形容词化的过去分词

4．注意的四种结构：

have something to do 有某事要做

have something done 使某事被做

have somebody do something 使某人做某事

have something doing 让某事一直做着

来自系表结构的过去分词（形容化）

有些过去分词(词组)因来自系表结构而不含被动色彩，如dressed like, dressed in, satisfied with, devoted to, tired of, born in, seated, pleased with, interested in, surprised at, prepared for, lost /absorbed in等。例如：

Do you know the man seated on that stone? 你认识坐在那块石头上的那个人吗？

Don't you know the girl dressed in a red skirt ? 你不认识穿红裙子的那个女孩吗？

有些过去分词因来源于系表结构,作状语时不表被动而表主动.这样的过去分词及短语常见的有：lost (迷路); seated (坐); hidden (躲); stationed (驻扎); lost / absorbed in (沉溺于); born (出身于); dressed in (穿着); tired of (厌烦)。

(2) Lost / Absorbed in deep thought ,he didn't hear the sound.因为沉溺于思考之中，所以他没听到那个声音。
