洞穴
When you see 洞穴 (dòng xué), think of a cave.
It's a natural opening in the ground or side of a mountain.
People and animals can live in caves, or just visit them.
Sometimes caves are dark and mysterious, but they can also be very beautiful.
So, 洞穴 means 'cave'.
When you're talking about a natural underground space, use 洞穴 (dòngxuè). This word specifically refers to a cave, often a large one that people can explore. It's a common noun you'll hear when discussing geography, adventure, or even some folklore. Think of a dark, enclosed space in the side of a mountain or underground – that's a 洞穴. It's pretty straightforward!
When talking about caves in Chinese, you use the word 洞穴 (dòng xué). This term specifically refers to a natural underground cavity or a large hole in the side of a mountain or cliff. It's a general term you can use for various types of caves, from small hollows to extensive cavern systems. You'll often hear it in contexts related to exploration, nature, or even as a metaphorical 'hideout'.
When talking about caves in Chinese, you use the word 洞穴 (dòng xué). This is a general term for any natural underground space. You can use it to describe a small recess or a vast cavern system.
For example, you might say: 我们发现了一个巨大的洞穴 (Wǒmen fāxiàn le yí gè jùdà de dòngxué), meaning "We discovered a huge cave." Or, if you're talking about exploring them: 探险家们喜欢探索洞穴 (Tànxiǎnjiā men xǐhuān tànsuǒ dòngxué), which means "Explorers like to explore caves."
§ What does 洞穴 mean?
The Chinese word for cave is 洞穴 (dòngxué). It's a noun and it's quite straightforward. Think of it as 'hole' (洞, dòng) + 'cave/den' (穴, xué). When you put them together, you get 'cave'. Simple, right?
- DEFINITION
- 洞穴 (dòngxué): a natural underground chamber or series of chambers; a cave.
You'll hear or read 洞穴 whenever people are talking about actual caves, whether they are natural formations in mountains or even sometimes man-made ones if they resemble a natural cave. It's a very common word for this concept in Chinese. There isn't much ambiguity with it, which is good for learners.
§ When do people use 洞穴?
People use 洞穴 in pretty much the same contexts you'd use 'cave' in English. Here are some common scenarios:
- Talking about natural geographical features.
- Describing places where animals live (if it's a cave-like dwelling).
- In adventure stories or discussions about exploration.
- When discussing archaeology or ancient human habitation.
Let's look at some examples to make this super clear. Pay attention to how 洞穴 is used in different sentences.
我们发现了一个巨大的洞穴。(Wǒmen fāxiàn le yī ge jùdà de dòngxué.)
Translation hint: We discovered a huge cave.
Here, it's used to describe finding a large natural cave. Very straightforward.
蝙蝠住在洞穴里。(Biānfú zhù zài dòngxué lǐ.)
Translation hint: Bats live in caves.
This example shows 洞穴 as the habitat for animals, specifically bats, which are famously cave-dwelling creatures.
探险家们正在探索这个未知的洞穴。(Tànxiǎnjiāmen zhèngzài tànsuǒ zhège wèizhī de dòngxué.)
Translation hint: The explorers are exploring this unknown cave.
Here, it's used in the context of exploration, just like you'd talk about exploring caves in English. No tricky business.
Sometimes you might see just 洞 (dòng) used in a broader sense for 'hole', but for a distinct geological 'cave', 洞穴 is the more precise and common term. While a 'hole' can be small or large, a 'cave' implies a significant, often explorable, natural opening. So, if you're picturing stalactites and stalagmites, you're definitely thinking of a 洞穴.
The CEFR B1 level means you should be able to understand and use this word in simple, routine tasks and when exchanging information on familiar topics. Knowing 洞穴 will help you talk about nature, travel, and even animals more effectively in Chinese. It's a foundational word for describing natural environments.
Keep practicing these examples, and try to make up your own sentences. The more you use it, the more natural it will feel.
§ Basic Usage
The word 洞穴 (dòngxuè) is a noun and it directly translates to 'cave' or 'cavern'. It's pretty straightforward to use in Chinese sentences, often acting as the subject or object. Think of it just like how you'd use 'cave' in English.
- Word Type
- Noun
When you're talking about a specific cave, you can use common classifiers like 个 (gè) or 座 (zuò). While 个 (gè) is a general classifier and always safe, 座 (zuò) is often used for large, prominent structures like mountains, buildings, or indeed, large caves. Both are acceptable, but 座 (zuò) adds a bit more emphasis on the cave's size or grandeur.
他们发现了一个很大的洞穴。
- Translation Hint
- They discovered a very big cave.
这个洞穴深不见底。
- Translation Hint
- This cave is bottomless (so deep you can't see the bottom).
§ Prepositions and Locations
When you want to describe actions happening in, at, or near a cave, you'll use prepositions similar to English. The most common ones are 在 (zài) for 'in/at' and 到 (dào) for 'to/arrive at'.
他们住在洞穴里。
- Translation Hint
- They live in the cave.
Note the use of 里 (lǐ) after 洞穴 (dòngxuè) when you're talking about being *inside* the cave. This is common for locations and means 'inside'. If you're just talking about being *at* the cave, 在 (zài) + 洞穴 (dòngxuè) is fine without 里 (lǐ), but adding 里 (lǐ) clarifies the 'inside' aspect.
我们到达了洞穴的入口。
- Translation Hint
- We arrived at the entrance of the cave.
When indicating possession or a relationship, you can use 的 (de) after 洞穴 (dòngxuè), just like with other nouns.
这是动物的洞穴。
- Translation Hint
- This is the animal's cave.
§ Common Phrases and Idioms
While 洞穴 (dòngxuè) is quite literal, it can appear in some slightly more descriptive phrases. You won't find many complex idioms directly using 洞穴, but you'll see it combined with other words to form common expressions related to caves.

- 洞穴探险 (dòngxuè tànxiǎn): Cave exploration (noun phrase).
- 住在洞穴里 (zhù zài dòngxuè lǐ): To live in a cave.
他们喜欢探险洞穴。
- Translation Hint
- They like to explore caves.
§ Related Vocabulary
Understanding 洞穴 (dòngxuè) is easier when you know some related terms:
- 山洞 (shāndòng): Mountain cave. This is often used interchangeably with 洞穴 (dòngxuè) but specifically implies a cave in a mountain.
- 石灰岩洞 (shíhuīyándòng): Limestone cave. A more specific type of cave.
- 洞口 (dòngkǒu): Cave entrance/mouth of the cave.
- 洞壁 (dòngbì): Cave wall.

§ What 洞穴 Means
You're learning the word 洞穴 (dòngxuè), which means 'cave'. It's a B1 level word, so it's good to get familiar with it. When you hear this word, it's usually in discussions about nature, adventure, or sometimes in a more metaphorical sense. Let's break down how you'll encounter it.
- DEFINITION
- 洞穴 (dòngxuè): cave
§ In Everyday Talk and News
You'll often hear 洞穴 when people are talking about natural formations, especially if they're discussing travel, hiking, or geography. Think about documentaries, news reports about discoveries, or even just casual conversations about places to visit.

Translation hint: This park has several caves, very suitable for exploration.

§ More Formal and Academic Contexts
While 'cave' might sound simple, 洞穴 can also appear in more formal or academic settings, especially when discussing geology, archaeology, or even environmental science. For example, you might read about ancient artifacts found in a cave or the unique ecosystem within a cave.
科学家正在研究这个洞穴的形成过程。(Kēxuéjiā zhèngzài yánjiū zhège dòngxuè de xíngchéng guòchéng.)

§ Metaphorical Uses
Occasionally, 洞穴 can be used metaphorically, especially in literature or more descriptive writing. It might refer to a hidden or secluded place, or even a deep, dark recess of something abstract.
A quiet, private spot: Think of someone retreating to their 'cave' for some peace.
A place of secrecy: Where secrets are kept hidden.
However, for B1 level learning, focus on its literal meaning first. The metaphorical uses will become clearer as your Chinese progresses.
他把自己关在一个黑暗的洞穴里，不与外界接触。(Tā bǎ zìjǐ guān zài yī gè hēi'àn de dòngxuè lǐ, bù yǔ wàijiè jiēchù.)
Translation hint: He shut himself in a dark cave, not contacting the outside world.
By understanding these different contexts, you'll be much better equipped to understand and use 洞穴 naturally in your Chinese conversations and readings.
Let's look at 洞穴 (dòngxuè) and other words that also mean 'cave' or something similar in Chinese. Understanding the differences will help you use them correctly.
§ 洞穴 (dòngxuè): The standard 'cave'
When you just mean a natural hollow in the side of a hill or cliff, 洞穴 (dòngxuè) is usually your best choice. It's a very common and neutral term.
- DEFINITION
- cave; grotto
我们发现了一个巨大的洞穴。
Translation hint: We discovered a huge cave.
这个洞穴里住着蝙蝠。
Translation hint: Bats live in this cave.
§ 洞 (dòng): Simpler, broader meaning
洞 (dòng) is a more general term for 'hole' or 'cave'. It can refer to any kind of hole, big or small, natural or man-made. You can use it for a cave, but it's less specific than 洞穴 (dòngxuè).
- DEFINITION
- hole; cave; burrow
墙上有一个洞。
Translation hint: There's a hole in the wall.
那个洞很深。
Translation hint: That hole/cave is very deep.
§ 溶洞 (róngdòng): Karst caves
If you're talking about a specific type of cave formed in soluble rock like limestone, then 溶洞 (róngdòng) is the word you need. These are often famous tourist attractions with stalactites and stalagmites.
- DEFINITION
- karst cave; solution cave; limestone cave
桂林的溶洞很美。
Translation hint: The karst caves in Guilin are very beautiful.
他们正在探索新的溶洞。
Translation hint: They are exploring new karst caves.
§ 窑洞 (yáodòng): Man-made cave dwellings
This word is very specific. 窑洞 (yáodòng) refers to a cave dwelling, typically carved out of a loess cliff, often found in parts of northern China. These are homes, not natural geological formations.
- DEFINITION
- cave dwelling; yaodong
许多农民住在窑洞里。
Translation hint: Many farmers live in cave dwellings.
延安有很多历史悠久的窑洞。
Translation hint: Yan'an has many historic cave dwellings.
§ When to use which word
Here's a quick guide:
- 洞穴 (dòngxuè): Your default for 'cave'. Use it for natural caves in general.
- 洞 (dòng): Use when 'hole' is also appropriate, or for a very general 'cave'. It's less precise for natural caves.
- 溶洞 (róngdòng): Use specifically for karst or limestone caves, often those with stalactites/stalagmites.
- 窑洞 (yáodòng): Use only for traditional Chinese cave dwellings, which are man-made homes.
By understanding these differences, you can choose the most accurate word for 'cave' in Chinese depending on the context. Don't be afraid to stick with 洞穴 for most situations until you're confident with the more specific terms.
How Formal Is It?
"这个省份有许多壮丽的石灰岩溶洞，吸引着地质学家和游客 (This province has many magnificent limestone caves, attracting geologists and tourists)."
"探险家们发现了一个新的地下洞穴系统，里面有独特的生物 (Explorers discovered a new underground cave system with unique organisms inside)."
"小时候我们经常在后山的山洞里玩捉迷藏 (When we were little, we often played hide-and-seek in the mountain cave behind our house)."
"小熊住在一个暖和的山洞里，冬天就不怕冷了 (The little bear lives in a warm mountain cave, so it's not afraid of the cold in winter)."
"警察终于找到了犯罪团伙的老巢，把他们一网打尽 (The police finally found the criminal gang's lair/den and caught them all in one swoop)."
Le savais-tu ?
The character '洞' can also mean 'to penetrate' or 'to understand thoroughly', as in '洞察' (dòngchá - insight).
Guide de prononciation
- Tones: Ensure the falling tone on 'dòng' and the rising tone on 'xué' are distinct. Many learners flatten tones.
- Pronunciation of 'x': The 'x' in 'xué' is a voiceless alveolo-palatal fricative, similar to the 'sh' in 'she' but with the tongue tip further forward and the back of the tongue raised. It's often mispronounced as an 's' sound.

neutralFacile à confondre
Both '洞穴' and '山洞' refer to a cave. Learners might wonder if there's a difference in their usage or nuance.
'洞穴' is a more general and formal term for any type of cave, grotto, or hole. '山洞' specifically refers to a cave in a mountain. While '山洞' is a type of '洞穴', not all '洞穴' are '山洞'. '山洞' is more commonly used in everyday speech when talking about mountain caves.
这个山洞深不见底，里面可能住着蝙蝠。 (This mountain cave is bottomless, bats might live inside.)
Visually, '洞' is part of both words, and '口' can mean mouth or opening. Learners might confuse it with the entire cave.
'洞口' refers specifically to the entrance or opening of a cave, hole, or tunnel. It's not the cave itself, but the access point to it.
我们站在洞口，往里面张望。 (We stood at the cave entrance, peering inside.)
'孔' also means a hole. Learners might be unsure when to use '孔' versus '洞穴'.
'孔' usually refers to a small hole, aperture, or opening, like a buttonhole, a nostril, or a keyhole. '洞穴' implies a larger, often natural, cavity or space that a person or animal could enter or inhabit. You wouldn't use '洞穴' for a small hole in a shirt.
衣服上有一个小孔。 (There's a small hole in the clothes.)
'穴' is a component of '洞穴' and also means a hole or den, which can be confusing for its standalone meaning.
While '穴' can mean a cave, den, or burrow, it's often used in more specific contexts or as part of compound words like '洞穴'. When used alone, it often refers to an animal's den or a smaller, less grand cavity than what '洞穴' typically implies. '洞穴' is the more common and general term for a cave.
狐狸住在洞穴里。 (Foxes live in dens.) (Note: '洞穴' here refers to a den, emphasizing the general cavity.)
'坑' also means a pit or hole, which can lead to confusion with '洞穴'.
'坑' typically refers to a pit, hollow, or depression in the ground, often man-made or formed by an impact. It's usually open at the top and doesn't extend horizontally like a cave. '洞穴' implies an enclosed or partially enclosed space, often extending deeper into the earth or a mountain.
路上有一个大坑。 (There's a big pit on the road.)

洞穴探险是一项充满刺激但也伴随高风险的活动。在探险前，充分的准备至关重要。首先，必须组建一个经验丰富的团队，并确保每个人都了解洞穴的基本情况。其次，检查所有装备，包括头灯、备用电池、绳索、急救包和通讯设备，确保它们完好无损。制定详细的探险路线和应急预案也必不可少。探险过程中，务必保持警惕，注意脚下和头顶，避免触碰不明物体。遵循团队领导的指示，不要单独行动，并随时与队友保持联系。在遇到紧急情况时，冷静应对，优先保障人员安全。探险结束后，仔细检查所有人员和装备是否安全返回。同时，我们也要牢记环境保护，不留下任何垃圾，不破坏洞穴的自然生态。只有做好这些，才能真正享受洞穴探险的乐趣。

根据文章，以下哪项不是洞穴在现代社会的主要功能？
Read this passage:
在古代，洞穴不仅是人类躲避风雨、抵御野兽的天然庇护所，更是早期文明的摇篮。许多考古发现表明，史前人类在洞穴中留下了丰富的岩画和工具，这些都是研究人类起源和进化的宝贵资料。然而，随着人类社会的发展，洞穴的实用功能逐渐减弱，但其独特的地理形态和生态环境仍然吸引着无数科学家和探险家前往探索。现代洞穴探险活动不仅有助于我们了解地球的内部构造，也为生物学家提供了研究极端环境下生命演化的独特视角。此外，一些经过开发的洞穴也成为了著名的旅游景点，为人们提供了亲近自然、感受历史的机会。

以下哪项最能概括洞穴生态系统的特点？
Read this passage:
洞穴生态系统是一个独特而脆弱的环境。由于缺乏阳光，光合作用无法进行，因此洞穴食物链的基石是外部输入的有机物，或是化学自养微生物。许多洞穴生物，如盲鱼、洞穴虾和一些昆虫，都进化出了独特的适应性，例如失去色素、视力退化，但感官却异常敏锐，以适应黑暗的环境。这些生物对温度、湿度和营养物质的变化非常敏感，即使是微小的环境扰动也可能对它们造成毁灭性的影响。因此，在洞穴探险和旅游活动中，保护洞穴的原始生态环境至关重要，避免引入外来物种，减少噪音和污染，以维护这些独特生物的生存空间。
以下哪项最能概括洞穴生态系统的特点？
文章中描述了洞穴生态系统因缺乏阳光而独特，生物进化出适应性但对环境变化非常敏感，并且强调了其脆弱性，因此这个选项最能概括其特点。
