Student or Learner
I am learning English. I wonder if anyone could tell me if this sentence is correct and why?
"They have repaired the car yesterday."
"They have repaired the car." Have repaired is the present perfect tense. Although the car was damaged, it is now repaired. So: Have they repaired the car yet? Yes, they have. Because it's a present tense, yesterday does not fit.
"They repaired the car yesterday." Repaired is just simple past tense, so yesterday fits.
