THE IDEA, SIMPLY

The rule, with an example

Stop doing means end that activity. Stop to do means pause something else in order to do it. Remember doing recalls a past event; remember to do concerns a task you must not forget.

SEE IT IN CONTEXTI stopped checking my phone. I stopped to check my phone. These describe different actions.
Skills to work on in this practice
  • Notice changes in meaning
  • Distinguish remembering and forgetting actions
  • Choose the pattern that matches the situation

Compare the meaning, not just the form

UseExampleWhy it works
An activity endsShe stopped talking.The talking ended.
A pause for a purposeShe stopped to talk.She paused another activity in order to talk.
Memory or taskI remember locking it. / Remember to lock it.The first recalls a past action; the second gives a reminder.

Common mistake

Check: Treating remember doing and remember to do as identical

Use: Check whether the action is a memory or a task

The verb pattern changes the time relationship and the message.

How should I practise this?

Read the example and explain the choice before answering. After the exercise, write a new sentence using the same pattern. Revisit any answer you could not explain, even if you guessed correctly.
