sb have/has done have/has not done have/has sb done What have/has sb done?
done
指什么
能用物体名称吗
比如apple等

have sb do sth have sth done
have the sthdents clean the classroom
have my hair cut(过去分词) have my bike repaired

done 是 do 的 过去分词 have/has 后要加 过去分词 构成现在完成时

这里的done不是名词,而是过去分词.sb have/has done 是现在完成时态的肯定句形式,have/has not done 是否定句形式,have/has sb done 疑问句形式.What have/has sb done?特殊疑问句.建议看看现在完成时态的语法.
