Past tense VS present perfect?       Hello. Let's discuses!!      
Sam is my boyfriend. We are going to have a date on Sunday. We've been dating for only a few days. I have a Dad. We see each other every day. 
Today, it's Sunday morning. Sam picks me up and we go to the beach. 
He asks : 
1. Did you tell your dad where you were up to? 
2. Have you told your dad where we've been up to?   
I think they mean the same thing, but the second one is harsher than the first one. Am I right? If we want to talk about something happened in the past casually, it is unnecessary to use the present perfect tense, right?   
A. Did you realize he is a bad guy? 
B. Have you realized he is a bad guy?   
Are there any differences in aspect? I think  
A focuses on the action , realize, in the past, while B is focused on the result, "do you know it now?"   
Am I right? Thanks!      |
