btw is there any diference in pronunciation 'live in' and 'living' and between 'coming' and 'come in' etc...?
A lot of problems are related to region. Basically each county in the Uk pronounces words in a slightly different way.
live in vs living. In lazy English some people will drop the 'g'. So, both will sound similar.
The two 'th' sounds are easy, but you need to watch the speakers mouth and understand that the sounds are connected to the way you breath or the way you blow the air out as you speak.
Practice this: thirty three thousand three hundred and thirty three.
