Lesson 12

Gerunds vs Infinitives: Meaning Changes After Stop, Remember, Try and Regret

This lesson groups five rules that students commonly confuse because they look similar on the surface. Treat the first verb or preposition as a pattern trigger. Work through the examples slowly once; speed comes after the pattern is clear.

What you will learn

  • Understand and apply: 'Stop doing' differs from 'stop to do'.
  • Understand and apply: 'Remember doing' differs from 'remember to do'.
  • Understand and apply: 'Try doing' differs from 'try to do'.
  • Understand and apply: 'Regret doing' differs from 'regret to inform'.
  • Understand and apply: 'Need doing' can mean 'need to be done'.

For every rule: spot the trigger → identify the grammatical relationship → apply the form → check meaning.

Before you start

Try the warm-up without checking the rule. The purpose is to expose the instinct you currently use, not to score marks.

Which sentence follows the target grammar pattern?

A. He stopped checking his phone during study sessions.

B. He stopped to checking his phone during study sessions.

Answer: A. Stop doing means end an activity; stop to do means pause one activity in order to perform another.

Rule 1 · G056

'Stop doing' differs from 'stop to do'

Stop doing means end an activity; stop to do means pause one activity in order to perform another.

Correct example

He stopped checking his phone during study sessions.

Incorrect example

He stopped to checking his phone during study sessions.

Interpretation

Stop doing means end an activity; stop to do means pause one activity in order to perform another. In a test, do not memorise this as an isolated sentence. Treat the first verb or preposition as a pattern trigger. The correct example shows the pattern in context; compare it directly with the incorrect version and identify the exact word that must change.

Why it matters

Gerund/infinitive choices often look arbitrary unless students learn the trigger and the change in meaning.

Common exam trap

Choosing between -ing and to + verb by meaning alone when the first verb actually controls the pattern.

How to spot it

Look immediately before the second verb. A preposition or a pattern-trigger verb usually decides between -ing and to + verb.

3-step solving method

  1. Look at the word before the second verb.
  2. Recall whether that trigger takes -ing, to + verb, or changes meaning.
  3. Read the full sentence to confirm the intended meaning.

Why the incorrect example fails

The target structure requires this rule: Stop doing means end an activity; stop to do means pause one activity in order to perform another. In the incorrect version, the repair is to remove “to”. That is the exact edit a student should be able to justify in an error-spotting question.

Nuance and memory hook

Verb-complement patterns are partly lexical. Learn high-frequency combinations rather than trying to invent one universal rule.

Stop doing = end it; stop to do = pause for another purpose.

Quick check

Without relying on what 'sounds right', explain which part of this sentence violates the rule: “He stopped to checking his phone during study sessions.”

Reveal quick check answer

Apply 'Stop doing' differs from 'stop to do': Stop doing means end an activity; stop to do means pause one activity in order to perform another.

Practice questions

Apply the rule in context

Which sentence is the better choice in standard exam-oriented English?

Explain the error rather than guessing by sound

Why is this sentence problematic in the target rule? “He stopped to checking his phone during study sessions.”

Rule 2 · G057

'Remember doing' differs from 'remember to do'

Remember doing recalls a past action; remember to do means not forgetting a required action.

Correct example

Remember to submit the form before midnight.

Incorrect example

Remember submitting the form before midnight if you have not done it yet.

Interpretation

Remember doing recalls a past action; remember to do means not forgetting a required action. In a test, do not memorise this as an isolated sentence. Treat the first verb or preposition as a pattern trigger. The correct example shows the pattern in context; compare it directly with the incorrect version and identify the exact word that must change.

Why the incorrect example fails

The target structure requires this rule: Remember doing recalls a past action; remember to do means not forgetting a required action. In the incorrect version, the repair is to replace “submitting” with “to submit”; replace “midnight if you have not done it yet.” with “midnight.”. That is the exact edit a student should be able to justify in an error-spotting question.

Nuance and memory hook

Verb-complement patterns are partly lexical. Learn high-frequency combinations rather than trying to invent one universal rule.

Remember doing = memory; remember to do = duty.

Without relying on what 'sounds right', explain which part of this sentence violates the rule: “Remember submitting the form before midnight if you have not done it yet.”

Rule 3 · G058

'Try doing' differs from 'try to do'

Try doing means experiment with a method; try to do means make an effort to accomplish something.

Correct example

If the passage feels dense, try reading the first sentence of each paragraph again.

Incorrect example

If the passage feels dense, try to reading the first sentence of each paragraph again.

Interpretation

Try doing means experiment with a method; try to do means make an effort to accomplish something. In a test, do not memorise this as an isolated sentence.

Rule 4 · G059

'Regret doing' differs from 'regret to inform'

Regret doing looks back unhappily on an action; regret to say/inform is a formal way to introduce bad news.

Correct example

I regret wasting so much time on one question.

Incorrect example

I regret to wasting so much time on one question.

Interpretation

Regret doing looks back unhappily on an action; regret to say/inform is a formal way to introduce bad news. In a test, do not memorise this as an isolated sentence.
