I think that it's because the presence of "the" means a specific school, which is hard to justify when the sentence is supposed to mean that you have begun classes and go to school regularly.
I don't quite understand how my answer is incorrect. What is the difference? You said, "We already go to school," and I (incorrectly, you said) put, "We already are going to school." Is this one of those subtle Russian verb things that doesn't exist in English?
"We already are going to school." This seems to me that it could very easily mean "we are going to school everyday".
As far as I know English, "every day" implies that Present Simple is needed rather than Present Progressive. I.e., we go to school every day, not are going.
You "are going" at the moment, you "go" generally, because you're a pupil. And here you уже = already are a pupil.
Seems like it should either say "We already left for school" or "we already started school" or "we already finished school" or "we already went to the school building" .. no context at all here in the written sentence.
The solution seems really wierd to me in english. Kind of broken. We already went to school is more accurate?
My question had words given, so 'go' was not an option, only 'walk'. 'They already walk to school' sounds different to 'they already go to school', as the former is saying they get to school by walking (not driving), and the latter that they are old enough now to attend school.
