真题体验
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. 分析句子结构。该句主句是Countless divorced politicians would have been elected。had they even thought of a divorce 是从句，是省略if的倒装条件句。out of office years ago和let alone gotten one都是状语。
B. 分析虚拟语气。主句Countless divorced politicians would have been elected和从句中 had they even thought of a divorce中的谓语动词分别是would have been elected、 had thought，体现了虚拟语气。其中，从句是省略了if倒装条件句。
C. 译文：现如今，许多政客都纷纷离婚，这要是在几年前都是不可能的。那时，不说真的离婚了，只要他们有离婚的想法，就一定会被赶下台。
