第1题：去掉 go to。因为accompany 通常不用于accompany sb to do sth 这一句式。要表示陪某人去某地，英语直接说 accompany sb to a place。如：
I must ask you to accompany me to the police station. 我得要求你陪我去一趟警察分局。
第2题：去掉 with。因为 accompany 表示“陪伴”时是及物动词，其后可直接跟宾语。
He said he was going to accompany her home. 他说他将陪她回家。
Wherever his boss went, he would accompany him. 无论老板去哪里，他都陪伴身边。
