（2）have作为完全动词还可以构成使役式，其形式为： have+名词或宾格代词+动词的过去分词。由于have是完全动词，所以其疑问句与否定句由do/did构成。与被动语态相似，使役式着重表示的是对某物（或某人）做了什么而不是某人做了什么。试比较：

用被动语态或使役式时，我们可能不知道或认为不必指明为我们服务的人是谁。然而，使役式比被动语态更加强调“使”别人为我们服务这一事实。我们要表示让别人为我们做某事时，通常不用主动语态。让别人给理发时，不可说I want to cut my hair而要说 I want to have my hair cut。

使役式也可以用以指人：

While I'm away, I'll have you looked after.

我不在的时候，我会让人照顾你的。
