He joined a huge fleet of ships, and his journey helped to extend the ancient maritime trade routes across the wide blue sea. Every captain had to negotiate with the local rulers before entering a new channel, and the merchants always kept a careful record in hand. My grandfather always listened to this story with wonder and great respect, because the sea had always been a strong bond between different peoples and cultures all around the world. Such journeys were full of danger, but they also brought new ideas to every port they visited. The great sea route was truly in a league of its own in those days. When our hero behold the tall towers of the foreign city, he knew that his long voyage had reached its end, and he was warmly welcomed like a member of a higher league. The local king and his wise ministers were deeply interested in politics and trade, and he treated the merchants with mercy and respect at every meeting. He even asked the merchant about his profession and offered him a place in a grand tournament of ships. The merchant's ship was a fine mixture mixture of old and new styles, and its honest crew always kept their word, so they never had to withdraw from any agreement they had once made with their friends. In modern times, the sea still connects our world in many ways. Today a captain can sit in his cabin with a laptop, read the latest news coverage coverage of the ocean, and watch a press conference press conference online while his ship moves on. Sailors applaud the scientists who study marine life, and governments may tax the goods that cross the sea. Some teams use a manned submersible to explore the underwater world, where colourful coral forests grow and millions of colourful fish begin their long migration every year. Meanwhile, modern ships can carry thousands of gallons of fuel, and a large ship's log records every mile of the long journey across the sea. However, the sea can sometimes also be dangerous and unfair to innocent people. Some people exploit the ocean and take more than they truly need, while others may commit murder or steal the possessions of honest sailors. An opponent of justice may try to arrest innocent fishermen on false charges, and a cruel captain might treat his own crew like prisoners. But in the end, those who respect the sea will always have mercy on their side, because the ocean rewards honest people with its endless treasures, and every record in the directory of the world's seas tells the same true story of courage, hope and friendship for the future. B. 语境串记单词（汉语译文） 很久以前，我的曾祖父给我讲了一个故事(tale)：一位勇敢的商人(merchant)决定从皇城(royal)的港口起航(set sail)，把丝绸和香料(spice)运往遥远的国度。他加入了一支庞大的船队(fleet)，他的航行帮助扩展(extend)了古老的海洋(maritime)跨海贸易路线。每一位船长在进入新的航道(channel)前都必须与当地统治者谈判(negotiate)，商人们也总是把手头(in hand)的记录仔细保存。祖父满怀惊奇与敬意地听完这个故事，因为大海一直是全世界不同民族和文化之间牢固的纽带(bond)。 这条伟大的海路在当时真是独领风骚(in a league of one's own)。当我们的英雄看见(behold)异国城市的高塔时，他知道漫长的航行终于到了尽头，他受到欢迎，仿佛属于更高等级(league)的一员。当地国王对政治(politics)和贸易深感兴趣，每次会面都以仁慈和尊敬对待商人，还询问商人的职业(profession)，并邀请他参加一场盛大的船只锦标赛(tournament)。商人的船是新旧风格的巧妙混合(mixture)，诚实的船员从不食言，因此他们从不曾从(withdraw from)任何与朋友达成的协议中退出(withdraw)。 在当今时代，海洋仍然以多种方式连接着我们的世界。如今，船长可以坐在舱内，用笔记本电脑(laptop)阅读关于海洋的新闻报道(coverage)，在线观看记者招待会(press conference)，而他的船继续前行。水手们为研究海洋(marine)生物的科学家鼓掌(applaud)，政府也会对跨海的货物征税(tax)。一些团队使用载人(manned)潜水器(submersible)探索水下(underwater)世界，那里生长着色彩斑斓的珊瑚(coral)森林，每年都有数百万条鱼开始它们的迁徙(migration)。与此同时(meanwhile)，现代船只可以携带数千加仑(gallon)的燃料，船的航行日志(log)记录着漫长航程的每一英里。 然而，海洋对人们来说也可能危险而不公。有些人开发(exploit)海洋，索取超过真正所需，而另一些人可能犯下谋杀(murder)罪，或偷窃诚实水手的财物(possession)。不义的对手(opponent)可能以虚假的罪名逮捕(arrest)无辜的渔民，残暴的船长可能像对待囚犯一样对待自己的船员。但最终，尊重海洋的人总会得到仁慈(mercy)的眷顾，因为海洋用无尽的财富回报诚实的人，而世界海洋名录(directory)中的每一笔记录都讲述着同样关于勇气与希望的真实故事。 第二部分：词形转变表 序号 原词 词形变化 1 tale n.故事 teller (n.) 讲述者；tell (v.) 讲述；tales (复数)；storyteller (n.) 讲故事的人 2 extend vt.扩展 extension (n.) 扩展；extended (adj.) 延长的；extensive (adj.) 广泛的 3 negotiate vt.谈判 negotiation (n.) 谈判；negotiator (n.) 谈判者；negotiated (过去式)；negotiating (现在分词) 4 behold vt.看 beheld (过去式)；beholder (n.) 观看者；beholding (现在分词) 5 royal adj.皇家的 royalty (n.) 皇室；royally (adv.) 像王室一样 6 withdraw vi.撤回 withdrawal (n.) 撤回；withdrew (过去式)；withdrawn (过去分词)；withdrawing (现在分词) 7 maritime adj.海的 mariner (n.) 海员；marine (adj.) 海洋的；seafaring (n.) 航海 8 politics n.政治 political (adj.) 政治的；politician (n.) 政治家；politically (adv.) 政治上 9 profession n.职业 professional (adj.) 专业的；professionally (adv.) 专业地；professor (n.) 教授 10 applaud vt.鼓掌 applause (n.) 掌声；applauded (过去式)；applauding (现在分词) 11 migration n.迁徙 migrate (v.) 迁徙；migratory (adj.) 迁徙的；migrating (现在分词) 12 exploit vt.开发 exploitation (n.) 开发；exploited (过去式)；exploitable (adj.) 可开发的 13 murder vt.谋杀 murderer (n.) 谋杀犯；murderous (adj.) 凶残的；murdered (过去式) 14 mercy n.仁慈 merciful (adj.) 仁慈的；merciless (adj.) 残忍的；mercifully (adv.) 仁慈地 15 arrest vt.逮捕 arrested (过去式)；arresting (现在分词)；arrest warrant 逮捕令 第三部分：梯度复现与多题型练习 题型1：英汉互译（30题） 乐思英语 ·语境串记单词 第 2 / 16 页 学科网（北京）股份有限公司 子题A：英译中（20个） 1. tale → __________ 2. merchant → __________ 3. extend → __________ 4. negotiate → __________ 5. fleet → __________ 6. royal → __________ 7. spice → __________ 8. withdraw → __________ 9. channel → __________ 10. maritime → __________ 11. bond → __________ 12. politics → __________ 13. profession → __________ 14. tournament → __________ 15. mixture → __________ 16. coverage → __________ 17. applaud → __________ 18. migration → __________ 19. exploit → __________ 20. mercy → __________ 子题B：中译英（10个） 1. 起航 → __________ 2. 看见 → __________ 3. 等级 → __________ 4. 在手头的 → __________ 5. 笔记本电脑 → __________ 6. 记者招待会 → __________ 7. 征税 → __________ 8. 载人的 → __________ 9. 潜水器 → __________ 10. 水下的 → __________ 【答案与解析】 子题A（英译中）： 1. tale — 故事 2. merchant — 商人 3. extend — 扩展 4. negotiate — 谈判 5. fleet — 舰队 6. royal — 皇家的 7. spice — 香料 8. withdraw — 撤回 9. channel — 航道 10. maritime — 海的 11. bond — 纽带 12. politics — 政治 13. profession — 职业 14. tournament — 锦标赛 15. mixture — 混合 16. coverage — 报道 17. applaud — 鼓掌 18. migration — 迁徙 19. exploit — 开发 20. mercy — 仁慈 子题B（中译英）： 1. set sail 2. behold 3. league 4. in hand 5. laptop 6. press conference 7. tax 8. manned 9. submersible 10. underwater 题型2：词形变换（15题） 1.

An old sailor told us a tale about the brave merchants of the past, who sailed across the sea to trade with foreign lands. Our teacher, an expert on marine life, told us that the sea covers most of our planet and that it connects every country in the world. She explained that the early sailors used simple tools to set sail and explore new lands, and that they had to negotiate with foreign rulers before they could trade with them. In the afternoon, we visited a science centre near the port, where we saw a real submersible used by scientists to explore the underwater world. The machine can carry two people and go down to a great depth, where the sunlight never reaches. We watched a film about the colourful coral reefs, which are home to millions of fish, and we learned how the fish begin their migration every year to find food and warm water. The centre also showed us the log book of an old ship, which recorded every mile of its long journey across the sea, and we learned that the ship had once been part of a large fleet that carried goods to many countries. The teacher also talked about the dangers that the ocean faces today. Some people exploit the sea too much and catch more fish than they need, which harms the balance of nature. She told us that the government has passed new laws to tax the large fishing boats and to protect the young fish during the breeding season. A famous scientist held a press conference to call on everyone to protect the ocean, and the audience applauded loudly after her speech. Meanwhile , the coast guards began to patrol the sea more often, and the big ships had to record every gallon of fuel they used. On our way home, we saw the coast guards arrest a man who had stolen the possessions of the fishermen at the port. Our teacher reminded us that the sea is not only a source of wealth but also a place that needs our protection and mercy. She said that every student can play a part, and that we should never treat the ocean like an opponent to be conquered, nor withdraw from our duty to protect it. Instead, we should work together to keep the sea clean and safe for all living things, because the ocean is the common home of every creature on the earth. 1. What did the students see at the science centre near the port? A. A real fishing boat. B. A large oil ship. C. A real submersible and an old ship's log book. D. A map of the world. 2. What does the underlined word "submersible" in Paragraph 2 most probably mean? A. A machine that can travel under water. B. A kind of sea bird. C. A tall building near the sea. D. A type of fishing net. 3. What can we infer from the passage? A. The students were afraid of the sea. B. The ocean faces no danger at all. C. Only adults can protect the ocean. D. We should protect the ocean and use its resources wisely. 4. What is the main idea of the passage? A. How to catch fish in the sea. B. Why the sea is dangerous. C. A science class that taught students about the ocean and the need to protect it. D. How to build a submersible. 【答案与解析】 1. 答案：C 解析：细节理解题。答案 C。原文第2段写道："we saw a real submersible used by scientists"、"The centre also showed us the log book of an old ship"，与 C 项一致。 2. 答案：A 解析：词义猜测题。答案 A。原文第2段写道："a real submersible used by scientists to explore the underwater world"，可推断 submersible 意为"潜水器"，与 A 项一致。 3. 答案：D 解析：推断题。答案 D。原文第3-4段写道："we should never treat the ocean like an opponent to be conquered"、要"keep the sea clean and safe"，可推断应合理利用并保护海洋，对应 D 项。 4. 答案：C 解析：主旨大意题。答案 C。全文讲述学生们在海边科学课上认识海洋、观看潜水器与航海日志，并懂得保护海洋的重要，对应 C 项。 第四部分：关联拓展与循环巩固 A. 词汇网络图（话题：Reaching Out Across the Sea） 类别 词汇 同义词 / 近义 相关词 / 话题 行为动词 描述词 短语 / 搭配 答案： 同义词 / 近义 mercy – kindness；withdraw – retreat；behold – see；exploit – use；opponent – rival 相关词 / 话题 sea, ocean, fleet, channel, maritime, marine, submersible, coral, migration, port 行为动词 set sail, extend, negotiate, behold, withdraw, applaud, tax, exploit, murder, arrest 描述词 royal, maritime, manned, underwater, marine, political 短语 / 搭配 set sail, in a league of one's own, withdraw from, in hand, press conference B. 易混词辨析（4组，每组3小题） 第1组：extend / extension / extensive (1) The government plans to __________ (扩展) the old port so that more ships can come in.

He joined a huge fleet of ships, and his journey helped to extend the ancient maritime trade routes across the wide blue sea. Every captain had to negotiate with the local rulers before entering a new channel, and the merchants always kept a careful record in hand. My grandfather always listened to this story with wonder and great respect, because the sea had always been a strong bond between different peoples and cultures all around the world. Such journeys were full of danger, but they also brought new ideas to every port they visited. The great sea route was truly in a league of its own in those days. When our hero behold the tall towers of the foreign city, he knew that his long voyage had reached its end, and he was warmly welcomed like a member of a higher league. The local king and his wise ministers were deeply interested in politics and trade, and he treated the merchants with mercy and respect at every meeting. He even asked the merchant about his profession and offered him a place in a grand tournament of ships. The merchant's ship was a fine mixture mixture of old and new styles, and its honest crew always kept their word, so they never had to withdraw from any agreement they had once made with their friends. In modern times, the sea still connects our world in many ways. Today a captain can sit in his cabin with a laptop, read the latest news coverage coverage of the ocean, and watch a press conference press conference online while his ship moves on. Sailors applaud the scientists who study marine life, and governments may tax the goods that cross the sea. Some teams use a manned submersible to explore the underwater world, where colourful coral forests grow and millions of colourful fish begin their long migration every year. Meanwhile, modern ships can carry thousands of gallons of fuel, and a large ship's log records every mile of the long journey across the sea. However, the sea can sometimes also be dangerous and unfair to innocent people. Some people exploit the ocean and take more than they truly need, while others may commit murder or steal the possessions of honest sailors. An opponent of justice may try to arrest innocent fishermen on false charges, and a cruel captain might treat his own crew like prisoners. But in the end, those who respect the sea will always have mercy on their side, because the ocean rewards honest people with its endless treasures, and every record in the directory of the world's seas tells the same true story of courage, hope and friendship for the future. B. 语境串记单词（汉语译文） 很久以前，我的曾祖父给我讲了一个故事(tale)：一位勇敢的商人(merchant)决定从皇城(royal)的港口起航(set sail)，把丝绸和香料(spice)运往遥远的国度。他加入了一支庞大的船队(fleet)，他的航行帮助扩展(extend)了古老的海洋(maritime)跨海贸易路线。每一位船长在进入新的航道(channel)前都必须与当地统治者谈判(negotiate)，商人们也总是把手头(in hand)的记录仔细保存。祖父满怀惊奇与敬意地听完这个故事，因为大海一直是全世界不同民族和文化之间牢固的纽带(bond)。 这条伟大的海路在当时真是独领风骚(in a league of one's own)。当我们的英雄看见(behold)异国城市的高塔时，他知道漫长的航行终于到了尽头，他受到欢迎，仿佛属于更高等级(league)的一员。当地国王对政治(politics)和贸易深感兴趣，每次会面都以仁慈和尊敬对待商人，还询问商人的职业(profession)，并邀请他参加一场盛大的船只锦标赛(tournament)。商人的船是新旧风格的巧妙混合(mixture)，诚实的船员从不食言，因此他们从不曾从(withdraw from)任何与朋友达成的协议中退出(withdraw)。 在当今时代，海洋仍然以多种方式连接着我们的世界。如今，船长可以坐在舱内，用笔记本电脑(laptop)阅读关于海洋的新闻报道(coverage)，在线观看记者招待会(press conference)，而他的船继续前行。水手们为研究海洋(marine)生物的科学家鼓掌(applaud)，政府也会对跨海的货物征税(tax)。一些团队使用载人(manned)潜水器(submersible)探索水下(underwater)世界，那里生长着色彩斑斓的珊瑚(coral)森林，每年都有数百万条鱼开始它们的迁徙(migration)。与此同时(meanwhile)，现代船只可以携带数千加仑(gallon)的燃料，船的航行日志(log)记录着漫长航程的每一英里。 然而，海洋对人们来说也可能危险而不公。有些人开发(exploit)海洋，索取超过真正所需，而另一些人可能犯下谋杀(murder)罪，或偷窃诚实水手的财物(possession)。不义的对手(opponent)可能以虚假的罪名逮捕(arrest)无辜的渔民，残暴的船长可能像对待囚犯一样对待自己的船员。但最终，尊重海洋的人总会得到仁慈(mercy)的眷顾，因为海洋用无尽的财富回报诚实的人，而世界海洋名录(directory)中的每一笔记录都讲述着同样关于勇气与希望的真实故事。 第二部分：词形转变表 序号 原词 词形变化 1 tale n.故事 teller (n.) 讲述者；tell (v.) 讲述；tales (复数)；storyteller (n.) 讲故事的人 2 extend vt.扩展 extension (n.) 扩展；extended (adj.) 延长的；extensive (adj.) 广泛的 3 negotiate vt.谈判 negotiation (n.) 谈判；negotiator (n.) 谈判者；negotiated (过去式)；negotiating (现在分词) 4 behold vt.看 beheld (过去式)；beholder (n.) 观看者；beholding (现在分词) 5 royal adj.皇家的 royalty (n.) 皇室；royally (adv.) 像王室一样 6 withdraw vi.撤回 withdrawal (n.) 撤回；withdrew (过去式)；withdrawn (过去分词)；withdrawing (现在分词) 7 maritime adj.海的 mariner (n.) 海员；marine (adj.) 海洋的；seafaring (n.) 航海 8 politics n.政治 political (adj.) 政治的；politician (n.) 政治家；politically (adv.) 政治上 9 profession n.职业 professional (adj.) 专业的；professionally (adv.) 专业地；professor (n.) 教授 10 applaud vt.鼓掌 applause (n.) 掌声；applauded (过去式)；applauding (现在分词) 11 migration n.迁徙 migrate (v.) 迁徙；migratory (adj.) 迁徙的；migrating (现在分词) 12 exploit vt.开发 exploitation (n.) 开发；exploited (过去式)；exploitable (adj.) 可开发的 13 murder vt.谋杀 murderer (n.) 谋杀犯；murderous (adj.) 凶残的；murdered (过去式) 14 mercy n.仁慈 merciful (adj.) 仁慈的；merciless (adj.) 残忍的；mercifully (adv.) 仁慈地 15 arrest vt.逮捕 arrested (过去式)；arresting (现在分词)；arrest warrant 逮捕令 第三部分：梯度复现与多题型练习 题型1：英汉互译（30题） 乐思英语 ·语境串记单词 第 10 / 10 页 学科网（北京）股份有限公司 子题A：英译中（20个） 1. tale → __________ 2. merchant → __________ 3. extend → __________ 4. negotiate → __________ 5. fleet → __________ 6. royal → __________ 7. spice → __________ 8. withdraw → __________ 9. channel → __________ 10. maritime → __________ 11. bond → __________ 12. politics → __________ 13. profession → __________ 14. tournament → __________ 15. mixture → __________ 16. coverage → __________ 17. applaud → __________ 18. migration → __________ 19. exploit → __________ 20. mercy → __________ 子题B：中译英（10个） 1. 起航 → __________ 2. 看见 → __________ 3. 等级 → __________ 4. 在手头的 → __________ 5. 笔记本电脑 → __________ 6. 记者招待会 → __________ 7. 征税 → __________ 8. 载人的 → __________ 9. 潜水器 → __________ 10. 水下的 → __________ 题型2：词形变换（15题） 1.

An old sailor told us a tale about the brave merchants of the past, who sailed across the sea to trade with foreign lands. Our teacher, an expert on marine life, told us that the sea covers most of our planet and that it connects every country in the world. She explained that the early sailors used simple tools to set sail and explore new lands, and that they had to negotiate with foreign rulers before they could trade with them. In the afternoon, we visited a science centre near the port, where we saw a real submersible used by scientists to explore the underwater world. The machine can carry two people and go down to a great depth, where the sunlight never reaches. We watched a film about the colourful coral reefs, which are home to millions of fish, and we learned how the fish begin their migration every year to find food and warm water. The centre also showed us the log book of an old ship, which recorded every mile of its long journey across the sea, and we learned that the ship had once been part of a large fleet that carried goods to many countries. The teacher also talked about the dangers that the ocean faces today. Some people exploit the sea too much and catch more fish than they need, which harms the balance of nature. She told us that the government has passed new laws to tax the large fishing boats and to protect the young fish during the breeding season. A famous scientist held a press conference to call on everyone to protect the ocean, and the audience applauded loudly after her speech. Meanwhile , the coast guards began to patrol the sea more often, and the big ships had to record every gallon of fuel they used. On our way home, we saw the coast guards arrest a man who had stolen the possessions of the fishermen at the port. Our teacher reminded us that the sea is not only a source of wealth but also a place that needs our protection and mercy. She said that every student can play a part, and that we should never treat the ocean like an opponent to be conquered, nor withdraw from our duty to protect it. Instead, we should work together to keep the sea clean and safe for all living things, because the ocean is the common home of every creature on the earth. 1. What did the students see at the science centre near the port? A. A real fishing boat. B. A large oil ship. C. A real submersible and an old ship's log book. D. A map of the world. 2. What does the underlined word "submersible" in Paragraph 2 most probably mean? A. A machine that can travel under water. B. A kind of sea bird. C. A tall building near the sea. D. A type of fishing net. 3. What can we infer from the passage? A. The students were afraid of the sea. B. The ocean faces no danger at all. C. Only adults can protect the ocean. D. We should protect the ocean and use its resources wisely. 4. What is the main idea of the passage? A. How to catch fish in the sea. B. Why the sea is dangerous. C. A science class that taught students about the ocean and the need to protect it. D. How to build a submersible. 第四部分：关联拓展与循环巩固 A. 词汇网络图（话题：Reaching Out Across the Sea） 类别 词汇 同义词 / 近义 相关词 / 话题 行为动词 描述词 短语 / 搭配 B. 易混词辨析（4组，每组3小题） 第1组：extend / extension / extensive (1) The government plans to __________ (扩展) the old port so that more ships can come in.
