عبارات مفعولی (مجهول): جملات خود را کوتاه کنید
Grammar Rule in 30 Seconds
Use past participles to replace 'which was' or 'because it was' for elegant, professional, and concise English writing.
- Drop the subject and 'be' verb: 'The book, which was written in 1920' becomes 'Written in 1920'.
- Ensure the subjects match: The person/thing doing the action in both clauses must be identical.
- Use for reasons or descriptions: 'Shocked by the news, she fainted' (Because she was shocked).
مرور کلی
Syntactic Compression یکی از نشانههای اصلی مهارت زبانی است. یکی از این ابزارهای قدرتمند، «عبارات اسم مفعول» یا Past Participle Clauses است. در زبان فارسی، ما برای بیان مفاهیم مشابه، معمولاً از جملات پیرو با «که» (جملات موصولی) یا عبارات وصفی ساده استفاده میکنیم.The letter, written by the manager, is on the desk.Past Participle به تنهایی میتواند معنای مجهول را در دل خود حمل کند. این کار باعث میشود جملات شما از حالت طولانی و تکراری خارج شده و به متون آکادمیک و حرفهای نزدیکتر شود. بسیاری از زبانآموزان فارسیزبان به دلیل عادت به ساختار فاعل-مفعول-فعل (SOV) در فارسی، تمایل دارند جملات را با ساختارهای کامل which was یا that were بنویسند.Past Participle Clause در واقع یک «جمله کاهشیافته» (Reduced Clause) است. در دستور زبان فارسی، ما مفهومی به نام «اسم مفعول» داریم (مانند: نوشتهشده، دیده شده، ساختهشده). تفاوت اینجاست که در فارسی، اسم مفعول معمولاً به عنوان صفت پیش از اسم یا در ترکیب با فعل کمکی «شدن» میآید.Past Participle (شکل سوم فعل یا V3) میتواند به تنهایی نقش یک فعل مجهول را در یک عبارت ایفا کند.- 1جملات موصولی مجهول (
Passive Relative Clauses): وقتی میگوییمThe book which was written by him، در واقعwhich wasزاید است و میتوان آن را حذف کرد تا بهThe book, written by himبرسیم. - 2جملات قیدی (
Adverbial Clauses): وقتی میگوییمBecause he was exhausted, he slept، میتوانیم آن را بهExhausted, he sleptتبدیل کنیم.
Exhausted, I slept. اگر فاعلها متفاوت باشند، این ساختار غیرممکن است.be و ضمیر موصولی را حذف کرده و فقط Past Participle (V3) را نگه دارید.The cake, baked by my mother, was delicious. | کیکی که توسط مادرم پخته شده بود، خوشمزه بود. |Seen from above, the city looks beautiful. | وقتی از بالا دیده میشود، شهر زیبا به نظر میرسد. |- 1متون آکادمیک و گزارشهای اداری: در محیطهای کاری یا دانشگاهی، جملات طولانی با
which wasیاthat wereخستهکننده هستند. استفاده ازPast Participleبه متن شما وقار و ایجاز میبخشد. - 2توصیف دقیق: وقتی میخواهید جزئیاتی را درباره یک اسم اضافه کنید بدون اینکه جمله اصلی را قطع کنید. مثال:
The documents, signed by the CEO, are ready. - 3بیان علت یا زمان: در ابتدای جملات برای ایجاد تنوع ساختاری. مثال:
Driven by curiosity, he opened the box.(به جایBecause he was driven by...). - 4تیترهای خبری: در رسانهها برای صرفهجویی در فضا. مثال:
Bridge, damaged by the storm, remains closed.
- 1خطای فاعل معلق (Dangling Participle): این رایجترین اشتباه فارسیزبانان است. چون در فارسی ما گاهی فاعل را در جملات مجهول حذف میکنیم و ذهن ما به این ساختار عادت دارد، ممکن است بگویید:
Built in 1990, the architect designed the house.این جمله غلط است چون میگوید «معمار در سال ۱۹۹۰ ساخته شده بود!». اصلاح:Built in 1990, the house was designed by the architect. - 2استفاده از شکل دوم فعل (V2): فارسیزبانان گاهی
Past Simpleرا باPast Participleاشتباه میگیرند. مثلاً میگویندThe letter wrote by himدر حالی که باید بگویندThe letter written by him. - 3ترجمه تحتاللفظی «توسط»: در فارسی ما همیشه از «توسط» استفاده میکنیم، اما در انگلیسی، اگر عاملِ فعل مهم نباشد، میتوانید عبارت
by...را هم حذف کنید. حذف زایدِ عاملِ فعل، متن شما را به سطح C1 نزدیکتر میکند.
Past Participle (مجهول) و Present Participle (معلوم) است.The book, written by him... |The man, writing the book... |- 1آیا همیشه باید از ویرگول استفاده کنیم؟ اگر عبارت، اطلاعات غیرضروری (Non-restrictive) باشد، بله. اگر عبارت برای شناسایی اسم ضروری باشد، ویرگول لازم نیست (مثل
The car parked outside is mine). - 2آیا میتوانم این ساختار را در صحبت کردن استفاده کنم؟ بله، اما در محیطهای رسمی یا ارائه کنفرانسها بسیار رایجتر است تا در چتهای دوستانه در تلگرام یا اینستاگرام.
- 3آیا این ساختار همیشه مجهول است؟ بله،
Past Participleدر این ساختار همیشه بار معنایی مجهول دارد. اگر بخواهید معنای معلوم برسانید، باید ازPresent Participle(V-ing) استفاده کنید.

سوالات متداول (8)
It's a common mistake where the participle clause describes the wrong subject. For example, `Walking to the store, the rain started.` implies the rain was walking. You must ensure the subjects match.
Yes, but they sound quite formal. In casual conversation, we usually use `because` or `so`. You might hear them in speeches or formal presentations.
`Seen` describes a state or simultaneous action. `Having been seen` emphasizes that the action was completed *before* the main verb happened.
If the clause comes at the beginning, yes. If it follows the noun it describes (e.g., `The car stolen yesterday...`), you usually don't need a comma unless it's non-defining information.
Yes! Just put `not` at the very beginning. `Not surprised by the news, she continued her work.`
Because the subject of the sentence is the *receiver* of the action in the participle clause. `Struck by lightning, the tree fell` (The tree was struck).
Only with transitive verbs (verbs that take an object) because only they can be made passive.
Yes, `Given the circumstances...` is a very common fixed participle clause used to mean 'Considering the circumstances'.
