刘备与刘邦关系:请问have sb. do sth.和have sth. done分别是什么意思呢？？

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。

sb.和sth应该可以代入其他人或物吧
have sb. do是让某人做某事的意思 I have her bring me some flower.我让她给我带些花.
have sth. done的意思是完成了某个动作 I have my hair cut.我理了发.

第一句有点怪。不懂。
第二句.
have sth. done
的话。。意思是：我有事要做。
例句:Sorry,,Tom.I have sth. done.I can not play football with you.

错了请指教。。
我才高一。。
