英语问题，简单！

have sth done, have sb do sth 与 have sb/ sth doing
出现了 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。本文拟对这三种结构作一简单的分析和归纳，供同学们学习时参考。

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。

Don't forget to have Mr Brown come to our party. （ = Don't forget to ask / invite Mr Brown to come
