这句话的完整情景如下：
How about you tell me about you?Like,um,howd you get this van?And why asking total strangers questions like this is so important to you.
句子Why asking strangers questions is important to you中，asking是动名词还是分词？主语是哪个？假如这是个疑问句，为何不将is提前变为“Why is asking strangers questions important to you?”
why asking total strangers questions like this is so important to you.
1. 划线部分是的动名词短语，作句子的主语。
2. 这是口语特点。这是个 why 引导的特殊疑问句，但用了陈述句的语序，句末用句号代替问号。
3. 如此处置，是由于考虑到主语太长，没把 is 提前，防止 is asking 连在一块产生歧义。
4. 假如用形式主语 it，把动名词短语后置，倒装就非常自然：
Why is it so important to you asking total strangers questions like this?
