I have 2 questions , i know their answers , but i do not know the rule of answering , i like to hear your comments ;
Mary had her big sister -------her shoes for her .
*tie * tied
2)I had my room --------.
Paint * painted
First of all , seems the rule goes for have , make ,get .Secondaly , i think the correct answer for the first question is tie , but the second one in painted .
The difference lies in who does what. You can say:
I had Charlie paint the house - which means you paid/asked him to do it.
You can also say I had the house painted - which means someone painted it for you but the passive does not show who did it. The difference here shows that you need the infinitive if you have an object but when the action is done by someone unknown, there is no object and you use the passive.
In summary you get/have someone do something or you get /have it done.
