توضیح 锐减 in your Level:

At the A1 level, you are just starting your Chinese journey. '锐减' (ruìjiǎn) is a bit advanced for this stage, but you can understand it by breaking it down. Think of '减' (jiǎn), which means 'minus' or 'to take away,' like in simple math (5 - 2 = 3). The '锐' (ruì) part makes it special—it means 'sharp' like a knife. So, 锐减 means something goes down very fast, like a sharp drop. You might not use this word yourself yet, but you might see it in a simple news headline about a city having fewer people or a shop having fewer customers. At A1, focus on the 'down' part. If you see '锐减,' something is becoming much, much smaller very quickly. It's like the opposite of '增加' (zēngjiā - to increase). Even if you can't say long sentences with it, knowing that it means 'a big drop' will help you understand more difficult texts later on. For now, just remember: 锐 = sharp, 减 = less. Together, they mean a sharp drop. This word is more formal than the words you usually learn in A1, like '少' (shǎo - few/less). Using 锐减 makes you sound very smart, even if you only know a few words!

As an A2 learner, you are building your vocabulary for everyday life. '锐减' (ruìjiǎn) is a word you might start to encounter in simplified news stories or intermediate listening materials. While '减少' (jiǎnshǎo) is the word you probably use most often to say 'decrease,' 锐减 adds more 'feeling' to the sentence. It tells the listener that the decrease was not just a little bit, but a lot. For example, if you are talking about a forest and many trees are cut down quickly, you can say the trees '锐减'ed. In A2, you should start noticing that Chinese uses two-character words to be more specific. '锐' acts like an adverb here. You can practice by comparing it to things you know: '减少' is like 'going down the stairs,' but '锐减' is like 'jumping off the stairs.' It's much faster! You will mostly see this used with numbers, like '人数' (number of people) or '钱' (money). If a company loses a lot of money fast, their profit '锐减.' Try to recognize this word when you read about the environment or the economy in your Chinese textbooks. It's a great 'bridge' word to help you move from basic Chinese to more professional-sounding Chinese.

At the B1 level, you are expected to handle more complex topics like the environment, work, and social issues. '锐减' (ruìjiǎn) is a perfect word for this level. It is a 'formal' verb. You will use it when writing essays or giving presentations about serious topics. For example, if you are writing about climate change, you wouldn't just say 'water is less'; you would say 'water resources are 锐减-ing.' This word shows that you understand 'register'—the difference between talking to a friend and writing a report. Grammatically, remember that 锐减 is usually the main verb of the sentence. You can say '数量锐减' (The quantity decreased sharply). You can also add '了' (le) to show it already happened: '利润锐减了百分之五十' (Profits decreased sharply by 50%). At B1, you should also be careful not to use it for emotions. You don't '锐减' your love for someone! It's for things you can count or measure. Learning 锐减 will help you transition from HSK 3 level Chinese to HSK 4 and 5, where formal vocabulary becomes much more important. It is a very common word in the 'Reading' section of the HSK exams, so being able to identify it quickly as a 'sharp decrease' will save you time.

At the B2 level, you should be able to use '锐减' (ruìjiǎn) with precision and understand its nuances compared to similar words. You should know that 锐减 specifically implies a 'sharp' and 'rapid' decline. In your writing, you can use it to create a sense of urgency or to highlight a significant problem. For instance, in a business context, you might discuss how a '锐减' in sales led to a change in strategy. You should also be comfortable using it in the '锐减至' (decreased sharply to) and '锐减了' (decreased sharply by) structures, which are essential for accurate reporting. B2 learners should also recognize that 锐减 is an intransitive verb. You wouldn't say 'The government 锐减 the budget.' Instead, you would say 'The budget 锐减-ed due to government cuts.' This distinction between active and passive-style structures is a hallmark of B2 proficiency. You might also start to see 锐减 used as a noun, like in '物种数量的锐减' (the sharp decrease in the number of species). At this level, you can also compare it to '骤减' (zhòujiàng - sudden decrease), noting that 锐减 often feels more like a statistical or physical drop, while 骤减 focuses on the unexpected timing of the drop.

For C1 learners, '锐减' (ruìjiǎn) is a standard part of your academic and professional lexicon. You should be able to use it fluently in complex sentence structures and understand its rhetorical impact. In C1-level texts, 锐减 is often used to describe systemic failures or major demographic shifts. You should look for it in the context of '人口红利锐减' (the sharp decrease of the demographic dividend) or '生态多样性锐减' (the sharp decrease in ecological diversity). At this level, you can also appreciate the etymological roots of the word—how the 'sharpness' of '锐' provides a visual metaphor for a steep line on a graph. You should also be able to distinguish 锐减 from more specialized terms like '暴跌' (bàodiē), which is restricted to financial markets, or '萎缩' (wěisuō), which implies a more organic shrinking or withering. A C1 speaker uses 锐减 to provide a clear, professional assessment of a situation without needing to rely on simpler, less precise words like '大减.' You should also be aware of the word's usage in historical or literary contexts where it might describe the sudden decline of a dynasty's power or a city's influence, though its primary home remains in modern socio-economic and scientific discourse.

At the C2 level, '锐减' (ruìjiǎn) is a word you not only use correctly but also one whose absence you might notice in a text that requires it. You understand that 锐减 carries a specific weight of gravity. In high-level policy analysis or philosophical discourse, you might use 锐减 to discuss the '锐减' of traditional values in the face of globalization or the '锐减' of privacy in the digital age, moving slightly beyond purely quantifiable subjects into more abstract but still 'measurable' sociological trends. You are also proficient in using 锐减 within sophisticated rhetorical devices, such as parallelism or contrast: '虽然投入在增加，但产出却在锐减' (While investment is increasing, output is sharply decreasing). You understand the subtle difference in 'flavor' between 锐减 and synonyms like '削减' (which implies a deliberate act of cutting) and can choose the one that fits the exact intent of your prose. At C2, you might also use 锐减 in its noun form to anchor complex noun phrases that serve as the subject of intricate, multi-clause sentences. Your mastery of 锐减 reflects a deep integration of formal Mandarin into your cognitive framework, allowing you to discuss global crises and complex data sets with the same ease as a native-speaking expert.

锐减 در ۳۰ ثانیه

锐减 is a formal Chinese verb meaning to decrease sharply and rapidly, often used in news, business, and environmental reports to describe significant drops.
The word combines '锐' (sharp) and '减' (decrease), creating a vivid image of a steep, knife-like plunge in numbers or quantifiable amounts.
It is primarily an intransitive verb, meaning the subject (like population or profit) performs the action of decreasing sharply by itself.
Commonly paired with percentages (锐减了50%) or results (锐减至危险水平), it is essential for HSK 5+ learners and professional communication.

The Chinese term 锐减 (ruìjiǎn) is a powerful verb used to describe a situation where a quantity, number, or level does not just go down, but does so with extreme speed and significant magnitude. It is the linguistic equivalent of a cliff-edge drop. The first character, 锐 (ruì), originally refers to the sharpness of a blade or a point. In this context, it acts as an adverbial modifier implying 'sharpness' in terms of intensity and speed. The second character, 减 (jiǎn), simply means to subtract or decrease. When combined, they create a vivid image of a line graph plunging downward. This word is not typically used for minor fluctuations or slow declines; it is reserved for dramatic shifts that often carry a sense of urgency, alarm, or significant impact.

Formal Contexts: You will most frequently encounter 锐减 in news reports, academic papers, and financial analysis. It is the standard way to describe a sudden loss in biodiversity, a crash in stock prices, or a demographic crisis where birth rates fall off a cliff.

由于环境污染，这个地区的鸟类数量锐减了百分之五十。 (Due to environmental pollution, the number of birds in this region has decreased sharply by fifty percent.)

Understanding the nuance of 'sharpness' is key. Imagine a knife cutting through a piece of paper—that is the '锐' in the decrease. It suggests a lack of resistance and a rapid progression. In socio-economic discussions, 锐减 is used to highlight problems. For instance, if a company's profits 锐减, it implies a crisis that requires immediate attention. It is rarely used in a positive light unless the thing decreasing is something negative, such as 'crime rates' (though even then, words like '骤降' or '大幅下降' are more common for positive trends).

Statistical Usage: In statistics, 锐减 is often paired with specific percentages or timeframes. For example, '利润锐减三成' (Profits dropped sharply by 30%). This provides a quantitative backbone to the qualitative 'sharpness' of the word.

全球气候变暖导致北极冰川面积锐减。 (Global warming has led to a sharp decrease in the area of Arctic glaciers.)

Visualizing the Word: Think of a mountain climber slipping and falling down a steep slope. The '锐' represents the steepness of the slope, and '减' is the loss of altitude. It is a word that demands attention and usually signals that something has gone wrong in a system or environment.

In summary, 锐减 is a high-level vocabulary word that distinguishes a fluent speaker from a beginner. It allows you to express not just 'less,' but 'drastically less in a very short time.' Whether you are discussing the economy, the environment, or social trends, using 锐减 correctly demonstrates an understanding of both Mandarin semantics and the gravity of the situation being described.

Using 锐减 (ruìjiǎn) correctly involves understanding its grammatical role as an intransitive verb that functions primarily as a predicate. It describes the action of a subject (usually a noun representing a quantity or population) decreasing. Because the meaning of 'sharpness' and 'speed' is already embedded in the word, you rarely need to add additional adverbs like '很' (very) or '非常' (extremely) before it, although you can use '大幅' (dàfú - by a large margin) for extra emphasis.

Structure: Subject + 锐减: This is the most basic and common structure. The subject must be something quantifiable. Common subjects include 数量 (quantity), 人口 (population), 利润 (profit), 产量 (output), and 收入 (income).

受疫情影响，该航空公司的乘客人数锐减。 (Affected by the pandemic, the number of passengers for this airline decreased sharply.)

A more advanced way to use 锐减 is to specify the extent of the decrease using the pattern '锐减了 + [Quantity/Percentage]' or '锐减至 + [Resulting Amount]'. The '了' indicates the completion of the drop, while '至' (zhì) indicates the final point reached after the drop.

Structure: 锐减了 vs. 锐减至: '锐减了百分之三十' means it dropped BY 30%. '锐减至百分之三十' means it dropped TO 30% (a 70% loss). Choosing the right preposition is crucial for accuracy in business and scientific reporting.

该工厂的年产量从一万台锐减至三千台。 (The factory's annual output sharply decreased from 10,000 units to 3,000 units.)

Furthermore, 锐减 can be used as a noun in formal writing, often preceded by an adjective or a possessive. For example, '人口的锐减' (the sharp decrease in population). This allows for more complex sentence structures where the decrease itself is the subject of another action, such as '人口的锐减引起了政府的关注' (The sharp decrease in population has drawn the government's attention).

Temporal Modifiers: Because 锐减 implies speed, it is often paired with time phrases like '近年来' (in recent years), '短时间内' (within a short time), or '一夜之间' (overnight) to emphasize the suddenness of the event.

这种濒危动物的数量在过去十年中锐减。 (The population of this endangered animal has decreased sharply over the past ten years.)

In summary, when using 锐减, focus on the subject and the resulting change. It is a precise tool for describing significant downward trends. Avoid using it for things that cannot be measured, such as 'friendship' or 'happiness,' where more abstract verbs like '淡化' or '消减' would be appropriate. Stick to numbers, resources, and populations for the most natural usage.

You are unlikely to hear 锐减 (ruìjiǎn) in a casual conversation at a coffee shop or while hanging out with friends, unless those friends are discussing serious topics like the stock market or climate change. Instead, 锐减 is a staple of 'Formal Mandarin.' It lives in the world of professional reporting, academic inquiry, and serious journalism. If you turn on the news in China, particularly financial news or environmental specials, you will hear this word within minutes.

Financial News and Markets: On channels like CCTV-2 (Finance), anchors use 锐减 to describe market crashes or company earnings reports. Phrases like '成交量锐减' (trading volume decreased sharply) or '净利润锐减' (net profit decreased sharply) are common when a sector is underperforming.

由于市场竞争激烈，该品牌的市场占有率锐减。 (Due to fierce market competition, the market share of this brand has decreased sharply.)

In the realm of environmental science and documentaries (think the Chinese version of 'Planet Earth'), 锐减 is the standard term for the loss of natural resources. Whether it is the '锐减' of forest cover, water levels in the Yangtze River during a drought, or the population of Siberian tigers, the word conveys the tragedy and severity of the loss. It acts as a linguistic red flag for ecological disaster.

Government Reports and White Papers: Official documents from the Chinese government often use 锐减 when addressing social challenges. For example, a report on the '锐减' of the labor force (劳动力锐减) might be used to justify new policies on retirement age or birth incentives.

报告指出，该地区的降雨量较往年锐减。 (The report pointed out that the rainfall in this region has decreased sharply compared to previous years.)

Academic Lectures: In university settings, professors in economics, sociology, and biology use 锐减 to discuss trends. It is an essential word for HSK 5 and HSK 6 students who need to understand lecture content or write academic essays in Chinese.

Finally, you might see 锐减 in headlines on news apps like Toutiao or in newspapers like the People's Daily. Headlines love 锐减 because it is punchy, dramatic, and fits into the character-limited space of a mobile notification while still conveying a massive amount of information about the severity of a trend. When you see it, you know the story is about a major decline.

While 锐减 (ruìjiǎn) is a precise term, its specificity makes it easy for learners to misapply. The most common error is using it in contexts that are too informal or for decreases that are not actually 'sharp' or 'rapid.' Understanding these pitfalls will help you sound more like a native speaker and less like a textbook.

Mistake 1: Using it for Abstract or Emotional Concepts: You cannot use 锐减 to describe a decrease in feelings, interest, or abstract qualities. For example, saying '我对他的兴趣锐减' (My interest in him decreased sharply) sounds very strange and overly clinical. Instead, use '大减' (dàjiǎn) or '骤降' (zhòujiàng) if you must be dramatic, or simply '减少' (jiǎnshǎo).

Wrong: 我们的友谊锐减了。 (Our friendship decreased sharply.)
Right: 我们的友谊变淡了。 (Our friendship has faded.)

Another frequent mistake is failing to distinguish between 锐减 and other words for 'decrease.' For instance, 递减 (dìjiǎn) means a gradual, step-by-step decrease, which is the opposite of the sudden drop implied by 锐减. Using 锐减 to describe a slow, multi-decade trend that isn't particularly steep is a misuse of the word's inherent intensity.

Mistake 2: Incorrect Transitive Usage: Learners often try to say 'The government 锐减-ed the budget.' In Chinese, you cannot use 锐减 this way. The budget is the subject that 锐减s. If you want to say the government cut the budget, use '削减' (xuējiǎn) or '大幅减少' (dàfú jiǎnshǎo).

Wrong: 公司锐减了开支。 (The company sharply decreased expenses.)
Right: 公司的开支锐减。 (The company's expenses decreased sharply.)

Mistake 3: Redundancy: Avoid saying '快速地锐减' (rapidly decrease sharply). The '锐' already implies speed. While it's not strictly grammatically wrong, it's redundant and sounds clumsy to native ears. Let the word do the heavy lifting of the description.

Finally, be careful with the register. Using 锐减 in a very casual text message to a friend about your battery percentage might come across as melodramatic or humorous. '我的电量锐减' sounds like a line from a sci-fi movie or a formal report on battery technology. In daily life, '没电了' or '掉电很快' is much more natural.

To truly master 锐减 (ruìjiǎn), you must understand its relationship with other 'decrease' words in Mandarin. The Chinese language has a rich vocabulary for expressing decline, each with a specific nuance of speed, scale, and formality. Here is how 锐减 compares to its closest cousins.

锐减 vs. 骤减 (zhòujiǎn): These two are very similar and often interchangeable. However, 骤减 emphasizes the 'suddenness' (骤 means sudden) even more than the 'sharpness.' 锐减 is more common in statistical and economic reports, while 骤减 is often used for natural phenomena like a sudden drop in temperature or rainfall.

气温骤减，大家要注意保暖。 (The temperature dropped suddenly; everyone should stay warm.)

锐减 vs. 暴跌 (bàodiē): 暴跌 is specific to 'falling' (跌). It is almost exclusively used for stock prices, housing prices, or currency values. 锐减 is broader and can apply to quantities like 'population' or 'water levels' where 'falling' might not be the most accurate metaphor.

锐减 vs. 削减 (xuējiǎn): The key difference here is agency. 削减 is a transitive verb, meaning someone (a person, a government, a company) is actively cutting something down. 锐减 is an intransitive verb, describing the state of the decrease itself. You '削减' (cut) the budget, and as a result, the budget '锐减' (sharply decreases).

政府决定削减军费开支。 (The government decided to cut military spending.)

锐减 vs. 减少 (jiǎnshǎo): 减少 is the generic, neutral term. It can be a little or a lot, fast or slow. 锐减 is a subset of 减少 that specifies 'a lot' and 'fast.' If you are unsure, 减少 is always safe, but 锐减 is more descriptive and professional.

Other alternatives include 大减 (dàjiǎn), which is slightly more informal, and 缩减 (suōjiǎn), which implies a shrinking or contraction (often used for space, time, or staff numbers). By choosing the right word from this list, you can convey the exact nature of the decline you are describing, whether it is a sudden crash, a deliberate cut, or a gradual erosion.

نکات

Think of a Graph

If the line on a graph goes straight down like a slide, that's 锐减. Use it for data-driven descriptions.

Don't add 'Very'

Avoid saying '很锐减.' The 'sharp' part of the word already means 'very much.' Just say '锐减' or '大幅锐减.'

Environment and Money

These are the two biggest areas for 锐减. If you're talking about nature or finance, this word is your best friend.

Retroflex R

Make sure your tongue is curled back for the 'r' in 'Ruì.' If it sounds like 'Wui,' it's wrong.

Character Tip

The character 锐 has the metal radical. Think of a sharp metal blade cutting the numbers down.

锐减 vs 减少

Always use 锐减 instead of 减少 in formal writing if the drop is significant. It makes you sound much more professional.

至 vs 了

Remember: 锐减了 = dropped BY. 锐减至 = dropped TO. Getting this wrong changes your data completely!

Formal Only

Keep 锐减 for your essays, news watching, and business meetings. Use '变少' for chatting with friends.

Razor Minus

Ruì = Razor, Jiǎn = Minus. A razor-sharp minus!

Check the Subject

Before using 锐减, ask: 'Can I count or measure this?' If yes, go ahead. If no, pick a different word.

حفظ کنید

روش یادسپاری

Think of a '锐' (Ruì) as a 'Razor'—it's sharp. '减' (Jiǎn) sounds like 'Jan' in 'January,' but it means 'Minus.' So, 'Razor Minus' = a sharp, cutting decrease.

تداعی تصویری

Imagine a line graph that looks like a steep mountain peak, and then a knife (锐) cuts the line so it falls straight down (减).

数量 (Quantity) 利润 (Profit) 人口 (Population) 资源 (Resources) 锐减 (Sharp Decrease) 暴跌 (Crash) 骤减 (Sudden Drop) 减少 (Decrease)

چالش

Try to find a news headline today involving a number going down. Replace '减少' with '锐减' and see if it fits the dramatic tone of the story.

ریشه کلمه

The word 锐减 is a modern compound. '锐' (ruì) appears in ancient texts meaning 'sharp' or 'pointed,' often referring to weapons or elite soldiers. '减' (jiǎn) is a common verb for subtraction dating back to the Han dynasty. The combination to describe statistical drops became prevalent in the 20th century with the rise of modern journalism and economics.

معنای اصلی: A 'sharp subtraction' or 'cutting decrease.'

Sino-Tibetan (Mandarin Chinese).

بافت فرهنگی

No specific sensitivities, but using it for a person's weight loss might be seen as overly clinical or implying they are sick, rather than 'slimming down' (减肥).

The closest English equivalent is 'to plummet,' 'to nosedive,' or 'to drop sharply.' However, 锐减 is slightly more formal and clinical than 'nosedive.'

Used in CCTV's 'News 30' to describe international oil price drops. Commonly found in the 'China Statistical Yearbook' (中国统计年鉴). Used in environmental documentaries like 'Beautiful China' (美丽中国).

سوالات متداول

10 سوال

Technically yes, but it sounds very clinical or dramatic, like you lost 10kg in a week due to illness. For normal weight loss, use '瘦了' or '减肥成功.' If you use 锐减, it sounds like a medical report.

It is intransitive. You should say 'The population 锐减-ed,' not 'The war 锐减-ed the population.' For the latter, use '导致人口锐减' (caused the population to decrease sharply).

They are nearly synonyms. 锐减 emphasizes the 'sharp' (锐) nature of the decline, while 骤减 emphasizes the 'sudden' (骤) timing. In most business contexts, 锐减 is slightly more common.

Usually, 锐减 is used for negative things like profits, population, or resources. If something bad decreases, like 'crime rates,' we usually use '大幅下降' or '骤降.' 锐减 has a slightly 'alarming' tone.

Yes, it is typically associated with HSK 5 or HSK 6. It is a frequent flyer in the reading and listening sections of higher-level exams.

You say '锐减了百分之五十' (ruìjiǎn le bǎifēnzhī wǔshí).

No, that sounds ungrammatical. Use '锐减了许多' or just '锐减' because the 'many' part is already implied by the word itself.

The most common antonym is '激增' (jīzēng - to increase sharply) or '锐增' (ruìzēng - to increase sharply).

Only if you are being dramatic or writing a technical review of the battery's performance. In daily life, '掉电快' is more natural.

Rarely. It is too clinical and modern for traditional poetry. It is a word of the 'data age.'
