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.
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.
have sb doing sth 有两种意思：
1.使某人开始做某事
2.劝说或命令某人做某事
have sb do sth 是美式英语,只有 have sb doing sth 的第二种意思.
As his parent,you shouldn’t have your child reading such a book
不应该那么早让孩子开始读如此深奥的书
have sth． to do这一结构中的have意为“有”,即“有某事要做”.
have sth.to do 是要干某事,这件事是由主语来做的,而have sth.to be done是有事要做,这件事本质上不是由主语来做的．
比方说：I have my dinner to cook.这里的饭是我做的,而I have my hair to be cut.头发不是我来剪的,是理发师,但我要剪头发.
have sth.to be done是有些事情等着被做,其中的不定式表此时目前还没有被做.而have sth.done指的是此事已经被做完.二者有一个时间差.
另外要注意的是have sth.done短语中,做这件事情的人一定不是你自己而是别人
I have my hair done this morning.肯定是别人帮你剪的头发.因此如果是自己做的事情不能用此短语.
have anything to be done应该是用在疑问句中.如：Do you have anything to be done?意思是你还有什么事需要（我来）做的么?
