IF引導(dǎo)的三種時間虛擬條件句結(jié)構(gòu)
在虛擬語氣中，if引導(dǎo)的虛擬條件句是最為核心的，很多學(xué)生問我對應(yīng)的三種時間結(jié)構(gòu)是什么，今天我給各位同學(xué)進(jìn)行了羅列。
| 從句 | 主句 | |
| 與現(xiàn)在事實(shí)相反 | if + 主語+ did/were… | 主語+ would/could/should/might do… |
| 與過去事實(shí)相反 | If+主語+had done… | 主語+would/could/should/might have done… |
| 與將來事實(shí)相反 | If+主語+ did/were to do/should do… | 主語+ would/should do |
給大家附上三個例句：
If I were you, I would try it. 與現(xiàn)在事實(shí)相反
If he had realized that, he would have run away while there was still time. 與過去事實(shí)相反
If it were to/should rain tomorrow, the meeting would be put off. 與將來事實(shí)相反
