假設語氣 IF 總整理

Penny 來電表示不瞭解與未來事實相反的句子. 藉此我將所有假設語氣整理一下

一般與未來事實相反的句子和與現在事實相反是同一種句型

If + 過去簡單, 主要句子用 should / would/ might/could +原形V
★ If 句中的動詞為過去式，而Be動詞不論人稱為何，一律用were ★


If I had enough money, I would buy you a house tomorrow.  (事實明天我不會買,因為沒錢)
If I were you, I would not do it.

與過去事實相反


If + had +p.p. , 主要子句用 should/would/ might/could+ have + p.p

If I had finished my homework, I should have earned the gift yesterday.
昨天如果我寫完功課, 就可以得到禮物 (事實沒寫也沒得到禮物)
If you had told me about the problem, I would have helped you.

＊ 結果句的意思和「現在」有關時，其動詞要改成 would +原形V。此句型通常和now,today等字連用。
If you had told me about your plan, we would go shopping today.
(你如果告訴我你的計畫,我們今天就可以去購物了)

與未來事實相反而且幾乎是「不可能發生的事」


If + were to +原形V , 主要子句用should / would/ might/could +原形V

If the sun were to rise in the west, I would fall in love with you.
如果太陽從西邊升起,我會愛上你 (事實不可能)


與未來事實相反 有”萬一”的解釋

If + should +原形V, 主要子句用should(或 shall)  + 原形V
                                                    would(或will)
                                                    might(或may)
                                                    could (或can)

If it should rain tomorrow, the picnic will be canceled.   萬一明天下雨,野餐會被取消


a. If sun were to rise in the west, I would not change my mind.

b. If I were to be reborn, I would be a musician.

c. If I should fail, I would (will) do it again.
d. If it should rain tomorrow, the picnic will be canceled.

所以不能只說與未來事實相反,要更近一步說出是那一種語意才有辦法決定正確的句子.
