Your math instructor would have been happy to giveyou a makeup examination had you gone andexplained that your parents were ill at the time.
译文：
如果你当时解释说你的父母那时都生病了，数学老师就会愿意让你补考的。
点睛：
本句是省略if的虚拟条件句，助动词had前置构成了倒装。条件状语从句采用了过去完成时表示对过去事实的假设，主句的谓语部分相应地采用了would have done的形式。
考点归纳：
虚拟语气表示一种假想或主观愿望，一般有以下几种情况：
*用动词原形表虚拟。
God bless you.愿上帝保佑你。
*用过去时表虚拟，表示与现在事实相反;若谓语为系动词be则一律用were。
If only l were not so nervous.
我要是不那么紧张就好了。
*用过去完成时表虚拟，表示与过去事实相反。
1 wish I hadn't done so.
真希望我当时没那样做。

译文：
在这些问题得到解决之前，研究行为的技术手段会继续遭到排斥，解决问题的唯一方式可能也会随之继续遭到排斥。
