1st Usage: If + somebody + did + something
Note: When we talk about the Present or the Past, we use Past tense following the subject.
Would you mind If I used your phone now?
Would you mind If I borrowed your car tonight?
Attention!
We may sometimes get confused by the subject. So pay attention to these two sentences.
Would you mind If I opened the window? (Shall I open the window)
Would you mind If you opened the window? (Can you please open the window)
Note: In the first one the person himself wants to do something and asks for the other's permission. However in the second one the person requests something from the other one to do.
2nd Usage: When we don't mention the subject we may just use Verb + ing
Would you mind taking this book back for me?
Would you mind sending that mail for me?
3rd Usage: Somebody's + Verb + ing
Would you mind John's staying here with us?
Would you mind My sister's coming with us to the picnic? ATTENTION
