A2 preposition #600 最常用 11分钟阅读

در طول

dar tool 前600

At the A1 level, you are just starting to learn how to describe your day. 'در طول' (dar tul-e) might seem a bit long, but you can think of it as a way to say 'during'. If you want to say you do something 'during the day' or 'during the night', this is the phrase to use. It's like a bridge that connects your action to a time. Just remember to say the 'e' sound at the end of 'tul'. For example, 'dar tul-e ruz' (throughout the day). It helps you move from saying simple things like 'I eat' to more detailed things like 'I eat throughout the day'. Don't worry about the spelling too much yet; just focus on the sound and the idea of a 'long' time.

At the A2 level, you can start using 'در طول' to describe your hobbies, trips, and routines more accurately. Instead of just saying 'in the summer', you can say 'throughout the summer' to show that you did something many times or for a long time. It's very useful for talking about your past experiences. For example, 'Throughout the trip, we were happy.' This shows you are starting to understand how to link ideas together. You should also notice that 'tul' means 'length', so you are literally saying 'in the length of'. This will help you remember that it's for periods of time, not just one specific hour.

As a B1 learner, you should be comfortable using 'در طول' in both speaking and writing. You can now use it with more abstract nouns like 'the process', 'the meeting', or 'the conversation'. It helps you provide better context in your stories. You should also start comparing it with other words like 'dar heyn-e' (during/while). 'در طول' is for the whole duration, while 'dar heyn-e' is for something happening at the same time as something else. For example, 'Throughout the movie (dar tul-e film), I was thinking about my work.' This level of detail makes your Persian sound much more natural and intermediate.

At the B2 level, 'در طول' becomes a tool for more formal and academic expression. You will see it in news articles, reports, and literature. You should be able to use it to describe trends over time, such as 'throughout the last decade' or 'throughout the history of Iran'. You should also be aware of its formal synonyms like 'dar tay-ye'. At this stage, you should use 'در طول' to create complex sentences that show cause and effect over a period. For example, 'Throughout the negotiations, many problems were solved.' This shows you can handle professional topics with ease.

For C1 learners, 'در طول' is a basic tool that you use with precision. You understand the subtle difference between 'dar tul-e' and 'sartasar-e' (all throughout). You can use it in high-level discussions about philosophy, history, or science. You might use it to describe the evolution of a concept 'throughout the works of a specific poet'. You are also sensitive to the rhythm of the sentence, knowing when 'dar tul-e' provides the right flow compared to more concise options. Your usage is now indistinguishable from a native speaker's in terms of placement and context.

At the C2 level, you have mastered the nuances of 'در طول' and can even use it in creative or poetic ways. You might use it to play with the spatial metaphor of 'length' in time. You are fully aware of its historical development and how it functions in different dialects of Persian (like Dari or Tajik). You can use it in extremely formal legal or diplomatic documents where every word counts. You also know when to omit the 'dar' in very specific poetic contexts while maintaining the meaning. Your command of this phrase is absolute, allowing for both clarity and stylistic flair.

A versatile prepositional phrase meaning 'throughout' or 'during the course of' a specific time period.
Formed by combining 'dar' (in) and 'tul' (length), using a spatial metaphor to describe temporal duration.
Essential for formal writing, news reporting, and daily conversations about routines and experiences.
Requires the 'ezafe' (short 'e' sound) to connect to the noun that defines the time span.

The Persian prepositional phrase در طول (dar tul-e) is a fundamental building block for expressing duration and temporal continuity in the Persian language. At its core, it translates to "throughout," "during," or "over the course of." To understand its usage, one must look at its constituent parts: dar meaning "in" and tul meaning "length." Literally, you are saying "in the length of" a specific time period. This spatial metaphor for time is common in many languages, but in Persian, it carries a specific weight of continuity, suggesting that an action or state persists from the beginning to the end of a timeframe.

Temporal Span: It is most frequently used with time-bound nouns such as 'day', 'year', 'history', or 'journey'. It implies that something is happening consistently or repeatedly within that window.
Formal vs. Informal: While highly common in formal writing and news broadcasts, it is also used in daily speech, though sometimes shortened to just 'tul-e' in very casual contexts.
Logical Flow: It functions as a linker, setting the stage for the main action by defining the temporal boundaries within which the action occurs.

ما در طول سفر کتاب‌های زیادی خواندیم.
— We read many books throughout the trip.

In Persian culture, where storytelling and historical narrative are deeply valued, در طول serves as a vital tool for historians and poets alike. It allows for the description of sweeping changes over centuries or the subtle shift of emotions over a single evening. When you use this phrase, you are inviting the listener to look at the entire 'length' of the event, rather than just a single point in time. This distinction is crucial; unlike 'dar' (in) which might indicate a specific moment, در طول emphasizes the journey and the process.

او در طول روز ورزش می‌کند.
— He exercises throughout the day.

Furthermore, the phrase is indispensable in academic and professional settings. Whether discussing economic trends "throughout the fiscal year" or biological processes "throughout the life cycle," در طول provides the necessary precision. It is a versatile tool that bridges the gap between the poetic and the practical, making it one of the first compound prepositions a learner should master to move beyond basic sentence structures.

تکنولوژی در طول ده سال گذشته تغییر کرده است.
— Technology has changed throughout the last ten years.

Historical Context: In classical Persian literature, you might find variations, but the modern 'dar tul-e' has become the standard for temporal duration in contemporary Iranian Persian (Farsi), Dari, and Tajik.

Using در طول correctly requires an understanding of the Persian 'Ezafe' construction. Since در طول acts as a prepositional phrase, it must be linked to the noun that follows it using the short 'e' sound. This is the grammatical glue of the Persian language. When you say "throughout the week," you say dar tul-e hafte. Without that 'e' sound, the sentence falls apart. This section will guide you through the various ways to integrate this phrase into your speech and writing, from simple daily activities to complex historical analysis.

Placement: Typically, the phrase 'dar tul-e [Time Period]' appears at the beginning of a sentence to set the context, or immediately after the subject. For example: 'In the length of the night, I was awake' or 'I, in the length of the night, was awake.'
Compatibility: It works best with nouns that represent a span of time. You wouldn't use it with a single point in time like '3 o'clock'. Instead, use it with 'the meeting', 'the class', 'the winter', or 'the century'.

در طول زمستان، کوه‌ها پوشیده از برف هستند.
— Throughout the winter, the mountains are covered in snow.

One of the most powerful aspects of در طول is its ability to emphasize the repetitive or continuous nature of an action. If you say "I studied in the night," it might mean you studied for ten minutes. But if you say "I studied در طول the night," it implies a dedicated, ongoing effort that spanned the entire duration of the darkness. This nuance is what allows Persian speakers to convey depth and commitment in their descriptions.

گیاهان در طول شب رشد می‌کنند.
— Plants grow throughout the night.

When constructing more complex sentences, you can pair در طول with adjectives. For instance, "throughout the long journey" becomes dar tul-e safar-e tulani. Notice how the word 'tul' (length) and 'tulani' (long) share the same root, creating a rhythmic and poetic quality in the sentence. This root-sharing is a hallmark of Persian eloquence.

او در طول زندگی‌اش کارهای بزرگی انجام داد.
— Throughout his life, he performed great deeds.

Negative Sentences: In negative sentences, it emphasizes that an action did NOT happen at any point during the duration. 'He didn't speak throughout the meeting' implies total silence from start to finish.

Finally, consider the emotional weight. Using در طول in a sentence about a difficult time, like "throughout the illness," shows a sense of endurance. It acknowledges the passage of time as a physical distance that had to be traveled. This is why you will often hear it in memoirs and personal stories, as it helps the narrator map out their experiences across the timeline of their life.

If you turn on an Iranian news channel like IRINN or listen to a BBC Persian broadcast, you will hear در طول within the first five minutes. It is the preferred phrase for journalists reporting on events that have unfolded over time. Whether it's "throughout the last week's protests" or "throughout the negotiations in Geneva," it provides a professional and clear temporal framework. It is the language of record, used to anchor events in a specific span of time.

The Newsroom: Anchors use it to summarize long-term trends. 'Throughout the year, inflation has risen' is a classic example of the phrase in a financial report.
Documentaries: In nature or history documentaries, the narrator will use it to describe processes: 'Throughout the Jurassic period...' or 'Throughout the migration of the birds...'

گزارش‌ها در طول هفته منتشر خواهند شد.
— Reports will be published throughout the week.

In the classroom, teachers use در طول to set expectations for their students. A teacher might say, "Throughout this semester, we will study Persian poetry." Here, the phrase acts as a roadmap, defining the scope of the educational journey. It is also found in textbooks, especially in history and science, where the concept of duration is central to the subject matter. Students learn early on that this phrase is a signal for important contextual information.

لطفاً در طول امتحان صحبت نکنید.
— Please do not talk throughout the exam.

In everyday Iranian life, you'll hear it in conversations about health and routine. A doctor might ask, "Have you had pain throughout the day?" or a mother might tell her child, "Make sure you drink water throughout the afternoon." In these contexts, it's less about formal reporting and more about the practicalities of managing one's time and well-being. It's a phrase that exists comfortably in both the high-brow literary world and the kitchen table conversation.

او در طول فیلم خوابش برد.
— He fell asleep throughout the movie.

Lastly, in the realm of cinema and television, در طول is used in scripts to indicate the passage of time or the development of a character's arc. A director might describe a character's change in temperament "throughout the story." It's a tool for narrative structure, helping creators and audiences alike understand how time shapes the world of the film.

One of the most frequent errors for English speakers learning Persian is confusing در طول with the simple preposition در (dar). While both can often be translated as "in" or "during," they are not interchangeable. Using 'dar' implies a point in time, whereas 'dar tul-e' implies the entire span. For example, saying 'dar hafte' (in the week) is grammatically acceptable but vague, while 'dar tul-e hafte' (throughout the week) specifically indicates the duration. Beginners often default to the simpler 'dar', missing the nuance of continuity.

The Missing Ezafe: The most common grammatical mistake is forgetting the 'ezafe' (the linking 'e' sound). Saying 'dar tul hafte' instead of 'dar tul-e hafte' sounds jarring and incomplete to a native speaker. It's like saying 'during week' instead of 'during the week' in English.
Confusing with 'Hengam': Another mistake is using 'dar tul-e' when 'hengam-e' (at the time of) is more appropriate. 'Hengam-e' is for specific events (like 'at the time of the accident'), while 'dar tul-e' is for extended periods (like 'throughout the recovery').

Mistake: من در طول ساعت سه آمدم.
Correct: من در ساعت سه آمدم.
— Explanation: You cannot use 'throughout' for a specific point in time like 3:00 PM.

Another subtle mistake involves the word order. In English, we can say "throughout the whole day," but in Persian, the adjective 'tamam' (whole) usually comes after the noun. So it would be dar tul-e tamam-e ruz or dar tul-e ruz-e kamel. Learners often try to translate the English word order directly, leading to awkward constructions like 'dar tamam-e tul-e ruz', which is redundant and clunky.

Mistake: او در طول ناهار خورد.
Correct: او در حین ناهار خوردن صحبت کرد.
— Explanation: 'Dar tul-e' is rarely used for short, specific activities like eating lunch unless you are emphasizing how long the lunch took.

Finally, be careful with the plural. While you can say "throughout the years" (dar tul-e sal-ha), learners sometimes forget to pluralize the noun, making the sentence sound like it's referring to a single year. Precision in number is just as important as precision in time when using this phrase. Always double-check if the duration you are describing is a single unit or a series of units.

While در طول is a versatile and common choice, Persian offers several other ways to express duration, each with its own specific flavor and register. Knowing these alternatives will help you sound more like a native speaker and allow you to choose the exact right word for the context. Whether you want to sound more formal, more poetic, or more concise, there is a synonym for every occasion.

در طی (Dar Tay-ye): This is perhaps the closest synonym. It is slightly more formal and is often used in administrative or literary contexts. It also means 'throughout' or 'during the course of'.
در حین (Dar Heyn-e): This specifically means 'in the middle of' or 'while'. It is used for actions that happen simultaneously with another action, often for shorter durations than 'dar tul-e'.
در جریان (Dar Jaryan-e): Literally 'in the flow of'. This is used for processes, meetings, or events that are ongoing. It carries a sense of movement and development.

در طی مراسم، هیچ‌کس صحبت نکرد.
— Throughout the ceremony, no one spoke. (Formal alternative)

For very long durations, such as historical eras, you might encounter در ادوار (dar advar-e), meaning "throughout the ages." This is a highly literary and grand way to describe time. On the other end of the spectrum, in very casual speech, people might just use توی (tuye), which is the informal version of 'dar'. However, 'tuye tul-e' is rarely said; instead, people usually just say 'tuye' + the time period, sacrificing the specific 'throughout' meaning for brevity.

در جریان مذاکرات، توافق حاصل شد.
— During the course of the negotiations, an agreement was reached.

Another interesting alternative is سرتاسر (sartasar), which means "all over" or "throughout" in a more emphatic sense. It can be used for both space and time. Saying sartasar-e ruz (all throughout the day) is more intense than dar tul-e ruz. It implies that there was not a single moment of the day that wasn't filled with the action being described. Use this when you want to emphasize the totalizing nature of an experience.

در مدت (Dar Moddat-e): Focuses on the 'period' or 'duration'. 'In the period of two years' would be 'dar moddat-e do sal'. It is more clinical and precise than the more general 'dar tul-e'.

Very High. It is one of the top 500 most used phrases in Persian.

常见错误

در طول ساعت پنج → در ساعت پنج
You cannot use 'throughout' for a specific point in time like 5:00.
در طول سفر خوش گذشت (without ezafe) → در طولِ سفر خوش گذشت
The linking 'e' sound is required between 'tul' and 'safar'.
به طول روز → در طول روز
'Be tul-e' is for physical length, 'Dar tul-e' is for time.
در طول ناهار (when meaning 'while eating') → در حین ناهار
'Dar tul-e' is for the whole duration, 'Dar heyn-e' is better for 'while' an action is happening.
در طول تمام روز (word order) → در طولِ تمامِ روز
While 'tamam' can come before, the ezafe must link every word in the chain.

小贴士

Remember the Ezafe

Always pronounce the 'e' at the end of 'tul'. It's the most important part for sounding natural.

Spatial Metaphor

Remember that 'tul' means length. You are literally talking about the 'length' of time.

Pacing

Use 'در طول' as a filler phrase to give yourself time to think about the rest of your sentence.

Formal Writing

In formal essays, try swapping 'در طول' with 'در طی' to sound more academic.

News Context

When you hear 'dar tul-e' on the news, get ready for a summary of events over time.

Historical Context

Iranians love history. 'در طول تاریخ' is a very common and respected way to start a point.

Duration vs. Point

Only use it for spans of time (weeks, years), not specific points (3 PM).

The Tool Ruler

Visualize a 'Tool' (tul) that is a ruler measuring time.

Don't say 'Be Tul-e'

Avoid 'be tul-e' for time; that's only for physical measurements like meters.

Emphasis

Add 'تمام' (tamam) after 'tul-e' to emphasize that something happened 'all' throughout.

记住它

记忆技巧

Think of a 'Tool' (tul) that measures the 'Length' of a day. You are 'In' (dar) that length.

挑战

Try to use 'در طول' three times today: once for something you did during the day, once for a movie or book, and once for a long-term goal.

词源

The phrase is a compound of the Persian preposition 'dar' and the Arabic loanword 'tul'. 'Dar' comes from Middle Persian 'dar', while 'tul' (طول) is the Arabic word for length. This combination is a classic example of Persian linguistic synthesis.

原始含义： In the length of.

Indo-European (Persian) + Afro-Asiatic (Arabic).

文化背景

No specific sensitivities. It is a neutral, widely used grammatical phrase.

English speakers often use 'during' for everything. Persian speakers prefer 'dar tul-e' when they want to emphasize the whole duration.

Used frequently in the 'Shahnameh' (Book of Kings) in modern prose translations to describe long reigns. Common in the lyrics of Googoosh and other pop icons to describe long-lasting love. A staple phrase in the speeches of Iranian political figures throughout the 20th and 21st centuries.
