Have sth done 与 have sth do在用法上有什么具体区别?

have sb.do sth:使某人做谋事
have sth.done:可以表示无意识的被动行为或有意识的让别人替自己做事
1.have sth done
“ have + sth （宾语） + 过去分词（宾语补足语）”意为“让 / 叫 / 使 / 请别人做某事”.宾语 sth 后面用过去分词作宾语补足语,说明 sth 与过去分词表示的动作之间是被动关系.例如：
We had the machine mended just now.
我们刚才请人把机器修好了.
He has had his hair cut.他（请人给他）理发了.
The patient is going to have his temperature taken.
这个病人准备请 / 叫 / 让人量体温.
2.have sb do sth
“ have + sb （宾语） + do sth （宾语补足语）”意为“让 / 叫 / 使某人做某事”.此结构中的 have 是使役动词,sb 作宾语,其后的 do sth 是省去 to 的动词不定式作宾语补足语.例如：
The boss often has them work for 14 hours a day.
老板经常要他们一天工作 14 个小时.
I'll have someone repair the bike for you.
我会让人为你修理自行车的.
