Hjælp til lille afl.

Hej. Er der nogen der gider se efter om jeg har lavet rigtigt? Tak..

Oversættelse:
Peter skulle flytte til Århus for at studere matematik på universitetet. Heldigvis havde han ikke ret mange møbler, så det var let klaret. Hans mor gav ham mange gode råd om at spise fornuftigt og ikke bruge for mange penge. Peter kunne rigtig godt lide tanken om at leve sit eget liv og få en masse nye venner.
Engelsk:
Peter was moving to Århus to study mathematics at the university. Fortunately he did not have that many pieces of furniture so that was easily done. His mother gave him much good advice on eating reasonable and not using too much money. Peter really liked the idea of living his own life and getting a lot of new friends.

Opgaver:
1) Behind Winston's back the voice from the telescreen was still babbling away.
Hvorfor vælger man udvidet tid der med 'was still babbling'? Er det fordi det har noget at gøre med det bare kører i baggrunden?
2) There was of course no way of knowing whether you were watched at any given moment.
Og hvorfor vælges udvidet tid her med 'were being watched'? Forstår ikke funktionen..

Nå ja, og hvilken ordklasse tilhører simultaneously? Er det ikke et adverbium? :S
