问题：英语问题Thesaleusuallytakesplaceouts 
The sale usually tas place outside the house,with the audience___on benches,chairs or boxes.A having seated   B seatingC seated          D having been seated这题答案是c,但我觉的应该选b,with +n +ving,可为什么答案是c呢，帮我分析下好伐？
回答：答案应当选这里要区分好两个动词：sit, 和 seatsit,vi.用法: t……坐下seat vt. 用法：1、容纳：eg.  The theater seats (is seated for)two thousand.2、使……就座  eg. She is seated over there. = She sits over there. 她在那边就座。（注意例句中：seat的逻辑主语为人时，使用被动态；逻辑主语为某一地方时，使用哪个主动态）而本题中，若按你的理解，with +n +ving， 就应当是 sitting;with the audience sitting on ... = with the audience who are sitting on ...而动词seat使用过去分词表示被动意义：with the audience seated on ...= with the audience who are seated on ...（自己的浅见，不一定对，但可以帮助理解，希望能对你有所帮助。）
