题目内容：

All the people presented at party were her supporters.(在people 和presented之间能加个who或者that吗

优质解答

presented at the party 是分词作后置定语,由于不是从句,因此不能加从句引导词.但此句可改成从句,加 that（不能加 who,因为被修饰的名词中有 all）后再加 were,即可改成定语从句.
全句：All the people that were presented at the party were her supporters.
全句：参加聚会的人全都是她的支持者.
