關於英文現在完成式的問題詢問

present perfect tense 的用法:
S + has / have +V-pp + for + 一段時間
S + has / have + V-pp + since + 一段時間 + ago
S + has / have + V-pp + since + 過去某時
S + has / have + V-pp + since + S + V-pt
It is (has been) + 一段時間 + since + S + V-pt

所以應寫成In the morning , I have ran from 10: 00am to 10:20am today

用 '' I have run from 10:00a.m. to 10:20a.m. todday.'' 比較好。

S + has / have + V-pp + since + 一段時間 + ago
He has played the violin since five years ago. ~ 錯
這個句子格式是錯

應該是:
He has played the violin for five years.
He has played the violin since 2009.
He started playing the violin five years ago.

You wrote down 10:23
That is 十點二十三分, (twenty-three minutes past ten)
Nowhere did the 發問者 mention anything about 十點二十三分

十點二十分 = 10:20
十點二十分零一秒 = 10:20:01
十點零三秒 = 10:00:03

The Present Perfect Tense is made by using the Present Tense of the verb to have and a past participle.eg:-run.
The Present Perfect Tense is used for an action just concluded when the resulting state is still present,eg:-
I have run from 10:00 am to 10:20 am today.
The Present Perfect Tense ,though it indicates an action that took place in the past, is associated with the" present "idea of NOW
Since you are using 10:23 for (10:23-10:20=00:03)=NOW
Hence ten-twenty-three can be used to describe Present Perfect Tense ,as it is=NOW

如果present perfect tense應該是 "have run"。

文法上Okay~但係如果你想講十點零三秒,就應該用10:20.03am 不只係10:20am
