    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:
    在虛擬語氣的從句中,動詞'be'的過去時態(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,就會去找他。
    If he were here, everything would be all right.
    如果他在這兒,一切都會好的。
    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. 在虛擬條件狀語中如果有were, should, had這三個詞,通常將if省略,主語提前, 變成 were, should, had +主語的形式。但要注意,在虛擬條件狀語從句中,省略連詞的倒裝形式的句首不能用動詞的縮略形式。如我們可說 Were I not to do., 而不能說 Weren't I to do.
