The movie teaser released Thursday, in the lead up to the Chinese New Year holiday, shows a rural man’s attempt to discover what his city-raised granddaughter means when she says “Pei Qi" —“Peppa Pig” in Chinese. 

这里的attempt后面的不定式是目的状语还是后置定语？ 

After a failed attempt to paint a farm pig red, he adapts an old ventilation fan to make it look like the character, pleasing the awaiting child. 

这句话中的attempt to do不定式是后置定语还是目的状语？ 请老师解答一下怎么区分？
