Unit 9 假設語氣

1. 假設語氣（與現在事實相反/與過去事實相反）

說明：假設語氣在統測英文只會考：用 if 帶出「與現在事實相反」和「與過去事實相反」，時態使
用上記得都是往後退：與現在事實相反假設語氣中，if 兩邊的動詞用過去式；與過去事實相
反假設語氣，動詞則用過去完成式，但因為有助動詞，故主要句子改為：助動詞 + have + P.P.，
如下圖箭頭所式。

過去完成式 過去式 現在式 未來式

S + had + P.P. S + Ved S + V/be Ving S + will/be going to

公式： 與現在事實相反：If S+Ved/were…, S+ should/would/could/might +V
與過去事實相反：If S+had P.P.…, S+ should/would/could/might +have P.P.

例句：
(1) If I were you, I would not do it.
如果我是你，我不會做這件事。（Be 動詞一律改為 were）

(2) If I had a lot of money, I could buy a house in Taipei.
如果我當初有很多錢，我就會在台北買一棟房子。
(3) If I had called you last night, I would have known the joyful news.
如果昨晚我有打電話給你，我就會知道這令人開心的消息。

小試身手
重 組：try my best / to find cure to the rare disease / a scientist, / I could / If I were

____________________________________________________________________
中翻英：如果當初 Polly 有聽我的忠告，她就不會弄傷自己了。
____________________________________________________________________

答案：
If I were a scientist, I could try my best to find cure to the rare disease.
If Polly had followed my advice, she would not have hurt herself.

2. wish/as if; as though/it is time that

說明：wish（但願）…；as if/as though（彷彿）…；It is time that（該是…的時候到了），這三個句
型後接假設語氣的句子，除了 it is time that 接與現在事實相反的假設語氣，wish；as if/as though
後，可接與現在事實相反的假設語氣及與過去事實相反的假設語氣。
例句：

(1) I wish you were here/had remembered my birthday.
我但願你現在在這裡/你當初記得我的生日。
(2) He acts as if he knew everything/as though nothing had happened.
