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。
Don’t forget to have Mr Brown come to our party. （ = Don’t forget to ask / invite Mr Brown to come to our party. ）
别忘了让布朗先生来参加我们的晚会。
3. have sb / sth doing
“ have +sb / sth （宾语）+ 现在分词（宾语补足语）”意为“让某人/ 某物处于某种状态”。宾语 sb/sth 后面用现在分词作宾语补足语，表示宾语与现在分词表示的动作之间为主动关系，且动作正在进行。例如：
Don’t have the baby crying！ 不要让婴儿啼哭！
Don’t have the dog barking much，Lilin. 李林，别让狗狂吠不停。
You’d better have your car running slowly. 你最好把车子开慢点。
