1. 答案：B.
解释：此题考查if引导的条件状语从句的虚拟语气.
were we to work another hour=if we were to work another hour
if从句如果有were/had/should,则可把这三个词提前至从句首,再去掉if.
3. 答案：A.
解释：it's required that-clause中,that所引导的从句需要采用虚拟语气,即从句谓语动词采用“should + 动词原形”构成,should经常可以省略.
该句答案A中learn=should learn.
D should have done是另外一个固定短语,意思是“当时本应该做某事（但实际上当时未做）”,should是不可能省略的,在本题中不可以使用.
