What surprised me most was to see some of the village people

B。seated 为正确选项。seat这个词,做动词时,是“使坐在。。。”的意思,当表示“某人坐在。。。”的意思时,要用过去分词的,不能用现在分词。而sit则和它相反,都是用主动式的。这是seat和sit最大的区别。试比较：I saw him seating in the room。I saw him seated in the room。My father was sitting in the room。My father was seated in the room。
