I wrote about the present perfect simple some time ago as well. 

There, I explained why 'I've lived in Seoul.' doesn't imply you're living in Seoul now

If you want to say where you liveyou just say 'I live in ....' this means you started to live there at some point

in the past and you're still living there. It's absolutely not necessary to say 'I've lived in Seoul.', which sounds

like you have the experience of having lived in the city. 


For your 'I've lived in ...' to mean that you started to live there in the past and living in that particular city

is still true now, you've got to have a 'time reference' that links the past to now as in, 

'I've lived in Kyoto all my life.' Otherwise it can't be an ongoing event because of the missing link. 


If you're experiencing a lot of water drops falling onto your head and shoulders, you say, 

'It's raining.' If it's stopped, you say 'It (has) stopped raining.', but not 'it's rained.' 


If you REALLY REALLY want to say it started to rain some time ago and it's still raining, then say 

'It's raining.' again. 'It's raining.' means it started to rain in the past and it's still going on, which is 

exactly what you initially wanted to say. Don't say 'It's rained.' for that. 'It's been raining.' doesn't

mean it's still raining either. c-lick on the link at the top of the page for more information. 


I pulled up my socks a little bit this time. Hitting the shift key is shitty. It's such a hassle.
