As the writer Robert Macfarlane has observed,humans are creatures of the air and light,and we have often regarded the spaces beneath our feet with prejudice,associating them with death,the unseen and unnameable. And while what Macfarlane calls the underland might be a place of ritual(宗教仪式) power as well as a place of burial,the ocean’s depths are more frequently linked with loss and forgetting. For European sailors across the waters of the Mediterranean sea and the Atlantic and Indian oceans,however,all that really mattered in navigational practices was knowing where potential obstacles and risks such as reefs and sandbars lay—a way of thinking that transformed the ocean’s depths into a blank irrelevance. It was not until the early 19th century that a more detailed scientific understanding of the deep began to take shape. In part,this was a result of the growing reach of the colonial powers:as the commercial and territorial desire of Europeans and Americans expanded to envelop the globe,the need for more accurate and more detailed knowledge of the ocean grew as well.But it also grew out of the experiences of whalers,whose voyages were now taking them far out into the open waters of the Atlantic and Pacific,and leading to an awareness of the great depths to which whales would often dive. But it was not until the Challenger expedition round the world on its pioneering scientific survey of the world’s oceans in the 1870s that the true extent of the deep ocean finally started to emerge.In the north-west Pacific,where the Mariana Trench plunges downwards into the planet’s crust(地壳),HMS Challenger recorded depths of more than 8,000 metres.Perhaps even more stunning to the scientists of the day,though,was Challenger’s discovery of tiny shells—and therefore living things—more than 7,000 metres down. 1.What is the common perception of the deep ocean? A.It is seen as a safe shelter for endangered species. B.It is often associated with death and the unknown. C.It is viewed as a place of ritual power and respect. D.It is regarded as a mysterious hiding place of treasures. 2.What did the European sailors viewed the deep ocean as? A.A place full of alien-like creatures. B.A navigational guide to avoid dangers. C.An important area to map and understand. D.An insignificant area unworthy of exploration. 3.What significant discovery did the Challenger expedition make? A.It recorded the first accurate depths of the ocean. B.It successfully sailed across all of the oceans in the world. C.It discovered living organisms at depths of the deep ocean. D.It found that no life could exist at depths greater than 7,000 metres. 4.What is the most suitable title for the passage? A.The Evolution of Deep Sea Exploration B.European Sailors and Ocean Navigation C.The Fear and Mystery of the Deep Ocean D.The Underland:A Place of Ritual and Burial B Shipping a Major Threat to the World’s Biggest Fish Marine biologists have noticed that whale shark numbers have been falling in recent years.But people just take it for granted.A new international study suggests that collisions (碰撞) with shipping traffic could be a major reason for the decrease. The study was led by the Marine Biological Association of the U.K.and the University of Southampton,along with experts in Australia and New Zealand.The study appeared in the publication Proceedings of the National Academy of Sciences. Researchers examined satellite data to observe about 350 whale sharks.They found that the world’s largest fish spend most of their time in waters used by large shipping boats. The study showed that information from the devices used to track their movements often ended in busy shipping paths.The researchers believe many sharks are probably being hit and killed by boats before sinking to the ocean floor. Mark Erdmann is with the University of Auckland in New Zealand and a scientist at the non-profit environmental organization Conservation International.He was one of the writers of the new study.Erdmann believes shipping is a major threat to whale shark populations. “...What the study found is that,indeed,there is a huge amount of overlap (重叠) between where whale sharks are moving and global shipping traffic.So,those are real collision-risk areas.Most deadly strikes between whale sharks and boats are likely to go unobserved or unreported.There are currently no laws to protect whale sharks against these kinds of collisions,” Erdmann said. Whale sharks can grow up to 20 meters long.They play an important part in providing healthy ocean environments. 5.What is the finding of the new study? A.Whale shark numbers have been falling. B.People take the decrease in the number of sharks for granted. C.Whaling ships mainly caused the decrease in the number of sharks. D.Sharks could mostly die from crashes into ships. 6.What contributed to the researchers’ finding? A.The place where sharks’ movements ended. B.Sharks’ unusual movements in the paths. C.Ships’ unusual travelling manners. D.The violent fight between sharks and ships. 7.What can we infer from Erdmann’s statement? A.Why sharks die is hard to find out. B.The number of ships should be reduced. C.Sharks are not important for reporters. D.The current laws are not strict enough. 8.What can we know from the last paragraph? A.Sharks are the biggest animals. B.The new finding is very important. C.Sharks will die out soon. D.It is hard to protect huge sharks. Ⅴ.七选五 (2025浙江宁波九校高二下期末) Patterns can be defined as predictable events or recurring responses to a specific situation.Our lives are often played out as a series of patterns.　1　  Bad habits are patterns of behaviour that are deeply wired into our lifestyles because of constant repetition.These habits may include more harmless ones such as eating loudly or dumping your shoes on the floor instead of putting them in the closet;the more moderate ones include procrastination(拖延) and gossiping;and the more insidious ones such as gaming,drugs,and alcoholic addiction.　2　 The adult brain can create new neurons(神经元) as well as trim and change existing neural pathways.Rewiring our brains to break patterns is possible.  　3　 Poverty comes with a host of problems and this elephant in the room cannot be ignored.There is no silver bullet to this complex problem,but thankfully,there are always rags-to-riches stories to show us it is possible and necessary to break the patterns of poverty.  Arguably,there are patterns that are beneficial to our lives such as an exercise or study routine.　4　 However,patterns create predictable results and when we choose to keep to outdated patterns,we limit ourselves to an expected outcome.　5　 If the study routine one has been following is not inspiring and does not help one to achieve his or her goals,isn’t it better to discard it?James Dyson,the inventor of the first bagless vacuum cleaner,made no fewer than 5,000 changes to his innovation before he got it right.If following a pattern of doing things leads us to failure and stagnation(停滞),it is better to disrupt the pattern than continue with it.  A.We need to put an end to them. B.We should certainly keep them. C.The cycle of poverty is a pattern that exists worldwide. D.It sometimes results in a sacrifice of growth and creativity. E.Breaking these patterns of behaviour is key to ending the habit. F.It is often not easy to break a pattern that has been rooted in a person or in a system. G.Most of us are stuck inside certain patterns,some of which are better broken than continued.

One hot summer day,the weather service issued a high-risk warning for rip currents,and Ben spent the day tense and watchful,scanning the water for any signs of trouble.He posted warnings at his lifeguard station and tried to educate visitors about the dangers,but most were more interested in enjoying their vacation than listening to safety advice. As the sun began to set,Ben prepared to end his shift.Just as he was packing up,a man named David Pew approached,his eleven-year-old son walking behind him.Pew was angry,demanding to know why the beach “closed” so early.Ben explained that swimming without lifeguards was unsafe,especially with the strong rip currents.“Rip currents?” Pew repeated and shook his head,dismissing Ben’s warnings as unnecessary rules.“The water looks fine to me,” he said,his tone clearly covering his determination to enjoy the beach with his son. Ben tried to remain calm,but Pew’s dismissive attitude frustrated him.“Enjoy the beach,” Ben said finally.As he walked to his car,he couldn’t shake the feeling that something might go wrong.Ben had just settled into his car when he saw Pew’s son running toward him,his face pale with fear.“My dad’s in trouble!” the boy cried.“The water’s carrying him out!” 注意: 1.续写词数应为150个左右; 2.请按如下格式在相应位置作答。

whether we should explore the ocean was held in our school library last Saturday. The competition started at 9:00 am and lasted two hours.Students who have a good command of English and show great interest in this topic took turns to give us a speech.Their performances on the stage were so wonderful that they were greeted with applause and praise. The activity was highly spoken of because not only did it enrich our school life but it also enabled us to realize the importance of protecting the ocean. Ⅷ.Upon hearing this,Ben’s heart raced.Grabbing a rescue tube,he dashed to the shoreline and found Pew was barely visible among the waves.Without hesitation,Ben plunged into the sea,pushed through the surging current and managed to grasp Pew.“Hold on!” Ben shouted,securing the rescue tube around Pew’s chest.Drawing on his previous training,Ben stayed calm,guiding Pew to the shore with steady strokes.Finally,Ben dragged Pew onto the sand as he collapsed,coughing and trembling.Pew’s son rushed over,tears streaming down his face.Pew’s voice shook as he whispered,“Thank you.I should have listened.”  The next morning,Pew and his son approached Ben,offering to join him in his efforts.“We owe you more than thanks,” Pew said.“We want to help.” True to his promise,Pew stood alongside Ben that day,sharing his story with beachgoers.His experience struck a chord,and visitors listened intently.Meanwhile,Pew’s son eagerly handed out safety leaflets,urging others to be cautious.For the first time,Ben saw genuine awareness in visitors’ eyes.As the days passed,the beach,once filled with dismissive glances,now echoed with concern and respect.Through one act of courage,Ben not only saved a life but also ignited a ripple of change.  知识积累卡 一、1.根;根茎;根部;根源　生根的;根深蒂固的　2.先驱;开拓者　开创　首创的;先驱的;开创性的　3.白手起家的 4.丢弃,抛弃　被抛弃的人/物　5.扰乱,使中断 二、1.范围;影响力　可到达的距离　到达;伸手触(或拿) 2.使付出;使丧失　价钱为;花费　价钱;费用;代价;牺牲 三、1.成形　2.在某种程度上;部分地　3.以……方式发展 4.许多的;一大群　5.良方,高招　6.弄清楚……　7.漠视……;认为…… 四、1.并列复合句　定语从句　伴随状语 正如作家罗伯特·麦克法兰所观察到的,人类是空气和光的生物,我们经常带着偏见看待脚下的空间,将它们与死亡、看不见的和无法命名的东西联系在一起。 2.状语　宾语从句　定语从句　同位语　定语从句 然而,对于在地中海、大西洋和印度洋航行的欧洲水手来说,在航海实践中真正重要的是知道潜在的障碍和风险,如暗礁和沙洲在哪里——这种思维方式将海洋深处变成了空白的无关紧要的东西。 3.简单句　伴随状语 此次任务使用了雪龙号、雪龙2号两艘科考破冰船和一艘补给船,搭载了来自国内80多个单位的460余名科研人员,总航程超过15万千米。 学科网（北京）股份有限公司 $
