使役动词表示导致发生的动作。换句话说，当我有事情为我做的时候，我让它发生。换句话说，我其实什么都不做，只是让别人帮我做。这是使役动词的意思。中级至高级英语学习者应该学习使役动词作为被动语态的替代。英语中有三个主要的使役动词:Make, Have和Get。(有时也把let, allow, force等看做是使役动词）
Causative Verbs Explained
使役动词表示某人使某事发生的意思。使役动词在意义上与被动动词相似。
Verbs and Adverbs
下面是一些可以用来比较的例子:
My hair was cut. (被动)
I had my hair cut. (使役)
在这个例子中，意思是相同的。因为剪自己的头发很难，所以别人剪你的头发是可以理解的。
The car was washed. (passive)
I got the car washed. (causative)
这两个句子在意思上有细微的差别。在第一种情况下，有可能说话者洗了车。在第二段中，很明显说话者花钱雇人洗车。
一般来说，被动语态用于强调所采取的动作。使役动词强调某人导致某事发生的事实。
Causative Verb Examples
Jack had his house painted brown and gray.
The mother made her son do extra chores because of his behavior.
She had Tom write up a report for the end of the week.
第一个句子的意思类似于:某人画了杰克的房子或者杰克的房子是被某人画的。第二句话表明母亲使男孩采取了行动。在第三个例句中，有人告诉别人做某事。
Make as a Causative Verb
Make作为使役动词表达的是一个人要求另一个人做某事的意思。
Subject + Make + Person + Base Form of Verb
Peter made her do her homework.
The teacher made the students stay after class.
The supervisor made the workers continue working in order to meet the deadline.
Have as a Causative Verb
Have”作为使役动词表达的是这个人希望别人为他做某事的想法。这个使役动词经常用于谈论各种各样的服务。动词have有两种形式。
Subject + Have + Person + Base Form of Verb
这个形式表示某人导致另一个人采取一个操作。让某人做某事往往是用于习惯管理和工作关系。
They had John arrive early.
She had her children cook dinner for her.
I had Peter pick up the evening newspaper.
Subject + Have + Object + Past Participle
此表达形式用于通常需要付费的服务，如洗车、房屋油漆、狗的美容等。

She had the car washed at the weekend.
Mary had the dog groomed at the local pet store.
注意:这种形式在意义上与被动语态相似。
Get as a Causative Verb
Get用作使役动词的方式与have与分词连用的方式类似。这表达了这个人想要别人为他做某事的想法。使役动词的用法通常比have更习惯。
Subject + Get + Person + Past Participle
They got their house painted last week.
Tom got his car washed yesterday.
Alison got the painting appraised by an art dealer.
这个形式也用于我们设法完成的困难任务。在这种情况下，没有使役的意思。
I got the report finished last night.
She finally got her taxes done yesterday.
I got the lawn done before dinner.
Have done = Get Done
Have done和get done在过去指付费服务时意思相同。
I had my car washed. = I got my car washed.
She had her carpet cleaned. = She got her carpet cleaned.
