راهنمای فصل

مرور کلی

As a B2 English learner, you're past the basics and ready to truly refine your expression. This chapter is your key to unlocking a more sophisticated and natural way of speaking and writing, making your B2 English grammar shine. We're diving into English connecting information with relative clauses – a powerful tool that transforms choppy sentences into smooth, flowing prose.
Imagine being able to explain complex ideas or describe intricate scenarios with effortless clarity. That's what relative clauses offer!
You'll learn to weave details seamlessly, whether it's showing possession with whose, linking information to places, times, or reasons using where, when, and why, or distinguishing between essential and extra information with defining and non-defining clauses. We’ll even show you how to elegantly shorten your sentences by reducing relative clauses, making your speech and writing more concise and impactful. Plus, for those moments when you need to sound truly professional, we'll cover formal relative clause structures.
Get ready to express your thoughts with newfound precision and confidence!

این گرامر چطور کار می‌کنه

At its heart, a relative clause adds information about a noun (a person, place, thing, or idea) without starting a new sentence. It makes your English sound much more natural and less like a series of short, unconnected statements. Think of them as linguistic bridges.
We start with the basics: whose shows possession, just like his or her but within a clause. For example:
The student whose essay won the prize is incredibly talented.
Here, whose links the student to their essay. Next, relative adverbs (where, when, why) connect details to places, times, or reasons.
Instead of saying
I remember the restaurant. We had our first date there,
you can say
I remember the restaurant where we had our first date.
This is far more elegant and efficient.
The distinction between defining and non-defining relative clauses is crucial and often hinges on commas. A defining clause provides essential information to identify the noun – without it, the meaning changes or is unclear. For instance,
The car that is parked illegally will be towed.
(No commas, essential info).
A non-defining clause, on the other hand, adds extra, non-essential information and is always set off by commas.
My brother, who lives in Canada, is visiting next week.
(With commas, 'who lives in Canada' is just additional detail; I only have one brother).
For even greater conciseness, you can often reduce relative clauses. If the relative pronoun is the subject of the clause and the verb is active, you can remove the pronoun and be verb (if present) and change the main verb to its present participle (-ing form).
The man who is standing near the door is my boss
becomes
The man standing near the door is my boss.
If passive, use the past participle:
The documents which were signed yesterday are ready
becomes
The documents signed yesterday are ready.
Finally, for a touch of formality, particularly in written English, you can shift prepositions to the beginning of the clause with 'which' or 'whom'.
Instead of
This is the problem that I referred to,
you can say
This is the problem to which I referred.
This instantly elevates your language.

اشتباهات رایج

  1. 1✗ Using who instead of whose for possession.
✗ "That's the student who grades are always top-notch."
✓ "That's the student whose grades are always top-notch."
Explanation: Whose is possessive, meaning belonging to whom or of which. Who is a subject pronoun.
  1. 1✗ Incorrect comma usage for defining and non-defining clauses.
The book, that I borrowed from you, was excellent.
The book that I borrowed from you was excellent.
(Defining – essential information to identify *which* book)
My old car, which was quite reliable, finally broke down.
(Non-defining – 'which was quite reliable' is extra info about *my old car*, already identified)
Explanation: That is typically used for defining clauses (no commas). Which can be used for both, but for non-defining clauses (with commas), which is the only correct choice.
  1. 1✗ Incorrectly reducing clauses, especially in the passive voice.
The report sending to the client needs final approval.
The report sent to the client needs final approval.
Explanation: The report isn't sending itself (active); it is sent (passive). When reducing a passive relative clause, use the past participle.

سؤالات رایج

Q

Is that always interchangeable with which in defining relative clauses?

In informal English, yes, that and which are often interchangeable for things in defining clauses. However, that is generally preferred, especially for objects. For people, use who or that. Remember, for non-defining clauses (with commas), you *must* use which for things, and who for people.

Q

Can I always reduce a relative clause?

Not always. You can only reduce a relative clause if the relative pronoun (who, which, that) is the subject of the clause and the verb is active (use -ing) or passive (use past participle). You cannot reduce clauses where the relative pronoun is the object (e.g.,

The book that I read was good
).

Q

What's the main difference between where and in which?

Both can indicate location. Where is a more common and informal relative adverb. In which is a more formal and often more precise structure, especially common in academic or formal writing. For example,

The city where I live is bustling
vs.
The study described the conditions in which the experiment was conducted.

بافت فرهنگی

Native English speakers frequently use these structures to create flow and avoid repetitive sentences. While formal structures like to whom or in which are common in academic writing or official communications, everyday conversation often opts for simpler phrasing (
the person I spoke to
instead of
the person to whom I spoke
). Reduced relative clauses are particularly prevalent in both spoken and written English, making communication more efficient and dynamic.
Mastering these nuances will help you sound truly fluent and adaptable in various contexts.

💡

تست 'who is' رو انجام بده!

اگه شک داری کدوم رو بنویسی، ببین می‌تونی جاش 'who is' یا 'who has' بذاری و جمله معنی بده؟ اگه شد، باید از who's استفاده کنی. اگه نه، حتماً whose درسته! مثلاً: "Who's calling me right now?"

💡

فرمول سه مرحله‌ای

اگه اسم قبل از قیدت مکان، زمان یا دلیله، معطل نکن و مستقیم برو سراغ این سه تا؛ اینطوری جمله‌ت خیلی روون‌تر از استفاده از 'which' میشه:
This is the place where I work.

  • Noun + whose + noun
  • Noun + where/when/why
  • Noun, [extra info], verb
  • Noun + [V-ing/V3]
  • Preposition + whom/which

اشتباهات رایج

Do not use a personal pronoun after 'whose'. 'Whose' already functions as the possessive pronoun.

Wrong: The woman who her bag was stolen.
صحیح: The woman whose bag was stolen.

When using a formal structure, the preposition moves before the pronoun, and the redundant pronoun at the end is removed.

Wrong: The house that I live in it.
صحیح: The house in which I live.

Do not repeat the subject after a relative clause. The relative pronoun is already the subject.

Wrong: My brother, who lives in London, he is a doctor.
صحیح: My brother, who lives in London, is a doctor.

سوالات رایج (6)

کلمه whose یه ضمیر موصولی ملکیه. یعنی برای نشون دادن مالکیت یا رابطه نزدیک بین دو تا اسم استفاده میشه تا جمله‌ها رو نرم به هم وصل کنه. مثلاً:
The artist whose painting sold...
بله، صد در صد! با اینکه بیشتر واسه آدم‌ها می‌شنویم (مثل
the student whose laptop
)، ولی واسه اشیا و مفاهیم هم کاملاً درسته. مثلاً:
the company whose technology...
قیدهای موصولی (مثل where, when, why) جملات رو به اسم‌های قبلشون وصل می‌کنن تا اطلاعات بیشتری درباره مکان، زمان یا دلیل بدن. مثلاً:
The house where I live.
چون جمله‌ت رو کوتاه‌تر و طبیعی‌تر می‌کنه. به جای اینکه بگی 'the house in which'، خیلی راحت می‌گی:
The house where I live.
تفاوت اصلی توی اینه که آیا اون اطلاعات برای شناسایی اسم ضروریه (Defining) یا فقط یه توضیح اضافیه (Non-defining). همین موضوع تعیین می‌کنه ویرگول بذاریم یا نه. مثلاً:
The man who called you is here.
وقتی که اسم قبلاً کاملاً شناسایی شده (مثل اسم خاص یا اسمی که با my مشخص شده) و تو فقط داری یه توضیح اضافه میدی. مثل:
My cat, which is sleeping, is cute.
