✔ 最佳答案
question 1:
answer: 兩者皆非 請用 I’ve finished Sth. 例: I’ve finished all the cleaning chores in twenty minutes. I finished all the homework two hours ago. I’ve completed my military service. (已服完兵役)
I’ve moved to Taipei since two years ago.
question 2:
answer:
因為它是be動詞 (am/is/are)的過去分詞,所以它的句子結構一定是動用到be動詞
例: I’m a college student. (我現在的身份是大學生)I’ve been a college student for three years. (我當大學生已經三年了)
question 3:
answer:
嚴格來說過去的事一律用過去式但還要看前後文的完整敘述來搭配
例:When I was (過去簡單) little, I was (過去簡單)quite shy. But, now I am (現在簡單)much more confident.I have just eaten (現在完成)my breakfast, so I’m not hungry now.= I just ate (過去簡單) my breakfast, so I’m not hungry now. (請注意: 不是所有情境皆可做這種代換)The train had left (過去完成)the station when we got (過去簡單)there. (這兩個動詞原則上都已過去了,但在這種情境裏發生在前的用過完但在後的用過簡)
