解析 重度な in your Level:

At the A1 level, you don't need to use '重度な' (jūdo-na) yet. Instead, you would use simple words like 'とても' (very) and '悪い' (bad) or 'ひどい' (terrible). For example, instead of saying 'He has a severe illness,' an A1 student would say '彼はとても重い病気です' (He has a very heavy/serious illness). '重度な' is a formal word that you will see in newspapers or hear in hospitals. It is made of two parts: '重' (heavy) and '度' (degree). Even if you don't use it, knowing that '重' means something serious is very helpful for reading signs in Japan. At this stage, just remember that if you see this word, the situation is not good and is very serious.

At the A2 level, you are beginning to learn more specific adjectives. You might know '重い' (omoi) for 'heavy' or 'serious.' '重度な' (jūdo-na) is the more formal, 'na-adjective' version of this. You will start to see it in simple news articles or health-related materials. It is important to understand that '重度な' is used for things like health problems. You shouldn't use it for things like 'heavy bags' or 'heavy rain.' For those, you still use '重い' or '強い.' When you see '重度な' in a sentence, think of it as 'Level: High' or 'Level: Severe.' It is a step up from 'ひどい' (terrible) and sounds more like a professional diagnosis.

As a B1 learner, '重度な' (jūdo-na) is a key vocabulary word for discussing health, social issues, and disabilities. At this level, you are expected to move beyond general adjectives like 'ひどい' and use more precise terms. '重度な' is specifically used to describe the 'degree' (度) of a condition. You will often find it in the context of '重度な障害' (severe disability) or '重度な依存症' (severe addiction). You should also learn its opposite, '軽度な' (keido-na), which means 'mild' or 'light degree.' Using these words correctly shows that you can handle formal situations and understand the nuances of Japanese classification systems. You will likely hear this word in documentaries or read it in social welfare articles.

At the B2 level, you should be comfortable using '重度な' (jūdo-na) and understand its grammatical nuances, such as when to use '重度な' versus '重度の.' You will also need to distinguish it from similar words like '深刻な' (shinkoku-na - serious/grave) and '甚大な' (jindai-na - enormous). While '深刻な' is used for abstract societal problems, '重度な' is reserved for quantifiable medical or functional states. You might encounter this word in academic texts, legal documents regarding healthcare, or detailed medical reports. A B2 learner should be able to explain the severity of a situation using this word in a professional setting, such as a workplace or a clinic.

For C1 learners, '重度な' (jūdo-na) is part of a broader set of technical vocabulary. You should understand the specific legal and medical implications of this word in Japan, such as how '重度' classification affects government subsidies and support for the elderly or disabled. You should be able to use it in complex sentence structures and understand its role in formal writing (kango). At this level, you might also explore related terms like '最重度' (sai-jūdo - most severe) or '重複重度' (chūfuku jūdo - multiple severe disabilities). Your understanding should include the subtle shift in tone when a writer chooses '重度な' over '重度の,' often to emphasize the state as a descriptive quality rather than just a category.

免费注册阅读完整解释

At the C2 level, '重度な' (jūdo-na) is a word you use with total precision within specialized fields like medicine, psychology, or sociology. You understand the historical evolution of how 'severity' has been classified in Japanese policy. You can discern the nuances between '重度な,' '深刻な,' '重篤な' (jūtoku-na - critically ill), and '甚大な.' You are capable of reading high-level medical journals or legislative texts where '重度' is defined by specific criteria and metrics. Your usage reflects a deep understanding of the register, ensuring that you never use it in a context where a more nuanced or less clinical term is required. You can also discuss the social stigma or policy challenges associated with conditions classified as '重度' in Japanese society.

重度な 30秒了解

Formal adjective for 'severe' or 'serious' conditions.
Used mainly for medical, physical, or psychological states.
Composed of kanji for 'heavy' and 'degree'.
Essential for understanding Japanese social welfare and health news.

The Japanese word 重度な (jūdo-na) is a powerful adjective used to describe conditions, symptoms, or states that have reached a high level of severity or seriousness. Etymologically, it is composed of two kanji: 重 (jū) meaning 'heavy' or 'serious' and 度 (do) meaning 'degree' or 'extent.' When combined, they literally translate to 'a heavy degree.' In a medical or social context, this word is not used lightly; it signifies that a situation is at the upper end of a scale, often requiring intensive care, intervention, or significant support.

Medical Context: Used to classify the stage of a disease or the extent of a disability. For example, '重度な障害' (jūdo-na shōgai) refers to a severe disability.

彼は重度なアレルギーを持っています。(He has a severe allergy.)

While 重度 (jūdo) is technically a noun, adding な (na) turns it into a 'na-adjective' used to modify nouns directly. However, in many formal medical documents, you might also see it as 重度の (jūdo no). The nuance of 重度な often feels slightly more descriptive of the state itself rather than just a classification. It is a B1 level word because while basic learners might use 'ひどい' (hidoi - terrible/bad), a B1 learner needs the specific terminology used in professional, clinical, or news-related discussions.

Social Impact: It often appears in discussions regarding social welfare and accessibility, specifically identifying individuals who need the most assistance.

政府は重度な介護が必要な人を支援しています。(The government supports people who need severe/intensive nursing care.)

In everyday conversation, you might hear it when discussing psychological states as well, such as '重度なストレス' (severe stress) or '重度なうつ病' (severe depression). It carries a weight that suggests the person is struggling significantly and that the condition is not just a passing phase. Understanding this word helps you navigate Japanese healthcare systems and understand news reports about public health crises or social issues.

Comparison: Compared to '深刻な' (shinkoku-na), which means 'serious' in a general or abstract sense (like a serious problem), '重度な' is more focused on the measurable degree of a physical or mental state.

Using 重度な (jūdo-na) requires understanding its placement as a na-adjective. It almost always precedes a noun to define the intensity of that noun. While it is grammatically simple to use, the choice of the noun it modifies is crucial for natural-sounding Japanese. It is most commonly paired with words related to health, psychology, and physical conditions.

Structure 1: [Noun] + は + [重度な] + [Noun] + です: Used to define a subject's condition. '彼の症状は重度な感染症です' (His symptoms are a severe infection).

重度な火傷を負ったため、すぐに入院しました。(Because they suffered severe burns, they were hospitalized immediately.)

One common variation is the use of the particle の (no) instead of な (na). While '重度な障害' is correct, '重度の障害' is actually more frequent in medical reports. However, in modern, slightly more descriptive writing, 'な' is used to emphasize the 'adjectival' quality of the severity. You will also see it used with abstract concepts that can be quantified, like '依存' (dependence/addiction).

Structure 2: [重度な] + [Noun] + に + [Verb]: Used to describe an action taken due to a severe state. '重度な不眠に悩まされる' (To be troubled by severe insomnia).

その子は重度なアトピー性皮膚炎に苦しんでいます。(That child is suffering from severe atopic dermatitis.)

When using this word, be careful not to use it for positive things. You wouldn't say '重度な喜び' (severe joy). It is strictly for negative, pathological, or problematic states. It can also describe environmental or technical failures that have reached a critical 'degree,' though this is less common than biological usage.

Collocation: 重度な依存症: Often used for severe addiction (gaming, alcohol, drugs). '彼は重度なゲーム依存症だ' (He has a severe gaming addiction).

In summary, treat '重度な' as a formal, clinical way to say 'extremely serious' or 'severe' regarding health or functional states. It provides a level of precision that common adjectives like '大きい' (big) or '大変な' (difficult/serious) lack in a professional context.

You will encounter 重度な (jūdo-na) in specific domains of Japanese life. It is not a word usually heard at a casual dinner party unless the topic turns to health or social policy. Instead, it is a staple of professional and informational settings.

1. Hospitals and Clinics: Doctors use this to explain diagnoses to patients or families. '重度な貧血' (severe anemia) or '重度な肺炎' (severe pneumonia) are terms used in medical consultations.

「重度な脱水症状が見られるので、点滴が必要です。」(Since severe dehydration symptoms are seen, an IV drip is necessary.)

2. **News and Documentaries**: When reporting on public health issues, such as the spread of a virus or the aging population, news anchors use '重度な' to categorize the impact. You might hear about '重度な心身障害者' (persons with severe mental or physical disabilities) when discussing government budgets or social welfare laws.

2. Government and Administrative Offices: When applying for disability certificates (障害者手帳), the classifications are often divided into '軽度' (light), '中等度' (medium), and '重度' (severe).

彼は重度な知的障害と診断されました。(He was diagnosed with a severe intellectual disability.)

3. **Academic and Psychological Research**: In psychology papers or educational reports, '重度な' is used to describe the intensity of conditions like ADHD, autism, or learning disabilities. It helps researchers categorize subjects and results.

In summary, this word is the 'classification' word. It tells the listener that the situation has passed a certain threshold of seriousness. If you hear it, pay attention, as it usually precedes information about urgent care or significant life impacts.

While 重度な (jūdo-na) is a useful word, learners often misuse it in ways that sound unnatural to native speakers. Here are the most common pitfalls to avoid.

Mistake 1: Using it for 'Inconvenience': Learners might say '重度な雨' (severe rain). This is incorrect. For weather, use '激しい' (hageshii) or 'ひどい' (hidoi). '重度な' is for states of being, not weather events.

❌ 重度な雨で遅れました。
✅ 激しい雨で遅れました。

Mistake 2: Confusing it with **深刻な (shinkoku-na)**. While both mean 'serious,' *shinkoku-na* is for abstract problems (economic crisis, environmental issues), while *jūdo-na* is for the degree of a condition (illness, disability). You wouldn't say '重度な経済危機' (a severe economic crisis); you would say '深刻な経済危機'.

Mistake 2: Overusing the 'na' particle: As mentioned, '重度の' (jūdo no) is often more natural in technical contexts. If you always use '重度な', you might sound slightly like a textbook. Pay attention to how native speakers alternate between the two.

Natural: 重度のうつ病 (Severe depression).
Descriptive: 重度な症状 (Severe symptoms).

Mistake 3: Using it for positive intensity. You cannot have '重度な才能' (severe talent). Use '豊かな' (yutaka-na) or '優れた' (sugureta) instead. '重度な' always implies a burden or a pathology.

Finally, avoid using it to describe people directly without a following noun like '障害' or '症状'. Saying '彼は重度です' (He is severe) is vague and potentially rude. Always specify what is severe: '彼は重度な障害を持っています' (He has a severe disability).

To truly master 重度な (jūdo-na), you must understand where it sits among its synonyms. Japanese has many ways to say 'serious' or 'severe,' each with its own flavor.

1. 深刻な (Shinkoku-na): Meaning: Serious, grave. Used for abstract problems or situations that cause worry. '深刻な悩み' (Serious worries). Unlike '重度な', it doesn't refer to a physical degree but to the emotional or social weight of a problem.
2. 重い (Omoi): Meaning: Heavy, serious. This is the simple, everyday version of '重度な'. '病気が重い' (The illness is serious). It's used in daily conversation while '重度な' is more formal and clinical.
3. 激しい (Hageshii): Meaning: Intense, violent. Used for movement, weather, or pain. '激しい痛み' (Intense pain). '重度な' describes the *state* of the condition, whereas '激しい' describes the *sensation* or *activity*.

Comparison Chart:
• Medical Diagnosis: 重度な
• Social Issue: 深刻な
• Weather/Pain: 激しい
• Casual Health: 重い

4. **致命的な (Chimeiteki-na)**: Meaning: Fatal, lethal. This is much stronger than '重度な'. While '重度な' means severe, '致命的な' implies that it will lead to death or total failure. '致命的なミス' (A fatal mistake).

5. **甚大な (Jindai-na)**: Meaning: Enormous, immense. Usually used for damages or losses, often in the context of natural disasters. '甚大な被害' (Enormous damage). It is more formal and used for large-scale physical destruction.

Choosing the right word shows your mastery of Japanese register. Using '重度な' in a casual conversation about a headache might sound overly dramatic or clinical, whereas using 'ひどい' in a medical report would sound unprofessional.

小贴士

Medical Context

Always use '重度な' or '重度の' when discussing formal medical classifications like 'severe autism' or 'severe burns'.

Na vs No

If you are unsure, '重度の' is a safe bet for formal writing, but '重度な' is great for adding a descriptive feel to your speech.

Opposites

Memorize '軽度' (mild), '中等度' (moderate), and '重度' (severe) as a set to understand the scale of severity in Japanese.

Common Pairs

Learn it with '障害' (disability) and '依存症' (addiction) as these are the most frequent pairings.

Formal Situations

Use this word in business or medical meetings to sound more professional and precise than using 'ひどい'.

Kanji Practice

Practice writing 重 (heavy) and 度 (degree) together. The stroke order for 重 can be tricky, so pay attention to the middle part.

Avoid Exaggeration

Don't use '重度な' for small things like a paper cut. It makes you sound like you are overreacting.

News Keywords

When you hear 'jūdo' on the news, it's often followed by 'shōgaisha' (disabled person) or 'kanja' (patient).

Social Welfare

Understanding '重度' will help you understand how Japanese society classifies and supports people with high needs.

Judo Analogy

Remember: A 'Heavy' (Jū) 'Degree' (Do) of Judo is a severe situation!

记住它

记忆技巧

Think of 'Judo' (the sport) being 'Heavy' (Jū). If you get hit with a heavy degree of Judo, it's 'Jūdo-na' (severe).

视觉联想

Imagine a scale where the pointer is all the way to the right under a heavy weight labeled 'Jū'.

Be careful when using this to describe people; focus on the condition or the disability, not the person as a whole, to remain respectful.

In English, we might use 'severe' or 'profound' for disabilities. '重度な' maps closely to 'severe'.

Medical dramas like 'Doctor X' often use this word. Welfare laws like the 'Services and Supports for Persons with Disabilities Act'. News reports on the '8050 problem' (elderly parents caring for middle-aged children with severe needs).

Generally, no. For a headache, 'ひどい頭痛' (hidoi zutsū) or '激しい頭痛' (hageshii zutsū) is much more natural. '重度な' sounds like a clinical classification you'd see on a medical chart.

'重度な' is a na-adjective that emphasizes the descriptive quality of being severe. '重度の' uses the particle 'no' to link the noun 'severity' to another noun. '重度の' is slightly more common in formal medical writing, while '重度な' is often used in descriptive sentences.

No, '重度な' is strictly for negative or pathological states. You would never say '重度な幸せ' (severe happiness).

The opposite of '重度な' is '軽度な' (keido-na), meaning 'mild' or 'light degree.' For example, '軽度な風邪' (a mild cold).

No. For severe weather, use '激しい' (hageshii) for intensity or 'ひどい' (hidoi) for bad conditions. '重度な' is for states of being or conditions of objects.

Yes, but '重大なミス' (jūdai-na misu - serious mistake) is more common. '重度な' might be used if the mistake is viewed as a 'defect' in a system.

Yes, '重度' is a noun meaning 'severity.' You can say '重度が高い' (the severity is high), though it's less common than using it as an adjective.

It is considered B1. While the kanji are learned earlier, the specific clinical and formal usage is expected of intermediate learners.

It is a formal, neutral word. It is not 'polite' (keigo) in itself, but it is appropriate for professional and respectful contexts.

You should use it to modify a noun describing a person's condition, like '重度な障害のある人' (a person with a severe disability), rather than just saying 'a severe person'.
