Hello,
I'd like to ask for clarifications between two separate posts from this forum. I hope you can help me compare and understand the answers. Thank you in advance.
Link #1: Original Sentence: I
have improved the internal controls of the department.
Should Be: I
improved the internal control of the department.
Note: The person is no longer a member of the department.
Reason: The making of improvements happened when you were part of another department. You are no longer in that department. This puts up a barrier between the improvements and the present moment of the interview question which cannot be spanned with a present perfect tense. But if you still belong to that department,
'have improved... the department' makes sense. See detailed
explanation from the link.
Link #2: A. My time at X company
has shown me that I
've developed my analytical skill.
D. My time at X company
showed me that I
've developed my analytical skill.
Note: The person is no longer connected with X company. The person still has the skill.
Should Be or Acceptable: A and D
Reason: In A, all focused on the present situation, wheras in D, not completely focused on the present. A is not wrong in this case as per note above, but D is the suggestion. See detailed
explanation from the link.
Questions:
1. Why is the should-be answer in link #1 only accepts the simple past
'improved', while link #2 accepts sentence A with the present perfect
'has shown' when both contexts show that the person is no longer part of the department or X company?
2. In A and D, why is the present perfect
'have developed' correct when the making of developments happened when the person was part of X company? Don't you think this puts up a barrier between the development and the present moment of the interview question which cannot be spanned with a present perfect tense, which is the same reason as with link #1? Although the person
does still have the skill at the moment of the interview.
3. I don't quite understand the concept of focus of time in verb tenses. In A, all focused on the present situation with the present perfect. Don't they all refer to past actions, i.e. the
showing and
development happened in the past or when the person was part of X company? Please explain.
