Why this lesson matters
Dependent prepositions belong to complete lexical combinations. A wrong or missing link can make cause, responsibility, impact or solution sound unnatural—or reverse the intended relationship.

Teacher Lesson Plan
Teach head, preposition, complement and meaning as one retrievable chunk. Evaluate the logical relationship after every form repair.
| Stage | Teacher move | Evidence |
|---|---|---|
| 1 · Retrieve | Build twelve complete chunks. | Twelve contexts |
| 2 · Type | Sort verb/adjective/noun combinations. | Three types |
| 3 · Repair | Restore form and relationship. | Five repairs |
| 4 · Listen | Recover head, link and logic. | Two maps |
| 5 · Plan | Map problem to solution. | Eight-chunk plan |
| 6 · Perform | Score MEAN/FORM/USE and retry. | Briefing + retry |
Stage 1 · Retrieve twelve complete combinations
Learn the head word, dependent preposition and meaning as one usable chunk.
STUDENT TASK
| Verb + preposition | Adjective + preposition | Noun + preposition |
|---|---|---|
| depend on | responsible for | reason for |
| deal with | aware of | solution to |
| result in / result from | concerned about | increase in |
| contribute to / respond to | capable of | impact on |
- Cover the prepositions and retrieve all twelve high-value combinations.
- Match each chunk to a workplace problem or solution meaning.
- Build one short context for every chunk.
- Mark four combinations whose preposition differs from a likely Thai-to-English translation guess.
Finish evidenceTwelve retrieved chunks and twelve contextual examples.
Teacher Help · Stage 1
Retrieval must include the head word, preposition and meaning. Do not teach the preposition as an independent rule that applies to every synonym.
Stage 2 · Distinguish three chunk types and complements
Use the grammatical type to build the words before and after the preposition accurately.
STUDENT TASK
| Chunk type | Frame | Example complement |
|---|---|---|
| verb + preposition | subject + verb + prep + noun/-ing | respond to feedback · depend on receiving data |
| adjective + preposition | be/seem + adjective + prep + noun/-ing | responsible for checking records |
| noun + preposition | determiner + noun + prep + noun/-ing | a solution to the delay |
| contrast pair | result in = cause an outcome | result from = be caused by a source |
- Sort twelve chunks into verb, adjective and noun types.
- Build two noun complements and two -ing complements per type.
- Contrast result in with result from in two linked sentences.
- Explain why “to” in contribute to is a preposition before verb-ing.
Finish evidenceTwelve type labels, twelve complements and one cause/result contrast.
Teacher Help · Stage 2
After a dependent preposition, use a noun phrase or verb-ing, not an infinitive. Make the head-word type visible so learners can build the surrounding clause.
Stage 3 · Repair five high-risk preposition errors
Restore the complete chunk and check that the repaired meaning still fits the problem–solution relationship.
STUDENT TASK
| Risk | Error pattern | Repair question |
|---|---|---|
| wrong preposition | depend of the schedule | What is the stored chunk? |
| missing preposition | respond the complaint | Does the head require a link? |
| infinitive after preposition | responsible for to check | Noun or verb-ing after prep? |
| cause direction reversed | result from a delay when meaning cause | Source or outcome? |
| wrong head family | a solution for the problem in target chunk | Which formal chunk fits here? |
- Audit ten problem-and-solution sentences.
- Select the five with highest meaning or naturalness risk.
- Repair each with the smallest safe change.
- State the chunk type and meaning after every repair.
Check the whole chunk
Repair the head word, preposition and complement together. A locally correct preposition can still produce the wrong cause direction or an unnatural combination.
Finish evidenceFive required repairs and five chunk-type explanations.
Teacher Help · Stage 3
Require full-chunk evidence. Some varieties permit alternatives in some contexts; accept them only when reliable reference evidence supports the intended register and meaning.
Stage 4 · Listen for problem, link and solution
Recover the dependent chunk and the logical relationship it builds.
STUDENT TASKBritish English · Brian American English · Joanna
Present the solution
Listen for noun combinations, responsibility and one repaired error.
| Pass | Record | Question |
|---|---|---|
| 1 · Head | verb, adjective or noun | What word controls the chunk? |
| 2 · Link | preposition + complement | What completes the relationship? |
| 3 · Logic | source, effect, responsibility or solution | What does the chunk mean here? |
- Listen once and map problem → cause → impact → solution.
- Listen again and recover ten complete combinations.
- Label the three chunk types.
- Retell four relationships with different but accurate target chunks.
Finish evidenceTwo listening maps, ten recovered chunks and four accurate reformulations.
Teacher Help · Stage 4
Accent variety supports chunk recognition. Replay the whole clause so learners hear the head–preposition–complement unit and its logical role.
Stage 5 · Plan a problem-and-solution briefing
Choose chunks that make cause, responsibility, impact and action relationships explicit.
STUDENT TASK
| Briefing move | Required note | Target combinations |
|---|---|---|
| problem | observable issue | concerned about · reason for |
| cause | source and contributing factor | result from · contribute to |
| impact | effect on people/process | result in · impact on |
| responsibility | owner and capability | responsible for · capable of |
| solution | response and dependency | solution to · respond to · depend on |
- Choose a real or realistic work, study or community problem.
- Plan at least eight target combinations across all three types.
- Make source, impact, responsibility and solution explicit.
- Prepare one clarification question and one chunk repair.
Finish evidenceAn eight-chunk briefing map with all three types and one repair plan.
Teacher Help · Stage 5
Avoid dense chunk display. Each combination must add a needed logical relationship and remain interpretable to the listener.
Stage 6 · Final Practice: diagnose, solve and repair
Use dependent combinations to make a concise problem–solution chain, not a vocabulary list.
STUDENT TASK
FINAL PRACTICE
State problem → trace cause → show impact → assign responsibility → propose solution → retry
- Deliver a 90-second problem-and-solution briefing.
- Use at least eight of the twelve target combinations.
- Include verb, adjective and noun chunk types.
- Your partner asks one source, responsibility or solution clarification.
- Repair one deliberately incorrect preposition and explain the chunk type.
- Receive one target—meaning, form or real use—and retry only the highest-risk section.
Briefing model: “The delay resulted from incomplete handover notes and contributed to an increase in repeat calls. The service team is responsible for responding to urgent cases, but the long-term solution to the problem depends on improving the shared record.”
Score the first independent performance
MEAN · MeaningThe listener can follow source, impact, responsibility and solution relationships without chunk ambiguity.
FORM · FormHead word, dependent preposition, complement and three chunk types remain accurate enough.
USE · Real useThe learner delivers a usable briefing, answers clarification and repairs a preposition error independently.
0 · Not yetAt least one high-impact relationship remains false or unclear.
1 · With supportThe briefing works after one chunk, complement or logic prompt.
2 · IndependentEight chunks, all three types and the repair remain clear without a model.
Result: 0–2 Rebuild · 3–4 Developing · 5–6 B2 performance evidence.
Finish evidenceTwelve retrieved combinations + three chunk types + five repairs + two listening maps + one problem–solution briefing + focused retry.
Teacher Help · Stage 6
Score the first independent briefing by relationship risk. Give one target only and record whether the retry improves chunk meaning, form or problem–solution logic.
