1) I dared myself to use 'on' instead of 'about' because I've seen this somewhere. Are they both ok?
I'd really like to know the answers to the following two questions. Much obliged if anyone can shed some light, please.
- someone says "I've lived in Paris for seven years." ==> Does he still live in Paris now?
My interpretation: no, because present perfect tense signifies something from the past till the present. He has just finished living in Paris. If he's still living in Paris, he should say, I have been living in Paris for seven years [if he insists on making it clear that he's been there for 7 years]
- This is from a text: "America was now top nation" ==> was + now is certainly confusing
My interpretation: Well, possibly, the narrator or whoever says that was telling a story and to achieve some sort of authenticity? or making the chronological order clear? he's using 'now'. He positions himself with the development of history, as it were, moving forward together as he tells the story/development. Using 'then' --> America was then top nation --> is possible, I guess, when we're standing from the present looking back at the past.
What do the others think?
Very Many Thanks
