Conditions and safeguards
Track the minimum requirement, the exception and each side’s commitment.
TF30 · B2 GRAMMAR · 30 MIN
Conditional Alternatives without If
Negotiate safeguards, limits and consequences precisely—without repeating if for every condition.
Why this lesson matters · เหตุผลที่เรียนบทนี้
For learners: Expand conditional choice into B2 negotiation by controlling requirements, exceptions, proposals, fallbacks and consequences.
For teachers: Completed B1 conditional choices feed this B2 alternatives step, followed by formal C1 inversion and C2 conditional nuance.
สำหรับผู้เรียน: พัฒนาการเลือกเงื่อนไขสู่การต่อรองระดับ B2 โดยควบคุมข้อกำหนด ข้อยกเว้น ข้อเสนอ ทางเลือกสำรอง และผลลัพธ์
สำหรับครู: ทักษะการเลือกเงื่อนไขระดับ B1 นำเข้าสู่ทางเลือกการต่อรองระดับ B2 ก่อนต่อด้วย inversion ระดับ C1 และนัยเงื่อนไขระดับ C2
Your Goal
By the end of this lesson, you can negotiate four conditions using distinct conditional alternatives, clarify two consequences, and produce one balanced agreement.
คำอธิบายภาษาไทย
เมื่อจบบทเรียน คุณจะต่อรองเงื่อนไข 4 ข้อโดยใช้รูปแบบอื่นแทน if ได้อย่างแตกต่าง ชี้แจงผลลัพธ์ 2 ข้อ และสรุปข้อตกลงที่สมดุล 1 ฉบับได้
Why this lesson matters
Real agreements need more than simple if-clauses. Speakers mark minimum requirements, exceptions, imagined proposals and consequences differently so both sides know what must happen, what is flexible and what follows if a condition fails.
ภาษาไทย: ข้อตกลงจริงต้องใช้มากกว่า if-clause แบบเดียว ผู้พูดต้องแยกข้อกำหนดขั้นต่ำ ข้อยกเว้น ข้อเสนอสมมติ และผลที่จะตามมา เพื่อให้ทั้งสองฝ่ายรู้ว่าส่วนใดจำเป็น ส่วนใดยืดหยุ่นได้ และจะเกิดอะไรขึ้นหากเงื่อนไขไม่สำเร็จ

Teacher Lesson Plan
Begin with the relationship between condition and consequence. Ask whether the speaker is setting a minimum requirement, naming an exception, imagining a proposal or warning about a fallback before selecting the grammar.
| Stage | Teacher move | Evidence to collect |
|---|---|---|
| 1 · Map | Label condition, consequence and intended relationship. | 8 logic maps |
| 2 · Select | Match six alternatives to distinct meanings. | 6 justified choices |
| 3 · Control | Check negation, scope, tense and commitment. | 6 controlled versions |
| 4 · Repair | Repair five logic or scope errors. | 5 minimal repairs |
| 5 · Transfer | Trace two accent-varied negotiations. | 2 agreement maps |
| 6 · Perform | Score MEAN/FORM/USE and target one retry. | Balanced agreement + retry |
Stage 1 · Map the condition and consequence
Identify the logic first; different forms package different relationships.
STUDENT TASK
CONDITIONWhat must, may or might happen
RELATIONRequirement, exception, proposal or fallback
CONSEQUENCEWhat follows, changes or fails
| Message | Condition | Relationship | Consequence |
|---|---|---|---|
| We can extend the deadline provided that the first draft arrives Friday. | first draft arrives Friday | minimum requirement | deadline can extend |
| Send the confirmation today; otherwise, the slot will be released. | confirmation does not arrive today | fallback warning | slot is released |
| Supposing we reduced the scope, could you meet the date? | scope is reduced | imagined proposal | meeting date becomes negotiable |
- Map condition, relationship and consequence in eight messages.
- State whether the condition is positive, negative, explicit or inferred.
- Mark what each speaker commits to.
- Identify one message with an unstated fallback.
- Paraphrase each relation with an if-clause without changing meaning.
Finish evidenceEight condition–relationship–consequence maps.
Teacher Help · Stage 1
Do not accept a paraphrase that changes the direction of the condition. Unless X normally means if not X, but the resulting clause must still express the same exception and consequence.
Stage 2 · Distinguish six near-neighbour forms
Choose the expression that makes the intended relationship easiest to recover.
STUDENT TASK
| Meaning job | Useful forms | Model |
|---|---|---|
| exception / negative condition | unless | We will proceed unless the legal team objects. |
| minimum requirement | provided/providing that; as long as | We can proceed provided that both checks pass. |
| imagined proposal | supposing; assuming | Supposing we shared the cost, would that work? |
| fallback consequence | otherwise; or else | We need approval today; otherwise, we will reschedule. |
| counterfactual cause | but for; without | But for the extra support, the launch would have failed. |
- Match ten situations to the most precise form.
- Write one accurate example for each meaning job.
- Compare the formality of or else and otherwise.
- Explain why unless is unsafe with one already-negative clause.
- Reject one grammatical form because its negotiation effect is wrong.
Finish evidenceSix distinct alternatives with communicative reasons.
Teacher Help · Stage 2
Provided that and as long as can overlap, but tone and context matter. Ask whether the speaker is setting a formal safeguard, reassuring the other side or making permission conditional.
Stage 3 · Control negation, scope and commitment
Check exactly what the condition controls and whose commitment the consequence expresses.
STUDENT TASK
| Control point | Unclear or risky | Controlled |
|---|---|---|
| double negative logic | Unless you don’t object, we will proceed. | Unless you object, we will proceed. |
| scope of requirement | We can change the date provided that the price and delivery stay fixed. | We can change the date, provided that both the price and the delivery schedule remain fixed. |
| speaker commitment | Assuming they agree, it should be possible. | Assuming they agree, we can deliver by Friday. |
| time relationship | But for your help, we fail yesterday. | But for your help, we would have failed yesterday. |
- Rewrite six messages to make scope and commitment explicit.
- Underline the entire phrase controlled by the condition.
- Name the actor responsible for the consequence.
- Check real, imagined and past-counterfactual time.
- Explain how punctuation or clause position supports the reading.
Finish evidenceSix controlled condition–consequence messages.
Teacher Help · Stage 3
Separate grammar accuracy from agreement quality. A sentence can be grammatical yet still hide who must act or what exactly must remain fixed. Ask the learner to restate each side’s obligation in plain language.
Stage 4 · Repair five scope or logic errors
Find the likely business misunderstanding, then repair the smallest unreliable part.
STUDENT TASK
| Problem line | Risk | Repair target |
|---|---|---|
| Unless the payment arrives, we won’t not reserve the room. | stacked negatives reverse or blur the consequence | Unless payment arrives, we will release the room. |
| You can change the order as long as the shipment has left. | condition conflicts with intended deadline | …as long as the shipment has not left. |
| Supposing the supplier agreed, we sign today. | imagined proposal and result form mismatch | Supposing the supplier agreed, could we sign today? |
| Confirm both dates, otherwise one of them may change. | unclear agent and fallback | Name who changes which date. |
| But for the delay, we will finish yesterday. | counterfactual time is impossible | …we would have finished yesterday. |
- Explain the likely misunderstanding in each line.
- Repair logic, scope, time or actor.
- Keep the intended bargaining position stable.
- Check that the result remains fair to both sides.
- Ask a partner to paraphrase the final obligations.
Finish evidenceFive repaired messages with agreement-safe paraphrases.
Teacher Help · Stage 4
Require the partner paraphrase. If two listeners give different obligations, the repair is not finished even if its tense and conjunction are grammatically correct.
Stage 5 · Listen across two accents and clarify consequences
Track what each side offers, requires and will do if a condition fails.
STUDENT TASKBritish English American English
Proposal and fallback
Track the imagined proposal, the clarified consequence and the final agreement.
- Listen once and state the agreement in plain language.
- Listen again and map four conditions and their consequences.
- Identify the alternative used for each relationship.
- Flag two consequences that need clarification.
- Retell each side’s commitments without using the original conjunctions.
Finish evidenceTwo negotiation maps and two clarified consequences.
Teacher Help · Stage 5
The accents test meaning transfer, not imitation. Replay the smallest turn where the learner loses a condition, commitment or fallback, then ask for a plain-language paraphrase.
Stage 6 · Final Practice: negotiate a balanced agreement
Make requirements, flexibility and consequences explicit enough for both sides to accept.
STUDENT TASK
FINAL PRACTICE
Priorities → four conditions → two consequences → check → agreement → retry
- Choose a negotiation: deadline, booking, service plan or project scope.
- Write notes only: must have · flexible point · safeguard · fallback · fair outcome.
- Negotiate four conditions using four distinct alternatives.
- Clarify two consequences by naming actor, action and time.
- Ask your partner to paraphrase each side’s commitments.
- Revise one condition if the paraphrases differ.
- Close with one balanced agreement both sides can repeat.
- After one feedback target, retry only the weakest condition–consequence pair.
Performance rule: A successful alternative makes the relationship clearer; it must not hide a condition or make the other side’s obligation sound stronger than agreed.
Score the first independent performance
MEAN · MeaningRequirement, exception, proposal, fallback and both sides’ commitments remain clear and fair.
FORM · FormThe selected alternatives, negation, tense, scope and consequence structures are accurate.
USE · Real useThe learner negotiates four conditions, clarifies two consequences and closes a balanced agreement.
0 · Not yetA condition reverses, a consequence remains unclear or one side cannot state the agreement.
1 · With supportThe agreement becomes workable after one prompt about form, scope, actor or consequence.
2 · IndependentThe learner varies four alternatives, handles clarification and repairs the weakest condition without a prompt.
Result: 0–2 Rebuild · 3–4 Developing · 5–6 B2 mastery evidence.
Finish evidenceOne balanced agreement + one condition-focused retry.
Teacher Help · Stage 6
Score the first independent attempt across MEAN, FORM and USE. Give one target only: relationship choice, negation, scope, commitment or consequence. Keep the original score and record the retry separately.
Grammar you can use
You can now negotiate conditions without repeating if and keep the resulting commitments clear. Use the Dynamic Learning Graph below to revisit B1 conditional choices, compare past alternatives, continue to formal conditional inversion or review reality-level contrast.
