On my last lesson I had a discussion with my teacher about the sentence described below. The reason was that on my grammar reference in one of my books is written that past perfect continuos can be used to emphasize on the continuity, duration and repeated activities.
We received one sentence and according with the above my answer was Maise had been eating
Maise ate / had been eating sweets all evening so it was not suprising she didn't want any supper.
Unfortunately my teacher said that the correct answers is Maise ate
Can I ask you why ?
