Past Simple or Present Perfect?
Choose a clear time viewpoint, ask the right follow-up and repair ambiguous references.
Why this lesson matters · เหตุผลที่เรียนบทนี้
For learners: Choose past simple or present perfect for three common meanings, ask accurate follow-ups, and repair unclear time references.
For teachers: The route separates finished past boundaries from experience and present-result meanings before form practice. Listening, follow-up questions and repair tasks make the tense choice useful in real communication.
สำหรับผู้เรียน: เลือก Past Simple หรือ Present Perfect ให้ตรงกับสามความหมายหลัก ตั้งคำถามต่อเนื่องได้แม่นยำ และแก้การอ้างอิงเวลาที่ไม่ชัดเจน
สำหรับครู: เส้นทางนี้แยกเหตุการณ์อดีตที่จบแล้วออกจากประสบการณ์และผลที่เชื่อมถึงปัจจุบันก่อนฝึกรูปภาษา จากนั้นใช้การฟัง คำถามต่อเนื่อง และการแก้ไขเพื่อให้นำการเลือก tense ไปใช้สื่อสารจริงได้
Your Goal
By the end of this lesson, you can choose past simple or present perfect in three common meanings, ask accurate follow-ups, and repair four unclear time references.

Why this lesson matters
The two tenses can describe related events but organise the listener’s time viewpoint differently. Accurate speakers make a finished boundary or present connection clear and move naturally to specific follow-up questions.
ภาษาไทย: ทั้งสอง tense อาจพูดถึงเหตุการณ์ใกล้เคียงกัน แต่จัดมุมมองเวลาให้ผู้ฟังต่างกัน ผู้พูดจึงต้องทำให้ขอบเขตอดีตหรือความเชื่อมโยงกับปัจจุบันชัด และถามต่อให้ตรงมุมมอง

Teacher Lesson Plan
Start with time meaning and conversation need. Require a finished boundary or present connection before accepting a tense label.
| Stage | Teacher move | Evidence |
|---|---|---|
| 1 · Meaning | Map three time viewpoints. | Nine decisions |
| 2 · Form | Contrast complete frames. | Eight builds |
| 3 · Follow-up | Move between broad and specific reference. | Eight questions |
| 4 · Listen | Recover meaning, form and boundary. | Two maps |
| 5 · Repair | Prioritise unclear references. | Four repairs |
| 6 · Perform | Score MEAN/FORM/USE and retry. | Interview + retry |
Stage 1 · Map three time meanings
Choose what the listener needs to understand before choosing the tense.
STUDENT TASK
| Meaning | Time boundary | Typical message |
|---|---|---|
| finished event at a finished time | closed past period | We completed it last Friday. |
| experience up to now | no finished event time stated | I have visited Chiang Mai three times. |
| past action with present result | current evidence matters | She has finished the report, so we can send it. |
- Classify nine contexts into the three meanings.
- Underline the finished-time boundary or present connection.
- Identify two contexts where both tenses are possible but the message changes.
- Explain the change for the listener.
Finish evidenceNine meaning decisions and two explained viewpoint contrasts.
Teacher Help · Stage 1
Do not teach time words as automatic switches. Require the learner to identify a closed past boundary or a present connection in the whole context.
Stage 2 · Control both verb frames
Build complete statements, negatives, questions and short answers.
STUDENT TASK
| Function | Past Simple | Present Perfect |
|---|---|---|
| affirmative | subject + past form | subject + have/has + past participle |
| negative | did not + base verb | have/has not + past participle |
| question | Did + subject + base? | Have/Has + subject + past participle? |
| short answer | Yes, I did. / No, I didn’t. | Yes, I have. / No, I haven’t. |
- Build four matched tense pairs.
- Change two pairs into negatives.
- Build two questions and short answers for each tense.
- Repair: “Did you ever visited?” and “She has finished it yesterday.”
Finish evidenceEight controlled frames and two explained repairs.
Teacher Help · Stage 2
Keep the same event while contrasting frames. Present Perfect needs a past participle; Past Simple questions use did + base verb.
Stage 3 · Ask the follow-up that fits
Move from broad experience or current result to a specific finished event when the conversation needs detail.
STUDENT TASK
| First message | Accurate follow-up | Tense movement |
|---|---|---|
| I’ve worked with that system. | When did you first use it? | Present Perfect → Past Simple |
| She has completed the review. | What has she found? | present result stays connected |
| We met the supplier last week. | Did they confirm the date? | finished event stays Past Simple |
| Have you ever led a launch? | Which launch did you lead? | experience → specific event |
- Write accurate follow-ups for eight opening messages.
- Mark whether the question keeps or changes the time viewpoint.
- Reject two follow-ups that create an unclear time reference.
- Repair them by adding a clear boundary or present connection.
Finish evidenceEight accurate follow-ups and two time-reference repairs.
Teacher Help · Stage 3
The tense often changes naturally after an experience question when the speaker asks when, where or how a specific event happened.
Stage 4 · Listen for time boundary and present evidence
Recover not only the tense, but why the speaker chose it.
STUDENT TASKAustralian English Indian English
Current result and next question
Listen for present evidence, the completed action and the accurate follow-up.
| Pass | Record | Question |
|---|---|---|
| 1 · Meaning | finished event, experience or result | What does the listener need to know? |
| 2 · Form | complete verb frame | Which tense carries that meaning? |
| 3 · Reference | boundary or present evidence | What makes the choice clear? |
- Listen once and classify the main meaning.
- Listen again and recover six verb frames.
- Record one time boundary and one present-result clue.
- Write one additional accurate follow-up for each clip.
Finish evidenceTwo listening maps, six recovered frames and two new follow-ups.
Teacher Help · Stage 4
Accent variety supports transfer. Do not replay until learners state whether they are listening for a boundary, a present connection or a specific verb frame.
Stage 5 · Repair unclear time references
Make the smallest change that restores a finished boundary or present connection.
STUDENT TASK
| Risk | Unclear version | Repair direction |
|---|---|---|
| finished time + Present Perfect | I’ve called her yesterday. | Past Simple or remove/change the boundary |
| specific-event follow-up stays broad | Have you done it? When have you done it? | When did you do it? |
| no current result | He has left in 2022. | He left in 2022. |
| boundary missing | I worked here. | add finished time or use present connection as intended |
- Diagnose eight unclear messages.
- Select the four with the greatest listener risk.
- Repair each with the smallest safe change.
- Explain whether you restored a past boundary or present connection.
Finish evidenceFour required repairs and four time-reference explanations.
Teacher Help · Stage 5
Require a meaning explanation after each repair. More than one correction may be possible, but the chosen version must create a coherent time viewpoint.
Stage 6 · Final Practice: report, follow up and clarify
Use all three meanings in a connected exchange and repair one deliberate ambiguity.
STUDENT TASK
FINAL PRACTICE
Open with experience → move to a finished event → report a present result → follow up → repair → retry
- Run a 90-second interview about work, study, travel or a completed project.
- Use Present Perfect for one experience and one present result.
- Use Past Simple for one finished event at a clear time.
- Ask at least two accurate follow-up questions that preserve or shift viewpoint appropriately.
- Your partner gives one deliberately unclear time reference; repair it and explain why.
- Receive one target—meaning, form or real use—and retry only the weakest exchange.
Viewpoint model: “I’ve led three training projects. The most recent one started in May, and we finished it last Friday. We’ve received positive feedback, so we’re planning another session. When did you last lead a project?”
Score the first independent performance
MEAN · MeaningThe listener can distinguish finished past time, experience up to now and a present result.
FORM · FormPast Simple and Present Perfect frames, including questions and participles, remain accurate enough.
USE · Real useThe learner asks accurate follow-ups, clarifies one ambiguous reference and maintains a coherent exchange independently.
0 · Not yetAt least one time viewpoint remains unclear to the listener.
1 · With supportThe exchange works after one boundary, form or follow-up prompt.
2 · IndependentAll three meanings, follow-ups and the repair remain coherent without a model.
Result: 0–2 Rebuild · 3–4 Developing · 5–6 B1 performance evidence.
Finish evidenceNine meaning decisions + eight controlled frames + eight follow-ups + two listening maps + four repairs + one connected interview + focused retry.
Teacher Help · Stage 6
Score the first independent exchange. Give one target only and record whether the retry improves time meaning, tense form or conversational follow-up control.
