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.
