I can give you a few tips on how to approach poetry, if that is what you mean.
First look at the title. Oftentimes, it can reveal something important about the poem's subject or themes in the poem.
Before you read the whole poem, read the first line and the last line. Mark the first line with a + if it has positive connotation, a - if it has negative connotation, or a ? if it seems neutral. This is helpful because if they are different, it shows that there is a tone shift in the poem. Something happens in the poem that turns it from opening positively (for instance) and ending negatively and you can be on the lookout for that.
Additionally, annotate your poem. Underline, star, or circle words that are repeated, words that are capitalized for no reason, things that are in side parenthesis or dashes. Oftentimes, larger meaning is contained within these types of things.
