✔ 最佳答案
你提到的possibile situation(即是現實有可能發生的。),就算是你想象,但只要有可能發生是,就用first type condition sentence。"if clause" 提出了Possible happen in the future 的事件,而 "main clause " 則是假設事件發生後,其結果如何。
例子:
If I study hard, I will pass the exams.
但如果你假設或想像的事是現在的,但一定不會發生,就用second type conditional sentence.
最常見的例子:
If I were you, I would study hard. 因為「我」永遠都不會是你,所以一定不會發生。
以下資料作參考:
Type 0: main clause 一定發生
if Clause: Present Tense
Main Clause: Present Tense
Example: Ice melts if you heat it.
Type 1: if clause 可能發生
if Clause: Present Tense
Main Clause: Future Tense
If I find her address, I will send her an invitation.
Type 2: if clause 一定不會發生或很非常不實際,屬於現在式
if Clause: Past Tense
Main Clause: Future Past Tense
If the Stock Exchange rose by another 1000 points by the end of the year I would go on a round-the-world-tour next year
Type 3: if clause 在過法沒有發生
if Clause: Past Perfect Tense
Main Clause: Future Past Perfect Tense
If you had called me I would have come. (但你之前沒有叫我,所以用type 3)
