For American poetry, in addition to the simple elements mentioned above, I think there are two main supplements:
1. If you want to learn English well, you can appreciate the language charm of English poetry and feel the writing techniques and emotional rendering of English.
2. If you don't learn English well enough, you can look at the translated poems, but poetry translation is also a very particular thing, which needs professional poets to translate well. The translated poems often add the translator's thoughts and feelings, so it is very important to find a suitable translation version.
