（1)主語從句中的虛擬語氣
在“it is (was) +形容詞（或過去分詞)+that…”結構中，如果形容詞或過去分詞表示建議、命令和要求等，那么that引導主語從句中的謂語動詞要求用虛擬語氣，其形式為：should+動詞原形。

【真題體驗】
Countless divorced politicians would have been elected out of office years ago had they even thought of a divorce, let alone gotten one. [2002, 完型]
分析：
A. 分析句子結構。該句主句是Countless divorced politicians would have been elected。had they even thought of a divorce 是從句，是省略if的倒裝條件句。out of office years ago和let alone gotten one都是狀語。
B. 分析虛擬語氣。主句Countless divorced politicians would have been elected和從句中 had they even thought of a divorce中的謂語動詞分別是would have been elected、 had thought，體現(xiàn)了虛擬語氣。其中，從句是省略了if倒裝條件句。
C. 譯文：現(xiàn)如今，許多政客都紛紛離婚，這要是在幾年前都是不可能的。那時，不說真的離婚了，只要他們有離婚的想法，就一定會被趕下臺。
