a. ‘I read the report this morning’ is in the past simple tense, describing a completed action, something which is over, whereas ‘I’ve read the report this morning’ is in the present perfect tense, indicating that the action is not necessarily complete and so the sentence might continue ‘...but I need to look at it again this afternoon.’
b. The difference in meaning between these two sentences is dependent on the word ‘might.’ In the first example might could be substituted with ‘should’ or ‘ought’ whereas in the second example the ‘might’ expresses more of a possibility and could be substituted with ‘may’.
