The verb after the verb is where meaning changes
Here is a small sentence that can expose a large misunderstanding: ‘The team stopped to check the figures.’ It means the team interrupted another activity for the purpose of checking the figures. Now compare it with ‘The team stopped checking the figures.’ This means the checking activity ended. Both sentences are grammatical. They do not tell the same story. A student who replaces every word ending in -ing with ‘to’ and a plain verb will sometimes turn a correct sentence into another correct sentence with the wrong meaning. That is a serious problem in editing because the task is to correct grammatical errors while preserving what the text is saying.
English has several ways to put one verbal idea after another. We may decide to act, avoid acting, look forward to acting, persuade someone to act, let someone act or stop acting. The next form depends partly on the expression before it. Some verbs prefer a to-infinitive, some a gerund, some allow either with little difference, and some change their meaning sharply according to the form. The right strategy is to read a complete clause and ask which relationship the writer intends. Memorising a few labels without understanding the sentence is fragile.
This volume advances from Volume 0289 on adjectives, adverbs and comparison and Volume 0285 on pronoun reference. It also connects to the precise language required in Volume 0292’s cross-subject evidence audit. The canonical job of this guide is verb complementation: which grammatical form is licensed after a particular verb or expression, and how to choose without altering meaning. Earlier guides on tense, clauses, prepositions and sentence structure remain their own lessons. We will use their skills only when they help resolve a verb-pattern decision.
What the actual G3 SEC English examination assesses
The first Singapore-Cambridge Secondary Education Certificate examination takes place in 2027. English Language at G3 is syllabus K300. The official 2027 K300 English Language syllabus states that Paper 1 Writing is 1 hour 50 minutes, carries 70 marks and contributes 35% of the subject assessment. Section A is Editing for 10 marks. Candidates identify and correct grammatical errors in a continuous text of up to 250 words. Spelling and punctuation errors are not tested in this section. The other Paper 1 sections are Situational Writing and Continuous Writing. The official SEAB G3 syllabus index is the reference point for current examination codes and documents.
Paper 2 Reading Comprehension, Paper 3 Listening and Paper 4 Oral Communication have their own tasks and weightings. A well-chosen verb form helps students write and speak clearly across papers, but that does not make this workshop a replica of an official editing passage. Our individual examples isolate one point at a time; actual Paper 1 Editing uses continuous prose with specific instructions. We also distinguish grammatical errors from disagreements about style and from claims that are grammatically acceptable but not factually supported.
What is an infinitive?
In the most useful school-level description, an infinitive is the base form of a verb. A to-infinitive places ‘to’ before that form: to learn, to verify, to explain, to be. It can complete a verb such as decide: ‘We decided to test the calculation.’ It can also express purpose: ‘We paused to test the calculation.’ Those are different relationships. In one, the decision is directed toward an action; in the other, the pause enables an action.
Some expressions instead use a bare infinitive, which is the base form without ‘to’. The modal ‘can’ is followed by the base form: ‘She can explain.’ The causative ‘let’ takes a similar form: ‘The teacher let them explain.’ The mistake ‘can to explain’ is easy to spot, yet the equally wrong ‘let them to explain’ may slip through because ‘persuade them to explain’ is correct. English patterns depend on the governing word, not on a universal rule that all verbs after other verbs need ‘to’.
What is a gerund?
A gerund is a verb form ending in -ing that behaves as a noun-like element in the sentence. In ‘Checking the measurements matters’, the entire phrase ‘Checking the measurements’ acts as the subject. In ‘The group avoided guessing’, ‘guessing’ functions as the complement of ‘avoided’. The -ing form does not by itself tell us that an event is happening right now. It can refer to a general activity, a past experience or an action treated as an idea.
The same visible -ing ending also appears in present participles: ‘The students were checking the measurements.’ That sentence uses the -ing form within a progressive verb phrase. The difference matters when explaining why a construction is correct. It is not necessary to label every -ing word as a gerund before doing any editing. It is enough to recognise how the expression is functioning and whether the words around it require that form.
The governing verb often determines the next form
Consider four patterns. ‘Decide to check’ is natural. ‘Avoid checking’ is natural. ‘Suggest checking’ is natural. ‘Offer to check’ is natural. The student who guesses from the action rather than from the first verb may write ‘avoid to check’ or ‘suggest to check’, both unsuitable in these patterns. You should learn the expressions as pairs: decide to do something, avoid doing something, offer to do something, consider doing something.
Learning a pattern does not mean memorising an enormous table in isolation. Write the verb with a useful example, a contrasting incorrect form and a note about what the pattern lets you say. For instance, ‘recommend inspecting the object’ or ‘recommend that the object be inspected’ can work, whereas ‘recommend to inspect the object’ generally does not mean the same construction. You are learning the frame that carries an intended idea.
A preposition normally takes a noun or an -ing form
Compare ‘The group is interested in learning more’ and ‘The group hopes to learn more’. The first is built around the preposition ‘in’, which takes the activity ‘learning’ as its complement. The second is built around the verb ‘hopes’, which takes a to-infinitive. Copying the surface word ‘to’ is especially dangerous because ‘to’ can be the infinitive marker or a preposition.
‘I look forward to meeting the team’ illustrates a prepositional ‘to’. The phrase ‘look forward to’ is followed by a noun or an -ing form. ‘I look forward to meet the team’ does not fit the intended construction. Similarly, ‘We are committed to improving our work’ uses ‘to’ as a preposition. Compare that with ‘We intend to improve our work’, where ‘to improve’ is an infinitive. Read the entire expression, not just the word immediately before the gap.
Objects are part of the verb pattern
Some verbs need an object before their infinitive. ‘We persuaded her to explain the figures’ has an object ‘her’ and a to-infinitive ‘to explain’. ‘We allowed the visitors to enter’ follows another object-plus-infinitive pattern. A student may repair the verb form but omit the object, changing the structure or the intended agent. That is why editing cannot be done by looking at the underlined word alone.
Other verbs form a different pattern. ‘Let her explain’ and ‘made her explain’ use a bare infinitive in the active voice. But ‘She was made to explain’ requires the ‘to’ after a passive form of ‘make’. These structures are similar in meaning but not interchangeable in form. Read whether the clause is active or passive before applying a rule.
The change of meaning is the examination-level challenge
‘Remember to submit the report’ means do not forget a future or required action. ‘Remember submitting the report’ refers to the memory of an action already experienced. ‘Stop to read the notice’ means pause another activity to read; ‘stop reading the notice’ means cease the reading. ‘Try to open the file’ presents an attempt; ‘try opening the file’ presents an experimental suggestion as one possible solution. These are not mechanical pairs to be exchanged for variety.
The reader must ask what the story says happened. Did the team cease checking? Did they pause to check? Was the instruction about a future duty or a memory of something completed? A grammatical choice can alter the timeline, responsibility or action. Accurate editing protects all three.
The difference between a grammar repair and a factual correction
Imagine a fictional display announcement: ‘The coating prevents rust forever.’ The grammar is sound, but the universal factual claim is not established by a short observation. Changing ‘prevents’ to ‘preventing’ would create a grammatical problem without fixing the evidence problem. The correct learning response is to recognise the distinction. In K300 Editing, work on the grammatical errors required by the passage. In a writing or science-based task, you may also need to calibrate the claim to the available evidence.
A useful habit is to make two separate checks. Grammar asks whether the words fit their sentence functions and constructions. Evidence asks whether the statement is warranted. Volume 0292 models that discipline across English, Mathematics and Science. This guide will stay with the verb-form side of the problem, even when our practice sentences use measurement, school reports and scientific examples.
Learn the contrast, not a magic replacement rule
The most reliable method is to identify the governing expression, locate any required object, decide whether ‘to’ is a marker or a preposition and compare the meaning of any alternative. Some pairs are both possible: ‘begin reading’ and ‘begin to read’ can be acceptable in ordinary contexts. ‘Help check’ and ‘help to check’ can also both be acceptable. If both forms are grammatical and appropriate, an editor should not invent an error merely because one sounds more familiar.
A genuine error has a reason. ‘We avoided to guess’ is unacceptable in the intended pattern because ‘avoid’ normally takes an -ing complement. ‘We stopped to guess’ may be grammatical but says that guessing was the purpose of stopping. The question is not whether the sentence could exist in some imagined story; it is whether it expresses the meaning the surrounding text requires.
An efficient four-question test
Ask yourself: What is the governing verb or expression? Does it need an -ing form, to-infinitive, bare infinitive or an object-plus-verb pattern? If both forms are possible, does changing them change the meaning? Finally, does the choice preserve the timing and agent that the paragraph describes? These questions are short enough to run inside a timed paper and strong enough to catch errors that a vague ‘sounds correct’ check may miss.
The twenty-eight original decisions below become steadily more demanding. Some target a fixed frame, some a preposition, some an object, and some a meaning contrast. A small number deliberately contain no error. That matters: in a real editing task you should correct an error, not decorate a correct sentence with an unnecessary replacement.
Twenty-eight original worked editing decisions
1. Decide
Sentence to inspect: Sentence: ‘The committee decided revising the notice before publication.’
Reasoned answer: The standard intended pattern is ‘decided to revise the notice’. ‘Decide’ takes a to-infinitive when it introduces the chosen action. The original gerund does not fit that complement pattern.
Exam transfer: Check what the committee chose to do. The decision precedes the action; the form is about the governing verb, not about the action being ongoing.
2. Avoid
Sentence to inspect: Sentence: ‘The student avoided to guess the missing number.’
Reasoned answer: Use ‘avoided guessing the missing number’. ‘Avoid’ is normally followed by a noun or gerund, not a to-infinitive. The change repairs the complement without changing the point.
Exam transfer: Do not convert ‘avoided’ into ‘decided’ merely to save ‘to guess’; that would reverse the student’s behaviour.
3. Offer
Sentence to inspect: Sentence: ‘She offered checking the figures again.’
Reasoned answer: Use ‘offered to check the figures again’. ‘Offer’ followed by an action generally takes a to-infinitive. The action is proposed or volunteered rather than described as an enjoyed activity.
Exam transfer: A small form change can clarify who has volunteered to perform the work.
4. Consider
Sentence to inspect: Sentence: ‘They considered to move the panel nearer the entrance.’
Reasoned answer: Use ‘considered moving the panel’. ‘Consider’ takes an -ing complement when introducing a possible action. This is a deliberation, not a firm decision to move it.
Exam transfer: Compare ‘decided to move’ and ‘considered moving’: the verbs convey different degrees of commitment.
5. Suggest
Sentence to inspect: Sentence: ‘The teacher suggested to compare both samples.’
Reasoned answer: Use ‘suggested comparing both samples’ or ‘suggested that we compare both samples’, according to the intended subject. ‘Suggest’ does not take the simple ‘suggest to compare’ pattern in this use.
Exam transfer: The ‘that’-clause alternative must retain the intended actor. Grammar repairs should not invent one silently.
6. Enjoy
Sentence to inspect: Sentence: ‘The class enjoyed to visit the science exhibition.’
Reasoned answer: Use ‘enjoyed visiting the science exhibition’. ‘Enjoy’ is conventionally followed by a noun or an -ing form. This makes the activity what the students enjoyed.
Exam transfer: Do not confuse this past-tense verb with the separate concept of a continuous tense; the gerund names the enjoyed activity.
7. Hope
Sentence to inspect: Sentence: ‘I hope meeting the principal next week.’
Reasoned answer: Use ‘I hope to meet the principal next week’. The regular intended construction is ‘hope to do something’, with a future-oriented wish or expectation.
Exam transfer: ‘Hope of meeting’ is another construction in some contexts, but it is not the repair for the particular sentence given.
8. Postpone
Sentence to inspect: Sentence: ‘The organisers postponed to announce the results.’
Reasoned answer: Use ‘postponed announcing the results’. ‘Postpone’ takes a noun or gerund to name the action delayed. The announcement is delayed; it is not necessarily cancelled.
Exam transfer: Changing ‘postponed’ to ‘refused’ would alter the event and should not be done in an editing task.
9. A preposition: interested in
Sentence to inspect: Sentence: ‘The students were interested in learn more about the method.’
Reasoned answer: Use ‘interested in learning more’. After the preposition ‘in’, the gerund supplies a noun-like activity. A bare verb does not complete this construction.
Exam transfer: Locate the preposition before deciding how to repair the following verb.
10. Look forward to
Sentence to inspect: Sentence: ‘I look forward to receive your reply.’
Reasoned answer: Use ‘I look forward to receiving your reply’. The ‘to’ in ‘look forward to’ functions as a preposition, so the following action takes an -ing form.
Exam transfer: Do not rely on the rule ‘every to is followed by a base verb’. This is the classic exception because the grammatical role of ‘to’ differs.
11. Committed to
Sentence to inspect: Sentence: ‘The group is committed to complete the audit accurately.’
Reasoned answer: Use ‘committed to completing the audit accurately’. In this expression ‘to’ is a preposition followed by a gerund. Another correct construction is ‘intends to complete’, but that changes the choice of main expression.
Exam transfer: The editing aim is a minimal repair that keeps the original claim of commitment.
12. Before a gerund
Sentence to inspect: Sentence: ‘Before to submit the report, the leader checked the tables.’
Reasoned answer: Use ‘Before submitting the report, the leader checked the tables.’ Here ‘before’ functions as a preposition introducing a non-finite clause with an -ing verb. ‘Before she submitted…’ is also possible but changes the structure more.
Exam transfer: The original sentence says the checking preceded submission. Preserve that chronology.
13. Persuade and an object
Sentence to inspect: Sentence: ‘They persuaded their teammate checking the arithmetic.’
Reasoned answer: Use ‘persuaded their teammate to check the arithmetic’. The person persuaded is the object, followed by a to-infinitive naming the intended action.
Exam transfer: ‘Persuaded to check’ may leave the actor unclear; preserve the person specified by the text.
14. Allow someone to
Sentence to inspect: Sentence: ‘The organiser allowed the visitors enter in small groups.’
Reasoned answer: Use ‘allowed the visitors to enter in small groups’. In the intended active construction, ‘allow + object + to-infinitive’ is standard.
Exam transfer: The missing ‘to’ is a grammatical issue; it does not itself tell us whether the group-size restriction was sensible.
15. Let someone do
Sentence to inspect: Sentence: ‘The teacher let the learners to explain their answers.’
Reasoned answer: Use ‘let the learners explain their answers’. ‘Let + object + bare infinitive’ is the pattern. The extra ‘to’ is incorrect here.
Exam transfer: Compare this with ‘allowed the learners to explain’. Similar meaning does not imply identical grammar.
16. Make someone do
Sentence to inspect: Sentence: ‘The supervisor made the team to recheck the numbers.’
Reasoned answer: Use ‘made the team recheck the numbers’. Active causative ‘make + object + bare infinitive’ expresses a compelled action.
Exam transfer: Do not mistake the correction for a judgment about the supervisor’s decision; only the complement is in question.
17. Passive make
Sentence to inspect: Sentence: ‘The team was made recheck the numbers.’
Reasoned answer: Use ‘The team was made to recheck the numbers’. The passive form of causative ‘make’ normally requires ‘to’ before the infinitive.
Exam transfer: Compare the active ‘The supervisor made the team recheck’. Voice changes the form of the complement.
18. Modals
Sentence to inspect: Sentence: ‘Students should to verify every calculation.’
Reasoned answer: Use ‘Students should verify every calculation’. A modal such as should takes the bare infinitive, not ‘to’ plus infinitive.
Exam transfer: Also remember ‘can check’ and ‘must check’. Do not apply the ‘decide to’ pattern to modal auxiliaries.
19. The help option
Sentence to inspect: Sentence: ‘The team helped to prepare the display.’ Is this an error?
Reasoned answer: No. Both ‘helped prepare the display’ and ‘helped to prepare the display’ are grammatical in ordinary usage. The existing form need not be changed.
Exam transfer: A good editor knows when to leave a sentence alone. Preference is not proof of an error.
20. Begin is flexible
Sentence to inspect: Sentence: ‘The students began reading the instructions.’ Is a correction needed?
Reasoned answer: No. ‘Began reading’ is grammatical, and ‘began to read’ is also possible in many contexts. The two forms often have little difference in basic meaning here.
Exam transfer: An editing task is not a competition to replace every familiar -ing construction.
21. Stop to check
Sentence to inspect: A report says, ‘The walkers stopped to check the route.’ What happened?
Reasoned answer: They interrupted another activity in order to check the route. Here the infinitive describes the purpose of stopping. It does not mean they stopped checking the route.
Exam transfer: Keep this meaning intact if a surrounding story describes an inspection begun at that pause.
22. Stop checking
Sentence to inspect: A report says, ‘The walkers stopped checking the route.’ What happened?
Reasoned answer: They ceased the checking activity. The gerund names the activity that ended. It is a different event from pausing to start a check.
Exam transfer: Both sentences may be grammatically correct. Context, not an automatic suffix rule, determines which reports the intended action.
23. Remember to submit
Sentence to inspect: Sentence: ‘Please remember submitting the form tomorrow.’
Reasoned answer: The natural intended instruction is ‘Please remember to submit the form tomorrow’. The to-infinitive refers to a duty that still needs to be performed.
Exam transfer: The word ‘tomorrow’ helps establish the intended forward-looking meaning.
24. Remember submitting
Sentence to inspect: Sentence: ‘I remember submitting the form last Friday.’ Is the verb form wrong?
Reasoned answer: No. ‘Remember submitting’ refers to a memory of an earlier action. The time expression ‘last Friday’ supports that reading. Changing it to ‘remember to submit’ would shift the time and meaning.
Exam transfer: Look for the timing clues before deciding whether there is an error.
25. Forget to lock
Sentence to inspect: Sentence: ‘He forgot locking the cabinet, so it remained open all evening.’
Reasoned answer: If the intended story is that he failed to lock it, use ‘forgot to lock the cabinet’. ‘Forgot locking’ would normally suggest failure to remember a completed act of locking.
Exam transfer: A grammatical repair can restore the intended event, but it must be guided by the context.
26. Try to open versus try opening
Sentence to inspect: Compare ‘She tried to open the file’ with ‘She tried opening the file’.
Reasoned answer: The first presents an attempt to achieve the action. The second often presents opening it as an experiment or proposed solution among possible methods. Both are grammatical in fitting contexts.
Exam transfer: Do not replace one with the other simply for variety; determine whether the writing describes an attempt or a suggested approach.
27. Regret to inform versus regret saying
Sentence to inspect: Compare ‘We regret to inform you that the event is cancelled’ and ‘I regret saying that the event was cancelled.’
Reasoned answer: ‘Regret to inform’ is a conventional formal way to introduce unwelcome news being communicated now. ‘Regret saying’ expresses remorse about a previous act of speaking. Different complements create different time relationships.
Exam transfer: A writer may intend either, but an editor must preserve the original communicative purpose.
28. Gerund subject
Sentence to inspect: Sentence: ‘Checking the measurements are important.’
Reasoned answer: Use ‘Checking the measurements is important’. The complete gerund phrase functions as one subject activity and normally takes a singular verb. The plural ‘measurements’ inside it is not the grammatical head of the subject.
Exam transfer: This case integrates verb complementation with agreement. Identify the full subject before choosing the finite verb.
Test the logic with a miniature continuous passage
Read this original practice passage without correcting anything yet: ‘Our class decided checking the information board before the school visit. We hoped to remove confusing statements and considered to replace one diagram. We looked forward to meet the volunteers who would help us. The teacher let us to review the display, but we stopped to reviewing it when the bell rang.’ Five expressions demand inspection, and the precise repairs follow their governing patterns.
First, ‘decided checking’ becomes ‘decided to check’. Second, ‘considered to replace’ becomes ‘considered replacing’. Third, ‘looked forward to meet’ becomes ‘looked forward to meeting’, because ‘to’ is a preposition in that expression. Fourth, ‘let us to review’ becomes ‘let us review’. Fifth, assuming the bell caused the reviewing to cease, ‘stopped to reviewing’ becomes ‘stopped reviewing’. A useful editor can explain each change rather than relying on a guessed rhythm.
Now consider a different sentence from the same fictional report: ‘We stopped to review the display when the visitors arrived.’ That might be perfectly grammatical if the students were doing something else, paused and began the review. It would be wrong to change it automatically to ‘stopped reviewing’. The words around the form determine the event. Meaning is the restraint that keeps grammar editing from becoming random substitution.
Why isolated examples are only the first stage
A real editing passage is continuous. The candidate must track who is doing what, whether an event has already happened and how one sentence fits the next. An isolated sentence may permit two reasonable interpretations. A paragraph may rule one out. For instance, ‘We remembered meeting her’ and ‘We remembered to meet her’ can each work in separate stories, but a narrative about an appointment that still had to occur strongly favours the second meaning.
Build a short paragraph of 120 to 180 words around a familiar school event and use several different complement patterns. Then reread it without highlighting anything. Mark only constructions for which you can give a concrete reason. This trains the visual search skill required in a continuous-text task, instead of encouraging a student to treat every ‘to’ or ‘-ing’ as suspicious.
Create your own pattern notebook
A useful notebook need not be long. Make four columns headed expression, required form, clear example and common trap. Under to-infinitive, include decide to, offer to, hope to and manage to. Under gerund, include avoid doing, enjoy doing, consider doing and postpone doing. Under preposition-plus-gerund, include interested in doing, look forward to doing and committed to doing. Under object patterns, include persuade someone to do, allow someone to do, let someone do and make someone do.
Put meaning-changing pairs on a separate page: stop to versus stop -ing; remember to versus remember -ing; forget to versus forget -ing; try to versus try -ing. These deserve examples with a timeline, not just one-word labels. Two sentences that are both grammatical but report different events cannot be treated as alternative spellings of one idea.
Repair one error category at a time
When a student makes an error, identify the category before giving another page of practice. Was the governing verb misremembered? Was the prepositional ‘to’ mistaken for an infinitive marker? Did the student leave out an object? Was a bare infinitive incorrectly given ‘to’? Did an active-to-passive change alter the pattern? Or was the sentence already correct, and the student introduced an unnecessary edit?
A category tells you what to practise. If the difficulty is after a preposition, train the contrast between ‘look forward to meeting’ and ‘intend to meet’. If it is a passive causative, train ‘made them check’ versus ‘they were made to check’. If meaning is changing, rehearse a two-event timeline. Recognising a reason is more useful than repeatedly copying a corrected model answer.
The five-day route from recognition to performance
On day one, complete Decisions 1–8 and write a one-line governing-pattern rule for each. On day two, complete Decisions 9–18, paying special attention to prepositions, required objects and active versus passive constructions. On day three, complete Decisions 19–27 and explain why some sentences need no repair or change their meaning when altered. On day four, complete Decision 28 and the miniature continuous passage, then write your own original paragraph with six different patterns. On day five, set a timed editing exercise using an unfamiliar continuous text and review only the grammatical corrections you can justify.
The reflection should be specific. Avoid saying ‘I am weak at grammar’. Write ‘I treated the preposition in look forward to as an infinitive marker’ or ‘I forgot that let takes a bare infinitive’. The next practice can then target a recognisable structure. If a sentence is acceptable, practise explaining why no edit is needed. Good judgment means correcting mistakes and respecting correct prose.
From sentence accuracy to examination communication
A candidate writing an English report or proposal needs these patterns because they encode decisions and responsibilities: ‘recommend checking’ states an action proposed; ‘decided to check’ says a decision was made; ‘stopped checking’ says the activity ended. Confusing them can change the reported sequence of events. This is why accuracy is not merely a matter of tidy presentation.
Yet there is no reward in overcomplicating ordinary writing. Clear sentences with familiar verbs often serve the reader best. If a sentence can say ‘We checked the figures’, do not force a complex complement merely to sound advanced. English examination performance depends on fulfilling the actual task and communicating accurately, not on using every construction in a grammar book.
