The english grammar rule

[emad]

hi ;

I have 2 questions , i know their answers , but i do not know the rule of answering , i like to hear your comments ;

1) 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 .

I like to understand the rule .

Hi Alan ;

Thank you for clarifing the issue .

you are right .

I will explain to you howq i was dealing with those questions type .

I had my room painted ;

I consider this sentence contains something /object which is the room so that i use p.p.

I had Chrlie paint the room ;

I cosider this sentence contains person who is charlie , so that i select the infintive .

Thanks , i think you clarified it reasonable .
