Stop Doing vs Stop To Do: End One Activity or Pause for Another
Follow the timeline. Ask whether the action after stop ended, or whether someone paused one activity in order to begin another.
One activity pauses and a different activity begins = stop to do
Choose doing
The activity after stop finished, was discontinued, was replaced, was prohibited or will no longer continue.
Choose to do
Someone paused a journey, task, meeting or inspection and began another action before continuing or returning.
Use the timeline signal
Do not translate both choices slowly. Find the later words that show whether the action ended or began during a pause.
The company stopped ___ printed invoices after online billing began.
Answer: sendingPrinted invoices ended when the replacement system began.
The manager stopped ___ an urgent call before continuing.
Answer: to answerAnother activity paused, and answering the call began.
The answer words change with the action: sending / to send, checking / to check, helping / to help. The decision does not change: activity ends, or another activity begins after a pause.
What your result reveals
Your score shows whether you followed the timeline: the activity after stop ended, or one activity paused and another began. Use the Review to locate the exact timeline signal before checking the answer form.
If doing caused problems
Review sentences with replacement systems, new policies, prohibitions, closing dates, permanent changes or activities that no longer continue.
If to do caused problems
Review sentences with journeys, meetings, inspections or tasks that pause so someone can answer, check, help, inspect or clarify something.
If stop automatically meant finish
Do not assume the next action always ended. Look for continuation, return, resumption, movement or an urgent new action.
Use the Review in this order: check the correct answer, locate the exact timeline signal, decide whether the next activity ended or began during a pause, then confirm the reusable pattern. Do not translate both choices before finding the timeline.
