Perhaps it's a regional thing then because I am from the UK (south) and would say 'pass' and it's more common here to hear 'time passes' rather than 'time goes by'. I also opted to say 'pass quickly' which was marked incorrect so of course there is a good chance that just because that is how we would say, it doesn't make it correct.
It might have been marked incorrect if you did not type "very" between "pass" and "quickly," since the Duolingo sentence also includes «muito». I typed "The year is going to pass very quickly," and it was marked correct.
"The year will go by quickly" was also accepted for me 12/4/2015. Perhaps some people feel that "quickly" = "very fast".
Eu traduzi a frase como: The year is going to GO BY very fast. É 100% correto, mas o duoLingo diz que so é bom dizer "GO very fast" ou "PASS very fast." Para este frase, o mais comum em inglês americano á o que eu escrevi: GO BY.
We can say: The year will PASS BY very fast. Not just "pass." It needs to be "pass BY" or "go BY." Also, we can say either "The year will..." or "The year is going to..."
I agree. We don't say the year will pass or the year will go, we say the year will go by quickly.
Why is "quite quickly" wrong, please!? Also: again the shall should be accepted.
