Besides, we use Simple Past with last week. Do you know what tense we use with for the last week? Yes, we usually use Present Perfect wiht the for the last week. |
This topic has its funny sides. Students do get confused with the Perfect tenses (generally, they don't have any problem with the Continuous tenses). The reasons perhaps are:
1. Some grammarians and linguists do split hairs, others may have time on their hands, yet others may prefer to publish on "new frontiers".
2. The "incompatibility" with adverbials that denote a SPAN of time (e.g. for the past few weeks) arises, IMO, from saying that the Perfect tense indicates COMPLETION. The idea of a "completed" action sticks in the mind, and learners find it hard to reconcile this with a sentence like "I have lived in Shenyang for the past two years", or "He has been teaching French since 1984", because both are not "completed" actions but go on still.
3. "Last week" is a point of time in the past, so no problem here. "For the past week" is a span of time that goes on still, so is considered incompatible with the idea of "completed" action.
4. I define the Present Perfect tense as expressing an action that is already COMPLETED at the present time, OR an action BEGUN earlier and spanning a period to the present time. I gave this opinion in another thread on this site, talking about the Perfect Participle. IMHO, this participle expresses the aspects BEGUN and/or COMPLETED.
Sometimes (not always and always, though), I think we can/should take language less seriously so it is more fun and easier to learn. Like this couplet I posted:
Oft times you think and think and think
Alas, never still could find the link.
Do you agree?
