Session 1: Day one: the outbreak
Objectives
- Discover the scenario and its vocabulary
- Make deductions with must, might, can't
- Give a short emergency announcement
To understand an emergency, guess what is happening and give instructions, we need the outbreak words (outbreak, infected, curfew, shelter, supplies, rumour), imperatives for instructions and modals of deduction (it must be serious, it can't be a joke).
Warm-up
The teacher reads a fictional radio alert: 'Stay indoors. Do not open your door.' Students list five questions they would ask.

Grammar lesson: modals of deduction: must, might, can't
For the teacher: how to run it (8 to 10 minutes)
- Read the radio alert in a calm voice. Ask: is it real? is it a joke? Collect answers on the board.
- Draw the certainty line: can't be (no), might be (maybe), must be (yes). Students copy.
- Show that deduction needs a reason: “It must be serious because the army is on the roads.”
- Quick check, then exercises, then the activities and the emergency announcement.
Rule
To guess from clues, use a modal + base verb. must: I am almost sure it is true. might / may / could: it is possible. can't: I am almost sure it is impossible. Always add the clue.
Form
- modal + base verb: The radio might stop.
- modal + be + adjective / noun: It must be serious.
- past: modal + have + past participle: They must have closed the roads.
- the opposite of must is can't, not mustn't
Use
- To react to the broadcast and the clues.
- In the role play, the presenter guesses what the caller sees.
- Never say must without a reason: because, since, so.
Examples from the lesson
- The shops must be empty.
- The radio might stop.
- It can't be a joke: the army is on the roads.
- The phone network is slow; it might stop soon.
Common mistakes
- Not
It must to be serious., but It must be serious. - Not
It mustn't be a joke., but It can't be a joke. - Not
It might is a film., but It might be a film. - Not

Quick check (2 minutes, hands up or mini whiteboards)Must, might or can't?
- Everyone is talking about it: it ______ be serious.
- The network is slow: it ______ stop.
- The whole country is affected: it ______ be a film.
- My neighbour has a car: he ______ have left.
Show the answers
1. must. 2. might. 3. can't. 4. might (or must, with a stronger clue).
Exercises
EntryRecognition. Say how sure the speaker is: yes (Y), maybe (M), no (N).
- It must be an outbreak.
- The bridge might be closed.
- It can't be a drill: the soldiers look scared.
- The radio could stop tonight.
- The shops must have run out of water.
- It can't have started here.
Show the answers
1. Y. 2. M. 3. N. 4. M. 5. Y. 6. N.
CoreTransformation. Rewrite with must, might or can't.
- I'm sure the roads are blocked.
- Perhaps the school is a shelter.
- I'm sure it isn't a joke.
- It's possible the army will help us.
- I'm sure they heard the alert.

Show the answers
1. The roads must be blocked. 2. The school might be a shelter. 3. It can't be a joke. 4. The army might help us. 5. They must have heard the alert. 6. The infection can't have started in our street. 7. The curfew might be earlier tomorrow.
StretchProduction. Look out of the window of a classroom in the story. Write five deductions with a clue each.
Show the answers
For example: There are no cars, so the roads must be closed. The lights are off; the power might be down. A helicopter is flying low: it must be the army. Nobody is running, so the horde can't be near. The shop door is open; someone might have taken supplies.
Going further (for students heading to language studies)Advanced. Use deduction in the passive and in questions. Rewrite.
- Someone must have warned the army. (passive)
- Is it possible that the virus came from the lab? (Could ...?)
- I'm sure nobody has seen the patient zero. (can't)
Show the answers
1. The army must have been warned. 2. Could the virus have come from the lab? 3. Nobody can have seen patient zero. Passive deduction is common in news reports; could + have + participle asks a cautious question about the past.

Role play
Student A is a radio presenter, Student B calls the radio from a blocked road. Ask and answer questions.
Figures of speech in the documents
Broadcast: “The infected become violent after a bite.” Vocabulary: “horde: a huge moving crowd”
The radio never says “zombies”: it says the infected, a medical word that is softer and avoids panic. That is a euphemism. A horde was first a wandering army or tribe: calling a crowd of infected a horde is a metaphor that makes it sound like an invasion.
EntryWhich word does the radio use instead of “zombies”?
Show the answers
the infected.
CoreWhy does an official message choose a euphemism?
Show the answers
To stay calm and precise, and to avoid panic: a medical word sounds controlled.
StretchRewrite one sentence of the broadcast as a panicked rumour, without euphemism. Then explain the difference.
Show the answers
For example: Zombies are everywhere, they eat people, run! The rumour is emotional and vague; the broadcast is calm and gives instructions.
