حالت مجهول با افعال کمکی (می تواند انجام شود)
Modal و be و Past Participle. از اینا استفاده میکنی تا بگی چی «اتفاق میافته»، نه «کی» کاری رو میکنه.
Grammar Rule in 30 Seconds
Use modal passives to focus on what needs to happen rather than who is doing it.
- Combine a modal (can, must, should) with 'be' and a past participle: 'It can be fixed.'
- For negatives, place 'not' immediately after the modal: 'It cannot be fixed.'
- In questions, move the modal to the front: 'Can it be fixed?'

Smart Tips
Use 'could be' or 'might be' instead of 'you should'. It sounds less like you are giving orders.
Check if the subject is 'doing' the action. If not, insert 'be' and change the verb to V3.
Remember that 'must not be' means it is forbidden, not that it isn't necessary.
Think of the modal and 'be' as a sandwich, with the subject as the filling.
تلفظ
Weak 'be'
In the phrase 'can be done', the word 'be' is usually unstressed and very short.
Modal Stress
Modals like 'must' or 'should' are often stressed to emphasize the necessity or advice.
Rising intonation for questions

نکات فرهنگی
British speakers often use 'ought to be' more frequently than Americans in formal advice.
Passive modals are used to avoid direct blame. Instead of 'You must fix this', a manager says 'This must be fixed' to sound less aggressive.
Public signs in English-speaking countries rely heavily on 'must be' and 'shall be' for authority.
Modal verbs in English come from Old English 'preterite-present' verbs, which originally had different meanings (e.g., 'can' meant 'to know'). The passive construction 'be + past participle' developed later as a way to express the patient of an action.

Yes, but only in informal speech. For example, `It might get broken` is okay with friends, but in an essay, use `It might be broken`.
They follow the same rule: `The bill has to be paid` or `The law ought to be obeyed`. Just add `be + V3` after the 'to'.
Not always, but it is *more* formal than the active voice. We use it in daily life for rules and instructions.
Move the modal to the front: `Can it be done?` or `Should the room be painted?`. The `be` stays after the subject.
Yes! `The work can be done by a professional.` However, we usually use the passive when the person isn't important.
It is `must not be` (prohibition) or `doesn't have to be` (lack of necessity). Be careful with the meaning shift!
Yes! `The package will be delivered tomorrow.` It follows the exact same pattern as other modals.
Because modal verbs are always followed by the base form of a verb. The base form of 'is/am/are' is `be`.
