4. Application in IELTS

In IELTS Speaking:

Using “nod off” can add naturalness to your responses, especially when discussing topics related to sleep, tiredness, or boring situations.

Example question: “Can you describe a time when you felt very tired but had to stay awake?”

Sample answer: “I remember once I had to attend a long business meeting after a night of poor sleep. I was struggling to keep my eyes open and found myself nodding off several times. It was quite embarrassing, but I managed to stay awake by discreetly pinching myself and drinking lots of coffee.”

In IELTS Writing:

While “nod off” is more informal, it can be used effectively in Task 2 essays when discussing sleep-related topics or providing examples.

Example: “Many students find it challenging to maintain focus during lengthy lectures, with some even nodding off due to fatigue or lack of engagement.”
