文法上有沒有錯

有,

如果要成為1句完整的句子,必須要附合S+V+O的原則,
即是要有Subject(主語)、Verb(動詞)同Object(賓語)3部分.

Subject是指句子敘述何人、何物、何事.
Verb是用來表示一個動作.
Object是動詞針對的對象.



第1句冇咗個Verb(動詞)同Object(賓語).

正確答案:

1) I have breakfast at the breakfast table with her.



笫2句冇咗個Subject(主語).

正確答案:

2) We sleep in our eyes.

還有,
笫2句的意思有問題.
該是:
We sleep in our eyes closed.
我們在睡眠時眼睛是閉着的。

A sentence should at least contain subject and verb.
For example: I sleep => I = Subject, Sleep = Verb
I walk on the street => I = Subject, walk= verb

For 1st sentence you mentioned:
her and me (wrong, should be "She and I", her and me are "object")
no verb, at is not a verb
I suggest you may change the sentence as follows:
She and I eat breakfast at my coffee table.

For 2nd sentence:
no subject
and I do not get your meaning about "sleep in our eyes"
I suggest you may change the sentence as follows:
I watched my baby daughter sleeping comfortably in her tiny bed.

I wish my answer can help you.

1) her and me at the breakfast table
錯...
her 和 me用錯pronoun
應該是She and I
全句冇verb(動詞)...
所以不是一句句子

2) sleep in our eyes
冇subject
sleep=睡(verb)
in our eyes=在我們的眼睛裏
我就不明白這句在說甚麼。
是否一些中文意思的句子配上一些你以為的英文字詞。
例如：在我們的眼中他是睡著了
這類的東西。
