Where is he/she from?和Where does he/she live?里面为什么does和is不同 同样是第三人称

Where is he/she from?和Where does he/she live?里面为什么does和is不同 同样是第三人称
from是介词,前面用be动词 he is from china
live是动词,前面用助动词do/does/did he live in china
疑问句是be动词或助动词提前is he / does he
供参考

这问题,问的很麻烦

因为is后面的词是介词from,be动词加介词短语构成系表结构。而does后面是live,live是实义动词,在构成疑问句时,要用助动词辅助完成句子结构,所以不能用be动词。回答形式也不同。例如:where is she from? she is from Sichuan. where does she live? she lives in Guangzhou....
