16.4 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.
