與現在事實相反的假設 |
表與現在事實相反的假設,在 if 子句中用過去式,在主要子句中再用 would、should、could 或 might 加原形動詞。例如: ・ If I were the CEO, I would hire the other applicant. ・ If I had the power, I might hire both applicants. |
與過去事實相反的假設 |
表與過去事實相反的假設,if 子句裡用過去完成式,主要子句則用 would、should、could、might 加 have 和過去分詞。例如: ・ If I had known this, I wouldnt have said that. ・ If Tony had left earlier, he should have arrived in time. |
對未來強烈懷疑的假設句 |
因為未來時間尚未到來,所以說「與未來事實相反」並不恰當,我們只能說「對未來的狀況抱持強烈的懷疑」。欲表對未來的強烈懷疑, if 子句中可用 should 加原形動詞或用 were to 加原形動詞,主要子句則用 would、should、could、might 加原形動詞。例如: ・ If it should rain tomorrow, we would stay indoors. ・ If Emma were to become the boss, I might just quit. |
