He wrote the name down for fear that he should forget it.这句话中从句为什么要用should do?是否是虚拟语气?

for fear that引导的状语从句He wrote the name down for fear that he should forget it.这句话中从句为什么要用should do?是否是虚拟语气?
这是一个虚拟语气句型.
由连接词in case,so that ,unless,lest ,for fear that引起的状语从句中,谓语动词要用虚拟形式,即should(might,would)+动词原形.
She put a blanket over the baby for fear that he should catch cold.
她在那个婴儿身上盖上了毯子以免他着凉.
