Present Perfect or Pr. Simple when there are "always" in the sentence?
In my grammar is written that "you can use the Present Perfect with just, already, yet, ever, never, this month, this year etc., since, for." Nothing is written about using this tense with "always".
There are examples of "always" with Present Cont. et Present Simple, like "I always go to work by car. & You're always watching television. You should do something more active".
I need to complete the sentences using Present Simple or Present Perfect.
The Coopers (always / live) in London. She (always /know).
I thought I should to use Present Simple.
But I found in other text book such sentence "Mrs. Brown has always lived in that street".
And I don't know now when I should use Pr. Perfect or Pr. Simple if there is "always" in the sentence?
