A car carrying a bride to her wedding has slid across the road and gotten stuck in a snowbank, but the state police have sent out an SUV to pick her up. The wedding has gone on as scheduled.
I changed the details there, but that's a sentence construction I just read in a news story. Now I know that journalism has an odd way with tenses (most headlines in present tense, for example), but this really stopped me. Did it just happen, as I assumed from the present-perfect (has slid)? No, it was earlier today. The "state police have sent out" seems to me to be saying that the SUV hasn't gotten there yet. But the wedding "has gone on"-- so obviously the SUV got there, picked up the bride (this actually happened to someone I know, btw-- you should never schedule a wedding in the winter in Northern Indiana... another couple I know -- also a January Indiana wedding-- had to move their reception because the snow-laden hall roof collapsed) -- what was I saying? Oh, yes, present perfect.
What does present-perfect tense imply to you? When you read that a car "has slid across the road," what does that mean to you about when it happened?
It's a bit confusing to me because "has" makes me think that the action happened very recently and maybe isn't concluded fully. But if the wedding took place, obviously she didn't just get stuck in the snowdrift. So that was sort of misdirective, that present perfect.
When do you use present perfect?
