一个时态问题求解答

Shortly after we( ),a waiter came over to our table with a smile .
A .were saeted B .seated D.had seated
答案选A，为啥啊，不是“我们先坐下，然后服务员过来微笑”吗，came是过去时，坐下在微笑前，选d过去完成时，表示过去的过去啊？

Answer 1

Shortly after we were seated,...这个句子不是时态问题，因为有after来表示动作的先后顺序了，后面不需要考虑时态“过去的过去”。
seat 这个词，应该是及物动词，所以要说seat sb，然后考虑被动语态。
举例说明:
1.He sat in the room.
=He seated himself in the room.
改为被动语态是:He was seated in the room.
2.I saw him sitting in the room.
=I saw him seated in the room.
