New English 'teacher' in Poland (I have no qualifications). [119]
Still, I had no idea what the past perfect was when I stepped into the classroom to work for NOVA. Natives just don't know the labels.
Another point is, the AmE Vs BrE dimension. I reckon I know AmE pretty well, having watched a lot of American TV and spent time with Americans. They almost never use perfect tenses, especially the past perfect. Even in large parts of Britain, it is redundant. It just shows the more elastic nature of time/the relationship between two past actions.
For example, I wouldn't even have known to teach things like, 'I didn't eat yet'. In school, I'd've felt that to have been wrong. Still, as my exposure increased, I came to see that it was used widely. Brits would say, 'I haven't eaten yet' instead. There have been quite a few occasions in class where I was thinking, how on earth would my friend teach this when he doesn't even use it? One could easily argue that Americans have to fight that bit harder to get to grips with the labels.
