Quote:How about this:
-(The) annual Sports Day will be next Wednesday.
It's a regular event, held every year, but the lack of THE seems strange....
First, what do you think, WB, from what you have learned so far about articles and from how similar situations are handled in the English language?
Attempt to analyze it, giving your reasons. That may well reveal things that could make it easier to give you more informed assistance.
