题目

When I arrived, I found the boy_____there A seating B seated C is seating D satted
答案、、B、、seat应这样使用sb be seated.所以seat和boy是被动关系,宾不和宾语是被动关系,故宾不应用过去分词...被
动形式表主动意义,常见的用被动形式表主动意义的词或词组有以下这些：　　1．be seated坐着,就座,相当于seat oneself.如：
　　He is seated on a bench．→ He seats himself on a bench．
　　他坐在凳子上.
　　Please be seated,ladies and gentlemen!
　　女士们,先生们,请就座! 既然（用被动形式表主动意义的词或词组有以下这些：
　　1．be seated坐着,就座,） 那还为什么（sb be seated.所以seat和boy是被动关系）呢?

答案

这里是省略了who was,不违背be seated的用法
