R.When I opened the fridge.
I found that the milk is stale.
In that case, could you please tell me which is more natural?
1）The milk expired.
2）The milk has expired. <- This one.
3)The milk is expired.
And is it possible to subsitute "off" for "stale"? Yes, stale milk is "off".
or "rotten" for "stale"? Not for milk. Use 'rotten' for meat, fruit and vegetables.
Many thanks in advance!
