-Did you have anyone-----(water)the trees? -yes,I had them -

water watered
原因：have sb do
have sth done
have sb doing
have sb done
三者有什么区别?
像have sb ……这类多种形式的对于have sth ……有么?如果有,有什么区分?

答：have sth. done,have sb. do sth 与 have sb./ sth. doing 三种结构,不少同学对这些结构区分不清,把握不准.现在我对这三种结构作一简单的分析和归纳,供你学习时参考.
一、 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.
二、 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.
三、 have sb. / sth. doing
“ have +sb. / sth. （宾语）+ 现在分词（宾语补足语）”意为“叫 / 让 / 使某人做某事或让某种情况发生”.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.
