If I WERE rich , I would buy a car.
If more good NEWS WAS reported, we would feel more hopeful.
For the former, because it is a hypothetical scenario, we bring 'were' instead of 'was' even though we have 'I'.
But why we say 'news was' and not 'news were'? It is because news is uncountable? Or 'were' only applies to 'I'?
