Unit 6　At one with nature ●Ⅰ 【文章大意】 这是一篇说明文。文章主要说明了枯树支持物种和维持生物多样性,介绍了枯树中存在的生命形式。 1.C　细节理解题。根据第一段“At first glance, a dead tree might just look like a lifeless, fallen log. But look closer: beneath the rotting bark (树皮), the wood is full of life. Upon its death, the tree’s tightly sealed tube system, previously used to transport nutrients and water, becomes empty and allows some creatures to pass through, according to Matteo Garbelotto, a professor at the University of California, Berkeley.”(乍一看,一棵枯树可能只是看起来像一根没有生命的倒下的原木。但仔细看,在腐烂的树皮下,木头充满了生命。加州大学伯克利分校的Matteo Garbelotto教授说,在树死后,以前用于运输营养物质和水的紧密密封的管道系统变得空了,允许一些生物通过。)可知,枯树的主要功能是支持物种和维持生物多样性。故选C。 2.D　词义猜测题。根据画线词上文“These empty trunks, still standing upright, are also called snags or wildlife trees.”(这些仍然直立的空树干也被称为枯立木或野生动物树。)以及后文“…they can host a high diversity of species that varies from top to bottom.”可知,枯树可以容纳高度多样性的物种,且这些物种从树干顶部到底部各不相同,这是因为它们处于直立姿态。故画线词的意思是“树的直立姿态”。故选D。 3.D　细节理解题。根据第三段“Fungi do much of the hard work of speeding up the decomposition process, softening the hard trunk into something with many small holes.”(真菌在加速分解过程中做了很多艰苦的工作,把坚硬的树干软化成有许多小孔的东西。)可知,真菌加速了枯树的分解。故选D。 4.A　主旨大意题。根据第一段“At first glance, a dead tree might just look like a lifeless, fallen log. But look closer: beneath the rotting bark (树皮), the wood is full of life.”并结合文章主要说明了枯树可以支持物种和维持生物多样性,介绍了枯树中存在的生命形式可知,A选项“枯树的来世”最适合做文章标题。故选A。 ●Ⅱ 【文章大意】 本文是一篇说明文。文章介绍了下雪后世界变得安静的原因。 1.B　上文“Have you ever noticed how peaceful the world seems after a good snowfall and how quiet the landscape becomes whenever it snows?”提出下雪后世界变安静这一现象并引发思考。B选项(这不是你的头脑在捉弄你。)承接上文,表明下雪后世界确实会变安静,并非大脑捉弄人们,让人们产生错觉,上下文语意衔接自然。故选B。 2.C　上文“Some of the newfound quiet after a snowfall is logical. People tend to stay home during snowstorms, which means there are fewer people outside and not as many cars on the road. And birds tend to stay in their nests during severe weather, so they are quieter during a snowstorm too, according to the National Audubon Society.”从人、鸟活动方面说明了下雪后安静的原因。C选项(但这种安静背后也有科学原理。)引出下文从科学角度解释雪能吸收声音这一原因,与上文构成递进关系,选项C中science与下文的科学解释“Snow absorbs sound, so when a fresh blanket of snow covers the landscape, it absorbs many of the sound waves, making it seem quieter outside, according to AccuWeather.”相照应。故选C。 3.D　上文“The sound absorption rating of snow falls somewhere between 0.5 and 0.9.”说明了雪的吸音率情况。D选项(这意味着它能吸收大部分周围的声音。)对上文雪的吸音率情况进行总结,表明雪能吸收大部分声音,选项中that指代上文雪的吸音率情况。故选D。 4.E　下文“Usually a few inches of snow is needed to have a noticeable quieting effect…”说明了要有明显安静效果所需雪的厚度。E选项(仅仅薄薄一层雪不足以吸收很多声音。)与下文相呼应,说明少量雪不能很好地吸收声音,需要一定厚度的雪才行,上下文逻辑连贯。故选E。 5.A　下文“The reason? The snowflakes change shape as they melt (融化), reducing the size of the spaces between the crystals. As temperatures fluctuate (波动) in winter, newly fallen snow can partially melt and then freeze. Once the snow turns into ice, it can actually increase nearby sounds because ice reflects sound waves rather than absorbing them.”解释了雪融化后失去吸音能力的原因。A选项(随着雪融化,它会失去吸音能力。)引出下文对雪融化后情况的说明,上下文逻辑合理。故选A。 ●Ⅲ 【文章大意】 这是一篇新闻报道。文章主要介绍了粤港澳大湾区作为全球生物多样性热点地区,通过举办生物多样性摄影展,向公众展示其独特的自然景观和珍稀野生动植物,旨在提高人们的环保意识,促进人与自然更深层次的联系,并展现环境保护与区域发展成功融合的典范,为城市发展与生物多样性保护和谐共进提供了示范路径。 1.striking　考查形容词。此处修饰名词landscapes,应用形容词striking“引人注目的”,作定语。故填striking。 2.to appreciate　考查非谓语动词。此处为固定搭配allow sb to do sth“让某人做某事”,动词不定式作宾语补足语。故填to appreciate。 3.a　考查冠词。此处泛指“一次展示”,且display的发音以辅音音素开头,应用不定冠词 a。故填a。 4.photographers　考查名词复数。此处与conservationists是并列成分,表示“摄影师”,应用名词photographer,使用复数形式,表泛指。故填photographers。 5.sought　考查动词时态。句子描述的是过去发生的事情,应用一般过去时,seek的过去式是sought。故填sought。 6.hidden　考查非谓语动词。hide与wonders之间是被动关系,即“奇观被隐藏”,应用过去分词hidden,作定语。故填hidden。 7.to　考查介词。固定搭配from…to…意为“从……到……”,to是介词。故填to。 8.experiencing　考查非谓语动词。visitors与experience之间是主动关系,应用现在分词,作状语。故填experiencing。 9.integration　考查名词。此处作demonstrated的宾语,应用名词integration“融合”。故填integration。 10.where　考查定语从句。此处引导限制性定语从句,先行词是path,表示地点,关系词在从句中作地点状语,应用关系副词where引导。故填where。 ●Ⅳ 【思路点拨】 本文以人物为线索展开,讲述了热爱动物和自然的生物系学生Emma与经验丰富的徒步旅行者Jack在探索家乡附近的森林时,听到动物的求救声,发现一只被困在灌木丛中腿部被藤蔓缠住的小鹿,并对其展开救助的故事。 【详解】 1. 段落续写: ①由第一段首句内容“‘等等,’Emma说。‘它的腿受伤了。’”可知,第一段可描写Emma发现小鹿受伤后的救助行动。从Emma指出小鹿受伤,到拿出急救箱为其清理伤口、上药、包扎,突出救助过程。 ②由第二段首句内容“经过紧张的几分钟后,Jack终于设法松开了小鹿的腿。”可知,第二段可描写Jack成功解救小鹿的腿后,小鹿的反应以及Emma和Jack的对话与感受,包括小鹿离开,Emma担心其安危,Jack安慰她,体现两人对小鹿的牵挂和对此次经历的思考。 2. 续写线索:Emma发现小鹿受伤—拿出急救箱救助—救助过程—Jack解救小鹿的腿—小鹿离开—Emma担心—Jack安慰。 One possible version: “Wait,” Emma said. “Its leg was injured.” The deer was bleeding, with some small cuts on its right hind leg (with复合结构). “We should clean the cuts before they get infected (时间状语从句).” Emma reached for her backpack and took out the first-aid kit. She pulled out a small bottle of alcohol and a clean cloth. Jack paused and watched as Emma carefully cleaned the wounds with alcohol (时间状语从句). Then she applied some anti-inflammatory powder to them and bandaged them with the cloth. The deer flinched but remained still, its dark eyes locked on hers (独立主格结构). “It’s like it understands,” Jack said, his voice filled with awe (独立主格结构). After a few tense minutes, Jack finally managed to free the deer’s leg. The deer hesitated for a moment, looking at them with its large, dark eyes affectionately (现在分词短语作状语). Then, with a soft snort, it limped away into the forest, disappearing among the trees (现在分词短语作状语). Emma and Jack stood there in silence, their hearts still racing from the unexpected encounter (独立主格结构). The forest seemed quieter now, as if holding its breath (方式状语从句). “Do you think it’ll be okay?” Emma asked, her voice full of concern (独立主格结构). Jack placed a comforting hand on her shoulder. “We did what we could,” he reassured her. “Sometimes, that’s all we can do (定语从句).” He glanced at the darkening sky, whispering, “It’s strong. It’ll survive.” (现在分词短语作状语) 学科网（北京）股份有限公司 $ Unit 6　At one with nature (限时:45分钟) ●Ⅰ 阅读理解 [2025·陕西渭南高三二模] 文体:说明文　主题:人与自然　词数:357 At first glance, a dead tree might just look like a lifeless, fallen log. But look closer: beneath the rotting bark (树皮), the wood is full of life. Upon its death, the tree’s tightly sealed tube system, previously used to transport nutrients and water, becomes empty and allows some creatures to pass through, according to Matteo Garbelotto, a professor at the University of California, Berkeley. These empty trunks, still standing upright, are also called snags or wildlife trees. Because of their verticality, they can host a high diversity of species that varies from top to bottom. Fallen trees, often called logs, are also valuable habitats, though for smaller species, Garbelotto says. Both types attract all sorts of life, starting with fungi (真菌). Fungi do much of the hard work of speeding up the decomposition process, softening the hard trunk into something with many small holes. This allows in a whole host of species seeking food and shelter: beetles get in to lay eggs, amphibians nestle under the bark, and birds feeding on insects build nests within the trunk itself. The collection of wildlife changes over the course of the tree’s decay (腐烂), with each new species contributing to and profiting from the process. Logs generally increase opportunities for insects, amphibians, and reptiles and make a good combination with snags, Garbelotto says. While some species like bark beetles and woodpeckers strongly prefer dead or rotting wood for nesting, others, including wood-decaying fungi, can only survive in deadwood. And it’s not just the animals that benefit from decaying trees. They provide natural protection and support for young seedlings to grow. As trees decompose, carbon and nitrogen stores are slowly reabsorbed into the soil, a critical step in nutrient recycling, both for young trees and for the larger ecosystem. From a climate perspective, letting trees rot is critical. Large trees in particular act as significant carbon sinks, which can absorb the carbon dioxide from burning fossil fuels, and allowing them to decompose naturally reduces the amount of carbon dioxide—and, thus, heat—in the atmosphere. Whenever possible, forestry experts prefer to leave dead trees untouched. (　)1.What is the main function of dead trees according to Paragraph 1? A.They block the growth of young seedlings. B.They provide food and shelter for large animals. C.They support species and maintain biodiversity. D.They have little ecological impact when decaying.

People tend to stay home during snowstorms, which means there are fewer people outside and not as many cars on the road. And birds tend to stay in their nests during severe weather, so they are quieter during a snowstorm too, according to the National Audubon Society. 2.　　　　 Snow absorbs sound, so when a fresh blanket of snow covers the landscape, it absorbs many of the sound waves, making it seem quieter outside, according to AccuWeather.  Sound absorption is rated on a scale of 0 to 1, AccuWeather reports. Something with a sound absorption rating of 0.5 absorbs 50 percent of sound, for example. The sound absorption rating of snow falls somewhere between 0.5 and 0.9. 3.　　　　　  The reason why snow is able to absorb sound is that it is porous (多孔的). Snowflakes are six-sided crystals, and they are filled with open spaces. Those spaces absorb sound waves, creating a quieting effect over a blanket of snow. However, not all snowfalls are equal when it comes to silencing the world outside. 4.　　　　 Usually a few inches of snow is needed to have a noticeable quieting effect, according to AccuWeather.  5.　　　　 The reason? The snowflakes change shape as they melt (融化), reducing the size of the spaces between the crystals. As temperatures fluctuate (波动) in winter, newly fallen snow can partially melt and then freeze. Once the snow turns into ice, it can actually increase nearby sounds because ice reflects sound waves rather than absorbing them.  A.As snow melts, it loses its silencing ability. B.It’s not your mind playing tricks on you. C.But there’s science behind the silence as well. D.That means it absorbs much of the surrounding sound.　 E.Just a dusting of snow isn’t enough to absorb much sound. F.It’s better to experience the quiet than just admire it indoors. G.So silence that falls over the world after a fresh snowfall is temporary. ●Ⅲ 语法填空 [2025·山东名校考试联盟高三二模] 文体:新闻报道　主题:人与自然　词数:204 The Guangdong-Hong Kong-Macao Greater Bay Area, surrounded by the Nanling Mountains and facing the South China Sea, is home to a diverse ecosystem.

Her curiosity and attention to detail made her an excellent observer. Jack, her childhood friend, was an experienced hiker. His practical skills and calm demeanor (举止) made him the perfect companion for such adventures. It was a sunny afternoon when they decided to explore the thick forest near their hometown. Armed with a map, a compass, and of course, a first-aid kit, they hiked deep into the woods. The singing of birds and the rustling of leaves filled the air, creating a harmonious atmosphere. However, as they walked further, the path became less clear, and the forest grew darker. The towering trees seemed to close in around them, and the sunlight barely filtered (透过) through the thick shade. Suddenly, they heard a weak sound, almost like a cry. Emma stopped in her tracks and turned to Jack. “Did you hear that?” she asked, her voice barely above a whisper. Jack nodded, his eyes scanning the thick underbrush. “It sounds like an animal in trouble,” he replied. Following the sound, they pushed through the bushes and found a small deer trapped in a bush, its leg caught in vines (藤蔓). The deer’s eyes were wide with fear, and it struggled helplessly, its tender body trembling with every movement. Emma knelt down slowly, her hands outstretched. “It’s okay, little one,” she whispered in a soft voice. “We’re here to help.” Jack pulled out his pocket knife and carefully began to cut the vines. “Hold its head gently,” he instructed Emma. “We don’t want it to panic.” Emma nodded, her hands steady as she held the deer’s head, whispering comforting words. The deer’s breathing was rapid, and its body trembled, but it seemed to sense that they were there to help. 注意:续写词数应为150个左右。 Paragraph 1: “Wait,” Emma said. “Its leg was injured.”          Paragraph 2: After a few tense minutes, Jack finally managed to free the deer’s leg.       A.词汇积累 1.log n.原木 2.seal vt.密封(容器);关闭;确定;封上(信封) 3.snag n.枯立木;突出物 4.decomposition n.分解,腐烂 5.seedling n.秧苗,幼苗 6.blanket n.厚层;毯子;毛毯 vt.以厚层覆盖 7.absorption n.吸收;专注 8.partially adv.部分地 B.靓句借鉴 However, not all snowfalls are equal when it comes to silencing the world outside. (阅读七选五, Para.6) 【赏析】 when it comes to…是一个固定搭配,在句中作状语,用于引出某个特定的话题或领域,意为“就……而言”“当谈到……时”。 【译文】 然而,就让外面的世界陷入寂静这一点而言,并非所有降雪都能达到同样的效果。 C.长难句分析 Large trees in particular act as significant carbon sinks, which can absorb the carbon dioxide from burning fossil fuels, and allowing them to decompose naturally reduces the amount of carbon dioxide—and, thus, heat—in the atmosphere. (阅读理解, Para.7) 【分析】 本句是由and连接的两个并列句;前一个分句中,which引导定语从句,修饰先行词carbon sinks;后一个分句中,allowing them to decompose naturally是动名词短语作主语。 【译文】 大树尤其可以作为重要的碳汇,吸收化石燃料燃烧产生的二氧化碳,而允许它们自然分解可以减少大气中的二氧化碳含量,从而减少热量。 学科网（北京）股份有限公司 $
