为什么一个是 to have sb do ，一个是 have sb done？

老师，您好，请问support为什么用的原形呢？不应该是supported吗？


The World Bank Institute co-sponsored the event. To Katrin Verclas, it was a good sign to have the World Bank support such open discussions about failure.——VOA


For reference: The creator of FAILFaire says this is true not only with technology but other projects as well. Ms. Verclas hopes nonprofits in other industries and fields will create their own versions of FAILFaire. A second FAILFaire took place in July in Washington. The World Bank Institute co-sponsored the event. To Katrin Verclas, it was a good sign to have the World Bank support such open discussions about failure.


老师，我在The Economist上看到了这句：Since the fishingcrew and its captain were arrested, Chinahas continually ratcheted up the pressure to have them returned. 这里have后面的return形式是returned，那不是和support同样情况吗？
谢谢老师~~

have 的使役用法有三种：

• have sb./sth. do (强调sb主动去做)
• have sb./sth. doing (强调主动且延续)
• have sb./sth. done (强调被动)

第一个例子 to have the World Bank support 中的 World Bank 有自由意志去做还是不做 support 这件事。
而第二个例子中，一开始，the fishingcrew and its captain 被 arrested 了，说明他们失去了人身自由，他们是不能主动地 return 的，只能“被”returned”。
