有關英文Grammar 問題一問

It is OK in the sense of time.
But it is not very good in grammar:
My suggestion: I had just had/finished my dinner.

In general, English is not Math, so teachers will always tell us that we don't need to care so much about the time.
e.g. noon = [Math] 12:00:00
[Eng] around 12 o'clock

My conclusion: just - 你做完lee樣之後，做左一至兩樣野，就可以用just

Hope I can help you ^_^

更正上述內容：(我打錯了，一萬個對不起，所以加多一樣資料比你賠贘)
My suggestion: I [have] just had/finished my dinner.

補充：
Usage of "present perfect tense":
When that action/event affects your beings now, and it is in the past, not very long time ago

My suggestion is 英式英語.

有回答者寫:
"The dinner just finished.
Did I eat yet my dinner ?
I have had dinner just."

純文法角度去看, 請教讀者上面的三句是否對?

The dinner just finished = Someone just finished the dinner??
active 與 passive 無分別?

我同意回答者：Omega.

I just had dinner. ~ 美國人講多

I have just had my dinner. ~ 英國人講
or

The present perfect is the form of a verb that shows a period of time up to and including the present, formed in English with the present tense of the verb 'have' ,as in "I have had' and a past participle: when it is 8:00----9:00 p.m.
Just, already, yet are used with the simple past tense:
The dinner just finished.
I already had dinner.
Did I eat yet my dinner ?
OR:
The dinner had just finished.
OR:
I have already had dinner.
OR:

OR:
I have dinner from eight o'clock to nine o'clock.
OR:
I have eat dinner yet.
OR:
I ate dinner when it is 8:00 to9:00 p.m.

The present perfect is the form of a verb that shows a period of time up to and including the present, formed in English with the present tense of the verb"have' ,as in "I have had" and a past participle.8:00----9:00----9:20 pm when (09:20-09:00=00:20 min.)
