In a sentence like the one below, is the present perfect acceptable?
This past week I have learned all sorts of things.
Would it make more sense to say:
The past week I learned all sorts of things
if it's implied by "past" that my learning of all sorts of things was completed last week? However, the "this" before "past week," to me, makes it seem like the week is still ongoing?
Some additional questions: Is there a difference between these sentences in meaning? Does either sound better than the other?
