Does an existential sentence with "有" only carry a non-specific noun?

Question

Sentence 1: 桌子上有一本作业 Sentence 2: 桌子上有我的作业 I think both sentences are correct. However, I just watched a grammar video which mentioned the existential sentence with "有" can only carry a non-specific noun. If so, "桌子上有我的作业“ wouldn't be correct, because "我的作业" is specific. So I am confused. Can anyone explain this?

Answer 1

Hi 同學

桌子上有一本作业 and 桌子上有我的作业 both correct.

桌子上有一本作业 mean There is a homework on the table. (Didn't say whose)

桌子上有我的作业 mean There is my homework on the table. ( point on whose homework on the table)

Both grammar are fine, just they mean differently.

Hope my answer would solve your questions.

Answer 2

Ni Hao!

1.桌子上有一本作业。 incorrect

桌子上有一本作业本。Correct

After measure word, you should put a noun ( one thing).

有 here means there is or there are.

2 桌子上有我的作业。Correct.

我的作业 is a noun. it means all my homework.
