Please, help me understand the grammar behind "some" and "zero article".
As I know, we use zero article with plurals in the same cases when we use indefinite articles with singular -
- making general reference
- making mention for the first time
On the internet I couldn't find that "zero article + plural" is used while talking about something for the first time. Instead I could only find the rule that it is used for general reference. Is it so?
Here is an example:
"(Some ?) Computers were brought to me. They were expensive"
Would it be correct to say without "Some"? I understand that this is not a very natural thing to say, but from the position of grammar can it be used for the first mention? I assume that the listener has not heard about me buying any computers.
I also read that "Some" is an analog of a/an for plural, maybe this is why I couldn't find the rule of using zero article for first mention - "some" should be used instead?
What do you think about these questions?
