I didn't know what there was to say regardless.
问题描述：
I didn't know what there was to say regardless.
高手们请帮我分析一下这个句子的结构.
“what”是做什么成分的,为什么用regardless,而不是regardlessly?
答
我不知道有什么话可以无所顾忌地去说.
1. what there was to say regardless是know 的宾语从句；
2. what是say 的宾语,即：说什么；
3. regardless和regardlessly都是副词,但是意思大相径庭,前者“不顾后果”,而后者“不受注意地, 毫无价值地”
