选择题
Mary, along with her parents Hainan for a week and they will come back soon.
A．have been to
B．has been in
C．have been in
D．has been to
答案
B
题目分析: 句意：玛丽，和她的父母一起去海南一周，不久就要回来了。have been to已经去某处回来了，have been in已经在某处。根据 they will come back soon.他们不久就要回来了，可知还在海南，并且在那里一周了，along with her parents做状语，主语为Mary,故选B
