虛擬條件句的倒裝

虛擬條件句的從句部分如果含有were, should, 或had, 可將if省略，再把were, should或had 移到從句句首，實(shí)行倒裝。 Were they here now, they could help us. =If they were here now, they could help us. Had you come earlier, you would have met him =If you had come earlier, you would have met him.　 Should it rain, the crops would be saved. =Were it to rain, the crops would be saved.

注意： 在虛擬語(yǔ)氣的從句中，動(dòng)詞'be'的過(guò)去時(shí)態(tài)一律用"were"，不用was， 即在從句中be用were代替。 If I were you, I would go to look for him. 如果我是你，就會(huì)去找他。 If he were here, everything would be all right. 如果他在這兒，一切都會(huì)好的。

典型例題 _____ to do the work, I should do it some other day. A. If were I　　 B. I were　C. Were I　D. Was I 答案C. 在虛擬條件狀語(yǔ)中如果有were, should, had這三個(gè)詞，通常將if省略，主語(yǔ)提前, 變成 were, should, had +主語(yǔ)的形式。但要注意，在虛擬條件狀語(yǔ)從句中，省略連詞的倒裝形式的句首不能用動(dòng)詞的縮略形式。如我們可說(shuō) Were I not to do., 而不能說(shuō) Weren't I to do.
