I think it is there but is only barely emphasized because the vowel sounds bleed together as do the two /l/ sounds. I think the point for us language learners is to know that it is properly there before we learn to speed up the words and de-emphasize the individual phonemes. It's tough, but I think it'll pay off in the long run. :-/
I'm pretty sure. I'm less concerned about the marking and more concerned about knowing the correct form: the definite article is only necessary if you are referring to a specific instance? This sentence should translate as, 'We drink the milk', referring to a specific volume of milk. If I wanted to say that I drink milk in general then I could say, 'Bevo latte'? Is that correct?
