The teacher together with his students______(work)happily now.

问题描述:

The teacher together with his students______(work)happily now.

is working,

is working ,关键是看真正的主语是the teacher。

working

is working千万不能写成are working。。你原来的问题被删掉了??

正确答案是 is working
together with his students作插入语
你记住 如果有together with,谓语动词的单复数看together with前面的那个名词 不能看后面
