新东方考研英语必背500句
第089句
countless divorced politicians would have been elected out of office years ago had they even thought of a divorce, let alone gotten one.
译文：在数年前，无数离婚的政治家只要有过离婚的念头就会落选，更不用说真的离婚了。
点睛：had they even thought...是省略if的虚拟条件句，因此助动词had前嚣构成倒装。因为要表达对过去事实的假设，所以从句用了过去完成时，而主句的谓语部分则相应地采用了would have done的形式。
考点归纳：和let相关的常见短语还有：
*let go放手，松开
let go! you’re hurting me.
松开手！你把我弄疼了。
*let sb. alone不打扰某人
i'm tired-let me alone!
我累了，别打扰我！
*let sth. go/pass对某事不计较
i know you didn't mean to hurt me, so i'll let it pass this time.
我知道你不是有意伤害我的，所以这次我对这件事就不计较了。
