问题描述：
The teacher together with his students_______to visit the museum.
A.has been B.are
C.is D.have been.
为什么选C?
答
首先togehter with出现的话主语是togehter with前的人或物,所以是单数；
其次,has been to some place本身就是去过某地的意思,加了to visit就错了
be to do 是将要做某事的意思意思是按照主语确定谓语的单复数咯？呵呵，，小学没学好，抱歉了是的，谓语单复数用哪个是看主语的单复数形式的像这道题，如果不是together with 而是and，那么主语就有多个人，谓语就得用复数形式
