In 1866, a terrible sea creature is seen by several ships. Biologist Professor Pierre Aronnax and his servant, Conseil, join a ship to find and kill the creature. After a long journey into the Pacific Ocean, the creature is finally seen. While attacking from the ship,Aronnax and Conseil, along with the whale hunter Ned Land, fall into the sea, and discover that the “creature" is actually a submarine.They are captured and taken inside the submarine, where they meet the man in charge, Captain Nemo. Ahead of its time, the submarine is also a secret from the rest of the world. In order to keep this secret,Captain Nemo tells his three newest passengers that they are not permitted to leave the submarine.While Ned Land can think only of escaping, Aronnax and Conseil are fascinated by their adventures in the new underwater world. In this part adapted from a chapter of the book, Aronnax describes the experience of walking on the sea bed...

How did Aronnax feel about his equipment underwater

解析：
定位原文：“I no longer felt the weight of my clothes, or of my shoes, of my air supply, or my thick helmet...”
逻辑推导：“no longer felt the weight”→ 装备仿佛 “失重”。
答案：B
其后的定语从句inside which my head shook like a nut in its shell是对helmet进行解释说明，这样我们可推测其词义为“头盔”。
2. I no longer felt the weight of my clothes, or of my shoes, of my air supply, or my thick helmet, inside which my head shook like a nut in its shell.
词义猜测题
What does “helmet” probably mean in the text
核心规律速记
1. 结构公式：
介词 + which/whom（指物用which，指人用whom）
例：The book on which I spent $10 is useful. （对应动词搭配：spend money on sth.）
2. 介词选择三原则：
看动词：从句中动词与介词的固定搭配（如depend on, listen to）
看先行词：先行词与介词的习惯搭配（如in the room, on Monday）
看句意：通过上下文逻辑判断（如表示“所属”用of）
3. 关系副词转换：
when = 介词 + which（时间）
the day on which we met = the day when we met
where = 介词 + which（地点）
the city in which I live = the city where I live
why = for which（原因）
the reason for which he left = the reason why he left
介词+关系词
经典习题精练
1. 单选题
① The man ______ you shook hands is my boss.
A. whom B. with whom C. to whom
② The house ______ windows face south is very expensive.
A. whose B. of which C. which
2. 填空题（用“介词+which”填空）
③ The school ______ I studied for 3 years has closed.
④ The reason ______ he was late is clear.
B
A
in which
for which
动词短语不可拆分：
如look after不可拆为after which，应说the baby whom you look after。
非限制性定语从句：
逗号后只用which/whom，不用that。
例：He gave me a book, from which I learned a lot.
部分与整体结构：
用“数词/代词 + of + which/whom”。例：I have 3 books, two of which are novels.
通过“动词搭配+先行词+句意”三角度快速判断，结合关系副词转换规律，1分钟内即可掌握核心用法！
高频易错点总结
Read the passage carefully to understand each word and each sentence’s meaning.
How many sentences are there
Read the passage carefully to understand each word and each sentence’s meaning.
1.猜测词义：一、构词法；二、定义或解释；三、上下文语境。
2.长难句分析方法
长难句分析方法
一、三步拆解法：抓主干→拆修饰→理逻辑
精简口诀（便于记忆）
“先去插入语，再分主谓语；
从句分层拆，逻辑词标记；
翻译先主干，修饰往后续；
每天练五句，阅读无阻力！”
翻译原则：
1. 先译主干，再译修饰（从句拆成短句，介词短语提前）；
2. 逻辑词（because/although）优先翻译，明确因果/让步关系。
示例重组：
“Although tired, she kept studying until midnight to prepare for the exam.”
翻译：尽管很累，她还是一直学习到深夜，为考试做准备。
1. 第一步：秒找主干——锁定“谁做了什么”
2. 第二步：快拆修饰——分层标记从句/短语
3. 第三步：梳理逻辑——用中文“顺译”重组
二、高中必考长难句结构及破题技巧
1. 插入语分隔（用逗号/破折号隔开）
例：The result, in my opinion, is not surprising.
破题：直接跳过插入语in my opinion，主干为The result is not surprising.
2. 定语从句套叠（从句中含从句）
例：The city that I visited last year, which lies in the south, has developed rapidly.
破题：先找第一层从句that I visited last year（修饰city），再找第二层从句which lies in the south（补充说明city）。
3. 否定转移与双重否定
否定转移：I don’t think he is wrong.（实际否定“he is wrong”）；
双重否定：No one can deny the importance of practice.（= 所有人都承认练习的重要性）。
4. 强调句与倒装句
强调句：It is science that changes our life.（还原：Science changes our life.）；
倒装句：Hardly had he arrived when it rained.（还原：He had hardly arrived when it rained.）。
题目 7：细节理解题
What was the sand like on the sea bed
A. Rough and dirty. B. Fine and smooth.
C. Wet and soft. D. Thick and heavy.
题目 8：词义猜测题
What does “vibration” refer to in the text
A. The movement of water atoms.
B. The sound of the submarine.
C. The reflection of the sun.
D. The weight of the equipment.
解析：定位原文：“We were walking on fine, even sand, not wrinkled, as on a flat shore...”
关键信息：“fine, even sand”→ 细腻、平整（smooth）。
解析：定位原文：“...which accounted for the vibration which passed through every atom of liquid.”
逻辑推导：前文提 “沙子像反光镜，驱散阳光”，导致液体原子的 “震动”。
B
A
题目 9：深层理解题
What does the author’s detailed description of the underwater light suggest
A. The limitations of human vision underwater.
B. The magical and extraordinary nature of the underwater world.
C. The superiority of the submarine’s lighting system.
D. The danger of strong sunlight underwater.
解析：文中对水下光线 “astonished me by its power” “I could see as if I was in broad daylight” 等描述，突出水下世界光线奇特，展现其神奇非凡，并非强调人类视觉局限、潜艇照明优越或水下阳光危险。
题目 10：写作意图题
Why does the author compare the underwater sand to “a dazzling carpet” and “a reflector”
A. To emphasize(强调）the texture（质地） of the sand.
B. To illustrate（说明） the practical use of the sand on the sea bed.
C. To convey（传达） the unique and beautiful appearance of the underwater environment.
D. To show the similarity between the sea bed and the land.
解析：将海底沙子比作 “dazzling carpet” 和 “reflector”，通过比喻生动描绘其闪亮、反射阳光的特点，意在展现水下环境独特美丽，而非强调沙子质地、实际用途或海床与陆地相似性。
B
C
题目 11：文章主旨题
Which of the following best summarizes the main idea of the adapted passage
A. The technical features of Captain Nemo’s submarine.

D. Ned Land’s attempts to escape from the submarine.
题目 12：推理判断题
How did Aronnax feel about the underwater world
A. Bored. B. Frightened. C. Amazed. D. Disappointed.
C
解析：定位原文：“Words are not enough to relate such wonders!”（语言无法描述奇迹）→ 表达 “惊叹”。
C
解析：文章前半部分介绍三人落水及被困潜艇的背景，后半部分重点是阿龙纳斯对海底行走体验的生动描述，核心是其水下冒险与神秘海底世界，选项 A、B、D 并非文章主旨。
A. Indifferent B. Fearful C. Critical D. Enthusiastic
D
1.主句是 “The light astonished me by its power”（主语：The light；谓语：astonished；宾语：me；方式状语：by its power ）。
To learn the sentence structures.
which 引导的非限制性定语从句，修饰先行词 “The light” ，其中 “thirty feet below the surface of the ocean” 是 “the soil” 的后置定语，说明土壤的位置。
翻译：那束光线能照亮海洋表面以下三十英尺处的海底，其威力令我惊叹。

这是一个倒装句，正常语序
The calm surface of the sea was above me
5. Above me was the calm surface of the sea.”
翻译：在我上方的是平静的海面。
（主语：The calm surface of the sea；谓语：was；表语：above me ），

6. We were walking on fine, even sand, not wrinkled, as on a flat shore, which keeps the impression of the waves.
“not wrinkled” 是形容词短语作 “sand” 的后置定语，补充说明沙子的状态 。

“really a reflector” 是同位语，对 “This dazzling carpet” 进行补充说明 。
第一个 “which” 引导非限制性定语从句，修饰前面整个主句内容；第二个 “which” 引导定语从句，修饰 “the vibration” 。
翻译：这片耀眼的沙地，就像一面反光镜，以惊人的强度反射着太阳光，这就解释了为什么海水的每一个水分子都在振动。
主句：“Shall I be believed”（主语：I；谓语：shall be believed，是被动语态 ）。
8. Shall I be believed when I say that, at the depth of thirty feet, I could see as if I was in broad daylight
“when I say that...” 是时间状语从句，其中 “that” 引导宾语从句，作 “say” 的宾语；“at the depth of thirty feet” 是 “in broad daylight” 中 “see” 这一动作发生的地点状语；“as if I was in broad daylight” 是方式状语从句，说明 “see” 的状态 。
翻译：当我说在三十英尺的深处，我能看得像在大白天一样清楚时，有人会相信我吗？
