Our school bus always (seats) more than fifty students,which,in fact,is not allowed.

问题描述:

Our school bus always (seats) more than fifty students,which,in fact,is not allowed.
此处主语的谓语动词用了原型seats.这是道语法题目,解释上说是当主语由表示地点的名词充当时,即为地点主语时,气候的谓语动词,在语态上不能用被动时态,而在时态上不能使用进行时.
我想问的是,这个语法属于哪部分语法啊,我没碰到过,有点迷惘.

这个词就按特殊用法记 最简单
“seat” 表示‘可容纳若干座位’
eg:
The theatre seats 2000 persons.
剧院能容纳两千人.
不用被动.
