Are you sure that making up your own scenarios and then just asking us to choose between the tenses is actually helping you?
Yes.
I suspect you might find it more helpful to take time out to study the use of the tenses (using a good textbook, preferably with exercises and an answer key) until you really think you've got a handle on it.
I already know the basics, but I think my questions are specific and are not covered in grammar books. For example, the question in this thread is about backshifting in reported speech. Normally, grammar books tell us that if we have a specific time like "two days ago", then we shouldn't backshift. For example, if John said to me today: "I saw Peter two days ago", then in reported speech that becomes: "John told me today that he saw Peter two days ago." The past perfect "had seen" would be wrong in this case. On the other hand, if we don't have a time marker like "two days ago", then we should backshift. For example, if John said to me today: "I went to the supermarket and bought some fruit. Would you like an apple?", then that should be reported like this: "John told me today that he'd gone to the supermarket and bought some fruit. He then offered me an apple." So, in this case "went" becomes "had gone" in reported speech. But there are a lot of exceptions to that rule (hence my question in post #1). In the examples in post #1, there's the time marker "this morning", and both the speaker and the listener know that the seeing of the boss happened this morning. So, when that is being reported, it is correct to use the simple past "saw" because "this morning" is implied:
He told me today that he he saw you (this morning) and I asked him if you said "Hello".
On the other hand, it is also correct to use the past perfect "had seen" because the seeing happened before the telling:
He told me today that he'd seen you and I asked him if you said "Hello".
I suspected that both were correct, but I still had my doubts as to whether they indeed were. Since "this morning" is closer to the present than "two weeks ago", I thought that the simple past "saw" might be preferable with the former, and that the past perfect "had seen" might be preferable with the latter.
I wonder how this question is working out for you, EngLearner.
I came up with that question because I had my doubts as to whether the simple past and the past perfect were both correct. I suspected they were, but I wasn't sure. Now that I've been told that they're both correct, I'm no longer in doubt. I've learned something new.
Do you find it productive?
Yes, I do.
