How can i know whether it is simple or continous like in English?
I'm pretty sure you can't
En ik drink bier.
no surprise there
is there a different pronunciation i'm not hearing between 'bier' and 'beer' (bear) ?
I believe bier is pronounced bee-er whilst beer is pronounced bay-er.
Why is he drank beer wrong
Because drank is past, and drinkt is present
You should be more flexible on spelling, I accidentally wrote beer, and got it wrong.
if you were translating into dutch, then beer is an english word so it will be regarded as a miss translation.
