3.Some 40,000 former officials from the communist-era in Poland have had their pensions halved.

have had their pensions halved是have sth done的结构

have sth. done，have sb. do sth 与 have sb./sth. doing 三种结构进行简单的分析和归纳。

　　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. 你最好把车子开慢点。
