These facts alone make him an unlikely romantic parner for me, given that I am a professional American woman in my mid thirties.
I would like to know how to use Past paticiple in the frist of sentense such as given, I just know paticiple should be following "have" or that sentense is passive voice
"Given" begins a clause that you can take as being factual. The fact is "given" in the sense that you can accept it as being true.
"Given that x = 3, x + 2 is 5." This means, "Since we are told that x = 3 ..."; "Because we know that x = 3" ... etc.
