I do love / I love , what's the difference between them ?

[nesyan]

Hello everybody

I always read sentences which cofused me and i searched for the answer
but I didn't find anything

I love it / I do love it
I like it / I do like it
I live there / I do live there
I have a mobile / I do have a mobile
she feels it / she does feel it

what's the difference between them ?
when should I add do ?
and when should I remove it ?
why they add do/does before the verb ?

DO simply adds emphasis, either for its own sake: I do love Theresa,

or to contradict/correct.:

A: Surely you don't live in Durham?
B: I do live in Durham.

I speech, DO is stressed.

Do you know the word "emphatic"? Or what it means to "add emphasis"?

I live here -- This is a simple statement.
I do live here! -- This is an emphatic statement. Perhaps someone has suggested (or even insisted) that you do not live here. You want to be very clear that you do.
