This is an excerpt from Sonnet 18 written by Shakespeare. If you know anything about Shakespeare's sonnets, you know that they always have a regular meter, which means that all of them are written in iambic pentameter. This means that the first syllable is unstressed, and it is followed by a stressed syllable.
So, when applied to this poem, just split the words into syllables - the first one will be unstressed (so, as, can, or, can), and the second one will be stressed (long, men, breathe, eyes, see).

In the sentence "We know two guides, and they gaves a tour themselves.
Us is a personal pronoun in the objective case because it is the <em>object</em><em> of the verb </em><em>gave</em><em>: gave us</em>
We is a personal pronoun, and is the <em>subject</em> of the verb <em>know</em>: <em>We know</em>
They is a personal pronoun and <em>subject</em> of the verb <em>gave</em>: <em>they gave</em>
Themselves is a pronoun used to <em>emphasize</em> the pronou<em> they:</em> <em>they themselves.</em>
