Hook — A Fun Real-Life Story to Grab Attention
Imagine you are at a famous Indian railway station like Chhatrapati Shivaji Maharaj Terminus in Mumbai. You see a sign that says, "Tickets must be shown on demand." You wonder, “Must I show my ticket?” Or when the announcement says, "Passengers should keep their belongings safe," you think, “Should I be careful with my bag?” These words must and should are examples of modals — little helpers that tell us about possibility, necessity, or advice. Also, when you see a sign, "Lost items are kept at the help desk," you notice the verb is in the passive voice, meaning the action is done to the subject. Today, we will explore how modals and passives work in English — essential tools for clear and polite communication!
Core Concepts — Modals and Passives Explained
Modals express ability, possibility, permission, obligation, advice, or certainty. They are always followed by the base form of the main verb (without 'to').
| Modal | Use | Example |
|---|---|---|
| Can | Ability, Permission | She can speak Hindi fluently. |
| Must | Obligation, Necessity | You must wear a helmet while riding a bike. |
| Should | Advice | You should drink plenty of water. |
| May | Permission, Possibility | May I come in? |
In the passive voice, the subject receives the action rather than doing it. It is used to focus on the action or when the doer is unknown or unimportant.
Active: The gardener waters the plants.
Passive: The plants are watered by the gardener.
| Tense | Passive Form | Example (Active → Passive) |
|---|---|---|
| Present Simple | am/is/are + past participle | They clean the temple → The temple is cleaned. |
| Past Simple | was/were + past participle | He painted the wall → The wall was painted. |
| Future Simple | will be + past participle | They will build a school → A school will be built. |
Key Formulas / Rules

Example: The letter was sent by Ravi.
Modal + Passive:
Subject + Modal + be + Past Participle
Example: The homework must be done by evening.
Did You Know?
The word “modal” comes from the Latin word modus, meaning “manner” or “mode.” Modals show the manner in which something happens — like possibility, ability, or permission. Also, in Indian English, modals like “shall” are commonly used in formal speech, especially in polite requests, such as, “Shall I help you?” This reflects our cultural politeness and respect.
Exam Tips — Common Mistakes & Board Exam Patterns
- Do not add ‘to’ after modals. For example, “She can to swim” is wrong. Correct: “She can swim.”
- Remember the correct form of ‘be’ in passive voice. Use am/is/are for present, was/were for past, and will be for future.
- When using modals in passive voice, always use ‘be’ + past participle. Example: “The work must be finished.”
- In the CBSE Class 10 board exam: Questions on modals and passive voice appear in grammar sections and writing tasks like letters and notices.
- Practice rewriting sentences from active to passive and vice versa. This is a common question type.
- Watch out for irregular past participles. For example, “write” → “written”, “go” → “gone”.
