Grammar explanation
We use the passive voice to change the focus of the sentence.
My bike was stolen. (passive – focus on my bike)
Someone stole my bike. (active – focus on someone)
We often use the passive:
- when we prefer not to mention who or what does the action (for example, it's not known, it's obvious or we don't want to say)
- so that we can start a sentence with the most important or most logical information
- in more formal or scientific writing.
How we make the passive
We make the passive using the verb be + past participle. We start the sentence with the object.
| Avatar | was | directed by James Cameron. |
| ↓ | ↓ | ↓ |
| Object | + be + | past participle |
It is not always necessary to add who or what did the action.
| My flight | is | cancelled. |
| ↓ | ↓ | ↓ |
| Object | + be + | past participle |
Only the form of be changes to make the tense. The past participle stays the same. Here are examples of the passive in its most common tenses.
| Tense | Example | Structure |
| Present simple | Alioli is made from oil, garlic and salt. | is/are + past participle |
| Present continuous | The hall is being painted this week. | is/are being + past participle |
| Past simple | John F. Kennedy was assassinated in 1963. | was/were + past participle |
| Past continuous | The signs were being put up last week. | was/were being + past participle |
| Present perfect | Oranges have been grown here for centuries. | has/have been + past participle |
| Past perfect | When he got home, he found that his flat had been burgled. | had been + past participle |
| Future simple | The work will be finished next week. | will be + past participle |

Hi nino23,
The passive will normally have an agent phrase (e.g. I wasn't sure whether to apply for the promotion but I was convinced by my colleagues to go for it). Since there is no strong idea of any agent causing the convincing in your example, it's probably an adjective.

Hello,
A quick question, there was an example given at my daughter's English lesson :
This seems to be a successful makeover. Susan/remodel/her cheekbones.
With the correct sentence given as: Susan has had her cheekbones remodeled.
Why "has had" is to be used? Is that because of the Present Simple used in the first sentence.. "seems"?
Hi PiotrM,
This structure is called the causative "have". To "have (something) (done)" means to receive that action from somebody else, normally as a professional service. For example:
As you can see, the structure shows an action. Turning to your example sentence, the action of remodelling must logically have happened before the present moment, so the present perfect "has had ..." is used. A past simple form (Susan had her cheekbones remodelled) is also possible, but the present perfect is preferable because the remodelling is clearly relevant to the present topic of conversation.
Incorrect answers would include Susan (has) remodelled her cheekbones, since Susan received rather than performed this action. Instead, the causative "have" is needed.
I hope that helps to understand it.

Hello, Sir!
1. We seem to miss one book. (Active Infinitive)
2. One book seems to be missed. (Passive infinitive)
3. We seem to be one missed. (one = one book)
Is the sentence 3 passive? Are the sentences 1 and 3 the same?
Thank you in advance for your time.
Hello Sokhomkim,
I'm afraid that none of these sentences are correct. Could you explain in other words what you mean to say with them? For example, if we normally have 10 books but now there are only 9, we could say 'One book is missing' or 'One book seems to be missing' (similar to sentence 2). It's also possible to say 'We seem to be missing one book' (sentence 1). But I don't understand sentence 3.
In the sentences I wrote, 'missing' is an adjective.
Best wishes,

Thank you very much, Sir.
Your example is what I mean.
- We seem to be missing one book. ( "to be missing" is continuous infinitive with the object "one book, isn't it?)
I wanted to know if I can use "the simple infinitive (to miss one book) or it has to be "continuous infinitive (to be missing one book). And can I change your sentence using the passive infinitive?)
- One book seem to be being missed (by us).
Thank you so much for your time.
Hello Sokhomkim,
I think the root of the confusion here is two different meanings of the word 'missing'.
1) The first meaning refers to something that we can't find; in this case, 'missing' is an adjective. So if this sentence means that we can't find one book, then 'to be missing' is not a continuous infinitive. Instead, it is the simple infinitive 'to be' and the adjective 'missing'.
2) The second meaning refers to a person or thing that is not with us and whose absence makes us sad; in this case, it is a form of the verb 'to miss'. Note that normally we use the verb 'miss' in this way to speak of people or situations or animals -- things we have an emotional connection to. It is possible to have this feeling about a book, but more unusual.
So if 'missing' refers to an emotional state in which we find our life incomplete because the book is gone (as if the book were a person you are close to), then 'to be missing' could indeed be a continuous infinitive. That is not how I understood the sentence, but it is a possible meaning.
Hope this helps.
Best wishes,

Hello, Sokhomkim.
What Mr. Moore explains is correct.
1. It seems that one book is missing. (active voice)
2. One book is missing. (passive voice)
Regarding the third sentence, as a native Spanish speaker, I think I understand what you're trying to say. Using only "one" to refer to "a book" in the passive voice is possible, but you need context. Continuing with Mr. Moore's example;
If we usually have 10 books, but now there are only 9, and suddenly someone notices, they may ask: 'Are there only 9 books?' You can respond in the passive voice: 'It seems that one is missing'.
"It seems that one is missing" is a clear and appropriate use of passive voice in this context. It effectively conveys the idea that there is a perception or observation of a missing book without specifying who might have taken it.
I hope this helps.
Hello Glori Flores and Sokhomkim,
Just to be clear, in 'One book is missing', there is no passive voice. It is: 'One book' (a noun phrase subject) + 'is' (link verb) + 'missing' (an adjective).

Hello,
I would like to ask the position of by agent in the passive voice of the present perfect when the sentence has adverbs such as recently, yet,..etc.
1. Jack has typed the article recently.
>>The article has been typed by Jack recently or The article has been typed recently by Jack.
I searched on the Internet and someone said it could be "The article has recently been typed by Jack." It's a good idea, however, I would like to know where the position of "by agent" is really.
2. The police haven’t found the murderer yet.
In this sentence, anything should be noted if the sentence has the adverb "yet" which is usually at the end of the sentence.
