Map the acceptable condition, negative exception and precaution.
TF30 · B1 Grammar · 30 min
unless, as long as, provided that, and in case
Choose the precise linker for a negative exception, an acceptable limit, a formal requirement or a precaution.
Why this lesson matters · เหตุผลที่เรียนบทนี้
For learners: Choose the precise relationship between condition and result—exception, acceptable limit, formal requirement or precaution—and negotiate a workable agreement.
For teachers: The route starts with communicative purpose, maps each purpose to linker and form, repairs false matches—especially in case versus if—then applies the choices in an independently negotiated four-part agreement.
สำหรับผู้เรียน: เลือกความสัมพันธ์ระหว่างเงื่อนไขกับผลให้แม่นยำ—ข้อยกเว้น ขอบเขตที่ยอมรับได้ ข้อกำหนดอย่างเป็นทางการ หรือการป้องกันล่วงหน้า—แล้วเจรจาข้อตกลงที่ใช้ได้จริง
สำหรับครู: ลำดับเริ่มจากจุดประสงค์การสื่อสาร เชื่อมแต่ละจุดประสงค์กับคำเชื่อมและรูปประโยค แก้การจับคู่ที่ผิดโดยเฉพาะ in case กับ if แล้วนำไปใช้เจรจาข้อตกลงสี่ส่วนอย่างอิสระ
Your Goal
Negotiate four practical terms using unless, as long as, provided that and in case accurately, reject or revise one unsuitable condition and confirm one useful precaution.

Why this lesson matters
Small linker changes alter the agreement. They can remove an option, set an acceptable limit, impose a formal requirement or explain why a precaution happens before a possible event.

Teacher Lesson Plan
Ask what relationship the speaker needs before showing a linker: negative exception, acceptable limit, formal requirement or precaution. Treat `in case` as preparation before a possibility, never as a direct synonym for `if`.
| Stage | Teacher move | Evidence to collect |
|---|---|---|
| 1 · Meaning | Match four practical purposes before showing the linkers. | Eight purpose decisions |
| 2 · Form | Build both clause orders and ordinary future-time forms. | Eight accurate linker sentences |
| 3 · Repair | Contrast preparation before an event with response after a condition. | Six if/in case decisions + three repairs |
| 4 · Plan | Draft four negotiable terms and one safeguard from learner context. | One four-part agreement map |
| 5 · Check | Use two accents as input, then challenge one unsuitable term. | Two listening maps + first negotiation |
| 6 · Perform | Score the first agreement, target one mismatch and retry only that term. | Independent four-part agreement |
Stage 1 · Match four condition purposes
Start with the relationship the plan needs: negative exception, acceptable limit, formal requirement or precaution.
STUDENT TASK
EXCEPTION / LIMITSay what blocks the result or what makes it acceptable.
REQUIREMENTState a condition that must be met before agreement.
PRECAUTIONPrepare now because a possible event may happen later.
| Planning need | Your purpose | Why it matters |
|---|---|---|
| The outdoor event cannot continue if the storm warning becomes severe. | exception / limit / requirement / precaution | identify the blocking condition |
| The team accepts the new date only when everyone can attend. | exception / limit / requirement / precaution | set an acceptable boundary |
| Payment must arrive before the supplier confirms the order. | exception / limit / requirement / precaution | state a formal condition |
| Bring a charger now because the battery may run low later. | exception / limit / requirement / precaution | prepare before a possibility |
| You will take the train except when the line is closed. | exception / limit / requirement / precaution | name the negative exception |
| You can borrow the car only if you return it by six. | exception / limit / requirement / precaution | set the accepted limit |
| The venue agrees only when the deposit is paid. | exception / limit / requirement / precaution | make the requirement explicit |
| Save an offline map now because the signal may disappear. | exception / limit / requirement / precaution | prepare in advance |
Check the purpose match
Negative exception: 1 and 5. Acceptable limit: 2 and 6. Formal requirement: 3 and 7. Precaution: 4 and 8.
- Classify all eight planning needs before looking at the linkers.
- Underline the phrase that controls each purpose.
- Explain one decision from each purpose in your own words.
Meaning first: “What blocks the plan?” · “What limit is acceptable?” · “What requirement must be met?” · “What should we prepare before a possibility?”
Finish evidenceEight purpose decisions and four spoken justifications.
Teacher Help · Stage 1
Keep the linkers hidden until the purpose sort is complete. Ask whether the speaker blocks an outcome, accepts it within a limit, imposes a requirement or prepares before a possible event. Do not reduce `in case` to “if”.
Stage 2 · Build the four linker clauses
Connect each purpose to its linker, practise both clause orders and keep ordinary future-time clauses accurate.
STUDENT TASK
| Linker and purpose | Core form | Example |
|---|---|---|
| unless · negative exception | unless + positive clause (= if … not) | We’ll go outside unless the storm gets worse. |
| as long as · acceptable limit | result + as long as + condition | You can use the room as long as you leave it tidy. |
| provided that · formal requirement | provided that + condition, result | Provided that the deposit arrives today, we’ll confirm the order. |
| in case · precaution | prepare now + in case + possible event | Take a charger in case the battery runs low. |
The form and punctuation rule
For ordinary future meaning, use a present form after the linker: “unless it rains”, not “unless it will rain”.
When the linker clause comes first, use a comma before the result. When it comes second, a comma is usually unnecessary.
- Rewrite “if the weather does not improve” with unless.
- Complete one acceptable limit with as long as.
- Write one formal requirement with provided that.
- Write one preparation-before-possibility message with in case.
- Reverse the clause order in all four messages and add or remove commas safely.
Check a safe unless rewrite
“We’ll postpone the trip unless the weather improves” means “We’ll postpone the trip if the weather does not improve.” Do not add another negative after unless.
Finish evidenceEight accurate sentences: each linker used in both clause orders with safe punctuation.
Teacher Help · Stage 2
Correct purpose before punctuation. Watch for double negatives after `unless`, `will` after the linker and overformal `provided that` in casual small requests. Have learners read both clause orders aloud to preserve meaning.
Stage 3 · Separate in case from if
Decide whether an action happens before a possible event as preparation or only after a condition becomes true.
STUDENT TASK
| Intended action | Your choice | Meaning to explain |
|---|---|---|
| Take an umbrella now because rain is possible. | if / in case | preparation before the event |
| Open the umbrella only when rain begins. | if / in case | response after the condition |
| Save the address offline now because the signal may disappear. | if / in case | advance safeguard |
| Call support only after the connection fails. | if / in case | conditional response |
| Pack medicine now because you may feel unwell. | if / in case | preparation before travel |
| Take the medicine only when symptoms appear. | if / in case | action after evidence |
Check if or in case
in case: 1, 3, 5 — preparation happens before the possible event. if: 2, 4, 6 — the action happens only when the condition becomes true.
Critical contrast: “Take a charger in case the battery runs low” means take it now as a precaution. “Charge the phone if the battery runs low” means act after the condition occurs.
- Choose if or in case for all six actions and explain the timing.
- Repair: “Take an umbrella if it rains later” when the intended meaning is preparation now.
- Repair: “Call me in case the train is cancelled” when the intended meaning is call only after cancellation.
- Repair: “We’ll go unless it doesn’t rain” when the intended meaning is go except when it rains.
Check the repairs
“Take an umbrella in case it rains later.” · “Call me if the train is cancelled.” · “We’ll go unless it rains.”
Finish evidenceSix if/in case decisions, six timing explanations and three accurate repairs.
Teacher Help · Stage 3
Use a simple timeline: precaution now → possible event later for `in case`; condition becomes true → response for `if`. Do not correct by translation alone. Require learners to say when the first action occurs.
Stage 4 · Draft a four-part agreement
Turn four different condition purposes into negotiable terms and one sensible safeguard.
STUDENT TASK
1 · PLANChoose an event, purchase, trip or project with a real decision.
2 · FOUR TERMSAdd one exception, one acceptable limit, one requirement and one precaution.
3 · CHECKDecide whether every term is fair, clear and practical.
| Purpose | Planning note | Negotiation question |
|---|---|---|
| Negative exception | outdoor event · continue unless storm warning becomes severe | What exactly would stop the plan? |
| Acceptable limit | finish by six · use venue as long as room is tidy | Is this limit practical for both sides? |
| Formal requirement | deposit today · booking confirmed provided that payment arrives | Can both sides verify the requirement? |
| Precaution | bring portable light in case power fails | Does this prepare us before the risk? |
- Choose one real event, purchase, trip or project.
- Write notes only: decision · purpose · condition · result/action.
- Draft one term with each of the four linkers.
- Mark one term that a partner may reject or revise.
- Confirm that the in case action happens before the possible problem.
Finish evidenceOne four-part agreement map, one challenge target and one clear precaution.
Teacher Help · Stage 4
Keep notes short so Stage 6 is negotiated, not read. Test whether `provided that` sounds appropriately formal and whether the `in case` action is a real precaution. Require one term that is genuinely open to revision.
Stage 5 · Listen, map and negotiate
Recover the permissions, limits, requirements and safeguards, then challenge one condition before your first agreement.
STUDENT TASK
British English
American English
Supplier agreement
Identify the formal requirement, acceptable limit and backup preparation.
- Listen once for the plan. On the second listen, note decision · condition · linker · safeguard.
- Retell one condition and one precaution from each recording.
- Give your four planned terms to a partner.
- Your partner challenges the marked term: “Is this fair, necessary and clear?”
- Defend it or revise the linker, condition or result.
- Confirm the final four terms and one backup action.
Useful negotiation frame“We can agree to ___ as long as ___. Provided that ___, we’ll ___. Let’s ___ in case ___. We won’t ___ unless ___.”
Finish evidenceTwo listening maps, one first negotiation, one challenged/revised term and one confirmed safeguard.
Teacher Help · Stage 5
Audio never starts automatically. Use the British recording first and the American recording for transfer. If the learner hears the linker but not its purpose, replay the decision and condition together. Do not reveal a model before the learner identifies the relationship.
Stage 6 · Final Practice: negotiate, safeguard and retry
Reach an independent four-part agreement and improve one precise linker–purpose weakness.
FINAL PRACTICE
Propose → challenge → revise → confirm → retry
- Use notes only: decision · purpose · condition · result/action.
- Negotiate one event, purchase, trip or project using all four linkers once.
- Your partner rejects or questions one term and explains why it is unclear, unfair or impractical.
- Revise that term without losing the intended condition relationship.
- Confirm the final exception, accepted limit, formal requirement and precaution.
- After one feedback target, retry only the weakest linker–purpose–result connection.
Planning example: outdoor event · continue unless storm warning is severe · use venue as long as room is tidy · booking confirmed provided that deposit arrives · bring portable light in case power fails.
Score the first independent performance
MEAN · MeaningThe listener understands the negative exception, acceptable limit, formal requirement and precaution, including why in case is not if.
FORM · FormThe learner controls all four linkers, both clause orders, ordinary present forms and safe punctuation without double negatives.
USE · Real useThe learner reaches a four-part agreement, responds to a challenge, revises one term and confirms a workable safeguard.
0 · Not yetOne or more condition relationships are unclear, so the listener cannot state the final agreement or precaution reliably.
1 · With supportThe agreement becomes clear after a purpose question, linker cue or focused correction.
2 · IndependentPurpose, form, negotiated result and safeguard are clear without a prompt.
Result: 0–2 Rebuild · 3–4 Developing · 5–6 B1 mastery evidence.
Finish evidenceFirst four-part agreement + one challenged and revised term + one confirmed safeguard + one focused retry.
Teacher Help · Stage 6
Score the first independent agreement across MEAN, FORM and USE. Give one target only: “name the condition purpose”, “remove the double negative”, “use present after the linker”, “separate in case from if” or “make the safeguard practical”. Keep the original score and record whether the focused retry improves that target.
