Chinese Grammar learning:对 + Noun⋯⋯

When using 对 (duì) as a preposition, it is used to indicate "to" or "towards" a object or target. As with all prepositions, some care should be taken when using this particle, as usage of 对 doesn't always totally "make sense" or correspond to English at all. 

Basic Structure
The structure is basically:
对 + Object + Verb Phrase
Note that you shouldn't be plugging in just any old verb here. Certain verbs are often used with 对, and some even need 对 if you want to add an object (like 感兴趣, explained below).

Examples

对 is also used in such structures as: 对……来说 ("for… [a person]") ,对…感兴趣 ("to be interested in…") as well as 对···的印象（”the impression on the object“）
对……来说

This essentially means "for… (a person)." It's for making a statement from a certain person's point of view.
The pattern is:
对 + Person + 来说
