集合名词作主语时,谓语的形式要与主语的概念一致.举个例子：
Our group are visiting the meseum next week.(我组全体成员）
Our group is assigned to take the first bus.(我们小组）
某些集合名词如：audience,firm,class ,government,party,board,couple,crew,committee,family,public,team,group 等既可作单数,也可作复数.当一个集合名词可看成各个成员是,谓语用复数；看作整体时,谓语用单数.例：
The average family is a great deal smaller than it used to be.(家庭）
My family are going with me.(家人）
