While he ………… his young brother, he felt something wrong in his speech.
- was hearing
- is hearing
This sentence was discussed in an Egyptian Facebook group for English Teachers. Their opinions were like that:
- Some answered (heard)
- Some answered (was hearing)
Those who answered (heard) justify their answer that (hear) cannot be in progressive.
But the second group provided a proof:
- I thought I was hearing things. (Longman Grammar of Spoken and Written English)
- That was the music that I was hearing every day.
- Others said that the answer should be (was listening).
What about you?
