从句用一般过去时,表示在他意识到的是家庭对他很重要,不论是过去还是现在,即使是现在,依然是重要的,因此从句与主句时态一致.如果从句用过去完成时,表达的意思则是家庭曾经对他来说很重要.
陈述一件事情,一般过去时刚刚好
left 和know 两个都是非延续性动词不需要用完成时。从句用一般过去时,表示在他意识到的是家庭对他很重要,不论是过去还是现在,即使是现在,依然是重要的,因此从句与主句时态一致。
did he begin
这是强调句式,主句谓语部分倒装
还原:
He didn't begin to know...until he left home
一般来讲,not...until...的主句不用过去完成时。 又如
I didn't get up until 7:30 this morning.
