Moby Dick by Herman Melville This book is not to be missed by all who love sea stories.This is the most famous book about whaling that ever was.Melville got inspired to write this book when he was shipping aboard a Yankee(北方佬) whaler.The three-part climax is the most loved part of the book. Kon-Tiki by Thor Heyerdahl In this book,the mission of Heyerdahl is to prove that South American Indians have the option of migrating to Polynesia.He and his crew stand on a light raft and take one of the greatest real-life sea epics of all times. Treasure Island by Robert Louis Stevenson This is the grand work of all sea stories.Written in 1883,this adventure novel narrates a tale of “pirates and buried gold”.It is one of the most popular sea novels of all times and its influence on popular perception of pirates with eye patches and one-leg sailors with parrots on their shoulders is dominating the world literature and movies even today. Sailing Alone Around the World by Joshua Slocum Slocum is a Canadian who is probably the last of the great American sailor.His fame lies in the fact that he sailed his vessel,the Spray,in an unassisted sailboat.This book is definitely among the best of the real-life sea adventures. 1.What do the works by Heyerdahl and Slocum have in common? A.They have three-part climaxes. B.They focus on sailing and whaling. C.Their authors are Canadian sailors. D.They are based on the authors’ real experiences. 2.If a reader wants to read stories about pirates,which book can he or she choose? A.Moby Dick. B.Kon-Tiki. C.Treasure Island. D.Sailing Alone Around the World. 3.Where is this passage probably taken from? A.A book guide. B.An academic report. C.A conference notice. D.A fashion magazine. B (2025黑龙江双鸭山高二阶段练习) The ocean covers approximately 70% of Earth’s surface.It’s the largest livable space on our planet,and there’s more life there than anywhere else on Earth.Through exploration,we’re learning more about its biological,chemical,physical,and geological(地质的) aspects.Exploration leads to discovery,but before we can truly explore,we must map. Seafloor mapping provides a sense of what may lie beneath and guides decisions about where to explore.While the entire seafloor has been mapped using data collected from satellites,these data provide only a general picture of what’s there.Detail is limited on these maps,so some important geographical features like seamounts and objects like shipwrecks(失事船只) remain unseen. As of 2023,24.9% of the global seafloor had been mapped with modern high-resolution(高分辨率的) technology,usually fixed on ships,which can reveal the seafloor in greater detail.While almost 50% of the seafloor beneath U.S.waters had been mapped to these modern standards,the nation’s seafloor is larger than the land area of all 50 states.Thus,there’s still a significant amount of seafloor left to be mapped at high resolution. More is known about the seafloor than the species that call the ocean home.Seafloor maps can provide information about potential habitats,but they can’t identify species on the seafloor or provide information about how they interact with each other and their environments.Scientists estimate there may be between 700,000 and 1 million species in the ocean.Roughly two-thirds of these species have yet to be discovered or officially described,with almost 2,000 new species accepted by the scientific community each year. We have a great deal more to learn about our ocean and what lives in it,but progress is being made.We learn more and more each year.But the ocean will never be fully explored.Earth is constantly changing,and it’s important to understand these changes given the importance of the ocean in our everyday lives. 4.Why is seafloor mapping important for exploring the ocean? A.It reveals all objects on the seafloor. B.It shows the seafloor in greater detail. C.It guides decisions about where to sail. D.It provides a general picture of Earth. 5.Why is the seafloor beneath U.S.waters mentioned in paragraph 3? A.To stress the further task of mapping the seafloor. B.To explain the standards of mapping the seafloor. C.To illustrate the geographical features of the seafloor. D.To highlight the significance of mapping the seafloor. 6.What can we learn from the seafloor maps? A.The quality of the water. B.The environmental impact of sealife. C.The habitats of sea species. D.The endangered sea species. 7.What does the author intend to tell us in the passage? A.How can the seafloor be mapped? B.What species are living in the ocean? C.Why is it important to exploit the ocean? D.How much of the ocean has been explored? C (2025河北衡水武强中学高二期末) We live in a world of plastic.Shopping bags,drink bottles,your toothbrush and even your clothes are among the everyday items made from plastic.But plastic isn’t fantastic,and neither is the current state of our environment. Humans have been producing plastic on a large scale since 1950.We produce hundreds of millions of tonnes of plastic every year and production is only increasing.Unfortunately,most of it is used only once and then thrown away.Only a small part of plastic is recycled.The majority ends up in our oceans. A Plastic Ocean is a documentary film directed by the Australian journalist Craig Leeson.It dives into and investigates the terrible influence that plastic has caused to our environment,especially our ocean life.What starts off as an adventure to film the blue whale,the largest animal on the planet,leads to the shocking discovery of a thick layer of plastic floating in the middle of the Indian Ocean. The film sends the message that our actions and choices can severely impact the planet. Plastic is so widely used because it is durable and cheap.Unfortunately,this durability is the same quality that makes it so detrimental to the environment.Most plastics do not break down chemically.Instead,they break into smaller and smaller pieces that can persist in the environment for an extensive period of time. Because it is so affordable,developing countries use plastics extensively and much of the rubbish is washed into the ocean when it rains. When smaller pieces of plastic are eaten by animals in the sea,toxins(毒素) are released and become stored in their tissue.These toxins accumulate up the food chain and can eventually end up on our dinner tables.The consumption of the polluted seafood can cause many health problems including cancer,immune system problems,and even childhood developmental issues.Society’s huge appetite for plastic is literally poisoning us. 8.How long have we used plastic extensively? A.More than 40 years. B.More than 50 years. C.More than 60 years. D.More than 70 years. 9.Why did Craig Leeson direct A Plastic Ocean? A.To introduce the ocean life. B.To show the harm of plastic. C.To describe the beauty of the ocean. D.To indicate the common use of plastic. 10.What does the underlined word “detrimental” in paragraph 4 probably mean? A.Similar. B.Difficult. C.Harmful. D.Important. 11.Which proverb can best express the main idea of the last paragraph? A.You get what you pay for. B.There is no smoke without fire. C.Everything happens for a reason. D.What goes around comes around. Ⅵ.七选五 As long as we have been on Earth,we have used the sea around us.We take things from the sea,and we should give things to it. We take fish from the sea—millions of kilograms of fish,every year—to feed billions of people.　1　 We take minerals from the sea.One way to get salt is to place sea water in a shallow basin and leave it until it evaporates(蒸发).　2　 Much gold and silver dissolves(溶解) in the water of the sea,too.But the sea does not give them up by simple evaporation.Other gifts from the sea are pearls,sponges and seaweed.Pearls become jewelry.　3　 Seaweed becomes many kinds of foods—even candy and ice cream—as well as medicine.Believe it or not,fresh water is another gift from the sea.We cannot drink sea water.　4　 But sea water becomes fresh water when the salt and other impurities are removed.In the future,we will find ourselves depending more and more on fresh water from the sea.  The sea gives us food,fertilizer,minerals,water,and other gifts.What do we give to the sea?Garbage.　5　 Huge as it is,the sea cannot hold all the waste water that we pour into it.Dumping garbage into the sea is killing off sea life.Yet as the world population grows,we may need the sea and its gifts more than ever.  We are finally learning that if we destroy our sea,we might also destroy ourselves.Hopefully,it is not too late. A.Natural sponges become cleaning aids. B.We pollute the sea when we use it as a garbage dump. C.The area of the sea is becoming smaller and smaller. D.Along with salt,other minerals are left after evaporation. E.We even use their bones for fertilizer. F.Some of its ingredients may cause illness. G.We take a lot from the sea and give little to the sea.

real-life sea epics of all times.”以及“Sailing Alone Around the World by Joshua Slocum”部分中的“Slocum is a Canadian who is probably the last of the great American sailor.His fame lies in the fact that he sailed his vessel,the Spray,in an unassisted sailboat.”可知,两本书均基于作者真实的航海经历。故选D项。 2.C　细节理解题。根据“Treasure Island by Robert Louis Stevenson”部分中的“Written in 1883,this adventure novel narrates a tale of ‘pirates and buried gold’.”以及“its influence on popular perception of pirates with eye patches and one-leg sailors with parrots on their shoulders is dominating the world literature and movies even today”可知,该书以海盗为主题,如果一位读者想读关于海盗的故事,可以选择《金银岛》(Treasure Island)一书。故选C项。 3.A　推理判断题。通读全文,尤其是根据第一段中的“So,here we present our pick of the best four sea stories of all times in English literature.”可知,文章推荐了四部海洋题材的文学作品,并简要介绍了各书特色,符合书籍推荐指南的特征。故选A项。 【语篇导读】本文是一篇说明文。文章主要介绍了海洋测绘的情况,关于海洋和海洋中的生物,我们还有很多需要了解的,但我们正在取得进展。 4.B　细节理解题。根据第二段“Seafloor mapping provides a sense of what may lie beneath and guides decisions about where to explore.While the entire seafloor has been mapped using data collected from satellites,these data provide only a general picture of what’s there...”可知,海底测绘对于海洋探索很重要,卫星数据地图上有些细节看不到,海底测绘可以展示海底更详细的情况。故选B项。 5.A　推理判断题。根据第三段中的“While almost 50% of the seafloor beneath U.S.waters had been mapped to these modern standards,the nation’s seafloor is larger than the land area of all 50 states.Thus,there’s still a significant amount of seafloor left to be mapped at high resolution.”可知,第三段提到美国水域下方的海底是为了强调进一步绘制海底地图的任务还很艰巨。故选A项。 6.C　细节理解题。根据第四段中的“Seafloor maps can provide information about potential habitats,but they can’t identify species on the seafloor or provide information about how they interact with each other and their environments.”可知,通过海底地图我们可以了解海洋物种的栖息地。故选C项。 7.D　推理判断题。通读全文,并结合第四段中的“Scientists estimate there may be between 700,000 and 1 million species in the ocean.Roughly two-thirds of these species have yet to be discovered or officially described,with almost 2,000 new species accepted by the scientific community each year.”以及最后一段中的“We have a great deal more to learn about our ocean and what lives in it,but progress is being made.We learn more and more each year.But the ocean will never be fully explored.”可知,本文主要叙述了我们通过海底测绘技术进一步了解海洋,D项“海洋有多少部分已经被探索过了?”与文本叙述一致。故选D项。 【语篇导读】本文是一篇说明文。文章主要介绍了塑料的广泛使用及其对环境造成的严重影响,包括海洋污染、动物健康问题以及人类健康风险等,并通过介绍纪录片《塑料海洋》,强调了塑料污染问题的严重性。 8.D　细节理解题。根据第二段中的“Humans have been producing plastic on a large scale since 1950.”可知,人类自1950年以来就在大规模生产塑料。因此,我们广泛使用塑料已有70多年。故选D项。 9.B　推理判断题。根据第三段中的“A Plastic Ocean is a documentary film directed by the Australian journalist Craig Leeson.It dives into and investigates the terrible influence that plastic has caused to our environment,especially our ocean life.”可知,Craig Leeson执导《塑料海洋》这部纪录片是为了展示塑料对环境的危害。故选B项。 10.C　词句猜测题。根据画线词后的“Most plastics do not break down chemically.Instead,they break into smaller and smaller pieces that can persist in the environment for an extensive period of
