B1 — Focusing on Actions with the Passive Voice

B1 · متوسط فصل 7

Focusing on Actions with the Passive Voice

Q: پایهایترین ساختار جمله مجهول چیه؟

پایه و اساس ساختار مجهول یه شکل از فعل "to be" (مثل is, was, are) هست که بعدش اسم مفعول (V3) فعل اصلی میاد. مثلاً: "The book is read."

Q: چرا به جای جمله معلوم از مجهول استفاده میکنیم؟

ما از مجهول استفاده میکنیم وقتی که کسی یا چیزی که کار رو انجام میده (فاعل) معلوم نیست، مهم نیست، یا وقتی میخوایم روی خود عمل یا گیرندهی عمل تأکید کنیم. مثلاً: "The window was broken."

Q: Can I use 'by' in every passive sentence?

You can, but you shouldn't. Only use `by` if the person doing the action adds important information. 'The book is written by Steve' is good. 'The room is cleaned by a cleaner' is redundant.

Q: What is the difference between 'is made of' and 'is made from'?

Use `is made of` when you can still see the original material (e.g., 'The chair is made of wood'). Use `is made from` when the material has changed (e.g., 'Paper is made from wood').

Q: ایده اصلی Past Simple Passive چیه؟

ایده اصلی اینه که روی عملی که تو گذشته اتفاق افتاده و "چیزی که روی فاعل انجام شده" تمرکز کنی، نه اینکه چه کسی اون کارو انجام داده. مثلاً "The car was repaired" روی ماشین و تعمیر شدنش تاکید داره، نه مکانیک.

Q: چطور Past Simple Passive رو میسازیم؟

با ترکیب گذشته ساده فعل "to be" (was برای فاعل مفرد، were برای فاعل جمع) با شکل سوم فعل اصلی (V3). مثلاً "The report was written" یا "The gifts were given".

راهنمای فصل

مرور کلی

Welcome to

Focusing on Actions with the Passive Voice,

your guide to mastering a truly versatile aspect of B1 English grammar! Have you ever wanted to talk about an event or achievement without always having to say who was responsible? Perhaps you’ve read a news report and noticed how things are described in a very objective way.

That’s the magic of the passive voice. This chapter is designed to help you shift your focus from the doer to the action itself, giving you more flexibility and sophistication in your English.

By understanding how to use be with a past participle (V3), you'll unlock the ability to describe what happens to things (Present Simple Passive) and what happened to things (Past Simple Passive). We’ll also explore how to still give credit with by when the doer is important, and how professional English uses the passive voice for reporting news and rumors. This will significantly improve your ability to communicate clearly and confidently, allowing you to sound more natural and professional in various situations.

Get ready to enhance your English focusing on actions with the passive voice!

این گرامر چطور کار می‌کنه

At its heart, the passive voice is about changing the focus of a sentence. Instead of saying *who* did something (the active voice), you focus on *what* was done or *what* something happened to. The fundamental building block for all passive sentences is the auxiliary verb 'be' followed by the past participle (V3) of the main verb.

For example,

The car is repaired

The letter was written.

Let’s look at how this core structure adapts across different situations. For actions happening regularly or states of being, we use the Present Simple Passive. This is formed with am/is/are + V3.

If a problem with your car is fixed every year, you might say,

The engine is checked annually.

Here, the focus is on the engine and the regular action, not necessarily who checks it. When we talk about past actions where the doer is unknown, unimportant, or obvious, we use the Past Simple Passive. This uses was/were + V3.

For instance,

The ancient city was discovered in the desert

focuses on the city and the discovery, not who discovered it.

Sometimes, even in the passive voice, the doer *is* important. In these cases, you can give credit with by by adding 'by' followed by the agent at the end of the sentence.

The Mona Lisa was painted by Leonardo da Vinci

still highlights the painting first, but acknowledges the artist.

This is particularly useful when the action is more significant than the actor, but the actor is still noteworthy. Finally, the passive voice is extremely common for reporting news and rumors. This allows for objectivity and formality, often when the source isn't clear or needs to be generalized.

Phrases like

It is believed that...

The new policy was announced yesterday

are perfect examples, focusing on the information itself rather than the speaker or announcer.

اشتباهات رایج

Learning the passive voice can sometimes lead to a few common errors. Let's make sure you avoid them!

1✗ Incorrect form of 'be' or forgetting it

* ✗ The book written last year.

* ✓ The book was written last year.

* *Explanation:* You must always include a form of the verb 'be' (am, is, are, was, were) in passive sentences.

1✗ Using the wrong past participle

* ✗ The report is wrote by my colleague.

* ✓ The report is written by my colleague.

* *Explanation:* Remember to use the correct past participle (V3) form of the verb, not the past simple form.

1✗ Confusing active and passive when using 'by'

* ✗ She was cooking the dinner by her.

* ✓ The dinner was cooked by her.

* *Explanation:* The agent with 'by' comes after the passive verb structure, indicating the person who performed the action. The original sentence was trying to force a passive structure onto an active meaning.

مکالمات واقعی

Here’s how the passive voice sounds in everyday chats:

Hey, what happened to the old building on Elm Street?

Oh, it was demolished last month. A new apartment complex is being built there now.

Did you hear about the new art exhibit?

Yes, I did! I heard a lot of the sculptures were created by local artists. It is said to be very impressive.

This report looks great. Who put it together?

Actually, the data was collected by the whole team, and then the final presentation was designed by Sarah.

سؤالات رایج

Why is English focusing on actions with the passive voice important for B1 learners?

It's crucial for understanding news, formal reports, and sounding more sophisticated. It allows you to describe situations where the action or result is more important than who did it, which is very common in English.

When should I definitely use by in a passive sentence?

Use by when the agent (the person or thing doing the action) is important or interesting to know, but you still want to keep the focus on the action or the recipient of the action. If the agent is unknown, unimportant, or obvious, you can omit by.

Can the passive voice be used in questions?

Absolutely! Just like active sentences, passive sentences can be turned into questions. For example:

Was the car repaired?

Is the message understood?

How can I practice using the passive voice effectively?

Try describing processes (e.g.,

How coffee is made

), summarizing news articles, or rewriting active sentences you find into passive ones. Listening to news broadcasts also helps you hear it naturally.

بافت فرهنگی

In English, the passive voice is more prevalent in formal, academic, scientific, and journalistic writing. It helps maintain objectivity and can make reports sound more authoritative by depersonalizing statements. For instance,

Mistakes were made

sounds more formal and less accusatory than You made mistakes. In informal, everyday conversations, the active voice is generally preferred, as it’s more direct and personal.

Overusing the passive voice in casual talk can sometimes make you sound overly formal or even evasive, so it's all about choosing the right tool for the right situation!

چطور جمله‌ی مجهول رو تشخیص بدیم؟

ببین یه فرم از فعل to be (مثل is, was, are, were, been, being) حتماً اومده باشه و بلافاصله بعدش فعل به صورت اسم مفعول (V3) باشه. اگه این دو تا رو ندیدی، احتمالاً مجهول نیست. به همین راحتی!

The car is washed.

The Zombie Test

If you can add 'by zombies' after the verb and the sentence still makes sense, it's passive! (e.g., 'The house is cleaned... by zombies').

💡

دنبال "Was/Were" بگرد

همیشه حواست باشه قبل از فعل اصلی، حتماً was یا were باشه. اگه نباشه، یعنی داری جمله رو به صورت معلوم میگی، یا یه اشتباه گرامری کردی!
