Erklärung 延长 in your Level:

At the A1 level, you might not use '延长' (yáncháng) yourself, but you might hear it in very simple contexts. Think of it as 'making something more long.' For example, if a teacher says a class will be '延长' for 5 minutes, they are adding time. You can remember it by the character '长' (cháng), which you already know means 'long.' It's like saying 'plus long.' At this stage, focus on the idea that it's about adding time to something that is already happening. Don't worry about complex grammar; just recognize that '延长' + '时间' (time) means 'more time.'

At the A2 level, you can start using '延长' in basic sentences about your daily life. You might use it to talk about staying somewhere longer than planned. For example, '我想延长我的假期' (I want to extend my vacation). You will see this word in signs at shops, like '延长营业时间' (extended business hours). This is a great word to use when you need more of something that has a limit. Remember the pattern: [Thing] + 延长了 + [Amount of time]. For example, '电影延长了十分钟' (The movie was extended by 10 minutes).

At the B1 level, '延长' is a key vocabulary word, especially for exams like the HSK 4 or IELTS. You should be able to use it in formal letters and professional settings. You need to distinguish between '延长' (extending duration) and '延期' (postponing a deadline). For example, if you are writing to a professor to ask for more time on an essay, you are asking to '延长截止日期' (extend the deadline). You should also understand that '延长' can be used for physical things, like '延长这条路' (extend this road). Your goal at B1 is to use it accurately in the 'Verb + Object' and 'Verb + Duration' patterns.

At the B2 level, you should be comfortable using '延长' in abstract and complex contexts. You might discuss social issues like '延长退休年龄' (extending the retirement age) or scientific topics like '延长细胞寿命' (extending cell lifespan). You should be able to use resultative complements like '延长到...' (extend to...) or '延长至...' (extend until...) fluently. You should also be aware of its synonyms like '延续' or '展延' and know when to choose '延长' for its specific focus on lengthening rather than just continuing. Your sentences should look more like: '政府正考虑通过政策手段来延长经济增长的周期。'

At the C1 level, you use '延长' with precision and stylistic flair. You might use it in legal or academic writing to describe the 'extension of a contract' (合同的延长) or the 'extension of a concept' to a new field. You understand the subtle difference between '延长' and '延展' (extending/expanding into a wider scope). You can use it in passive structures or complex noun phrases effortlessly. You are also aware of the word's role in classical-sounding four-character phrases or formal reports. At this level, you are not just using the word; you are choosing it specifically for its formal, objective tone.

At the C2 level, you have a complete command of '延长' and its place in the broader Chinese lexicon. you can use it metaphorically or in highly specialized fields like philosophy or advanced physics. You might use it to discuss the 'extension of human consciousness' or in high-level diplomatic discourse. You can manipulate the word within various registers, from the highly colloquial '拉长' to the extremely formal '展延' or '延宕'. You understand the historical etymology of the characters and can appreciate how the word has evolved in modern bureaucratic and technical Chinese.

延长 in 30 Sekunden

延长 (yáncháng) means to extend or lengthen in terms of time (deadlines, life) or space (roads, lines).
It is a formal, neutral verb commonly used in business, administration, and daily schedules.
Unlike '延期' (postpone), '延长' focuses on the duration or the length itself being increased.
Commonly paired with words like 寿命 (lifespan), 期限 (deadline), and 时间 (time).

The Chinese verb 延长 (yáncháng) is a versatile and essential term for any learner reaching the B1 level. At its heart, it signifies the act of making something longer. This 'lengthening' can occur in two distinct dimensions: space and time. Whether you are talking about extending a physical road or prolonging a meeting, 延长 is your go-to word. In modern life, you will most frequently encounter it in administrative contexts, such as extending a visa, prolonging a contract, or pushing back a deadline for a project. It carries a neutral to formal tone, making it perfect for both professional emails and news reports.

Temporal Extension (Time): This is the most common usage. It refers to lengthening the duration of an event, a period, or a deadline. For example, '延长寿命' (extending lifespan) or '延长营业时间' (extending business hours). It implies that the original end point has been moved further into the future.
Spatial Extension (Space): In a physical sense, 延长 describes making an object longer in length. If a city decides to '延长地铁线' (extend the subway line), they are physically adding more tracks and stations. It suggests a linear growth from an existing starting point.

由于天气原因，我们的假期将延长两天。
(Due to weather reasons, our vacation will be extended by two days.)

Understanding the nuance of 延长 requires looking at its components. The first character, 延 (yán), conveys the idea of stretching out or delaying. The second character, 长 (cháng), simply means long. When combined, they literally mean 'to make long by stretching.' This is why the word is so frequently used for things that have a defined 'length'—be it a length of time on a clock or a length of meters on a map. In the context of IELTS or other proficiency exams, 延长 is often the 'academic' version of simpler words like '增加' (add) or '多' (more) when talking about time limits.

这条公路将被延长到市中心。
(This highway will be extended to the city center.)

Common Objects of 延长: 1. 寿命 (lifespan) - 延长人类的寿命。
2. 期限 (deadline/period) - 延长签证的期限。
3. 时间 (time) - 延长会议的时间。
4. 距离 (distance) - 延长跑道的距离。

In summary, use 延长 whenever you want to express that a process, a period, or a physical line is getting longer than originally planned or existing. It is a word that suggests progression and continuation. It is rarely used for negative 'dragging' of time (where you might use 拖延), but rather for the objective lengthening of a duration or physical span.

Using 延长 (yáncháng) correctly in a sentence involves understanding its role as a transitive verb. It typically follows the structure: Subject + 延长 + Object. However, it often appears with resultative complements or duration markers to specify exactly how much longer something has become. Let's break down the grammatical patterns that will make your Chinese sound natural and sophisticated.

Pattern 1: Direct Object: The simplest way is to follow the verb with the thing being extended.
Example: '超市延长了营业时间。' (The supermarket extended its business hours.) Here, '营业时间' is the direct object.
Pattern 2: Expressing the Amount (延长 + Duration/Length): When you want to say 'extended BY a certain amount,' place the duration or length immediately after the verb.
Example: '会议延长了半个小时。' (The meeting was extended [by] half an hour.) Note that Chinese does not require a word for 'by' in this structure.

医生建议通过运动来延长寿命。
(Doctors suggest exercising to extend one's lifespan.)

Another important structure involves the use of 到 (dào) to indicate the new end point. The pattern is 延长到 + [New Time/Location]. This is extremely common when discussing dates. For instance, if a deadline was originally Monday but is now Wednesday, you would say '截止日期延长到了周三' (The deadline has been extended to Wednesday). This is much more precise than just saying it was extended.

我们正在申请延长签证的有效期。
(We are applying to extend the validity of the visa.)

Pattern 3: With '至' (Formal): In very formal or academic contexts, '到' is often replaced by '至' (zhì).
Example: '工期延长至明年六月。' (The construction period is extended until June next year.)

When using 延长 for physical space, it often pairs with directional verbs. For example, '向北延长' (extend toward the north). This helps the listener visualize the direction of the growth. Remember that 延长 is a positive or neutral action; it implies adding value or necessity. If you are 'extending' something because of laziness or procrastination, you should switch to 拖延 (tuōyán), which has a negative connotation of 'stalling.'

The word 延长 (yáncháng) is ubiquitous in Chinese-speaking environments, appearing in settings ranging from government offices to shopping malls. Understanding the specific scenarios where it pops up will help you recognize it instantly. It is a 'high-yield' word because it bridges the gap between daily conversation and professional jargon.

1. At the Immigration Office (EE/Visa): If you are an expat in China, this is the word you will hear most often. '延长签证' (Extend a visa) or '延长居留许可' (Extend a residence permit) are standard phrases. You will see this on forms and hear it from officers discussing your stay duration.
2. In Public Transport Announcements: During holidays like Chinese New Year or Mid-Autumn Festival, subways in cities like Beijing or Shanghai often run later. You will hear announcements like: '为了方便乘客，今晚地铁一号线将延长运营时间一小时。' (To facilitate passengers, Subway Line 1 will extend its operating time by one hour tonight.)

政府决定延长退休年龄。
(The government has decided to extend the retirement age.)

In the corporate world, 延长 is the standard term for project management. When a deadline cannot be met, the manager might say '延长截止日期' (extend the deadline). In business contracts, you might see a clause about '延长合同' (extending the contract). It sounds much more professional than saying '继续' (continue) or '再给点时间' (give a bit more time).

因为下雨，网球比赛不得不延长。
(Because of the rain, the tennis match had to be extended.)

Finally, you will hear it in the context of urban development. China is famous for its rapid infrastructure growth. News reports frequently mention '延长道路' (extending roads) or '延长铁路线' (extending railway lines). In these cases, the word represents progress and the physical expansion of a city's reach. Whether you are reading a newspaper or listening to a radio broadcast, 延长 is a marker of things growing, lasting longer, or reaching further.

While 延长 (yáncháng) seems straightforward, English speakers often stumble over its specific usage boundaries. The most common errors involve confusing it with other 'time' or 'length' related verbs, or using the wrong grammatical structure when specifying the amount of extension.

Mistake 1: Confusing 延长 (yáncháng) with 延期 (yánqī): This is the #1 mistake. 延长 refers to the duration (how long a period is), while 延期 refers to the start time or a specific point in time (postponing).
Incorrect: '把会议延长到明天。' (This sounds like the meeting will last from now until tomorrow).
Correct: '把会议延期到明天。' (Postpone the meeting to tomorrow).
Mistake 2: Using '延长' for Negative Stalling: If someone is being lazy and putting off work, do not use 延长. Use 拖延 (tuōyán). 延长 is usually an objective or positive extension of a limit.
Incorrect: '他在延长做作业。' (He is extending doing homework—sounds weird).
Correct: '他在拖延做作业。' (He is procrastinating on his homework).

❌ 延长我学习的时间。
✅ 延长我的学习时间。
(Grammar note: Keep the verb and object close; possessives like '我的' should modify the whole object.)

Another common error is the placement of the duration. In English, we say 'extend for two hours.' In Chinese, you do NOT need a preposition like '为' or '给'. Just put the time right after the verb. Saying '延长为两个小时' is a common 'Chinglish' error that sounds unnatural.

这条路延长了五公里。
(This road was extended [by] five kilometers. Don't add extra words!)

Lastly, remember that 延长 is a verb. Beginners sometimes try to use it as an adjective or a noun without the proper support. For example, '这是一个延长的假期' (This is an extended holiday) is okay, but it's more common to say '假期延长了' (The holiday was extended). Always check if you are describing the action of lengthening or the result of being long.

To truly master 延长 (yáncháng), you must see how it fits into the family of Chinese words that deal with time and extension. Choosing the right synonym can make the difference between a 'good' and a 'native-like' sentence. Here is a comparison with its closest relatives.

延长 (yáncháng) vs. 延期 (yánqī): 延长: To lengthen a duration (e.g., '延长生命' - make life longer).
延期: To postpone a date (e.g., '会议延期了' - the meeting is moved to a later date).
Example: If a 1-hour meeting becomes 2 hours, it is 延长. If a 2 PM meeting becomes a 4 PM meeting, it is 延期.
延长 (yáncháng) vs. 延续 (yánxù): 延长: Focuses on the added length.
延续: Focuses on the unbroken flow or continuation of a state/tradition.
Example: '这种风格延续了三百年' (This style has continued for 300 years).

我们决定延长优惠活动的期限。
(We decided to extend the duration of the promotion.)

There are also more specific alternatives depending on the context:

伸长 (shēncháng): To physically stretch something out (like a neck or an elastic band). '伸长脖子' (Stretching one's neck).
展延 (zhǎnyán): A more formal/legal term for 'extension,' often used in banking or high-level administration.
拉长 (lācháng): Literally 'pull long.' Used for physical stretching or colloquially for making a process take longer than it should.

When in doubt, 延长 is the safest choice for most 'extension' scenarios. It is formal enough for business but common enough for daily life. Just remember the 'Space vs. Time' rule, and you will use it correctly 99% of the time.

How Formal Is It?

Wusstest du?

The character '长' is one of the most famous 'polyphonic' characters in Chinese. When pronounced 'cháng', it means 'long'. When pronounced 'zhǎng', it means 'to grow' or 'elder'. In 延长, it preserves its original meaning of physical length.

Herausforderung

Try to use '延长' in three different contexts today: one about time (like a meeting), one about a document (like a visa), and one physical object (like a string).

Wortherkunft
