Inside the temple, a twelve-meter-tall statue of Athena was sculpted out of wood and covered in gold and ivory. The Parthenon 　5　(use) as a Christian church in the sixth century, and later changed into a mosque(清真寺) in the fifteenth century. This lasted until 1687, 　6　 a war broke out and left the building in ruins.  Between 1800 and 1803, Thomas Bruce,　7　 art collector and British diplomat, removed some of the Parthenon􀆳s sculptures and sent them to London, where they can still be seen today in the British Museum. The rest remain in the Acropolis Museum, which hopes to reclaim the 　8　(lose) sculptures and complete the story.  　9　 its partial destruction, the Parthenon remains a source of inspiration for architects and artists worldwide. As an architectural miracle that 　10　(stand) the test of time for centuries, the Parthenon will doubtless continue to arouse wonder and admiration for many years to come.  1.　　　　　　　2.　　　　　　　3.　　　　　　　4.　　　　　　　5.　　　　　　   6.　　　　　　　7.　　　　　　　8.　　　　　　　9.　　　　　　　10.　　　　　　   Ⅲ.阅读理解 (2025江苏苏州月考) People often vaguely refer to “the middle of nowhere”, but as it turns out, scientists have actually figured out precisely where that point is. Point Nemo, the most remote location on Earth, is officially known as the “Oceanic Pole of Inaccessibility”, or the point in the ocean farthest from land. There are no human inhabitants anywhere near Point Nemo. And scientists chose to call the location “Nemo” because it is Latin for “no one” and as a reference to Jules Verne􀆳s submarine captain from 20,000 Leagues Under the Sea. The location is so isolated that the closest people to Point Nemo are not even on Earth. Astronauts aboard the International Space Station are around 258 miles from the Earth􀆳s surface at any given time.Since the inhabited area closest to Point Nemo is more than 1,000 miles away, the humans in space are far closer to the pole of inaccessibility than those on land. Not even the man who first calculated the precise location of Point Nemo has ever visited it. In 1992, Croatian survey engineer Hrvoje Lukatelaset set out to find the exact point in the Pacific that was farthest away from any land using a computer program. It is very possible that no human has ever passed through Point Nemo􀆳s exact coordinates. As for non-human inhabitants, there aren􀆳t very many of those around Point Nemo either. Point Nemo􀆳s coordinates fall within the South Pacific Gyre, an enormous rotating current that prevents nutrient-rich water from flowing into the area. Without any food sources, sustaining most life in this part of the ocean is impossible. Point Nemo does, however, have at least one other eerie claim to its name. Due to its remoteness and distance from shipping routes, the area around Point Nemo was chosen as a “spaceship graveyard”. According to CNN, NASA first started using the region in 1971. Since then, more than 263 pieces of space junk have crashed into the area, including some of the world􀆳s greatest spacecraft, the Russian space station Mir and NASA􀆳s first space station, Skylab. 1.Why is Point Nemo referred to as the “Oceanic Pole of Inaccessibility”? A.It is the farthest point from any land. B.It is the deepest point in the ocean. C.It is located at the center of the Pacific Ocean. D.It is a place that only astronomers have ever visited. 2.What can be learned about the isolation of Point Nemo? A.There are several small islands nearby. B.It is frequently visited by marine biologists. C.It is within reach of commercial shipping routes. D.The nearest humans to Point Nemo are often astronauts. 3.What do we know about the environmental conditions around Point Nemo? A.The area is rich in marine biodiversity due to its isolation. B.The strong currents of the South Pacific Gyre support a thriving ecosystem. C.The region is frequently visited by marine researchers for its unique ecosystem. D.The lack of nutrients makes it difficult for most marine life to survive in the area. 4.What is the crucial aspect when choosing an area as a “spaceship graveyard”? A.Proximity to major coastal cities. B.Depth of the ocean at the chosen location. C.Distance from any land mass and human activity. D.Presence of strong ocean currents that could disperse debris. Ⅳ.七选五 (2024河南名校联考) Fungi(真菌) play an important role in ecosystems, are a source of food, and make a key contribution to the world of medicine. 　1　  An estimated two million fungal species—more than 90% of all fungi—have yet to be described by science, according to a science reporter. 　2　 Scientists are trying to find out more about this largely unexplored world, but it is challenging. Dr Martyn Ainsworth, a senior researcher from Royal Botanic Gardens, Kew, in London, says, “We can grow a certain number in the lab. 　3　 This has held back a lot of research.”  　4　 “A lot of people are afraid of poisonous mushrooms,” says Dr Jassy Drakulic, a plant pathologist, “but only a very small proportion of the thousands of species of fungi in the world can cause disease.” Most are harmless and often beneficial, called by some “the hidden helpers of our environment”.   Furthermore, some fungi provide food and shelter for wildlife, help plants absorb water and nutrients and recycle waste and dead substances. Other types of fungi grow on the roots of trees and other plants, forming a huge underground network that helps nourish these plants. 　5　  So, next time you add mushrooms to your dinner, take a painkiller for a headache, or go for a walk through the woods, remember to thank the living things that made it all possible—fungi. A.Are mushrooms a type of fungus? B.So, why do we know so little about them? C.But there is a whole host of fungi that we cannot grow in the lab. D.Wetlands are important because they provide food and shelter for wildlife. E.The fact that we know so little about fungi leads us to misunderstand them. F.“Fungi are really the behind-the-scenes team doing all the work,” adds Dr Ainsworth. G.In the UK, there are around 25,000 species of fungi—five or six times more than plants. 1.　　　 2.　　　 3.　　　 4.　　　 5.　　　   Ⅴ.读后续写 (2025陕西咸阳月考) 阅读下面材料,根据其内容和所给段落开头语续写两段,使之构成一篇完整的短文。 It was a brilliant summer day. Alex, a 16-year-old boy crazy about adventures, managed to talk his friend, Max, into joining him for a hike in the nearby mountains. They carefully filled their backpacks with water, snacks, and a map, excited about the day􀆳s adventure. As they walked along the winding trail, the view was amazing. Green trees surrounded them on all sides, and the cheerful singing of birds filled the air. They talked and laughed, fully enjoying the beauty of nature. However, as they got deeper into the mountains, the trail became less clear. Alex took out the map and studied it, only to find that they had somehow left the marked path. Max started to look anxious. “Alex, I􀆳m really worried we can􀆳t find our way back. This doesn􀆳t seem right,” he said. Alex tried to stay calm. “Don􀆳t worry, Max. We just need to go back a little and find the main trail again.” But when they turned around, they realized it was hard to remember exactly which way they had come. Suddenly, they heard a loud growl from nearby. Their hearts jumped. Alex whispered, “Don􀆳t move, Max. It might be a wild animal.” They stood there, scared stiff, not knowing what was going to come out of the bushes. 注意:续写词数应为150个左右。 Slowly, a large bear emerged from the bushes.              　　After what felt like an eternity, the bear finally lost interest and wandered away.                答案与分层梯度式解析 Part 3　Developing ideas & Presenting ideas 基础过关练 Ⅰ.1.substances　2.Furthermore　3.millimetres 4.astronomy Ⅱ.1.动词;缩水　句意:这种布料洗涤时很容易缩水。 2.动词;退缩,畏缩　句意:这个小男孩很害怕,躲着这个高个子男人。 3.动词;去除,摒除　句意:你应该摒除你脑子里这类荒唐的想法。 4.动词;解雇,开除　句意:这位女士在恢复期间被公司解雇了,她很难过。 Ⅲ.1.to　考查介词。句意:呼吸这种被污染的空气相当于一天抽十根烟。be equivalent to意为“等于……,相当于……”。故填to。 2.notable　考查形容词。句意: 不过,我在新媒体领域有个明显的短板——我很少出现在镜头前,因为我长了一张只适合广播的脸。设空处修饰名词gap,应用形容词;由语境可知,设空处表示“显著的”,故填notable。 3.corresponding　考查形容词。句意:我想撰写关于 24 种蝴蝶的栖息地及与其对应的生态保护的故事。由空后的“ecological protection stories”并结合语境可知,空处修饰名词stories,要用形容词作定语,表示“相应的,对应的”,故填corresponding。 4.to draw/drawing　考查非谓语动词。句意: 辛巴的故事年复一年地吸引着观众,这是有原因的:它是一部令人惊叹的作品,有着令人惊叹的布景和感人的配乐。continue to do/doing sth.表示“继续做某事”。 5.applying; applicant; application　考查非谓语动词和名词。句意:申请职位时,每位申请者都必须在面试前填写申请表。“When　　　for a position”为句子的状语,其逻辑主语为“every　　　”,由第一空前的When可知,此处为状语从句的省略,补充完整后为“When every　　　is applying for a position”,此处省略了“every　　　is”,故第一空填applying。由第二空前的every及句意可知,第二空应用名词单数作主语,表示“申请者”,故填applicant。由语境可知,此处表示“申请表”,application form意为“申请表”,故第三空填application。  6.has been investigated; investigator; investigation　考查时态、语态、主谓一致和名词。句意:这次事故已经调查一周了,调查员说事故的起因还在调查中。第一空为and前的分句的谓语,由第一空后的时间状语for a week和and后分句的谓语动词says可知要用现在完成时;主语The accident是第三人称单数,与investigate之间是被动关系,应用现在完成时的被动语态,故第一空填has been investigated。由第二空前的the和语境可知,第二空应用名词,表示“调查员”,且由says可知应用单数形式,故第二空填investigator。由语境可知,第三空使用的是固定搭配under investigation,表示“在调查中”,故第三空填investigation。 Ⅳ.1.offer a window into 2.Burying her head in 3.leaving his father sitting 4.Not every athlete can perform 5.①Whoever fails in the competition ②who fails in the competition 能力提升练 Ⅰ.1.the　考查冠词。across the globe表示“世界各地”。故填the。 2.to explore　考查动词不定式。分析句子可知,设空处修饰名词attempts,应用动词不定式作后置定语。故填to explore。 3.earliest　考查形容词的最高级。根据“Among”所表达的语境和空前的the可知,此处表示“最早的沉船”,因此用形容词的最高级。故填earliest。 4.discoveries　考查名词复数。根据空前形容词biological和空后的are可知,此处应用名词复数。故填discoveries。 5.valuable　考查形容词。设空处修饰空后的名词source,应用形容词;结合语境可知,设空处表示“有价值的”,故填valuable。 6.which　考查定语从句。分析句子可知,“some of 　6　 are completely new to us”为“代词+介词+关系代词”结构引导的非限制性定语从句,修饰先行词natural resources,关系词在从句中作介词of的宾语,指物,故应用which引导从句。  7.formed/was formed　考查时态、语态和主谓一致。海底形成是过去的事,应用一般过去时。form在此处表示“(自然事物)形成”,既可作及物动词也可作不及物动词。form作不及物动词时没有被动语态,故可以填formed; form作及物动词时,此处主语the sea bed与form之间是被动关系,应用被动语态,且主语是单数,故也可以填was formed。 8.Being　考查现在分词。句中已有谓语have been,设空处应用非谓语动词作状语;句子主语the ocean depths与be之间为逻辑上的主动关系,因此用现在分词。设空处位于句首,所填词的首字母需大写。故填Being。 9.beyond　考查介词。由语境可知,此处表示“超出”,应用介词beyond,beyond the reach of表示“超出……可及的范围”。故填Beyond。 10.cooperation　考查名词。设空处作介词through的宾语,应用名词;由语境可知,此处表示“合作”,故填cooperation。 Ⅱ.◎语篇解读　本文是一篇说明文。文章主要介绍了希腊雅典卫城的帕台农神庙。 【高频词汇】　1.accomplishment n.成就　2.bring forth使产生;使出现;生产　3.reclaim v.要求归还;利用;改造　4.arouse v.激起;引起 1.proof　考查名词。句意:它建于公元前5世纪,是古希腊文化和艺术成就的证明。介词as后应用名词作宾语,prove的名词形式为proof,此处表抽象概念,proof用作不可数名词,故填proof。 2.Particularly　考查副词。句意:特别是它和谐的比例和对细节的仔细关注彰显了希腊人对完美的执着追求。设空处作状语,修饰整个句子,应用副词;由语境可知设空处表示“尤其,特别”,位于句首,首字母需大写,故填Particularly。 3.its　考查形容词性物主代词。设空处修饰名词outside,应用形容词性物主代词,故填its。 4.demonstrating　考查现在分词。句意:这些图像使希腊历史和神话中的场景出现,展示了希腊人通过艺术讲述故事的卓越能力。本句已有谓语brought forth,设空处应用非谓语动词。主语These images与demonstrate之间是主动关系,应用现在分词作状语,故填demonstrating。 5.was used　考查时态、语态和主谓一致。句意:帕台农神庙在六世纪被用作基督教教堂,后来在十五世纪变成了清真寺。设空处为句子谓语;此处描述过去的事情,且主语The Parthenon和use之间是被动关系,应用一般过去时的被动语态;主语为第三人称单数,be动词用was,故填was used。 6.when　考查定语从句。句意:这种情况一直持续到1687年,当时战争爆发,使这座建筑成了一片废墟。设空处引导定语从句,先行词是1687,关系词在从句中作时间状语,所以用关系副词when引导定语从句。故填when。 7.an　考查冠词。此处表泛指,指“一位艺术品收藏家兼英国外交官”,应用不定冠词,且art的发音以元音音素开头,故填an。 8.lost　考查形容词。句意:其余的留在卫城博物馆,该博物馆希望取回丢失的雕塑并完成这个故事。设空处修饰名词sculptures,作定语,应用形容词,表示“丢失的”,故填lost。 9.Despite　考查介词。句意:尽管帕台农神庙遭到了部分破坏,但它仍然是全世界建筑师和艺术家的灵感来源。设空处后接名词短语,表示“尽管”,应用介词despite,句首单词首字母需大写,故填Despite。 易错归因 　　此题易误填Though或Although,这两个词虽然也表示“尽管;虽然”,但它们是连词,引导让步状语从句,而此处后接名词短语,应用介词。 10.has stood　考查时态和主谓一致。句意:作为几个世纪以来经受住时间考验的建筑奇迹,帕台农神庙无疑将在未来的许多年里继续引起惊叹和钦佩。设空处为that引导的定语从句的谓语,根据从句的时间状语“for centuries”可知,从句要用现在完成时;从句主语that指代先行词an architectural miracle,表示单数意义,故填has stood。 Ⅲ.◎语篇解读　这是一篇说明文。文章介绍了地球上最偏远的地点尼莫点,它远离陆地、生物稀少,还被称为“航天器墓园”。 【高频词汇】　1.precisely adv.精确地;准确地 2.literally adv.确实;真正地;根据字面意思　3.isolated adj.偏远的;孤零零的;孤独的　4.sustain v.维持……的生命;支持;承受住 【熟词生义】　1.coordinate熟义:v.协调;搭配　生义:n.坐标　2.current 熟义:adj.现在的;通用的　生义:n.水流 【差距词汇】　1.vaguely adv.略微;不详细地;茫然地;不确切地　2.eerie adj.怪异的 1.A　细节理解题。根据第一段中的“Point Nemo...is officially known as the ‘Oceanic Pole of Inaccessibility’, or the point in the ocean farthest from land.”可知,尼莫点被称为“海洋难抵极”是因为它是离任何陆地最远的地方。故选A。 2.D　细节理解题。根据第二段最后一句“Since...the humans in space are far closer to the pole of inaccessibility than those on land.”可知,离尼莫点最近的人类通常是宇航员。故选D。 3.D　细节理解题。根据第三段中的“Point Nemo􀆳s coordinates...prevents nutrient-rich water from flowing into the area. Without any food sources, sustaining most life in this part of the ocean is impossible.”可知,尼莫点的坐标位于南太平洋环流内,这是一股巨大的旋转洋流,阻止了富含营养的水流进入该区域,这片海洋区域没有任何食物来源,很难维持大多数生物的生存。故选D。 4.C　推理判断题。根据最后一段第二句“Due to its remoteness and distance from shipping routes, the area around Point Nemo was chosen as a ‘spaceship graveyard’.”可知,尼莫点被选为“航天器墓园”是因为它偏远且远离航线。由此推知,选择一个区域作为“航天器墓园”的关键因素是与任何陆块和人类活动之间的距离。故选C。 Ⅳ.◎语篇解读　本文是一篇说明文,主要介绍了真菌的作用。 【高频词汇】　1.estimated adj.估计的;预计的　2.find out查明;弄清　3.hold back阻挡;妨碍进展 4.misunderstand v.误解;误会 【熟词生义】　host 熟义:n.主人;主持人　生义:n.许多;大量 【差距词汇】　proportion n.比例;份额 1.B　过渡句。上文“Fungi play an important role in ecosystems, are a source of food, and make a key contribution to the world of medicine.”提到真菌有重要作用,下文“An estimated two million fungal species—more than 90% of all fungi—have yet to be described by science”说90%以上的真菌尚未被科学描述;结合选项可知B项“So, why do we know so little about them?”承上启下,B项中的“them”指代上文中的“Fungi”。故选B。 2.G　细节句。根据上文“An estimated two million fungal species—more than 90% of all fungi—have yet to be described by science”可知,估计有两百万种真菌尚未被科学描述;G项“In the UK, there are around 25,000 species of fungi—five or six times more than plants.”承接上文,进一步描述真菌的庞大数量。故选G。 3.C　过渡句。上文“We can grow a certain number in the lab.”提到可以在实验室里培育一定数量的真菌,下文“This has held back a lot of research.”说这阻碍了很多研究的进展;结合选项可知C项“But there is a whole host of fungi that we cannot grow in the lab.”与上文构成转折关系,与下文构成因果关系,承上启下。故选C。 4.E　主旨句。设空处位于段首,推断是本段主旨句。根据下文“A lot of people are afraid of poisonous mushrooms”和“but only a very small proportion of the thousands of species of fungi in the world can cause disease”可知,真菌被人们误解,E项“The fact that we know so little about fungi leads us to misunderstand them.”能概括本段主旨,符合语境。故选E。 5.F　细节句。根据上文“Other types of fungi grow on the roots of trees and other plants, forming a huge underground network that helps nourish these plants.”可知,真菌生长在树木和其他植物的根部,形成一个巨大的地下网络,帮助滋养这些植物;F项“‘Fungi are really the behind-the-scenes team doing all the work,’ adds Dr Ainsworth.”总结上文真菌的作用,F项中的“behind-the-scenes”呼应上文中的“a huge underground network”。故选F。 Ⅴ. 写作指导 情节线 情感线 时间 a brilliant summer day 兴奋 放松,开心 焦虑、担心 恐惧、茫然 他们有何感受? (惊恐、放松 还是镇静) 他们的心情有 什么变化? 地点 in the nearby mountains 人物 Alex, Max 开端 喜欢探险的Alex和好朋友Max带好装备一起去附近的山上远足。 发展 山上风景优美,他们有说有笑,充分享受大自然的美丽。但他们进入深山区后,路不清晰了,他们偏离了标记路径,也找不到回去的路。 高潮 他们突然听到附近有咆哮声,意识到可能遇到了野生动物,他们站在原地,心里很害怕,不知道会面对什么。 Para. 1 慢慢地,一头大熊从灌木丛中钻了出来。(第一段首句) ①熊见到他们有什么反应? ②Alex和Max的应对措施是什么? ③熊对他们两个做了什么? ④他们两个的反应是什么? Para. 2 过了好久,熊终于失去了兴趣,走开了。(第二段首句) ①他们两个有什么反应? ②他们之后做了什么? ③他们回到主路并走出大山了吗? ④他们学到了什么? One possible version: Slowly, a large bear emerged from the bushes. Its eyes were fixed on them, and it let out another threatening growl. Alex knew they couldn􀆳t run. Remembering what he􀆳d read about bear encounters, he told Max in a low voice, “Don􀆳t make any sudden moves. Just stand tall and make yourself look big.” They opened their jackets wide, spread their arms and stood as tall as possible. The bear took a few steps closer, sniffing the air. Heart pounding, Alex tried to stay calm. He hoped their actions would prevent the bear from attacking. After what felt like an eternity, the bear finally lost interest and wandered away. Alex and Max let out a huge sigh of relief. Their legs were shaking, but they knew they had to get out of there quickly. Alex grabbed the map again and this time, with more caution, they managed to find the main trail. They followed it closely and didn􀆳t stop until they were safely out of the mountains. That day, they learned the importance of being prepared and following the right path during an adventure. 1 学科网（北京）股份有限公司 $
