Normally the passive voice is constructed with the

verb "be" or "get" and then the past participle. However, there are

other similar verb constructions you should know about



have + the past participle




I have my oil changed once every three months.




or





get + the past participle




I get my oil changed once every three months.




Both sentences have the same meaning. What makes them

different from the passive voice is the word order




S + V + DO + V





Generally, when you use this word order, it sounds like you had

some kind of work done for you. You paid someone or got

someone to do something and you didn't do anything




He got his hair cut by a barber.

(A professional barber did the work.)





They had their house painted blue.

(Professional house painters did the work.)





She got her teeth cleaned by a dental hygienist
