For a full understanding, we need some context (and it is required by the WR rules). Without any context, we can't tell which tense is appropriate and we can't say whether "during the day" fits.Have you been able to check your email during the day?
Were you able to check your email during the day?
I'd say that both are right, but I'd like to hear the opinion of a native speaker, please.
I would have 'were you' in that sentence, not 'have you been'. As baldpate hints in post #7, the present perfect is used to describe "an extended period of time, up to and including the present." It's not grammatical to use the present perfect in this case because of the adverb 'yesterday'. Without it, choosing the present perfect tense would make sense.Can someone tell me wether "where were you yesterday?" is completely wrong? And if it is, why?
