You use a plural count noun with no article if you mean all or any of that thing.
I don't like dogs.
Do they have children?
I don't need questions. Give me answers!
I don't understand what "all or any of that thing" means?
The above guideline makes sense in general sentences such as "he likes apples" ("he likes all apples in the world") or "he doesn't eat apples" ("he doesn't eat all apples in the world").
But, what about specific sentences? Let say, there is a man. He has 3 apples with him. He is holding an apple & eating that apple. These other 2 apples are on the table. Which would I say?
"He is eating some apples" sounds ok.
"He is eating 3 apples" could be wrong to me because he may eat up 3 apples but he may eat only 1 & then stop eating.
"He is eating apples" could mean "He is eating all apples in the world"
The above rule is ok for sentences refer to general things such as "He likes apples" or "He doesn't eat apples" But is that rule ok for sentences refer to specific things such as "He is eating apples" or "I ate apples yesterday"?
So does the above rule only apply to some certain sentences?
