who are you talking to on the phone?on the phone做什么状语

题目

who are you talking to on the phone?on the phone做什么状语
who are you talking to on the phone?on the phone做哪类状语

答案

who 疑问代词 在句中作主语,也是to的宾语,即介词宾语
are you talking to 在句中充当谓语部分.
本句式现在进行时的特殊问句形式.
如果用陈述语序的：You are talking to who on the phone.
on the phone 就是在句中作地点状语的.
