Hello, Leegoni:

Here is an explanation that seems to help many people:

"Something happened in the past that still touches the present."

1. My family moved to this city in the 1940s. It is now 2016, and I am still living here.

a. I have lived in this city since the 1940s. / I have lived in this city for 70 years.

2. Princess Elizabeth became the Queen of the United Kingdom in the 1950s. She is still the Queen.

a. Queen Elizabeth has been the Queen since the 1950s.

3. Mona (sees Raul at 10 a.m.): Hi! I'm going to the cafeteria. Would you like to join me for breakfast?
Raul: No, thanks. I have already eaten breakfast.
Mona: When did you eat?
Raul: I ate breakfast at 9:00 a.m.

a. Raul did something in the past, and what he did still touches the present because -- in theory -- the time for breakfast does not end until NOON (and it is only 10 a.m. now).

The Present Perfect is used in adverbial clauses of time after the conjunctions when, till, before, after, as soon as to denote an action completed before a definite moment in the future.

Don’t buy any more meat to-morrow until you have spoken to the mistress about it.

I am not going till you have answered me.
