The sale usually takes place outside the house,with the audience___on benches,chairs or boxes.
A:having seated
B:seating
C:seated
D:being seated
答案是C
D为何不可以？表示一种坐的状态，相当于who is seated？

Answer 1

seated=sitting
当seat用作动词时，意为：1. 使坐下，使就座；为…领座，帮…找座：
to seat oneself in the sofa 坐在沙发上
所以，当seat单独（没有宾语）作谓语时，就用be seated; 作宾补时，一般用seated=sitting
如：Please be seated. He seated himself in the front.
这里是with + O + OC
所以，用seated而不用being seated，因为being done表示进行。
一般在宾补时可以用sitting代替seated

Answer 2

但是现在分词强调的是动作。而过去分词强调的是状态，如Lost in the forest for two days,he felt the least courage to live on. Determined to leave the city,he quit the job.这里我们都不用having been lost, having been dertermined. 再如The thief was taken away with his hands tied. 强调被绑的状态，而不是正在被绑，所以不用being tied.

Answer 3

在英语中 有些动词需要用被动表示主动

例如此题 用seated 因为be seated on 是固定短语 当它用独立主格结构或者作后置定语时 只要与主语是主谓关系 就要用seated 若后面没有介词on 则用seating
