况下独自穿越南极洲的人；下文讲述了他穿越南极洲时遇到的困难和克服困难的过程。故B项最适合作文章标题。 Ⅳ.阅读七选五(共5小题；每小题2.5分，满分12.5分) (2025·山东青岛高一期中) Thanks to Earth，we have fresh air to breathe，clean water to drink and warm sunshine to enjoy.But it seems that we may have taken these things for granted and not realised that our planet is getting“sick”.1( ) More than 15，000 researchers around the world have written a letter to warn about environmental threats.

Among those environmental challenges，global warming sits at the top.Global average temperatures have risen by more than 0.5℃ since 1992. 　＿＿＿＿＿＿＿＿＿＿＿＿＿　It means that heat waves would last around a third longer and rainstorms would be about a third more intense (猛烈的) if we take no action.The increase in sea levels would also be much higher.Countries like Singapore and Japan that are at low altitudes may be covered by the ocean in the future. A．The change is a big deal. 根据空处前 “Global average temperatures have risen by more than 0.5℃since 1992.”可知，此处强调的是全球平均气温的变化。再根据下文及其中关键词 longer、 more intense、 much higher 表明的一系列严重后果可知，A 项(这种变化是一件大事。)承上启下，其中的 The change 与上文的“气温变化”相呼应，符合语境。 ＿＿＿＿＿＿＿＿＿＿＿＿＿＿＿＿＿＿＿＿＿＿ It's getting harder to get fresh water.Ocean pollution has become serious.Since 1992，the human population has grown by 2 billion，while the populations of all other animals have dropped by nearly 30 percent. 根据上文的 “Countries like Singapore and Japan that are at low altitudes may be covered by the ocean in the future.”以及空后的 “It's getting harder to get fresh water.Ocean pollution has become serious.”可知，此处讲述了人类面临的另一个环境挑战，即海洋污染变得严重，淡水越来越难以获得。空处位于段首，C项(但这并不是人们面临的唯一问题。)引出了下文内容，符合语境。 C．But this is not the only problem people are facing. Scientists say that we are experiencing the sixth mass extinction(大量灭绝) in history.More than two-thirds of the world's wildlife could be gone by the end of the decade if action isn't taken soon. ＿＿＿＿＿＿＿＿＿＿＿＿＿＿＿＿＿＿＿＿＿＿＿＿＿＿＿＿＿＿＿＿＿＿ 根据上文的 “More than two-thirds of the world's wildlife could be gone by the end of the decade if action isn't taken soon.”可知，如果不尽快采取行动，全球超过三分之二的野生动物可能会消失。F项(一些稀有动物，如黑犀牛，很快可能只会在照片中出现。)承接上文，说明黑犀牛可能会受到环境影响，即将消失，might just appear in pictures 呼应上文中的extinction 和could be gone。 　　　　　　　　　　　　　　　　F．Some rare animals，like black rhinos，might just appear in pictures soon. However，we have made some progress.That‘s because we gradually stopped using chemicals that can break down ozone，a gas that protects Earth.＿＿＿＿＿＿＿＿＿＿＿＿＿＿＿＿＿＿＿＿＿＿＿＿＿＿ 根据上文 “However，we have made some progress.That's because we gradually stopped using chemicals that can break down ozone，a gas that protects Earth.”可知，人类在环境保护方面已经取得了一些进展。D项(如果我们立刻采取行动，我们就能产生更大的影响。)承接上文，表明如果人类现在采取行动，就能产生更多积极的影响。 D．We can make a bigger difference when we act right now. 返回 谢 谢 观 看 UNIT 5　 HUMANS AND NATURE 返回 $
