英语中集合名词作主语,其后谓语动词数的形式?

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）
希望能帮到你!
